Lifting a 900lb mill without a hoist
In article , Steven says...
I'd next build some cribing (or make a frame) to support the mill at
each end of the table, keeping the cribing as close to the knee as
possible.
Bad idea. The elevating nut will not support the entire weight
of the machine, it *will* strip out. The knee lock can not
be relied on.
Next add cribing or other support frame to the rear of the ram, which
I'd extend backwards to give you good three point support.
No ram on this.
