Step 4: Assembly.
I marked the legs approx in the middle and drilled small holes to suite the self tappers.
The rim was attached to the legs with self tapping screws, the holes for the spokes can be used but you may need to drill one hole in the rim.
I only had a 20" wheel rim so i needed to give the legs a little bend out to make the incinerator more stable. a larger diameter rim will leave the spread the legs out more and make the base much more stable.
