El Beast - Initial design phase, comments and critique welcomed!

Actually that's just the angle of the pics, I designed it with the idea of having the bottom of the spindle nut approximately 1cm below the bottom of the mounting plate for that very reason. Obviously it's fairly easy to adjust to taste simply by moving the spindle slightly lower/higher in the mount.

So I had a go at creating my first eccentric bushing this eve. Seems to have come out quite nicely given that I have no idea what I'm doing!

I started off with some hexagonal stainless steel stock, and installed my 4 jaw chuck on the lathe. First job was to turn down to a diameter I could measure off to calibrate the scales.



Then turned down to 11.99mm




I was designing it to the specs of a specific commercial product as before I got the lathe I was intending to buy them. So I had to copy the slightly odd offset of 1.07mm from centre:




Then drilled out the bore, flipped and faced the top side.




End result:
