..continued

11. Stanchion tacking underway


12. Chandan all smiles, posing with the frame. A lot of the credit for the frame coming to life goes to him. He also kept the team entertained and made sure their were surprises popping up at every step (more on that later).


13. Compressed air used to cool the frame after welding, to minimize distortions


14. The first surprise, the internal faces of the stanchion were offset by 10mm when we checked today morning. Used a screwrod to open it up and align back... a very tricky thing to handle, fortunately the welder Shiva's experience came handy


15. The final masterpiece, at last


16. Chandan posing with the frame again, no surprises this time


17. Top view


18. One last shot.


Things left to do on the frame
1. Engine front motor mount
2. Engine rear motor mount
3. Centre post
4. Foward control holders
5. Transmission mounts
6. Rear shock mounts
7. Neck gussets
8. Backbone support

Great progress luky_13! Eagerly waiting to see this on the road!

Could you tell me why the frame top tube was done in sections (round and then square pipes) and not as a single piece of pipe from the steering head till Y section?

The square pipe is to accomodate the fuel tank, the under belly is square in shape. Pre 2002 harley fatboy models could accomodate round tubes, this change was made to add strength to the backbone of the frame.

luky , congrats for going till now .I remember way way back about you getting the engine from elsewhere and it got stuck in customs and all ..I am right ?

1.One basic question , why not use aluminum ? .
2.How much is the difference in price b/w steel and AL?
3.With a similar frame built with AL how much is weight savings ? . how much does steel frame weigh ?
4.With decreased weight , power to weight ratio would have been better, hence more power , more mileage and better handling ?

Thanks, well you are right about the engine. I was on xbhp some time back, when i posted that info.

1. This is my first frame, not experimenting.
2. Al tubing is very expensive, if i'm correct the difference is 1:5
3. Yet to weigh it, will weigh it after welding left out components
4. Correct, i will take you advise on the next frame i build. A hardcore chopper ! That is if i survive this one.

Great stuff you got going there luky_13, dont have much tech knowledge on bikes so I will just watch this thread with amazement!!

[luky_13]

Checked the tank fitting on the frame, perfect fit... more later

Hi Lucky_13, great project ! Considering something similar, but with four wheels ! Haven't even started mocking things up in Pro-E yet, your project will serve as an inspiration

Can I ask what welding equipment you're using ? I'm considering Miller's Diversion-165 & Spectrum-375, but both are quite pricey, so in a fix of sorts. Any pointers on TIG welders & plasma cutters for the hobbyist ?

Black12rr, along with Aluminum being pricier by a far margin, it's also quite tricky to weld.

Great ! I'm using a RIS, TIG welder. Go for miller if you can... its on my wishlist of drool equipment too.

Man! This thread so reminds me of the OCC shows on Discovery channel! The only difference being a bike is 'made' in the span of the episode (1hr, usually).
Great going! I'm keeping my fingers crossed for this project to be a success! ( and it sure looks like it will be!).

this way better than OCC.. they have the latest hardware n softwares man.. this is a DREAM build.. one of its kind to even think of something like building a harley from scratch in India itself! truely amazing..

Hey its really one more awesome project from scratch,only few individuals take the design drawings from board to garage and then to streets.
i really feel proud that knowing he is indeed FATBOY you started feeding him .. ... please document all the stages of your work, which will be very helpful for your future design and analysis....and who knows Discovery people may knock your garage door at any time..

Fantastic thread, I'm eagerly awaiting more updates. Great job!
