Best bit for drilling acryllic pockets

[jtclose (Jim Close)]

Would acetone remove milling marks ? I always wanted to cut a cube of acrylic into something but I never found a way to clear the surface.

Yes. They need to be relatively flat & smooth to start with. i.e. sand down to at least 220 grit if necessary. Super light application. You don’t want it dripping. Let it completely evaporate & reharden. Additional applications if necessary. It takes some patience, for sure. (and a very clean environment, like a paint booth)

It is hard and unforgiving but that’s not a bad first try at all.
If you don’t like the glue process, maybe there’s a world where you still cut the channels for alignment but you just polish them and use brass threaded inserts for final assembly
You’d have to be creative with it to make it look nice and I’m not sure what fewer fastening points would do to the acoustics but it might be worth modeling up if you’re still looking to produce more.

I’d still love to hear your thoughts on the acoustic performance of the acrylic vs mdf if you do load the electronics into it

Thanks. I am going to replace two of the acryllic plates that were “too aesthetically compromised for my taste” and hopefully do the final assembly with the acrifix 0192. Using acetone might not be the best for a speaker that basically includes a subwoofer section. When done, I can tell you about the audio experience (but my expectations are good).
