Question re TS75 exit and entry into guiderails

New to FOG.  I just got the TS75 -- deciding to buy after being blown away by the Carvex -- and as I was test-driving it, noticed that when the saw is entering the guiderail, there's a slight bump/snag in the sliding action between the base of the saw and the rail when the back is still sticking out approximately 2 1/4" in.  This is after the rear guide jaw has already made it's entry into the rail.  Same issue at the front, where the snag happens when the saw has exited 1 7/8 in. from the front of the guide rail.  Since it happens on both front and rear, I suppose it's intentional, no?  It's just a bit annoying since I thought the green guide jaws were supposed to serve as the entry and exit reference points, and there's no way short of making a mark on the saw base to know at what point I will hit the bump/snag.  Thanks for any responses.
 
All the TS saws have two adjustment knobs to take care of any play when on the rail.  The saws are designed to be used with both of the engagement "gibs" on the rail.  Otherwise you can twist the saw and have the "gibs" out of line, get a bump, and have a less than desirable cut.

Is this what you are experiencing?

Thanks for the reply.

It's not the back and forth slop, which was the first thing I adjusted for, rather, when I'm sliding the saw forward on the guide rail at the point where my saw has entered the rail almost all the way, and only 2 1/4 in. is hanging out the back, there is a bump/snag (vertical movement rather than horizontal).  It's nothing dramatic, but it's noticeable enough.  It wouldn't really affect the first part of the cut, as the necessity of plunging the saw before I begin the cut means that the whole saw will be in the rail by the time the blade reaches the workpiece.  But at the end of the cut (where the bump/snag occurs after the saw is 1 7/8 in. clear of the rail) it might cause an issue, for example if my rail is not that much longer than the workpiece.  The ultimate solution obviously is always to have enough rail to spare at the front and back ends, but I can imagine situations -- say when I'm cutting a very long board -- where I might have to cut it close.

I'm mostly interested in simply getting confirmation as to whether this is just the way the saw was engineered.
 
Hi,

  Welcome to the forum!  [smile]   

  I know the "bump"  / movement you are talking about. I guess you could say that is the way the saw was engineered, but you should really be using a rail that is long enough to avoid running the saw off the end at all. Especially avoid going beyond the gib that keeps it on the track ridge. It is nice to try to maximize the rail length but a longer rail is a better way to go. The TS75 needs a bit more rail length than the TS55.

First, [welcome] to the FOG!

Second, Seth is correct - no surprise there! You should be using a guide rail that allows your saw to stay FULLY on the rail at both the beginning and the end of the cut. That's why the And wile your TS75 will cut  75mm deal versus 55MM for the TS55, it's no coincidence that the TS75 comes standard with the 75 inch rail versus the 55 inch that comes with the TS55.

 
Thanks Seth and wow for the confirmation.  Adequate guide rail length is the key then.  The TS75 is a real beast on bevel cuts, but I saw elsewhere in the forum the suggestion to use the parallel guide as a kind of outrigger to stabilize the saw in the rail, which would beat having my hand on the base so close to the blade when I'm making 45 angle cuts.

Glad you figured that out from my cobbled post. Not exactly sure what manner of beast crawled up and puked on my keyboard while I was typing that....?
