Delta studied the whole field of band saw work and after hundreds of band saw users had been consulted to determine the most useful capacity for a medium sized machine, they settled on the 14" x 6" size, meaning that the maximum width of cut between the band saw frame and the blade was 14" and the maximum height of the cut between the table top and the upper blade guide was 6". In the comparatively few cases where the "swing" of the work required a larger throat capacity, it was found that a band saw of 20" to 24" swing was required, and the the addition of one or two inches to the throat was of no practical value. So Delta decided upon a standard machine that cuts up to 6" thick and they offer an attachment that will increase the capacity to 12". It included the open steel stand as shown. Model No. Delta patented a design for the band saw that included the slot for entering the blade to run to the side of the table.
