My toxic masculinity can't handle that in my toolbox.

Keep it in a drawer?

It’s the 26.6mm 1-4/64” that’s the problem.
I’d be tempted to try and find a pipe with that as an ID then grind the outside to an edge, it’s a unlikely find though.
Or try a 28mm holesaw -the waste from the inside might be right, how accurate a fit do you think you need?

It's the ID that's the important bit I guess, if that's a snug fit so long as the OD is inside the housing it'll be ok. I measured the rear ​housing at a hair under 27mm, front at 22.5mm.

Setting you up for a gag, but my rear washers are ok, it's the front that are knackered. If I was doing it myself I wouldn't bother with the rear.

Finding a 7/8 punch looks not too hard. Maybe you can even find one to borrow.

Inside diameter of standard 28mm copper pipe is 26.2 🙂 I reckon that would punch through felt if you filed it sharp and hit it hard enough.

The internal diameter should be easy with punches you can get for leatherworking.

Do you think the washers rotate with the axels or the hubs or neither?

If the copper works you could use an end feed fitting for 22mm pipe to punch the OD for your front washers.

🙂

Thanks, that is some good info. There doesn't seem to be a rush on my offer either 😂

A 15mm and 22mm of this for the front?

Get the whole set, then you can make a scale model of a church organ when you’re done.

😝

This looks like a reasonable option for the felt:

And ... they make blue ones tfft 💪

I’d try the 22 copper option first.
There are reaming tools for de-burring cut pipe that you could use to sharpen the fitting and the 28mm pipe - you could play around with chamfering the inside or outside to alter the size.

Or just buy steel punches
😂

You’ll need something odd for the 26.6 mm though.

Ok, now you’re sorted.

What am I going to make these out of?

I need 3 or 4.
I’m not sure how many the double shifters used.

Incidentally if anyone needs any M5x1,0 screws, (Huret and Simplex used this obsolete metric pre ISO size on their shifters and the brazed on shifter bosses are threaded thus) hit me up.
I’m going to be cutting some now my AliExpress tap and die set has arrived.

(I know how incredibly niche this is hence my largesse)

I wonder if something like this might work https://www.ebay.com.au/itm/120865878900

Ah.
No I should have been clearer, they’re like plumbers foible (edit; fibre - but I love Plumbers’ Foible - good pub name) washers but about .5mm thick, they allow controlled slip - so EPDM, which is rubber, is the exact opposite.
I’m guessing that gasket material might work, but my experience with that is a few decades ago - hand cutting a gasket trying to re-fit the cylinder head on a mate’s Austin Ambulance.

Surely you can find red fibre washers in the size you need? I found tiny little ones to fit hub oilers - copied from one of @BigBlock's builds. And I found something off the shelf that's pretty close to my Blumfield front that's rattling around in it at the moment.

What are your washer's measurements?

@absurdbird re freewheels ... I couldn't find this in my watch list the other day

Admittedly it's not exactly cheap, and there is a little rust, but a) it's quite pretty, b) I bet it works well and c) you could have 6 of them for the price of that Campag 50th anniversary one.

OD 27mm
ID 9mm
Thickness .6mm

I think the colour is wrong.
Though Suntour made very good stuff.
Also now I’ve seen the machining and cleanly stamped branding on your 50s Regina Gran Sport Corse, I’ve decided that’s what I must have.
😖😂

The 4 speed helps, more aesthetically please having the first cog in the same plane as the plate! I'm sure I'm telling you stuff you know ... the quality of the Regina freewheels declined over the years but I think 50s/60s and in to 70s they were certainly seen as the best you could get. I never managed to figure out exactly when the Extra was introduced - there are some older Italian catalogues like Holdsworth Aids or Fonteyn or whatever but I've never managed to get a look at them. I spent some evenings Googling it a few years ago and think it was probably 50s but couldn't say for sure.

The Moyne ones are gorgeous and look similarly well made. I've got my eye out for one as my build is Brit with a bit of French.

There’s a 4vit Moyne on eBay at the moment- same seller has a very clean Regina extra in 14/24 I might bid on.
I’m guessing it’s 60s/70s from the typography of the box.

Yeah I saw that. 4 speed and a pretty narrow spread though. So classy putting that nice engraving on the back. You can’t see it, you just know it’s there!

I would agree that Regina is more like 60s or 70s. I don’t think the freewheel design itself changed much, if at all. Maybe quality declined 🤷‍♀️

There was a nos 4 speed one with a red box that looked like the attached (but multispeed) on Ebay for a while a year or so ago. That was sold as 1950s (or maybe seller even said 1940s) but my conclusion was that was 50s. Either way the engraving and everything else apart from the box looked just like the one you’ve got your eye on.
