You were able to get alignment on the BN220s? My axle holes were slightly misaligned with the hole on the mount.
It didn’t align perfectly for me. What I did was put the shoulder bolts through the axle hole, then firmly screw in the shoulder bolts. Once I did that, I slid the caliber adapter along the axle until it would not move further.
I haven’t removed the shoulder bolts yet, so we have yet to see how well this plan worked.

#yolo build guide
Step 4: mounting the housing to the caliber adapter
Tools: 3mm hex key, eyeballs
Start by sliding the housing onto the adapter. Once the housing is flush with the caliber adapter, align the three mount holes in the adapter with the holes in the housing. You will need to eyeball what angle works for your board. I’m using a vanguard with risers, so I angled mine at about 15 degrees. Use 3 #2 bolts and #5 Lock washers to secure them together. I did not loctite these initially as I’m not absolutely sure the angle is correct.
Step 5: mounting the motor
Tools: 3mm hex key
Find the red motor mount plate, it is individually wrapped with the bergmeister adapters. Place the shaft of the motor through the central hole. The grooves should be facing up. Align your motor so that the cables go towards the small side and the motor mount holes align with the grooves. Take 4 #9 screws and secure the motor to the mount plate.
Step 6: assemble the motor thrust bearing
The first thing we need to do is mount the thrust bearing to the shaft. The thrust bearing comes in three different pieces, the ball bearing holder, a tight washer and a loose washer. One of the washers will go on the shaft easily and the other will not. This is very important, so make sure to get the order correct.
The loose washer goes on the shaft first with the circular raceway facing out. Then the ball bearing holder goes in. Then the tight washer goes in with the circular raceway facing the ball bearings. The tight washer can be very hard to get on the shaft, the seems intentional.
Step 7: mounting the motor gear
Tools: loctite, 2mm hex
Now that the thrust bearing is in place, we can mount the motor gear. Take one of the #7 keys and carefully place it into the motor keyway with the flat face up. Slide the motor gear onto the motor shaft until it is flush with the thrust bearing. Apply loctite to the grub screw hole. Use a #3 grub screw to secure the motor gear in place.
Step 8: mounting the motor part 2: electric boogaloo
Tools: 4mm? Hex
Take the whole motor assembly and place the motor gear through the large circular hole. Turn the mount plate so that the cables go over the top of the housing, and the holes on the plate align with the holes in the housing. Use #8 regular washers on #12 bolts to secure the plate to the housing.
Step 9: aligning the wheel gear
Tools: eyeballs, gear lubricant
Apply lubricant to the teeth of the wheel gear. Take the wheel gear that we assembled in step 3 and slide it over the axle and caliber adapter with the gear teeth facing towards the motor gear. Pus it in until it stops while turning it slightly. To check alignment, hold the motor still and rotate the wheel gear. It should rotate just a tiny bit back and forth.

Give Morris a break. He just completed what is effectively a huge project, designing, engineering, and testing a complicated drive system. That project had a staff of two people, Sofu testing and Morris doing everything else.
Morris can afford to take a break for a bit.
@sofu has just been casually dunking on people for not figuring out how to set it up on their own instead of offering any help to my knowledge.
I don’t mind picking up the slack and making a set of instructions for everybody else.

Yeah, let’s just ignore my previous comments about things to watch out for during assembly as well as literally all my posts throughout the entire testing process you can reference and just say I’m only here dunking on people.
There is actually an old assembly video that people can maybe reference but the design has changed so much that much of the video doesn’t apply anymore, so it’s not public. If @MorrisHsu wants to make that video public he can do that

All I’m saying is I haven’t seen much going on with this gear drive in months.
Morris completed the design, manufactured the parts, assembled the kits, and shipped to the people who ordered it.
Read through the last ~75 posts to find out those details.
I have read through everything. Why are your panties getting in a wad over this?

So my original plan for using this drive with boardnamics trucks did not work at all.
What I ended up doing was taking a metal file and filing down the top part of the hanger until it aligned correctly and the bolt could be inserted easily. Then I carefully tightened the caliber adapter while checking the alignment constantly.
I reassembled the drives and it works perfectly.
One additional thing I did a while back and forgot about. I bought 60mm shoulder bolts from McMaster Carr so that they fit correctly with no spacers.

There should be washers on those screws on the inside.

@sofu & @Winfly Props for all the testing and helpful build tips, it’s great reading through your builds and thoughtful contributions to the community.
@NullReference - Appreciate yeah writing this up with the further detail, photos and tips.
@MorrisHsu - Holy fuckballs these are beautiful. Thanks for sharing this project and making it available to the community.
@AngryTrucker - Saucy
@Kellag - If you don’t like them, then don’t support the project but enough dragging down the conversation small petulant child.
@Myke - I expect more from Spokane - your title is fitting - Spokane the fuck up.
Esk8 love and shit - Looking forward to putting these bitches together.

Wtf are you talking about? Mad because this project fell of the face of the earth and I said it out loud?
So you have a set of these gears to show all your support to the project??
