On Saturday, 20 December 2008, Nate is coordinating an intensive effort to renovate the basement workshop-to-be space. Sign up here for a shift (maximum two people in addition to Nate). If you are wiki-illiterate, just leave a comment somewhere on this page and we'll add you to the table below.
|Time Slot||Helper One||Helper Two|
|10 a.m. to 1 p.m.|
|1 p.m. to 4 p.m.||Ben|
|4 p.m. to 7 p.m.|
The walls are covered in pretty nasty old paint, much of which is already flaking off. We presume at least some layers contain lead. Wirebrushes and scrapers are the preferred tool to remove this without turning it to powder in the process.
- I believe the last, best proposed solution for the lead paint mitigation, based on Martin's experience and some other research that I've seen is to use a chemical peel and paper based solution. This also minimizes the risk to those doing the work and helps enable proper hazmat disposal.
A large steam pipe runs the length of the room, near the ceiling. It is wrapped in mineral wool insulation, presumed to be asbestos. The EPA has changed its tune on this in recent years, and now recommends professional contractors be used for even the most minor of repairs, but I (Nate) am comfortable following the old guidelines, to encapsulate the fibers with latex paint, which is very effective at keeping them from getting into the air.
We have Tyvek bunny-suits, half-mask respirators, goggles, and shoe covers. These should keep most of the nasty off your skin, but plan to go home and shower after your shift anyway. Can't be too careful.
- It appears that all the nearby distribution panels are maxed out and many already host more than their share of double "cheater" breakers, so running new circuits would involve adding a sub-panel off the main, which is relatively distant. This would cost a chunk of change.
- Alternatively, we can try to add outlets in our room that're served by a few neighboring circuits, so we'd be unlikely to blow breakers just by running a few tools at the same time as a dust extractor. This is the low-hanging fruit and seems reasonable. The church has a local electrician who they've worked with before, who only charges $75/hr, who would likely be amenable to letting us do the bulk of the work ourselves and just performing final hookup himself.
- On the plus side, being below grade and having no significant sun exposure, the room stays pretty cool in summer, and Brian doesn't think an air conditioner would be necessary unless we were running some pretty heavy duty equipment down there for long periods.
