View Full Version : What to do with a tiny XY table?

It is not really an XY table, it is a Sherline mini lathe without headstock or motor..

.... I got it because I need the tail stock for another Sherline I have with a damaged tailstock.

So what to do with the bed and cross slide?

P.S. These are the original, genuine, made in Australia brass Sherline lathes.

I put one on the table of one of my radial arm saws and use it for a grinder - or what I called my poor-man's surface grinder. The finish is actually quite nice, and very long grinds are possible.

Buy a sherline head and put it on?

I did think of making a head which must be just about the easiest part to make for a lathe.

I hadn't thought of that, thanks.

Maybe a universal cutter/grinder to sharpen drills/endmills?

That's intriguing, I wonder what else is required?

Apart from the grinder, which you could mount behind the bed on some kind of elevating/swiveling column, you'd need fixtures to angle the tools, maybe an air bearing spindle for sharpening reamers and endmill flutes... Cut could be put on with the cross-feed, traverse with carriage-feed, could work really well! I can't see why it wouldn't work as a surface grinder too, although small and rather less accurate than a commercial one... Traverse speed might be a problem for surface grinding, but the carriage feed could be motorised/automated....

With a double-ended grinder you could have alumina and diamond wheels mounted for HSS and carbide but might need to be able to flip the grinder around - easy if it's made to swivel on the column.

Take a look at Quorn, Stent and Bonelle TCGs on the fora, lots of ideas there, and a few commercial TC and surface grinders for inspiration!

Remember though, it'd throw a lot of very abrasive dust around, not good for other machines, so you might want it outside your main work area....

You could make a nice milling attachment for a bigger lathe out of it.

Further to the T&C grinder theme, there was an article in MEW (July 2006) that was titled "Sharpening with diamond discs". The author used the bed and carriage of a Unimat 3. I tried out the concept and, surprisingly, it worked quite well. Ended up making a T&C grinder from a Goniometer and a Foredom grinder.

Let me know if you are unable to access it.

YOU SUCK!

To be honest, as much as I want it to, I don't think it suits for a tool and cutter grinder - grinding dust and swarf will tear (lap?) that brass bed to oblivion in short order.

Do you have a need for a gear hobbing machine? Or a pinion mill? This guy used a Taig bed and headstock, and some CNC wizardry to make a wheel cutting machine (http://www.jeffree.co.uk/pages/cnc-wheel-cutting-engine.htm).

Sometimes I wonder where you guys seem to find all this useable 'junk'!
