my first thought....

bicycle lift



$10. I have one of my kids mountain bikes hanging from one...the bike is proly 30 pounds.

Our ancestors used joints like the ones in the first CAD picture to build much of the town I currently live in. Those buildings are still standing today unless the were destroyed by fire.

Nice. Well balanced.

I've done it both ways; in the attic and along the ceiling; both work. It depends on the pipe diameter. The pipe run through the attic was 8" diameter and would have created an obstruction. However, running 4" diameter pipes along the ceiling didn't seem to interfere with anything

if it helps at all, I quickly drew what I remember it to basically look like.

The joys of having a wife that sews. Custom made aprons that fit and are specific to the tools I carry in them. Pockets below the waist and pencil/ruler/caliper pockets across the chest.

Looks like the toolworks is out of business. The last blog entry is from 2008.

Stretchers




1 1/8” aluminum for the take down connections


Mortised in steel plate and a ½” bolt going through to the tapped aluminum




This creates an incredibly strong joint.
I used some pine boards for a shelf.
