The Plate with all the holes in it is just an aluminum plate with a bunch of holes in it
They are tap drilled for 1/4-20....when I need a hole threaded, I just tap it.....I'm lazy.
It was intended to be sacraficial, but I try not to cut that one....it's handy.
The face plate is 10" diameter and has a 2 1/4-8 spindle nose so the gapping hole at the center makes mounting smallish work problematic. I just mount this little plate on the big face plate for convienence. I have a fist full of small straps and such that help out here.
There happens to be a 1/4-20 hole darn near perfectly centered with respect to the lathe center....which is also convienent.
The non drilled plate is a piece of jig plate from the scrap box. I bored it for a close fit with the crankcase bore using a bushing to create a male spigot on the plate. Now I can mount the fixture where ever I want on the faceplate or mill and have at it, and it won't move around much. I'll hang on to these fixtures until I'm done...then back into the lucky box they go!
These fixture plates are just that.plates..normally I square them up, the second one I didn't, though I may still. They make it easy to float around the machines with different set ups and be able to pick up the work again, especially with a mill vice, and they're simple things to make and use.
That set up took a bit of reading and noodling so that all that could be done in one setting on the lathe ( cover, gear case and block all bored at the same set up to maintain concentricity. ) I wish I could say I thought of it but I think ETW's writtings speak of this set up in many places....its just adapted to my lathe and tooling.
I like faceplate set ups as they are very versitle and quite ridgid once set......though I may be in the minority there.
Bob, I think it will be .....My kids are excited...which is the point of this exercise...My son really likes diesels....this is as close as I think "I" can make....
