HI Arle, Thanks for the quick reply. I should have been more specific with my query. My curiosity involves cast wheels made of some material that is molded and hardens into a solid. Yes I know the maker who uses MDF and have played one of his instruments and enjoyed it quite well. But this is not the route we are looking at going in. We have a great plug that was done by rappid prototyping and we want to cast it in somthing that will render a great wheel. It cannot be brittle or too soft as you mention. I wonder what would be the best material to use in this application. What are the great builders using?
PS Just repaired one of Nagy's tekeros for a customer. BIG sound and BBBUUUZZZZZZZ, Rather enjoyed it. What's comming in your neck of the woods that is HG related?

There are makers using resin wheels and makers using composite materials (MDF), so there are at least two materials I would call synthetics, but I suspect some would consider MDF an engineered wood product rather than a synthetic (I guess it would depend on what the binders in MDF are, which I don't know). But even within resins there are literally hundreds of varieties with different strengths, brittleness ratings, flexibilities etc. My guess is that for a HG wheel you couldn't use the softer resins (since they wouldn't scrape as well) and that you'd have to use the harder resins, which is what would make them somewhat brittle. If I were building an instrument now, I think I'd look at MDF. At least one maker I know likes MDF so well he uses it exclusively: there's no worry about tear-out while fabricating the wheel and it's dimensionally stable while still retaining a good crush resistance and isn't brittle at all. It's also inexpensive and generally easy to work with. He doesn't even band it as there is no need to do so: it holds a good surface without any need for banding. -Arle On Mar 30, 2010, at 12:48 PM, Melvin Dorries wrote: Really interested in this brittleness aspect and am wondering what material is a good synthetic wheel made of? Does it get brittle over time as it ages? Do all builders use the same material or what? Thanks Mel -- You received this message because you are subscribed to the Google Groups "hurdygurdy" group.
