READ BEFORE BEGINNING CONSTRUCTION Material, Tools, & Techniques Power and versatility in a small economical unit makes CADDigger a desirable machine to own. The machine can perform digging tasks better than a farm tractor, yet doesn't disturb the soil like large machines. A great deal of time was spent developing CADDigger so it could be built with only a few metal working tools. Mechanical tubing is a heavy wall steel with a precision inside diameter. It is not pipe. Using this material, you cut a piece, weld it in place and have a precision hole. Weld two aligned with a pin and you have an assembly only a very big machining center could produce. Those customers who have the machines available to them can weld bar stock in place, lay out the holes, and drill & ream the holes to produce CADDigger. This is a successful technique, but CADDigger was designed for the home owner without machines or machining skills. The only tools typically needed to produce CADDigger are a drill press, welder (stick preferred), bandsaw, electric drill and hand tools. Other tools are helpful, but not necessary. If you have other tools (lathe, mill, etc.) and know how to use them, do apply them to CADDigger. The techniques used are the latest applied by equipment manufacturers. Low tensile strength castings are being abandoned for steel fabrications. Steel is a very forgiving material to work with allowing you to cut and drill with little practice. Unlike castings or wood used in other projects, steel can be easily repaired should you make a mistake. And since the parts are so simple, don't feel bad about abandoning a part and starting over, which is better than having a defective part in your machine. Always remember, you are quality control. Make that part right now so you won't have a problem later. Preparation Excavators and backhoes are notorious for the extreme power they can generate. From the first time hydraulics were applied to a shovel man knew this was the way to dig. This must be remembered when building CADDigger, the joints and assemblies are subjected to high forces. Take your time during construction, align parts carefully and weld all parts fully wherever they touch. Use full size fillet welds. This means each leg of the fillet equals the thickness of the thinner part being welded. (See Fig 1.) Note:
Large fillet welds may cause parts to draw together. These areas require the minimum size weld. Take your time when cutting parts with the bandsaw. Increasing down pressure to increase cutting speed causes premature blade failure and crooked cuts.

The more precise your parts are cut the easier your assembly will be. Torch cutting and abrasive wheel cutting can produce good parts in the hands of skilled craftsman, but the bandsaw produces quality parts almost all of the time. Precision alignment of parts comes from fixruring during welding. Block parts with steel scraps during welding to minimize ther th erma mall dist di stor orti tion on..
Build the mac hine on a level sur face. If you set up the frame on an unleveled unleveled surface, surface, obtaining obtaining squareness squareness will be difficul d ifficult. t. If the machine ma chine is not square, it will not not dig properly properly and will not tow straight straight when converted or trailering. Tack weld an assembly prior to welding and check for accuracy. A tack weld can be easily removed, where as a completed weld can cause you to scrap a part that was misaligned. Thermal distortion will require you to hand adjust the holes. This is normal. The more even the temperature a part remains, the less distortion will occur, but distortion will occur. Test fitting pins in holes will reveal distortion. The hand reamer recommended in the instructions makes quick work of the 1" holes. If a pin is stationary in a hole (such as the cylinder pin holes in the boom), precise fit is not always mandatory. I have been known to install a pin with a ball peen hammer with excellent results. results . This is not

Grind and ream as necessary to make the mating pin fit the hole. Don't scrimp on effort here, as a quality fit will result in a quality machine. Hydraulics Hydraulics hoses are usually least expensive pre-assembled in standard lengths. Use hoses rated 2000 psi min. working pressure or greater (not bursting pressure). Use the hose size that matches your components. Any hose 1/4" ID or greater is acceptable. Matching hose size to cylinders and the valve will reduce the number of adapters, which can cost as much as the hoses. Hose lengths are not given due to various components used, just insure the hoses are not stretched when the machine is moved through its travel. Only couple hoses with high pressure couplings. Parts available at the hardware store are not high pressure rated and can burst. The open center stack valve recommended is straight forward in design, (1) inlet, (1) outlet, and (2) connections for each cylinder. The inlet is the side with the pressure relief valve built in. If you reverse the inlet /outlet you will blow an o ring out of the valve or possibly have a more serious result. Be careful with this connection. Monitor the oil temperature closely. Serious injury to the operator and/or the machine can result from oil temperature above 130 degrees F. Bronze Bearings (or Nylatron Bearings) Check for these at a store in your yellow pages under "Bearings". Be sure to get "finished" ED & OD as bronze bearings are available to "Rough Dimensions" Dimensions" with with extra material for