what is it 2

Following Nicks post I have an items I purchased a few years ago but I dont know where from or what its called. I use it for removing bearings from RC engines.

The way it works is the tapered pin expands and forces the outer (which is split and can expand a little) to grab whatever it is inside .

That's very similar to a expanding arbor for lathe work, used for holding a cylinder you want to turn the whole od, but they have a parallel shank.

I found where I purchased it. lol http://www.ebay.co.uk/itm/RDGTOOLS-...Home_Garden_PowerTools_SM&hash=item51a3b0906b

Still not sure how the one I have is supposed to be used but I will be doing a bit more research now as its intriguing me.

Made this handle, which works on the same principle for my Myford ML7 (fits in chuck bearing shaft). I use it to manually turn the chuck when I want to thread the work piece using a die box or tap in the tailstock. It allows you to put pressure on via the tailstock whilst turning the chuck to get the threading to start easier.
