Hello,
The Excalibur saws were primarily designed for the North American market, so what Sean says is essentially true. Since the European standard is 30mm blade arbours, it is unlikely anyone can use the jig on a TS here. Steve, your saw is the exception that proves the rule. Although dado stacks are not in themselves illegal, the use of them in industry will in essence be illegal, since making partial thicknes cuts is pretty much outlawed. Technically, it might be possible to guard and provide anti kick back measures to use a dado, that will comply with the laws, but unlikely to be convenient enough to make the use of the dado worthwhile. Home woodworkers do not have such legislation to comply with, but in reality, the infra jig is a router table jig in this country. In fact, I bought one the other day, and it seems excellent, EXCEPT there was a manufacturing fault on mine, which I'm waiting to have rectified. It will work with standard 2 flute bits, spiral ones are not necessary, Just to answer your query on this issue above.
When I get the replacement, I will give a little review of the jig. I would say to the OP however, the guide will only run in a standard 3/4 in mitre slot, so no use for your router table, if this is not the case. It might be possible to make a replacement guide, since it simply bolts on. However, I think the jig would be less accurate for it ( the adjusters for removing the slop would be lost) and using it in a cheap router table would be like dressing for dinner at Macdonalds! Perhaps you should make a router table with the correct slots and more powerful motor first.
Mike.
