I need to make a hole that will allow 7mm diameter elastic to be fed through. Almost the entire length of elastic is 5mm diam, but there's a "bulge" at one end which will eventually be at the catapult end.
There will only be one piece of elastic at each side of the pouch, because there will be very little strength used. It's only to scare the to feed the crows at the end of my 60 ft garden.
BTW: I don't see any need to fit grommets for safety. I was planning to double over the leather at each end of the pouch, so the elastic is actually piercing two concentric holes. Does that sound OK?
BTW: Just to prove that I tried, I tested a piece of the candidate leather. I used a sharp awl which widened out to 2mm. Then I widened that hole with a 3mm Phillips-head screwdriver. Then with a 5mm screwdriver.
After that, the hole is still not big enough. The elastic is not stiff enough to force its way through all the rough edges round the circumference of the hole. Also, any larger screwdriver would begin to rip the (very soft) leather, and might be a safety risk.
Thanks.
