Morso Cut Problems

[DrumpellierFramers]

Hi everyone,

Hoping for some advice. I'm new to framing and still very much learning... I've bought a used Morso F but struggling to get some of the cuts right, especially deeper rebate mouldings.

I've included an image to explain what I mean but the cuts, although dead on 90 degree are not meeting at the top of the moulding but are at the bottom. It's as thought the machine table is not at 90 degree to the blades.

I've got a digital angle measuring device and the blades seem to be at 90 degree.

Does anyone have any suggestions?

If it's relevant, the moulding is a 32mm deep Polcore moulding.

Thanks very much, David.

I can't speak for Polcore, but the first thing to look at is your blades. Buying a new set of blades usually sorts everything out. Morsos are often sold with a pair of blades which even if freshly sharpened can be passed their best in a number of ways. If you can afford to stump up for a shiny new pair, you won't regret it. As a non-polcore framer, I'd also suggest getting your hands on some plain barewood moulding, preferably a flat profile, to do some further tests with, the wider the better. For an instant test to see how sharp your blades are, put a strip of paper in place of the moulding and cut that. It's only a simple test but it should cut effortlessly.

Sharp blades - essential.
Cut in the mitres step by step - not in one clump.
Hold the moulding firmly down on the Morso bed when cutting - most likely fault
Polycore instead of natural wood - always an ill advised choice.

And that's from someone who doesn't even own a Morso

Thanks for the advice folks. Yeah, with this being my first Morso I’m not 100% on what actually are sharp blades. The ones I have seem really sharp but not able to actually compare them to a newly sharpened pair.

The moulding is firmly and fully flat on the table and up against the fence so no issues there. First thing I’ll try is the blades but still not sure as the right side of the length is trapped in mitres stop beam so struggling to think why it would be thrown off.
