Jackshaft Dual side freewheel crank?? No jackshaft needed!

[5-7HEAVEN]

Umm, Jerry, I’m creating something where the pedals won’t spin.
My idea is beyond shift kits and jackshafts.

You’re right.
Jack shafts are simple devices, used even on factory assembly lines, and inside manual transmissions.

Since pedal and engine power both are going through a single bottom bracket spindle the pedals are always going to spin under engine power. The only way I can see this possibly working is you have to have two drive spindles. The engineering feat here would be to combine the 2 drive spindles into one drive spindle. This can be done by having a spindle inside of a spindle.

The outer spindle uses engine power to drive only the chainring(s). The inner spindle uses pedal power to only drive the chainring(s).

The Sick Bike Parts only uses a single freewheel and a single chainring. Unlike the SI shift which uses a double freewheel system and can drive up to 3 chainrings.

A double freewheel system like what's used in a Staton Inc shiftkit would make this possible. White Industries right side freewheels would be all that's needed and no special crank arms would be needed. But it would require a special bottom bracket and inside/outside spindle be built. Essentially you'd be moving the engine drive sprocket from the far right side of the shiftkit over to left side of the bottom bracket. You may even have to cut out your bottom bracket tubing and put in a larger tubing for the bottom bracket.

To keep from having to mount such a large left side sprocket you could attach a 4G transmission (though you may need a special adaptor with a RS 35 engine) then run from the output of the transmission to a smaller left side bottom bracket sprocket.

David Staton could build this for you.

I'm way ahead of you.

Read my 3-month-long post about sending engine power thru the bottom bracket.

I'm DESIGNING this, as well as BUILDING my creation.

I have not come across ANYBODY on the internet that have done this.

And no, Staon won't build this for you.

He would've built it already.

Lol, you really LOVE! this guy.

I buy his stuff, don't get me wrong.

I just don't lick his boots.

Am I good friends with David Staton; the answers is yes. Do I own a high tech machine shop like he does; the answer is no.

On several occasions I've designed things and had David build them for me in his machine shop. Or found ways to improve on an existing product.

Broken Rear Axle

A few months ago the rear axle broke in my Staton Inc hub. It broke where the snap ring groove is. So I had David redesign me a new axle. The new axle no longer has snap ring grooves. Instead it now uses sleeves to hold the sealed bearings in place.

The reason he hasn't built such a thing that has been presented here on this topic is because no one has sent him drawings on this. However if you did, all I'm saying is he can make about anything you want in his machine shop with a good set of drawings. Now if you have your own machine shop or want to use some other machine shop that's your personal choice.

I'm all about innovation, I've got the auto shifter working perfectly now. Went for a ride and the old Wal-Bro carburetor went out. The generic replacement being sold on eBay fairly cheap actually has adjustment screws on it and works better than the orginal. The bike sat up for awhile and the RS 35 valves need adjusting so I'm currently waiting on a top dead center tool and the actual feeler gauges I need to adjust the valves. Then I'll be doing a tread on the autoshift derailleur and another on adjusting the RS 35 valves.

I'm going to assume this is the tread you're referring to:

Anyone Running Power THRU the Bottom Bracket?

Sounds like you are almost on the same train of thought as me, just a boxcar away. That should work too, I just hate bronze bushings. If you make external cups for the outer shaft you can use a much larger outer shaft. Then you can use sealed bearings through it for the inner shaft to ride on...

I'm not sure if I've ever responded to it. I'll just have to look. I'll be sure to read through it. However, the shaft inside of a tube going through the bottom bracket concept just came to me today. Very often someone may suggest something. It may not be what I was wanting to do but a slightly different version of that idea may be exactly what I was trying to figure out.

 

[5-7HEAVEN]

I’m doing it.

If Staton would agree to build it for me, he’d probably charge me over $1,000.

I would design it. He’d build it for me, then patent it himself and make untold thousands of dollars.

I’m gonna design it, build it and donate it to the masses.....

so some regular guy in West Virginia, India and South America can build and enjoy it.

I totally understand your prospective. However, as I stated earlier many here myself included don't have the equipment to do advanced machining. Which for those who need parts made David can build them for you, this is all I was simply saying.

Thank you for explaining.
