Hello everyone
I have a couple of questions with regards to filling blanks with resin.
I have just managed to make a mould big enough to hold 2 blanks with some left over. I had 2 blanks that had heaps of holes in them (alot of them going all the way through) I mixed up some coloured resin put both blanks in and filled themould then put it in my pressure pot(yes I finally used it). I kept around 40psi for over an hour then removed them from the pot and all good (i thought).
Everything set well and filled the gaps nicely except when i drilled the blank i noticed that the filling seemed to be moving (Damm) is this right or have I done something wrong OR not done something I should have I would appreciate all the help I can get.

Thanks everyone
Ian

Ian did you let it set and did you remove all the loose wood and remove all the dirt. You may even find that of the wood is to smooth it may not stick.

Two things...
If the wood is an oily wood, it won't stick,
and most people that do WW casts, use Alumilte. They say there is a better success rate since it doesn't shrink.

Gee,
It took me only 4 posts to get a hassle from someone.

This is almost like being a friend of Charlie's, but better.
You don't live close enough to have to physically see.

See you in 2011 when I come down?

Just keep us informed as to when you are going to land. I wouldn't fly too close to the CA if I were you.:)

IanSorry Dorno, I can't help you with your problem, I haven't yet cast anything but I might be giving it a try this year.

Dorno,
You may be able to take the blanks out of the molds in an hour, but typically they are not ready for a day or so. I made the same mistake as well, and got a faceshield covered in red, white, and blue goo

I read somewhere that if you bake them in a small oven that will speed up the process
don't now what temp though and don't let the missus see

Jerry
that wasn't hassle just plain boring everyday sarcasm :D

I tried a blank once where I drilled multiple small holes in a wood blank, then filled with white resin to try and get a spotted effect. A couple of the resin "plugs" did move in the final turning, so I'm wondering if the adhesion of small pieces of resin may not be good, or possibly shrinkage loosens them up or something.

Either way, a few good coats of thin CA and it'll all be tight again :)

Russell,
Most of the acrylics shrink a lot more than we want to think,
However, just pain white alumilite has very little shrinkage, and does a good job of adhering to wood as lomg as it is relatively clean
(and I do not mean West Virginian relative:D)

Unfortunately Alumilite is very scarce and very expensive here in Australia.
