« Part 2: Oh no, the kids are on the power tools. Part 3 of Awana Grand Prix series Part 4: Wheels, axles and wheight »

When we got the block of wood for the body, they were totally out of square. We took them to the
shooting board to square them up.

For an example of a shooting board, look at the widget below.

Or you can use a table saw to square up your block.

The shape of the car was completely up to the children, I like the skating board the best for the race my self, but don’t tell my children this.

The next thing I was looking at was the positioning of the wheels, where to put the axles. I did not like the slots the block came with. They were not perpendicular to the block, and not in the location I wanted them.

I like the wheels as far forward as possible to give the car stability, but keep them just a little back from the front to keep the wheels from hitting the stop at the end of the track. So I put them 3/8” from the front. I like the cars as low as possible, so for this I went to the paperwork with the kit, the bottom of the car 3/8 up from the track.

It as all about reducing friction. So 4 wheels on the track is good, 3 wheels might be better (raise one up by 1/16”). I will not do it this year, but I have raised cars on 2 wheels. The problem you run into is balancing the car, but also balancing the car on a slanted track. This year we will go for 3 wheels on the track.

For drilling the axles, I set up the drill press with a jig with stops for left and right to keep the holes all the same and also so my children can do some of the work. The drill press is set for depth too.

Here is a progress picture of the shaping and pianting of the cars:

The race is Friday, check in is Wednesday, so I better keep going.

Wish me the best, Pabull.

Mads, there is no better time than with the kids in the shop. And the results are great. Thanks.
Dennis, I will keep you posted. But don’t start crying yet.
Autumn, it’s a lot of fun when you do it with your OWN kids.

Be well, Pb.
