    (Re)reading this thread makes me feel like I'm fully able to restore one myself! Now to find a basketcase and a large pot of gold.
    This still is such a great read, I love the effort you've made on bike and detailed buildlog so far. Thanks!

    I got these pre-bent pieces of 1-1/4 inch exhaust tubing from Columbia River Mandrel Bending:

    The rear pipe was the easy one. One of the short bends only required a little work to fit as the bottom half:

    Then I tacked a short straight piece and the flange to it:

    And finished welding it out:

    I made the front pipe in the same way, but it had a few more pieces because it has to bend out around the timing cover then back in between the footboard and the engine before lining up with the muffler:

    Here is the breakdown:

    After that I finished out the welds, grit blasted, and painted them black. Good enough.

    Just thought I'd share this link. It'll be on the new motorcycle Cannonball website, coming soon.



    Have a good weekend, friends,

    It's been almost a year since I've worked on Patience. I think I was a little bit burnt out on it. Today I commenced the post-Cannonball tear-down. Here are todays before pictures:

    And here are todays after pictures:

    I know, it doesn't look like I accomplished much, but I had fun doing it. Details to follow.

    Kevin,

    Just curious, are you going to just re-braze the exhaust port and run another clamp?

    Later,
    Devin

    I haven't decided yet Devin. I'm exploring a couple of options. Know anyone with a good 1916 front cylinder for sale?

    Probably the same folks you know. If I find anything down south I will give you a heads up.

    Hay Kevin If you look over at jay leno garage youtube there's a interesting video that may apply to you. Jay had a white streamer car part 3d scanned . They corrected any faults it had in the computer image they made. Then they sent the file over to the company and 3d printed in metal. If I remember the cost was 1000.00 . Take a look might be a solution to old bikes like yours.

    Years ago at Davenport AMCA I met a high level engineer from Buick in Flint- he was carrying around a IOE cylinder from some ancient motorcycle, badly broken up. He was looking hard for a replacement. He said he had talked to the foundrymen and suppliers at GM, and they laughed. "We could never make one of those, it's lost knowledge". That was in about 1990.

    Good ideas, interesting story. Little known fact; those early Indian castings were made by Brown & Sharp, the New Hampshire tool maker. That cylinder actually has B&S cast into it.

    Since that front cylinder exhaust port has already been brazed, I think that's my only option for repairing it. I just need to figure out a way to reinforce it in addition to the brazing. I have some ideas, I'm always interested in your input.

    Thanks for the comments! Please keep them coming.

    Kevin,

    Matt Walksler built his JDHXR and had a set of cylinders modified so he could run dual carbs like a XR model Harley. He said he had Justin Wells of Ohio do the work. Might be worth contacting Justin to see if he could rebuild the exhaust port. I don't have his contact, but can ask Matt for it if you would like.

    It has taken years but Harley JD cylinders are being made again in Australia. It's a good read.
