Interesting thread! Most leather shops have a punch that could probably make these for way cheaper and that's basically using the scraps they have laying around. Basically they are premium cow hide right? I wonder if they are treated with any type of solution to give they some type of anti slip quality? Is the sound of the drum actually improved by these and would it be significant to the naked ear? Is the principal mainly to stop detuning? It looks like there are two leather washers sandwiched in between the traditional flat steel washer. Any ideas on the thickness? 1/8th maybe?I'm gonna give this a try!!!thanks for the info!!
I keep forgetting to check 'email notification' when I post.
I've been happily using the Canopus washers. I contacted Brady Drums here in Australia and they quoted me 50c per washer - roughly the same as getting Canopus sent to me from the US, but I tried to place an order with no response.
USE:
They do slow the effect of tension rod loosening, but it's not a guarantee. I still have to tighten the rim shot lug every couple of songs/end of set - both modern and vintage snares. I do, however, like the give - or suspension - it creates, which may focus the sound and provide some punch. I can also tune lower without 'rod rattle' - I love fat snare sounds.
On one snare (1971 Supra) I have found it can soften the sound too much, hindering projection. That was with some very light hoops, however.
Definitely worth checking out. Five of my snares are fitted.
