For those interested in a less daunting, and less adjustable option, here are a few photos of an Armstrong original.
It is up for auction on US Ebay - Item number 230726750926
I must say Ray, your prolific output of work is more than impressive. I'm struggling with drilling one hole.
Dragging my feet,
BT

Ray, I got a bit lost with that video as well to be honest. Don't worry, Stuart will explain it for us.
In practice, I'm sure the Armstrong type that Bob posted would be plenty adjustable enough. Remember the toolpost swivels. So far I haven't needed anything more sophisticated than a bar with a hole.
Edit: That holder on ebay only takes a 1/4" bit, so it's Douglas-sized.

Hi BT,
One thing I notice about that tool holder that Ray may wish to add to his is that each face the tool can sit against has a groove cut though the middle of it. I guess this is to ensure that the tool must sit on the corners so it cant rock?
As for the video, The first op he is cutting away the tops of the teeth(before the teeth are there. He is machining the concave with X axis feed we poor people would have to set the dividing head on an angle). Its ensure(like the last paragraph) that the two parts must clamp on their faces and not the tip of each tooth(something else Ray may like to do). So both parts end up the same with the flat faces on the peak of the teeth being a concave and the valley of the teeth being convex.....
(If he had turned the crank pin in the lathe rather than milling it he could have turned a concave face first rather than milling all the slots, I think)

Hi Bryan,
I could drill that hole for BT, but it would be either a) wrong size b) wrong position c) not straight d) drilled in the wrong part ... or more likely all of the above..
Next dumb shaper question.
What makes a shaper vise? How is it different from a milling vise?
Is it just size?
Regards
Ray

Shaper vises are not just heavier, they also have four mount holes (which makes T-slot spacing an issue). Mine (an Elliot) also has four swivel bolts; I don't know if that's normal. There is something about the screw as well. It goes through the fixed jaw and the thrust face is on the outside, so it pulls rather than pushes. Does that make sense?

Hi Ray,
Price?
The shaper vices I have seen are held down by four Tee bolts onto a square swivel base and the square base is held down by four Tee bolts(unlike milling vices held down by two and two). The screw closing the jaw is in tension not compression(maybe due to the load being towards the moving jaw?).

I think I need to join Phil's support group... the first little taste of running a shaper, is very addictive..
I haven't got around to sharpening any bits yet, I just grabbed a lathe tool (too impatient)
I think I screwed up the cutter position, it was supposed to be in line with the front of the tool mounting, but somehow ended up in line with the front of the clapper.
Anyone got the number for that support group?
Regards
Ray

Hi Ray
Congrads.
Starting to wonder how you ever got by without one yet?

Ray, just set it to the finest feed on a large piece and see how long it takes to get bored.
And to answer your earlier question: Sure you can use a mill vise, just keep the cuts light. Under 2mm say. In fact I would work up gradually from 1mm and keep a hand on the clutch. Oh wait, you don't have a clutch, right? Edit: I just checked your other thread and I can see the clutch lever. Don't know why I thought that.
PS: The holder looks slick.

Ray a top thread which has shone a light for me to a situ I am trying to get around in OT.

Hi Stuart, I never knew I needed one so much... Much more fun than milling, quieter too...
Hi Bryan, I read your post too late, I already did a 2mm cut, (took a video which I'll attach to this post when it uploads.)
The milling vise will have to do until I can either find the original vise, it must be in Wangaratta somewhere, probably being used as a door stop.. or a boat anchor.
Thanks Ray, based on zero experience, but a bit of imagination, I can see a lot of applications where a shaper will become the best tool for the job..

PS I'm getting a bit of occasional tool bounce in the middle of the return stroke, which you can see in the video, any ideas?
