A large rounded rubber mallet will do the trick, Totally break down the drum, place it bent side down on a towel and slowly hammer the inside of the dented area until it it is repaired. Take it slow, it will work well. And while the drum is broken down you can give it good Dawn bath and bring it back to like new condition.

thanks! I tried that and it worked. The strainer still hits, I wonder if there is some sort of mounting platform missing? A couple of washers work for the time being and it doesnt seem bent.

[COLOR="DarkRed"]I have had this happen on a few vintage chrome snare shells. It's good you got it bent straight again. I would suggest perhaps adding a backing plate to the inside of the shell, holes drilled to match the throwoff. This spreads the tension placed on the shell when the strainer is engaged, so can help prevent the shell from bending again.

Seems like washers or gaskets on the exterior are really the only thing you can do to remedy the situation if it is still hitting, though.

Hi I have an identical drum to yours, lovely isn´t it?

Just one thought from my side: Are you shure the shell is bent so that it isn´t the crimpings for the snare beds that you see as a bent shell? Im asking this because the strainer lever on my drum is also very close to the lugs and i have measured mine for roundness, it was within 0,2 millimeters. Sorry my english isn´t the best but i hope you get what i mean.

That strainer arm looks bent and the strainer is also missing the knurled knob at the top. (Better photos of the strainer might help)

So my guess is the strainer is messed up. It should not hit the lug. (now that the shell is fixed)
