Looking for some advice here....I recently acquired a sonor lite shell set with intent on converting it into a small jazz kit - 12,14,18. The 18x18 tom was described as having ~3 inch crack only affecting the inner veneer so I figured it would be simple to cut the shell down to 18x14 for use as a bass drum. 
 
Now that I've received the drum, the crack is actually about 7 inches long and is deeper than just the veneer although I cant say if the crack is that deep all the way in. For those of you with restoration experience, is this shell shot or might it do ok with gluing down the crack? 
 
I suppose I could cut it down to 18x10, but that's really not what I am hoping for. Thoughts? Thanks!

That shell took a serious impact, right on the edge. All the plies are cracked, right up to the wrap, if you look closely. It can be repaired with some injected glue and a lot of clamping, but the shell is no longer perfectly round in that area. It won't be right.

Try cutting it to an 18x12 and see if that removes the worst of it.

 

12" deep basses were an option in the 50's and 60's, even up to 22" drum diameters.

 

 

By the way, whoever sold it to you and described it that way is either blind or a liar.

Yes, Dan that shell is cracked all the way through. Some fiberglass resin and a syringe would fix the crack, but unless you make some precise clamping jigs  to hold the shape you will probably never get the shell to stay round.

It looks like it took a serious fall. I unfortunately had this happen to me on a six ply shell. Destroyed the hoop. But my father, who is a master woodworker, made jigs to fit the shape of the original, injected glue in the crack and clamped it. New hoop and the drum is great. Too bad the seller wasnt honest about the damage.

It may have taken an impact in shipping, worsening the original area. That would be an unlikely coincidence, though.

As others have said, a round form should be made to hold

 

the shell to the correct shape while the glues sets.

 

Try the clamping system before applying any glue.

 

 

For glue, I would suggest using urathane glue

 

and apply it with a needle and syringe.

 

Also, have a spare piece of veneer around to push the glue under the

 

veneers of the shell. Maple veneer tends to be the thickest.

 

If you are not used to urathane type glues, know that they expand and foam up.

Consider wearing vinyl gloves when doing this.

I would force glue into crack, clamp it with C clamps till dry.   the early Ludwig had scarf joints, no way were they perfect circles, most had a hump on the outside of shell.
