Fellow tin hip users - this helps me daily:

People, generally of the male persuasion, who, in "solidarity" with prisoners in the USA have decided to let us all share the view of their underwear.

The Telephone Preference Service (http://www.tpsonline.org.uk/tps/index.html) has reduced the nuisance calls I receive at home to a trickle.

It is free to register your numbers.

"It is a legal requirement that all organisations (including charities, voluntary organisations and political parties) do not make such calls to numbers registered on the TPS unless they have your consent to do so".

Further to the above, would anyone like to old Nordac to play with as a repair project or just a a source of parts?

I will happily post it (mainland UK) with my compliments.

Preference given to the folks who helped me through the issue.

Delighted to report that my VM30 mill is up and running again with a new Invertek inverter. The change went smoothly once I got over my electronophobia.

I have decided to take the advice on board and use the inverter functions for speed control and thus far it goes well.

Many thanks again to those who helped.

Charles

Ian,

The mill used its original controls so I had mechanical control of speed and never considered using the electronics in their place.

The inverter was inconveniently remote mounted so using functions was not ergonomic (translate: big lad, small workshop, too many belly bruises from corner of table).

The new inverter will be mounted on the belt guard so will be convenient to use.

But I will probably continue to use the mechanical controls for speed.

Neil,

Aye, there's the rub!

Of course I switched off wrongly as well.

I am, at least, consistent.

Charles

The consensus is that I have fried the inverter over time by incorrect starting technique.

A new item has been ordered.

May I thank all who offered help and advice, with special thanks to John Rudd who advised off-forum.

Onward and upward - but select the motor "on" first!

Charles

Graeme,

Thank you - I think I understand.

Are you saying I should have been setting the motor switch "on" before firing up the inverter?

Oops! The capacitor is in circuit with the coolant pump.

Sorry for the red herring.

Graeme, the inverter gets switched on at the 13A wall socket, then the motor is switched on using the original Boxford switch on the machine panel.

Thank you John.

My inverter seems to be an earlier variant. There are only 3 buttons on the panel,  P, + and -.

I have the manual and can work through the parameters but that's about my limit.

The motor is 3 phase and a large capacitor is included in the wiring.

I was happily making chips on my Boxford VM30 yesterday, took a short break, came back and the mill would no longer run.

The machine has worked happily with the inverter (Nordac Compact) for about 12 years so this has come as an unwelcome surprise.

The inverter is electrically live and the parameters are accessible from the simple buttons on the panel. The parameters are unchanged from when it was running OK.

Now when I switch on, the inverter panel displays 036.8 (no "F" so not a fault code?) and the 8 flickers on and off.

I am electronically a dimwit.

Can anyone offer advice?

Hello all.

I have done my usual and over-researched and over-thought this.

Please help me decide which DRO to buy!

I'm mainly looking for ease of installation.

Thanks for any thoughts.

Charles

It's a pedant attractor.

Here in Wem we have jackdaws.

There is folklore that a dear, sweet old lady released a breeding pair 50 years back

All I can say is that, in clearing the 6 flues in our 1860 house (blocked in 1960/70 "improvements" I removed 26 wheelbarrow loads of nesting and other detritus.

Don't like jackdaws!

Plasma cutter?

I recently cut 9" holes in 18g stainless with my handheld plasma. A tapered hole was cut in a wooden batten to accommodate the cutter head and a screw was inserted at t'other end to provide a pivot.

The cuts took less than a minute each.

Having worn one a time or two, I think foolscap (13.5x8,5 inches) is just the right size to form a Dunces' cap.

SillyOldDuffer - "the thing had stopped working after a series of improvements" - is that the same as "it was working, so we fixed it"?
