Joseph - thanks for the detailed feedback! I've been working on a plan for my new system, and this will help a great deal.
My rack might be a limited version of yours. And, b/c Im not sure how well it will work out, Im thinking of starting out with a basic structure and then building it from there.
- Couldnt find much on pulley's in my HD or Loews so far, especially that ratchet pulley. But, no big deal as I think Im gonna add that later. I completely get your point about locating the connection points on the ends of the rack. thanks in advance!
- Very glad I can cut all of these with a mitre saw. I have a 12" saw just purchased last year. Will save alot of time vs hand cutting!
- I'll follow your directions on the riveting as well - thats what I was looking for since there's no "user manual" out there for Beginner Riveting.
For my design, all I need, I think right now, is an aluminum rectangle to hold the T5 EndCaps. Im hoping a single frame will be sturdy enough to hold everything.
I essentially wanna mimick my current rack which I made out of 2x3s. Yes, can you beleive that! Its been doing the job for 7+ months, but now its time for a change (plus I had an endcap break, so its good timing).
Here's what my current, wooden one looks like. I have 8 60" T5 lights that I need to cover 72" of tank surface area. So, I stagger them 6" on either side:
Its been working out pretty good and I cant think of any better way to set it up.
So, Im thinking going with the same design with the aluminum tubing:
- 2 x 72" of 3/4" tubing for the lengths
- 4 x 24" of 3/4" tubing for the width/depth
- secured by flat straight and angle pieces on the tops and bottoms
Here's a rendering of the box fram, out of the 6 sections of 3/4" tubing:
And then securing it on the top and bottom with flat pieces and rivets:
I will mount the endcaps to the bottom of the 3/4" tubing width/depth pieces. The ballasts will be kept seperately for now. And, in the time being, I will suspend it from the ceilign using simple eye hooks and chains, the same that are holding my bulky 2x3 wooden rack now.
I'll tell ya, Im not an engineer like alot of you guys, so let me know if you think this will hold.
