Chopping moulding with a curve in the back

[Sandi]

I have a Morso Chopper and when ever I chop moulding with a concave back the chopper blades tear out the moulding. Has anyone come up with a way to chop this kind of moulding successfully.
Thanks

I've tried filling the curve with putty and also putting a piece of half dowelling in, varying degrees of success.

These days I just avoid those profiles unless unfinished.

There are some mouldings that you just can't chop.

Concave back would be one of them. You really need to buy a saw or order the difficult profiles chopped.

I always had trouble with really thick compo mouldings.

I ended up buying a saw just for these (and it comes in handy for a bunch of other projects)

The only other option for me is to order them chop.

A support made of wood or mat board, which fits the back of the frame, can help, here.

You can use matboard or foam core like Hugh said, but that is time-it might be cheaper in the end to have them chopped until you get a saw.

This has been discussed previously ( do a search) there aresome Wing back profiles that lack support ,no matter how well you back them ,and how sharp your knife blades are .This will cause the pressure of the blades to crush the unsupported segment of the profile . the methods suggested will help but not always .
