Just lowered the speed of my HF   Topic List   < Prev Topic  |  Next Topic >

Re: Just lowered the speed of my HF

The current/torque control, keeps the fuse from blowing when started
at speed and when stalled.
If it's wrong the other way lathe will have no torque.

The compensation pot control keeps the RPM steady as the load changes.
If it is adjusted wrong the lathe will slow under load or it will hunt.
The speed control and the current control are interlinked so each has
an effect on the other.
I have mine adjusted so that it will do zero RPM.

I got one of the Red HF 7x10 Lathes about 4 months ago and just got around to using it and found that the lathe speed was too high for me to thread easily on...

The HF lathe controls are made by XINYU of China. If you lower the low speed, it drops the top speed proportionally lower. Shane ... about ... should be able ...

I had found 3 pots. One was marked on the diagram "Speed", and that's what I used to lower the speed, just like everyone else. The middle one did what...

The first pot is the speed control, the second is the pulse by pulse current limit/torque and the third is the speed compensation pot. Shane ... that's what I...

Thanks Shane, I think later this week I'll mess around with the compensation pot to see if I can improve anything, but I suspect that maybe the factory setting...
