I do not like scraping idea's, but some times it is done because I looked into an idea that was bad.

IF the engine was able to be offset with in the frame work.

If the engine was mounted lower than it is now, than the chain line would run under the seat line more, and all may adjust and work out easier. I really like the idea of a chain guard style seat base, but that is me, as I always wonder what would happen if a through a chain while rideing. Just step back and look at solution's that can solve the issue, that is if you still want the seat level low, if you can be higher like that than all should work out, but you have to piece it all together in your mind and than to paper. Need to feel like I am helping some one.

Air cleaner, chain and seat height...

 

[grandpanystrom61]

It could be my eyes, but I see the front engine sprocket height, the true chain level would increase higher as it leads to the rear sprocket. The rear sprocket is much larger than the front.I would just use some simple hose or soft tubing split open so it would wrap around the sprockets and you can see the true chain line.I just do not want you to be bummed out when it does not fit right, or just run a piece of rope around the sprockets, just so you can see that for sure your seat clears the chain. I mean we need enough clearance under the seat so when the rear tire goes up and down the chain height is not rubbing on the seat or anything else..

Thanks again GPS, BUT The chain height is about 1" from the seat and will go to a jack shaft with the 2 sprockets being about 4" in diameter to the rear frame and the seat will be one of the last items being welded

Ordered the jack shaft sprockets today Honda 15T with a 520 chain and Harley 20T with a 530 chain, that's the closest in sizes I could get...

I'll be making something like these, in this area. Any other idea's???

 

[grandpanystrom61]

?, are chains still adjustable today. Years ago we would just remove links and put the master link back in and have a chain to fit our needs. Do they still make them adjustable that way ?

I missed the jack shaft sprocket idea, I see that it is a good idea and would be the way I would have done it also if I had thought of it. Yes a bit out of my nomral area, but I love what you are doing and I am learning so much about it all.

A huge project TomyJ, but I love ever minute of it.

I am having second thoughts about the middle frame rails, to wide for my legs and foot pegs, so maybe I'll double up the lower rails and weld them together, 2- 1.25 sq. with 1/8 wall= 1.25X2.5, should be strong enough??? What do you guys think???

for what u are doing i think that will be plenty strong

Harley sprocket has arrived today so more playing while I wait for the Honda sprocket.

 

[TomyJ]

This is going to take a while, I am thinking of welding the sprockets to the inside of the sprockets and 2 pillow block bearings on the outside, BUTT I would love to put a 2.5" OD with bearings on the inside, I do not want to get much machining done $$$.Things like this really piss me off, here I am a machinist with no machines. Any other ideas out there???

 

[TomyJ]

Jack Shaft

More set up and measurements, Coil spring would be in the way for a pillow block bearing on the ends, Do not like keyways $$$

 

[TomyJ]

Jack Shaft

Thinking of going with the pillow block bearings, one on the inside next to the Honda sprocket and the other outside the Harley sprocket, weld the Honda sprocket to the shaft, slide the pillow block on and then slide the Harley sprocket with key way then the pillow block with 3/8 bolt and lock tight. "How does that sound" ???

 

[grandpanystrom61]

It does sound good to me, but I never built something like this, nor much welding, so what I think on this issue is not worth much. I can say I like how it all sounds, and yes I probably would do the same thing myself, and even ask if it sounded workable. I hope others chime in with their knowledge about it.

 

[TomyJ]

Jack Shaft

More measuring and looking at the machining, will go with a 7/8 shaft, pillow block on the outside will be ugly, can't hide it...:gah:

Now for some machining...

looks like a heim on the right? planning on using that? its not made to support a spinning shaft

I am trying so hard NOT to put a pillow block bearing on the outside because of looks, maybe more looking?

how about a nice cover over it? or

perhaps this type?

Ordered another pillow block...

Ready for some welding and machining soon...

Memorial Day

Honoring my brothers on this day...Scooter did not what to idle other than high, so no little ride for today, play with it later...Be safe out there...

Jack Shaft

Getting closer, not looking forward to the cost of machining, $$$

Different looks for the air cleaner...

Jack Shaft

Waiting on the machining, They said boring 2 sprockets $50. and 4- 1 1/2 solid steel @ 2.5" L. each, drill and tap 3/8-16 centered upright one end each $40. for material and machining, and they will throw in the 2 - 7/8 ID bushings, length TBD. I feel the overall bill is cheap, What do you guys think???

 

[grandpanystrom61]

Some will say no it is not cheap, others will say it is a deal. I say this as cost is a little different in each state, at least what I have discovered.

In general, I say it is a good price as it is compariable to my area, but if you drop down to Vegas it would be almost double the price. Machinist work is getting more expensive in todays world, heck it was always a bit pricey actually.

I like the red paint, hope all works out as you need/want it to...

 

[stacebg]

that is a steal the machinist must be pretty hungry (not much work) maybe i should start shipping stuff out there

Sprockets are bored and mock up for the bushings measured now the keyway in the Harley sprocket, but first a bunch of tack welding...EDIT: Machinist said Honda sprocket was too hard so he turned the shaft down to fit and then Tig welded it.

 

[TomyJ]

Chain Guard

Mock up on the chain guard from the Rebel, little modification allowing for swing arm movement, and it should work...:clapping:

if its too hard to machine there is a possibility its to hard to weld.. ie it may become brittle an break
