I hole sawed and drilled the other 4" square tubing today, then spent some time cleaning the garage. It was too cluttered for what I'm trying to do. Next I'll be hole sawing/drilling the plates that bolt to the same spindle, got them cut already.

Got these plates done.

Also cut the four pieces that will extend down from these, they're cut at a 15 degree angle to kick the wheels back some.

Got some more metal today. I got 2-1/2" square tubing with 1/4" wall, to rise up to make the A. They used 2", don't know what wall thickness. Two of the cranes at the wrecking yard were bent. Don't know what they did to bend them, but still wanted to go a little heavier. At first I asked for 2" square tubing with 3/8" wall, they only have up to 1/4" wall in that small of tubing.

I went to the scrap yard first, they had 1/4" wall round tubing that could be used to extend out the spindles the wheels bolt to. About .04" would have to be bored out of the inside. I know people with lathes, that's not a problem. Not sure 1/4" wall is heavy enough though, it will be right at 1/4" after boring. The yard with the new steel didn't have any remnants that size, and I don't want to buy 10 feet to get 14".

Those cranes at capacity see 1000 lbs, plus probably 600 more for the hoist weight. That means each corner sees 400lbs. Totally within the strength of 1/4" wall tubing. Weld a gusset up to it for extra strength.

The trolley showed up too big for the I beam. It has 4" diameter wheels, the I beam is 4-1/4" tall. I will see if I can find a taller I beam before trying to return the trolley. Got more cut today too, but no pictures yet.

I really like my saw. It does all the work, and I just keep an eye on it. I can't run coolant on long pieces because it will just run all the way down the end and drip off the end, but I run it when I can.

Got some progress done, my sons helped.

Already have horizontal supports a little below the I beam too, no pictures.

I'm not a welder by trade. I'm a machinist, but I think it should hold.

I made something similar at an old job for rebuilding massive gearboxes. I made it to where i could take it apart for storage or transport. Just made a base everywhere a met another tube than drilled a 1/2 hole through everything once assembled. It was nice because two weeks later we moved lol

It can be moved, just not as easy. We took it into the backyard with a garden wagon and a floor jack, with it laying on its side.

I took the 4 pieces of tubing to a friend to bore clearance for the hubs, just a while ago.

Snapped a couple more.

This shows how it's tied in, still a little more welding to do. I wanted to tie in to the vertical part of the I beam, but it wasn't really in the cards.
Image

Started welding on this before I put the A frame together.

Cleaned off the slag so I could see how the welds turned out.

I usually have someone else do my welding, but coordinating that has got more difficult.

Welds look fine, I doubt they're going anywhere.

I'm so spoiled using gas now, cleaning slag makes me a sad panda.
