Re: Wampus Cat
More Bed Work
I had been delayed for a little while in finishing the paint stripping because I couldn’t find more of the abrasive fiber discs that I was using for that. I recently found some more discs, and started up again on stripping paint from the inside of the side panels and the fender wells. I also drilled the ¼” tread plate floor for some lifting eyes which can eventually be used for tie downs. I’ve welded nuts to the underside of the treadplate so that the eyes can be unscrewed and removed from the top. While doing the paint stripping, I noticed that the metal panel below the tailgate was bent inwards about 3/8”. Not sure why I didn’t see that before, but I’m guessing that the damage was done when the tailgate was bent (see tailgate straightening in post #161 above). In any case, I rigged up a fixture with a few blocks of wood and a couple pieces of angle stacked on top of each other for stiffness. With this, I could use a large C-clamp to pull on this lower panel and its supports to straighten it. After working my way back and forth across the panel, pulling with the C-clamp, I was able to get the panel straight within about a 1/32” compared to a 4 ft straight edge. .

Re: Wampus Cat
Work Shop Art
My sister recently gave me a birthday card on which she had water-color painted my truck modeled from a picture taken before I disassembled the truck for rust/body repairs. The picture on the card is 4"x6", but I made a copy printed at 11"x14" and added it to the work shop art. .

Re: Wampus Cat
Power Steering
I found a 1984 C10 power steering gearbox and a steering column collapsible lower section at a local Wrench-A-Part. The gearbox seems in pretty good shape, smooth operation and no substantial backlash. However, it was apparently leaking, so I installed a pitman arm shaft seal kit and an input shaft seal kit. Big thanks to Tx Firefighter for his excellent instructions on seal replacement! http://67-72chevytrucks.com/vboard/s...d.php?t=619634 I also bought a Captain Fab power steering gearbox mounting bracket which is supplied with a very useful mounting template. I punched holes in the template at the old/existing bolt holes, then using three of the old bolts, aligned the template to the existing bolt pattern in the frame and matched punched the locations for drilling the new holes. A test fit of the new gearbox appears to show everything in alignment, so I’ll weld the new bracket to the frame (optional) and then clean/paint/install the gearbox. For attaching the collapsible steering column section to my existing steering column (which is a three on the tree standard shifter), I intend to cut the existing steering column at the right length and then grind/file the double D flats on the end so that it matches the collapsible shaft. I bought a Unisteer 8050300 ¾” DD x ¾” DD U-joint to attach the two shafts. I particularly like this Unisteer item because it clamps on to each of the shafts rather than having through bolts or some other means of attachment. Plus the clamping bolt requires a slight cross groove cut in the shaft for the clamp bolt to pass; this feature also prevents the shaft from pulling out of the u-joint. Seems like a pretty sturdy attachment configuration.

Re: Wampus Cat
I decided to completely rebuild the front suspension while switching from a manual to a power steering gearbox.
I had previously installed 2 inch lowering springs and new upper ball joints when I rebuilt the brakes. At that time, my inspection had led me to believe the rest of the suspension and steering linkage was in pretty good shape. However when I started disassembling things, I found more wear than what I could find with the suspension or steering all assembled. For example the rear bushings on the lower a-arms were worn very badly even though I could not feel movement or wobble in the a-arm. Fortunately the threads in the a-arms for the bushings were not damaged. I’m currently in the process of cleaning and painting all the parts and installing new Moog parts. I’m also making the modification to improve caster by moving the A-arms 3/4 inch forward. I decided to compensate for that by modifying the shock absorber mounts on the lower a-arm to move them back to their approximate original position to maintain the original shock orientation. Oh, I also recently found a basket-case, badly used/abused 20-ton hydraulic press and refurbished it for use in the shop (rebuilt the hydraulic jack; found or made replacement parts; straightened bent parts; fabricated a caster base). The press worked great for removing the old lower ball joints. . .

Re: Wampus Cat
I recall rebuilding my upper and lowers.
My one lower is a replacement as the truck must have had a serious hit at some point in its past. Looking good.

Re: Wampus Cat
I finished the installation of the power steering gearbox and the rebuild of the front suspension which were started in posts #175 and #176 above.
I used the collapsible steering column section that was attached to the Wrench-A-Part ’84 C10 power steering gearbox. I cut my existing three-on-the-tree manual column a few inches below the shifter mechanism and used a cut off wheel to rough cut the ¾” DD shape, then finished it with a file to get a nice tight fit in the Unisteer U-joint. I initially planned to do the caster improvement modification by moving the A-arms 3/4 inch forward, but when I mocked this up I found that the coil springs rubbed on the inside of the upper spring pocket. When I bought the 2 inch lowering springs they were described as heavy duty, higher rate springs and I suspect that they are larger in diameter than stock. In any case, when I drilled the lower A-arm shafts, I only moved the locator pocket by ½ inch instead of ¾ inch. That seems to work with the springs, and I get at least some of the caster improvement. The power steering gearbox adapter plate from Captain Fab and the Moog “The Problem Solver” front suspension parts all made these tasks go pretty smoothly. .

Re: Wampus Cat
Cab Removal
I've been doing all of my rust repair and metal work with the cab on the frame, and hadn't planned to remove it, but then I realized that in its current state of disassembly it only took removal of about a half dozen bolts, wires, and steering column to set it free. So, after seeing some other posts about applying Raptor Liner to the cab underside, I decided I wanted to do that to protect all of my work. I made a simple wood support frame to fit inside the cab, and notched it to fit around the weatherstrip flanges on the door openings. I then attached that to my overhead hoist (see post #111) and lifted the cab. After rolling the frame back out of the way, I then set the cab on the floor and moved the hoist straps to the two inner-fender attachment points on the front of the cab, and hoisted from those points so that I could pivot the cab on its back on to a pallet with casters. This worked really well to single handedly remove the cab. I did bend one of the drip rails slightly with the lift strap, but this is an easy fix, and I'll add some features to the wood frame to prevent that before the next lift. Next up is wire brushing the bottom of the cab, degreasing, cleaning, and applying the Raptor Liner. .

Re: Wampus Cat
Rolled the cab back upright after coating the bottom, and mounted it on a cart for body work.

Re: Wampus Cat
txcajun why did you want more camber ? is that a problem with these trucks? 3/4 of an inch sounds like a lot or is that what is recommended? I don't understand front ends much so what dose the extra camber do to the driving quality? Thanks Denis

Negative Camber vs. positive Camber is also an improvement that allows for better tire contact when navigating corners.

Re: Wampus Cat
Thank you all for your kind words regarding progress!
With the help of my brother who is visiting, we finished a little metal working, clean-up, and epoxy primer on the bed this week. .

Re: Wampus Cat
After the primer cured, we installed the bed front and the tailgate.
I plan to leave these installed with the bed on the cart while doing the body filler work and sanding in preparation for the next primer stage. .

Re: Wampus Cat
Not exactly truck related, but sort of. How much of a total run do you have in your copper pipe air dryer in the background. I will be building on of these in the spring. Does it work well for painting and anything you would have changed? Just looking for advice before I build mine.

Thanks for the question! Most visitors to the shop don't know what that is. :-) The 8 straight vertical sections of 3/4” diameter tubing are 5 feet long each so I would estimate that the total length including all of the fittings is about 45 feet. It can be pretty humid here in central Texas, and this arrangement works well so far. I don't get any moisture out of the last drain valve, and you can progressively see less moisture from each drain valve as you get further from the compressor. When I'm running the compressor hard for painting or sandblasting, I generally drain the compressor tank and all the tubing drain valves about every hour. I've only done primer painting, some Raptor Liner, and sand blasting with this arrangement so far, but I have had no water issues. I do have a small filter dryer at the end of the run as a final stage backup. With regards to changes I would make, if a person had a way to bend the tubing and eliminate some of the solder joints/fittings, that would make the assembly easier and reduce the number of potential leaks. Also, I'm thinking of adding an automated drain valve for the main compressor tank. Beyond that, I'm pretty happy with the results. Just as an fyi, I bought the long runs of tubing in 10 foot sections locally at a big box store due to shipping costs. All of the fittings were sourced from Zoro.com as they appeared to have the best prices, and I think all of the ball valves used for the drains were Harbor Freight. Three years ago, the parts were around $80 total. .

Re: Wampus Cat
Maybe my logic is flawed, but my air setup is long horizontal runs rather than long verticals. The runs are angled down slightly ~.25"/foot. Water has to drain back to the tank or blow through the water separator. I don't like the 5 valves that have to be drained after water condenses or it gathers and turns real nasty.
I used black 3/4" pipe and made it modular with unions in the verticals so I can add 40' sections easily. The filters, regulator and dryer is also attached w/ a union so they come off as a ~3' section. |

I did this using cheap Northern Tool China sourced 50' neon-orange airline on my garage wall after looking into a copper plumbed arrangement. I figured while the copper would offer better cooling vs the plastic hose, the hose should still be effective & was much cheaper/faster @ the time. I originally routed the airline in angled sloped runs but changed it to vertical runs w/drains @ the bottom of each loop like TxCajun. I came off the compressor discharge & straight into the cheap hose. Each run up the wall had a brass drain tied in @ the bottom (180° loops top & bottom). The very end of the line had a drain as well & the discharge routing back into the compressors tank was 'T'd inline18" above the 'end of loop' drain. It was all tied together w/serrated fittings & worm-gear style hose clamps. Worked well & allowed using my plasma cutter w/o issue (that was my main reason for the set-up. PC's apparently DO NOT like moisture). I took the set-up down when I moved out of the house. it lasted far longer than I expected given the hose quality (~9yrs w/o issue).

Re: Wampus Cat
My original chrome bumper was very scratched, dented, bent, cracked in several places, and rusty.
While my brother was visiting, and I had a second set of hands available, we used my 20-ton hydraulic press to do our best at straightening it and pressing out the dents. I then welded and ground the cracks. Afterwards, I stripped the remaining chrome and rust with an abrasive fiber wheel, and finished with 120 grit sandpaper. I applied Krylon primer, then a couple of coats of Krylon “metallic aluminum”, which looks pretty sharp, but is maybe a bit too bright. I then applied Krylon “gloss, crystal clear coat”, and that turned it into more of a subdued finish, which matches what I’ve done on my rear step bumper. The things I’ve read on the interweb say that Krylon Clear won’t yellow in the sun, so we’ll see how it holds up.

Re: Wampus Cat
TxCajun,
Thanks for the info. In MD where I am, it also gets very humid in the summer. I will check the online source for the fittings. Copper has gotten very high at least where I am. for the 3/4 inch pipe, it is going to cost me more then that. I too was figuring I would need a filter/dryer of some sort at the end of it just as a precaution. I don't plan on opening a paint both or anything like that, but do want things to look decent. I have other painting projects besides the truck stuff. Thanks for the info. |
