If you're casting it solid, that may end up a bit heavy on the helmet, wouldn't you think? And why didn't you use the algenate?.. it's a simple water based mix, sets up quick, easy to vibrate out bubbles, virtually fool proof in my opinion and it's much cheaper to use than the commercial silicon mold compounds.
Hi Frank. I was going to cast solid but use aluminum, I had done a sand cast of the ball final and dome last year and the weight was OK compared to the original brass ones, I am open to suggestions tho
The silicone mold that I'd used was made last November and I didn't use enough curing agent so it didn't set properly so I set it aside, I was then was going to make another, then you suggested alginate, so I ordered 4 KGS, it arrived about three weeks ago but work and life stepped in so it had to wait. So three days ago I was going to make a alginate mold when I picked up the silcone mold and it had set, only took two effin months . I then decided for now to try the silicone mold, and if it had turned out to be no good I would then do and alginate mold.
I actually have another job to do using the alginate which I hope to start soon. I've had a long day at work, had dinner and a few nerve settling ales and now its shut eye time, I'm beat
