When Poorboys drill holes ...was: Drilling holes in steel tubing

[wright1902glider]

DONE!!!!

Yep, I finally broke down and drug the table saw up the stairs. Made a
v-block out of a chunk of 2x4 that I salvaged from a dumpster.

Tried the v-block yesterday, and after 2 hours of setup time, finally
got everything aligned and drilled the holes in the bike frame.
Following that I clamped the extra tubes to the frame one at a time,
and used the holes in the frame as a guide to drill through the new
tubes. Did I mention that that also required 2 hours of setup and
alignment time?

Anyway, the tubes are now attached to the bike frame with #12 screws
and it looks pretty good. I decided not to try brazing this time
because the gap in the tube fitup was just too wide. But I will try it
when I make the model airfoils to test in the rig. I found some 3/64"
brass rod that looks promising.

Damn, he's cheaper than I am. I must say, I'm impressed, and that I
will try harder in the future 8*)

Only if he welded a bunch of salvaged and resharpened hacksaw blades
into the band.

BLADE! We don' need no steanking BLADE!

Hmmm...

I've got to cut some 1/2" 4130. (Yes you read that right. 1/2".
Charlie Vogelsong of Dillsburg Aeroplane works is the only place in
America that carries 4130 that thick, it seems.) It's part of a
bellcrank that raises the main gear in a Delta.

The boys have a few bikes that they've outgrown under the house.

How fast would I have to make that blade move?
