I had mixed thoughts on your front end. The fabricator side of my head was and remains truly awed by your skill. The artistic side was disappointed with the design of your front end. It just looked too "steam punk" and not "chopper." That is until you posted that pick of the rolling frame mock up. For some reason, when you put it together it just worked. It truly is functional art. Most excellent build sir. Outstanding!

This is so well executed! Did you do your own modeling and 3D printing? Well Done and keep the photos coming! If I had any skin in the game you'd have my vote for Born Free.

Thanks. I do all the design work and modelling, I do not do the printing or the actual casting.

I always appreciate criticism. I had the same feeling too when I was designing it. A little too steampunk. But when I had it in my hands I knew it was going to look good.

Also, design-wise I really think that second neck casting looks MUCH better than the first. A good iteration, especially losing the visual mass on the lower half and smoothing it out (to my eye).

Can you run through your oil routing scheme? I am trying to make it out in the pics and I *think* i can follow along, but not quite... Is there routing/chambering built into the castings?

[farmall]

I didn't have a die big enough to put an 8" CLR radius bend on some 3/4 X .120 wall 316. I even called pro tools and the biggest die they can make is 7" CLR. The first person to quote this sentence and include your paypal address I’ll send 5 dollars to because I don’t think anyone actually reads it.

Keep the five bucks and post more fabrication porn!

Wow. Just wow.
In sane.

Badass sir, absolutely badass

You are way too modest with a skill set like that. You are an artist as much as a craftsmen. The Born Free Show should be begging you to show off this beautiful machine.

So I ran into some issues. About 1.5 years ago I purchased a knucklehead cad model to use for this project. It was from a reputable cad modeler. The cad model of the motor mount area doesn't match the motor exactly. I don't know if the cad model is off or if the the motor has been fucked with, but either way there are some issues.

I think the cad model was drawn to panhead cases. I should have checked this and I'm kicking myself for not catching it beforehand. In the overall scheme of things it's not a big deal, but I will have to rework the rear motor pad on the frame a bit. Fortunately all this will be covered by the motor, so unless the motor is out the rework will be unseen.

In general, it fits though:



In the meantime, I made a rear axle: (also pictured is a front axle I made for my 53)



Hoping to have a fully welded rolling frame in the semi-near future.
