Thread: Lathe chuck
02/01/2018 20:04:10

Most 4 jaw independent chuck backplates are smaller than the body diameter. With 3 jaw chucks, the backplate is (usually) the same size as the diameter. Check the specs of the chuck you intend to buy, will tell you what size you need.

I believe Chronos stock suitable backplates.

I'm sure there were plans for a 'Napoleon' with field carriage and limber in one of the Home Shop Machinist Project books.

It sounds like a neon indicator, they do this if there is some leakage current.

George, the bearings on my MK1 feedbox were not on the feedscrew, they were on a sleeve which joined the feedscrew to the feedscrew extension.

Thread: DRO- only one set

Definitely the mill! I fitted a 2 way to my mill, PCD, calculator and many other functions, it was very good indeed but I regretted not going for the 3 ways.

Welcome Danny. My first car was a 1949 side-valve Ford E493A Prefect coupe utility bought in 1972 for AU$120. These were unique to Australia i believe, with a locally built style-side rear grafted to the front half of a standard saloon body. Was a great little car, but needed more work to keep it going than i was able to commit so I sold it about 20 years ago. Mechanically pretty indestructible, but the timber-framed body was only held together by the paint. Geoff in Brisbane Australia.

Our Morris Minor 'Woodies' have the same problem, the wood parts are still available but it's a big job!

Thread: Which spindle fitting on my milling machine?
15/12/2017 13:55:28

It sounds similar to my Denbigh milling machine, the MT4 spindle nose is just visible on the lower right of the picture. Most of the tooling I have has the rectangular collar.006.jpg

Thread: Evading VAT and Import Duty

VAT is a EU tax, when the UK has left the EU it should no longer apply to UK citizens. Niko.

It may not but don't look for a saving, tax is a bit like death, difficult to avoid.

Thread: Myford Bed Regrind
06/12/2017 20:22:09

I don't see why it should affect rigidity of the machine, that's the way Myford did it.

Thread: CFH Gas & Welding device kit SF 3100
29/11/2017 14:24:26

Are there any air blown torches suitable for use with Propane? A long time ago I used a purpose made torch with coal gas and the blow end of a domestic vacuum cleaner for brazing, very hot it was too!

Posted by derek hall 1 on 23/11/2017 16:11:41:This goes to the heart of the restoration debate....what is left of the original parts fitted to the Flying Scotsman for example?. It must have had new boilers, wheel treads, bearings etc during its life so what bits left are the original bits?...
Reminded me of grandads hammer, 5 new handles, 6 new heads.

Thread: Gearing Myford S7
22/11/2017 23:16:01

There are two versions of the Myford Series 7 gearbox, one for the UK and one for the USA (for Unified thread pitches, the text on the ratio label is blue.

Metric Myford lathes have Metric feedscrews. All Myford Series 7 leadscrews and gearboxes were Imperial.

Cutting Metric threads on these requires either the Metric conversion set or two or three non-standard gears which allow reasonable approximations.

Thread: What is it?
19/11/2017 14:46:50

The bakelite knob appears to be a later addition, planers were usually fitted with a capstan wheel. Small planers became obsolete many years ago, I've seen a few over the years, most dating from the 19th or early 20th century. Fairly common at one time, they are probably rare now because most of them went to the scrapyard.

Michael, a number of my ancestors were brass finishers, mainly in the Birmingham area.
