As I have mentioned in some of the other posts, the casters mounted directly on the feet of the steel legs was not working very well.
The legs were meant to be attached to something.
Base for the Stand
I built the 37" x 25" wooden base shown here. The steel legs attach direcly to the base.
To remove the caster I used a hydraulic jack to raise the stand in order to detach the origninal castors.
I added a 3/4" Baltic birch skirt to the base in order to attach the new casters.
The new casters are used to raise the base so that it can be moved as needed.
To move the machine, the casters are placed in the down position as shown here.
Once in place, the casters are placed in the up position as shown here.
In addition to the base, the stand needs some bracing.
Before fabricating any steel bracing, I added some slotted angle to the ends and used chain and turnbuckls to cross brace the stand.
I did the same on the sides using the existing sloted angle.
How Does it Work?
I am very happy with the stand now, even if it looks like something from a Frankenstein movie. It is extremely rigid now. While I am pretty sure it can handle the acceleration of the machine, I probably wont use these legs in future builds.
I will replace the chain once I start working on my downdraft system.
