Update thru October 3.
Got the wood racks painted. So far, I'd not had to move these frames solo. On Wednesday the 29th, I got my chance. I attached a couple of 2x4's across the trailer and moved the racks one-by-one to the trailer so I could wire-brush the surface rust off and clean the oil in preparation for painting.
Boy, are these things heavy! According to the tables, each frame should weigh about 108#'s. 100 #'s is no big deal to lift, but when it's spread out across 12' in length and not evenly, it becomes a chore.
I took the first frame and laid it down on the trailer with the arms standing up. Then I clamped it to the trailer.
Added the remaining frames and began the laborious task of removing the scale and rust. I had a variety of tools to use, none of them ideally suited to the task. Couldn't find my small right-angle grinder to save my life, so I resorted to using my homemade flex shaft grinder with a flapper sander. That worked OK until the cable broke, but I'd managed to complete 5 of the 6 before this happened, and my little cordless drill got me thru the last one.
I ran through a ton of rags and about 1/2 gallon of acetone to clean the oil and crud off... Took the better part of 3 hours to get this work done.
It was a good thing I clamped the first frame to the trailer, because about half-way through the work, while shifting the stack so I could get at another frame, I bumped one and 3 tipped towards the clamped frame. The clamp held and nothing went crashing to the ground.
Then I had to move them into the shop for the night so they wouldn't rust again in the morning dew. This is the same shop that has a total of maybe 10 square feet of floorspace. Finding enough floor space, then clearing it out, and staggering in the door through the obstacle course to the free space was another PITA.
Thursday, I got them painted. Had to move them again to do this work, but this time it was one at a time. I'd move the frame into place, flip it shelves down and wire-brush the rust off the back - the part I couldn't get access to on the trailer. Found an old two-speed craftsman 6" grinder that worked like a champ, but the gear case is leaking oil and the sucker makes a horrible racket. A final quick scan for any missed rusty spots, and a second cleaning after that with new rags and more acetone.
Painted them a nice blue in Rustoleum with a roller. First application had bad holidays in the paint, but after the first coat, a light re-roll over the entire frame evened the paint out to a nice finish. Shifting them from the painting rack to the drying rack was done with a pole in the top and me holding the top shelf arm, and a pair of vice grips clamped in the bottom end on the back side - very carefully.
Here's what they looked like all decked out in their new paint:
And a view from the stair landing to the loft:
Saturday, we got them installed. We attached 3 2x4x12's to the wall at the floor, 72" up and about 138" up on the wall to serve as mounting rails for the frames. These were lagged into the studs which are 24" OC with 3/8 X 3-1/2" lag bolts, countersunk into the face of the 2x4 about 1/2". With the sheathing, that gives about 2" of solid penetration into the wall stud. All holes were first counter-bored with a 1-1/8" spade bit to allow for the washer and the lag screw head, then thru-drilled with a 3/16" drill into the wall stud as far as we could go. Then the 2x4 was overbored with a 3/8" drill.
Just to be careful, we also laid a 1x4 on the floor in front of the bottom mounting rail for the bottoms of the frames to stand on.
Originally, I was going to place them 2' on center, for a total run of 10' (6 frames at 0, 2, 4, 6, 8 and 10 feet). Tin suggested I was being over conservative with the spacing, and we had the space for a larger span. After looking at it, I agreed, so we installed the outer frames first, each about 2" in from the ends of the mounting rails. These are attached with 5/16" x 4" lag bolts, with the 2x4 being pilot-drilled with a 3/16" bit.
After the first frame was installed, I had Tin watch from along the wall as I hoisted myself off the floor by hanging on the bottom shelf. I weigh 240, and even with a bit of dramatic bouncing and wiggling, Tin observed no movement in the wall.
The remaining frames were installed, and we checked for even elevation across the shelf arms after each frame went up. I'm not concerned that the frames are level from frame to frame, only that they're plumb in all directions. So long as the elevation is consistent, if it trends uphill or downhill a bit, no worries. We only had an issue with one frame, which was about 3/32" lower than its pals. We shimmed it up with a couple of 3/8" flat washers and got within 1/32" - more than good enough.
Here's the picture of the frames mostly installed:
And here's the group fully installed:
And here it is FULL of lumber:
All of the top shelf and most of the 2nd shelf is lumber I got from my great uncle (same one I got all the unusual tools from). The top has about 60 pieces of t&g 1x4 clear pine from his parents house which was demolished in the late 1940's. The longer pieces are 16'+ feet long - there are about 70 of these, and there are some shorter 10' pieces, about 30 in number. They're sanded smooth on one face, and that has paint (probably lead-based). The reverse is rough-cut. This stuff is no longer fit for use as t&g wood, as all the tongues & grooves are a mess (no care was taken to preserve this feature when they were removed from the house). However, in all the 1300+ linear feet of lumber up there, I don't think there's a single knot. We only had to toss one piece that had a nasty crook. The rest are straight as an arrow. Tin just rolls his eyes when I say things like "that kind of lumber isn't available anymore at any price", but it is true. Have I got plans for it? No. Will I ever use it? Maybe.
2nd shelf has some odd bits 'n pieces. There are a couple of pine boards that are from a cabinet somewhere. They're about 72" long and 16" wide. Old stuff - still flat with very few knots. I've got 6 or so 12' 1x6 heart redwood, plus a 12' 2x6 heart redwood. Beautiful straight-grained and knot free, and light as a feather. Some really old oak, and a couple of pieces of maple too. There are some boards that look like batten from a cabinet back. They're about 3/8" thick pine that's quarter-sawn... Somewhere in that pile is a 1x8x12' piece of beautiful Fir - no knots and quarter sawn. My uncle didn't have what he believed to be "fine" wood. When he accumulated it, it was just "lumber" to him.
The third shelf is the mixed lot from my various projects. Poplar, maple, walnut, cherry (my favorite wood) - even a nice piece of Wenge.
Last shelf is all structural lumber - just standard fare. Much of it will be used to build some shelves in the loft.
The good part is that EVERY LAST STICK of hardwood that's more than 3' long is in the rack. We took a plumb reading on the middle frames with a level before we started. Watched it as the rack was slowly filled up, and checked it at the end. There's probably well over 1,000#'s of lumber up there, and the total deviation on the "plumbness" - by my eye - was less than the thickness of the wall of the bubble...
The final item for the rack is a set of 4 shelf edges. 2" x 1/8" angle that will be attached to the ends of the arms. I'm going to fashion some 2x blocks that have a gradual taper and drive them into the ends of the arms. Then I'll use a 1/4" lag screw driven into a too-small pilot hole to wedge the block in the arm and hold the angle up. This will allow a ladder to be propped against the shelf for access to the lumber without actually bearing on the contents of the shelf. That iron is being cut today, and hopefully it can be installed next week.
This weekend is occupied with a project for my former landlord, where the old shop was. In earlier threads I noted that we were lucky enough to sell the entire contents of the interior structure to him when we left. Our lease allowed for its removal, but selling it, even at a strong discount, was a far better deal. Never finished that space like this one, and now he wants to convert it to office space, so we're finishing up the walls, etc. That's gonna take a couple weekends to complete, but should bring in some $ to offset the sink-hole expenses in the new space.
His dad is a retired HVAC contractor, so I'm thinking I might negotiate a trade for a new furnace and A/C for our shop in exchange for our work...
We shall see.
