[Closed] New bike build - with a difference. Metalworking content

Brilliant, well done that man, those men. You know what i mean.

10 points each to all concerned....if there are other bits you need, let me know and I'd be happy to donate 🙂

Good show !

Excellent, gets the cynic-al seal of approval.

You should have a logo for this seal: like the British Standards kite mark for bicycle diying? 😉

if there are other bits you need,

I think we're good. We got all the main parts in hand (forks, wheels) before finalising the plan.

Good to see you've got (getting) something sorted. The generosity of people is a great thing.

More progress:

Hey mick, nice work. You doing commissions now ? 🙂

Excellent, would love to build my own frame.

Well done 😉

I have a couple of old wheels if they are any good to you

TJ - thanks but we're covered. It's a long story but its getting two front wheels.

Luckily I got 2 nearly matching new front wheels that take disk and v's.

#Edit - wilburracing - forgot to say Mick cant logon til tomorrow.

Fantastic!

Hello all. Sorry for the delay - must get a password I can remember at home....

No progress yesterday as we had a kid free day out (singlespeed blast around back of Skiddaw). I'll hopefully be snatching bits of metal time after work this week.

Plans now changed slightly as I need to get chainstays (cut down forks) attached before brazing head tube (so I can tweak the head tube height once back end is fixed - mitre directions mean there is no margin for adjustment in the back end). Ronan - I'll drop you a mail to discuss a mod in the chainstay length.

Wilbur - I might be persuaded to make things for friends (and I've just bought £300 of tubes....). This bike is passing on the random mtb kindness of strangers thing after your / Pam's help last new year 🙂

Probably silver soldering seat clamp after work tonight. More pics as things happen.

Good work so far 🙂

I quite like the idea of a carbon fibre spoon as being the opposite of a wooden one.

Time for an update:

Still lots to do - but now it looks like a bike!

Looks awesome

that, and in fact this whole thread, is 100% of OSSUM.

FACT.

Sometimes something comes along that restores your faith in humanity. This is one of those moments.

10/10 so far, great work, faith in humanity restored

OUTSTANDING.
Top work

That is a truly excellent piece of work...

A true example of men in their sheds..

Bravo!

Wicked. I will tell brad as he never comes on here.

If you need some sweet grips or something cool to finish it off, give me a shout. We have a pile of bits for situations like this.

Thanks guys! (and again especially mick!)

Mark - there may be some last minute bits. I'll let you know if needed.

nice, will be interesting to see how the BB is done.

Lovely work! I'm guessing there is going to be some sort of triangulation at the back?

Looks great, well done for stepping up and making something great.

Looks great.

Best thread for ages. Hurrah to the pair of you!

Amazing, it reminds me of a trails bike. I can't wait to see it completed. Good thread.

some sort of triangulation at the back

I believe so - as per the diagram - a seatstay and forward brace.

And yes - it does look a bit like a trials bike! That was one of the ideas from the original thread. Just with 26" wheels and a saddle.

I have been watching micks productions with an interest he's actually quite a talented chap

nice, will be interesting to see how the BB is done.

Its a balance bike

That is Ace - looks not unlike a Trimble.

Brilliant. Good work guys

Hello - thanks for all the encouraging comments.

Just grabbed an hour in garage - front trimmed off main tube, front tube blanking plate shaped and seat tube under-stub trimmed down.

Top tube is half mitred - just got seat tube end to cut. Going with a small diameter 22mm tube - hopefully strong enough....

Nasty seatstays (I hate making them!) will be 19mm. Then maybe a rear disc mount if time available........

Food and painting a wall in the house next. Then maybe a final hour to finish that tube ready for brazing (no gas bottles at home). Eternal balance of family-home-work-biking-bikebuilding-etc

Looks fantastic. Do you have any pictures of your own frame Mick?

Time for another mini - update. No pics this time, but I managed a bit of a fundamental booboo on the forks (: -

I never checked if they were road or mtb disk forks. I just assumed disk = mtb. Doh. Turns out they're too narrow for the tyres we were planning.

But - more good will - Dave at Schwalbe is providing tyres, tubes and rim tape. Fantastic! Of course I've always loved Schwalbe tyres : cause they're the best! And we may have some new brakes on the way too: touch wood.

Also thanks to Chipps for the contacts!

Hopefully Mick will have more photos soon.

Do you need some forks?

I've got a shed full of s*** I'll never need, some old 80mm RS Dukes with borked internals so they no longer boing of any use to you?

Thanks non-cutlery-guy (why oh why did we come up with these usernames). I think we're going the use the forks we have (as they're new) and skinny tyres. But it's up to Mick really. Hopefully he can post up later.

Managed a bit of brazing last night (didn't do a great job but don't think Andrew will notice) then an hour tonight cleaning things up a bit. I'm not loving the looks of the front end but that configuration was a deliberate choice to do a quick job / avoid alignment issues etc.

Side view in approx bike alignment shows top brace tube now stuck in place - 30 degree down slope on main tube and 10 degree on brace tube.

One of Ronan's spare rigid forks should be fine. Its been designed around a 400mm A-C fork so not really suspension friendly - but thanks for the offers.

Davetaylforth was asking about my own bike - so I've indulged in a picture below (first proper showing on singletrack!) 29er with sub 16" chainstays........

And finally a big thanks to our sponsors! Now looks like we have some nice new finishing bits where we would otherwise have been using nasty scrapbin salvage.

Thanks so far to:-
Ronan's pals
The Bike Chain
Chipps at Singletrack
Dave at Schwalbe UK

Also to Craig at Ride On and Amos at Keswick MTBS - they both offered forks etc when I was hunting for donor steel things to chop up.

Tomorrow should be cutting and bending of seatstays!

Drat, clever people, and there I was condratulating myself for changing the stem and bars on the road bike............

OK another quick update.

Much chopping of metal and melting of brass. Seatstays bent, tacked, mitred and now (clumsily) attached.

Shiny new tyre courtesy of Schwalbe - it was just thrown on to check clearances so yes I know it is backwards and logos not aligned with valve....

I must apologise that this bike is getting uglier as the build progresses - I particularly hate the join between the dropouts and seatstays 🙁 But I guess shouldn't forget that this is being built f.o.c. and to a rapidly approaching deadline. Cable guides for rear brake also now stuck in place with silver solder.

All brazing done, just got more work with files and reamers tomorrow night and then get it to powder coaters on tuesday for some RAL4004 (phew).

Finished mass is 5.8 lbs - not too bad considering the main tube is more closely related to exhaust pipe than Reynolds 853.

Looks like complete quality to me

Awesome, I like the Dialled Alpine inspired seat tube brace and integrated seat clamp.

You can't see the detail at the dropout or what they look like before 30 mins with dremel and files......

I guess one part of this build was to give me some extra practice - I wanted to refine my brazing a bit to need less file work / cleanup (and it seemed a more worthwhile use of brass and steel to make another bike rather than just throw dummy joints in the scrap).

I've just found the seatstays a real struggle on everything I've built. The top tends to leave some very localised distortion in the seat tube which needs to be reamed out leaving the tube rather thin - I know I should start using an additional external sleeve or heavily butted seat tube to stop this.

And I find it hard to join large dia stays (these are 19mm) to regular dropouts (esp getting enough heat into the thick dropout without toasting the slotted tube). Next bike will have plate dropouts bent 45 degrees to join the stays in a simple mitre (like on some ti / ali frames). I can also then heat from the back of dropout so the tube is the last bit to get warm.

I guess from these ramblings you can tell it was a frustrating morning 🙂

If Andrew can get rad enough to break it then I think we'll all be really happy!
