  1. steel studs

    After the warpage problems we've had with the theater set walls, we're thinking of doing the next round (fall event) with steel studs. I've watched a few YouTube videos (always dangerous) and it seems fairly straightforward. One concern I have with moveable walls is that since they're not attached to the top and bottom plates, nor end walls, is that they will tilt into a parallelogram. Maybe diagonal corner braces will cure that? None of these walls will be load bearing in the structural sense. Also trying to figure out when you need wood inserts in the vertical studs for attaching doors, windows, etc. Anyone used them and have any words of wisdom?
  2. Didn't the instructions say, "Ground to earth?"
  3. Dye over lacquer

    Lacquer usually contains some alcohol as a co-solvent. If your dye was alcohol soluble, it should have melted into the top coat of lacquer and sort of formed a two-step toner. So I don't believe it will be a problem.
  4. The added advantage is that when I was a software developer, I am sure my mother never understood what I did at my day job. But she could see and appreciate my woodwork.
  5. Back from a couple of hectic weeks. I'm working on the presentation of a day long wood finishing seminar that I'm giving in April. As I do the outline, it occurred to me that most finishing things occur in threes. There are three things that affect how a finish dry or cures. 1. Temperature Some finishes, like waterborne, don't cure well below a critical point (mid 60s for example). The general rule of reactive (Tinkertoy) finishes is that chemical reactions double in speed for every 10 degrees Centigrade (18 Fahrenheit). So a varnish or oil finish will cure about twice as fast at 78 degrees as at 60 degrees. These finishes cure by absorbing oxygen and reacting with it to form polymer chains. For evaporative (spaghetti) finishes, lacquer and shellac, they cure by evaporation of their solvents. Higher temperature means faster evaporation. 2. Air movement Waterborne finishes cure in two stages - evaporation of the water (a thinner) then by the evaporation of the glycol ethers. Varnishes also cure in two stages, first evaporation of the thinner (mineral spirits), then reaction with oxygen. Oils and varnishes then cure by reaction with oxygen. Air movement speeds the evaporation of the mineral spirits, then makes oxygen available. Air movement speeds the evaporation of the solvents in shellac and lacquer. When I'm doing touch up work, I'll usually use a hair dryer to speed the drying of the lacquer (adds both heat and air movement). 3. Humidity High humidity will take longer for the water to evaporate from waterborne finishes. Humidity, I believe, will have minimal effect on varnish and oils. Since mineral spirits and water are not miscible (will not mix with each other) it should not change its evaporation rate. And the cure rate should be irrelevant. Shellac's solvent is alcohol, that is miscible in water (think cocktails or beer) high humidity will slow its evaporation rate Lacquer presents another problem. High humidity can cause lacquer to "blush" -- develop a white, cloudy appearance. Because lacquer dries so fast, high humidity does not allow the water to evaporate out before it cures. The solution to this is to use or add a slower-evaporating lacquer thinner to allow a longer dry time.
  6. Shamrock

    I concur with the start and end with 120. Plywood is already sanded so you are just smoothing it out a bit. Also ease the ages (arisses) as that is a place that the finish will pull away from as it dries and is most likely to wear / impact.
  7. I generally have conflicts first and third Saturdays of every month (during the summer), more conflicts on Saturdays during the school year.
  8. Yeah, at 11:30 pm last week, I cut the miter the wrong direction on a piece (the last piece) of door molding. Filler piece made it work. Can your left hand slap your right hand when it screws up?
  9. PopWood Playback

    Happened to run into the (remaining) Popular Woodworking guys at the local big iron supplier last week. Had a brief lunch with them and they talked about where magazines were going with video content. I see now that they're doing a weekly update with some of their stuff and stuff they've found. Great job to have -- surfing the internet all day looking for woodworking videos, huh? Anyway, here's the current version https://www.popularwoodworking.com/woodworking-blogs/popwood-playback-11-top-woodworking-videos-of-the-week?utm_content=buffer32c6a&utm_medium=social&utm_source=facebook.com&utm_campaign=buffer
  10. We need a bigger shop. Show wrapped up last night. Construction of 10 weeks, 12 late evenings on stage, last piece in place 18 minutes before curtains open. Taken apart, loaded onto 4 truck trips, out the door in less than 2 hours
  11. Use your hands -- help your brain. https://www.cbsnews.com/news/handiwork-how-busy-hands-can-alter-our-brain-chemistry/
  12. Week before, I was about an hour north of New Orleans on a mission trip repairing homes with water/termite/structural damage. Long days there, too.
  13. Glue question

    Me,too. Cures in the bottle, leaves foam blow out, pushes apart joint unless firmly clamped, no gap filling strength, stains skin, ruins clothing, expensive, long cure time, no known solvent for cured glue(must be sanded or cut out), uncured glue can be wiped off with a solvent (that will damage finish if you are repairing a finished piece). IMO, only redeeming quality is water resistance. The bane of my repair business is hearing, "My husband tried to repair this with Gorilla Glue." Immediately at least doubles the time and effort to do the right thing.
  14. Thoughts on a TPW gathering?

    Please PM us or something because I don't regularly visit free-for-all unless I have some spare time.

    I'm in. Couple of hours away.
