<p class="MsoNormal" style="margin:0in 0in 8pt;line-height:115%;font-size:12pt;font-family:"Aptos",sans-serif">Many years ago, I repaired the large cracks in the original steering
wheel of my Phase 1 BJ8 by grinding them out with a Dremel and filling the cracks
with JB weld. After sanding and repainting with epoxy gloss black it looked
great however, after a few years, more cracks appeared at the interface of the
JB Weld and the original plastic from which the rim was molded. Back then I
replaced the original wheel with a shiny new Motolita wood-rim wheel, with
which I was never completely happy, and all was good, sort of.<span></span></p>
<p class="MsoNormal" style="margin:0in 0in 8pt;line-height:115%;font-size:12pt;font-family:"Aptos",sans-serif">I am now faced with having to do the same type of repair on
the original wheel from the BN2 which I am currently restoring.<span></span></p>
<p class="MsoNormal" style="margin:0in 0in 8pt;line-height:115%;font-size:12pt;font-family:"Aptos",sans-serif">Before starting with
the JB Weld process again I thought I should do a little research to see if I could
find a filler material which would form a stronger bond with the plastic rim
material.<span></span></p>
<p class="MsoNormal" style="margin:0in 0in 8pt;line-height:115%;font-size:12pt;font-family:"Aptos",sans-serif">Gemini told me that the rim was made of Bakelite but I was
not convinced. Bakelite is a “thermoset” plastic which, when heated, does not
melt. A simple experiment quickly proved that the rim plastic was a thermo-plastic
material because it easily melted and could be deformed when heated and again
unlike Bakelite it dissolved in acetone.<span></span></p>
<p class="MsoNormal" style="margin:0in 0in 8pt;line-height:115%;font-size:12pt;font-family:"Aptos",sans-serif">I have done some Googling and it seems that it’s very likely
that the plastic used for molding the rims was Tenite™ cellulose acetate. <span></span></p>
<p class="MsoNormal" style="margin:0in 0in 8pt;line-height:115%;font-size:12pt;font-family:"Aptos",sans-serif">Does anyone know for sure what the original steering wheel
rims were made from?<span></span></p>
