I have a HF 7X14 lathe that I would like to get a little more performance out of. I have read many threads, here and elsewhere, about motor changes; gear reduction systems; etc. I believe that my machine has the 250W motor and the motor control board FC250. Will upgrading to a KBLC, KBIC motor cont. bd. give me some additional performance from the existing motor?If yes, is there a difference between the two KB boards and do I need the PECO speed controller add-on bd. Thanks for any help you can shed on this subject.
