Very cool that you cast the fuse box lid yourself! I think a quick and dirty vacuum pot could be made of a strong paint bucket and a ejector style air fitting. It will obviously not be able to pull down to -0.9 bar or something like that. But I think it would be possible to pull the airbubbles out with less. Might be worth a try. A piece of pipe with ends closed could also be used.
To make a vacuum bottle can I just put the resin filled mold into a sealed container with a spigot attached to a shop vacuum and run the shop vac? I would like to get better results with the clear lids, need to make a couple more for my Moto Morini fuse panel lids.ThanksJim
I definitely think that it is worth a shot. Any vacuum must be better than no vacuum, I would believe that it would take a bit longer to pull out all air bubbles from the mix with a weaker vacuum, but never the less it should help extracting the air. How long is the working time on the resin after mixing? I saw a video on youtube where they are casting a replacement headlight glass for an old 1936 Cadillac and the vacuum pot they are using looks like nothing more than a piece of thick walled pvc pipe (edit: it's a steel pipe) with a thick piece of acrylic on top and sealed by rubber gaskets. I'll try and see if I can find a link. It looks like a doable setup in the home shop. Found it: https://www.youtube.com/watch?v=QMe9MOBjkmcIt goes through all the steps of making the casting, but it is the vacuum pot I thought was interesting. -Ulrik
Hi Jim,Just to follow up on the diy vacuum pot, I just found a video of a guy making one with an old fridge compressor and a kitchen pot. He is able to pull - 0.9 Bar vacuum so it obviously works very well! Just another idea on how to make one. Here's a link https://youtu.be/BeiW_37rS-U-Ulrik

I am showing the Benelli and the Moto Morini 500 in the vintage display at this years International Motorcycle Show when it rolls into town a week from this coming Friday.ThanksJim
My friend who makes resin jewelry places her molds on top of her running clothes dryer to vibrate out the bubbles
