I am getting a handle on blogging (late is better than never, right?) so bare with me as I cut from the original, paste in new entries, and add more.
As I stated, I sought advice from everyone I could think of about measurements, metal dimensions, maybe even buying a well worn Simplicity cart to use. Chris727 shuttered in his shoes when I mentioned I was thinking of "destroying a Simplicity dump cart for the cause. That caused me to rethink and remember a project build I'd followed on SimpletrACtors by snohiker https://simpletractors.com/forums/topic/37363-carryall-update-5-26-11/#comment-413033 Take a look at it and you will no doubt see similarities.
Again, you will see the similarity. If that furrow has already been plowed, and its working, all I really need to do is fall in line.
The run-down garden cart I bought from a CL ad was perfect. 2 flat tires and looked terrible but the bed was in nice, shape.
In reality, I am not sure how much use this will get but I can pick it up and throw it in the corner or on a shelf to get it out of the way much easier than moving my Allis dump cart that is in too nice shape to use anyway. And, I just like tinkering in the shop, now in our basement) as it takes my mind off work and other stressful stuff. AND - If I remember correctly former Club Secretaries have had a carry-all or a version of one anyway. As it warms and I use it this spring I am sure there will be a modification or two in the works. gw
