I finally got some real progress done on an engine stand for my 392 Hemi engine project. I briefly mentioned it in an earlier thread. I'm hoping for some warmer weather next week so I can finally get some paint on it. Hopefully next weekend it will be finished! Then I can get on with finishing up my torque plate, and FINALLY pressure testing my block.
I was fortunate enough to have everything I needed for this project by digging through what my wife calls my "Junk" or "Crap" pile. Of course, I call it my "Interesting Stuff" pile.
Most of the material I used is pretty rusted and pitted. I spent the better part of an afternoon burning up a wire wheel to remove most of the rust. The square tubing is pretty pitted, but primer and paint will hide most of that. I also end up machining a lot of the rust away on the other parts. I got the wheels for free from a friend who didn't want them:
A pic of starting to turn on the main shaft, 3 3/4" diameter solid steel:
Working on the headstock sleeve for the main shaft, 3 3/4" by 3/8" wall DOM tubing by 8" long:
I managed to find a couple of big bronze bushings for the headstock that holds the main shaft. 3" bore for the front and 2.8" bore for the rear. I would have preferred to make them the same size, but these where bronze bushings I already had in my secret-stash pile. I carefully turned the O.D. of the bushings to give them a 5 thou interference press fit into the headstock. You can also see the slight lead at the end where I turn down the bushing a little to help it get started during the press:
After welding on the uprights, I carefully pressed the bushings into the main headstock sleeve:
Of course the headstock sleeve gets a little distorted from welding the uprights on, so I carefully dust bore the front and rear bushings on the mill. I only needed to remove a few thou to make them round again:
After welding on a 12" diameter by 1" thick face plate to the roughed out main shaft, I start to true everything up on the lathe. The holes in the plate allow me to bolt my engine block to the stand from the front (timing cover side), the back (bell housing side), and from the bottom with a special fixture I will be making (main caps side). I'm hoping this will help make it easier and more comfortable for me when I create/make my own accessory parts:
I then finished turning down the main shaft to fit the bushed headstock sleeve. I leave 2 thou clearance for the shaft/bushing interface so it fits nice into the headstock:
I check the headstock final fit to the main shaft before I remove it from the lathe. Perfect fit!:
I finish bore the rear of the main shaft for the 30:1 gearbox I found in a dumpster about 15 years ago. You can't go this far with an engine stand and not have a gearbox!:
And here you can see the headstock and uprights balancing on the base I built. I gave it a 1 degree rearward tip. I'm thinking of increasing this to 2 degrees:
Most of the stand is built from 3" square by 1/4" wall tubing. The angle holding the wheels is 4" by 4" by 1/2" thick sides. The other cross bits are 2" square by 1/8" wall tubing. Should be strong enough to hold a Hemi! HA!
I'll post up some picks of the final stand when I get it finished.
Take care all!

Nice job David! It'll look and work great when it's done! One question - do any of the casters have 'brakes' on them? If not, you might want to swap at least two of them out for a pair with wheels you can lock.
