BUILD: Hollow Acrylic Prism

I want to do some experiments that involve testing the refraction of various solutions, so I needed a hollow acrylic prism. Rather than buy one I figured why not make one. This was made from a scrap of 1/16th acrylic and solvent welded with Dichloromethane. The plug was made from a standard hockey puck. The video at the end was of the prism filled with plain water but different liquids would produce different results.

That was neat! I love seeing stuff pop up like that - something I wouldn't think to do on my own, but find so fascinating!

[@TabLeft]

Thanks man!

[@RamblingEngineer]

That's rather lovely and it also helped me in how I could best cut acrylic for a project I've been thinking of! Not to mention I think I heard the dark side of the moon at the end... ;)

[@TabLeft]

Thanks for watching =)

[@sunshine5349]

thumbnail was clickbait I thought we were going to see how to make a rainbow logo projection!

[@JackbenchWoodworking]

Another great video, Ray. Looks like this was a 3 beer project...

[@TabLeft]

Aren't they all =)

[@ovalwingnut]

And here I thought you were making a Pink Floyd "Dark Side of the Moon" spinner! I'm going to have to pay more attention in the future..

[@danthemakerman]

Very cool!!! I struggle with drill press shots too.

[@TabLeft]

Dan The Maker Man it's easier when I have the garage door open so I can put the camera way off to the left side. :(

[@mandeepsingh-px3xq]

Hey what's that at 0:33? Is that a way to set the blade at an angle? Also, what's the yellow device at 0:37 called?

[@LivefreeanddiyTv]

That's pretty cool... thanks for sharing 🤓👍

[@TabLeft]

Live Free and DIY thanks for watching!

[@FauntleroyMontgomery]

Use a respirator with DCM bro!!

[@DavidEricPrates]

What was that you used for bonding the plexi??

[@TabLeft]

Called dichloromethane it solvent welds the acrylic together.

[@DavidEricPrates]

I did not know that. That's cool!

[@TabLeft]

Dark Horse Woodworking if you have a TAP plastics where you live you get it there other wise you'll probably have to order it but it's not very expensive (some places regulate it's sale though)

[@86c5corvette]

How strong is the bond using Dichloromethane? I am think about making a new dust cover for an old pioneer turntable I have and using acrylic.Great job by the way.

[@TabLeft]

Thanks! and the bond is great, its actually a true solvent weld and the standard for joining acrylic not just an adhesive, so its functionally one piece of acrylic afterwards. but your cuts have to be precise as it will not fill gaps. its sets firm in a couple minutes but for full strength i think it takes a few days to completely flash off the solvents and cure

[@86c5corvette]

Thanks. I have seen a few KZbinrs use it and I have already bought some just haven't tried it yet.

[@TabLeft]

Charlie Thompson awesome good luck with the project! FYI there is a technique to using the needle applicator too so that it doesn't drip everywhere make sure you practice it on a scrap first :)

[@patriciax5034]

what was the plug for

[@TabLeft]

Patricia x to keep the liquid from falling out

[@KiroHayashi]

I need poor version...I dont have things.

[@maxcohen13]

Good stuff. But as a Minnesotan, I'm deeply offended by your sadistic destruction of a perfectly good hockey puck.

[@TabLeft]

lol, yeah i have a whole bag of them, not a lot of use for them here in California but they are a good source of dense vulcanized rubber =)

[@maryazhar3498]

Its gud but hard.. it's ezy to fail rather to make it..

[@bratuirinel653]

first! cool project!

[@TabLeft]

lol when i first read that i though you were saying it was my first cool project... i was like thanks... i think...

[@bratuirinel653]

TabLeft Workshop 😂 I see what I did there!
