BT, thanks for the info, that’s a positive. Not sure how much different Ryan’s speed controller is than the model I’m using for vacuum and spindle control (I had to get 2):
Immediately after finishing the enclosure I tried using the vac on full and w/ the tight fit everything started to bend inwards and looked like it was going to implode lol. I keep it around 5-6 and I get plenty of suck w/out structural probs.
Jeff, yeah, the gap at the bottom between the center assembly and material will prob be the death of this idea. I agree, brushes prob won’t do much to stop it.
Barry, in the last photos I was cutting parts for a sculpture I installed in Nagoya, Japan last year. I brought them in my luggage instead of clothes. They’re quarter inch birch and 1/8" plexi fastened w/ lots of screws, anchors and spacers. I attached pics. It’s 8ft x 8ft. My machine is only able to cut 34" x 34" so I had to make (9) 30" x 30" templates w/ all the holes for the baseboard. I lined them up, matched the holes in the parts, then drilled through the templates to make the mounting holes in the baseboard. I’m sorry I don’t have the second half of this video, I ‘lost’ my camera on the way home and with it the SD card w/ the images.
In terms of noise reduction for my MPCNC, I bought a 12 pack of 1" Owens Corning 703 Rigid Fiberglass Board (from ATS Acoustics), then wrapped it in fabric, then mounted it to 2" thick R-Tech insulation from Home Depot. It was easier to lay it out upside down (pic below) and build it up, then install it. Super 77 spray adhesive for the fabric wrap and the mount. More glue and deck screws and bolts where it needed reinforcing. My MPCNC is in a corner and I have enough stuff stored under the table so keeping the vac stored behind it and tucked away, helps that noise. I installed a swivel for the vac hose on the top center of the enclosure and another on the center assembly, so I can get full board travel w/out a tangled hose. The hose itself is the stretching variety so getting the length rt (considering it shrinks in size when the vac is on) makes a difference. I only turn it on once the machine starts moving. If I do it while the head is idle, I’ve seen it yank the position from home.
I know I could make big projects easier w/ a 4x8 lowrider but I live/work w/ my dog and have to keep noise down.
