Like you said the pictures don’t work, I posted mine on my profile. Double shop 50 x 128x 23.5 with insulated foam filled panel walls. It is already too small, but I can live with it.
As mentioned above, supplyhouse.com is where I buy mine. You can get low or even free shipping depending on how much you buy or if you are setup as a contractor. I bought several thousand feet of pipe and hundreds of fittings for my house and shop project. Posted pictures here.
When I was in the underground business I used a balloon tied to a string, it is size adjustable and they really fly through the conduit.
Checkout all the conduits I had to do in my auto shop photos.
The spindle is 2" the motor is 20 hp 3ph, the wheels are 3 x 30 the hole in the wheel is 10".
Weight is around 5200. It really does the job and doesn't lug down.
Mine has a 2000 square foot mezzanine that could be used for living quarters although I don't but you could check it out as it has. Nice looking exterior for a steel building.
