True but thread gauges are more to do with matching the pitch. Although Whitworth and Unified course have for some diameters the same pitch it is not true for say 1/2" Whit 1/"2 UNC . which are 12 TPI and 13 TPI respectively. If you buy a Whit thread gauge set it most likely that it won't have...

[url=http://www.boconline.co.uk/en/products-and-supply/industrial-gases/shielding-gases/argoshield/argoshield.html}argoshield explained[/url] Maybe my explanation was a bit simplistic. Argon produces a much better ionised gas which carries the arc. Argoshield contains oxygen as part of the...

After welding, stainless should always be pickled to return the surface of the welded area to a corrosion resistant state. as here It is never recommended to leave stainless as welded without this or similar treatment

Why not a Gassless/ non gas set such as This Best of both worlds. By being able to reverse the polarity of the Torch, one machine will change from Gasless to Gas operation. Mind you I am spoiled running two Industrial Migs (one with spool on gun) on industrial sized bottles, 250A Tig water...

There is absolutely no problem obtaining spares for Colchester lathes. The Student has a 40mm bore spindle, the Chipmaster 35mm. Bantam 2000 is 32mm . Colt is 35mm . Myfords only sell because it is what model engineers use , and what model engineers buy. They buy them as a result of Myford...

I have a Mascot 1600 at work and a Mastiff 1400 with DRO in my home workshop. I like Colchester lathes. I also have a Kerry 1340 for smaller stuff.

My only thought was a Teknatool chuck insert is about £20.00 and is CNC manufactured in big runs. If a company can hand make a one off for half the price, they either have to be very very quick at what they do if they can make a sleeve for £10, or they are working at a very low hourly rate...

Colchester student, chipmaster or Bantam?

Where abouts in Lincolnshire are you and which company did you use?

M33 is 65% increase in thread size over M20. I have my doubts there will be enough metal to take this thread which Is why I suggested using a backplate. Most engineering Firms charge £30 per hour or thereabouts. I think you got a very good price few other companies would care to match. £10...

we meet again!

I am a bit confused since Multico is listed as M20 x 1.5mm Not M20 x 2.0mm M20 x 2.0mm is normal for Tyme Cub or Gem.

Axminster still list iso backplates......They are used on their super precision chuck

Is the chuck on a backplate? One option would be to buy a standard ISO backplate in M33 x 3.5 and the machine the back of the chuck to matching register and to fix the chuck to the Back Plate with Allen Cap head screws. Unless you strip the chuck you will not know how far you can bore out the...