final finishing. finishing. Rough dimension bearings are OK if you have a lathe and want to turn the bearings for fit. Use care when pushing the bearings in the mechanical tube. Too much force pressing in the bearings will crush the ID, which will then require reaming. Use a hand grinder or a file to grind a groove Fig.2 Grease Groove in Bushing around the bearing where the grease hole will be (See Fig. 2). This will insure grease can still get in the bearing if the bearing rotates. MetKit Corp. supplies Nylatron nylon bearings, which will outlast the bronze bearings. Grease fittings are optional with Nylatron as the bearings are impregnated with lube. Just apply grease at assembly and use them. The MetKit bearings are finish machined to fit the pins and mechanical tube. Bucket Teeth I have not recommended a specific brand of bucket teeth but just about any kind of small to medium tooth will do. Maintain 105 degrees between the leading edge of the bucket and the teeth. If you wish, you can fabricate the teeth. Simply cut some 3/8 steel 1 1/2" wide x 2 1/2" long. Cut a support from 1" x 1" x 5" for each tooth. Grind an angle where the support will hold the tooth so the tooth will be at a 105 degree angle to the leading edge of the bucket. Grind the back of the tooth to 15 degrees for relief so the tooth will cut. Hard surface weld on the front of the tooth increases the life of the tooth. One bead around the front surface is usually enough. Operating Tips Take your time learning to operate CADDigger. Notice CADDigger works by "clamping" earth between the teeth and the stabilizers. Don't try to push the bucket into the ground more than a couple of inches. Keep the teeth cutting towards the stabilizers and you will be pleased with Fig Fig. 3 View of As Assem sembled CA CADDigger Bu Bucket
CADDigger's power. If you encounter a rock too big for CADDigger to handle, dig a hole next to the rock and push the rock into the new hole. If you still can't move it, talk to your dynamite expert. Have fun with CADDigger and send me a photo when you finish. CADDigger is built from the drawing package, photos and video. Carefully watch the video to help you learn special construction techniques and tips such as hole fabrication, bucket construction, and hydraulic circuit construction. 4
CADDigger 650 CONSTRUCTION General Tips => It is recommended that all holes up to 1 1/2" diameter are drilled. If you cannot drill holes up to this size, they can be fabricated by cutting a larger hole with a hole saw or torch then welding in a piece of mechanical tube. => Some mechanical tubing or drawn over mandrel (D.O.M.) tubing runs undersize inside. If the material you find is undersize on the ID, use 63/64" steel roundstock to fabricate pins or you must ream to 1.002" ID. This can be done by hand if removing less than .015". An alternative to reaming the 1 1/2" inside diameter of the mechanical tube would be to reduce the OD of the cast bronze bushing so that it will fit in the mechanical tubing. This can be done on a lathe or by hand such as carefully reducing the OD with a belt sander and repeatedly checking for fit. Do not us a heavy press fit or hammer in the bushing as this will crush or reduce the ID and the pin will no longer fit. => Use high strength welding techniques such as 6011 or 7018 stick welding electrodes. Avoid lower strength welding processes such as 6013 stick welding electrodes or small flux core or MIG welders. Consult a local welding supply or CADplans if you have questions. => Tolerance buildup and variation in components used can cause the swing cylinder rod to hit the boom pivot corner. Insure the rod does not hit the pivot when the cylinder is fully extended. In order to fix this situation if it occurs, bevel the corner of the boom pivot until the required clearance is achieved. The correct location can be determined by trial and error. => You may deviate from specified items if you find alternates with the same generic specification (such as valve, pump, etc.) => All steel is hot rolled, unless otherwise specified. Cold rolled may be substituted, but is not required. => Alignment of parts within an assembly is best accomplished by assembling the mating components while tack welding. For example, when tack welding the boom, assemble the two cylinders to insure they are parallel to the boom. Also assemble the boom extension to insure the boom extension is parallel to the boom. This technique will insure the mating components will mate and are properly aligned. You can even move parts through their motion to insure they function prior to final welding. => Anchor pivot pins. Pins on the main pivot and boom must not turn or excess wear will result in the steel part. I have successfully anchored these pins using a bolt-weld combination. To weld, use a 3/16-1/4x1x3" section of steel bar welded to the pin and then bolted into the corresponding bracket (see Sheet #16). Pins that rotate very little, such as the rear pin on the boom extension cylinder and the bucket curl cylinder, can use the bolt-weld combination or a bolt & nut. If a bolt & nut is used in any pin application, make sure that clear bolt (no threads) ends up against the inside of the mechanical tubing. The pins used in CADDigger's pinned joints can be substituted with grade 2 bolts. The bolts you obtain must have a good quality finish so they will run smooth inside the bushings. Use caution welding the pins. High strength materials must be welded with low hydrogen rods to eliminate cracking.

