Thread: M2 HSS Turning Chisel Batch Order

I'll have 3 of the Sorby style scraper tips - unground- please.


Peter.

Hi TS,

Can I please get 2 x Sorby shape tips and if possible 2 x 30mm skew shaped blanks with no bevels or surface grinding. I'd like to make left and right skewed scrapers.

Thanks

Steve.

I'm thinking of getting some dedicated dovetail scrapers made up for my different sized chuck jaws, for use on both expansion and contraction recesses.

Will probably add a double bevel and use as a negative rake scraper.

I'm currently using small skews for the job, but they are a bit wide for the smaller jaws.

May even add a side bevel to give a cleaner cut on the walls of the dovetail. This might also provide a depth gauge for the recess.

Will do some measuring up.

They wouldn't use up much of the metal sheet, but if enough others wanted something similar it might help a bit.

.

Can I please get one 20 mm skew, one 30 mm skew and one 30 mm parting tool. No surface grinding.
Thanks very much

Sturdee - stuffy - Geoff1153 I have added you to the list.

Give me some drawings and we will go from there.

Thanks Thumbsucker, I would be very happy if you could use the drawings from your Nov 21 post, Turning Chisels v3.pdf. I dont think I could draw better than those, they look ideal to me, but I'm no expert.

Measured up my chick jaws, most have an included angle of 10°

My jaw widths are:

VM 210mm - 10mm
VM 150mm - 10mm
VM 120mm - 12mm
VM 72mm - 9mm
VM 50MM - 7mm
VM 36mm - 6mm

Nova 130mm - 10mm
Nova 100mm - 10mm
Nova 50mm - 6mm

I'm inclined to go with one 6mm and one 10mm skew edge to cover those jaw sizes.

With such a low angle on the jaw (10°) the skew edge lengths are going to be very similar to the width of the bar.

It seems ideal that 10mm and 6mm skews are on the list of options and already drawn up. With just a 10° instead of 30° skew, that would meet my need for some dedicated jaw dovetail scrapers.

So, could I please have:

• 1 x 6 mm wide, 150 mm long overall with a 50 mm tang Skew with a 10° skew made from 4.5 mm M2 HSS, unground.
• 1 x 10 mm wide 150 mm long overall with a 50 mm tang Skew with a 10° skew made from 4.5 mm M2 HSS, unground.

Thanks

Hi Neil

Asking to make one offs is difficult and it complicates matters.

Could you not use the standard 4.5 mm thick skews at 6 and 10 mm wide, and when you grind the bevel adjust the angle to 10º?

I will consider such skews if other express interest in them.

Fair enough, TS.

Grinding a 30º bevel back to 10º would be quick and easy on such small skews.

So make that 1x6mm and 1x10mm standard 30º skew for me, unless there is sufficient other interest in the 10º.

Thanks Helmut

Hi Helmut,

Can I change my order to

1 off Sorby shape
2 off Munro shape

For the benefit of other orderers, a pic is attached of the orig mounts of these teardrop scrapers.

The Sorby is the RS200KT. Also comes with two toothpick scrapers. As a half round rod it's a neat tool allowing shear scraping with the round down and toothpick work with the flat down.

The tear-drop steel in the OEM version is not that brilliant IME.

The Munro fits to an articulated head allowing a wide range of edge presentations. The head is triangular in X section, with the mounting faces at 90* to each other. Carrolls sell this head.

So before folk jump to get the kits alone, be aware that the scraper edges wear rapidly and you will still want several in your kit so you can finish the job without heading repeatedly to the grinder.

Elsewhere I've posted about a simple jig to mount the tips on a platform in front of a dry grinder. Let me know if you want the link.

Hope this helps.

And here is a promo image of it that gives another view with the the tip installed.

NeilS and RSSER I have updated your orders.

First of all, thanks for organising this.

Could you put me down for 1 x 6mm, 1 x 12mm, 1x 20mm, 1x 30mm. All unground thanks.

Cheers
Bevan

Enfield Guy is that skews or parting tools?
