Aluminum Closed End Sierra

[holmqer]

Have not posted any pen pics in a while, decided I had to do something a bit different!

Closed End Sierra made from Aluminum. No tubes, drilled and reamed to match all the upper barrel and finial dimensions. My first attempt at knurling in 30 years. Did not knurl quite like I expected.

That is very unique. Well done!

NICE! What size drill bit did you use for this??

 

[holmqer]

There are two concentric holes, one is not any standard drill size, it is 3/8" enlarged to 0.391" with a chucking reamer, the other smaller one which grips the transmission as if it was the finial is an "L" bit.

It looks good, looks like you might have not started the knurl with enough pressure, but it still looks cool. I like it.

Wonder how it would look if the kit was a gold Sierra, and you have the Alum gold anodized. Hmmmm

Thanks everyone

Danny - you may be right, I really should have played with this knurling tool a bit before trying it on the pen. It is a scissor style which is different than I used in the past. I think the real trick may be in adjusting the scissor until it knurls a scrap piece of the target diameter just right first.
