Thread: Shaper Tools
11/06/2010 14:38:29
Thanks to all who have replied.
 
Many of the links have provided usefull information.
 
It appears the use of Jogged or Swan Necked tool was for Earlier machines or much heavier work.
 
Just need to get some time to solve the rigidity issues on the mahine and I think I should be sorted.
 
At some time soon I will put up some pictures as I have been unable to identiffy the manufacturer and would like to replace the missing parts for the automatic table feed.
 
Thanks to all

I have recently purchased a small secondhand hand shaper and have been trying to get to grips with it's use. I have no experience with such a machine, and I quess that those that do are few on the ground; the milling machine long having taken it's place in the workshop.

I am having issues with the tool digging in and ripping rather than cutting on all but the shallowest cuts.

The machine has some rigidity issues which I am in the process of rectifying, 5 thou measurable deflection between the bed and clapper. under load. However it may also be a question of tooling. currently the tool is being drawn into the work (similar issue to that on a lathe when parting).

As supplied it came with a slightly joggled tool placing the cutting edge about 20mm in-front of the clapper box pivot. My older texts suggest that the cutting edge should only just lead the pivot, however all photos I have seen show straight tools.

To my questions:

Was there a change in normal practice with regard to the use of tools that put the cutting tools in line with the pivot?

Does anyone know where I can procure joggled tools(1/2")?

Any other advice on how to rectify the problem of digging in most welcome.

Thanks

Martyn
