Open for comments good or bad.

Looks good Simomatra sems a lot lighter then when i saw it in the lathe yesterday> To name the colour maybe Pussers Blue. Look foward to seeing more of them I like iit

G'day sam, looks prety good. Nice color of blue.

Sam, is that what everyone calls 'clear casting resin" , if so, how did it turn. Was it brittle and a bit scary to turn or fly off the chisel like a long ribbon.

I must say, a pretty good effort. Well done.

Sam,
Great job on your first foray into blank casting. If you are using the titanium dioxide based pigments, you will find that the colors tend to blend and bleed greatly. With those pigments, it is very difficult to get and maintain color separation. Looking forward to seeing what you come up with next.

As far as I am aware this what they call the clear water white resin others with more experience should be able to assist here. I can't rember where I got the first lot of resin from but it is definitely not water clear as it sets white this ok if you are going to colour the resin. I would like to try the Alumilite resin but there seems to be no agent in Australia NZ is the closest and they will not send resin by air so the quantity ordered would habe to be large to warrant it.

My new order from Barnes was ordered late Sunday and arrived yesterday morning by courier freight was only $10 which was very fair Thank you Barnes for great service.

I am trawling the net at the moment for tutorials.

With sharp too;s the ribbons just fly off the tool. I have found that a Sorenson spindle gouge is an excellent tool.

I have experimented with WOP and CA on the finished blank and both take to the blank quite well.

One of the reasons acrylics get brittle is from too much catalyst. It is more of
a danger in small batches because the ratio is harder to measure in small
quantities. (a few extra drops might change the mix by 10 or 20% !! )

If the ribbons are flying, that sounds like you got the mix just right.

Sam, sounds like the same stuff I got. It is a barnes product, and I got mine from Arms model It at Kippa Ring.

All ready to go casting and the compressor has either died or it has taken a sickie.
Another delay.

Terry according to what I read it does not need the pressure treatment or vacuum. See the video links Fred posted he just vibrates or taps the moulds

Have a go with one cast ans see what happens, let all know

Sam, been back through the posts and cannot find Fred's video links.

I have put down 4 castings so far. The first I thought was good, the second pretty average, the last 2 never set.

I spoke to Al at Arms model It, and he tells me that cold weather is no good and you should shake the devils out of the containers before you start. It also needs 60 psi to crush the bubbles.
The product that I am using is called 4PU polyurethane resin. It is a part A and part B mixed in equal amounts, color white when set.

But, for now,every thing waits for the compressor to get well again.
Being a woodcarver, the chips are starting to build up and I do not like sweeping.
