The Trooper/Blazer I call Blooper.

Today's discovery, the TC shifter is hitting the seat mount. I'm going to cut more of the floor out (most of what's left). I'll remove the seat pedestals from the old floor and mount them to new sheetmetal. I can move them back a couple inches. It will give more leg room. I won't be running the back seat, so no access to the rear from the doors is needed. My ultimate goal would be to run a doubler in the future so I will have to plan for the TC going back even further.
 
I got two x-members in and have a rough layout of the center section in tape. I ordered a 4 foot wide sheetmetal brake. Time to brush up on those panel fab skills I had 25 years ago. I'll clamp the blazer steering column to the trooper pedestal and see where it lands.

I planned to install the transmission and transfer case to see where the floor was going to end up. Step one was to bolt on the flex plate. I had the wrong bolts. Flywheel bolts are longer than the flex plate bolts I needed so they were hitting the block. Nobody in town had good bolts. The auto parts stores here are lousy. Unless you go there with a part number or a picture, you might end up with a big mac instead of the part you want. They all had the bolts with star washers. ******! You need to torque those bolts to 85lbs. That's going to crush the soft star washers. It will loosen up, guaranteed. Then a cascade of failure will happen.

I tried to work on something else; strengthening the crossmembers I already installed. One thing that is challenging is that everything I'm doing is the first time I'm doing it. I've never taken a transfer case apart before. I've never built a floor in an Isuzu before. I'm having to jump off cliffs and figure out the parachute on the way down. The stock Isuzu sheetmetal evaporates when you try to weld it. That's going to add some complexity to the floor install. There is no way I can butt weld anything. If I had a torch or tig welder, maybe, but I don't. I did come up with a new injury. The burns from the chop saw sparks, the weld splatter that ends up in your ear, The cuts and bruises you get from touching the wrong thing or bumping your head are one thing. Today I put the welder down and it swung down and hit my knee. The still hot wire poked into my leg and was sizzling the flesh. Flaming acupuncture. That's a new one. I also caught my shirt on fire. Where there's smoke, you're on fire. Good thing the beard was unscathed.
 
Oy! That's no fun, but at least you cauterized it right away...
I've had success welding overlapping sheets of thing-gauge material with oversized "spot welds" of a quick circular pass over a 1/4"-1/2" hole drilled in the top sheet. With a little practice, the weld is only visible from the side that was drilled. Enough holes and the two sheets are really well stuck together

Sorry, but I need to vent. I'm ordering a lot of parts and tools online because I'm in a small town with limited resources. The tools I'm getting are junk. They fail the first time you go to use them. I was out trying to build the exhaust system today. Go to use the pipe cutter I bought. It's junk, won't even cut straight. I had a good one, but it was one of the tools stolen from my garage. Go to plan B. I'll expand the pipe and do a slip fit, a butt weld is out of the picture. Pipe expander is supposed to go to 3.5". I hit it with the impact. It bottoms out and strips the threads. Pull it all apart, find another nut, clean up the threads as best as I can. This time I go slow. Go all the way down and no expansion. I measure the OD of the expander fully topped out; 2.87 inches. Not 3.5, not even 3.0. Call amazon, cheerfully refunded on both tools. Wasted a month ordering, waiting for delivery and then getting a day free to do the work. Amazon guy was sorry, so? That doesn't help me. This is the third tool that's failed me in the last two weeks. Went to ebay. Bought a vintage pipe cutter. Another week waiting for delivery. Hope it's better. Ordered another style of expander. Not very confident it will work.

Building my first exhaust system ever. Learning how to cut the pre-bent tubes to get where I need to go. I cut the flat flanges off my headers and replaced them with V-bands. I extended the collectors at the same time. Frieburger and Dolcich seem to think it helps the bottom end. I have to re do a couple sections to get them dialed in, but happy with most of my results so far. The system is Doug Thorley Tri-y's into 2.5 tubes. They merge into a single three inch. Then a turbo muffler that goes from a single 3.0 into doubles. The doubles do a 90 degree vertical exit into a 90 degree horizontal to get over the frame rail. Then out the side of the body. Except for where the pipe goes under the front driveshaft, it's all tucked above the bottom of the frame rails.

Here is where it dips under the front drive shaft

Here is the merge before the muffler. I'm going to get the passenger side to flow in better and add a couple flex pipes just before the merge collector. There will be a V-band connector to the muffler.

I want to go out the side with a single rectangle similar to this.

I am sick of welding muffler tube. The muffler I have is single 3" in, double 3" out. I've been trying to do a difficult 90 degree turn up and 90 degree turn to the left to go over the frame rail with two tubes. I don't have a band saw, so it's been nearly impossible to cut the pipes perfectly straight and that's what it takes to make that double bend. Any gap and when I weld it, it blows out. AAAAH!!!

Then I happened to look into the end of the muffler. It's a single exit, but they weld on the end plate with double tubes. I ordered some new bends to try to get the pipe to butt up perfectly and I cut the end of the muffler off and put a flat plate on it. I'll make it a single 3" exit. That will make my life a lot easier. Problem solving.
