How Much brass? Slims are fairly fogiving just adjust the amount you press the tranny in to make up for it if it was on the bottom tube and if on the top you should be fine assuming you didnt clean off 1/2" of brass.
assuming you didn't take like half the blank off....you can just seat the transmission a touch higher (don't push it in as far as normal) and everything will be fine!
I believe I cut off about 1/8 of an inch. I thought my blank was for pencil which is a shorter length. Maybe I should just make a pencil out of it and cut the other end shorter also to make a pencil. sure appreciate all the quick responses.
I am assuming you cut it before you turned the pen. Use the shorter piece for the top of the slim. If it is not long enough to cover the transmission, turn a contrasting material for a wider centerband.
Bruce; You can do either of the options above. Modifying the slimline by changing the length of the upper or lower tube is an easy way to customize the slimline.
You can get 7mm brass tubes in 10" or 12" lengths from several suppliers.
Pencil mechanisms are not forgiving of tube length changes. Pens are very forgiving, you can change the tube lengths greatly and still have a working pen.
