the head looks like it should seal with a composite gasket, those cams however, are toast.

I saw this at handbuilt 2019, it was understated but all very well put together, it's nice to see work like that

check out "desert hybrids", I got the plans there, there are some things I would change, like increasing the crankshaft diameter (it flexes too much when thumbnail shrinking). but otherwise it's a good set of plans to start from.

video of welding one of the frames

some fun progress, I've finished the remaining bent tube parts for the frame, I had to do some multi angle copes on the engine mount tubes, so I 3d printed some "jigs" to hold the tube down at the right angle and hole saw it on the bridgeport, test fitting with the crankcase proved they work...

started putting the frames together, doing 3 at a time certainly saves time in cutting the metal up, not in welding, but it's still a good idea I think. The frame basically aligns itself, so no actual jigs are required, just have to maintain the tight fit of the swingarm bearing tube and...

thanks, they're 6061

and omg lol I just realized I clamped the fender to the upper part of the fork leg, that would be funny to actually build it not realizing the wheel would hit the obviously not moving fender

here's a bit better rendering, I've continued to detail the assembly and fill in some of the tiny little things like how the headlight mounts, finished designing the tree clamps, etc, there's a lot of time put into pulling part numbers from mcmaster and inserting things like screws, bearings...

nothing too eye catching to show lately, but I finished the frame design 100% including detailing all threaded inserts, tabs, etc etc. so I started machining the actual parts for them, just lots of accumulating pieces, then putting everything together. What I am hopeful about with the designing...

could be that for some crazy reason, the shock needs to be completely disassembled to refill the fluid if the system is exposed to air, you'd think you would be able to reattach the line and reservoir and bleed the air from the system by pumping the shock, but... who knows.

I have some tech that you might be interested in. think of tooling costs as about 1/10 of that. per unit will be higher but still offer a great margin if you price the tanks properly. the cb350 tank on my build thread was done using my tooling tech.

I like what you did with the alloy fenders, have you thought about offering an alloy tank for sale too?

Started and finished swingarms today, machined the parts and bent the arms yesterday, but it didn't really take the whole day, so maybe 10 hours into 3 completed arms. Not bad, the goal here is to streamline the build process by A: building a series of basically the same bike and B: using tech...

I 3d printed some flanges based on draft angle from the 3d model, then started building the mold. I'll be trying prepreg for this seat, usually I do infusion for carbon fiber, but I'd like to try using prepreg more because it doesn't require as complicated of a mold, I can use my powdercoat...

Working on it! I do machining and problem solving in the manufacturing area, some product development too.

if you're rebuilding the engine, there's not too much point in getting it running first

my neighbor has a plasma table, I helped him get it set up and assist with troubleshooting things for him, so I get to use it when I need to, it zipped off the parts for 3 tank bottoms in about 30 minutes, saving me maybe 3 hours of templating and cutting on a band saw. everything fit up and...

I pretty much finished the seat for building a mold, that just involved primer, bondo and sanding, the pattern then gets waxed, coated in PVA, flanged, and a mold will be built on it. I also set up the swingarm jig, it's a simple tool I modeled in solidworks so I can use it over again with a...
