Making big wheels
The disc is made from HDPE 20mm thick.
First cut out the blank, Find were the centre for the wheel is going to be. then mark the position with a pen and centre punch the exact point.
I used some steel builders strap as the holes are punched accurately so the dimensions should be good and the wheel round this is screwed one end at the centre punch mark, using a scriber or anything metal and sharp the circle is marked I find with my eyes the line is hard to see so I go over the line with a permanent marker.

Cutting out the wheel is a long and arduous business but the slower you go the better the final job usually is.

The tyres for this robot are Motocross motorbike front wheel tyres like Saint first they have to be cut in half radially this means you have half the tyre on each wheel. for the new robot the wheels are so large there are no tyres big enough so the tyres are segmented 12 segments for each wheel. a simple clamp helps, don't forget the bead is steel.

the tyre is then bolted to the rim the holes for the bolts are measured out first and the holes drilled. The bolts used are stainless steel hex socket domed head (flanged) 8mm machine screws and Nyloc (flanged) nuts to fit.

But........they're not green!

I have gone over to 500 grade HDPE it is less expensive than UHMWPE or RG2000 I always wanted white but the RG2000 only comes in black and green!
Hope that clears that one up.
I am thinking of calling this robot after a short lived featherweight, Gabriel what do people think?
-
Ok, it was just a joke lol
Is this the fw or hw?
Looks great btw
-
Each wheel weighs over 10Kg Defiantly a heavy. I hope to take it to Colchester for a few test runs.
-
This is so cool please keep putting pictures up and call it Gabriel. I love reading your thread for all the cool ideas.

This is not a trick the clearance from the front of the robot to the ground is 14" or 350mm!

I still have lots to do but I hope to get it going this weekend.:eek:

Looks really cool! And huge too...
Is this going to replace the current Saint or run alongside? Because if it's the latter, I would definitely love to see them both fight each other at some point, maybe with Stinger in there too haha!
-
Wow it's huge! That's awesome! I like the way you've built a bigger version chassis-wise of your feather weight. I was looking at them at Doncaster and all 3 of us rushing to the lexan when Saint was running. They're huge and absolutely frightening in the flesh. Are you having battery packs and everything as your counterweights :)

I love the idea of the whole robot, almost impossible to beat, and the pit can't hold it!
