Inspiration: Marcus’s Steel Climbing Wall in an Old Pool

Every once in a while someone sends me some photos of their walls and a thank you for helping them figure it out. Marcus’s wall was an exception being an all-steel custom built structure, built in an old pool, and beautifully done (perfect t-nut spacing, painted, transition into a roof).

Can’t really call this one a “Home Woody”

Steel Structure for Climbing Wall

Marcus also went through the process of writing up some of the details and behind the scenes for anyone else that has a pool laying around or is curious about doing steel structures.

My parents said they wanted to fill in my pool because no one takes care of it and no one swims in it. I knew there was something fun that could be done with it so I dreamed of a way to make a climbing area out of it. 
Luckily I had friends that were able to help lend me a hand to get that gross water out
of the bottom of my abandoned back yard pool.

Pool Cleaning

I thought to myself, how am I going to do this? So this is one of the many crude sketches
I had drawn in order to convey better what I was thinking of doing to create a climbing wall
training facility in my back yard.

As I was hammering away and dreaming of my project, I ran into a friend that said he is 
just graduating architecture school! So I had him come over and do some measurements to
make a 3d model of what exactly I wanted to do and what it would look like. This is when 
my vision really started taking place.

Climbing Wall build plans

I purchased a sledge hammer and I began to smash at my concrete until I got to dirt to dig
with a shovel. This was a rather difficult task to get all four holes smashed through. 
Hole for Wall Anchors
With a little help of my metal working Uncle, I guided us to make the proper measurements
to cut my steel beams and place them into those holes I had dug earlier. This was very exciting!
If you look closely in the background you can see a string I had tied from my brick wall to 
my gate. I did this so I can measure the height of both of my support beams so that I could
cut and angle the beams on the sides appropriately. This was the biggest mental challenge yet.
I didn’t have much room for error and I did not want to waste my money or the time with 
the tools I had there available. I would say that was the biggest hurdle.

Steel Beams in Anchor points

This was an awesome moment. This was a photo of me welding on the last of the support
beams. My steel frame had finally taken shape and the very project I had been losing sleep over
was finally becoming a reality. 
Welding the Steel Structure for the Climbing Wall
I bent pieces of re-bar and tacked them to the frame as they were in their respective holes,
I stuffed the holes with concrete and packed concrete around the said rebar so that my structure
would stay firm where it is with the concrete. I then coated it with automotive primer to help
protect my outdoor steel frame structure against the elements.
Frame in Place
I had to make it look pretty! added a touch of semi gloss paint to add a more professional
look along with teal stripes for a little pazazz.. Some precise measurements were to be made from the parallel beams in order to put my 2×4  wooden beams, so they were made and I drilled 3/8 holes as straight as I could for some 3/8 bolts.
Drilling holes for wood attachments
I had to cut the 2x4x12s  very specfically so that they could sit flush with the square beams
and I had to drill holes in them so that the 3/8 bolts would go through. I had to get very clever
with the hole drilling and what I was doing. I painted my wood before I put it up to make it
last longer.
Wood during paint
After a late night building session finally I got the bottom portion dangling from the top beams! The Bottom portion of my wall finally had taken some shape!!
Wall-Taking Shape!
I was very distraught at how I was going to get my wall to go against the pool wall.
So many ways to do it, I just didn’t know how I was going to do it.. I want to spare you my 
thought processes but I ended up using a 4x4x8 and making special jig saw cuts through it,
drilled holes into it, drilled holes through it into my pool cement wall, stuck 6″ bolts through 
the 4x4x8 and into a “red head” or concrete expansion bolt deal that would hold that bottom
part of the wall to the wall steady! 
Bottom Frame Attachememt
This photo looks only slightly different! can you notice the differences? I put 3 trust beams 
going from the bottom to the unused extra beams that were sticking down. This is to help 
for just in case those two 2,000lb pay load bolts rip out some how. They would never rip out, 
but better safe than sorry with any climbing wall right?
Upright Trusses on the back wall
I was antsy, so I slapped a few pieces of plywood up just for fun to climb it.
Editor’s Note: I think we all would do this!
Testing out the Wall
Climbing Wall with Plywood Attached
IMPORTANT! I made a climb on the wall when it was just painted black because I knew I had to t nut and drill 520 holes total and wanted to set a climb to feel it out. I was stoked! I just left it there for when I was to work on it next. – So I got back to it, un screwed the bolts all the way off to find that my hold was still stuck to my wall. I pretty much one arm pull up’d the hold to get it off. It ripped off a piece of plywood, and paint pretty bad. They all did this on  varying degrees of how bad it was. I knew there was something to be done.
Purchased a paint tcalled “Anti-Skid Deck Paint” , it already comes textured and for 8 extra dollars go the extra mile. Also purchased an paint additive called “Shark Grip”  to add that extra texture. I completely over did it with the Shark Grip additive mixed into my Anti Skid Paint and it was a great idea. It made for a super textured awesome wall. Let the deck paint dry for at least 48 – 72 hours. My wall is super textured now, I love it. 
Editors Note: Hold’s sticking to paint is common and can destroy your paint job. Marcus’s solution is a common one and looks great. Another option is to polyutherene the hell out of it, but this textured paint is a much better solution. I only suggest polyutherene on painted volumes like my Optimus.

    I hope someone skated that perfect love-seat before you built! Bad-ass wall either way Marcus!
