EasiTurn Chuck/camlock type?

[SimonRafferty]

I want to buy a new chuck for my Easiturn lathe.

Do you know what type of cam-lock back plate fits? Are they the same as one of the other more common brands E.g. Colchester?

Thanks in advance,

Si

Simon,

Should be a standard D1-3 - the same as on the manual 280 VS and Synchro machines.
Also the same as a Colchester Bantam, Harrison M250, etc., but not the larger machines (Student, M300,etc) which are D1-4.

If buying used, make sure you check the size, as things are often incorrectly identified. The dimensions (pin dia , PCD and taper) are easily found via google.

Hope this helps.

Just thought - don't mean to teach you to 'suck eggs' - but are you aware of the adjustment that camlock pins sometimes need to enable them to be locked properly?

Let me know if you need more explanation.

Thanks for the help.

It's not that the chuck I have is broken or does not fit - it's just very small - 100mm across. I'd like 160 to 200mm across plus a 4 jaw.

Just wanted to order the right back plate first time!

Cheers,

Si
