To answer some more questions: yes I used a MIG gun welder(miller-millermatic? I think). I want to use a TIG welder on my next project, but I was scared that they are fairly difficult to use. whereas the MIG gun is point and shoot.

The bike takes square edged hits really nicely as the pivot is very high up, it makes for a slightly rear-ward axle path.

No- I can't move the pulley up anymore as the pivot is right in the way, and the chainline wouldn't work if the pulley was inside or outside of the pivot.

The shock is a 2.75" stroke shock at 3:1 giving the bike approximately 8.25" of travel.

And lastly Buell is not allowed to ride any of my bikes.

You deserve one of those beer commercial jingles...

"Heres to you mr. mountain bike frame maker man......"

 

[dcamp29]

Oh yeah- I ended up spending about $130 on everything. (bearings, tubing, bolts, etc.)

 

[OGDMFG]

it my be you have to work the pivot and the pulley for a compromise

just my thoughts,been bulding for a few years.here is the latest one using a back and up pulley system. OUTSIDE12.jpg (5.0 KB)
nice work keep it up

nice work

Awww Dang!

Anyways, good work, making your own bike is something to be proud of.

You're lucky Sully lets you dink around on his bikes! Ha! neaky:

Dave, how did you come up with your design? With the pivot on the seat tube. Is that mainly for the wheel path, or is there other reasons? Its definitly different which I like. Do you think it would peadle better if you moved the shock mount to the top tube making things more linear? Kind of like the commencal.

 

[dcamp29]

the design was purely for wheel path. and that part was a success, but i don't think moving the shock would help with pedaling. that would adjust shock rate(to a more falling rate-so it would start feeling stiff, then bottom out real hard.), and the pivot location is what is really hurting my pedaling right now.

Is the down tube up to that much force?Probably giving you another half inch of travell. I guess it would soften the bottom out. You could have had the top of the swing arm come further forward and run the shock more vertically like a Balfa.
Excellent job though,I'm just speaking my mind but you've done it,if I had a hat on I'd take it off to you.

wow, i missed this thread david!

cool to see it done.

the bobing has to do with the height of the pivot. with the roller
below you are exstending you sus with every pedal stroke then the
leverage of height of you pivot it sags then back and forth causing
some bob you can feal. i would keep it concentric and newtral
rather than working against eachother actually causing more bob.

great bike. i love the frame jig!

For any one that doesn't know, dave actually raced this bike at the Snowmass blast the mass after getting his faith stolen, placed 11th in pro.

snowmass MSC race

fun weekend

 

[kohoy]

Great job man~ I like the design of the frame... wish to make one myself also but no clue how to start....hehe anyway... nice crash shot.... hehe

 

[Bldr_DH]

Mmm... not a crash shot, but I suppose it sort of looks like one. Mr. Camp there is a pure-bred pinner.

 

[BIRDMAN111]

Very, very nice! Regardless of how it performs or how long it lasts you have done something every single person on this board has drempt of doing..... making THEIR OWN dh frame!

dude, dont you remember that vt guy that made his own carbon dh frame?

 

[mattmatt86]

when will you start taking orders? Id be interested in one, or possibly a smaller 4x/DJ fully

 

[ZoRo]

Love the pics... and that huge patch of ice! Nice build too

 

[k9handler]

very cool...must feel good! I work on my own car and when I push it on the track I always have in the back of my mind..."did I do that right"? Congrats on a job well done.

 

[mtb527]

very nice!! but the head tube looks weak especially with the welds of someone new to welding... what kind of welder are you using??
