I've been asked by our Pastor to cast a 3" x 22" "Christ Candle". I haven't
been able to find a candle mold this big. I have a few feet of new 3" PVC
pipe that I can make into a mold, but the inside is rippled from the
extrusion process. Any suggestions as to the best way to make the inside of
this true and smooth so that the candle can be extracted after molding?
I''ve thought of running a cylinder hone down it, but this will probably not
do exactly what I want, and will leave a grooved surface.

I've thought of buying a piece of 3" copper drain pipe, but this will be
expensive and may be unobtainable in a two-foot lenght. I don't have slip
rollers, so I can't see how I could roll a mold. Any other suggestions?

Thanks for any help or advice you can offer.

I don't think you are going to have to worry about release. The
coefficient of thermal expansion for wax is probably higher than PVC
which will leave clearance when it cools and it should fall right out. I
would not worry about the ripple. I think you will be able to smooth it
by playing a flame or hot air gun over the outside of the candle after
it is cast. These are just hunches, I'd try a small one first, may be
3/4" PVC pipe.
