Temporarily Attaching Bamboo

Up to now when making a pipe with bamboo to stummel transition sans spacer, I've temporarily attached the bamboo to the stummel with a tiny drop of CA glue on the face of the bamboo. Once the stummel is ready for stain I carefully break the glue hold and commence. This works well most of the time but on occasion I'll have to reface the bamboo to get rid of the little glue spot and have a gap free fit again.

A question for the group- how do you go guys temporarily attach bamboo to the shank? Is there another method I'm overlooking? Or do you typically finish with your bamboo attached?

Thanks!

I normally use a tiny spit of a drop of CA on the stainless steel, not the face. But only if it is really needed. Most of the time the fit is tight enough to keep the bamboo in place while shaping.

Like Charl friction is normally enough until time comes that it needs to be permanently fixed for the final finish work.

Ok, interesting, just a friction fit works for you guys. I've tried that before and had a problem with the bamboo shifting on occasion, even with a pretty tight mortise-tenon fit.

A bit of shellac will also make a temporary bond which breaks with a little torque. I use this method for heavy filing with my stem shank junctions. Stronger than a friction fit but not a whole lot.

Okay, good to know. Have you noticed any residue left behind that affects the 'flushness' of the fit after you break the bond?

I have not noted a residue, but I have only used this method with flush fit stems, where I have attempted to finish (with stain and shellac) the shank face prior to final shaping.
I think that a couple of swipes with rough sand paper would be appropriate for the surfaces that will be mated with epoxy.

I gotcha, thanks for the tip.

If you use a blob of neat shellac as mentioned it would be removable with some IPA. FWIW superglue can be dissolved with acetone.

Thanks Chris, that's good to know. That could be the solution to the problem.

Shellac removable with beer? I'd rather not waste good stuff!
:wink:

I have discovered that a good Stout works way better than a crappy ol' IPA :lol:
