Thanks Billy,
I take this all in stride now. The Casa Cubana was made by a hand builder in New York pre 1980 and is totally repairable.
I am not complaining but this is a risk that is taken with vintage equipment.
The gell coating for Gon Bops was only on their "Teardrop" line (I believe) and there is external fiberglass base with gell coat over this base. This was done for both the Oak and "Mahogony" lines. This "Teardrop" line is the most durable of all of the Gon Bops line that I am aware of and is the top of the line.
I have both but different combinations of congas of each. I would love to have a "Mahogony" "Teardrop" IQ 9 3/4" and any of the of larger tumbas ITL 12 1/4", ITXL 13 1/4" and ITXXL 14 1/4". I have several Gon Bops but not one ITXXL (must be very rare).
I have several Gon Bops and I have repaired cracks in close to half of them. It is a price I pay for the sound and living in the Chicagoland area. The cold and low humidity really does a number on these congas. I have tokeep my humidifier going or I would have greater problems. I prefer the REMO heads due to their stablitiy in our climate.
I have found REMO heads in odd sizes to fit Gon Bops on the web. It just takes some searching.
I really love Gon Bops, Valje and Resolution vintage equipment. I even like the low end Zim Gar and Playa Azul. I think something happens with the wood as it seaons and settles. I used to be a construction worker and the old timers told me that their tools were more experienced than mine. Well I almost feel that these old congas bring their history and experience with them through the years. I have one wild restoration project I recently purchased off Ebay that was a pair of old tack heads that were converted to hardware back in the day. I even plan to convert some tack heads myself. I plan to convert a 8" x 27" steam bent tackhead into a super duper requinto.
This old stuff can not be reproduced and for a special owner it will give special rewards. (Also some special challenges too)
I strongly suggest gell coating or epoxy finishing for these congas. They will be better preserved by this effort.
Keep it fun.
