ORBO Le Klunker de Acatène

+1.......that's exactly what I was thinking when I first saw it: higher looks more racy, lower looks more classic.

Its a win-win situation!

I think it depends on how old you want the bike to look when it is finished. If you want it to look like it’s from the fat bike era, then lower is probably better.

If you want to make the bike look more racy, higher is better. That also makes it look more modern.

Much appreciated! I think I will keep it high. I'm not shooting for the 'old' look, more like a 'nod' towards the vintage klunkers.
Since with the shaft drive there probably won't fit huge tires in there, a sleek frame fits that very well.
Normally I love to see bikes with small diameter tubing and balloon/big tires.

There is a little bit of space now to think about parts. This is just some rambling:

The gear ratio is 2:1. So like a 44t - 22t (chainring - rear sprocket).
That is not bad for a 26" single speed.
My current Klunker has a 39t - 19t ratio, very similar. With 26x2.4" tires.

I have several coasterbrake hubs. Also an Sturmey Archer S2C, but that is not great when offroading (already tried it long ago).
Also have "Araya TM18" rims lying in my shack that I can give a good clean.

• Shimano CB-E110, solid choice.
• Histop hub, already laced with grey rims.
• Old Sturmey Archer hub that I need to refurbish. I wonder what the year is and how the inside functions.
• Sturmey Archer S1C in black, very smooth hub!

It also depends on the frame: Clearcoated or a colour.

Histop hub and grey rims.


Hmm, maybe I should clean the frame and the brazings first.

First parts arrived:

I know nothing about Shimano Dura Ace with JIS square tapered. If someone could tell me more, I'm interested!
But: These cranks are very light!
I bought them second hand for 1/8 of a price other sets go for.
There is a subtle hint on the second photo, but one spider arm is bent. Perfect for.....

"LE SHAFT DRIVE"

I plan to remove the spiders arms completely, but can't make twins of both left/right. So I'll leave a little round shape at the base of the spider arms.

Me next to a roadie in the near future: "My Dura Ace is lighter than yours"

In the meantime I'm also finishing the cigar box guitar for my dad. I'm posting it here because it eats time from my buildoff bike.

Now drying with a 'dark oak' coating on it.

I just found out that this crankset is 1st Generation Dura Ace from 1973.
And non-damaged sets are pretty expensive... and I'm going to alter it in the lathe if that isn't Ratrodding...

Oh, yeah, that's good stuff.

I’d knock them off short with a hacksaw first just to save machine time.

Plus it would make a good picture of you cutting it up.

Hi guys.

When I turned around the jig to work on a few braze-ons like the threaded bush I made earlier...
I saw that the left chainstay is positioned a little higher than the right. Not much, but visible.

Seat stays and loops align pretty good.

So I'm thinking about the options:
A: Remove the loop and check again with a tool of sorts.

B: Remove only the chainstay connection and do that part again.

C: Leave it, since the shaft made the frame already 'asymmetrical'. Maybe I can add something to balance it out.

Little bit/hardly visible.

Just a thought; to add something, since there will be a dropout of sorts.

Maybe I have time to measure it tomorrow.
A little setback in time, but it has to feel right.

I'm working on some sort of tool to hold seat- and chainstay tubes. Also for future builds with simpler seat-chainstays. That way I can properly align them and check them. No need for tacking, just start with brazing. I can finish this tool next week. Maybe I should take it easy and do it right.

To do list:

-Brazing, aligning and more brazing.
-Cleaning the connections and the frame.
-Mockup and parts pile.
-Adapting the Dura Ace cranks.
-Disassembling, cleaning and refurbishing the shaft assembly.
-Final? Assembly.
-There is always more.

I will certainly do that!

Iron worker for the win!

ImPRESSive tools you have access to!

ImPRESSive tools you have access to!

I see what you did there!
I'm grateful my employer lets me work with the machines during break time.

TURNed out pretty good. I'm happy as it is right now.

A little time setback, but I'm working on the tools to get the loop right. Offcourse these are also handy for future builds!


I also found and ordered rims!

Are you guys farmiliar with 'Loaded Precision, AmXc' rims? This is going to be awesome!

 

[BartRidesEternal]

Wheels (laced front wheel and a rear hoop) came in! Found two of these awesome rims at their shop.

 

[OddJob]

This is on a whole 'nuther level! You might need your own category.

Thank you! What should we name that category? Ride Eternal? Or build eternal

Now that I checked alignment of the left looptail, I see that I need to bend and notch that one again. No problem, just learning more. I can pick a CroMoly tube up this week at a shop from someone I know.

Set for the next loop!

I was also checking for forks and fork lenghts in relation to the geometry.

Here are two options aside from the Manitou crown:

That springer looks great but: Its too heavy and too long. If I use this my "Bottom Bracket Drop" is only 10 millimeter.

I do like the red fork with those blue rims!
That fork is about 5 to 6 centimetres shorter. Much better.

If there is time to build a fork with the crown, I might consider that.

I love how this turned out!

I'll leave the plastic foil for now.

The whole family was sick last week, so the bike's progress stood still.

I managed to bend and cut the left loop with help of my extra alignment pillar. That things helps a lot to get things right.

Notching by hand & file remains. Then cleaning and preparing for brazing.

The old loop will be utilized for a few bridges (or what is the name?).

Bend ze loopz

Checking the angle of the right loop.

Bend is alright, now its time for cutting.

Thats how she stands now. With a little luck I can braze this weekend!

Then fabricate the final frame parts and finishings.

Glad you are healthy again.
