The ST-1500 can be mounted to the HW110S-52(P) in several configurations. One option is to drill and tap holes into the cast iron left wing and mount the ST-1500 directly to the wing. This may be more convenient for some people rather than moving the rails down or cutting them where the main table and cast iron left wing are connected to allow the ST-1500 sliding table to travel back and forth without hitting the rails. 


Depending on how the ST-1500 is mounted to the HW110S-52(P), the overall length can vary. 


If mounting directly to the main table, and removing only the cast iron left wing for the table saw, the overall length is approx. 95-3/4". 


If mounting directly to the main table and do not wish to use the ST-1500 Extension Wing, this would reduce the overall length by 9" for a total overall length of 86-3/4". 


If you do not wish to cut the front rail, it can be positioned further down out of the way of the slider which would add to the overall length to still bolt to the main table or you can simply drill and tap holes into the cast iron left wing and mount the ST-1500 to the cast iron left wing if you would benefit from having more table area. This would add an additional 7-1/4" to the above measurements or 103" and 94" respectively.
