I have a Rogers Dyna COB 5 line with two extra holes in it they are approximately 3/16". Anyone have any ideas on how I could repair them?

I have a Rogers Dyna COB 5 line with two extra holes in it they are approximately 3/16". Anyone have any ideas on how I could repair them?

If you are talking of an actual repair method to fill the holes and perfectly match the chrome finish on your snare _ I have NO 'reasonable' ideas _ but if you are talking a way to plug the holes for appearance sake

and aesthetics I have a similar problem.

I have a set of 60's Ludwig Timbales _ each with an assorted variety of mounts on each shell _ that I am going to be working on soon.

So I've been looking into differing rivet designs here.

To fill any empty holes of removed mounts.

I haven't found an absolute best match or method yet _ but I'm thinking something with a small low profile domed head.

Seems like a Stainless domed head might work on your snare _ quickest would be a nice stainless screw with a domed head and a threaded insert inside the shell _ with a lock washer of some sort so it doesn't loosen and rattle on the shell.

Thanks for the idea and link but not quite what I had in mind. To make matters worse these holes are in the lines/grooves that go around the center of the drum. I'm thinking at this point I'm going to experiment with silver solder as used for ***elry creation/repair.

You could really bugger it up by repairing it. Unless the holes are causing a crack, I would leave them.

Yeah- I'm THAT guy!!!

Careful heating the shell. You can discolor the chrome. Read of a recommendation of a chrome polish from a motorcycle shop that removes bluing from exhaust pipes to help with this, but have not tried it myself.

I have read about some low temp solder that lessons that problem.

The only REAL way of doing this would be removing the plating, brazing the holes shut, grinding the area flush and polishing and rechroming. This would be prohibitively expensive and time consuming.

Chrome hole plugs are available, but the smallest Ive seen is 1/4".

Just leave them alone otherwise.

Several months ago, I asked a ***eller if it were possible to fill in what appeared to be a saw cut on a vintage snare stand that I was restoring. I even suggested that he could use an old silver ring I had found on a beach in Mexico for the job. His reply was that solder or even silver would not adhere to the surrounding chrome, thus leaving a gap. I don't know if that is the case or this gentleman was just too busy to even try to take on the job. Just wanted to pass this on.

The chrome would be problematic in making the molten metal adhere. The jooler was not yanking your chain, so to speak.

Again- attempting to repair would not be worthwhile.

To repair holes in brass have to get a person that knows how to do braising they can repair holes for you. Best place that you can go to get this done is a car radiator repair place. After it is done file down to a smooth surface and if you wish re chrome.

Almost to braze to chrome. I contact a company that sells some low temp solder about doing that on some lugs. His advise was forget trying to attach to chrome. Sure the holes are not from a removes badge?
