The Harold Hall one must be a serious contender

Look in either MEW 89 or his book "Milling – A Complete Course"

Hi Adam,

I've never come across a commercial lathe tool sharpening equivalent of a twist drill sharpening jig.

If you want to buy a grinding table, have a look at this one on ebay **LINK**

Adjustable table angle plus a protractor should give you what you need. All you have to do is get the tool the right way round.   It's up to you to mount it in the place you want in relation to the grinding wheel.

I used to have one of these until I made something more hi-tech. It's probably still around somewhere, too good to throw away!

As Andrew says, you can manage with a standard grinder, but I found I was grinding/burning my fingertips!

Instead of a wobbly adjustable jig you can get an angle on the ground edge by rising above the centre line of the wheel when grinding on the edge not side. The amount of rise can be calculated, estimated by eye, or by making a drawing. You only ever really need 5 and ten degree settings anyway.
You can get up to height with solid squared up blocks of 4×2 wood perhaps notched to fit a little each side of the wheel. Pieces of thinner ply can then be added to increase the grind angle. Then top off with a steel plate say 1/8 thick to give a smooth slidey surface.

If you do not want to make your own tangential tool holder, get one from Eccentric Engineering. Comes with a simple sharpening jig which is easy to use on most grinders.

Ouballie The alternative is worse

Not really your weekend is it Neil ?

Search for "Universal Sharpener "

Hi John how would you actually use this tool holder – have it moveable or have the grinder moveable?

Looks like Trevor was first off the mark on the Shars unit while I was still writing. Importing one would be way more than £85 as they would ship by 'extorsionmail' though I have seen reference to a new system of using a 3rd party consolidation shipper.

Bog's unit is a (home made?) 'universal head' common for most tool and cutter grinders eg Clarkson (this is a great site by the way if you have a clarkson fetish). These are horribly expensive when they come up alone hence need for nice casting to be produced. Ok you can make something out of a bit of big angle iron section or cast angle plate but it's not the same and nobody seems ot make a cheap unslotted 3in angle plate casting.

The AMA is pretty cheap for a universal vice but Harry on ebay is actually our friendly 'shopping partner' on this site Amadeal who also support the Briston show and are very good value.
