I went out to the garage to start on the "real plane" now that I'm done with the practice kit, and as often happens with me, I got distracted into another project.  I put away all the tools I still had sitting out so I could arrange the tables end-to-end on the short side, to give me a long surface to work on the longer-than-feet horizontal stabilizer rear spar.

When I put the tables together, the slope of the garage (it slopes towards the door, as most garages do, to let water get out) became more apparent than it was before.  I'm a stickler for little details, and wanted the tables to be level, especially since the next part I'd be working on would span the gap between both table tops.  So I cut some cardboard squares to put under the legs and... well, it quickly became obvious this wasn't the best solution.

Time to go to Home Depot.  I bought some bar steel, some of those "furniture legs" on a 1.5" threaded rod, and a tap-and-die set.  Idea:  create some plates that will fasten to the bottom legs of the table.  Drill and tap threads in the plates, so the adjustable legs will let me level the tables no matter how they are oriented.

Lindsay came out to help.  Here, she's in full safety gear (and a coat and hat, since it was 25 degrees F outside!), drilling the center hole on the steel plate.

After threading the center hole for the furniture legs, and an hour or so later, Lindsay and I made these eight adjustable legs for the workbenches:

Lindsay is righfully proud of her hard work.  She's a great helper!  We'll attach them another day.  Good friends of ours are moving from Texas to Washington State (Soap Lake, in eastern Washington), and we have a going-away party for them tonight.  Sunday I'll be busy helping them pack up their truck, so it will likely be Monday before I get back to this...  I like working for my current employer--we get all banking holidays, so we get Monday off (President's Day).
