Are you working on 240 or 415 volts?

You could always turn a 3MT down to 2MT.

Much as I hate to disagree with Hopper, I have a book entitled "Machine Construction & Drawing" with examination papers going back to 1888, 1889 & 1890 clearly showing the thin nut under the standard nut.

Hello Celso, you've made a great job of that, it looks really good.

I suspect that is because the thin nut should go on first.

It looks as though the end of the thread has been hammered over to prevent removal.

Thread: Amplifier Repairs..
03/12/2019 13:26:55

Looks to be nicely made.

In another life, in another age, I was a DJ and knew a member of a Nottingham band who worked at Carlsbro who made amplifies. He made me several 400 amp amplifiers over a period and even went to the trouble of hand winding coils with exactly the correct number of turns. They were wonderful amps and the mention of EL84's made me remember.

The then bass guitarist from Status Quo was particularly impressed with a 400 watt amp driving a set of 18 inch Goodmans speakers, I had to make sure they were loaded into the correct van after a gig.

Thread: More evidence that the world has gone mad!
03/12/2019 08:25:56

I tried to leave good feedback for a tub of protective wax bought through Ebay by saying "Endorsement by the British Museum is good enough for me"

This was rejected by Ebay on the grounds that swearing is not allowed!

It turned out that the offending word was 'endorSEMENt.

Another possibility is the SPEETOG PLIER CLAMP.

I don't know if they are still made but there seems to be some available on the various auction sites etc.

Thread: VFD off the bay
28/11/2019 22:25:24

I think we should remind ourselves what the original question was;

" Looking on the bay there are literally loads of far eastern drives. Has anybody got one of these versions in service ? Are they reliable ?"

I think that has been well and truly answered.

Thread: what material
27/11/2019 20:30:14

Hello Kevin, you are in a club then ask the boiler inspector or see if someone has the drawing with the information on it. As there are only 2 stays I'm assuming that these are longitudinal stays. Are they threaded or silver soldered in? Material is most likely to be phosphor bronze but may also be copper but check before you do anything.

Thread: New here but into clocks
27/11/2019 10:58:30

Welcome Derek; as Roy says, all are welcome and free to ask questions, or answer them.

I cannot claim to be a clockmaker 'though I have made one and have repaired several.

Thread: VFD off the bay
26/11/2019 12:39:41

I bought one recently direct from China. Apart from the good price, it was the only one that I could see that had a removable keypad with a 1,5 mtr. extension so that the keypad could be placed close to the operator whilst the main unit remained safe away from flying swarf.

The unit I chose was a 1.5 kw or 2hp to power my TS Major.

The instructions were simple; 6 wires to connect, 1 for earth, 2 for live and neutral and 3 for the connection to the motor once swapped from star to delta.

The unit came with a variable speed control which I didn't think I would use but it has proved useful for running in the new motor and spindle bearings.

Cost; just £43 inc post. Like this one: https://www.ebay.co.uk/itm/1-5KW-2HP-220V-Single-To-3-Phase-Variable-Frequency-Drive-Inverter-CNC-VFD-VSD/202773455849?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m2749.l2649

Thread: Royal Mail tracking
26/11/2019 10:18:50

I've just taken delivery of a coolant delivery pipe for my TS Major. The delivery record shows that it is still at London airport!

It was delivered from China to London overnight and it has taken Royal Mail 5 days to get it from London to Mansfield.

Thread: Knurling tool operation
22/11/2019 19:42:04

I find that you need a slow speed on the lathe such as lowest backgear and, if you can, flood with coolant to wash away any chips that would otherwise be crushed back into the knurl.

Thread: Mitutoyo DRO Fault
19/11/2019 15:31:48

Sent a message to M-DRO. I have one of their units on another machine and am very leased with it, otherwise, It's back to modelling because I'm fed up with fiddling!

Thanks to all who tried to help.

Brian

Thanks for that Nick I may well give them a call, but first I,m going the check the wires in the armoured cables as I know some of the plastic in other parts of the machine are stiff and brittle and I thought that the problem might lie with broken wires and it's any easy check to make.

I'm in no hurry and I'm not even sure how useful a DRO is on a horizontal mill. ( plus, I'm a miser)

Ah well, all this swapping of plugs and amplifiers has resulted in the one that WAS working, now isn't!

Brian

That really clarifies things.

The 'one' what?

Ian P

I thought that it was obvious; the display that was working now isn't. In other words both displays do not move when handles are turned.
