Thanks Nick
I had though of the posibilites of different material using this method, it would result in an interesting fly wheel.
This little experiment was a limited sucess. Mounted this wheel up in the lathe this moring I had thought of rigging something up that would drive it on the spokes to trim the hub up, taking the load off the bond, but in the end thought no, may as well give it a good test, cleaned the hubs up no problem the adhesive bond held, with just taking light cuts, drilled and reamed out the bore this went fine, ho ho I thought wer're onto a winner, but when I tried the pully on the crank and gave it a spin it was running out, on closer inspection the bond had failed, the failure was axially not radialy, when I drilled out and reamed, I had the wheel chucked so that axiall loading wasn,t being supported by the step I had turned in the rim, allowing the hib and spokes to move back slightly.

This is what it looks like on a lose assembly.


Not to bad
But as one of the critical features of any wheel on a small engine is that it be woble free.
So to fix it I turned up a mandrel, pushed the hub back so that the area of bond was exposed reaplied more loctite, got it back into position and nudged the rim back concentric with a crude nugger, just a bit of brass bar in the tool post, worked a treat wheel is running dead true again, I'll give it plenty of time to cure before having a think about pinning it.

On the face of it I would think that this is a feasable method for fabricating a fly wheel, but you have to take care on any post fixing machining.
