Honestly I do think the tool is worth the money, for the time it takes to get built
I do not like that spindle system, while every other manufacture uses the typical nut and safety pin.
But If you’re handy, and would like to build your own tool, then you can build it for real cheap.
Just get the correct pipe diameter, put it over the special spindle nut, mark it with a sharpie, and grind off all the unnecessary metal off the pipe, saving only the teeth you need at the correct highth, drill a hole across the top through the pipe to stick a rod for the handle.
Or you can be lazy like me and just weld a rod across the top, and get it over with.
Anyhow, these are my 2 cents, if you are handy and good with tools
In my opinion this would be the cheapest alternative. Fast Freddy. ;)
