Slight update, it sprang to mind that i already have a VFD running my lathe, it's only 2.2 kw so wouldn't be any good for real work as the mill motor is 2.2 kw, but i figured it should run the spindle quite easily with no load.

Wired it up and ran the mill, to discover to my embarrassment that the back gear was engaged (engagement lever works opposite way to what i thought) hence the rattle when running from my undersized rotary converter yesterday.

Knocked her out of back gear and the head is virtually silent throughout the high range......result I thought it was weird, as i heard the mill running on true 3 phase when i bought it, and never noticed any undue noise, although the machine was outside at the time.

I'm now shopping for a 4kw inverter to run the spindle motor, and a titchy one to power the 1/3hp table feed motor.

Thanks for all the replies, much appreciated.

Considering the knurls were probably done by a Six year old using 100 year old equipment, working 80 hrs a week for Ten bob a month, i reckon we ought to cut him some slack......

The reason for my original question was the VS head on my Beaver is a bit rattly, so I'm weighing up if it would be worth doing away with the VS gubbins, and making it a direct belt drive running from a VFD. It still has a backgear, so i would still have high/low ratios to play with.

The other alternative is to strip and rebuild it, however unlike Bridgeports i doubt spares will be available at any cost. Thoughts on a postcard please.

A question for those running milling machine spindles from a VFD, do you tend to leave the mill in one gear/ belt position, and use the VFD to control speed, or do you find it necessary to still swap belts/gears for certain jobs.

Do you have any large mates ?

Hi Mark

Much as it might make you feel better, I would advise against naming and shaming on a public forum. It won't change anything, and might actually work against you in the long run.

I've used the small claims court on three occasions, it was quick, cheap and painless ( all done online) and each time I got paid as soon as the court papers were received by the non payer. Most people don't want the hassle of going to court or being landed with a CCJ.

Of course there is a chance you might still not get paid, but you will only be £30 or so worse off than you are now, and the non payer will be blighted with a CCJ.

Did the lad building the engine fit a circlip to the gudgeon pin ?

i watched that bit 3 times, and if he did it wasn't half slick, maybe he was a conjuror in his spare time

Have you seen this Rob ?

Ah yes, the Suprima, You're correct, common issue, have changed loads of those, latest pcb comes with a full new wiring harness, so is a pain to change.

Ideal Isar by any chance ?.....

Wow, it made £1800.

Strong money indeed, although small mills do seem to make high prices.

That's a shame, plenty more fish in the sea though Rob........large turrets are not exactly thin on the ground.

Did you buy it Rob ?, still being advertised, but with a slight price increase

Ok Andy, I get the impression I'm flogging a dead horse, but I'm going to offer one more little beauty, before I shut up for ever ...........

You think you've got problems Chris.....

I read that heading as 'Savage aggressive big Flies'.

Thought your workshop had been invaded by monster insects.

Why do you think a second hand machine would necessarily need fixing, both the Boxford and Tom Senior were both solid well made machines, designed to withstand light industrial use and last a long time. It sounds likely that a lot of the new chinese machines will need more 'fixing' straight out of the box. Your budget would buy a lot more by going secondhand and get you a more versatile future proof machine with a strong resale value.

Neither are stupidly heavy, even a Bridgeport could be moved with an engine crane. I'd side with your Father in law, because I can guarantee that's probably where you will end up eventually............

Ha Ha, wish this forum had a 'like' button

You will probably have to host it somewhere like youtube and then provide a link.

would be interesting to hear the noise.
