Hi Ralph, nice work as usual, you sure keep youself busy :thumbup: , A friend of mine does lost wax casting , he uses liquid silicone rubber to surround the parts, I think he tried the vulcanised method but found this way easier and better results. How do you do the actual casting bit Ralph ? do you just pour it into the moulds like sand casting ?. The reason I am asking is my friens either does centerfudial casting where the mould is held in spinning fixture and soon as the molten metal is in the mould a trigger is pulled and the mould spins flinging the metal into the void, or he also does vacum casting where the flask with the investment plaster is under a vacum while the metal is poured in and its sucked into minor details.
The reason I mention this is you seem to have some defects in the plane baseplate , the stuff I have seen him do is very detailed and they seem to come out as good as the wax was with no defects at all. I can find out more detail if you would like to know Ralph.
Cheers Mick.

Hi Mick. Yes, I do use the centrifuge casting machine. I think that the imperfections here were the result of mold making imperfections. I do believe that I will try the easier liquid silicon rubber mext time. Please stand by; I may need more help as it goes. Actually, things turned out decently well, but still too much finish work to do. Ralph

Hi Ralph , it looks good to me :bow: , I am sure you will be getting stuck into the finishing work as I type :thumbup: . It stands to reason that something can only be as good as the pattern or mould, making and sprueing the waxes is an art in itself I think, so if that one was not 100% in wax it would have them blemishes.
Just give me a shout if you want any more info, my mate does things as a hobby so has found ways of doing things without costing the earth but has learnt the hard way too so might be able to save you some learning the hard way lessons and some tips on the best way he has found to get results. He makes replica Roman items , broaches, buttons, buckles etc so very detailed but also very similar to the items you cast overall really.
Don't forget to have a break for some food once in a while and try to get at least some sleep Ralph :clap:
I am looking forward to the finished thing , Cheers Mick.
