Making tools for shaper

[Paul MajorParticipant @paulmajor25237]

Hiya, whilst refurbishing the mill I am keeping myself amused playing with the Elliott 10M Shaper I picked up the other week.

It came with a variety of tooling, most of which seems to be to large to fit in the tool post or too small.

I have read all the stuff I can find about grinding tools for the shaper including the articles on NEMES and I am struggling to get my head around the shape of the tool in 3 dimensions. I know I am probably just being dense but its kinda one of those things I need to see to understand.

Does anyone have any pictures of shaper tools that show the shapes from various angles?

Also, if the tool is too narrow for the slot in the toolpost is it acceptable to just shim out the gap?

Cheers,

Paul.

Hi Paul,

This may help you with visualising shaper tool profiles.

There's a bunch of useful stuff here

Shaper tooling can be a lot like lathe tooling in shape much depending on material and the job in hand IMHO it needs to have less “front” clearance typically only around 3* to 5* to cope with the high intermittent cutting forces of the Shaper and to maintain a robust cutting edge for as long as possible.

If the tooling is too small shimming/packing is quite acceptable, I would avoid having the tool too far away from the face of the clapper as this can cause chatter and poor finish. Irrespective of machine type I find better finishes are obtained when the tool is slightly rearward of the face of the clapper say when mounted in a rear facing “Armstrong” type of toolholder.

I can recommend some reading for you: Ian Bradleys book on the Shaper and “Lathe & Shaping Machine Tools” by “Duplex” in the “Duplex” book he goes on to describe the construction of an Armstrong type of toolholder manufactured from a Bicycle Crank I can say that they work quite well.

Hi Paul,

I don't know if you have found this tutorial? It has drawings (p. 6) of several types of cutting tools for a metal shaper.

I don't have a shaper, but I have the Duplex booklet and it gets my vote.

Shaper's are like lathes, anything with an edge that you can clamp securely in the right place should work to some extent.
