Introducing a fierce man who created a self-propelled roller skate with a chainsaw engine

Roller skates are items that can glide on the ground with wheels attached to the sole, but you need to move your feet to move.

The engineering YouTube channel Fireball Tool has released a movie that creates a 'roller skating that runs on its own engine' that solves such complications.

In modern times, roller skates are thought of as shoes with small wheels on the bottom, but in the past, roller skates were mainly of the type in which large wheels were fixed to the side of the shoes.

This type of roller skates makes it difficult to balance, but the size of the wheels makes it suitable for moving on rough terrain, and you can see how it is moving outdoors by watching the video at that time.

'If big wheels are good, the bigger they are, the better?' So engineering YouTuber Jason Marberger started the development of roller skates using wheelchair wheels.

The target roller skates have a structure in which the shoe part is fixed to the wheelchair wheel shaft as shown below.

The shoe part is the binding that secures the snowboard and boots. The bindings for snowboards were chosen because they can be easily attached to work boots.

The rest of the parts needed to complete the roller skates are the parts that connect the bindings and the wheels. Since the hub part of the wheel handled this time was made of titanium and it was a material that was difficult to weld, Mr. Marberger decided to make his own iron hub and replace it.

The parts designed by CAD design software

SOLIDWORKS were cut out with a water cutter to create the parts to be attached to the binding.

In this state, the wheels tilt significantly toward the foot due to the balance, so 'fixed parts for the shin' are required to prevent the balance from being lost. That's why I will use the ankle protection parts pulled out from the binding to rely on the shin.

Connect the pipes in the same way as before ...

Completed by attaching the product of Tandy Leather, a major American leather product, as a belt.

The state of actually equipping it is as follows.

I tried to run with a long rod as a support, but it seemed difficult to balance.

'It was a great first exam, I knew a lot of what I needed,' Marberger said. When I actually equipped it, I found it difficult to stabilize the front and back, so I decided to create training wheels.

In addition, the fixed parts for the shin were also changed to a specification that can move back and forth because the shaking was directly transmitted to the foot.

In this way, the original purpose of 'roller skating using wheelchair wheels' was completed, but Mr. Marberger suddenly said, 'I want to add only one modification here that can surely break the ankle.' comment.

The modification is to attach an 'engine' to this roller skates.

So, Mr. Marberger procured the engine by removing the blade from the STIHL chainsaw 'MS 280'.

The rotation generated by the chainsaw engine is transmitted to the tire on the left foot side.

That's why I put on this magically modified version of the roller skates ...

Refuel.

You can watch the brave figure of Mr. Marberger running on roller skates with the driving sound peculiar to the chainsaw, 'Won, Woo On!' From around 15 minutes 39 seconds of the movie. Click the embed below to start the movie from 15 minutes 39 seconds.
