Siggy/all

My Hetzer has had little driving  [20 minutes ? ] but the track has already 
had it's first overhaul.
This is what I did
1) new coat of paint  - looking for something more durable on the outside 
so I have tried Hammerite
2  one lose tooth fixed  [ ? ] with glue gun
3) drive rubbers ripped off [ did not follow Steve's advice to the letter 
Doh !]  this prompted the overhaul
    this was fixed by finding some tubing [ polypropylene ? ] that is used 
for routing telephone cables underground this stuff is incredible !
    It is so hard it can be cut on a 10" bench saw and you cannot nail 
through it.
    It is glued to the wooden road wheel with a 2 part epoxy and then for 
the drive I bought 4 vacuum cleaner drive belts [ cost £6.00 for 
4                nearly broke my heart !] and these are glued on with 
contact adhesive , hot glue would not stick to the rubber.
If they show signs of moving then I will drill and nail then.

regards paul
