Stolmen bike stand mod for carpet flooring

This smart idea from Andrew lets you build the Stolmen bike stand on carpet flooring. Sturdy enough to hold two bikes in mid air.

"This Ikea-hack is mainly an extension of a design already featured, that adapts said design to more applications. The Stolmen Bike Stand seemed like such a great idea, I wanted to make a similar one for my apartment. The basic design is the same, with one significant change: an adapter to use the Stolmen post on carpet.





Normally, the Stolmen posts are only good for wood floors, as the post is held by compression between the floor and ceiling. Using the standard base on carpet, the carpet compresses over time causing the pole to become loose and eventually fall (a well documented issue). The version I made eliminates this problem by replacing the bottom connection with a different design.

Items used:
 - 4" diameter, 1" thick aluminum round (from Alro metals supply store)
 - "Speaker Cabinet 3/8" Toe Spike Set" from PartsExpress (p/n 240-725)

Instructions:
1. Drill a 1/2 inch diameter hole, 1/2" deep, into the center of one side of the aluminum round.
2. On the other side of the aluminum round, drill and tap four holes for 1/4-20 thread pattern
3. Install speaker spikes in threaded holes.
4. Use base instead of standard Stolmen base, placing the extendable metal nob from the post into the 1/2" diameter hole.

This design works because, as you tighten the post (using standard Ikea assembly methods), the speaker spikes drive through the carpet base and into the wood subfloor. This gives them a solid, non-giving, surface and allows the pole to be tightened properly and not fall over."
