View Full Version : Quillmaster QRA Disassembly?

Does anyone (John? :)) know how to disassemble the Quillmaster QRA, or have a parts diagram?

I bought a QRA from a member here, and there's a chunk taken out of the spindle nose (looks like it got caught on something). The spindle piece (the part with the setscrew) looks like a relatively simple lathe job (or possibly, a TIG repair), but I'm not exactly sure how the spindle comes out.

There's a circlip on the rear bearing that you can see in the picture above (from Tony's page). But the big question is, which side is the bevel gear facing? Is the bevel gear on the front, or on the rear?

If the bevel gear is on the front towards the spindle nose, can I just push the whole spindle out with an arbor press?

Thanks!

Robert

Hi lazlo.

I didn't even know what it was or what it did.

They sure are asking serious money for them on eBay.

"Googled" it:
http://www.google.com.au/search?hl=en&q=quillmaster+qra&btnG=Google+Search&meta=

First item was you on PM re. that item.

Checked bit further an realised that it is a colleted varialbe-angle compound angle drive fitted the the BP quill - the principal not unlike the end of a "Schaublin" mill.

Is this any help? Haven't checked too much at all.

Hope it helps.

Old Tiffie,

The QRA attachment is not the Quillmaster, it is the tiny little right angle option that fits on the end. The Quillmaster can be used without it.

My guess is that most of them are like mine - unused.

Sorry, just looked thru but only got pics of it, no exploded views and never had one to pieces.

Joel, Tiffie -- thanks for the bump and the rec.metalworking post! :)

Want to sell yours Peter? :)

Sir John has (had?) some neat pictures on his web site where he was milling keyways with it. That's where the QRA's shine: milling internal groves or slots.

John, thanks for the reply -- I figured if anyone had taken one apart, it'd be you.

Someone on PM pointed out that I should be able to tell which way the bevel gear was facing by the way the two perpendicular shafts rotated with respect to each other. If you drive the top shaft (that connect to the Quillmaster) clockwise, the spindle (which holds the endmill) goes counterclockwise. So I'm hoping that means that the lower bevel gear is on the same side as the spindle nose, so I should be able to just push the shaft out.

Thanks again guys!

Cheers,

Robert
