I don't use the splinter guard to locate the rail either. Bad idea IMO.

A simple way to locate the rail to your intended cut line is to cut a spacer the width of your guide rail and use that as an offset to locate the back side of the rail instead. To use, place spacer's right end to the line and then but a stop block up to the spacer's left end. Clamp stop block(s) in place, remove spacer and place guide rail up against stop block(s). Simple.

Hi Corwin!

I disagree. To me its much simpler to align the splinter guard to the mark.

Of course that requires a splinter guard that is in good condition and that the blade/saw to be used is the one that trimmed the splinter guard. If that is not the case, a simple work-around is to put a Post-It note (or opaque tape) on the bottom of the splinter guard in the vicinity of the marks then trim the add-ons with the blade/saw to be used and align as usual.

Nice idea using Post-It notes, Michael.  [big grin]

What I like about my method is that when ripping sheet material you don't need to go back and forth to check either end to make sure it remains lines up. Using stop blocks on either end allows one to set the rail in place where you want it without any further adjustment.

I remember years ago people here being impressed with the razor blade method. I wasn't. Far to fiddly for me.

@Corwin I did use your method when I was making a complicated form that required symmetrically opposed compound miters to be pocket cut. There used to be a picture of it in a photo gallery here (in the old days, two computers ago so I can't find the original anymore).

Here is a nice trick in one of Brian Sedgely's pinterest videos.  This is the best way I have seen to join the tracks

Nothing beats a long rail, but this is pretty good.

I bought the 3000 several years ago and have never regretted it either, except that storage in my 16x16 shop is a hassle.  However recently I have been using it less and less.  I have found that for base and upper cabinets which is my main use of sheet goods, I can make the first cut across rather than lengthwise without increasing waste to any measurable degree.  I have some tall cabinets coming up that will be an exception but I have found crosscuts work fine for all else.

Since this hasn't been mentioned in the comments above, I'm curious what general experience is as it eliminates the need to join shorter rails if that is all you have.

Regardless of connected rails or a single looong rail I think it is important to remember to have the sheet goods supported well _all the way_ so it doesn't flex or sag when you are running the tracks saw along the (intended) cut line.  The rail itself is not support enough.

I use the Bosch FSN rail system for my Bosch, Metabo and Mafell gear and so far - zero problems. I did score a 3m (I think it is 3100mm) rail for less than a standard rail from a dealer that had an uncollected order. I didn't think I'd use it very often but it has been great to have both for breaking down sheet goods and for long cuts.  It hangs up on the ceiling in the workshop in the original cardboard sqube it came in - it is a bit of a hassle to haul it out and stick it in but well worth it.

Line up has been reduced with the introduction of Mafell/Metabo tools. Red Green and Blue do mix well in the shop.

To avoid lateral inconsistencies I place a support about half way when ripping sheet goods.

The extra time it takes to set things up is worth the effort, YMMV

Welcome to the FOG kevreh

It's a Walko IV sitting on some Stanley  saw horses. Perfect height for me.

Nice setup, thanks. Makes me think I need to improve my sawhorse game,  ;)

I was wondering about aligning guide rails myself today. I have the standard 1400mm guide rail and was looking at getting another 1400mm LR32 guide rail since I recently picked up an OF 1400.

I have read a lot of where guys were using levels to align. Well, I don't have a level, nor do I have any other use for one, so I was wondering: Is it possible to just run a crosscut along the 4' side of a sheet of ply and then use your fresh cut to align? Basically using it as you would a level?

That's a perfectly good plan. Cut a 3-4" strip at least and use the cut edge only. Factory edges aren't good.

You can also use the cams on your saw to do the job too. Video link further up.

I watched that video, but would question the accuracy of it. I have never actually joined guide rails before, so my doubt comes out of pure thinking and no real world experience.

If I used the base of my saw, my length of alignment is fairly short. Would that short length of reference be long enough over 2800mm of rail? But then again, that method is just slightly shorter than the Betterley straight-line connector.

I used a 72" piece of 8020 2012 extrusion I got from their EBay store (closed for holiday's...was going to check price) for years before buying the 118" rail.  Last piece I bought was $20 ish + shipping...I never bought just one piece, I've literally bought thousands of $ material from them over the years.
