Slow morning this morning, so I decided to add some spacers to the Production Bushfinger. I had previously ordered some green G-10 in .06 in thickness for the project.

Using a set of T10 screwdrivers, I undid the handle screws. Tight, but no lock-tite that I could see. All the fasteners were adjusted during the assembly process and the lengths varied. (This would come into play later when I had to swap screws around to make the combos longer. I also removed a little burr on the short tube-bolt.

From there, I traced the outline of the knife with a sharpie and then cut it out on a bandsaw. Next I drilled the holes and then reassembled the liners on the knife to rough our the shape on my Cheapo 1x30 grinder with a 40 grit belt.

I then worked the top of the handles after I put one of the scales back on. My belt started burning, so I swapped out for a sharper one. G10 was tough stuff. I went to a 120 grit belt and stopped there. I should have hand sanded it further, but I didn't. Maybe I'll take it apart and work that a little bit.

From there, I reassembled the whole knife and then carefully worked it on the 120 grit belt to even the handle with the spine. I could not get into the index finger curve, so I switched to a sanding drum in my drill press.

After that, I hand sanded it through 600 grit. I bought this sandpaper pack with my wood lathe and it's been the bomb having all the grits available in little pieces.

A little rubdown with oil and here are the results:

I did bump the logo with the belt, so I recommend taping up everything, not just the blade.

If you like the fat fiddlebacks, then you will LOVE this mod. It makes the knife feel much like Andy's older handles.

Hope this gives you guys some ideas.

Thanks for sharing. You did a good job!

I was always a bigger fan of the fuller handles that were more common years ago. :)
 
Great work swonut! Thanks for walking us through the process. It's cool seeing the guts as well.
 
Great job Swonut.

So it looks like up to 1/8" combined liner thickness and you can use the stock hardware to bolt it back together

The results speak for themselves.......nicely done !

great job! that's an awesome way to customize a production model. Are they all held together by the handle screws alone or did you also use an glue of some sort in between?
 
Excellent work! Thanks for posting! I too am curious if you used any epoxy or similar.
 
What kind of person modifies a Fiddleback to make it better suit his needs. ;) I like your choice of liner color and the finish work looks great. Well done Swonot!

Did the 600-grit remove the scratches from the tang after sanding the liners down?

I'm not sure what grit FBF finishes with on the spines, but it seemed that the 600 blended everything together nicely. I was very careful to keep the belts and hand sanding parallel to the spine so that all the scratches stayed in alignment.

I also decided to not use glue or epoxy on this one as I am prone to having epoxy go everywhere and coat every tool in my garage when I try to use it as a glue. I thought about using some CA (superglue) but figured I'd give it a run with just the mechanical fasteners for now as I can in theory add epoxy later if needed.
