Looks like my method is solid. Oddball ones are just leftover parts.

Yes! Great precision and now your process is tuned in. đź‘Ť đź‘Ť đź‘Ť Time to do many more for future pens. Kudos on getting your process down. Thanks for sharing.
 
Looks good Ken. Do you have a proof of concept?? Sure would like to see one turned. Sometimes things do not pan out the way you think when building these. Do you have a kit in mind? People would like to see a finished product to get an idea what they are buying. Just a suggestion.

These will fit any Sierra kit, and yes I'll turn one before I offer them for sale. Stay tuned..
 
I assume those end white pieces are angled toward the center of the blank or else they will turn away. I am sure you thought of that. Will be great to see final turning. thanks.

Everything goes all the way through, so no danger of that.

This might be off-thread, but I have to ask: how do you ensure straight drilling with such intricate blanks? I certainly wouldn't trust the pen jaws on my chuck.

I guess with the precision you've achieved, you can be reasonably sure your blanks are square, so using a drill press with the right vice/jig/fixture would do it. However, I don't have a drill press, nor do I have the space for one, so I'm trying to figure out how I'd get a straight, centered, and concentric hole.

In my opinion, starting with a centering bit is key. I always drill on the lathe, with jobber bits. My blanks are built square with the design centered. Since I started using centering bits, I have had no issues with holes not being straight. Also stay away from brad point bits, they are great with cross grain, not so good with end grain. I should add I use a Nova G3 with Nova pen jaws.

Might try this way. Mark each blank dead center. punch reference hole. Mount blank between center and turn round. Use a collet chuck to hold , the round blank, then use your lathe with drill chuck in tail stock to drill. Man sure you use a center drill bit first before drilling to correct size.

I have use this process for many years and it works to in sure blank will be drilled centered.
 
Ken that came out very well. The color combination helps celebrate the design. Thanks for showing and now people can get to see end result. Hope you sell many of them.

Thank you for this. I've been considering a collet chuck for a while. I'll be doing a farmer's market later this month, and if things go well, that will no definitely be on the list of things to buy with some of the proceeds. I've been wanting to do more segmenting for a while, so this should move me in that direction.
 
two types , one that mounts on threads of Spindle or use the Mt. 2 taper.
I have mt-2 holders for ER 32, 20,16 collets, in Std and MM also have Mt-3 holder for metal lathe. You can find them on Amazon.
