The Colson wheels you linked to on the Banebots site likely wouldn't work with the nut melt method. The bore comes out at ~15.5mm, which doesn't leave enough material for the nut to melt into. I'd second Harry's advice and go for the Bearing Boys wheels. They're very cheap and plenty of stock, with a 12mm bore which is ideal for melting nuts into, and although they're not as grippy as the 'Blue' wheels that used to be sold by Robo Challenge, that can be easily solved by screwing some bike tyre onto them if you find grip to be an issue.
Ok thanks for the advice guys
Soo... reviving this thread...
I am completely lost on imperial measurements.
So on the usual drill gearboxes, as well as on ranglebox neptunes and a few others we have a 3/8 unf thread on the outside.
And a reverse M5 on the inside?
Anybody can tell me why use two systems of measurement?
The video from Ellis that was mentioned at the start of this thread is sadly gone (or really good at hiding).
I did watch the one posted by Jamie on the hex hub adapters.
Anyway... so to put the wheels on it's like this:
1.get 3/8 UNF Nuts.
2.drill holes in the wheels just a bit smaller than the diameter of the nuts from flat side to flat side.
3.Hammer the nuts in or heat them up and melt them in (both seem to work).
4.put a big washer on the shaft.
5.screw the wheel on the shaft.
6.Put another washer onto the M% reverse screw.
7.Screw that one into the inner thread.
Did i get that right? Or is that outdated anyway by now?

Yeah that's the meat and taters of it. There is a YouTube video from John findlay showing how to build a budget feather. In it, he puts a bolt through a wheel and then just traps the bolt in the chuck of the drill. This is how I've done it for ages and it works spot on. I've never put a pic up of it in my thread for fear of being laughed at! At events no one noticed either lol.
There are some tricks to doing it though u need to know if u go down that route.
Has anyone ever seen these in imperial sizes (like, say, 3/8 unf...)?

I've been looking hard for them, for wheels. This is the closest I found: http://www.ebay.co.uk/itm/1621813832...%3AMEBIDX%3AIT
Ooh, shame they aren't ridged to stop them trying to spin round, but they could still work, thanks.
Nothing to stop you scoring them with a grinder or a file and then ramming them into an undersized hole in the wheel.
