Workshop Configuration

Renovation Effort

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.

Paint removal

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.

Nick says:

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.

Dan Barlow says:

I tested four different colors of paint in the space with a lead test kit. All tested negative. I verified the validity of the test by swabbing some solder, which turned it red. The large majority of the loose paint was removed by pressure washing, and we will use the peelaway that was provided. After preparation, the walls are being coated with drylok http://www.ugl.com/drylokMasonry/masonryWaterproofer/latex.php and the floor could benefit from coating as well -- considering [epoxy | porch paint | concrete sealer].

Asbestos encapsulation

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.

Nick says:

As far as the asbestos pipe, the best solution I've heard so far from a few sources is to cover it with a plywood sheath. As there will probably be a lot of stuff moving around down there, the odds the pipe will get inadvertently hit are high enough to warrant a more structurally protective solution. The big problem with asbestos is disturbing it, puncturing any sheath we put around it, etc. Given we have the materials to do it (the wood we have left over from the loft).

Safety gear

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.

Electrical Power

Nate says:

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.
