Tool and Cutter Grinder

Hi,

Unfortunately the Axminster grinding rests only articulates in one axis plus vertical movement while Mr Halls articulates in two axes plus vertical making it far more versatile than the commercial one.

I use the original bolt down method, but with two angle irons at right angles to each other on my grinding table, which is a piece of 12mm plywood which I clamp to any suitable surface when I need to grind a tool.  I don't find this at all inconvenient and much lesss expensive than the magnetic bases.

Best regards for the new year,

Terry

I have one of these. You are quite correct - it does need another axis and it would be possible to make one however the whole thing lacks rigidity as it is and that add on would only make it worse. It is OK for woodworking tools and perhaps lathe tools but I wouldn't recommend it for cutters.

I have a 70% complete Stent that may get finished one day and that has been an interesting journey - I could have bought a lot of cutters for the price I paid for the bits though.

Hello Norman.

I also have one of these.
I mounted it on a two crossed axis as you can see here ***LINK***

Nice crisp knurling there Dias.

Doesn't have to be so complicated though. Found this the other day (skip the first 30 seconds - why do people have to talk to camera unless they are nubile females of course)

Not necessary for lathe tools really but the adaptation for slot drills would be even simpler to make.

Hi Dias

Here is a picture of the rest Terry and I were referring to. Not in the same league as your sturdy effort as you can see!

Hello Norman.

Thank you for calling my attention to my gross mistake.
Now I can see you were referring to a something completely different.

I wish you a happy new year

Hi Norman,

These rests are really intended for grinding woodworking chisels and plane blades before final honing, not really for machine tool bits. For the cost of these it is really quite economical and more useful to make the one by Mr Hall in his book. it didn't take me long to make mine and it was an interesting exercise refreshing many of my rusty skills.

Best regards and seasons greetings,

Terry

What is the recommended board size to mount the grinding rest and grinder on.

I am thinking in the direction of a thick wooden board, covered with a 3mm (1/8" sheet of plate. I want to mount the grinder on a raiser block(S) so that I can expand in the future to the adco tool grind setup as well. The "Hall Toolrest" with the magnetic configuration can be moved to where you want it.

1)Board size

2) where must the grinderbe mounted?

ADCO???? google just brings up this thread!

Hi Johan

I would suggest you fix your steel plate to a piece of thick laminated kitchen worktop. With the cut edges of the worktop sealed this should form a stable base for your grinding set up. You should, with luck, be able to source a suitable off- cut cheaply.

If you place your grinder and base-board in a baking sheet (kitchen ones, for making cookies and pizzas etc) it will catch a lot of grinding dust that otherwise migrates all over the bench.

Sorry It is the Acto. Bad spelling.

I want to make the Harold Hall set-up and then later as a model project make this one as well. Both can sit on the same mounting board. And both can benefit from the magnetic base set-up. Then I don't have to make rails for the acto.

Here is the link:

I have seen no reviews yet, but I have seen several good ones of Hall's design. Several of the other designs (Quorn, Bonelle, Stent excluded) are basically similar. Where the Quorn and Bonelle have double rods for a base to move the platform, this Acto has rails as well as an X,Y slide. However for me the Hall design has the reputation backup of Workshop series books and the successes of his models made so far.

Hi Johan

Have you seen the article in MEW 134 Jan 2008 pg42 Tool and Cutter grinder from a junk box?

It may be possible to use a cross vice for x y travel, somebody on this forum has done this already.

You will need some kind of swivel to get the rotational angles.

I like the idea of bolting things together to get an end product I don't have the patience or probably the skill to do it from scratch. Just make up the little bits to make it work!

Cheers Michael.

Perhaps they will all be obsolete soon. At Sandown someone on a SMEE stand was showing a CNC style system rotating an endmill in step with moving it along the grinding wheel.

Hi Bazyle

That was John Pace.

His CNC cutter grinder has already been described in MEW.

Hi DC,

You sure Bazyle was not referring to Prof. Hugel's excellent example?

Hi ChrisN

No idea.

Perhaps you can ask him.
