Stacking tubes?

[Woodchipper]

I have an Accord Twist pen kit. For some unknown reason, the tube and finished blank are too short! The kit and tube are no longer available that I could find. Here are the tube spec's= diameter 0.368, length 3.50. Checking the supplier list, I find a lot of tubes, 0.368 but the longest is for the wrench kit at 2.50. I could cut, 3-5/8, and drill a blank, 3/8 bit, but was wondering if I could cut and stack two tubes in the blank. I have a stash of extra tubes JIC. My gun club has an arrow trimmer that would be precise and give a smooth finish.
I can't figure out how a blank and tube could be trimmed to 3-1/6 instead of 3.50! Wrong tube in the kit?
Your advice, experience, expertise is most welcome as always.

I have had success with stacking tubes. But I would try to put the tube joint near the middle of the blank. And use plenty of glue.

The tube seems to be 3/8 inch OD. Most all vendors sell 3/8 tubes in 10" lengths. You can cut the length you need.

I too have had good results using two tubes with the joint at tge middle of the blank. Drill. Glue two tubes i serting one from each end. Trim to correct length

The one time I tried it , about 1/4 inch from the end , it broke when I dropped it on plush carpet . Never again , I said ! . In the middle would be better , if the pen is only for your use , but I wouldn`t sell it . Go with Don`s advice , and get a 10 inch tube .

Thanks. Need to check my tube inventory. I'm a firm believer in keeping a supply as one never knows when an "Oops" happens.
Noticed that some of my kits used the same tube, too.

I've been successful in stacking tubes on occasion, mostly when I was gluing them in with CA (before I started using epoxy) and a tube would seize up part of the way in. My solution was to glue another tube in from the opposite side in order to save the blank. As others have noted, most of the standard tube sizes are available in 10-inch lengths. For those, I cut them a little long as my cutting technique usually damages the end a little, then I bring them to length using my disc sander and my blank squaring jig. - Dave

Found a kit that has a tube of 0.189. Could insert from both ends and trim as egnald states in reply #6.
Will let you know how it turns out.
