New Tool Holder
« on: September 30, 2012, 12:32:50 PM »
I've made a couple of these now and finally I have one I like!

It was hidden inside this block of steel ...



But a few hours on the Mill coaxed it out  :naughty:







Perhaps a little larger than originally intended and weighing a little over a pound it's quite a lump but fits my 4" BV20 nicely.
Tangential tools can't do everything but are really cheap to run using any small lumps of HSS, round or square that may otherwise lay unused.

Beautifully made Arbalest! Looks factory made. Do you bead blast it to get that finish?

That looks great!  Did you make it up as you went along or did you have a set of drawings to work from?  Either way it is beautiful.

Hi Chris, it's a modified Record BDS 250. The standard belt size is 150mm wide but I've fitted an auxiliary platen to use 50mm wide belts. I also had to fabricate a proper table for the belt, the disc one is good as standard.

I thought it might be a Record due to the colour but the table threw me of the scent.

It's a bit large for me, I just need a small bench top model with a half decent table.

Thanks

This raises a couple of questions for me...

I see that you are using a belt sander to (I take it) sharpen the tool rather than a grinding wheel.
Is a belt sander preferred? Or is it a matter of convenience?
Can a belt sander be used to shape as well? (I suspect that's not advised but I don't know.)
I've done precious little with the grinder I have...I really need to improve my skill in making/sharpening cutting tools.

What kind/grade of grit?

Thanks

I'm with Zeeprogrammer, his post took the words right out of my mouth. I've experimented with some small grinding stones in the drill press and a home made jig to hold high speed steel bits for sharpening and shaping, but I wonder if sanding, with a proper machine, would be better.

Up to this point, I use carbide bits in my little lathe. But, it is clear that there is a lot more that I could accomplish with high speed steel bits. Another aspect of machining that I machining that I have neglected. I have wondered if I should get a good grinder for sharpening high speed steel bits, or would a small belt sander be better?

By the way, that is one beautiful tool bit holder that you made!

There's a couple of good reads on this web site that got me started sharpening stuff with a belt sander,

I am having a small love affair with my diamond tool holder at the moment.

Certainly worth a look fellas.

I got the idea from this Carl:

http://www.robert-sorby.co.uk/proedge.htm

As I already had the Record sander I set about the modifications to use it for both woodworking/turning tools and sharpening HSS bits for the metal lathe and mill. I use grits from 80-200 generally. You can use it for any stock removal but you must clean out any wood dust before going back to grinding metal DAMHIKT. The important part to remove from any belt sander if you want to use it for tool sharpening is the graphite backing fitted to the platen on many units. This material is soft and will deform as tools are pressed against the belt. I simply replaced it with mild steel and it's working fine so far.

Thanks all. This was very useful to me.

One of the links talked about a wax lube. What form does that take? A stick? How is it applied and how much?

Chris,

I had one arrive this week, and I know how you feel. The finish is superb. I think I accidentally sharpened a piece of HSS that gave me this result some years ago, but this is no accident, and I can keep sharpening it.



Hugh.

This is the one I went for;

http://www.toolstop.co.uk/metabo-bs-175-175mm-bench-grinder-240v-p14071?gclid=CLOYmOXehrcCFUzHtAodawIAgA

Only downside so far is the belt size is a bit odd so it's Metabo belts or make your own.

Be careful which belts you buy for it. In the past all belts were "scarfed", meaning they had an overlapping joint which causes a bump every time the joint comes round. You can still get these but avoid them in favour of butt joined belts. These have a taped joint and work much better.

That makes sense ? Any recommended supplier ?

The machine arrived this morning and look like it will do the job very well.
The belts are taped and I really can't feel the join so I'm very pleased.
The belt changeover will be easy too.
Next move is to see what grit grades I can get.
Thanks for the tip.
