I found out why the coping rail on my Infinity router table was jutting up and marring my work! I finally got the rail to come loose and found that the screws Infinity supplied to secure the table to the stand had penetrated the dado slot from below by about 1/32" or more. They pushed the rail up and I never noticed it until marks showed up on door panels I was routing. [...]
I cannot emphasize my disappointment with Infinity more. They just simply ignored me after I sent them pictures of the defect. I spent $1,000+ on that table and other items I bought from Infinity, and they have this ridiculously short and STRICT return policy. They even sent me the wrong jointer knives for my older Jet model, and they begrudgingly "allowed" me to return them for the right ones. I had a project going, so I hadn't tried to replace the knives until it was done, and that put me beyond their short return policy. Their own web page recommended the knives they sent! But my Jet model uses the thinner blades than 5/8".
Anyway, if they treated a good customer like me this way, how do you think they're going to treat you?? Buyer beware is all I can tell you. Carl F. Worden
I had a similar "screw too long" problem with Infinity Tools, but forgot about it until I saw your post.
The zero clearance insert (ZCI) I mentioned above has screw holes in the end for when you use it with a "split end" inner insert for 10 inch blades. The split accommodates a riving knife or splitter. You can use small wood screws from underneath to hold the two ends of that inner insert apart and prevent them from pinching together.
The screws that Infinity Tools supplied with their ZCI were too long. The first screw I tried punched through the top of the inner insert and would have scratched the wood being cut. It also ruined that inner insert.
Infinity Tools charges $14 for four inner inserts. I ordered an extra pack of the inner inserts when I bought the ZCI. Their manufacturing tolerances and QA suck, too. Several of them were too wide, and I had to sand them by hand to make them fit.
You could say that both of us were "screwed" by Infinity Tools. :-)
P.S. Despite all the issues, I still recommend that ZCI. It has saved me a lot of money from buying official SawStop inserts at $50 each. Unfortunately, the only source is Infinity Tools.
