Spare brass tube for FORGE CL and FORGE ST pen kits
OD=9.3mm
ID=8.7mm
L=68mm
When you’re a muppet and dawdle just that little bit too long shoving the tube all the way in to your acrylic blank after coating it with CA glue and activator, it pays to be able to get spares so you can retrieve the situation and end up with not one but two pens! The Forge I originally intended to make and a Saturn, that, conveniently, uses the same diameter but shorter tube meaning I could make it from the original botched blank/tube once it was trimmed down to the correct length.
