10 Meter airgun range with target trolley installed. Or not.
Shop Attic is 6ft W x 41-48 H.. do you utilize this space?
the few things in this attic are still here from the previous owner.
my shop's attic FLOOR is going to be sealed and insulated this year and i was thinking about adding a pull-down ladder entrance and adding a basic floor with reclaimed deck wood.
this would be a space i can only crawl. I don't plan to store things here, but plans change.. i was just looking for a way to inspect this attic on occasions.
plans do change, so i was preparing it to be a storage space, if need be for the right things.
now i see i'll have to offset my pull-down ladder so that the ladder top is near the center of the attic.. would this be the right placement?
do you utilize such a short 41 inch high space that's 6ft wide? (it's 48" to the roof deck)

i appreciate all the answers and slept on it.
since i need to crawl in there instead of standing, i think i'll still need to get up there and lay some boards down so i can apply scabbing to the broken rafter in the previous picture, review wiring and electrical boxes before it's insulated, remove this weird anchor hanging from my ceiling, mount a couple ceiling fans, and someday staple radiant barrier to the rafters.
the previous owner did some questionable things and i wonder how many sins are up in there which i cannot see. lol
with the observation from @lugnut i'll not be storing anything up there.
Yeah, me too... My wife told me last night (again) I'm a hoarder
Maybe a little bit, now that I see my son not throwing anything out... ever. Funny how kids are mirrors
I did something similar, only my trusses are 6ft tall, and I have 5ft of headroom.
-Check all trusses to ensure they are sound and make any repairs to restore them to original working condition.
-Reinforce the bottom chords of the trusses by sistering a 2x4 to each one, extending it beyond the bottom panel point each way.
-Use 1/2" plywood for the walls and 3/4" plywood for the floors, this way the trusses act together and better distribute loads.
-Store only light materials. 10lbs per square foot max.
I analyzed my trusses (chords, web members, connections) to ensure nothing was overloaded. If you can't analyze them, then compare the new loading (dead load + Live Load + Storage) vs the original design (dead + Live) and make sure you are not more than 5% than design. You can compare total load on a single truss for simplicity, or also the bending moment as if it were a simply supported beam. Since you are only loading 3~4ft of the span with 10psf, you'll likely fall below the 5% rule.
