I am planning to make a new cabinet to put my old Delta lathe on & am thinking of building a torsion box base for it & filling the box with sand for ballast weight.
Does anyone know how to figure out much sand it would take to to weigh 400 lbs. & how deep that box would have to be if it was 17" x 48"?
I'll put this on heavy duty locking casters that will be mounted on 2x4" steel tubing that will stick out 6" to the front & back for the base for stability.
These measurements match closely what I have now accept there is no place for drawers now & I will have the motor underneath instead of on the left end like it is now.
As you see the set up I have now it is very very stable & weighs about 420 LBS. This is what I hope to have when finished but on wheels with drawers & the motor inside the case under the lathe so I can use the outboard turning capability of this lathe.
The first picture shows the whole lathe. The second picture shows one ot the feet the lathe sets on as well as my free standing tool rest.
Sometime in the future I hope to add a 3 phase motor & VFD.
Any thoughts an this are welcome too.
