I am working on making a collet chuck for my lathe. I've got a backplate machined to fit the spindle which I plan on attaching a piece of stock from which I will machine the collet threads, tapers and recesses.
I was figuring on boring the backplate and turning a matching diameter on the collet holder piece which I will press into place and then either silver solder or TIG weld before machining the combined part into the final dimensions while mounted on the lathe.
My question is which would be better: TIG welding the parts together, or silver soldering. I have everything I need to do either, but I need a rundown of the merits and drawbacks of each, and what type of fit/clearance I need between the parts.
I'm assuming if I'm going to TIG it, I'd want to bevel the parts to allow better penetration. Do I need to be concerned about stress cracking or preheating? What kind of clearance do I need on the fit between the parts?
Both pieces are 1018 steel. The backplate is 4" diameter x .75 thick. The "chuck" part is about 1.675" diameter x 2.5" long.
This is a one off project for my own use. The time is mine and I do this for fun, so my preference is to spend more time and less money.
