M_V's multitude of bikes and adventures in the land of framebuilding

That was the plan....😕

The joint should be in compression mostly and you can silver braze a lugged game together...

It'll be fine...

lugs mean more area the silver can stick to, i think. should ask a builder before attacking the forks, imo. i'm all for diy but braking is serious business..

Yeah you might be right.

could you do braze it in brass and put a fillet on it? Would be stronger but don't know if mapp gets hot enough

Not sure I know what you mean?

A fillet with brass is an external join like you'd do with silicone on the edge of bath/tile.

I think you need a brass rods and different flux to silver but look it up.
I don't think you can really do it with mapp as you need a lot of heat, it's mapp you're using?

Ah ok I'm with you.

Yeah Mapp, though I have just looked at oxy acetylene stuff on eBay and torches, hoses etc aren't as expensive as I though so...

I've always chucked enough brazing rod at things that there's been an external build up of the brazing medium, would that count as a fillet?

Like in this pic,

brill that's def fillets, very impressive btw.
If you have any scrap you could have a go at some destructive testing to see how much abuse your joints can take, should reassure re the disc tab.
You've got me interested again in giving this a go.

Haha, awesome, cheers. Meant to just braze, accidentally fillet brazed!

You should, a Mapp torch cost bugger all. The biggest expense is probably the rods.

So I asked about silver brazing a disc tab on facebook and (Super)Ted and a guy I know that works at Shand both reckoned silver might be a bit weak and that I should use brass but that Mapp won't cut it for brass.

As I said above, I'm thinking about upgrading to Oxy acetylene Propane (its cheaper) but that's a while off so in the mean time I've bought these

So that I can a 2.4 on the front of the Surly and dispense with the horrible aluminium fork. Rode at Glentress today and it sucked, Glentress sucked (big time) and that harsh ali fork sucked dogs balls too. Got a front pinch flat, I'm blaming the 0.1" that the front tyre is smaller by and also those Conti Verticals have pish thin sidewalls.

This whole thread is fuckin' awesome, I appreciate/respect what you're up to.

Maybe an On One fork is the answer to what you're looking for.
Can't find it online right now but mine came with both canti and disc brake tabs and can fit anything from a fat 26 inch up to a 29er easily.

The On One forks are a bit long.

I'm enjoying riding with the correct length of fork for a change (though the twitchiness does occasionally catch me out!).

i don't know about suspension correction but this looks good.. pricewise not so much, tho

Heavy and stiff.

I've been wanting to fit a front brake to my bmx for a while but my fork lacks the mounts. I've bought a pair of u brake posts (and a rear disc tab that'd maybe fit the 1x1) from Ceeway and I think I'm going to try silver brazing on them to see how it goes.

I figure having a brake come unstuck when I'm doing an endo in the skatepark down the road is gonna be a metric fuck ton less of a problem than it happening when I'm chucking myself down a mountain in the back arse of nowhere.

My Thomson dropper has had to go back to i-ride again because it started wobbling on the 2nd ride after supposedly getting new bushings but regardless, I've fitted the P2, a 2.4 front tyre and a shorter, braided brake line.

Also, my bmx now has a front brake. Not sure how long it'll stay attached but seems sound so far. Not really getting much performance out of it though, I'll need to wear the paint off the rim then change the pads to see any meaningful power from the brake I think.

Nice and neat.

Built this today from spares and stuff I've had kicking about for a while. Only purchases for this build have been the chainring £2 off ebay and a set of brake pads.

"Multitude of bikes" is about right...

The Surly is looking a lot of fun.

"Multitude of bikes" is about right...

Today I fell foul of having so many bikes; rode the trials bike in the morning - I can back and side hop and stuff but can't hop while moving coz it's so much longer than my bmx I think then rode the bmx this evening, kept forgetting it has a massive gap in the freecoaster so constantly almost falling off it.

Been fiddling with the trials bike recently,

Bought some HS33s off german ebay for about half what they'd have cost me in the UK, rear wasn't for fitting round the wide trials rim though so I chopped up the EVO2 mount plates and extended one with part of the other,

Then made a booster to go with it,

Impressed by this brazing-at-home stuff. I'm off to do a welding course next month and hope to make a rack in that course. Would like to continue doing bits and bobs at home afterwards though.

This booster is all sorts of awesome. Always rattled me evreytime I saw how much force the HS33's put on the tubes. Holy flexoid!

I'm interested in how you made the front rack. I've got no brazing or metalwork experience, although ironically I used to translate welding manuals for my job. I'm not bad at electronic soldering if that makes a difference(!)

Anyway, how easy/cheap do you think it is for a beginner to get a passable beater front rack like yours? I'd probably go for a more traditional design, like a flat-top, pizza-box rack with maybe a wire mesh.

Hey sorry I didn't notice this.

Before making the rack all I'd done was put the cross in the back of the flyer and maybe make a pentagram out of spokes so I was far from well practiced.

As for how the rack holds up, I'm not sure. Time will tell.

What I would say though is that just the basic cross shape for my rack was 12 joints and I made a considerably better job of the last joint than the first so maybe if your materials are cheap enough, make one practice one and then the one you'll use?

I'm just looking out some photos of what I've been doing with my torch more recently...
