Chipping Moulding

[EHT1]

Chipping on the side of the frames

My Frames sometimes Chip on the back / Side edge why is this? The moulding is a Square foil moulding 30mm x 30mm

I am using a Moros to cut my frames. I have tried the following putting new blades on the Morso putting tape on the fence of the Morso.
Could the grain of the would make a differences ?

Can you give more details of the moulding, supplier, catalogue number then we are better able to share experiences.

This subject came up a while ago on a particular range of mouldings.

There are a lot of mouldings that use a very hard and brittle coating. Not to mention thick. They chip even with sharp blades, but the hard coating dulls the edge very quickly and the chipping will then get progressively worse. This type of moulding is aimed more at the mass-production market where you can bang the stuff though an automated saw setup.

If it's not that, it could be the wood. If you pick up a length you can usually gauge the weight. If it feels light then the wood will be very soft and liable to tear, compoed or not.

Heavy compo mouldings are the bain of any morso user. As prospero says they blunt your blades and usually chip on the back no matter what you do.

If you post up the moulding someone may have experience of it.

I have a very simple approach to this type of moulding which seem to be becoming more prevalent. Some have compo that is so brittle that they are even problematic when cut with a double mitre saw.

Step 1. Complain
Step 2. Send it back.
Step 3. Demand a refund
Step 4. Remove the sample from your display.
Step 5. Never buy it again.
Step 6. Inform the supplier that it's crap and that you will not buy it again.

If more framers did this, the manufacturer might get the message. The more of this stuff that sells, the more they will produce it!

I get this problem with Arqadia confetti range, amongst others. I do like the moulding and one solution that works quite well is to heat up the area i am about to slice with a hairdryer, it definitely feels softer and less brittle to cut and the finish is much improved. If its not a moulding i particularly like then i would dump it

[Roboframer]

I dropped that confetti range in favour of Simons Festival range, the smalller profile is slightly narrower and the larger slightly wider and not as deep, but much thinner coatings over better quality wood, slightly cheaper too, similar colour range.

Finger jointed pine + thick brittle gesso = No Thanks!

I used to have a problem with a particular arqadia moulding which I used by the case. It was finger jointed balsa wood covered with about 2mm of gesso. It always chipped, so I asked the rep (not the current rep god love him|) who said I should use a saw to cut it. Fine but how do you join it?? the wood was so flakey it made certain plastics look like solid oak

Anyway I moved over to a plastic half the price . However that was discontinued and I am back to the old moulding but now improved 1000% no problems.

You get what you pay for unfortunately and I would suggest for bespoke work try using a better quality moulding or substitute with a plastic. Saves you money and grief in the long run.
