Hi Jared and welcome to IIS , I like Matt and Zero also love ATM'ing , I have built about 10 Newtonions from 4 inches to 10 inches and one 127mm f8 iStar lens sourced refractor over the years and totally enjoy it , the only part I have not made are the secondaries , they are cheap enough from Bintel to not worry with and the low profile helical focuser in my 10 inch f10 .
Here is a photo of 6 of my newt builds and the finished iStar , hope it helps
, its a great hobby that is so rewarding .
Don't hesitate to ask any questions if you get stuck , anything goes mate .
edit , the purple one in the first photo is a 6inch f8 that performs very well .
Brian.
