Update 9/22/2021 - Added a longer Arm2 for those with shorter sanding plates, and widened the opening for the foot of the Tire Razor to go into the base. I'd been wanting to make a machine to move the sanding plate of my Tire Razor for a while, but procrastinated long enough for Kev (OXO_cube)...
I'd been wanting to make a machine to move the sanding plate of my Tire Razor for a while, but procrastinated long enough for Kev (OXO_cube) to design and share one for his machine. He has a similar machine, but it's not a Tire Razor, so I had to make some modifications. I ended up making a lot more changes than planned, and every part was more or less changed from the original.
You can download everything for free from the link at the top of the post. The parts are not hard to find, and are specified on that same page. However, if you'd like me to do all the work, or are unable to print your own, please feel free to PM me. I'm selling completed units (TIRE RAZOR NOT INCLUDED) for $40 USD, which includes shipping within the USA. International shipping is available at additional cost. Other color options are available. For example, I have recently shipped these two units.
Thanks to Kev for sharing his original design!
