I have a pice of 6" round x 3.5" mystery steel (probably 1018), and need a fixture to turn a crankshaft that I cannot turn between centers. I drew this up, but am looking for some feedback or other ideas before I start, as its a heck of a lot of metal to remove.
In use, the stock is clamped in the V notch of the sled, which is on dovetails, and adjustable with a 3/8 screw running the width of the tool. Not shown are the screw and the gib for the dovetail locking, never designed a gib before, anything to watch out for?
The backside has a bolt pattern and recess for a standard 4" minilathe mandrel, as well as 1.75-8 threads for my dividing head.
I doubt the idea is new or unique, so any similarity to anyones favorite tool or setup is probably because I read about it somewhere before. Let me hear your comments, tell me if I am missing anything, before I dull a bunch of tools with all this cutting.
