Ok my last post on the subject. 350' cut 3 sheets of 3/4" d grade ripped straight to 3"×8' rips. snap a straight line accounting for the offset of the base of the jigsaw to the blade. securely fasten said strips to this line. saw rides with the base against this and cuts at the desired mark. Yes the 300 would be good for this job but I'd use it in a similar manner. though I still prefer the p1cc for this just to keep the plumes of dust lower and I doubt the job warrants importing the tool. I do stuff like this all the time. If anyone owns 350 linear feet of track maybe you could lend a few hundred feet to red. Hopscotching track also seems to be a bit of a time waster as well. You have gravity to your advantage just butting the saw to strips so you cant really go off your mark. The track really doesnt offer an advantage over a simple straight guide and some basic measuring. interested to see how red decides to go after 3 pages of discussion. I suppose it all proves that theres a million and one ways to skin a cat. Respect to all

No need to let any of this get under anyone's skin, fellas. I needed "some thoughts" from the Mafell crew and, quite frankly, there are a lot of good ones in this thread.
As I mentioned earlier in the thread, I've built frames on foundations that were "good enough" and -- now that we've invested a lot of hard-earned in accurate guide rails -- I think that it only makes sense to at least try to figure out a way to use them.
As Jack wisely alluded to, the guide rails, if chosen for the job, will be drilled in a friend's machine shop (which we've always had free access to). In my mind, that's the only way to ensure that the rails will still function as designed. I don't know if anyone else has experienced this, but the Mafell guide rails actually conform to imperfections. I just cut a sheet of distorted OSB earlier today, for example, and our KSS80/rail combination, as ever, made a nearly flawless cut. The ICFs that the OSB sheathing is attached to are not perfectly flat, so that translates into [somewhat] wavy cuts, which, considering what I just typed about using the guide rails on imperfect surfaces, is another pro for the use of guide rails.
In the end, we'll try a few different approaches and pick the one that makes the most sense, overall. Thanks once again for all the great suggestions.

... You, and many other, usually supply some good suggestions... So I sure we get our money's worth at some point (again). These threads give some interesting approaches that help to expand the way we look things, so we all probably get some value out of it. (I certainly did).

My only other suggesting is of no use this time, but for future times is their a way to possibly clamp the sheets at the correct level using your laser level and reciever. So they don't move when screwing the tel screws in causing the unlevelness. Then saving a lot of piss farting about

Sorry, I didn't mean to ruffle feathers here. I had a 30+ year career in R&D so my past experience in a group problem solving situation was for everyone to come up with any ideas, no matter how wild, then pare down based on what the projects leader stated were some of the limitations as we stalled, and then continue on. And that was my approach here. Red brought up some of those limitations as the thread progressed, ie the chalk line was not up to snuff, so to me that solution gets crossed off. In my company we all realized that we were on the hunt and there was no malice to anyone's ideas getting shot down, it was just part of the process and your own crash and burn was coming. I've stated before I can be a curmudgeon in that if your expecting a tactful nature it is not in my genes (you've never met my mother who had brought another teacher to tears explaining that she needed a new career) nor did my R&D experience do anything to smooth the trait over. My dismissal of the P1cc had nothing to do with its ability, as the video certainly shows its up to the task. My concern was with the time it would take to cut that footage, or meters for you metric folk. A small circular saw would reduce the time keeping a saw elevated and the fatigue. Red, I'm not sure if they make a screw in a good size like what I'm thinking. My first thought was a GRK cabinet screw with its large, low profile head located in the flat, thin center section as when I tested that with my rail and the MT55 the installed head had clearance. The other was GRKs structural fastener as both of these have a under head pilot that is thicker then the threads, since most rolled screws have the threads wider then the screw shaft. However the larger structural screws I have in stock when installed have a head surface that is too high, which could be ground lower although the torx engagement would be compromised. The rail could have a chamfered hole for a flathead screw, but with the thin section of the rail I'm just worried about pull through. I've used the GRK structural screws when installing a steel underplate to joists with a precise hole in the steel so there would not be any slack during the bending moment. They work well. in the end, whatever works and is feasible to the OP. As he stated, there are good ideas abound. Attachments:![](//storage.proboards.com/3639287/thumbnailer/iQIVKPNIy82tjImDcC2t.jpg)

Holmz If I only had a jigsaw that's what I would use but I would bet my house red has plenty of saws. Any way whatever way you go with it lets know

Holmz If I only had a jigsaw that's what I would use but I would bet my house red has plenty of saws. Any way whatever way you go with it lets know I hope I didn't give the wrong impression. Mick is right, we do have other saws to choose from, but, once again, I was inquiring about the various [possible] uses of Mafell's guided saws from the folks who know best...In my mind, using the saw/guide combination is still a new and enlightening discovery.

Track guidance is great, you can cut as if you're running a whole deck through a table saw

The p1cc can surely do 6' /minute which means the the 100m would be under an hour. Either way, one may end up needing a can of spinach before or after.

That be true. Plus some magnesium and potassium to keep away the cramps.
