Thread: M2 HSS Turning Chisel Batch Order

Just for comparison sizes

Scraper sizes:
My Sorby scrapers are 5.95 mm and 6.29 mm thick
My P&N is 8mm
Northwood cheapies approx 6.5mm

For skews:
Thompson 1 1/4" is 8mm thick
P&N 24mm is 8mm thick
P&N 12mm is 6mm thick

Regarding Scrapers - We could make chisel blanks with square ends, then people can grind what ever shape and purpsose they like. What do people think? Say 12, 20, and 30 mm wide out of the 6.5 mm sheet.

Regarding the scraper tips, it would not be a problem. If you could get me clear photo (top down plan view) of the exact shape / radius of the tear drop and any angles on them, and all dimensions of any other types of scrapers, they could be made from the 4.5 mm sheet.

The RUFF cost would about $10 +/- ($3 steel, $5 waterjet, $1.5 heat treat), NO grinding. Grinding would add another $25 to the cost.

I can give you a pic against graph paper of the Sorby tear-drop and the Munro version.

IIRC they both come with a square edge.

Grinding that leaves distinct scratches that need polishing out would not be an advantage in my view. But if the cut steel is not flat the scrapers are best lapped and polished anyway.

Here ya go; on 5mm grid.

Left one is the Sorby, 3mm thick. The right is the Munro, 2.7mm thick.

Haven't bothered to pic a Woodcut; not a fan.

This Sorby has a bevelled edge but I can't recall whether that was from the factory or I did it.

These are finishing tools in my book and benefit from a refined edge. Lapping the Munro took forever and as you can see I ran out of puff.

Sorby recommends sharpening by running a diamond lap over the top face. So you are not cutting with a burr.

I have a slight pref for the Sorby shape; a bit more versatile than the Munro.

HTH.

Here is the draft drawings of the scrapers.

Ern can you confirm the dimensions.

Nice CAD work Helmut.

Corrections added.

If you go down this route put me down for 2 of each, unground.

I have updated the CAD

Further to my previous post regarding the scraper tips, I'm very interested ...
but ...

... ... ...

And is there a final price (per 'tip') yet?

Thanks in advance

thumb trimmer - The RUFF cost would about $10 +/- ($3.5 steel, $3.5 waterjet, $2 heat treat), NO grinding.

Grinding would add another $25 to the cost.

Once we have filled both sheets, a PM will be sent regarding payment option.

thumbsucker,

Please put me down for two of each (of the scraper 'tips'), unground.

Thanks
