This is my first Instructable. I didn't plan ahead for it so it is light on photos. I thought it was worth publishing because a few of the steps I took can be applied to other projects.
I was inspired by this project:
Produce (or Purchase As I Did) Edge Glued Panels

I bought premade edge glued panels at a local quality lumber store. I did that to save one step and because it can be difficult to end up with panels that are nice and flat. The ones I chose are Spanish Cedar. I chose a softwood because for some of the operations, hardwood would be really hard on tools.
Glue Panels Together to Form a Stack

For this step I anticipated that trying to glue 5 layers together would be difficult, with the layers sliding around on the glue while clamping. I am an amateur. So I clamped them while dry and drilled holes to use to bolt them together. I don't think I would do this again. It was really hard to get the bolts out after the glue dried!
I almost forgot an important detail. When putting together a stack like this you need to alternate grain direction. Horizontal first layer, vertical the next. This is what provides strength and stability.
Cut the Desired Shape

![PXL_20201219_222440347.jpg](/proxy/?url=https://content.instructables.com/FOT/2F07/KKB5IWSQ/FOT2F07KKB5IWSQ.jpg&filename=PXL_20201219_222440347.jpg)
Use a band saw to cut the shape. Then use a disc sander and an oscillating spindle sander to refine. I don't have these tools so I found a local wood shop that rents space by the hour.
Drill Holes for Planet Rods
![PXL_20201220_190244157.jpg](/proxy/?url=https://content.instructables.com/FLV/UE8H/KKB5IV5O/FLVUE8HKKB5IV5O.jpg&filename=PXL_20201220_190244157.jpg)
I wanted to drill these holes as accurately as possible. Drilling by hand would not do, and there was no access to use a drill press. So I made these single use bushings from scrap pieces of wood.
Add Planets (or Whatever)

I purchased the wood balls for the planets from a vendor on Etsy.

I used watered down acrylic paint to color the planets. Then I used Tung oil or similar to give them a low gloss.
1/8" diameter brass rods are easy to find online.
I hope this gave you some ideas. If not I will never post again! JK
Addendum

It was pointed out that I didn't include any dimensions. Actually the whole post is light on details. But here is a drawing I worked from. I did the design using the CAD program Rhino.
