Step 3: Drill holes and assemble

I think the easiest way to drill the holes is to line up your lumber and clamp it together, then drill through multiple 2x4s at one time. Even if your measurements aren't perfect or the holes are askew, at least the bolt will fit through smoothly, which is what's important. I discovered this technique halfway through construction, so some of my beams did not line up perfectly.

When you're finished drilling, keep the clamps in place and insert the bolts. Be sure to use washers on both ends of the bolt. I used a mallet to pound the bolts in, which helped speed up the process.

If you need to take the bolts out, don't make my mistake of hammering them out from the threaded end - I ended up ruining several bolts by hammering the threads away, making it impossible to screw the nut on.

View the photos to see where I drilled the holes.
<p>Has anyone else made this? I've been looking for a way to be able to set up a slackline in the house during the summer when our temps reach 115. I'm just curious if there are any other tips or things I should be concerned about with building it indoors. </p>
Love it thanks
Great idea! <br>Although I would be concerned about being injured on the beam or on the beam's protruding screws...
Yes, the bolts are a bit of a hazard, especially because some of the bolts I selected are an inch too long (7&quot; instead of 6&quot;). This isn't a good setup to learn slacklining, but it's wonderful for people like me who enjoy slacklining but don't have any other way to set it up.
Ha. How did I miss this when you published it? Doesn't beat two trees, but if you don't have two trees, this is great! Didn't know you slacklined lance, love the slow-mo shots! <br> <br>J
Thanks! Glad you liked the slowmo shot - I thought it may have been a little too 'show-off-ish.' I'd rather have two trees also, but alas my yard lacks that. And besides, this way I get to play with power tools and enter the wood contest :)
I think I might adapt this for an indoor hammock stand!
