A project I’m working on requires cutting a design out of a hollow cylinder and replacing it with a clear resin so there’s effectively a “window” in the cylinder. Any suggestions on how to achieve this? The problem of course is that the resin runs. It’s essential that the outer surface of the resin be flush with the cylinder, and whilst the inner surface is less critical, the cylinder does need to remain hollow.
I was thinking of applying thickened silicone to the cylinder’s outside before cutting the design and then creating some sort of former for the inside such that I effectively cast a clear cylinder for the full height of the original cylinder, but I’d only have a millimetre or so clearance. I don’t know if the resin would fill such a narrow gap reliably, and there’s also the issue of removing the former afterwards.
The cylinder I’m working with is 25mm diameter. If anyone has any clever solutions I’d like to hear them!
