Had some home time this evening and made two round blanks to ride in the bead area of tire. The bolt holds them together. The reason I did this is I'm going to use the acetone vapor bath to smooth any lines out. From past experiences in this the bottom always seems to get more of the vapors. As I only have done acetone in bucket ( bottom liquid and soaked towel on top, both techniques) this time I have a electric heat plate to vaporize acetone but still want the ability to invert wheel half way through process. If I knew what I was doing things would not be so stressful as a good bit of time involved in this so far and if I melt it I'll be ,, well we all know how that works!!! Lol!!!
