Mounting cam-lock chuck on rotary table

[misshoran]

Hi
I have a Colchester 1600 Bantam lathe with a cam-lock chuck.
I have recently purchased a rotary table with a center locating plug
I would like an fixture to attach the chuck to the table.
The ideal tool I suppose would be the standard adaptor between
the lathe and the chuck on the lathe but I cant see a source of same.
Ideally a s/h one off a scrapped lathe one be perfect though I would
welcome other solutions.
Thank you for your interest

I went through the same problem a few years back. My solution was to get 6" x 3/4" disk of cast iron from one the suppliers. After skimming both sides the chuck was bolted on using the holes provide (I counter bored for the allen heads) and had holes to suit the 'T' slots on the table.

The problem with a lathe nose type fitting is you can't get the same amount of support to the edges of the chuck. There is a Myford nose/MT2 that could be used bit MT2 just won't be that stiff.

Hi Iv'e got the same problem as I have a Harrison M250 with D3
Iv'e also looked for a scrap spindle nose but with no avail.
If I could get a drawing then I would have a go at making one.
If I do then I will keep in touch, if you manage to find a solution please email me
Regards

For a camlock nose drawing, go to

BTW. The taper is 1:8

Thanks for the link but it was not so much the mounting angles I needed but the locking mechanism.
Perhaps I'll give Harrisons a call and see if they can help.

If you get the drawings and decide to make one, an excellent, inexpensive source for a cast-iron disk is a shop that carries weights for barbells.

Hi,

A partial reply can be found at

www.rohmgb.co.uk/uploads/tx_userproducts/KFD-HS_01.pdf

at page 36 are section of the Camlock spindle nose. The locking
device for the Camlock bolt is eccentric and probably of reduced
diameter at the locking section.
