Hello!:wave:


I've been watching this forum for about a year now and last November got myself Optimum BF20L. First did some parts for my RC models and then started CNC conversion. Now I have got almost everything to complete the mechanical part, just waiting for the bearings since the end of December and also need to buy the necessary screws/shims etc. This week I plan to order the electronics.

My plans are:
* enclosure, because the chips all over the garage are killing me
* belt conversion
* 4th axis would be nice to have

Now on to the pictures:

Making of the parts


As everything is now (ballscrews have 0.1265 balls)



One question:
The oldham couplers I got don't grip the ballscrew ends very well, so I thought that I should drill and tap holes for setscrews, is it good or bad idea?




I'm a high school student so be easy on me, I don't get all the engineering things at first


Cheers,
Mart
