Repairing a stripped thread on Gretsch Microsensitive

Loading...

So my Gretsch Progressive Jazz Max Roach Snare Drum seemed to have a stripped thread on the Microsensitive strainer where the snare wire threads through and holds wire tension. I thought long about what to do here.....

1) purchase a new upgraded throw-off? True, the modern design is much nicer. But for an est. $95, wouldn't that hurt the originality of the drum? YES! So I moved on.

2) hunt down a replacement strainer altogether. Wella! EBay has one for(gulp!) $190!!!! NOT!

3) a helicoil! Yes! That's the answer. Well, turns out, not for a 4-40 thread.

4) buy the next largest thread(6-32) tap and bore and re-tap. Well, yes, but this is VERY THIN and could crack under that pressure. What then? See possible solution 1 & 2.

Now what?

Enter Loctite Form-a-thread. Relatively inexpensive considering the above options for sure! About $20, but I had to order it.

So how easy was it?

I prepped the hole with alcohol to clean it. Taped off around the hole to minimize any possible product getting on the chrome(notice on the product label - cured product requires sanding to remove. Careful with your chrome!).

I bought an extra long brass 4-40 screw for about $.13 at Ace Hardware to use as the dummy screw. Cleaned it with alcohol also. Apply the Release Agent to the brass screw and set aside.

Mix a small amount of both parts of the epoxy on a piece of cardboard for about a minute. Apply the epoxy to the brass screw and thread into hole. Make sure you go all the way through. I also put a small piece of tape underneath the hole to catch any product.

Let it sit for 5-10 minutes.

Unscrew the brass screw and allow to cure for at least 30-45 minutes(let it go for at least 2-3 hours).

At this point I wiped off any excess and pulled the tape off to reveal the repair.

Now I can just reassemble!

Now I have a strong, like new thread, the original strainer, and the value of this rare gem is in tact.

Thought I'd share.

The completed repair below. Yes, I bought new screws, as the originals were a little wallowed out. I will keep them aside.

Under full tension! Allow to cure at least two hours after removing screw.

Good fix. Thank you. If the screws are too long, they can stop the mechanism from going up all the way: They hit those "blocks" underneath. I've had to shorten screws so that they match the depth of the angled part when screwed in all the way.

True!

The originals are 4-40 x 3/8" long. Just long enogh to be flush when completely installed. Luckily, ACE had the same size, and they were only about $.10/ea.!Excited

Overall, I only need about a drop of the epoxy product. Should another repair come up in the next couple years, I'm covered!

Pretty easy, even for the not-so-mechanically inclined.
