1 3/4 inch casting tubes

[montmill]

I'm casting some handles for scoops, pizza cutters etc. and have schedule 40 tubes 1 inch and 1 1/2 inch. The next size is 2 inch and if I used that I'd have a lot of wasted material. 1 3/4 id would be perfect. Does anyone know of a material that would be 1 3/4 id and hold up to Alumilite Clear Slow? I should add I'm casting stabilized wood. Thanks for your help.

I use empty caulking tubes , such as Dow 732 RTV sealant . They are about 1 13/16 . I use 1/8 hardboard as a base , 732`d to a short length of tube when needed . All of my casting is Alumilite Clear Slow , or its predecessor which isn`t quite so slow .

I treat them as disposables , and cut or turn them off . Never tried mold release .

Schedule 80 PVC has a thicker wall so the ID is slightly smaller - 2-inch has an ID of 1.9 inches vs the 2.047 of Schedule 40.

Optionally, you could turn a dowel (or dowels) to the dimension you want and then use some Alumilite Red Amazing Mold Maker to make your own Silicone Mold to be the exact dimensions you want.

Go to Amazon. Look up polycarbonate tubes of any size.
