Hi Tim
You might want to put this question in the DIY section.
I’ve built or help build a few equatorial platforms. I think they are a great project certainly much cheaper to build one than buy. There are a lot of designs out there. If you are a wood worker and have a table saw or can build a jig then I think Ed Jones’ design is excellent. See these videos:

If you have access to a 3D printer then there are some designs on Thingiverse. This one looks interesting:

Here is an old thread from here that includes some photos of one of my platforms:

Let us know what tools you have available to you and your level of skill and we can probably help you better decide what would suit you.
