@Ben Stiegler Here are Altman ladders for pipe ends:
This has been a fun discussion to read through. One of the things I enjoy about working with technicians in the entertainment business is our ability to not just answer questions with a yes or no, but to go further and ferret out any potential issues that could arise from implementing our ideas. Most people outside this industry would shake their heads at us and tell that we're over thinking it because it's just a stinking boom base, but to us we see it as both a problem in need of a solution and a solution in need of a problem. If we don't see it that way, someone gets hurt.
On every ballet or other show using boom bases the holes are used to lag bolt them to the deck,as well a spot line dropped from the grid to the top of the tree. I know those in school type places often have “rules” that won’t let you lag into the stage. Their stupid, the deck is wood in viturly all stage decks for a reason, you can screw into it. When the lag hole is abandon it’s easy enough to drill it out and plug it with a wood dowel. Most old stage floors get covered over with Masonite when they get ratty anayway. Replacing Masonite is fast easy and cheep.
Have you considered inserts internally threaded with machine screw threads, externally threaded with coarser threads, designed to get a serious bite into wood yet still be removable with minimal damage. Normally they have a substantial slot cut across one end for driving in and / out. They can be left in place in locations used repeatedly or removed, the remaining hole drilled clean, and a short length of dowel hammered in and held in place with glue for a more permanent repair.If we ever screwed them down, it was just using drywall screws. The purpose wasn't anchor them necessarily, it was just to make sure they didn't get bumped.
Also many theatres don't allow you to use anything but drywall screws into the deck without incurring a fee.
When I read your post about watching Chase MOUNT the urinal; I had to scroll back and shield my eyes. In my mind I was imagining a totally different vision of "MOUNTING".The worst part about watching you mount that urinal is it doesn't appear to be new.
You are correct, it was not new. It had, however, sat outside in the sun and rain at the salvage yard, so I’m 93% sure it wasn’t too gross.The worst part about watching you mount that urinal is it doesn't appear to be new.
