Thank you all for your interest.
@ Lee : I have designed the frames with a tolerance for a tight fit, but I'd rather avoid sanding flat sheets. I keep lokking through my stock to find the best piece of card.
In the meantime, I want to stick to my plan of cutting frames on masking tape, but for the time being it is rather my plan that is sticking on the Silhouette. All my attempts to cut new frames have failed: the paper is sticking to the blade, the blade tears it off, then the paper lifts and clogs the Silhouette
. Changing the blades does not yield any better result.
I think the issue comes from the machine's cutting mat that is too worn out. I need to order one new cutting mat ... and new Tamiya masking sheets
So the project is on hold for the time being whilst resupply comes in. I'll focus on my Jurassic Gee Bees in the Jurassic GB
in the meantime.
