Hi Dawn, is there any chance that you will be making some carbontex drag washers
for the old style Penn Internationals to replace the doughnut drags ?
I would think there is a market for them. there are so many of them out there
and really no replacement parts. the 30 and 50 series really need help.
penn makes you buy all new guts to replace the drag washer.
just a though. thanks AL
I could look into it. Are the fixed to a plate, or free?

I think these are the free donut ones.
yes, free floating doughnut
i could use one too for my old 30...
i was wondering if we couldn't glue two big carbontex washers down to each side of a thick donut spacer, I'm wondering about a a ceramic... or specifically caesar stone... my local granite supplier friend has a cnc cutter... and caesar stone seems like it would be a good material..
am i missing something? barking up the wrong tree?? ;D
That's How great things Happen Eric. Keep barking! ;)
Just joined and looking for a fix as well. Got some off ebay before i was aware of this problem. Seems to be a bunch of them out there for sale. Hope i don't have to turn these into paperweights eventually.
Bula everyone
Ok, I think it's time to re-visit this... especially since I have an old 80 opened up right now.
I have another 30 and 50 of my own that could use the same upgrade.

Here is the "donut" drag washer from an International 80:

and remember these things are very rigid..there is no flex... I'm not sure why it would matter though.
Soooo,
Maybe two laminated sheets can be bonded together back to back and then cut out
or
bond thinner carbontex to each side of a stainless washer...
What do you think Dawn? ... and gang ?
Would 2 pieces of CF material glued to a metal washer work?
That's what I was thinking Lee... OR just 2 thicker laminated sheets bonded together... to make 3.2mm or close
maybe that thickness figure could be flexible, i dunno what the engineering parameters are, but the stock washer is 3.2mm
Do you think it's ok if the "donut" is somewhat flexible or is necessary to maintain the stock rigidity?

You might loose some freespool.
So viewing the picture I see this isn't really going to be a project I can tackle. The CF is 1.25 thick tops. So time and money involved, vs. demand, just not doable, sorry guys!

This subject is popping up on several different threads; might as well post a reply here as well...
Listen, this cannot be the most complicated thing in the world. It is a donut. A flat donut, at that.
Two CFs bonded to something inbetween to an approximate thickness (the 3.2 mm mentioned are likely in reality a nominal 3.175 mm, which happens to be 1/8" which often happens to be the sheet thickness of common friction materials, like Penn used originally.) is not too difficult to achieve.
An exact thickness is likely not necessary. An even 3.0 mm is close enough. Someone mentioned earlier, having 1.4 mm CF sheets. Well there you go- two of those back-to-back = 2.8 mm; pretty close already. If is a matter of keeping the spool centered, poke a 0.4 mm shim in there, and bingo- you're done.
So the question has been raised, what to use to bond it to. Well, almost anything that is flat and bondable, and capable of withstanding a couple of hundred degrees celsius. And preferably somewhat flexible, cheap, easily worked and easily available.
Some suggestions:
Hockey puck: no
Fake marble countertop: no
Sheet of hi-temp / hi-pressure gasket material: yes
Metal: semi-yes (not as easily worked)
Polycarbonate: some, yes
Nitrile rubber: no
Cork / rubber gasket sheet: naw
Hi-temp fiberglass sheet: yes
Aramid paper: yes
Original friction material: yes
Masonite: no
And fwiw there isn't really anything to stop you from bonding it to one or the other side of the existant metal washers.
I drew up a "doughnut" I'm going to send to Erik and it's being cut out of .040 (1.016 mm) SS.
Cool.
These just seemed handy.

What material are they?
Available in a wide range of materials. Usually a blend of kevlar glass or organic fibers with a binder of rubber or ptfe or other similar.
They usually have a consistency similar to thick card stock.
Seriously though, there are at least a kajillion or maybe even more makes and types. Google. Or browse around McMaster-Carr for a while; they give a good basic presentation. Or just trot down to the hardware store and pick something off the shelf, then go home and google it.

Always a pleasure to hear from you Doc. That's solid input ;) Vinaka!

I'd run out to the shed for a thin 4" cutting disc right now...but it's raining about an inch an hour ;D ;D
update:
and Lee, just saw your PM..
I thought it was a coincidence your cutter spelled his name with a K too. ;D ;D
That's great Lee ! Nice! I'll order up some cf sheets and see how we go. You're the man.
