Well, people swear by the dust extractors, but 99% still means 1% in the air, so I'll have to see. A track saw should make a little less dust in the first place than a table saw. And one of the things I wanted to do was get a fine kerf blade for it to reduce that further (people said I was overthinking the problem wanting a fine kerf blade to cut splines, but if I get one more spline piece per sheet and that much less sawdust that's significant)
The bedroom can be made into a dead-air space because of the way the air con system works - essentially it has its own dedicated unit, with air coming from the bedroom being returned only to the bedroom through ducts. Turn off the one AC and and there's no circulation at all, and nothing from the bedroom to the rest of the apartment.
My only other option is to do cutting out on the balcony. That's viable, as I have had electric plugs installed out there, and have sliding windows so I could get the sheets out and the splines back. In some ways that would be more convenient than the bedroom, but I'll have to be dragging everything in and out each time I want to do any cutting - can't be leaving stuff out there in the salt air, not to mention rain which blows in.
Before I start on the splines, I need to build the cutting table, and so I'll be making a few cuts in dimensional lumber for that, and I'll see how well the extractor works before I really get into spline production.
The simple cyclone over a bucket is supposed to work well. But add a Thein baffle and it gets lots better. There are lots of DIY videos on the web if anyone is interested in that, just search youtube for Thein baffle dust extractor.
I have been looking into buying a hepa filter for the shop vac. It was one of the attractions of the dewalt (vs the more easy to get ridgid line) that dewalt has hepa filters available. Only not. The only merchant on amazon that can ship them to mexico is out with no known restock date (supply chain mess I suppose).
OTOH, according to dewalt, the regular filter traps sawdust, the HEPA is for finer stuff like pollen. So I'll have to see. Trial and error. I could also buy a hose for the shop vac exhaust to run that outside if I open the window, dunno how well that works.
I have a 10' hose on order for the connection between the extractor and the saw, I hope that's enough to provide 8' of movement. If I locate the extractor on a shelf above the middle of the table it should be fine - but that's again assuming inside non-mobile location for the cutting operation.
I'll live, learn and adapt.
Gotta get my van back from the chevy dealer first. They claim the engine light called out the gas evaporation pressure valve. That sounds less expensive than a sensor, so I hope. But there's a long story about the vehicle control computer module. It's flaky, and it somehow flaked out when the service intake person was trying to read the mileage. I didn't see what she saw, but she said it was reading the wrong value (low) - then it corrected? We went back and forth a bit on what it should say, I've driven about 10,000 km since I bought it. Anyway, I didn't see that problem, but on my last trip I did have a problem starting that eventually disappeared, and might implicate the VCM also. I had it into a dealer in Laredo who had the car for 4 days and couldn't find any problem. So I've got some kind of flaky issue, and this dealer is probably going to hold the car for a few days and then give up, unless I just tell them to replace the VCM as a guess. Which I might do. I should post a whole thread on this so car people on the forum can give advice. There's a lot of knowledge here, even if it's off topic for trains.
