Hello all,
As to introduce myself to the group I will spin you a yarn as to how I found myself here.
My tale starts a year or so ago learning how to cast using dental plaster for a very large 16 foot long gaming table (Hirst arts molds).
Hundreds of hours and 100 lbs of dental plaster into the project i found this amazing stuff called allumite at the local hobby lobby.
Using permission from Hirst to create my own to speed up the project, Eureka, I was now churning out 9x the amount of tiles I needed at the same time and quicker set times to boot! My sanity was saved
It was finicky stuff, super quick set times etc but it got the job done. Then the use cases started to hit me and got me thinking about being able to duplicate other one-off projects, etc.
A few months later and I've since moved to Smooth-on Products and while I've had great success I still get voids and bubbles etc.
So began my search into pressure and vacuum casting. I picked up a 3CFM pump off of amazon and a chamber/lid from Ebay for what seemed like a good price.
My first test was degassing silicone. It worked great but i didn't use a large enough cup, it nearly overflowed as i scrambled for the shutoff switch. Lesson learned! I've since been degassing my resins and pouring them into the molds I've made however its still not exactly perfect.
So I've done my homework and it looks like what I'd like to try next is a liquid feedthru for my degassed resin. I checked online and all I could find was abbess instruments. I spoke with them but they essentially would not talk to me even though I was interested with buying one of their chambers. I asked if they would sell me a liquid feed thru kit they do-not/would-not sell one. It makes me wonder how they stay in business.
Fast forward to today:
Since all I really need is to modify the lexan lid to my chamber this sound like an easy DIY. Would any of you have a site or guide how to DIY a liquid feed through?
Thoughts? comments?
Thank you for your time...
