Congadelica, what I can see is that you have about 1" 1/2 or about 4 cms.
If you still want this on your Conga ? You will have to re- wet the skin, apply my string technique and if you don't have longer hooks , get yourself a set of this bracket hooks in pic. good to have anyways. With the skin wet place the hoop in the center, then wrap the string around the skin you may have seen pics that Onile posted on another thread, then put on the drum and give yourself about 1/2" of an inch or about 1 1/2 cms. above the rim.
then let dry. What happened is that you cut to close to the hoop, even if you had not had that slight slippage now eventually it would of had happened.
If you decide to do it, just be patient, and I think you can save it.

Marco you will need 6 or 5 depending on how many hooks its requiered to place your head on the drum.

I'm confused...

Is this what you should leave on after trimming? (see quote)

Then, should trimming be done in two stages? (one preliminary, and one final)

Or should trimming be done one time only, after the skin has had a few days to dry and shrink?

Should the trimming be done before, or after the tuning lugs are tightened?

Yeah, I agree with Olsongo, you can probably salvage that skin on that drum. If you resoak it until it is pliable, but not completely coming off the flesh hoop, place it on the drum, pull the skin edges up all around, tie it up using the needle & thread method, and then put the rim on, you can probably get it so there is skin inside the rim all the way around. Then take a pair of long nosed pliers and pull the skin up all around, loosening the hooks, until you have the edge of the skin even all the way around inside the rim. The rim will be up higher than it was, but most people mount the rim too low anyway, and I would guess from your pictures that there is enough skin to have the rim mounted 1/4 to 1/2 inch below the top of the drum, which is fine. I think this all would be easier than trying to remount the skin on a different flesh hoop on a smaller drum. Don't give up yet. You probably won't need to cut any more skin off, try to pull it up evenly all around with the long nosed pliers. Also, you won't be able to judge the sound until the skin is properly mounted, completely dried, and can be tuned up evenly all around. Give it at least a week to dry thoroughly in the area where the skin is doubled over, before you crank it up to normal pitch.

trimming is done in one stage

trimming is done when the skin is still wet, right after you have mounted it

Should the trimming be done before, or after the tuning lugs are tightened?

before, you won't tighten the lugs much until the skin has dried.

The main problem here is too much skin was trimmed. I always trim right at the edge of the crown, I use the crown as the guide of my knife, cutting from the outside with the blade pointed in towards the center of the drum. My freehand pulls the skin tight, I am very careful and steady with the knife hand, there is a chance of knicks if you are not slow and careful.


These being comfort curves, it's my guess it was trimmed with the knife pointed out, cutting along the inside of the curved crown? safer yes, but the trimline was too far below the edge of the crown so when the skin shrunk it went past the fleshhoop.

usually there is plenty of space from the fleshoop below the crown to the top of the crown for the skin to shrink and not go under the crown.

cutting at the edge of the crown, when the skin shrinks it usually only goes 1/8" at most past the top edge, which is fine.

at least this is my way, has always worked fine for me.

Marco here it goes again step by step what I would do.
1. Re- wet the skin, till it's pliable.
2. pull the edges of the skin all the way over the hoop and hold down with a string, by wrapping the string all the way around, side to side, at the end it looks like a pizza.
3. place head with the string on top of the mouth of the drum and place the rim on top.
4. place hooks, and attach to hardware.
5. tighten till the head is higher than the rim, but not flush.
6.cut the excess skin, using the edge of the rim as a guide, that way you would't cut too much.
7. then let dry naturally all the way before tightening all the way.
8. Tune to the desired tone an play on.

I thought it would be rude not to show updated pics of re-mounted Mule .
After leaving to soak for 2 hours it was plyable enough to re mounet , I tied with string al la Olsongos pice on fitting longer hooks . used long noise pliers .

Thanks Olsongo and all who helped through my trauma :p

CD,

I would carefully trim off the pointy bits, as mule dries hard and they will be sharp and pointing upwards

suave

[OLSONGO]

Marco , good deal I am very glad that it worked for you
Yesssss, just be very patient, let that baby dry throughly.
And when you crank it, do it slow and evenly all the way around and I don't think you should have any problems.

PS: Had to save a bongo head last night going from a 9" to a 7" it sure was fun and to bad I can't patent that technique, but I like that " a la Olsongo :laugh:
