The Spin Hopper obstacles were engineered and fabricated for Louis & Kellie Amaro of the Midwest Warrior Academy. They contacted Solvers Manufacturing to design and fabricate unique obstacles for their gym. As we dialogued about their needs a number of important constraints were highlighted:
Project Constraints
- Safe to use
- Unique to their business
- Well constructed
- Easy to secure to their gym truss system
- Easy to disassemble and transport
- All surfaces and edges should be smooth
- They should have a durable, bright red finish
Engineering
Louis provided links to pictures and YouTube videos to guide the design process. Solvers designed a 3D model, determined dimensions, and selected materials.
Estimation & Procurement
Estimation
With the Spin Hopper design finalized Solvers worked with suppliers to get quotes on materials. These quotes were used to finalize an estimate that was shared and accepted by Louis & Kellie Amaro.
Procurement
Supply chain constraints and escalating material costs were major factors in material selection. Material quality was also crucial. A few different types and dimensions of steel pipe and tube were selected during the design and engineering phase of the project. The 3-1/2" Schedule 40 pipe was sourced locally, but was freighted in from Texas where the oil and gas industry has extremely high standards for steel quality. Pillow blocks and 1" cold-rolled solid round bar were sourced from other suppliers.
Fabrication
As the materials arrived fabrication began. The following pictures show how the process for the Spin Hopper obstacles unfolded.
The 3-1/2" Schedule 40 pipe used for the spin hoppers needed to be perfectly smooth. To accomplish this the pipe was cut to length then machined to be perfectly concentric. The ends were chamfered to provide room for a heavy seam weld.
Top Dog Powder Coating did a brilliant job with the powder coating. They baked all the parts to degass them. Then they sandblasted all the surfaces for a uniform finish. They applied primer, color, and clear powder coat and baked the parts after each application. The results were outstanding!
The Spin Hoppers turned out beautifully. Louis and Kellie Amaro were delighted with the results!
