First ride at last

I took my first ride tonight it was great, I did it under the cover of night and traveled only 2 blocks. I still need to adjust the carb a little, there is more power in there I know it! Anyway here are some photos, I don't consider it done yet it will probably be a work in process for a long time.

BTW: the wing nuts are already gone.

large - that is the stock clutch drum on the Ryobi it seemed to have a bearing between it and the engine shaft. The drive roller is from an old torque wrench and I was able to adapt it to the shaft with some square tubing that just fit over the shaft attached to the clutch drum. the bearing on the other end came from True Value and it was a perfect press fit to the roller. Everything went together pretty smoothly.

egor - that is a work of art, I am not sure how that tensioner works but it is cool. Post more pics if you can.

autobo7 - the roller depth is adjustable I didn't check it when I took the photos.

SirJakesus - I am going to clean the lines up and paint it soon, I took the edges off the metal but it is still looks like it will bite me if it gets the chance.

As for using the woman's frame it was available when my wife bought another bike. I have the same bike in a men's frame as well. Although it did cross my mind that it would be better for a quick escape.

Thanks for all of the kind words, this is a great forum.

P.S. I added a set of handle bars off a BMX bike, it makes the ride much nicer (thanks for the idea large).

The simplicity of a friction drive is good. **** motorised bikes...So much fun, so little money
 
Hi, SVH
That is one SWEET LOOKING RIDE!
It is an excellent job!
Really, I think it's outstanding work. It looks solid, mounts easily, has a clutch and is all yours! I love the design!
Massive kudos, man! Nice work!
I'm eager to learn how you attached the spindle to the clutch since that is vexing me right now!
Your build is a real inspiration to me and, I'm sure, others who are tinkerers at heart!

Thanks again for sharing!

The photo is blurry I know, I was in a hurry hopefully it will help. This is my Ryobi 4 cycle, it has the same clutch bell as the 2 cycle I have on my bike now. The square tube stock is to the right of the clutch bell, it comes in 3' lengths and was only about $4 at Menard's ($8 at True Value). Once the round end of the square shaft on the clutch bell is filed away enough the square tube stock will slide up to the cylindrical portion of the clutch bell shaft. My drive roller then slide over the square stock and the round part of the clutch bell shaft. I the pined the drive roller to the square tube stock with a #10 machine screw. I use the bearing on the other end of the drive roller to hold the assembly in place against the clutch bell. This works great with my roller but it could be modified and used other ways, the square stock provide a positive attachment to the clutch bell shaft which can still be removed easily and the shaft remains almost unchanged except for a little filing.

Clear as mud!

Sweet Valley - On the tensioner he used, it looks like a long bolt and placed on the diagonal to a fixed location lower than the end you can turn it pulls the motor down to the wheel. This is another pic, a very purty one and another view, and the last just for fun, and crop dusting. Have fun, Dave

Hi, Egor
That is one PURTY build. It reminds me of SweetValleyHigh's design.
The tensioner is VERY clever.
The crop duster is a blast!

Thanks for sharing those!
