What about this one
http://www.arceurotrade.co.uk/Catalo...-Collet-Chucks
Part way down the page, ER 16 on a 20mm parallel shank.
ER16's are good to 10mm
I suspect you have found out but they close a full mm so they will hold any size.
6 to 7mm will hold 6mm and 1/4", 3 to 3.5 will hold 3mm or 1/8" and 9 to 10 will hold 3/8" and 10mm so you only need about 4 collets to hold eith standard sized cutters.John S -

Yes, John, That's the one Jeremy used in his spindle design. Must confess I didn't notice the 1mm range in compression. After all, we were told as apprentices "that to be an electrician you need to be able to read or write, not necessarily both!"
I've now got a MSc in Electronics but keep that quiet :heehee:
I was thinking along the line of the smaller shaft for ease of coupling to the DCBM, but looking at the spec for them I see they feature a 4 or 5mm shaft. So a bit of lathe work is needed whatever way.

I am watching this thread with great interest because building my own spindle and interfacing it with mach is something that I also would like to do.
The mechanics will not be a problem for me but designing electronic boards and putting them together has never been one of my strong points!
What I do have though is a selection of various good quality DC motor speed controllers that may be of use and would be happy to send one to you if it will help. Let me know the spec of the motor and I will see if I have anything that will be any good to you.

I don't need one "of YOUR damn DC speed controllers".
I can make my own!Templecorran

Smart arse.......
But seriously, if you do want one they are four quadrant, digital speed controllers, switchable between 24-36v 200A max, speed control accepts 0-5v or 0-5ohm, forward and reverse, fully programmable acceleration and decel. All parameters changed by using 3 buttons on the front. Lots of either features that I won't go into. If you want a manual then I can email you one so you can have a look to see if there any good to you.
As long as you point me in the right direction for when I do my spindle electronics then you can have one for nothing.
And before John says anything, yes they are mine!Last edited by HiltonSteve; 11-08-2009 at 04:44 PM.
