Your point is well made and well taken. After further consideration Ifigured that a rib-a-day would probably be more realistic. Wouldn't want todo a rush job, rush jobs always take twice as long! Just want to setreasonable (but aggressive) schedules and then make every effort to stick tothem.-----Original Message-----

My best intention was to do a set of ribs in two weeks also. The best Idid was 1 rib per day working with aerolite. Lots of small nails etc. Idon't think you want to stress the T-88 glue joints until they are wellset. Realistically, you are likely looking at a month of building. On the upside, when it came to hanging the ribs on the spar, everythingfit exactly. When it came to long bar sanding, there was very littlerequired, maybe 30 minutes per wing. Unless your multiple jigs wereEXACTLY the same, you may pay the time price later.________________________________________________________________________________

About holding all those little nails, OUCH! I found by using a push buttontype electronic probe clip. I could pick up the nail with the clip, positionit and tap it in with out hitting my thick fingers.Tony Bengalis has a cute trick of placing a handful of nails on a tray andtapping the tray while it is slightly inclined. This aligns all the nailshead end down and makes picking them up even easier. Less heads on the wrongend! ;-)John Mc-----Original Message-----
