Did my own Pipe Repair

[NathanMember]

After dinging my expansion chamber a few times in the last couple of months i had one, a fmf gnarly repaired by a bloke which cost me $80. (Which is very reasonable).I figured i should learn how to repair it myself.

I love special projects and my missus usually gets much amusement in the research I put into them as well as our special field trips to procure supplies for my special projects. :dry:

Once i worked out how to do it and completing a thorough risk assessment and JSA which included a hot work permit.I set about getting the job done

I blocked the ends off and pressurised the pipe after a thorough clean, degrease and CO2 purge. then hit it with a Mapp gas torch.
after heat.


Then i gave it a bit of a clean and polish.



.

Before i attacked the Gnarly i popped out a ding from my twin wall OEM Pipe which the shops said couldnt be done. that was my first go and i was very cautious and nervous about the process and know i can get the OEM pipe looking good too.

cheers

Well done tf2
Love the vice on that special work bench mate
Great job, you’ll have people lining up with dinged pipes for miles. I’m first :laugh: :laugh: :laugh:
Send some pics of the jigs that block the ends if you don’t mind mate and I’ll knock something up so I can have a go at Smurphs old pipe
Cheers

Good effort mate,easy when you know how eh, Next you should have a go at making a fibreglass or carbon fibre gard.http://www.obtrailriders.com/index.php?option=com_kunena&Itemid=56&func=view&catid=33&id=19009

The satisfaction gained from doing it yourself is always a good thing

Pipe guards are for Fags

Just kidding.
those hyde guards are shovels. i had a u bute $260 carbon guard which took small things like rocks and small branches when i had the OEM pipe and still put a big depression in it on my first ride with Murph.
Then i bought a FMF Gnarly and i cant find a pipe guard to fit it. have dinged the gnarly twice since then nothing major but cost me $80 first time so i will just run the gnarly bare back and fix dings when they arise.

actually next project is to build a cro mo cage like the PRP guards to fit up to the gnarly. more investigations and risk assessments :laugh:

the missus gets plenty of enjoyment out of the way i conduct my “special projects” too Murph.

will do murph i will take some close ups and send em through when i get a chance. you with your knowledge should be able to come up with a better design based off what i have got. if you do i want one. can give some advice on it now after fixing my pipe.

Thanks Ollie
Nice job there mate
Now comes the questions

1)Do the bolts just clamp onto the pipe? Obviously there is a rubber gasket ie the pink material on yours

2)What sort of pressures are we looking at? Can’t be much or it would blow the ends off easy enough?

Yes Murph the bolts clamp to the pipe you can wrap the pipe with some electrical tape so the bolts dont mark the pipe and it is a neoprene wetsuit type rubber gasket.

pressure is about 50 psi max

Excellent job there young TF2, Better than new.

Boony I find that pipeguards i have used in the past run the risk of snapping the pipe junction at the barrel, or transfering the shock to a couple of points on the frame downtubes and seeing as a pipe from the wreckers is $200, or you can do a repair like the above I’d prefer to run without one

Just saw Ollie’s link. I have borrowed a KTM carbon wrap over guard (hardparts I think). It’s strong but not good for hard impacts as you can bend and crack the pipe as you say. My mate Grant here in town has made a carbon/glass composite that mates with the alloy bashplate and the front of the engine frame cradle. There might be images of it in the Murphberg Basin ride report…. That unit took some planning I tell you. I remember sitting in front of his bike for about an hour brainstorming with him. Our solution is quite elegant. It will take a tree stump to either side at single trail speeds – that’s proven. I will be undertaking my similar design over Christmas with some enhancements. We use police fingerprint black powder mixed in with the resin to give it a real dark matt finish. Gloss looks very ordinary.

Oh, and nice work tf2. fantastic results there.

Nice work Nathan, that came out extremely well for your first go. It almost inspired me to run without my pipe guard and fix the dings myself. Almost….

When I get a new pipe I’ll ditch the Hyde guard. I’ll need to get a bashie then though.

:laugh:
