    also, lest anyone is in aldi, this is €2.90 a bottle. bought it to soak some of the components (they're too grubby to assess as it is), don't know yet if it's any cop:

    Great to see more people restoring old bikes :D

    Here's a pic of the crack under the bottom bracket, do you think it would be ok to just leave it?

    I still haven't started back working on the bike but I've been out for a good few spins on my new Kelly's road bike and I'm loving it


  • Registered Users, Registered Users 2 Posts: 1,517 ✭✭✭hesker


    Drill a hole where it ends near the middle of the bb. That will stop it moving further. I wouldn’t bother plugging the hole. Let it act as a drain point

    But it might be worth getting a frame builders opinion. Every time you stand on the crank you will be stressing that crack as it’s gone out to the edge.


  • Registered Users, Registered Users 2 Posts: 8,051 ✭✭✭cletus


    @blanchy: the biggest problem you have with repairing that crack is the location. Even a good Tig welder will have difficulty not warping the BB sue to heat, so you could be looking at redrilling, facing and retapping. As it's a steel frame, perhaps a medium term solution would be to drill the hole as hesjer has suggested, and then use some steel putty or similar to fill the crack

    @magicbastarder: dunno where your based, but I'm working in Naas, so if you're anywhere near, I have any of the tools you need for pulling those cranks


  • Moderators, Category Moderators, Arts Moderators, Sports Moderators Posts: 50,212 CMod ✭✭✭✭magicbastarder


    cheers, i'm in dublin so might be a bit of a trek. there's at least one other boardsie near me who *might* have tools.

    that aldi degreaser did an absolutely fine job, btw.
    brakes look well serviceable too:

    where i am currently with mine; was around the folks, got sorted for the socket wrench there and now need a crank puller.
    may bring it around to the LBS; i want to pull the cranks, take out the BB and knock out the headset cups. they'd be able to do all that in five minutes where i'd be trying to bodge something together for a couple of hours.

    525497.jpg

    the worst the rust had been here:

    525498.jpg

    note the nut welded to the right tine. also i've not thought fasr enough ahead about what's involved with removing the chrome (or if it's necessary).

    525499.jpg

    A long screwdriver should be able to tap out the headstock bearing cups. Don't touch the cranks without the proper extractor or it'll end in tears.


  • Moderators, Category Moderators, Arts Moderators, Sports Moderators Posts: 50,212 CMod ✭✭✭✭magicbastarder


    That crankset is shagged anyway. There's damage to two teeth on the middle chainring, looks like a chap stamped steel type. I can't imagine I'll be keeping it, it's definitely not original to the bike.


  • Registered Users Posts: 849 ✭✭✭Blanchy90


    Thanks I'll drill a small hole at the end of the crack to stop it going any further


  • Moderators, Category Moderators, Arts Moderators, Sports Moderators Posts: 50,212 CMod ✭✭✭✭magicbastarder


    i'd been hoping to keep the rear wheel intact - a weinmann rim on a pelissier (never heard of them) hub, but:

    525708.jpg

    i don't think drilling a hole at the end of the crack is the tactic that will work here.
    the front wheel is an unbranded (though i haven't taken off the tyre yet) rim with too much wear on the braking surface, on a maillard hub.

    and i borrowed a crank puller (thanks Weepsie!) and promptly stripped the threads on the drive side.

    That rim looks fubar.

    Re pulling the crank, with the threads stripped, your best bet is heat and a bearing puller

    Ah yeah, it's scrap. It has a future as drinks cans.

    I'd imagine it was a case of round peg square hole. You need an adaptor to go through the square hole and hit the spindle. I usually use a 6 mm nut and bolt with some grease to hold it in place as it's blind once you put the crank puller on.

    If you don't have the adaptor your hit the cranks and it's pulling against itself which ends up stripping the threads out.

    no, i'd say it was a badly adjusted wheel - there was already a spoke broken on it.

    the push rod (for want of a better word) on both tools weepsie lent me fit through the hole in the crank. but the damn things are welded on. thankfully, i didn't strip the threads as completely as i expected, so i'll have another go in the morning. have squirted in some penetrating oil.

    I think the technical term for that is ''f****d''....!


    I might have some usable wheels in the spare parts pile that will suit.

    An old school trick is to use a ball bearing small enough to fit into the square hole of the crank but big enough that it can't be driven into the threaded hole in the bb spindle by the force exerted by the crank puller. Less likely to crush as the head of a bolt might.

    Use a heat gun on the crank arm before removal; the alloy will expand more than the hardened steel of the bb spindle.


    Hairdryer at its highest setting can also work, provided you don't get caught!


    Alternatively pour boilng water on the crank but avoid getting it on the steel spindle...or your leg (speaking from experience lol)


  • Registered Users, Registered Users 2 Posts: 8,051 ✭✭✭cletus


    If it's a steel spindle and aluminium crank, you've more than likely got galvanic corrosion.

    I'd put money on heat being your best friend here


  • Moderators, Category Moderators, Arts Moderators, Sports Moderators Posts: 50,212 CMod ✭✭✭✭magicbastarder


    i was actually about to head back out to have a go of it with the heat gun, would you believe. i also have a bog standard gas torch should i need it.

    certainly looks like it.

    regarding the hubs, cos i want to reuse as much of the bike as possible (bar the horrible chainwheel); is it a stupid idea to buy 36 spoke rims and try to lace them onto the old hub(s) myself? i guess everyone had to start at some time...

    well, brute force and ignorance won in the end; though i reckon i discovered i'd been making a rookie mistake on my first attempt. i was not bracing the crank puller against itself, i was bracing it against the crank.

    Absolutely no way I'd recommend this, been there and ended up in a mess of spokes, nipples, hub, rim and tears!! I felt like Gubnet O Lunacy... I brought the whole sorry mess to Terry in Wexford, yes he did laugh at the Scalder trying to be a wheel builder...

    I'd be of the opposite opinion of CoBo55 above. Give it a shot. The very worst that could happen is you wont succeed, but you'll almost definitely learn something from it

    A good penetrating oil is a must for a project like this. One in a can is much better than any spray. We had 3in1 penetrating and easing oil it was fantastic we never could get it again, Plus gas is very good too.

    I was the same until I gave it a shot. :D

    It looks a hell of a lot easier when looking at videos but what a ball ache. I'd happily pay a wheel builder, I had whip lash going back and forth to videos. I'd say if you did it regularly it would a piece of piss but for a one off wheelset I'd happily pass. :)


  • Moderators, Category Moderators, Arts Moderators, Sports Moderators Posts: 50,212 CMod ✭✭✭✭magicbastarder


    you mean looking backwards and forwards to get the lacing pattern right, before tightening everything up?


  • Registered Users, Registered Users 2 Posts: 6,374 ✭✭✭iwillhtfu

    Yup just following the video I can't recall which one, I always seemed to need a third fourth and fifth hand and then when you have a kind of circular looking thing is when the real fun begins. It's not difficult just really tedious.

    If you had a proper wheel stand,dishing and spoke tensioning gauge it would probably be easier. I jerry rigged the whole lot. :D

    One method is to tape the new rim beside the old one and transfer the spokes one by one. Tension them all evenly to dish the wheel then, when all are attached to the new rim.


    Worth a shot if you want to give it a go.

    Good luck with trying to open 30 year old spoke nipples, seriously Op, take up the kind offer from an earlier poster and get a pair of wheels from him. You'll have enough other problems without taking on a specialized area that will kill off your enthusiasm for the project.

    I've gotten 50 year old nipples to move freely (oooooh matron!) with patience, perseverance, penetrating fluid and copious amounts of swearing :D


    MB, I've a pair of wheels that should do the job; please confirm rear axle spacing, number of rear sprockets and whether she's 700c or 27 & 1/4.

