I think Travis Wuertz's TW-90 is as good a grinder as you can buy. It is more expensive but it is a quality machine and very versatile. Here is a link to his sight: https://traviswuertz.com/

I have been using a 20' extension cord I made with 10 gage copper with the black rubber insulation for years for my belt grinder and 2 hp table saw. I have a 20 foot extension cord I use for my 50 amp welder. It is made of 6 gage copper wire. I would ask an electrician what wire size you would need for 75 feet, but if you don't mind spending the money, it should work fine.

If I decide to look at I'll test it. Thanks Zeb

Thanks Allen. Here is a photo of the teeth. They look ground into the blade.

Someone is selling this roughly 42" diameter saw blade that is about 1/4" thick. Any ideas what it would be made of? Is the whole blade likely high carbon steel or just the teeth.

I am not good at freehand sharpening. I got a wicked edge sharpener. It is easy to use and works great. Below is a link to their sight and a link to their forum. https://wickededgeusa.com/ https://knife.wickededgeusa.com/

Thanks Jeremy!

I made a stand with a hoist. It makes repositioning the block a lot easier.

Thanks Alan!
