Sorry cannot help but I have worked on one,the company where I served my apprenticeship had one of these Taylor mills,regularly used for instrument making so mainly light milling work,anyone who worked on this machine soon found out it was better to wind the handle and forget the power feed,not a very good arrangement.The other problem with the Taylor was their collets for holding the end mills,very difficult to do up tight,on tougher work the cutter would slip up or down in the collet,not a loved machine but the only alternative was a vertical mill with 4 ft table, thats how it was in the 1950s ,just get on with it.On a small machine power feed is not essential,and one got used to winding handles and using fixed stops,many of the jobs lasted a couple of days.
