I'm starting to build a HW spinner robot and thought I'll start a build diary.I have no drawings I'm going to make it up as I go along I'm using mobility scooter motors

I urge you to be VERY careful with the spinner. Spinners, along with flippers, are the two easiest ways to kill or injure yourself or someone else. Spinners can project high velocity chunks of metal for surprising distances. When testing it's important to ensure that nothing can escape the test area and that you are protected if something fails

Yes I do have common sense but thank you for your reply

If you are planning to use the 2 halfs of the pneumatic tank as your spinner, as you have on your Facebook page, then I will be running the other way as fast as I can.

Sorry for being blunt but this is not just unsafe but downright dangerous. There is no way you would ever pass a tech check let alone be allowed to spin it up.

While its great to be using things you already have and was very much in the spirit of the original robots on the show, this just isn't safe. At all.

Well for start it's not finished and I can't see a problem after all you weld spikes on to spinners what the difference

You mean it doesn't bother you you that the weapon could break in half along the join and go whizzing across the room and smash into something? Or that since those tanks are probably made of mild steel that 1 good hit will twist them irreparably, ripping itself from its mounts and again breaking free of its mounts.
Also welding your teeth on doesn't work. The forces are too great. Your welds WILL shear. You must dovetail or bolt them in with extra support and even that isn't reliable. If you hit something and they break off those chunks will be going fast enough to kill you if they hit you.

Those tanks are probably C37 or if we're lucky C52 construction "mild" steel with a wall of 3-4mm.

We know that 5mm high grade steel is not enough to protect from the high power spinners in the featherweight class...
