One of my favourite tools for smaller work on the Myford is one of these
Comes with a sharpening jig. Super simples.
Link doesn't work for me?

It's really nicely made and makes HSS tool grinding idiot proof. Running costs are pretty low compared to inserts too ..I have seen that before. Seems pretty expensive.
That's why I ended up not buying it. Seemed expensive for a lump of steel with a hole in it.I have seen that before. Seems pretty expensive.
I thought that until I saw them in person it's all cast tool steel so top quality.That's why I ended up not buying it. Seemed expensive for a lump of steel with a hole in it.
Fine for home/occasional use when you have time on your side but if needing to remove a good amount of material and quickly then HSS is not the way especially if it is material other than mild steel.I thought that until I saw them in person it's all cast tool steel so top quality.
Easily on par with the Iscar parting tools I also use.
Running costs are pretty much zero as you can easily regrind the HSS with the supplied jig and a offhand grinder. How much do decent inserts cost?
I agree but we were talking about getting a decent finish on old slow / knackered home gear not a production environment....Fine for home/occasional use when you have time on your side but if needing to remove a good amount of material and quickly then HSS is not the way especially if it is material other than mild steel.
I started out with HSS and when doing, for example, 316 I would be grinding the tool every few passes.

Lol no!Ha ha, better not tell @fizzy his Roundhead is a pos
If it's a felt seal I might be able to make one on the CO2 laser cutter....Lol no!
Very miffed yesterday - a part I was turning - 7/16 diameter - was out by 4 tenths over 8" - just not good enough
The old girl has developed an oil leak though - looks like it's from the rear bearing seal possibly.
Not losing much - probably can go 3 months before it needs topping up but rather messy.
Thanks for that.If it's a felt seal I might be able to make one on the CO2 laser cutter....
Similar style tip to the one I posted pictures of.I've posted to my thread but thought I'd mention here too...
I got a new toy tonight... SVHCR and some VCMT16 inserts from ebay

So, bear in mind this is gummy black bar, maybe EN1, maybe ungraded. This was a 0.5mm DOC, 25mm dia, 1000rpm, 5 TPR feed.
It's almost flawless! Again, pictures pick up more than the naked eye does, it's almost mirror finish. If it was a better steel, I think it would be flawless.. but then again, better steels give better finishes anyway.

I like this tool and these inserts very, very much. I only wish I'd got it with a 25mm or 30mm shank.
Added bonus: if you're lazy you can get a badly angled chamfer on one side shoulder by using the far edge, and run the lathe in reverse to chamfer the other side shoulder... ask me if I tried well it takes the sharp edge off anyway!
Downsides: It doesn't like deep cuts. I pushed it with a 3mm DOC and was rewarded with a hot stringy mess. It also doesn't like higher than 5 TPR feed. So no good for roughing. It literally likes 3-5 TPR and 0.5-1.5mm DOC. This is more or less exactly within the parameters written on the insert box. It doesn't mind going slower, too.
This is the tool:

The VCMT inserts I linked to aren't designed for aluminium, they're designed for steels. So you can work them a lot harder and the chipbreaker works really easily.Similar style tip to the one I posted pictures of.
Very nice but a bit more expensive.
Yes the ones I have are very fragile!The VCMT inserts I linked to aren't designed for aluminium, they're designed for steels. So you can work them a lot harder and the chipbreaker works really easily.
I wonder if it was your original post that got me thinking I wanted an angled VCMT tool? The angle on this is great for turning and facing up to shoulders, loads of clearance for fiddly stuff too.
