Hey, I’ve watched most of these if not all. Thanks for putting this together. I want to build a similar apparatus to raise and lower a screen. Do you have a link to something that could be purchased similar to your L attachment (trunnian) you cut to make work?
I would use a set of pillow block bearings like these:PGN - UCP205-16 Pillow Block Mounted Ball Bearing - 1" Bore - Solid Cast Iron Base - Self Aligning (2 Pack) www.amazon.com/dp/B07MWGF35D/ref=cm_sw_r_cp_api_glt_i_7SEHQ547Y57TPVK6QY16 Just make sure the bearing bore matches the outside diameter of your pipe. Happy building 👍
The "bearings" I used for the bar were from a pick-up truck bed unloader. You could use pillow block bearing instead, just make sure the bore diameter matches the outside diameter of whatever bar you are using. Example: www.amazon.com/PGN-UCP208-24-Mounted-Bearing-Aligning/dp/B07QMGQNLM/ref=sr_1_4?crid=366MB7H2NRKFY&keywords=pillow+block+bearing&qid=1645222251&sprefix=pillow+block+bearing%2Caps%2C129&sr=8-4 The chain drive components can be purchased at Tractor Supply or any farm supply store.
@@TheLawnEngineer thanks, my screen is 15’ wide and I keep having sagging issues (currently using 2” diameter emt conduit with a 2” dowel rod (inside) in the middle (screwed to the pipe). Currently stand on a ladder and hand roll the screen up but would like to get something like you have to raise and lower. My struggle has been finding something that doesn’t sag. What I’ve learned so far is that the bigger the diameter, the better. Which makes finding a crank mechanism nearly impossible.
@@louispounds7486 Yes, an increase in diameter has the most impact on stiffness followed by wall thickness. You will likely have to move from conduit to pipe but finding it in lengths over 10' may be a challenge. You should be able to find some chain drive or v-belt components at a farm supply store to work with most reasonable diameter pipe. Awesome screen size through...15' that's awesome!
Cool. Working on this cracking mechanism
I’m glad you found the correct video 👍

What is the distance is from the projector to your screen? I am planning to get 120 x 96” screen, slightly wider than yours. Thanks in advance.
This video should answer all you questions on layout. ruclips.net/video/RyN72yNRj8c/видео.html
Good luck with your build!
Could you share a parts and pieces list so that I can build the roll up mechanism, thanks in advance
I'll have to put something together, I'll let you know.
What material is that impact screen? Where did you got it?
Check out Episode 2. I talk about the screen and there is a link in the description.
How and where did you find the mechanism to lower/ raise the screen?

@@TheLawnEngineer thanks, and yes, loving the screen size!! It’s definitely a work in progress!! Thanks for responding!
@@louispounds7486 you’re welcome, I like hearing about what other people are working on. Have fun with your project!
Drill?
Yes a drill could replace the hand crank.
