I put a new router top table together a couple of months ago. My old table was a Bosch 23 router in a Bosch bench table.
I used a Jessem lift in a Sawstop cast iron top with a Porter Cable 7518 router motor. I mounted the cast iron top on 2 inch angle iron with 1 ¾ inch square iron tube legs. I made the legs short (16 inches) so I could everything on a wood roll around cart with drawers and so on.
The whys of it:
I went with cast iron because I like the solid feel of it. I talked to a Wood craft salesman and he was pushing phenolic for the top but when I asked what he used, he said tried phenolic tops but they all sagged over time with a heavy router; (yes I know those are fighting words on this forum but that is what he said). He had made his own now but had to use 2 inches of reinforced plywood. He had been using it for about 2 years without issues yet.
My Bosch motor had to be un-clamped to make height adjustments. When it was new, I could count on it re-clamping to the same spot plus my change. As it aged though, it was all over the place. The Triton router from the literature on their web site say the Triton motor has to be unclamped to change height. I did not want to have to deal with the same issue with it that I had with the Bosch so I chose to buy a lift. Triton has a lot of people that like it on the forum so again I am opening myself up to a lot of slings and arrows on my feelings on Triton.
The cost of Triton versus the Porter Cable plus Jessem lift makes the Triton look really good. In my defense though, the Jessem lift is great. If I need to make a 0.010 change, I turn the dial to make the change, make my cut and I get a 0.010 change.
One last thing, I went from the 18x27 Bosch table to the 24x32 Sawstop table. If you have the room, choose a bigger table. The extra support for your work piece is a real plus.
There are craftsmen and there are artists and then there are guys whose wife says “That looks nice dear but it doesn’t match anything in the house.”
