TSO flip stop moves

[bobtskutter]

Hello all,
I've been using the TSO rail square and guide rails for a while.  I set the system up to batch out panels, but I've noticed the flip stop moves along the rail very slightly every time I but the flip stop up against the plywood sheet.  This has caused me to end with some pieces being a few millimeters bigger than they should be.
I've tested the theory by setting the flip stop on the rail and tapping it gently with a block of wood, it moves.  I guess this is a result of the components being very smooth aluminium.
Has anyone else noticed this behaviour?  I tighten the flip stop holding screw by hand and I can't "push" the flip stop along the rail, it must be tapped with a block of wood to move it.

Many thanks
bob

your experience suggests that you can expect to benefit from upgrading to FlipStop v2.0.
To support customers who have earlier version FlipStops, we created a
        Reversible FlipStop v2.0 Upgrade Kit Upgrade Kit SKU  61-392 A; $ 19.95 ea.

You will really appreciate all the enhancements in use, not just the absolutely positive lockdown of the Calibration Rod.

Hello TSO Products, thank you for reaching out to me.
I should have been more specific in my original post, sorry.
I am using the Flip stop V2 (bought from Axminster, UK about 6months ago as part of the full TPG kit).
The whole flipstop moves, not the calibration rod.

It's probably the way I'm using the system, I'm cutting 18mm boards of OSB3 to make cabinets.  I'm using the 2404 festool guide rail and I have a small workshop.  When I position the board and move the rail, the flip stop tends to "tap" into the edge of the board.  I'm not using a hammer, or excessive force, the rail tends to jump across the uneven surface of the OSB sheet.  I'm trying to get into the habit of lifting and sliding the rail gently, but it suprised me that a gentle tap can move the whole flip stop.

Regards
Bob

thank you for explaining the cause of  FlipStop movement you reported earlier.
The force of "impact loading" becomes clear when you see that the FlipStop cannot be moved by hand alone once tightened to the maximum possible by hand.

Your unusual case  validates TSO's through-bolted connections design for  all our non-adjustable TPG System elements which attach to guide rails. During the research leading to TSO's Parallel Guide, we became aware of the problems with other (non-FESTOOL) parallel guides whose track assemblies and guide rail attachments have slipped slightly in customer use only to be noticed too late when the parts no longer meet the set length.
To enable the FlipStop be infinitely repositioned, requires an adjustable "clamping" method. We upped the game by replacing the commonly used hardware store Hex-bolt and Nut with a large area Nutplate with machined ends for easy lead-in aided by a StarKnob  to provide greater user hand clamping force .

In your extreme case you could experiment at your own risk -  not covered by our warranty - replacing the FlipStop's M6 Stud StarKnobs with suitable length HexBolts you can tighten to a greater Torque using a Spanner. Just stop short of damaging T-track extrusion or the Machined M6 Nutplate.

Hope this helps!
Hans

Considering how much the TPG kit cost (here in the UK) i don't think I'll start modifying it!  [laughing]
I think I just need to be more careful when moving the rail.

IS there a way to double up the stop like when we use a jam nut on a bolt that needs it? Maybe two flips tops or a plain stop to slide in behind it to help hold it in place?
