Klunker build. (Testride! pg2)

[BartRidesEternal]

Finished the stem and very happy with the clamp-brazing!
I disassembled the bike and removed the fork because factory stock, bikes have a few licks of grease compared what I like to use.

Brand new in sale..... could not find a second hand one or utilize the milling machine so a brand new one.

Oh yeah!

Leftover scrap.

This I need!

Still rough, I will clean that up later.

Marking the radius for notching.

35mm drill.

Checking stem length or reach. I don't like very long stems.

Test.

Oh yeah, I'm getting the hang of soldering / brazing!

Cleaned, sanded, rounded and painted!

That a little dry for my likings.

Wheres the sticky stinky stuff gone?
I'm going to put a lot of grease on there!

First testfit after fork re-assembly.

You can still recognize the fork crown right?

Stem looks great! I taped the frame because I'm removing some brackets.

Next job: Engineer + fabricate something that makes this pin more stuck in the hole. Now I can feel the tick-tock "play" when accelerating and braking with the coasterbrake.

Like I mentioned earlier, when I pedal or brake hard, I don't like the 'play' in the crankpin and the disc/sprockets hole.
I already changed the pedal threads from 1/2" to 9/16" a while ago.

I came up with an steel bush that I filed to fit the crankpin. It has a collar, so when the disc/sprocket is attached, it can never fall off.

Result!

Now it has a larger surface area to 'press' in the aluminum disc. Much better.


And the hubs are lubricated! No cleaning necessary, since this bike has seen only 2 kilometres or so. I only had to remove one long hair on the brake side bearing. Nasty!

Histop coasterbrake hub. Not my favorite but it does the job, especially here in our flat country.

For final assembly, I'm gonna change the washers for a larger size.


Next is thinking about paint. I'll leave the orange on, but I want to add or change the black front of the frame and headtube.
Suggestions are welcome!

Thanks for reading!

That stem came out great, very creative!

Thanks! I'm very happy too. People are asking me if I did some tensile testing... I said I'm trying it out on the track! There a race coming up in a few weeks. Maybe I'll take an extra stem just in case...

Hi guys, what do you think of the cockpit so far? I'm pretty happy with the looks.
Position and if I'll use the setback seatpost is something I will have to check before riding trails and trips.

Pretty tough! The bush can't fall out because it has a collar between the 'Asco power disc' and the crank pin.

Looks great! That stem came out real good. It will be interesting to see how it rides!

Looks awesome and powerful. You are helping me with decisions about my set of moto bars. I'm inspired

Thank you, I agree. Depending on the ride, I will donate this or my other Klunker to the mountainbike museum the 15th of December.

Thank you too Matti, always happy to do tryouts and inspire.

I assembled a few more things and adjusted the stem.
The sprockets will be: 39 teeth up front and 19 teeth on the rear. 670mm diameter wheels.

My old Klunker has the same sprockets and has 650mm diameter wheels.

Large washers and a thick 19 teeth sprocket.

Brooks C17 carved seat assembled! Almost there!

Left to do:
Details like paint (headtube). Maybe a few stickers. I'm thinking about keep it clean.

Chain.
Some neat orange and/or vintage grips.
Adjusting and cleaning.

Testride, today, not an actual trail, but on tarmac. Very happy with the result so far! Stem survived my full weight and wheelies.
