I do like your approach to problem solving. That hose attached to the caliper with a shraeder valve was brilliant simplicity. With that gear reduction, the bike will climb up a wall at idle.😊.

You know, if humanity had Donn DIY in charge of mechanical engineering schools, we could have interstellar colonies in about 10 years. Instead we have electric cars being followed around with petrol vehicles with generators.

[@mlsargent51]

I was just dropping down here to comment the same thing, about the caliper! I'd never have thought of that!

[@tedbastwock3810]

A true artist. We are very lucky to have this content, thanks Donn! Re: that sprocket ratio .. are you planning to tow log trailers with this thing or what? 🤣 Looking amazing, friend, thank you so very much for continuing to share your genius with us.

[@DonnDIY]

The rear sprocket seems big but according to calculations it could be too small since the tires are 22" in diameter. But we'll see, hoping to testride this minibike soon.👍

Donn I love the way you think your way through a problem, your mindset to overcome, love ya brother

[@paul4124]

That was definitely an “oops” moment. I’ve played “helicopters” on a drill press quite a few times, but not so far on a lathe. Keep up the good work Donn. All the best from Aus.

[@karnesmotorsports]

I have an old Sheldon lathe. Didn’t think I would use it a lot when I got it. But man do I use it all the time! Such a handy tool to have!

[@thunderstruck1078]

It's time to make a 20-episode series about the lathe cleanup :)

It is so much fun watching you build! This thing is super beefy and stout! It reminds me of how over-build old Honda 3wheelers were made! I can't wait to see more! Hope all is well Donn!

The engine slides back&forth 👍

buen trabajo amigo ,aunque la TORNILLERIA NO TE LUCES

[@kroliki-kolxoznu]

Здравствуйте. Подскажите, а цепь привода, не слишком близко расположена к резине ведущего колеса?

[@thunderstruck1078]

How did you figure out this was the right sprocket ratio? I guess some formula involving motor's RPM and wheel radius or something like that.

[@victorwild3225]

Why not use the sprocket as a brake disc?

[@DonnDIY]

I considered this but was afraid that brake pads would get contaminated from the chain lube that's stuck to the sprocket.

[@victorwild3225]

Quite possible but I would have thought that centrifugal force would keep it clean

[@victorwild3225]

Or go for belt drive

[@heliarche]

I've gotten bit by the jaws on my lathe plenty of times and I'm sure I will get bitten again. Your lathe looks like it would gladly take an arm if you give it half a chance. I'm not trying to be Mr. Safety. That's just my way of saying I love your machine.

[@DonnDIY]

No doubt - one has to respect his lathe and be careful around it.👍

[@opendstudio7141]

Part flinging is not allowed. I bet you don’t do that again. 😉 Question: Have you seen a ROKON trail breaker bike? From the website pictures, you can’t tell how the front wheel works.

[@DonnDIY]

If it's the 2WD bike then I've seen it yes. At some point I was really into 2WD motorcycles. Maybe one day I'll be into them again.

[@Dieselfan700]

Are you planing to use bushings inside the hub? to avoid force on the berings when tightening the rearaxel?

[@DonnDIY]

Yep, of course.👍 I just mocked it up so I could see whether the brake rotor and sprocked flanges were ok. Now I can finish it up by making the spacers.

Isn't your engine going to spin the wrong direction?

[@DonnDIY]

Good question👍but no. The engine crankshaft rotation is counter-clockwise.👍

[@warhound7781]

Love the build. I feel the brake caliper is overly exposed though.

[@DonnDIY]

It is a bit on the exposed side but also freely accessible, making maintenance easier.🤷‍♂️ Mounting the caliper to the frame is also much easier.👍
