I went to make a Sierra for the first time and it seemed the tube was 10mm so that's what I drilled but it was slightly too small. went and looked it up and found it should have been 27/64". It turns out I had a 27/64" [never used before] so I enlarged it - but I guess cause its more reaming than drilling it caused a lot of friction. Tubes went in fine.
I just wonder why there are pen sizes so close in diameter
"O" and 8mm --- 27/64 and 10mm