Instructions STEP 1 => OBTAIN HYDRAULIC CYLINDERS. => Obtain your hydraulic cylinders prior to the construction of the pivot, boom, boom extension, or stabilizers. The closed-pin center-distance and the stroke-distance must match the hydraulic specifications to insure proper operation/rotation. The CADDigger is designed to account for small variations due to measurement errors during assembly. STEP 2 => FABRICATE FRAME => Use Diamond plate specified on Sheet # 325. This is an important safety feature to ensure the foot rest or step of CADDigger are a non-skid surface. Oil will occasionally be spilled on CADDigger during assembly and usage. If a hose should fail during operation, you want to maintain a sure footing. => Fabricate frame as shown on Sheet #301. STEP 3 => FABRICATE THE BOOM PIVOT => Follow Drawing Sheets # 302 and #303. => The pivot has 4" of clearance between the plates that attach to the swing hydraulic hydraulic cylinder. You should cut and insert sections of mechanical tubing that position the cylinder properly (Sheet #327). STEP 4 => FABRICATE STABILIZERS => Follow Drawing Sheets #304 through #311. => After you have attached the stabilizer to the frame fabricated on Sheet #301 and installed the pivot to the frame, slide this assembly into CADTrac CADTrac as shown on sheet #310. You should have 2.5" clearance between item #302 #302 and the receiver receiver tube of CADTr CADTrac. ac. 0 The .75 " holes dime nsione d on Sheet #309 must line up with hole s in the CADTrac frame as shown on Sheet #310. Therefore, you may want to weld items #319 and #320 to the CADDigger's stabilizers when the CADDigger Frame/Stabilizer Assembly is slid into CADTrac. This will ensure hole alignment. STEP 5 => WELD SWING CYLINDER REAR MOUNTING BRACKETS TO CADTRAC FRAME => In the previous step we assembled the CADDigger Frame/Stabilizer Assembly to the CADTrac frame. => Assemble the boom pivot fabricated in Step 3 to the frame. => Assemble the swing cylinder to the pivot as shown on Sheet #321. Extend this cylinder fully. Rotate the boom pivot to the right until the cylinder is positioned V" from the frame. This will position the rear hole of the swing cylinder very close to the position shown on Sheet 327. Place a pin through the rear of the swing cylinder and the Items 352 and 353. => Weld the rear cylinder mounting brackets to the CADTrac's frame as shown on Sheet #327. This is the correct technique to assemble the swing cylinder mounting brackets. If the rear mounting brackets are assembled to the dimensions shown, it is highly likely that the swing cylinder will be improperly positioned and might allow the cylinder to contact the frame. STEP 6 => COMPLETE THE FRAME ASSEMBLY => Follow Drawing Sheet #324 and #325. => The CADDigger seat assembly is designed to lift off for access to the the engine. Its travel down down is stopped stopped by the piece of ½ “ x 2"x 7" bar that is welded to the seat post. The 1/4" bar is also the mounting bracket for the stabilizer control valve. => The 1/4" x 6' x 9" vertical plate is positioned properly for the use of a FPS valve body using joy sticks or straight handle control levers. If you decide to use 4 control levers instead of joy sticks, sticks, simply bend the levers so they point point straig straight ht up. up. Note: This frame assembly of Items of #333 through #351 are designed to accommodate FPS valves and 3/8"NPT hoses and fittings. If you use different valves and/or hose sizes, you may have to adjust the size of the hoses and valves you have acquired. 6
STEP 7 => FABRICATE BOOM AND BOOM EXTENSION => Follow Drawing Sheets #312 through #313. STEP 8 => FABRICATE BUCKET => Select which size bucket you want to fabricate. Two different buckets are shown. You can fabricate any width bucket you prefer by modifying the length of items #331, 332, 333, 334, and 337 to suit your needs Note: On Sheet #318, a 1-1/8" hole is shown in Item #335. This is correct. This is not a hole that a pin bears against, it is simply a clearance hole to allow installation of the pin.
