Same favs as a kid for skateboard and roller skate baseplates. @akhlut hell yes! @MD84 Watching this one with a jealous heart. Good stuff.
Quick update, I slapped on my daughters 75mm big zigs. Went for a ride trying forward and reverse mounts at various angles.
Holy shrimp! Those big zigs are pure joy. Too bad I can’t slap a pulley on those…
I didn’t really have any problems either way. I tested rolling up a rounded curb that my evolve will sometimes rub if I’m feeling extra heavy. The mount actually had more clearance in the forward position.
At this point I am going with forward position at this angle:
So I’m going to narrow down the wheel diameter to either 76 or 83mm
How do kegels compare to flywheels? The pulley adapter seems easier to make…

So cool to see you using a Earthing DH deck! My roommate and I are huge advocates of Brain’s business. Those decks have amazing concave. I’m looking forward to seeing your board up and running so keep us posted. Also on wheels, if you’re ambitious you could try the 76mm abec flywheel in classic thane. I haven’t seen anyone use them because they force your drive system to be crazy low to the ground but I think you may like them because it seems like you want a more traditional board height and riding position. I just got some 83’s myself. Good luck with your project! @MD84
@GreasyGearsWRX Thank you for the motivation… I love the Earthwing brand, such a great company. My first and all time favorite longboard deck.
I’m just going to go for it and run the 76mm wheels. They are hard to find but I think I found a good source. I think I should be ok with ground clearance…If not, they will be a sick wheel for a gravity board.
Here comes some more progress…
Tap a hole for a set screw
It holds it in place ok, at least enough to for a test run later on and then I will weld it
Motor bolt pattern. Hoping the print is correct for the motor… Blue layout, srcibe, center punch, center drill, drill through, chamfer

and for my next trick…
This is how you want your chips to flow…
No DRO no problem, better yet use a micrometer stop
Chamfer edges and scotch bright
…Including more pictures of the machining process

How did you make that
@moon I submerged it in de-ionized water and then burned the material away using a 0.01" diameter brass wire pulsing around 50v

Next up is the wheel adapter section of the wheel pulley
The diagram helps me on the manual lathe, The two pieces will bolt together and a bearing will be shared between them to locate them concentric to each other
Can anyone tell me if a flywheel hub is straight through or is tapered? Not sure if I need to machine the portion that engages the hub on a taper or go in straight through. Also I am thinking the larger ID of the hub is about 1.56". Can anyone confirm?

Just pulled the trigger on the 76mm wheels from Other Planet Skate
They have some interesting products, There decks look nice with a big kick tail option…

I am about to order the motor on hobby king, sk3 6374 192kv.
I found the xt90 antispark connector for a loop key. Is there anything else I need for this or anything good to get while I make a hobby king order?

Sorry I haven’t checked in here in a minute! That’s great! My roommate is about to transfer his build from a prism origin to a EW road killer! My first esk8, which I’m still currently riding, is on a 2015 EW supermodel. I’ve ridden it going on 1500 miles in rain and dirt and sand and it’s still holding up great. No warp, no delamimation, even the finish is still holding up alright. It’s good shit! I don’t know where you’re located but if you ever find yourself towards Alabama we should ride! Always feel free to tag me or DM me if you need anything!

Other than good wire and regular xt60 or 90 connectors you should be okay. You’ll need a piece of malleable copper for your loop key but you can find that anywhere locally.
I’m very excited to see how the 76mm abecs work out!

By hand? 
Or is it a CNC wire cutter?

Very nice. But how will you adjust the belt tension?
Awesome buld!

@Grozniy Good point, I originally planned on slotting the holes. Then I decided to try to get it dead nuts for a 265mm belt. If it doesn’t work out I will slot it.
Or maybe a 270 or 275 with an idler…

Finally got some time to work on the flywheel adapter section of the wheel pulley. I got the 76mm flywheels in. This made it a lot easier to verify my final dimensions. I am happy with how it turned out so far.
I made my rough cuts and then faced off the pulley side
Center drilled and turned to final size
.425 through hole
Boring the ID to fit inside the flywheel
Back to the pulley side to bore a space for the bearing
Little bit of chatter with my tiny boring bar
I still need to drill and tap my bolt pattern to join the pieces together as well as cut the slots so it will mate to the flywheel. I am still deciding which method to use for the slots. I could mill them or cut them on the EDM. Either way I need a way to index the 120 degree rotations. I have a hex collet block I think will do the trick.
The bearing presses nicely and protrudes about 0.070" out of the adapter. This allows the pulley to index onto the bearing so that they ride concentric.
I put the flywheels on for a ride and I am glad I went with the 76mm. It is a great feel. We will see how it is with the electrics…
