Hi folks,
I have a mass produced wood tsuka for a budget katana that I am trying to get to fit the nakago better.
I could fit pieces of popsicle stick wood.
Or I could used Brownell's Accuglas rifle stock bedding compound.
Anyone tried stock bedding compound to make the nakago fit the inletting of the "mass produced" wood tsuka?
(a customization project I am doing...fit the nakago, then put on the samegawa, then the fuchi and kashira, then do the ito wrap...)

Your sword should have improved harmonics and be able to hold tight groups.

Hah hah. I've been wondering this myself. There's no reason why it shouldn't work. Just make darn sure you coat the tang with a release agent. Minwax works well. That is, unless you want the tsuka permanently attached.

Have you considered something similar for improving sword/saya fit? All kidding aside: I have a Musashii Wind with a little play in the tsuka. I've been entertaining some form of bedding--to eliminate this, if it's an over generous slot. I haven't had the sword apart, but the tsuka may also be split. Will glass bedding address this adequately? It can take up voids, mate surfaces, but can it stabilize a split tsuka?

Hi guys, Yes, my katana already has improved group size... :-) The nakago slims down after the habaki. Otherwise a standard tsuka would be ok I think. The cost of Accaglas (gel...get the gel..non-gel Accaglas too soupy/runny) is about $30...ugh! El Cheapo is wood shimming. There is a little vertical play and noticeable horizontal play due to the slim nakago. So wood shimming could get complicated. And the shims need be very carefully done so the blade and tsuka end up aligned. The mass produced, wood tsukas tend to be pre-inletted and come in two halves (one has to split the tsuka wood to inlet it). The two halves are inletted (preferably correctly).
Then the rayskin (I am going to use just a little water-soluble Elmer's Glue (the white stuff for paper...the kids use). Then the fuchi/kashira. Then the ito wrap w/mekuni's. Testing nakago fit at each step. Kind of a rainy day project. Not that we have had any rainy days for some time here in California. RinC

$30 worth would do several tsukas. Compare it to the cost of having a tsuka made to fit.

Alas, no local "made2fit" tsuka places.
But yes, $30 for the kit...makes me wonder if going to the local hardware store and getting epoxy paste would work ok.

Wood shims are the best thing to use for this purpose imho.

Wow my other reply is not here lol. Properly made tsuka, wood shims or replace wood with gun bedding and layer other appropiate materials to replace the other materials in a properly made tsuka. I would hope the gun bedding would handle the forces, but is it designed to only handle certian directional forces or can it also withstand compression forces?

It withstands compression very well. If you mix in some sawdust or metal powder, you have some tough stuff.

I read the excellent and long article on tsuka, etc making. Wow! I am exhausted just reading it. Seems the process is about 1,001 steps. RinC
