Thorp T18 Plans question

So I'll be reasonable, and avoid the sarcasm, and provide the
dimensions I have - which are not enough for the analysis you plan, but
you can do with them what you will.

The main tube is 1-1/2"OD, .303 wall. The sleeve is 1-1/2" X .120, as
is the cross bar of the this A-Frame. The bolts tieing this into the
longerons are 5/16, and the various fabricated tabs, and wrappers are
..125".

Perhaps you can scale the various lengths off the prints you do have.

You're right about Pazmany at least with regards to deflection. He
spends a lot of time on loads, some on shock absorbers, but little on
deflection. I guess he assumed we'd all taken Strength of Materials,
and Statics.
