Theory Good, Compatibility Main Issue
I had high hopes for this product, but this product is incompatible with my Skil saw and incompatible with the one Kreg recommended (Makita). Notice that the description states that it works with "most" circular saws. My problem arose when I tried to mount the saw to the slider. The two swing arms, mounted with pointed bolts at their end mechanically interfere with Skil's levers and the worm drive. Thus, it is impossible to move the saw laterally across the sled. Furthermore, when I got it finally mounted with the front end of the saw squared with the front of the sled, and followed directions, the saw cut off the entire rubber extension protruding from the sides of the track. Tech support, very helpful indeed, told me not to be concerned since their purpose is only to minimize splintering. On page 3 of the manual, it tells you to cut off 1/32th of the rubber strip, which is impossible to do.
So I went through the ordeal of returning the saw to the 3rd party that sells this saw on their web site. It took several messages to point out that the product was "defective and inoperable" (the category selected on advice from Kreg tech support).
But I really wanted this product to work, so I cancelled the return and told them I was going to take the sled to the local HD store to ensure I could mount the new saw Ryobi with freedom to move the saw laterally.
So I took this saw home and mounted it without any interference from Skil like parts experienced before. HOWEVER, another incompatibility was discovered. While the openings on the slider are about 1.125" (ample room for the spring loaded guard to swing through). This space is decreased by about 0.5" when one mounts the sled on the tracks groves. As such, there is not enough room for the spring loaded guard to swing through! ARRRG!
So I'm returning the Kreg unit again. This time I will use an 8' level, clamped at both ends. Using hardwood like purple heart won't work as humidity changes.
In case that the third party to Amazon refuses to accept my return, Amazon will cover the expense. My advice to Kreg is to list the names, models, and year of saws that will work for the benefit of their customers.
I rate the product, documentation, and product description as 1 star, but I rate their Tech Support as a 5.
