a manhole cover seems a bit overkill. its a tiny little speed bag, not a city bus. How about some nice aluminum plate, plasma cut circular, bevel edge. clear coated or not. all weather. would not have to be that thick, or that heavy.

Originally posted by PunchDrummer View PostI made a number of platforms for myself, and "triangles" (tetrahedron), make the strongest support, virtually eliminating vibration with they're mounted properly to a structure. The problem is that it is more complex to integrate a height-adjustment system without compromising that fantastic multi-point strength. That's really nice, and I hope you produce it for sale and use the strength as a marketing statement. Good job!! I'd buy one to replace my now rotted outdoor platform, but I think it would need a metal drum. Been looking for an iron manhole cover to replace that drum. Sweet!
i also designed a different style of platform using 30mm thick quartz slab that's ideal for outdoor use I'll post a picture of that one too ,

what do you guys think ?
Pics taken today whilst at work ( laid on the floor)
50mm thick hardwood ply , currently getting quotes for real solid wood too

Originally posted by Dutchman View PostMs Deville's husband built several different platforms for their use, Besides wood, he made one out of plate steel, another out of reinforced concrete. There should be photos of them on here plus there are Youtube videos of them in use. A manhole cover is several hundred pounds and in normal use requires two rather strong people to move them around, even with the purpose built pry bars that they use. Depending upon their age they can be made of cast iron, later ones cast steel. The ones at where I work all seem to be cast in India...
