|Thread: Lathe chuck|
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.
|Thread: Napolionic cannon|
I'm sure there were plans for a 'Napoleon' with field carriage and limber in one of the Home Shop Machinist Project books.
|Thread: Sad but true!|
|Thread: Central heating query|
It sounds like a neon indicator, they do this if there is some leakage current.
|Thread: Thread, counter error?|
|Thread: Magazine wrapper|
Grey plastic bag.
Sometimes you get 2 magazines, pity they are both the same.
|Thread: Thread, counter error?|
Just viewed some of my posts, I noticed the post counter (number of posts) seems to be stuck.
|Thread: Bridgeport Series 1 Mill Feed Box|
Does anyone have instructions for use of the Bridgeport Cherrying attachment please.
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.
|Thread: Hello Everyone|
|Thread: Which spindle fitting on my milling machine?|
|Thread: Evading VAT and Import Duty|
|Thread: Myford Bed Regrind|
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|
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!

|Thread: Gearing Myford S7|
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?|
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.
|Thread: What Did You Do Today (2017)|
Michael, a number of my ancestors were brass finishers, mainly in the Birmingham area.
