A diamond toolholder toolholder

Thanx for the review, Don. I have been considering one of the "diamond" tool holders for my Sherline.

I think you'd like it. It cuts with very little force, which is good on a small lathe. The included jig makes it very easy to grind the tool properly on a bench grinder. You can knock a small radius (.032 or so) on the front corner of the toolbit with a hone to achieve a very acceptable finish on aluminum, brass, mild steel, SS and delrin (plastic). If you do that for about 1/4" of the length, then you get many regrinds without having to re-radius.

And what do you use the diamond-tool for? I only use that shape for free-hand turning (holding the tool by hand, with a long lever).

I use it for turning and facing aluminum, brass, delryn, mild steel, drillrod and 303 stainless.

I do use carbide on cast iron, abrasive stuff like glass-filled Noryl, and on hard stuff like truck axles and nastier SS alloys.

Ah! Thanks. Grinding position is almost working position.

The shape for freehand turning I meant looks the same, but the long axis is horizontal. :-)

Me too. Using carbide less than once.

On your page: "Only problem with it is that it wants to be positioned at a 12 degree angle WRT the Y axis of the lathe. That's inconvenient because then I must rotate the toolpost every time I change from turning/facing to parting, grooving or threading -- and again to change back"

Is there a reason that the basic toolholder couldn't have the additional

Nicely done, Don!

I made my own tangential tool holder a few years back on my Myford. It's not pretty but it works very well.

I got the hots to make a copy of the Tripan toolpost for my lathe. Other than setting up to cut a couple dovetails at angles to each other, it looks good to me. Lord knows I'll never buy one new. $$$

I built one to see how it worked last summer for the experience. See my pages on Earthlink home.earthlink.net/~lhartswick/ Just a bunch of pix, on fancy stuff. :-) ...lew...
