Part 2 (of 3!) of the CNC router build. Hit a snag with the table that’s set me back a bit. CAD is coming once I get the table figured out and the model updated.

Surface grinders are great for making precise parts, but what if you don’t have one? It is quite possible to use a mill instead, even a small mill-drill like our “X3 super mill”.
The main problem with most mills is that the rpm will be too low to give a good surface speed at the face of the grinding stone. This can be overcome by using the highest speed on the mill (only once the stone is dressed and running true) and using a large dia. wheel. We inherited the one we have with a batch of other tools from eBay. It’s a Norton wheel, like these: https://ebay.us/WRcpHM
Friends, please be careful with second-hand (and even new) grinding stones – if they are not sound they can fly apart!
Also, beware the nasty dust, PPE is a must.

A customer had a worn-out aluminum bracket used to drive a crank arm off a motor. Using the Tormach PCNC 1100, the Tormach Personal Surface Grinder and Emco V13 lathe, we made a much stronger replacement bracket include a custom shoulder bolt to accommodate the fact that the bracket could not be expanded on the left hand side due to machine clearance!
A good example of balancing an improved design, pride of workmanship but also getting it done efficiently!
