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...

    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
    Awesome job. Looks fast!

    Tbh it's quite easy to obtain quartz slab over here and have it cut to size, plus drilling through it is easier than marble or granite

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 was looking at a higher adjustable version but couldn't see how without sacrificing the strength,weight and cost to produce it
    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 ,

    Rusty, these day we are supposed to sensitive and inclusive. A "manhole" cover is now a Personhole cover.

    Right now I'm watching Late Night With David Letterperson!!!

    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.

    Great job UK, love the geometry going on there! Post a video when you get her settled in, love to see how she functions.

    Mark, that is one beautiful design, your double tri-angle with center support is simple (many can create a complex solution but it take a good mind to solve the problem simply) right to the point of solving vibration. I’m really looking forward to a video.
    Also, go for that Arc it is also a great design, you will not be disappointed. They deserve each other.

    Black or red would look good on that drum. Pm me your address and I’ll get you a price with shipping.

    Why thank you , I'm really happy from the response I'm getting for my platform design, Iam going to look into getting an arc soon , as the only hook and ball swivel I've seen available in the UK is by Forza?
