Liquid metal technology and castable plastics are other fascinating
subjects that are a little bit removed from my former realm of
experience and I am amazed at the applications for these processes.
has cast some finely detailed trigger parts from bronze Ivo and I
wonder: since you are in that business, so to speak, whether you have
explored the lost wax process, using some of the exotics available
through your employment?
By exotics I assume you mean things like zirconia,titanium,etc? All I can say about exotics is that it's a double sided medal...or in other words a very expensive and precise setup(CNC milling units, sintering furnaces, complex vacuum casting processes, special investments)
Don't even bother with the idea of casting titanium.
I have no up-close and personal experience with the process, but I've spoken with those who used this technology and tried introducing it to dental labs for a long time and witnessed how the market turned it down because of the special equipment/materials requirements and overall specificness of the process. But On the other hand it is a marvelous material and if we are to use it......it is best to stick with milling it.
I even know a Russian guy who made a crossbow trigger from one of titanium alloys(similar to the design our friend Kali has).....trigger housing and arrow track base(in form of a pipe) is also made out of titanium. There are alot of pages in Russian, but the pictures give an overall idea of the project progress
As for my part...I cast very small and precise things in various high precious metals/alloys as well as non-precious alloys...can't exactly remember what we use, but it's along the lines of surgical stainless steel. In fact I am currently preparing to cast that aluminum nut along with a new double toothed latch for my brothers crossbow. I will be starting a few new topics both in "Design discussion" and Technology's "Metalworking"I love this stuff
...I've also been researching casting plastics and I'm still waiting for my shipment from smooth-on...Mr SAM(thou he disappeared somewhere) he gave me an idea to test and it has to do with replicating the look of bone and horn, so we might be for a treat on this one, as smooth on has a whole product line directed at taxidermy(horns/bones,teeth, etc replication)
PS: About this type of communication...
I'll tare myself away from work eventually and grab a plane ticket to come to one of Cranequin shoots, If I don't make it there I'll meet up with you guys at Robin's Shop someday.
