This is excellent. I have decades experience with lost wax and centrifugal casting and have evaluated Polymaker filament designed for casting. Unfortunately the filament is designed for really high burnout temperatures, and PLA works better at lower temperatures. So your discovery is highly...

Hi Mike, Please find attached a copy of my Powder Coating lecture given at MMEE. Although I do have the copyright to this presentation, Im happy to have it shared with anyone for personal non commercial use. It is such an accessible technology with such rewarding results, that I can imagine...

Hello Mike. All of the material in my lecture originally appeared in my article in Model Engineers Workshop August 2019. The article had the same title of " Powder Coating in the Home Workshop" The photos and diagrams were mostly the same although I did cull some for the Powerepoint. If...

Hello Mike. Thanks for the kind words regarding my presentation on Powder Coating at MMEE last Saturday. I am happy to email copies of pertinent slides if people contact me. The venue was not good acoustically. My wife and I spent the 30 minutes before lecture time trying to tune and...

Brilliant topic! I am basically a chaotic organizer ( my wife says non-organizer.) My shop is 8 x 12 and is part of my double car garage which has never housed cars. The shop is highly insulated and is for clean work only. Grinding, sanding, finishing takes place outside the enclosed shop in the...

The reason for using cristobolite based investment is that it is rigid as well as porous. Burnout leaves the cavity void. However a high temp burnout of 1000 degrees F is needed to completely clear the mould of wax. If you just melt it out at low temperature the porosity is "clogged", and the...
