I imagine you had a great heap of chips after that. Great idea using the parting tool. Will give that a try.

Thanks Greg, I'm just making it up as I go along- I couldn't find any information about making a cut like this with the shaper and it seemed to make sense to have a cut to work to, much like threading to an undercut on the lathe. Would have worked better if the side cuts were wider than the tool used to take the guts out, this would have taken away the need to plunge the round nose tool at the start of each pass.

Somewhere on here is a link to some shaper literature, that I'm pretty sure had info on cutting tool grinds and applications. Hopefully this will prompt the person who originally posted it to chime in, as the search engine here couldn't find a Frenchman in a brothel.

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.

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.

Did the dovetail cuts.
Tool cutting the first side:
   
I had a few trips to the grinder to get the tool geometry cutting well. I was happy with the finished cut on the first side so I replicated the grind in reverse on the other end of the tool to do the other side.
   
Test fit.

But you don't know if that was on the first try...

Got some actual machining time today. Rebuilding the quick attach for the bucket on an excavator. These arms don't have bushings some bored them out to go to an oversized pin. Already made bushings for the end of the boom.
