Hi all,
So this is my first non introduction post, but I've gotten a lot of info and ideas reading on here prior so thanks everyone. I need some specific help or ideas for my new setup/creation. So long story short this project has being on going for a couple months now and I finally got it finished and up on the wall. The bad news is any hits to the bag and the whole thing starts vibrating like a tuning fork!! So here's the run down:
I have a 2.75" thick 29" wide octagon hickory and mahogany drum (the wood types alternate each row)
the drum is bolted to a 3/8" thick 29" wide steel octagon plate
The plate is welded to a angle braces of 2" square tube steel that has 3/8" walls (I think I can double check when I get home)
that setup is welded to 1.25" dia pipe that slides over 1" dia pipe for a fully adjustable set up over a 32" range.
The whole platform is anchored to a basement wall via 5/16 lag screws into 2x4's that are drilled and pined into the solid concrete walls.
Also as the picture indicates its a corner mounted system 4 bolts on one wall 4 on the other
So I notice a couple things:
First I'm not a great welder nor my father who helped out so while the welds do their job they don't look pretty but more pressing we got the plate a little too hot so its warped a bit so some of the outside edges don't make contact with the wood drum since the bolts connecting them are in the middle more (Thinking of putting some rubber between them like a gasket to fill these gaps. Would that work?)
Also I've read a lot of the other threads about vibrations but those were all stationary platforms that I could find. And they suggest sand, while I'm not super opposed to it I'd rather not have sand up there for adjusting ease. It already weighs ~60lbs for the drum and another ~60lbs for the steel plate plus all the square tube so adjusting becomes a work out itself already lol.
As for the vibrations with just a hand test and being able to actually see it moving, its really bad on the platform (I read a thread with a water cup test, my cup would jump off the platform if I did it), if I move my hand to the slide poles it dampens severely, the guide poles that don't move I can barely feel it if at all, and then the wall/ anchor points I cant feel it at all.
I do know that if someone either pulls down or pushes up on the platform while another is bagging like you see in pro boxers open workouts leading up to fights (generally some huge body guard lol) helps the vibrating immensely
Any ideas, suggestions, ect on what I can do?
Thanks (hopefully photos work)
