I hate a dewalt battery orbital sander. It's hooked up to a dust collection hose that goes to a dust separator, then a shopvac. The shopvac is two prong, no ground.

Every time I sand epoxy, the sander shocks the living shit out of me every 2 or 3 seconds. I also hear it affecting the sander as the RPMs decrease a bit, then ramps back up to full speed every time it shocks me. The shock comes from the speed dial on the sander.

I got some 14g wire and attached it to a bolt in the floor, then wrapped around the outside of the dust collection hose right where it connects to the sander (with an alligator clamp to the hose clamp that holds it on). That didn't change anything, so I wired it up to the ground prong on a 3-prong plug and plugged it in to a wall outlet. That didn't change anything either.

What's the trick to discharging some of the static electricity that this fucking resin builds up? Do I need a bare wire running through the INSIDE of the hose or something?

Any chance the outlet you're using is accidentally wired with reverse polarity (flipped hot/neutral)? Try the sander on a different outlet on a different circuit. If something is miswired upstream on the cirtuit all the downstream outlets can be affected.

Take a multimeter and test the voltage between ground and a metal part on the sander. If it's causing the motor to change RPM this sounds like a more serious problem than static.

No solution here, but your post made me go look for some videos on sanding epoxy that I watched 6+ years ago. Didn't find them, but found a couple "pro" tip videos that were interesting enough to post.

Also, getting shocked when using electric tools should certainly be a bit of red flag.

Mainly using the airgun, constantly, to prevent clogs:

This guy takes it a step further and cleans the table every time too:

Yea that's possible. The guy that wired this place did some weird shit. I'll check that out, thanks.

Also, resin generated a shit ton of static apparently. It used to cause the CNC to shut down until I grounded the spindle.

I think it has to be static. It's strange but there's no way the actual electricity from your shop vac is traveling to your sander and the DC voltage in your sander itself isn't enough to even feel a shock from. The fact that it only happens with the resin points that way too. I think you're barking up the wrong tree looking at your house wiring. Maybe try wearing a grounding strap like people do when working on sensitive electronics?

I am wanting to make a lectern. I plan on carving the legs some - any recommendations on a good wood that looks nice, but can be carved fairly easy?

I always like mahogany in general lol… like for my cube cutting board… stupid AC project took out my garage for wood working.

If you mean you're carving by hand, cherry is a nice wood that carves easily

I really enjoy mechanically complicated joinery. I'm not remotely good enough to execute these in practice, but I'm sloooowly working towards incorporating some of these ideas into my projects.

Dorian Bracht runs an absolutely pornographic YT series titled "Joint Venture" where he goes through different types of Japanese joinery. He's just putting out a book that looks both gorgeous and informative. I'll probably pick up a copy.

Only took two Saturdays. That's a new record for me!

It's a very simple one, but I was using rough cut walnut so it took a long ass time to plane it all.

That last map table I made taught me a shit ton of little tricks, so the doweling and finishing went a whole lot faster on this one. I was worried it wouldn't be stable without some X braces or something, but it feels pretty solid and I assume it won't get abused much when it's behind the couch.

Good job, looks nice

1. Are the legs removable? Looks like you're supporting them with brackets and screws - did you dowel the legs?

2. What finish did you put on it?

I like that idea. Our couch is up against three windows though so would be worried about kids smacking into it and breaking glass. Would help keep our 1-year old from tossing remotes and books behind the couch though....

Nice man! Good work.

They're removable....for now at least. I used dowells and didn't glue them in yet.

It's Rubio monocoat

Cool, seems like a good choice. Making useful stuff that looks nice is rewarding
