Originally posted by kenk View PostJust completed the drum and installed on the valor ca-53 platform. The drum weights 61 lbs, is 27" in diameter, 5" thick, and made from fir. The previous factory drum was 23" dia, 2" thick and weighed 23lbs. New drum has six coats of oil clear based polyurethane for protection. Haven't put much time into hitting yet, but initial impressions are that it has excellent rebound, and it looks MASSIVE!...hopefully not too massive.... Will take some video using different size bags for comparison...

Great job on the upgrade.
I'm planing a similar upgrade to a Valor Fitness CA-2, which I plan to purchase soon. My drum will be 27" in diameter and will consist of Santos Mahogany wood, glued up and then cut on end grain, finally re glued and backed with a 1/4" steel plate. Approx weight is estimated to be 85 lbs. From your experience can the frame handle this weight? It will need to be adjusted daily as my son will also train on this and is shorter than me, I'm concerned it may be too much weight for the adjusting mechanism. Thoughts?
Thanks

Good luck making the new drum....post some photos...I believe that the platform will be able to handle the weight...most of the weight is on the screw jack as opposed to the locking screws. I still get some flexing on the frame during hitting...the manufacturer uses plastic bushings in the sleeves that ride along the solid steel rods...I would have preferred using sintered bronze bushings inserts since they won't easily compress like plastic will. Could easily make them if you have access to a lathe. I may do that sometime, but would have to disassemble unit make it happen...best of luck!

The earlier parts of the post show how I made the drum...It was tedious since I did not have access to certain commercial tools that would have made it easier to fabricate. The drum is super solid and looks stunning...the platform that it is attached to is somewhat under-designed and not quite stiff enough to be completely vibration free. I have no plans to build another platform...

The drum is solid and sounds great, but the platform is under-designed and too flimsy. There may be better and stronger adjustable platforms available, but I think you have to look long and hard to sift through the junk before you get well engineered high quality platform...

Platform weight idea
I’m just a beginner working the Bible lessons from the beginning. I put the Everlast adjustable platform up and added two 1”x 24” inch rounds from Home Depot for about $11 ea. Nice but I just received a $20 Everlast double ended bag anchor unit by mail. It’s also about 24” round and holds 50 lbs of sand. I’m going to fill the bladder with sand ($5) at Home Depot and put that on top! Cheap set up but solid so far and guessing about to become really solid!! I’m only practicing an hour to an hour and a half a day but the set up feels good to me so far. I defer to ya’all with reverence.
