Did you notice the draw bar? It uses the collet stop internal threads.

Yes. And that the collet holder registers on a groove in the draw bar.
 
2.250 diameter X 11.5 freecutting 1215 Steel just arrived. This is for the Wheel Spindle Housing. We are on a roll today. :lmao::lmao:

It will take a lot of machining to do this part in CRS. but it is do-able. There are also 3 or 4 changes I need to incorporate to make everything work. As said before, this is what wood is for.

Good thinking, first making proper scale drawings, then mocking it up, in wood.
 
Two things need to happen before any metal is cut.

#1 -- The bottom shaft binder hole needs relocation to facilitate the "Index Pin" It must be moved to the bottom of the shaft hole from the top.

#2 -- To make #1 happen the part must be made .375 longer.

This would have been disaster if it weren't found out now.

With some fine tuning this will work. That's it for the mock up. Ready to go.

Yup. It was a good idea to mock it up.

The layman would likely be bewildered to learn the amount of effort that goes into developing a one-off of this precision and complexity, regardless of having begun with some excellent resources and having had the time to work out, in your head, much of the design. Including some fair amount for (engineering, fabrication, assembly, testing...) time, plus parts and materials, the end result will represent a substantial investment. Besides ultimately having a working grinder you can be proud to use, your ROI is the many lessons learned, the knowledge shared and satisfaction of a job well done. But also savoring the entire process and making that richer by including interested others, here.

Billy--attaboy!
 
Thank you Andy. The kind words are greatly appreciated.
