What a pain. The transition from lift gate to floor was totally screwed up from years of driving the pallet jack over it. I didn't take any pics of the before but it was basically vertical in the center, to the point of the electric pallet jack not even being able to drive over it anymore.

A good amount of time was spent heating and beating it to get it somewhat straight and down. I added some flat bar welded to the transition and countersunk screws thru the aluminum floor into the whatever plastic material under.

Looks like it will work out good enough to get this truck back into service. I've done quite a few of these bobtail trucks and it seems like they are all a little different in their construction. Some are pretty easy to fix, some are like this one. Lol

T25/T28 5 bolt to 3" v- band adapter. Purged stainless.

I have a full 3" stainless exhaust kit, so I'm going to make a new exhaust for the turbo car. It should be better than the 2.5" that's on the car currently.

I built the 2.5" for the car when it was still na so i added a bunch of resonators and such to get the volume down a little bit.

With the turbo, I'm going to get the restriction down a bit so it minimizes back pressure and hopefully sounds pretty good

An aluminum guard rail / sprayer mount repair on a hydroscape truck. It was broken pretty bad on both sides. I added the gussets for more surface area of weld.

I was going to do fish plates but the tubes were varying thicknesses so i would have had to bend ΒΌ" 6061 in the field.

This is an automated rollout wheel. I've been looking at the standard (manual) ones for a while but they are a little expensive. Motorized ones are way out of the budget.

A few years ago i made a rotary table for the mill using an old flywheel from an sr20 and some large bearings.
I recycled some of the parts of that project into this one, but i needed to make some modifications to make it work vertically instead of flat on the table. Mostly it needed a new center hub design as well as one standard and one thrust bearing.

I went with this style lathe head for a few reasons. It's slim and therfore lighter. It has a large vareity of grip range. And finally it didn't require any keys to open/ close it. This final reason turned out to be not so great, but it is what it is. Just have to lock it out to open/ close it.

After i got the lathe head mounted to the flywheel, i was like hey let's use these teeth....Instead of having a bolt to lockout the head from turning like most rollout wheels do, i made a little chunk of flat gear with a left hand thread mechanism to lock the wheel out.

I've been playing with stepper motors and controllers on my other welding positioner project, so i got more parts. I had the drive gear from a starter that i initially used for the rotary so i got a stepper with that size bore. I made a mount for the motor with adjustability for back lash, and got it running both forward and backward with speed control (very slow stable speed being the requirement)

In trying to come up with some fancy way of getting the pipe level, i did a temporary bolt adjuster. I realized that i could also flip the chuck up flat for a mobile horizontal positioner as well as the current vertical. So the temp bolt adjuster is now good enough. Not fancy but functional.

I then had to make the lockout arms to hold the thing up flat and not come crashing down. It's heavy. The arms took a little trial and error and a bit of computer aided guessing. I only had to scrap one part! Lol. But in the end i got it to clear "down" and fully lock it "up".

I also made an arm that goes into the tow hitch for this thing to sit into. I didn't take a pic of that but it's just a big 90 arm to clear the lift gate of the armada (weld rig)

I did a bench test and it will work on 12vdc, but the motor really wants 24 to 36vdc. I have a power supply that I'll wire up to 110vac, but i could theoretically run it off the car battery.

All and all, it took some time but it works great. I used it in the shop to weld up axles and flanges on my son's go kart project and it was awesome. I can't wait for the next pipe or exhaust job so i can really test it out.

Adjustable width roller wheels to sit atop my pipe stands. I only had enough material to make one set of rollers for now, but I'll make a 2nd set in the future.

I made the roller so it locks into the head of the pipe stand. It's so annoying when you accidentally knock them off. Lol

I made a man door to match the surrounding security fencing. They supplied the mechanical combo lock and panic bar. I've made a few ornamental iron gates and stuff back in the day, but never one that incorporated a panic bar. It's a little different in the way everything goes together and the offsets are odd, but it was nice to go back to my roots of getting paid to weld when I was in my teens.

It's interesting that a basic door like this takes pretty much the same amount of time as some elaborate ornamental iron one does. The design time is vastly different but the actual fab time is about the same.

...And they're finished. Talk about a side project. In the end, I'm pleased with the results. No more burning the silicone plugs that catch fire and screw up the argon flow. I'm sure I'll think up more ideas for other complicated purge plugs.

The aluminum plugs that can be purchased are pretty expensive. I got a foot of 3" 6061 for around 50 bucks, turned on the shop TV, and sat at the lathe for longer than I expected. Lol

The stepped plugs are for 2, 2.25, 2.5, 2.75, & 3" stainless exhaust tube. They are designed to be a snug but not press fit.

The taper plugs are universal to cover the 2" to 3" with varied wall thickness.

The v- band plug is for 2.5" and doubles as a heat sink along with the argon purge.

All the diffusers have quick connect fittings for my dual regulator output hose.

Labor day c-notch for a customers Silverado. I didn't take any pics but luckily the customer did. Lol. I forget to take pics for this page too often. In any case he bought a kit just needed it burned in.
