so I’ve got a few resin pieces from multimediamayhem and want to put electronics in them. They’re truly great work - just THICK and solid.
Being a newb - what’s the best way to hollow out the insides to allow for lights and such?
I also have a fiberglass shell that’s too thick around the cyclotron lenses - need to seriously thin that out on the inside. It’s about a half inch thick.
So!!! what do I do?
Dremel tool? Drill with some special bit? Chisel and a hammer?
I don’t know much about resin, but I do know you need to be careful, so a hammer and chisel is right out, and I also have had experience with a Dremel recently, and it sucked so much I brought it back. You will be there a long long time if you tried to hollow out a piece by grinding it down with a dremel.
So that leaves drilling. I don’t know how safe it is to drill resin, but MMM told me to drill a small pilot hole before drilling a larger one when I asked about drilling out a smaller piece. With a larger piece, maybe cracking won’t be as much an issue, but I’d still take it REALLY slowly.
They’re pretty pricey but if you need to remove a lot of material, this is what you want to use. I bought one a few years ago and it was well worth it.
You could also use the standard Dremel grinder bits but it will take you twice as long, if not longer.
Hollowing out resin if pretty difficult. Most people I know who want something that’s resin hollow, make a new mold from the resin part, and then just do a slush cast of it. (A new resin part made by pouring resin in th new mold, and moving it around, so it coats the inside of the mold.)
while dremeling…have the vacuum going with a hepa filter…stops all the bad resin from going into your lungs…a mask is the preferred way…I have gotten pretty good with dremeling and holding the hose up close to suck up all the flying dust…Its amazing how little cleanup you have to do later.
So in essence you are recasting someone elses part?
Hollowing out resin parts is not hard but you do need some tools, a Dremel works well with the bit suggested, a drill press with a Forstner bit or even an end mill if you’re careful.
Just be careful when you are removing all that material. I burned up a Dremmel when a bunch of resin ended up getting sucked into the fan, and over time the thing ate itself.
Every time I use my new Dremmel, I stop and use my air compressor to blow it out so that fine particles dont lodge inside and mess it all up.
