I have just fired up my Cougar Black Cat cutter again, after a couple of years lapse due to illness and house moving.
This forum no longer recognized me. I had to register again.
My current problem is finding some stiff relatively rigid waterproof material that I can use to make forms for light weight concrete pouring. The normal 3/8 inch foam core board will not fit under the knife holder or the rollers. I cannot see a way to raise these things. I have a small piece of 1/8 inch styrene sheet that will fit, but the material is fairly hard and I am not sure that the blades will cope with it without breaking.
I could cover medium weight chipboard with stick on Mylar, I suppose. However, the chipboard stock that I have just bought will not stick properly to the newly sprayed cutting mat. Besides, I will have to cut several pieces and glue them together to get the material to be sufficiently stiff.
One set of pieces will be glued together to form a "plug" inside a square plastic bucket mold. The concrete will be poured or tamped in between the bucket walls and the plug in order to make the hole for the earth and plants. I have considered trying to make this plug from the chipboard, covered with stick on mylar, with the inside given rigidity by spraying it with Great Stuff foam. This might work - - or not. The main problem is that it will probably only last for one pouring. I would have to make a new one each time I wanted to use the mold.
Another project is to make inserts for a seed grower that will hold 19
plastic cups upright. It is round, with cup-shaped holes in it and
eight "feet" around the edges that I will have to bend to a sturdy right
angle. The feet sit in water in the base of what is actually a round
cake container. It will be constantly damp. I have no clue what to
make these pieces from.
