What in the World are these?
These are “Udie’s Wheel Mounting Spacers“.
I took a used gift credit card (or you can pick up a couple new ones at any vendor who offers gift cards).
Cut it into strips – drilled a 1/2" hole in the centre of each strip and then cut the bottom out as shown in the centre piece.
Here is what I started with.
How are the used and why are they necessary?
They are used when attaching wheels to a vehicle.
It does not matter if you are using a pass thru axle or axle pins/pegs, the problem remains the same.
How do I get a space between the back side of the wheel and the vehicle’s body to allow the wheel to spin freely and hold it in place while the glue dries?
Place the Wheel Mounting Spacers on the vehicle so that the cutout is around your axle hole.
If you have already mounted fenders and other details, then cut the spacer to fit your needs.
The opening should then be facing the top and not as I have shown facing down.
You need a way to remove the spacer after the glue has set; you have to slide it out from the bottom.
The spacer does three (3) things for you.
It provides the gap necessary for a free spinning wheel and provides a flat surface which the wheel will rest on while the glue is setting.
And, if there is a little bit of glue squeeze out, the glue will not stick to the plastic.
To ensure the glue squeeze out, if any, does not glue the wheel in place, rotate the wheel every once in a while as the glue is curing.
How thick is the Wheel Mounting Spacer
This gift card is 1/32” thick.
More than enough for a free spinning wheel using an axle pin/peg or pass thru axles.
If you wish to reduce this width, then all you have to do is find some thinner material to make your own spacers.
In use example.
Here I am gluing the wheels to the Rockin' Rollers Freaky Ford.
Do not assume that I am mounting the wheels using axle pins/pegs.
In this case I am not.
The wheels are mounted to a pass thru axle and I have cut the tenon length of the axle pins/pegs short to add the hub detail.
Give it a try and Happy Toy Making!