  • Moderators, Category Moderators, Arts Moderators, Sports Moderators Posts: 50,212 CMod ✭✭✭✭magicbastarder


    i had completely forgotten that the dawes i found also had wheels!
    a pair of mismatched rigidas. not sure if they'd be any use to you? i have to check the exact specs on the wheels.

    and when you say getting the nipples to move, you mean they will be bonded to the rim?

    are nipples not easy to get hold of?
    (this is the sort of thing i can get away with asking on the cycling forum)

    i'd be cutting the spokes anyway, the rim is shot and i'd have no intention of reusing spokes which were old enough to consider nirvana as being 'for the young folk'.
    if there was one thing i'd hope so salvage, it'd be the hub and the hub alone. and i've yet to inspect them.

    I've never rebuilt a wheel (or built one for that matter), so this is all conjecture on my behalf, but the nipples bonding to the spokes might be an issue for removal, rather than reuse. I'm not sure that you can cut spokes under tension, the you'd need to back off all thin nipples first

    if there was one thing i'd hope so salvage, it'd be the hub and the hub alone. and i've yet to inspect them.

    Before you dismantle the wheel I'd do the following
    *check lacing pattern on both sides; probably 3 cross but check.
    *measure a ds and a nds spoke
    *figure out how to service that hub, that being serviceable is essential to your wheel project!
    *measure rim erd

    If you don't do the above you'll need very precise hub measurements and have to find a spoke calculator which allows you to determine the exact spoke you need for the rim you choose. All doable but you'll need to be accurate. Maybe check with website linked below

    If you have all the above you can get identical replacement parts, spokes will be easy to get but searching for rim by erd will take a bit of time I would think.

    Once you have all that and are happy you have right components you could giving building a go. Try and borrow the wheel stand, decent spoke key, tensiometer etc, you'll have enough to be doing without messing with bike frame, homemade jigs or whatever. You'll have a much better chance with good tools. The only DIY tool I have is a dishing tool my carpenter BIL made for me.

    Before you do anything read Roger Musson's ebook, it's a brilliant book which take the mystery away from wheels and breaks down what you need to do. Brandt's book is great to, especially at explaining what a bike wheel actually is.

    Take you time, walk away when you get frustrated and enjoy doing it.

    The is a huge tread on bike radar forum I think where Malcolm Borg and an Italian wheelbuilder have made a lot of contributions over the years which might be worth checking out
    Link to Italian man's website here
    https://whosatthewheel.com/2017/11/12/the-bicycle-wheel-basic-dynamics/
    Bikeradar thread here
    https://forum.bikeradar.com/discussion/13020726/handbuilt-wheels-the-big-thread

    If you don't get answers there yacf.co.uk also has at least two regular wheelbuilders who contribute a lot. @Brucey knows a lot about wheels and seems to answers a lot of technical questions (or used to its been a while since I was on there). He claims to have wheels with 80,000 miles and never broken a spoke or needed truing. He places a huge emphasis on stress relieving as do most builders I've read.

    Nice high bar for ya:)

    EDIT I just checked @Brucey is still posting. Count how many times he says stress relieve!

    I'd try the tinfoil first if that doesn't clear the rust the chrome is shot anyway and will need to be redone or painted. You might need to use a few balls of tinfoil but I'd say it'll clean up but the left leg does look pretty bad.

    got the non-drive side of the BB out with less fuss than expected, just waiting for some oil to penetrate the drive side before i tackle it. i would be very surprised if it's italian thread (given it's a british brand) but was just checking - the width of the non-drive side threads is just a shade under 35mm (i assume this is the dimension i should be measuring) which would confirm it's english. i think.

    obviously i have visions of sweating over the frame trying to get the thing out by turning it the wrong way.

    ...the width of the non-drive side threads is just a shade under 35mm (i assume this is the dimension i should be measuring) which would confirm it's english...

    English thread is 1.37" diameter which is about 34.8mm. Chances of a Reynolds 531 Falcon frame not being an English BB thread are miniscule. ;)
