I was jonesing to try a Neg Rake scraper

[Raul McCai]

There are some expensive ones out there

Got some steel bar stock
Found a half inch hunk of HSS tool bit
Welded 'em together

It works

Looks like it works fine.

Yah now I gotta handle it and call it a tool

Good idea and great looking tool. Where did you find the HSS? My son has contacts in their machine shop so it would be no problem to get one made.

I've got some smaller pieces of HSS planer blades. They aren't very thick but if I mill a slot and put them in there like Stewart Batty did it would probably work.

Where did you find the HSS?

In another life long ago and far away I was a machinist toolmaker. I worked so many shops. So I still have stuff. It's also how I put myself through college. Odds are you son can get a piece of HSS that'll do the job nicely and even find a guy with a TIG to put 'em together.

I believe Stewart's is held in place with set screws. I haven't seen it in years so my memory may be foggy.

 

[John Torchick]

My son has friends in the machine shop at work. I don't think he welds but could find a guy who would do it for him.

I like this tool so well that I'm making another only this time the tip will be a disc of HSS sort of like the a french pattern box Scraper with a round off to one side

Here's the finished handled tool

Wow, that's the longest scraper I've ever seen.

Wouldn't it be long enough if you just attached the handle to the flat bar? It looks like the coupling is bound to allow flexing.

It looks like the coupling is bound to allow flexing.

Hasn't flexed yet.

The coupling is inch and a quarter diameter. The flat bar is 3/8"x1". Plus the scraper is not a hogging tool. The way I use it I get a small edge and take light passes.

The handle part is from my hollowing rig. It's just doing double duty.

For fine shavings it ought to be alright. Make sure it is above center when doing the interior and slow usually, but not always gives a cleaner result.

 

[Raul McCai]

above center

thanks for that. It's an easy thing to forget.
I have this rest I made that is a flat bar 2" wide that I can shove inside the bowl right up close to the work. With the Neg Rake tool it's really sweet because there's no need to up angle the handle. I just leave it flat on the rest.

 

[Bill Boehme]

And the back of the handle should be raised a bit so that the tool is trailing down slightly. The reason is that the wood should be moving away from the scraper rather than pushing into it. If it is a negative rake scraper, you can have the tool level and slightly above center.
