The one diagram has all measurements on it, material is 1" thick. I will make a over all cut sheet when time allows.
For longevity I would suggest using a hard wood.

Um, I decided to give it a go, but got nowhere. Am I correct in thinking that the legs are about 6" wide and 2" thick? To make those would require an 8"x4" piece of lumber. Kind of hard to come by, unless I glued several pieces together. If, as you state above that, the pieces are only 1" thick that is doable with an 8x2.

Also,an orthogonal projection would be really nice as well.

Thanks for the plans Gabby. Looks really interesting. So far I just use lawn chairs which I stack to increase or decrease the height of my perch.

All of the dimensions are listed on the plans, the largest piece is the backboard which is 6" x 52"
Legs are 2" x 1"
All material is 1" thick.

OK, thanks. I will re-review the plans then. It looks like a nice design!

Thanks - I hope so. I'm hoping that with a seat people will take longer to LOOK! :)

If you are going to be having multiple people using the chair during a session I would suggest fixing a piece of light chain in the indicated location to prevent the leg moving back.

Thanks! I had thought of restraining it - a chain makes more sense than a solid wood piece.

I like the chair plans. Nice build Star Dad. Why do you call it the "Denver" chair? I basically live in Denver and I have never seen one ;)
Recently I have been doing almost exclusively Solar viewing. I have two Lunts a 40mm & a 50mm which I can triple stack. One to use for imaging and the other for visual. Two Lacerta Herschel Wedges Big & Sm with 120mm & 95x1300 refractors using go to alt/az mounts and my big goto EQ.

Hello !
Fine work, and very useful !
Speaking of "Denver chair", it seems that Denver is an creative city. In France, we have "sabot de Denver" (literally "Denver clog"), with a clear use :

There are a few different variations of the chair with one popular one being called a Denver Chair.

Yes but they can move both way so better a sturdy piece off wood , during lock down I built a few from pallet wood the first I used some rope but during testing was not a pretty sight , fortunately much lower as it was for a 10inch dobs
I see their is a solid brace on the diagram !

Oh, yeah that dastardly device I was one of their first targets! they followed me to work! then Booted me as I got out of my car! Only one, over due ticket! It is a great deterrent, I pay all fines fast now! that was in the mid 1980's I haven't been "Booted" since. If only our Boots were wooden.
