Thread: GIS - Sacramento

Uh, oh... so you can no longer return to Texas, Louisiana or Mexico...

...wait a sec - did you put all of us at Paulina Lake at risk by showing up there?

I hope not, Bob. For all of our sakes....

Or - did you mean my sailing prowess?


Oh... and another touchy topic it might be best to stay away from: you noticed that on Mik's latest adventures... he stayed far away from Oregon? Well... don't ask him why. And, if someone starts in on a tale involving a sheila, a health food store, and some maritime 'art'... well - best just let it rest.

After milling the blank through the thickness planer, the blank measures 45mm x 60mm and weighs 2.8kg (6.2lbs). This is encouraging as the edges have not been rounded-over and the ends have not been shaped/rounded so the final weight should be a little lower. While the final shaping will not significantly reduce the weight, I have come to the conclusion that stiffness is more critical than weight.

I was wrong.

After I rounded-over the edges, shaped the ends a bit, drilled a hole at each end and sanded a bit, the new box boom weighs 2.1kg (4.62lbs). Vertical plane deflection (with 12kg suspended at mid-point) is still 7mm and horizontal plane deflection is still 12mm. Varnishing will add a bit of weight but the finished boom should still be under 2.3kg. I won't be able to varnish any time soon - today's temperatures are in the mid-40s (and the shop isn't heated yet).
