jtooley75 Posted October 20, 2011 Report Share Posted October 20, 2011 Can someone explain to me why a cabinet mounted trunnion is better than a tabletop mounted trunnion? I hear that it is more accurate, but why? Quote Link to comment Share on other sites More sharing options...
Sac Posted October 20, 2011 Report Share Posted October 20, 2011 The cabinet mounted trunnions that you find in a heavier duty TS are better for a couple of reasons. One, they are usually heavier, which helps the saw keep vibration down. They are also easier to adjust. They stay mounted to the cabinet, and you move the table around the trunnions. Well, in theory it is easier. I think SawStop has the best system for adjusting the table and trunnion. Mine took me a long time to do. But those are just a couple of reasons. Someone might have more. Quote Link to comment Share on other sites More sharing options...
jtooley75 Posted October 20, 2011 Author Report Share Posted October 20, 2011 Ok, because I am ready to buy a new table saw and have a budget. I wasn't sure if spending a couple hundred more for one with a cabinet mounted trunnion was definietly worth it or personal opinion. Quote Link to comment Share on other sites More sharing options...
Sac Posted October 20, 2011 Report Share Posted October 20, 2011 Oh, I think that definitely falls into the "worth it" category. What is your budget and which saws are you looking at? Quote Link to comment Share on other sites More sharing options...
jtooley75 Posted October 20, 2011 Author Report Share Posted October 20, 2011 Well, for a while now I've been looking at the Ridgid R4512, but am leaning towards the Steel City 35590c due to it have cast iron wings and the cabinet mounted trunnion. The lifetime service agreement on parts with Ridgid is nice though. Quote Link to comment Share on other sites More sharing options...
knotscott Posted October 20, 2011 Report Share Posted October 20, 2011 In addition to being considerably more robust (in most cases), cabinet mounted trunnions are easier to align, often resulting in closer alignment. Here's a look under the hood of a Grizzly G1023SL, G0690, ...fairly typical industrial cabinet saw design, and even a glimpse of the cabinet mounted trunnions used on hybrids like the former Ridgid R4511, and current Craftsman 22116: Here's a look at the guts of the former G0478 hybrid, Delta contractor saw, and Ridgid TS3650, also fairly typical designs for table mounted trunnions: Quote Link to comment Share on other sites More sharing options...
Dave's Not Here Posted October 20, 2011 Report Share Posted October 20, 2011 The lifetime agreement from Ridgid is attractive and I have some tools that are in that program. On the other, I wouldn't make it a deal breaker where a table saw is concerned. About the only wear and tear item that would really come into play down the road would be the belts or motor. Unless you have a really friendly service center that might bend the rules for you, hauling your entire saw into the service center to get a replacement belt just isn't worth it as under the terms of the service agreement you must bring the tool into the service center for any work.

jtooley75 Posted October 21, 2011 Author Report Share Posted October 21, 2011 Thanks for the pics knottscott. That gives me a good visual in what they each really look like. I appreciate it. And yes, Dave, you are probably right about the TS parts. I think I will spend the extra cash and get the SC. Quote Link to comment Share on other sites More sharing options...
Joraft Posted October 21, 2011 Report Share Posted October 21, 2011 I know Felder is not in the running here, but just as a point of interest here's a photo of the trunnion assembly on a KF700: Quote Link to comment Share on other sites More sharing options...
Sac Posted October 21, 2011 Report Share Posted October 21, 2011 Is it me or does it look like the scoring blade is on backwards in that photo? Quote Link to comment Share on other sites More sharing options...
Joraft Posted October 21, 2011 Report Share Posted October 21, 2011 Is it me or does it look like the scoring blade is on backwards in that photo? No, it's on right, scoring blades are usually set up for a climb cut. Quote Link to comment Share on other sites More sharing options...
