Default Deburring the inside of flanges with the speed deburring tool

So, I was struggling to figure out how to use the speed deburring tool from Aircraft Spruce on the inside flanges of ribs and spar channels. It is difficult to keep a perpendicular angle in tight spaces. Without the perpendicular angle you risk getting an oblong hole instead of a circular one. Came up with the idea of installing the bit into the end of the 90 degree angle attachment (which comes in the Aircraft Spruce RV Tool Kit as well) and hand turning the shafts that would otherwise be inserted into the air drill. This works out really well. Dunno if someone else already posted this idea or not, but it seemed too "Eureka!" not to share.

Similar, but my tip ran in Kitplanes.
Run a 1/4-28 die over the shaft of the 90 degree adapter. Screw the adapter into the speed debur handle. Now you have a 90 degree debur speed tool.

Default Builder's Checklist

We all know how important checklists are before, during and after flights but consider using one for building as well. Start it early. I use one and it's really handy.
All those little (or big) things you have to postpone for whatever reason should be added to the list. Keep it handy in the shop and scratch items off as they get done. You'll sleep better.
Mine is a spreadsheet. I print the latest and write notes on it like date of completion or new items. When I update my builder log, it gets updated too and a new one printed.
Anything works from a chalkboard to a big poster board or spreadsheet. The point is don't assume you can remember all those little things. There's so many of them.

Default Wing skin countersinking

When countersinking the gazillion wing spar rivet holes, dont wear socks with no shoes. And if you do, don't wash the socks with your wife's bra.

RV Beginner Builder Hint #1:
When a small shiny tool rolls out of place on the work table, do NOT reach over lightning-like and move it back by the shiny end. It may be a soldering iron.

RV Beginner Builder Hint #2:
Unusual smells in the shop may include burning skin.
Adendum to #1: don't worry about blowing on the glowing end to cool it off - if your not paying close attention - you might smack yourself in the lip.
it leaves a nasty burn.

If your glove is between the part and the bucking bar, your finger probably is too!

Same for the jeans and tee shirt you were wearing while grinding fiberglass...
