Hello all,
I have had my current burnishing/scratch pen for donkeys years, probably 30 or more, and its coming to the end of its life, I don't know how it has lasted so long. With this in mind I bought a new one (the red 3 sided type with a crome nozzle), at one of the shows and its rubbish. The problem with it is that the nozzle is 4.85mm and the refills, that seem widely available are 4mm. I find that this causes the refills to waddle about which reduces the performance and sheds far more fibreglass splinters than the old one, resulting in much higher consumption of sellotape to remove it from your fingers! My old one was yellow, eight sided and has the name THOMAS 790 on one side.
Does anyone know where I can obtain a THOMAS 790 (or a handful) before I chuck the red one in the gash bin.
On the subject of the string type, I have wrapped mine tightly with electricians PVC tape, which not only keeps the string in order but greatly redices the pesky splinters.
Regards John J
