Anyone care to check out my homebuilt frame?(26 posts)

Anyone care to check out my homebuilt frame?Nessism

This is frame number six. It's actually a frame for a friend. Tubeset is Dedacciai ZeroUno w/Reynolds 725 chainstays. Built around a straight blade steel fork - also homebuilt. Measures 53.5 cm C-C and weight 3.8 lbs. It's painted with PPG Deltron basecoat/clearcoat urethane paint. Total material cost is about $200 - and about $1K in tools.

Oh, and Kenai is an area in Alaska where my father is from. Also think, Keen-eye as in attention to detail.

Thanks for looking.

Wow. Very impressive.
How much of your design work is "science" (where you know that if you do something, you'll get a specific performance outcome) and how much of it is art and magic?
And which do you enjoy more, the design work or the craftsmanship?

My design work is limited because I only build with lugs. The tube sizes are predetermined with the exception of the rear triangle. I've played around with several different brands of tubing but haven't gone the superlight route because I don't want to build a flexy frame.

So to answer your question, within my limited range of scope, I have a pretty fair idea of how a frame will ride before I build it. The design work comes in relative to deciding on the angles, geometery and rear end tubing.

There is also a certain amount of irritative design work often termed "experience". Theory regarding how something will work must be proven in hard metal. To that ends, I've now built three frames with the major difference being the style of rear chainstays. It will be interesting to see which frame feels stiffer through the bottom bracket.

As far as how to learn, there are books and a nice internet email forum that is very helpful. I've made my share of mistakes both on the building and painting side. But at this point, at least I know when I've screwed up - knock on wood!

Where did you get all of the tools to build it? Where did you learn how? Did you do the painting also?

cool name and paint scheme.

what's the geometry(angles and measures)? why the steel fork? what does kenai means? what's the meaning of life?

Just a guess...Nessism
Mar 28, 2002 11:35 AM
...about 60 hours? Including a full size drawing and painting. Too many unless you live live in a cold climate and can't ride in your spare time ;-)

Making your own frame. Like having your cake and eating it too.
Bravissimo, does it have an english or italian b.b.?slow-ron

Another tinkerer on the board that inspires me.

I like the socket drops & seat lug. The scheme kind of looks like a Redline cyclocross bike that a friend of mine has.

Keep up the good work.

Nice looking frame. What could be cooler than answering the question where you got your bike with "I built it". How much time did it take to build it?

i'm looking for a new frame, how much for a 55 cm? i'd be willing to guinea pig one of these for sure.
Liability concernsNessism
Mar 28, 2002 6:32 PM
In order to sell frames and protect the family, liability insurance is a must. Unfortunately, my understanding is that said insurance costs upwards of $2200/year.

It's not that I'm worried about the frame comming apart but rather someone sueing me for something stupid. Second or third owners even.

Plus, there are way too many professionals that can build much much faster than I.

Very attractive. My envy is large.
1)Front triangle tubing O.D. & wall thickness?
2)Milled your own rear drops?...Mat'l.?
3)Home made alignment inspection jig?

The front triangle tubing is standard oversize sizes: 1-1/8" seat and top tubes, and 1-1/4" down tube. Dedacciai ZeroUno is made with a high strength alloy similar to Columbus Nivacrom. The tubes are butted .8/.5/.8 mm for the top and down tube and the butts fairly short. The rear dropouts are made by Long Shen and have external sockets that the stays plug into. All the fittings and tubing were purchased from Joe Bringheli who lives local to me.

I made the alignment table by having a large slab of steel blanchard ground flat and then attaching a fixture which clamps the bottom bracket. The plate is very sturdy which allows me to both check and cold set the alighment as needed at the same time.

... and 73 degree head- and seat-tube angles is going to run me how much? Do you barter?

Next thing you know, we'll see Kenais showing up in Gary Hobbs' inventory.

FWIW,

Master Ness,

Another very cool frame--it's not Kevin's size, so whose is it? I like the classic-look decals, also, really goes with the lugs. What components are gonna be on it?

I was thinking that I need a few more bikes so maybe I could commission you for a CX and fixie at some point, that is, if you're interested ;-D

I am trully, trully impressed! Even from the picture the craftmanship is clearly exceptional! A bike for northern Europe I'd say! :)
