That's the link to the US Navy's Machinery Repairman 3 & 2 the training manual for the Navy's machinists.  Chapter 12 is devoted to shapers, planners, and engravers.  It includes the recommended shape of the cutting tools.

BTW, excellent price - free. Thumbsup

I've downloaded the US Navy manual previously on your recommendation Stan. It's an excellent resource and I've learned a lot from it, however I could not find any specific information there on making a channel cut with the shaper. I struggled to find any information on this specific cut anywhere, perhaps because it would be best done on the horizontal mill. Next batch of holders I make, that's what I'll do. I need to get the coolant system operational on the mill before tackling a heavy cut like that though.

Take a look at pgs 6-23, 24 & 25.

Yep the info I needed is right there, I looked through the chapter on shapers and didn't find it as it is in the chapter on grinding of tools. Small diagrams but sufficient to give the idea. I was a bit confused by your page numbers initially as the one I had is a later edition with different numbers to those chapters. Seems to indicate that the 'squaring tool' would be appropriate for the job. All in all I don't think I did too badly with the round-nose tool, somewhere I read that it is a favoured form for cutting both left and right.

Made the hoops for the barrel, used 1/2 inch banding and silver soldered a lap joint.

Free advice is worth exactly what you payed for it.

I've been making a little more progress on my toolholders (don't know how those Chinamen do them for the price...)
Got the long dovetailed piece sawn up into a bunch of blanks. 13 minutes per cut, 5 cuts, that's about 65 minutes of wishing for a coolant system and auto cutout switch on the bandsaw. Another project on the list.
   
I trammed my two mill vices to get these done two by two, ditched that idea in short order. I needed to get the first reference face- either the top of bottom of the holder- square with the dovetail. This was fiddly enough doing one at a time. I ended up taking one vice off out of the way.
   
I don't know what this forklift tyne material actually is, it's tough to machine and I decided that, not just for the squaring process but especially for horizontal milling the channel for the tool, I would need to set up the flood coolant system on the mill, another thing that has been on the to-do list for ages. That became today's spinoff project. I don't want to use the original system on the U2 that has the coolant drain through the machine and into the base- two reasons, I don't ever want to have to clean out the base of the machine again and when I took the swivel table off a while ago the passageways for the coolant to drain through were completely clogged up with a kind of cement made from dried coolant and swarf. The mill is nice and close to the lathe so I have set it up to use the lathe coolant reservoir and pump and to drain back into the lathe. I used some kneading epoxy to modify the drainage outlet in the table to take a hose- only photo I took of the coolant project.
   
Spinoff project complete, I set about squaring up the toolholder blanks. Got three of them done, although I have not done the ends yet as I'm planning on picking up a long 1" endmill for the purpose. The stuff takes a reasonable finish, whatever it is.
   
   
That's about as much as I expect to get done until after Easter.
The coolant system has made another project necessary. Splashguards.

A good way to indicate vices in line with each other is to clamp a piece of 1" or larger TGP in both vises then indicate.

Many times a sq piece of CRS will suffice, just draw file the bumps, etc off the surface against the solid jaws.

BTW, for the operation you're performing the vises do not need to be aligned or even indicated straight with the axis.
