Alumalite is polyurethane ... PU(polyurethane) has a softer feel to it when you turn it (shore hardness) ... PE(polyester) is harder (higher shore hardness) about 85 on the shore scale while PU varies from 45 - 80

Thanks for that David, which is best though in your opinion?

with good sharp tools there isn't much difference between the 2 when you turn them

I prefer Polyurethane but the prices are so high ... I normally just use a water clear polyester unless I'm making a hybrid blank with burr then i use PU

OH, why is that? does it adhere to the wood better?

Aye ... it seems to adhere much better Polycraft FC-6600 Slow-Set Water Clear Polyurethane Liquid Plastic Casting Resin - mbfg.co.uk and this slow setting PU is my resin of choice for doing hybrid blanks

Thanks David

Hi David

I was going to plump for the Alumalite next time for the simple reason of ease, I like the idea of a 1:1 ratio, much easier to measure rather than 1% of the catalyst especially if you just want a small amount for an accent colour

From what I can see on YT, Alumalite would remove that difficulty altogether, Polycraft FC-6600 Slow-Set Water Clear Polyurethane Liquid Plastic Casting Resin has a ration of 1:1.2 which seems a bit easier to work with, might give that a try as it compares favourably with Alumalite as far as cost is concerned.

I spoke to the man at mbfg from the link you gave David and what a helpful person he is... now I'm really confused though but I've put in an order and will see what happens from here. I've got some Alumilite sitting on my desk so as soon as I've got my chamber running and purchased a compressor... well the skys the limit.

 

[Chilprufe]

I've found that mbfg are absolutly fantastic to deal with ... great knowledge and great customer service

And you won't go wrong with that either Vic, he makes some fantastic blanks.

Would love to have a go at making blanks but I am still learning how to turn them. One day perhaps when someone writes a Dummies guide on how to do it !

I could do with that guide right now

I'm diving into a whole new world what with vacuum chambers and pressure chambers, polyurathane, polyester, silicone, releasing agents, colours, pearl ex, moulds, compressors, vacuum pumps.... oh and hoses that don't connect it all together despite buying it all from the same place and talking it through that I wanted it all to work together... ah well....

As I say a whole new world, perhaps I should write it all down as I travel on this journey

Hi PaulM

I hadn't picked up on the vacuum part, all I did was get a sheet of 10mm of Acrylic to use on top of my pressure pot, haven't used it yet but the day is getting closer, I thougt it would be cheaper and save more space than buying a vacuum chamber, I just glues some 50p closed cell mouse pad around the top to make a seal, seems to work Ok, at present the only problem I can forsee is seeing the bubble level, but as my paint pot is about 2 1/2 ft tall I don't think the plasticiser getting into the vacuum pump wil be a big issue, it'll probably take about 8 or 10 gallons to fill it up so thats never going to happen at the price of Cactus juice......!

He is the most knowledgable person on casting and stabilising I have come across. He is the owner supplier of Cactus Juice.
