Post Subject: "T" for twoPosted by Paul S on: 12/25/2006
On the cheap:
A few renditions ago you showed a "T" section for the main vertical menber, and this would allow you to use thinner stock without the lateral or torsional issues the nominally-two-dimensional "sail" would otherwise engender. No reason why the reinforcing part couldn't taper as it went up, also, which would blend better with your main "sail".
A la Brancuzzi:
Or, you could use thinner plate in a "sail-shaped" version of the triangular-section vertical you've also shown, by using a longer, wider "section" at the base, then taper down both length and width as you ascend. More welding, but plate could be pretty thin, and it would be LOTS less expensive than any milled versions you've mentioned. Then just weld a thick plate inside the base to tap for threads and through-bolt with tapered flat-head Allen bolts from the underside of a thick base plate. For that last psycho touch, fill it with sand.
Le voila'.
