kurth Posted January 2, 2020 Share Posted January 2, 2020 Here is my entry for this build off, an early 2000s boxing of the AMT chevy Bison I decided to get right to work and assembled much of the engine I decided to stop here so I can do some research and see how this engine should be painted I also assembled the transmission. It has a really big seam on the bottom which will require attention I wanted to press on and start the Frame, but I am getting tired and need to be able to concentrate, so I will pick it up later. See ya next time! Quote Link to comment Share on other sites More sharing options...

I also plan to use a Detroit diesel engine in another wild project, so this will also serve as a test fit article, to see if the other project is feasible.

kurth Posted January 5, 2020 Author Share Posted January 5, 2020 I have assembled the frame The instructions are not clear, but I looked in later steps in the instructions and got a better idea where the cross members were supposed to go. I glued the parts in place with liquid cement to get a good plastic to plastic welded bond I left it for two days and glued the other frame rail in place tonight One rail was warped, and I think at least one cross member was not quite perfectly straight so hopefully the frame is not too far out of square ... we will just have to see. There is a lot of flash on the parts. some parts only have a little bit of flash, and in that case it is almost worse because it is very subtle and hard to see, and it is hard to tell where the part starts and the flash ends. I think I will get the rst of the suspension together before painting, I want a good plastic cement bond for the leaf springs and diffs, but it will be a bit harder to ensure complete paint coverage in every nook and cranny.

vettecote Posted January 5, 2020 Share Posted January 5, 2020 Great project! I'm guessing that's an 8V71?...Joe Quote Link to comment Share on other sites More sharing options...
gotnitro? Posted January 5, 2020 Share Posted January 5, 2020 Moving right along ! You found out the hardest part of big rig building, questionable instructions and flash lol Your knocking right out though . Building the suspension off the frame can help coverage just be sure everything will fit after on chassis. I messed up once not having it square and it didnt want to fit .

tbill Posted January 5, 2020 Share Posted January 5, 2020 As to the paint coverage, I like to glue as much as possible to the frame before primer/paint. What I do is prime in gray model primer , then use an automotive primer that is close to the frame color, I find you can put quite a bit of primer on before it runs/sags/pools up, being close to frame color helps hide some of the areas you can’t quite get to with the paint ( without making the paint run/sag) Quote Link to comment Share on other sites More sharing options...

I think it's supposed to be a 8V-92 and that goes for both the Chevrolet Bison and GMC General. Quote Link to comment Share on other sites More sharing options...
kurth Posted January 11, 2020 Author Share Posted January 11, 2020 Work continues but I am stumped .... I started the front suspension, but the unclear instructions strike again. It points to a vague area to glue the front leaf springs to the frame. There are holes in the frame but no pin on the leaf spring shackle I think The best course of action will be to mock up the body and see where the wheel opening is, then use that as a guide to locate the front axle. I also had to use putty on the differentials, there was too much of a step to sand it smooth Once I figure out the front axle, I can assemble the rest of the chassis and paint it.

gotnitro? Posted January 11, 2020 Share Posted January 11, 2020 Your doing very well ! Also finding out the head scratcher moments building trucks sadly . So many times these issues arise , but they seem to work out . Mocking up the body over frame does help get suspension lined up Quote Link to comment Share on other sites More sharing options...

kurth Posted January 22, 2020 Author Share Posted January 22, 2020 No, I did not abandon this one. After over a week of putting this one aside in frustration, I got the kit out and I mocked up the cab so I could figure out where to put the front axle. I mocked up a wheel/tire assemble to get the best possible idea of how the tire will sit in the fender opening I traced the position of the spring shackle on the frame with a pencil So, now the other front leaf spring has been glued to the axle and the glue is drying. Now I can pick up some momentum on this one in the next few days. Quote Link to comment Share on other sites More sharing options...

What I found is that in a couple of spots the paint "bubbled". What "automotive primer" spray paint are you using ? Thanks ! Quote Link to comment Share on other sites More sharing options...
