Hi, this is my first post here but i have been reading others helpful post on here for quite a while. I picked up a Holke F-11-v knee mill several months ago and have been cleaning it up and using it and ive got a few questions i hope someone can help me with. First, does anyone know if this machine is somewhat compatible with a Lagun ftv-2, alot of the castings and parts look similar and i know they are both spanish machines. Second, I get some noise from the belt drive when i slow in down past approx. 1000 rpm in high and the equivalent belt position in low range. It seems like it has something to do with the rear pulley. Also, does anyone have access to a manual for this machine? Thanks for any and all help.