=> Fabricate the bucket as shown on Sheet #316 or #317. STEP 9 => RETAIN PINS WITH SPACERS => Cut pins to length and install with the retainer as shown on Sheet #319. => Center cylinders using mechanical tubing as spacer, custom cutting to fit as shown on Sheet #320 STEP 10 => PAINT => Prime with a good zinc oxide or damp proof red rust inhibitor. => Top coat with an exterior enamel enamel for metal. STEP 11=> MOUNT VALVES => Mount valves as shown on Sheet #326. STEP 12 => INSTALL HOSES AND FITTINGS => Hose connections from the 4 section control valve to the backhoe cylinders are shown on Sheet #322. Typical fitting installation is shown on Sheet #323. Your fittings may be different than shown on Sheet #323 as this is an illustrative-only drawing showing positions of the fitting and ports in relation to the valve. Refer to Hydraulic Fittings shown on Sheet #323 for the correct fitting description to attach each hose. Next, use an SAE 6 to 3/8NPTF adapter and connect a 60" hose to the power beyond port of CADTrac's loader valve. Install a male half end of a quick coupling to this hose. Install a female half to a 24" hose and using an SAE 6 to 3/8NPTF adapter, install this hose to the inlet of the 2 section stabilizer control valve. Install a SAE 6 to 3/8"NPTF 90 deg adapter to the power beyond port of the stabilizer control valve. Install an 24" hose from the power beyond of the stabilizer control valve to the inlet of the 4 section backhoe control valve with a SAE 6 to 3/8NPTF adapter. Install a SAE6 to 3/8NPTF and two 24" hoses in the outlet of both the stabilizer and backhoe valves. Use a FFF3/8NPT Tee fitting to connect these 2 hoses and a 24" hose to a male half of a quick coupling. Connect the female half of this quick coupling to the return line of CADTrac as shown on Sheet #OP1. Also see photos for other details. STEP 13 => HYDRAULIC ADJUSTMENTS => Do not exceed 2000psi. See further instructions under Purchased Equipment Specifications, Hydraulic Valve Bodies. The Loader control valve must also be set at 2000 psi or the relief valve in the loader control valve will control the pressure available at the stabilizers and backhoe. This is because the power beyond port is supplying oil to the stabilizers and backhoe circuits. STEP 14 => SEAT WITH ENGINE ACCESS => The seat bracket slides onto the seat post. This design allows easy removal for access/service to the engine. If you prefer, you can drill a hole through the seat bracket and the mounting post and pin the seat in location. STEP 15 => REMOVAL OF THE CADDIGGER => To remove the CADDigger, lower the stabilizers and bucket. Remove the pin from the swing cylinder. Remove the two 5/8" bolts. Un-couple the quick connects from the backhoe. Re-couple the hose from the loader's power beyond port to the return line quick connect half. Start the CADDigger and drive the CADDigger away from the CADTrac .
PURCHASED EQUIPMENT SPECIFICATIONS HYDRAULICS: CADDigger is designed to operate using open-center-hydraulics. This ensures that the pump continuously moves oil through the open-center of the valve body as long as the pump is running. Oil flows at low pressure in the hydraulic system until the operator moves one of the control levers.

HYDRAULIC VALVE BODY: CADDigger needs a 4 spool valve body with integral relief valve. The spools must be 4-way, 3-position, and springcentered. The hydraulic valve has the relief valve built into it. Typically it is a screw that presses on a spring located on the inlet side of the valve. The higher the hydraulic pressure, the higher the pressure is on the spring. HYDRAULIC VALVE BODY (Stabilizers): CADDigger needs a 2 spool valve body with integral relief valve and power beyond. The spools must be 4-way, 3position, and spring-centered. The hydraulic valve has the relief valve built into it. Typically it is a screw that presses on a spring located on the inlet side of the valve. The higher the hydraulic pressure, the higher the pressure is on the spring. The relief valve in this valve must be set higher than the backhoe valve. If this valve is set lower, this relief valve will relieve the backhoe valve also. HYDRAULIC VALVE BODY (Loader): CADTrac needs a 2 spool valve body with integral relief valve and power beyond. The spools must be 4-way, 3position, and spring-centered. The hydraulic valve has the relief valve built into it. Typically it is a screw that presses on a spring located on the inlet side of the valve. The higher the hydraulic pressure, the higher the pressure is on the spring. The relief valve in this valve must be set higher than the stabilizer or backhoe valve. If this valve is set lower, this relief valve will relieve the stabilizer and backhoe valve also.
HYDRAULIC HOSES: Hydraulic hoses can be Obtained from various sources. Select a length long enough to ensure the boom can swing through its complete travel both side to side and up and down. Select hoses with fittings that will attach to both the cylinder and to the valve body. The best sized hose is that which has fittings that match your cylinders and valve to reduce the number of adapters. A 1/4" ID is the minimal hose size. The hose lengths below must be modified if you use a different valve, etc. One wire hydraulic hoses are recommended. The two wire hoses operate at a higher pressure but offer a limited flexibility. flexibility.
