I have what I hope is a simple question. I need the pad sizes for a Selmer Signet 100. It looks like all of the upper joint is 9mm but my measurements seem to vary.
So I suppose I'm asking anyone who has repadded a Signet 100.
Is there any data out there regarding pad sizes for various horns?
Ideally I'd have stock of pads and could pick and choose but sadly I don't at the moment and I'm trying to be frugal..

Hi, great question. Call www.jlsmithco.com Ask for the Tech Dept.
I would guess that you might be wrong? 9.5 could be the correct size. the 9 mm size is probably for the octave key. It's been way too long since I've repaired one.
If money is an issue and you have a few weeks to wait, I'll do it for you. It's often not easy to repair and seal horns correctly. N/C if you are a student of really short on cash. $30 for supplies if you can afford it.

I've worked on a lot of clarinets but for some reason this Signet is giving me some grief.
I bit the bullet and ordered a 100 piece assortment. I have around 15 clarinets in the queue (personal collection and for re-sale) so it seemed like a good investment.
I also have 4 alto saxes and an alto clarinet to restore.
I just got my shop up and running (sort of) after moving so I'm just now getting started on my backlog.
I'm thinking I'll reserve 1 of every size to use as a guide going forward.
Figure I should replace the battery in my calipers also..

Do you use a vernier guage to check the cup sizes ?
Remember if using leather pads this is the size you order, but for skin pads the size you order will be slightly larger, typically 0.5 or 1.00 mm, it depends a lot on the exact cup shape.
Ordering one of every size can be wasteful unless you work on Eb, C, Alto and bass clarinets, simple system and German clarinets, and other woodwinds etc.
For the Bb/A Boehm instruments the sizes you need fall into small clusters -
from memory about -
e.g. 8.5/9/9.5/10/10.5 - 11.5/12 - 15/15.5/16/16.5/17
covers 99% of the instruments you are likely to meet.

Selmer lists the pad sizes for a Bundy/Signet as:
1X 9.0
10X 10.0mm
2X 12.0mm
4X 17.0 mm
I'll be glad to email you the .pdf if you send me your email.
My contact is bandtech@windstream.net or info@jbwinds.com

Good luck with your shop! There is always a great need for really good repairmen. If I remember correctly the pads are also on the larger size, the thickness. Hope this helps. Email me if you have questions. savagesax@aol.com

I just went a remeasured the pad cups after putting a new battery in my calipers.
Readings are much more consistent:
Inner / Outer diameters: (rounded to nearest 10th)
Upper Joint:
9.3 / 10.8 (10)
8.5 / 9.7 (1)
Lower Joint:
15.8 / 17.2 (4)
10.8 / 12.2 (2)
So based on that, for felt pads, I think the data from Selmer is correct for this horn: (or close..)
1X 9.0 (Maybe a 9.5?)
10X 10.0mm (Maybe 11?)
2X 12.0mm
4X 17.0 mm
I guess my new question it how to round the measurments, Would a cup measuring 8.5 / 9.7 be better with the specified 9mm or a 9.5 or 10mm?

FWIW: I'm having the same problem. I ordered the Ferees pressed B21 assortment and wish I hadn't (which is not a comment about the quality, just it's usefulness to me.) The music medic assortment looks more useful. I have had good luck with Prestini pressed clarinet pads, but not their woven pads. I'd like to get some from Pisoni aka "Music Center S.P.A".
If I could, I would do the following:
Order these same sizes from about three different companies, mostly in thicknesses of 2.5 and 2.7, and some 3.0.
10 - lots and lots
-
11, 11.5, 12 - at least two for each clarinet
-
about 4 of the following for each clarinet (or two or three consecutive sizes to try based on what you measure)
14.5
15
15.5
16
16.5
17
And one or two cork pads in 9 and 9.5 for each clarinet.
You might need some 8.5, 9, and 9.5, but I think 10 works for most. I find the small keys are easy. The larger the pad cup, the more options you have as far as size - depends on how thick you need them and the shape of the pad. A 17 might fit the cup great, but be too thick, so a 16.5 is a little undersized but not too thick.
I find I need real thin ones for the F# ring key and the 3 ring key
I would like to have some "cushy" pads for the A/D ring key to help with the bridge adjustment.
I don't know what to put on a Buffet for the large pads. I haven't tried 2.5s, but even 2.7s are too thick (for mine anyhow).
I would get mostly "pressed" pads, but not real hard ones. I take it a lot of people use thicker woven pads on student horns, but I don't know how that works - I guess they squish a lot or they use slightly undersized ones for the key cup or something.

Assuming you mean stepped pads, it depends on the specific pad and some other variables. Different pads sometimes have a different shape to the step, so different models might need to be 0.5mm apart to fit the same key cup. e.g. the same back diameter is slightly smaller with a square angle vs. a more gradual taper. It could also depend on how tight inside the pad cup you want the pad. If you want to be able to angle the pad more you might choose a slightly looser fit in a specific situation, etc.
A key cup measuring 8.5/9.7 ID/OD is most likely to need a 9.5mm stepped pad but again it could depend on a few specifics and the variables mentioned. It's much more important not to go by a "recipe" or specs, but to get the best result regardless of specs.

I am fully with clarnibass on this.
The only true test is when you try a pad in the cup
However it is generally better to have a pad a tad smaller than the cup than one that is is a little too big and distorts when pushed in.

I'm with the idea that ' the one that fits best is the right one' idea. That's what I do with sax pads.
I did order an assortment for just that reason, although in speaking with someone with specific experience on this particular model, I also went with his recommendations for sizes. That said, I also re-verified my measurements and confirmed that the information meshed.
I'm cleaning / polishing keys at the moment and once the pads arrive, I'll post an update.
