I guess I would have a punch cutter though #assets

How would I go about getting the right size punch cutter? The company I'm speaking to doesn't have it so needs to make one - £32 each for front and back. If I got the material and did it myself I wouldn't have any more to sell to try and spread the tooling cost :)

Would be a medium density wool felt. My measurements of the thickness of the originals is 1/8" for rear and 1/16" for the front, I might struggle to get that but 3mm and 1.5mm are possible.

These are the measurements I've taken:

• front OD 7/8" (or 22.2mm), ID 19/32" (or 15.1mm) , thickness 1/16" (or 1.6mm)
  
• rear OD 67/64" (or 26.6mm), ID 21/32" (or 16.7mm), thickness 1/8" (or 3.2mm)
  
  

The ID is right on the OD of the cones, I think this is ok, I can't imagine there will be much friction, especially after a few turns of a greased axle. They are supposed to be dust seals after all.

Blumfield Hub - felt washers for dust seals

I'm thinking about having some re-made. [I did try myself with a bit of felt but there was fluff everywhere. I have also tried the red fibre washers plumbers use - not many options in old imperial sizes, that are themselves pretty bespoke to Blumfield as far as I can see, and they are hard and rattly.]

The tooling and minimum order is quite $$ though, so would need to shift a fair few to others.

Would there be any interest here in new felt washers, 2 x front + 2 x rear? Something like £10 for one set, £15 for 2, £20 for 3?

If anyone's going to want these it's peeps in this forum!

Only the English for me so far. I am keen to try the one in Tuscany, that looks pretty pretty nice. I need to finish the unwanted build for my wife first though, don't think I can swing Tuscany by myself.

Edit - unwanted by her that is, I'm having a great time building it :)

Can't remember if that's May 54 or 55 Apr, let's go with 54. That's the PC front plate though.

N.B. one nice thing about the Cyclo freewheels is they have a notch in the rear of the body so you can get the final sprocket off (relatively) easily.

I think I rode Eroica with a 42 x 24 bottom gear (and realised what a weakling I am).

💪

I did enjoy that.

That is an ambitious price. I just searched for Campagnolo 50th Anniversary freewheel thinking that seller was nuts, but it's the world that's nuts!

I'll admit this is a nice looking freewheel but how many euros a ride do you think an alloy one works out at?!

Thanks. The earlier ones have a year stamp on the back (not sure if always but definitely some do). I have one with a 54 on it.

To get the rear sprockets I want I was thinking of building my own with a Regina body - that's your option that hasn't change significantly has lots of availability. The "regina gran sport corse" engraved ones are PC or pretty close afaik. I guess the Extra sprockets will fit but that's a guess.

I'm going for 44/50 on the front I think, got a 44 and 45 inner ring for a TA double adapter. Personally I'd like a 26 if possible :D Which is the biggest the TdF is supposed to take, but clubman has already advised that will be a stretch. So think it'll be 14/24 if I can find it, think I've got a Type B 14/22 stashed somewhere.

The Simplex pages in the 1950 Fonteyn catalogue show a Simplex branded freewheel, but I haven't figured out how to tell if they're PC. The freewheels it lists are "Eureka" I don't know if that's the brand or the Simplex model name, it's hard to tell in the older catalogues.

Ones like this come up https://www.ebay.com/itm/NOS-1970s-SIMPLEX-VINTAGE-BICYCLE-FREEWHEEL-BODY/293534527560?hash=item4458057048:g:A3kAAOSwvuxehybJ, I've seen described as 1950s-1970s so who knows, but they look fitting.

Moyne is another option, can be reasonable can be $$ depending on who is selling and they also look great imo https://www.ebay.com/itm/J-Moyne-4-Speed-Freewheel-1940s-50s-for-vintage-531-Campag-Simplex/184699475325
[For a 16-22 spread though kinda think just go for a 16 fixed!]

I've been trying to figure this one out myself if you hadn't noticed. I keep thinking something like a Suntour Perfect would be the best option and screw the PC.

Not sure exactly when Cyclo Type B freewheels first hit the scene but that would be good for 1952 and they do come up on Ebay every now and then. Catalogue page is from 1950 Cyclo catalogue in the VCC - yes you really should join :) You won't find a 24, @clubman will tell you that's for wimps anyway.

@clubman I guess the forks are beyond salvaging? Sure you would have mentioned it if they were, I know you said getting the stem out was destructive, but was that to the blades as well as the steerer/column?

I think given previous comments I needn’t have bothered, but meh, everything else was all fancy thought I might as well have a smooth headset. The indexing dents I guess we’re a 5/10 on the severity scale, and they weren’t deep enough to require hard chroming. Just grinding and decorative chrome.

This was the company that did a couple of crown races for me https://www.universalgrinding.co.uk
I had to continually chase for months both times, although to be fair the second time there was some sort of global health pandemic going on. Like I said, I think it was just a small annoying job amongst other stuff. They did a really good job though. As far as I know ‘hard chroming’ (which they offer) would give you a good bearing surface after grinding.

I do like those Mansfield saddles, being tempted for my ROH ‘Lyta’ build. I guess they ripped of Ideale? Bit more gritty though :)

This was a good read https://farehamwheelers.com/wp-content/uploads/2020/01/Racing-in-the-40s-and-50s.pdf

Wow

I feel like I’m an agent for Hilary Stone with no commission, might be a hint that I’ve spent way too long on his website ... https://www.hilarystone.com/Chainsets%20single.html

I love that chainring.

That’s great, thank you. Good tip turning the cups.

I can’t remember exactly what the machine shop needs but pretty sure it’s an annular something or other. Not a huge surprise! Didn’t seem like many places have one when I was looking.

As far as I know lightly refacing would be fine, I think the metal under the bearing surface is softer though isn’t it? That was the question with mine - could it just be re-faced or would it need hard chroming as well. Starts to get a bit pricey!

Please put my name down for one of your tools!

@Nbenja3 re Duprat hollow cranks ... here you go, lovely crankset https://www.ebay.co.uk/itm/Vintage-Bicycle-Rare-Duprat-Crankset-Hollow-Arms-1930s-1940s-1950s/224378664050

@clubman re indexed headsets ... I've been meaning to ask, how bad does it have to be before it's noticeably notchy? Totally agree that ~ 50% of headsets I get my hands on are at least slightly indexed in the lower races. I should try one and see how it feels, never really fancy fitting and removing a headset (in a nice frame) for laughs though.

I have had a couple of crown races ground at a machine shop and they did a great job. Took ages though, almost like a £30 job was a bit of a faff :)

Edit - should have said clubman or anyone else :)

@SideshowBob I saw that, how cool is that?! Almost worth having another kid.

The TA pro vis seemed too easy. I can't claim the Carmina as my own idea, that was straight from those Alex Singer bikes. I like it though, echoes of period stuff, cranks are a bit chunky. I ordered silver SRAM levers but they were black when they arrived, discontinued long ago apparently, just a dodgy ebay seller with the wrong pics. I stripped the ano and polished them. The gum coloured Hudz hoods are discontinued too, I've stashed another set. I haven't checked recently but a lot of the components on the Singer bikes was ~ 2000, from bitd when it was still polished alloy. Jeez, 2000, bitd.
