With a Precision-Shim in between, insert a Wheel-Bearing into either side of the Solid-Wheel.
-
It may require some force to seat both bearings fully.
-
A good technique to assemble the wheels can be found here: https://www.youtube.com/watch?v=Zbh1HF6l...
-
Repeat this for 30 Solid-Wheels in total.
-
There is one spare Solid-Wheel, do not assemble this one.
-
-
-
Put all the Solid-Wheels in a box/tub for safekeeping, they will be used throughout the upcoming guides.

Hi Michael,
We have a printable cheat sheet here: https://ooznest.co.uk/wp-content/uploads...
This has every box the parts can be found in.

I like the fact that the build is so ( nuts and bolts ) when stuff goes wrong you know the machine in side out, you built it
simple enough
To be honest I think this is a step in the build process I could do without. Yes I know its about keeping costs down, but I found the seating to be a bit vague. Some went in with a satisfying click, others not. Some required a lot of force before they were truly seated. I ended up checking each one several times because, I imagine, get this wrong and you are building in an issue that it would be difficult to get past.
Hello and thank you for providing good instructions on assembly. The only change that I would make to the instructions would be to have a parts list for the steps . With that in mind, I did make a video illustrating the parts per step that I hope may be of use for others. https://youtu.be/0_SxWLAK_wA
The suggested guide for assembling the wheels is first rate.
I watched the Erie guys video and it was helpful. Being in the states, I didn't have a 5mm screw laying around, but a 3/16" drill bit and a couple pieces of wood did the trick. One piece of wood had a through hole, the other with a blind hole, both drilled with the 3/16" bit. After boring the holes, the drill bit shank was placed into the blind hole. Then, like in the video, you stack the bearing, shim, wheel, & second bearing onto the drill bit followed by the second piece of wood and squeeze the assembly together. Worked like a charm.
Does the shim (washer) have to align with the bearing or it is actually just acting as a shim/spacer? i.e. Is something go all the way through this at a later stage?
Hi Ben,
The shim would need to be aligned, this is because a bolt will be placed through the wheels further along in the guide.
Thanks.
Hi Donie,
Step 4 in the introduction here: 1. Introduction
You can download a cheat sheet, which has all the box names the parts are in. Hopefully that helps!
Thanks
I lined up the shim by tapping home one bearing and inserting a bolt ,dropping on the shim and no2 bearing, flipping it all over into a 7mm hole drilled into a scrap bit of wood and tapping the bolt. Bingo . my ancient damaged fingers saved and all done
Nice, thanks for the tip!

? Thanks step one and I need help?
I only received 59 bearings instead of 62 in the plastic bag.
So I used the chat to contact you.
Waiting for the answer on monday. ;-)

Hi Alain,
I see we have a ticket with you regarding this issue, we will get this sorted for you.
Thanks.

i can confirm sore thumbs. unfortunately no matter how much i press some the bearing does not fit perfectly square and there is a slight wobble. not sure how to get around this and if this is detriment to the running later

Hi Richard,
Take a look at this video at 1:50 - https://www.youtube.com/watch?v=Zbh1HF6l...
Good little system on how to assemble the wheels.

This does require a bit of force and my assistant found his thumbs hurting ;-) We found that if we threaded a bearing/wheel/shim/bearing along an allen key that centered them nicely and then we used another allen key at right angles to the first one to pull the bearings into place. When done this way the shim seemed to be solidly fixed between the two bearings and my assistant’s thumbs hurt less!

Do not worry about the precision shim not being centered. It will be able to move later, often when pushing a threaded screw through the precision shim centers. Sometime you need to rotate the wheel (like threading it on the screw). At one point I needed to pushed a pin down to center the precision shim to get the wheel on the threaded screw.

Hi Emil,
Thanks for the tip. Sometimes spinning the wheel on the bolt helps the precision shim get into the correct position also.

@robthompson My precision shims were in a (labelled) bag in the “Brackets and Spacers” box

Haven’t got any precision shims but there is a spacer in the wheel, is this instead of shims?
