SteveG just informed me that he has a Thule carrier, and interestingly the tube is only 1.6mm thick steel, but I would go thicker than that.Quote:

So why not buy the Thule bike rack and adapt it to fit on your spare wheel? What I did, is not the same as what you want, but I had one of those ones that bolt onto your tow bar using your tow ball. Would be about 2" pipe. I cut it to length, welded it to a bit of heavy mild steel angle. Drilled holes in the angle so it could bolt to the studs on the spare. That was done by tapping the threads of the wheel nuts all the way through (I used the security nuts of 2 wheels for this) and shortening the studs so another bolt could be screwed into the end of the wheel nuts with suitable spacers to hold the angle iron that the bike carrier is welded to.
For the non mech eng amongst us SMOA is an acromyn for Second Moment Of Area.
It's often really scary the difference between what is deemed safe and acceptable to an engineer in industry and what is produced and sold at a consumer level.Quote:

If you don't put 4 heavy DH bikes on it and/or drive thousands of km's on corrugated roads the Thule with it's 1.6mm wall will do the job nicely.
What about a different design all together? This type will take the heavy DH bikes no worries and could be whipped up fairly simply. You can get a decent RHS into a hayman reece tow hitch.
