Cross slide improvement for a 9 X 20 lathe

Hi Andrew, your reasons for buying a used 9 x 20 are your own affair....its good to hear why in this case, helping someone out....kudos to you.....As I said in my earlier post, horses for courses....in fact given the drawbacks of the 9 x 20, I went on to buy a bigger and 'better' machine, very similar in spec to the Warco 290.....between the Chester and the 290 clone, different as chalk n cheese...

.its all down to cost...the Chester was around £700 when I bought mine some 10 yrs back, the clone 290 was just over £1700 delivered with a stand and the usual extras...added to that a 3 ph conversion brough the price to under £2000....

Hope your deal goes through and you enjoy modding the machine as I have mine..,

Back again re the Huangyang VFDs, one came from Leicester and others from Germany, we thought they were coming from PRC in three weeks time. The first took three days from Leicester the UK supplier and the others took three days from Germany, all appeared to be packed by the same people. John

I've had two HY inverters.

The first was a 1.5kw model that I fitted to my Chester Eagle 30 mill, which had its 1ph motor swapped for a 1.1kw 3ph model of the same frame size (90  . I sold the machine on after having used it for several years...

The second inverter was the 2.2 kw version, bought in error, it was originally going to be a spare for the mill...I gave that one to my bezzie mate for his Chester mill....

The quality of theses inverters appears to be no worse than any of the European made inverters ( Siemens/ABB ) that have come my way...suffice to say, I'm not an expert.....

The pcb assemblies appear to be well made, due consideration being given to areas carrying high votages and high currents. Some form of coating is present on the board surface to prevent moisture ingress....

The main thing that lets these inverters down is the manual!
