Thread: Shaper Action AND Power Scraping.

Bob,

Oddly enough I got sick and tired of tripping over the pile of high carbon steel last week and packed it into a wood box. I "think" that there may be some 1/2" stuff among it. I will have to dig deeper. There is probabably 40+kg of it. I know I can't lift the container.

Working it will be a challenge. I would be trying slow cutting speed, carbide and bulk coolant so as not to heat it at all. A sharp carbide drill maybe the go as well.

I haven't tried the stuff yet; but RayG reckons the "D" stands for "dog to work".

If it can be worked; maybe leave it in it's current hardness. It is very dense and 'rings' when 2 pieces are struck together.

If you blokes are trying to make it sound daunting, you've succeeded!

(I knew I should have taken down the dimensions of that jaw while I had the chance)

Bob, if you can send me dimensions of the jaw I'll have a go at making them for you if Ken will kindly stump up some material. I only have MS in that size.
It will at least give me an excuse for fixing up my carbide cutter - although as the relief is only 2mm it may be just as easy to grind it to size.

Stuart,
I have used brazed carbide in the shaper, and to be honest, it really does work beautifully.
I had reservations when I first went to give it a go because I thought it might just smash the carbide.
But I was surprised to see it do no such thing. It leaves a nice finish, not quite as nice as a honed sheer tool, but a very acceptable smooth finish none the less.

Hope this may help some of you decide to give it a go.

Bob,

PM me those dimensions too please.

Michael, please pm me your address, I don't think I kept it. Anyway I owe you a favour.

Ken

This isn't fair on Michael....

How about I have a go first and if I come unstuck I then ask Michael for help. Sounds fairer to me. I will send you a PM Ken.

The inserts I have work well on hard stuff and I'd be interested to see if the carbide works on the little Douglas. And I do have Peter Fou's tool and cutter grinder.

Bob.

for those interested part 2 is up now.

Not too keen on his hand scraping technique... I guess he gets there in the end though...
