My bad I should have waited until the design was complete .

As this reminds me of an old saying . "women and children should never see a job half done "

I dont see a problem with running grit side to rubber , many do , as all I will need to do when it gets worn out is turn the worn out rubber off the wheel , re mount wheel in mould , fill mould with rubber , jobs a good one

, I work in an industry that uses Urethane wheels /tyres a lot on concrete ,all weathers , carrying many Tonnes and they are very robust lasting years .
And to get a true profile ( 180 degrees ) for a tube notch of say a 1 inch tube the belt does need some assistance . Then there is the time it takes to cut the notch , say 30s to 60s not long , so I reckon I will get a fair few notches out of a set of guide wheels .
