A few months ago I purchased a small yet to be identified horizontal mill https://www.practicalmachinist.com/.../small-old-horizontal-milling-machine-378617/. It appear to be similar to a larger Cincinnati that is in another thread on this forum.
I have a question on spindle rpms. Are these spindle speeds in the correct range? It currently has a 2" pulley on the motor. If I use a 1 1/2" drive pulley I can reduce the rpm's by 25%.
1-216 rpm
2-352 rpm
3-572 rpm
With the back gear engaged.
1-40 rpm
2-65 rpm
3-105 rpm
Thanks, Justin
