you only ever need a tape on machine cut sheets

I actually built a rough version of one of these home-made squares on site last year out of MR-MDF and some aluminium strip - to replace a Festool FS-KS which on multiple cuts is a PIA as it forever flexes and it isn't long enough to be accurate. The ally bar one mine was too soft (and a tad small) so I struggled a bit with it as the slightest knock or bump and it would go slightly out of square (nd MDF dents rather too readily for durability). So I concluded that I needed to make one out of metal and use some form of clamp. Then I found the TSO version and by further digging all the other options I listed above. It became apparent that reinventing the wheel in CNC-machined billet aluminium was going to cost a lot more than simply buying-in. Hence my interest

I don't agree with you that you "only ever need a tape on machine cut sheets" because every so often you get a batch which is lozenge shaped with one or sometimes both ends cut out of square. So I always like to cut from my own square if at all possible. Your way of doing it involves measuring, marking, setting the rail down on the line, adjusting to your line and then you can cut - providing you or someone else hasn't bumped the guide rail in the meantime. With the guide it's measure, mark, drop the rail onto the work, align to the tick and cut. 15 to 30 seconds saving per cut and a guaranteed consistent cutting angle. Not a lot, but if you are installing window boards by the dozen, or cutting repetitive shelves by the dozen, or doing any number of repetitive tasks it soon adds up to both a time saving and an accuracy premium. My MDF version certainly did confirm this.

..... for years I just used speed clamps and a piece of straight board to guide my circular saw and my router. It was laborious and required careful measurements to ensure accuracy.

The tedious nature of measure clamp, adjust, fiddle, cut, unclamp, clean-off and then repeat was brought home to me last week when I did a little job which would "only require my cordless kit". So that's all I took. It morphed into a full blown plywood cutting session where I drained all five of the 5 amp batteries I had with me using the cordless circular saw to rip down 18mm F/E hardwood ply using a made-up straight edge and a pair of Solo clamps. I reckon that fiddling around with that cost me at least an extra hour in the course of the day - so my "Job and Knock" turned into a full day's graft (on shop fit hours)

in general i never use more than pehaps 1/3-1/2 a sheet for a single component most are less as most off the things i make are furniture or storage based and need to be off a size i can handle solo up to final assembly :lol:
touch wood have never noticed a duff sheet but off course maybe i have but assume the cabinet 'drawer'unit or whatever was at fault and just "tickled" it in :lol:

great thing about a track is

non off this measurement add 4" mark lay clamp cut unclamp :lol:


I think there's a place for both - If you need to split a plank lengthways a rail clamp is going to win over a track for me every time...

I am probably missing some tricks of the trade with a track saw though aside from the clamps. Grit tape?

i dont use or have the clamps you dont need them
on the odd bit off worktop i just use solo clamps and move as required
you have the weight off the machine plus its spring loaded so around 4kg dead weight plus another say 4kg against the spring so a 8kg push on the track it doesnt move because off the grippy strips

i always mark the tape and board then you automatically get an accurate transfer especially iff you are cutting several identical bits
i will check a part cut board after a few cuts to check for creeping error iff a very accurate cut is required but 99% off the time its within 2mm across the 1220



In my case it's when I am working with offcuts or part sheets, I choose the best edge and use the speed square to set the track so I now have a perfect 90deg corner to work from for the rest of my cuts, from then on it's only a tape as you say.

yes what ever works for you is the best choice :huray:
on the odd occasion i have an unsquare edge i prefer to use the roofing square first to mark a strait line yes i realize transfering a 18" pencil line over a board 3 times longer is open to greater chance off error but in general have a good eye :lol:

This is the one made by the joiner on the dewalt/festool pages. He’s made a few hundred so far and also a 22.5 degree one.

Ever heard of a chalk line? Always straight when under tension - always straighter than by eye

yes off course :lol:
its more to do with lining the saw track up with a short pencil line and getting it accurate at the unmarked end :thumbright:

Oh, really? Found the vid below. Have a look at this (below, circa 0:56 to 1:20) and then tell me that with a straight face :wink: I'm thinking of tasks like making window boards from scratch (which I have had to do more often that I would like on site) or ripping up a full sheet to do back of house shelving (or for that matter making up bookshelves at home), etc - tasks where you need to do loads of parallel rips then loads of crosscuts which are wider than any chop saw with nary a table saw in sight.

it is only ever to square off random angles on mdf or ply :lol:
trust me i have all sorts off jigs and tools and if it would make life quicker or easierv i would invest in one :lol:
as 95% off my work is workshop based i have in general around 3 tool choices to finish any task :lol:

Just a little update. Had the Palette 370 on test for a few days now. It actually works pretty well - far faster and more accurate than two pencil marks and align the rail. Far better.

But then I'm currently putting down around 500 sheets of 8 x 4ft 3/4in hardwood plywood with lots of crosscuts, so I really needed this, Can see quite a few other uses for it in the future. Review to follow......
