I just got the news.....Like we needed another reason to loath 2020. RIP Jackson.
Condolences to the family & all his friends. World class guy. Sad.

hehe, I drop by to see if there is anything interesting (to me at least) & I find My old friend Arlo1 still Building cool stuff.
Bravo brother. I needed this today.

yes, physically (into the direction your spinning the rotor). Easyest done with external hall set up. For internal placement, I started using "between the phase prs" for positioning & payed attention to rotation to have the advance going in the correct/desired direction. (if my math wa...

Dan, In my experience, my best overall setting for hall timing was between 3 & 5 degree's advanced from lowest amp draw unloaded. you will get some stutters at the extream load (starting from a dead stop) but this should wake the motor up from 1/3 speed to the top. Idealy these motors are produc...

These might be old news but seem like the answer to this challenge. Description says they fit on shimano splines. whoa....those are free wheelers. sweet, but: " Will you please let me know if this freewheel is compatible ( fits)with the shimano freehub if not , what hub is this freewheel compa...

That's some lovely modeling. free advice: You may want to add some "cush" to your design to help absorb the load spikes to the system. Are you thinking of a grease packed primary reduction? small gears are great for light loads, but do the math when scaling them to bicycle/light moped appl...

From a casual glance, I suspect the winding on that stator tooth as defective. or was damaged. Q?-has that motor ever run on any other controllers for a period of time? In an over-current event, I would expect to see more discoloring of all the windings involved. (that would be the adjacent tooth &a...

you can't get that thing in 3rd gear in that room......

I am with recumpence on this one also, BMX chain is tough...& the 418 heavy duty (still bicycle) chain is tougher yet if you have any concerns. #35 is great if you need finer gearing choices, is less expensive than "premium" grade bicycle products, but you will be fabbing more "sp...

Highly regarded....lol, (thanks) I could/should have been more clear, putting a freewheel on the driven end of the reduction introduces quite a bit of "play" in the drive set up... if you put the freewheel on the driving sprocket you will reduce the hammering on the pawls. & this is wh...

For lack of a better place to post this:

Hey Amberwolf,
Havent made time to play with the wax filliment yet. Busy season at work has me tied down 50+ hours a week.

I'll make a point of looking for something to print & cast (prolly something simple LIke a ring) & post it up.

If that's a Skyway Wheel, they have limitations to max pressure.
My 20" wheels have came with a sticker 60# max
my older 24"s have it molded into the rim.

Also - I plan on donating 1/2 of any profit to Vedder - this is his work, not mine. I'd like a few bucks for my time and shipping materials. I expect i'll get $5-10 maximum each (split w/ Vedder) which i hope to put into a reflow oven. I have about 20 extras. I've already donated 50 euro to Vedder ...

Gorgeous as always Matt....but you need to take 5 minutes & program your camera.....or is it really Jan. 6th 2003?.

I didn't know where to put this interview with the Alta creators....& some good footage of the bike in action...I still say it needs to lose 50#s but its looking better every time i see it in action.

you could blow torch it off....

but its a option for gluing on an adapter on threads that are not favorable to left side drive.

metal re-enforced epoxy...
look at dp-460

Another perfect example of no one reading the op..... Does any one here think the KTM in that video is anything other than weak sauce? (or remotely competitive with a modern 4-stroke 250cc ice on a real course?) You can spout off about single speed all day & be right.....but no one can produce a...

Its lovely.
I am curious about the ratio spread.(current design & the min/max potentials)
also looking forward to some section & cut-away renderings.

thanks Miles.

on topic: JLdp1Kz0naI E-motocross is coming.....There is some incredible urban motocross potential if we could stifle the noise a good race bike makes. the KTM in this video is so close to being there (except in price)...not a frail bicycle conversion.....but really, still no match for a 12 year old...

Moto, You are trying to mix oil & water.... I went to a national motocross recently (Hangtown) and I noticed that every rider is revving there engines getting every ounce of acceleration out of their bikes. revving does not make acceleration in of itself....they are only revving the motor to get...

whooo whoo
My wax filament delivered today....time to figure out a strategy to keep the slippery stuff on the build table.

I am thinking a coat of pva followed with a spritz of 3M77....stay tuned.

for anyone looking for printing wax....

Thanks for the compliments & input. I've continued to challenge myself & am getting more comfortable designing printable parts. I commute about 45 miles to work every day...last fall they paved a really nice bike trail I can access for the last 15 miles of the journey. it goes through some r...
