Hola congueros
just thought i'd share some photos of a rough gon bop conga I repaired
rough set of gon bops off of craigslist.jpg
these surfaced on craigslist less than a day after i purchased another pair of gon bops.At $60 I couldn't resist.
many stave separations.jpg
the quinto isn't too bad but this conga was unplayable
many pieces.jpg
no turning back now
clamping jig take 1.jpg
this jig left a few stave gaps near the base

...just a few more

attached some sandpaper to a plywood circle with a backing piece

giving the bearing edge a tune up

my circle cutter

i find the really dry sound of the original bleached cow skin on the quinto quite appealing,so if its not broke why fix it?

Great job...Well Done!

I really like those plywood compression rings. Very innovative!

What kind of router bit do you have on that circle cutter?

FWIW
You might consider fabricating a band for the bottom of that shell.
Due to its location, it is the easiest to trace for a template.
That's where a lot of cracks get started.
I think it is the most important of all the bands.
Even the "naked" GonBops are made with a bottom band.

More FWIW
After I tuned up the bearing edge on a coupla GB restos, I found the curve on the outer edge to be rather sharp.
I made a template from another intact GB bearing edge, lined it with sandpaper and made a very smooth & even reproduction.

Cheers!

As Congalou and you guys, I really dig your skills and courage to go and refurbish/make the tumbadores yourself!
A true inspiration!

Terrific job, congrats!
Definitely a rewarding, if challenging task.
Conga staves are certainly not easy to reassemble I reckon. Respect!

Really nice work and a lot of great ideas for promlem solving [like the jig and the threaded rods for example] I hope I'll remember if I ever face a job like that.

Very cool. 8)

Indeed!
I would strongly advise epoxying the shell exterior.

Very very nice work. Old Gon Bops crack for sure but I think that is because of the type of glue used and the age of the glue. Often repairing one crack stresses the shell and other cracks appear. But what you did, taking all the staves apart and regluing, should solve that problem for a very long time - (I almost said "forever" but that might be too long). Great job!!
