Juicer 48, the Etek build

[Flügelwagen]

It's been slow-going for awhile...still pimping Juicer 36 (see the media page of emotorbicycle.com) but have finally started to see some visible progress on my second bike, the Etek/Worksman build.

These are the proportions I'm going for, but will have to make custom forks and add a loop to the frame to cradle the Etek.

The forks will be based on the Brain Fork ingredients, but this is not a chopper, so changes will be made.
You gotta love John Brain. Most folks who come up with a great design keep it to themselves, or try'n sell it. Most would worry that if they publish their plans in an act of generosity that somebody will botch it, crash and end up suing your pants off. This did not deter John Brain. I tip my hat to you, JB.

Drilling one inch holes in 1/4" steel with a hand-drill was not my first choice but was forced to after one plate failed the stringent Juicer QC. After going through two other bit brands (white and black) this red sucker got the job done. I cut the flunked part in half and used the pieces to squeeze this nice pattern into the fork-legs. Unfortunately, to get them flat I destroyed my new, blue vice that I got at Sears. It did not say the magic word, "Craftsman" on the package, so I was out some bucks. Determined not to bring another knife to the gunfight I bought this giant antique vice for $80. End of problem.

Hydroencephalac forks; Brain Juice. I inverted the positions of the plates to eliminate the stretch. For risers I'm using identical stems. I bent the bars with a conduit bender...kind of a wide, hoopy bend, but does look old-timey.

I had to get the frame loop bent at a machine-shop. I h8 having to pay someone else to screw up my parts when I can screw them up for free.

Here's the hubbub at the hub hub; going clockwise from left, for the rear wheel I was going to use this nice kart-bike part before I found the heavier-duty scooter part that came with a 45t sprocket mounted already. I threw them both over for this little BMX hub with Left-Hand-Drive. Why LHD? Because I'm banking on a hunch that a coaster-brake hub will make a great jack-shaft...

Coaster-brakes are actually an overrunning clutch and a drum-brake all in one. As much as I would have liked the look of a freewheel crank setup, I didn't have confidence that the pawls would stand the stress of a 14hp motor. Will a free-coaster explode under the strain? That is TBD. But if it holds, I believe the braking feature can be modified to be cable-actuated which will make it an ideal regenerating brake.

Where did you find such a great old vise so cheaply? I can't covet or lust after it, but that's one great vise; I'd love to get it's twin.

I would still like to buy a copy of that mid motor drive you created for the original ejuicer, but don't want to pay $800 for $20 worth of metal.

I feel lucky to have found it, Catfisher. I got it at an antique salvage place in town. I'm sure you could find a similar deal in Illinois. Call some antique shops that carry tools and ask if they have a big, old vice. Worked for me.

...finished the jack-shaft carrier today. I'd value the metal at about $2.75.

Jackshaft carrier mounted; even though I stripped the frame to metal near the welds, the Worksman frame fumed like galvanized metal. It smelled like a future in the respiratory ward.

...the motor-mounts have joints like this. There are templates and programs to plan such intersections, but they didn't work for me. Instead, I got one real tight via trial and error, and rolled it in paint to make a template for the rest.

Ah, the frame is done at last. The loop is sleeved in the seat tube and gusseted at the down tube.

If you're a human, like me (allegedly) toolmaking is a satisfying activity. The task was to hollow out the bars for my bar-end brake levers. The tool is another "practice" part from the fork build slit down the hollow end to hold folded sandpaper. The threads that were welded to the other end fit into my drill chuck. This did the trick...eventually.

So I dusted the frame with primer and slapped together what I had so far. The fit to the Etek is tight and balanced. The aluminum face-place will allow me to mount the battery trays a-la Juicer I.

Speechless.

I am sure that is the reason you have not gotten responses.

Everyone is speechless.............
