Re: Which Bronze to use ?

In any case, the only way you'll know if you succeeded is after you've made the nut and disassembled the lathe to test its fit on the shaft. Given this, something to think about is buying a tap that would give the tightest fit (i.e. having the class of fit giving the smallest ID), making the nut, d...

Re: Which Bronze to use ?

I recently had this problem with my '48 colchester master lathe. Ooooh nice ! I'm currently looking at Colchester Triumph lathes - 50" between centres - as I'm becoming more & more disillusioned with my Chinese 'Warco 280VF'. Can I justify such a thing after spending all that money on the ...

Re: Which Bronze to use ?

I have 1/2" x 10 TPI ACME 29 taps & dies in both Left & Right hand but I'm reluctant to use them for the reasons you state. They are a bit of a blunt instrument. I have also got "Indexable" carbide tips for internal 10 & 8 TPI but they are quite substantial and the boring ...

Which Bronze to use ?

A quick one for you Metallurgists out there . . . I'm finally getting around to re-furbishing my 1950s Denford Viceroy Lathe. The main problem is slack in the Cross-Slide and Top-Slide nuts. The 'nuts' are tubular pieces of bronze bored with a 1/2 inch 10 TPI British ACME Thread (29 degree cutting a...

Re: Lathe user?

Pictures from "BertieB" . . . The spindle fits 8-) . Something doesn't look quite right though and the spacers need 'adjusting' to bring everything into line. The speedometer drive hasn't been fitted either. Hopefully the offside frame rail will spread out to allow everything to be accommo...

Re: Lathe user?

Well, I haven't heard from 'BertieB' for a while - I think he's on holiday - or else he's gone to ground ! Progress (YEAH !) the shaft is ready, but as I have no idea what his real name is, or where he lives I can't post it to him. Hopefully he'll be answering my PMs soon. 'Bertie' sent me the spind...

Re: 1948 Iron 4G Coil Ignition

It does sound like fuel starvation. 1. Does fuel run cleanly from the fuel tap in the tank (no clogged filters in the tank) ?? 2. Its a very long time since I had a Solex carb, but: If you remove the float bowl while its connected to the fuel tank - does fuel run cleanly from the needle jet - and do...

Re: French Parrot

There are some very interesting bikes there and some beautiful examples of those familiar to us Brits.

Interesting to see the new BMW R18 in the flesh - an 1,800cc boxer cruiser motor that is appearing in all sorts of weird 'cruiser' configurations (if you read the Bike Press).

Re: 1948 Iron 4G Coil Ignition

....and always use a new one one,not NOS. Yes . . . But . . I restored a Series III Landrover with the 2286cc petrol engine. I renewed everything but it wouldn't run. I took the new condenser out and put the old one back in - Bingo ! Beware pattern parts badged as Lucas ;) . Sometimes it pays to ha...
