Build a Calisthenics Park With ZERO FASTENERS & ZERO TOOLS That’s Portable (1st Section Assembly Instructions)

This is the simplest and most sturdy bar system I could invent with the base component comprised of accurately milled Northern White Cedar timbers along with structural grade metal tubing that just about any able bodied person can assemble. Both timber and steel are produced here in the State of Maine, USA. Patent pending as of March 1, 2022.

2 Northern White Cedar (rough sawn) posts 5x5x8 (post dimensions are a true 5 inches by 5 inches by 8 feet) that have already been milled to specifications for this singular application.

2 carbon steel tubes with a minimum rating of 80 gauge at 6 feet in length for the legs. Diameter is designated 1 1/4” (actual diameter is 1.66”) which is the minimum requirement for this application.

1 Carbon steel tube of 5 and a half feet in length for the cross bar. The 1 1/4” (1.66”) diameter is depicted while doing a pull up, however, to apply the inversion boots a designated 1” (schedule 80) was used. This application system can accommodate three diameter sizes: 2” in (1.90”) for “fat-bar-style grip”, 1 1/4” (1.66”) for classical uses & 1” (1.315”) for a more traditional grip and smaller hands.

1 folding saw/construction horse, a stable step stool or anything equally suitable.

To layout your components in the order that they will go together, the pictures provided, in conjunction with all markings on top of the posts make this system quite simple.

This system goes together easily with these visuals and extremely brief explanations, as every single step is “Tab A - Slot B style”.

5 parts - 5 tabs - 5 slots…easypeasy.

Markings located only on the top of the post, (there are no markings on the bottom) will show the orientation and the post marked with a “L”. This configuration has one hole at the top for the cross bar. Slot B on top faces inward towards a person exercising.
Lean the post safely and fairly upright for support against your work horse or suitable step stool and proceed to the next step.

Insert one 6 foot structural steel tube into and through the left post and leave it to rest on the work horse or capable stool.

Proceed to join steps 2 & 3 for the right leg and set it two to three feet away from your supporting work horse or stool and lean it as so it will be ready to accept the cross bar when stood upright.

Add the cross bar by placing it in and through the right leg that is prepared to be up right. The cross bar should be on the ground and work in concert with the right leg for balance while resting upon the work horse after it has been installed.

A word of caution - This is the part where the able bodied person would need strength, coordination and balance. I would recommend two or more people engage in this assembly, however, one able person could perform this step, safely & easily.

While standing on the work horse or stool, reach down and lift upon both parts of the right post by grabbing as far down as possible for the best leverage. Once the cross bar is within reach of the left post, place it in and through.

Make it cinch!

Splay each assembled leg from the bottom OUTWARD. The wooden posts are engineered to accept the stress of the tube steel as it splayed to its fullest extension.

When splayed fully, the cross bar will be cinched and unable to rotate. The legs when cinched will have genuine stability, unable to wobble from left to right. Forward and backward movement is not possible due to the tubular steel legs inserted properly and the bottom of the post.

Caution: swinging in a stunt-like fashion would likely topple over without anchors. This particular configuration is intended for classical and strict disciplined movements. Kipping up will lead to tipping over.

This is the system of my invention and the reasoning within the patent of “no fasteners” is a strategic system of accuracy that requires correctly chosen hole sizes and respective locations, the appropriate angles, as well as, the thickness and length of the timber are all paramount to accept the tubular carbon steel to exert its structural strength, integrity and longevity for the safe long term usage.

It is as strong as any one could make…it possibly could be made entirely of metal or fiberglass or super polymer, however, I have direct access to sustainable forestry products of Maine. Northern White Cedar is amazingly durable and last a generation.

So I invite the world to embrace this idea and make them for yourself or add this to your business portfolio as a woodworker.

It’s a simple symphony of bore holes and angles of gold within the wood specimens as shown.

I invented this to provide the ultimate stability for my hyper-mobile shoulder to achieve scapular knowledge and strength and assemble it anywhere permissible. I have been able to practice stabilization of the shoulders on a stable device...my shoulders have had setbacks on rings and other portable parallettes. I am enjoying daily routines every where I can, safely and stably.

Stability has been achieved and I have eliminated harmful wobble in equipment that has impinged my shoulder time after time simply trying to stay in shape and regain and maintain general physical fitness. Portability on a large scale can accommodate events that require many pull up bars to create a park calisthenics that can be transported, assembled and used in mere moments.

Within each instructable I publish I will include only assembly instructions - should they be vague in any respect - please contact me directly. My website has timber and steel supplies for purchase and is the accepting authorized usage requests.

I am offering the general public, world wide access to the patent I have filed via licenses for all those that seek to manufacture one or more for themselves or for others honorably becoming an authorized user (or authorized dealer)
