Good news - we're open for limited services in Wembley. Ujima House is now actively under refurbishment and we'd love your help in making the space the best it can be.
During this interim period donations and continued membership are greatly appreciated while we transition to our new space.
Works, but is not very precise!
9 Aug 2013 - sjrapid and will took the arbour and chuck off, and tested the quill run out with a dial indicator.
Quill runout is approximately 0.2mm (should be <=0.02mm, 1thou) ). Runout at the chuck can be anything up to 10x this depending on selected speed and cutting bit. Your holes may be oval!
Here's the dial-indicator test video:
There is a pledge running to get a new Drill Press for the space.
The space has an Axminster drill press. The keyless chuck only goes down to 2.7 mm, so for anything smaller you need a "pin chuck".
Or you can use the Dremel and mini-mill for high speed / light duty / precision stuff. Ideal jobs :
- High speed, tiny bits e.g. PCB drilling
- Milling plastic, small aluminium etc.
- Drilling jobs requiring accurate positioning - use the table positioning
- Most general purpose drilling jobs
- <lovelace_> The chuck for the new stand drill falls out easily
- <lovelace_> I can't see how it tightens up
- <artag> it should be a taper. Assuming it's clean (not got anticorrosion varnish on it) then it should want a good fast whack up into the quill. Not with a hammer - just push it fast, by hand. Use the momentmum of the chuck to get it in hard.
- <artag> if there's a screw thread in the end of the taper thrn it can use a drawbar like the 3-in-1 but that's fairly unlikely
- <lovelace_> K, seems firmly in now
- 9 Aug 2013 - sjrapid and will took the arbour and chuck off, and tested the quill run out under no load with a dial indicator. Also tested with a new certified chuck and arbour (0.0012 TIR). Measured run out of about 0.25mm on the new chuck. TIR not measured on the existing keyless chuck.
