Ever notice the grooves in a road where the wheels of the vehicles travel most? Water likes to make a long lake in them when it rains so your tires hydroplane. You can see depressions in a parking lot where the vehicle tires rest. Wooden shelves can also show the effects of “long-term loading” by sagging over time.
I like to put wheels under all my stuff. I like to recycle. If I buy new wheels or castors I pay attention to the load capacity. If I recycle wheels, I guess at the load capacity. But load capacity is different than “long-term loading.” I would get flat spots on wheels, or have them fail totally, over time, when I used them to support my radial arm saw or big old cast iron table saw.
So, I worked to take the pressure off the wheels I used unless I was using them.
For now, I have decided to create a new form of bench leg that houses a wheel in a different way than I am used to seeing around shops. It requires using two legs on each corner to house a wheel and enable a short bolt/axle to be used to complete the mobilization of that corner of the bench. This may not really be a new idea, but it is new to me.
When the wheel is not in use, there is a “horseshoe,” I call it, placed under the leg and wheel to transfer the weight of the bench directly to the floor and take the stress off the wheel. The wheel can turn freely when the horseshoe is in place. The horseshoe consists of a piece of ¼ inch plywood rimmed on three sides by pieces of two by two. To use, the bench corner is lifted slightly and the horseshoe is nudged under the wheel with your foot. Of course the reverse would be true to remove the horseshoe.
I am completely open to other ideas as I realize this is only a first shot in my war against flat shop tires and castors.
Now I’ll shut up and let the pictures say the thousand words I am not able to utter.
