For a difference of $130 between 510 and 520 then the 520 is a must!terrydowning wrote:Serial Number 271804 is in fact a 1954.
You have 3 table saw upgrade options from the mother ship.
555985 Mark V Model 500 to Model 520 Upgrade ... $1,321.68
555142 Mark V Model 500 to Model 510 Upgrade ... $1,196.89
505875 Model 500 Clear Saw Guard System Upgrade ... $227.83 I have this one, and I'm not happy with it at all. You still have the small table issues/problems (It seems I always need to cut things where the fence just doesn't sit right). Aligning the splitter located at the end of the table is troublesome and has burned many a piece of wood when it creates a jam. This also makes me feel less than safe. The dust collection is not very good and I have to sweep up anyway. Drilling and tapping of table components is required to install. The bolt that holds the upper guard in place has bent numerous times. All in all it's just a hassle and it does not add much to safety. For not much more money you may be able to score the required components for a used 510 upgrade. If purchasing new and you have the dough, go for the 500 to 520 upgrade.
