What tool/device has improved your accuracy the most?

[Ajax]

For me it has to be the Incra Miter Express sled for my table saw along with the Incra 1000HD miter gauge.  I have $500 Craftsman table saw and the accuracy is okay, but not great.  The Incra sled and gauge have greatly improved the consistency and accuracy of the piece parts that go into the furniture that I build (mostly Craftsman style pieces with a lot of M&T joinery).

Bi-focals. I *wish* I were kidding...

I think the combination of the MFT/3 and TS 55 is the game-changer for me.  The old chop saw is gathering dust (and not sawdust) now, and will be donated soon, once I spring for the Kapex.

Funny enough the Guide rails. Almost, everything festool attaches to them and once you align them up they cut right where you have them set.

Not funny at all and I totally agree.  [smile]

However this desire for total accuracy can do ones head in. This afternoon I was resizing some salvaged doors and worrying  about  approx 0.5mm descrepency between centre and ends of a 2040mm edge. Reset the rail join, all is well and tracksaw is halfway down the rails
[size=14pt] when the power fails.  [eek]

No power for two hours, so will return to it tomorrow.

Also, the Kapex UG Cart, with wings, that thing is great with the stops on it for making lots of cuts.. the Talmeter by hultafors is great as well it is basically a locking story stick.

Bi-focals. I *wish* I were kidding...

For me, bifocals were more a beginning of the end for me.  I could no longer be comfortable walking on scaffolding.  I had problems seeing the line when laying brick and block.  I could no longer see plumb and level when setting corners or building chimneys and had to constantly use the levels for nearly every brick/block when setting those corners.

since getting back into woodworking, I think Festools guide rails along with the patience to cut twice and then measure >>> er ah>>> I may have that a little mixed up, but you get the idea.  :

It was an incremental process;
1-TS 55 and guide rail
2-Quality measurement tools: Festool tape and Woodpecker
3-Increase knowledge of the wood products I was using.

the track saw has allowed me to go from close to the line to on the line and exactly a straight line

my dewalt laser line level  has really helped with leveling wainscotting, dado rails,ceiling joists ect

The Woodpeckers SG-WP Saw Gauge, it has allowed me to align my Table Saw top to the blade within .002" and also my fence to the same accuracy.  These adjustments allow me to rip and cross cut stock repeatably with the precision needed to use my Domino Joiner.

TS55 on the track for sawing and hoping that the Incra LS25 positioner I have waiting for assembly will do the same for routing on my CMS-OF/MFT-VL

Edit: Definitely the addition of the LS-positioner to my MFT-VL/MFT3/CMS-TS55 combination has been the greatest accuracy improvement to date. Loving the ability to sneak onto a perfect fit at 1/10 of a mm at a time if needed and bring able to dial back to exactly the same width directly as many time I wish repeatedly. Absolutely rock solid and repeatable.

I am in the camp with the "glasses" and "bi-focal" guys. Digital readouts have help me the most with accuracy.  Digital calipers, digital height gauge, digital readout on my tablesaw fence, digital angle finder.  I even have a digital clock.  I am damn near in the poor house from buying batteries.

 

[dpeagles]

For me the TS55 plus the accuracy of the mft/3 has helped tremendously.  The ole circular saw and speed square just wasn't ever really cutting it.  Pun intended.

Its funny, I used my track saw to cut the top off a 4x4 last week on a small deck.  Smoothest cut on the top of a post I have ever made.  Now thinking I need  the bigger track saw.

 

[RDMuller]

The Woodpeckers squares and triangle.  The eliminate guess work.  Instead of "I think I am close", it now is "Square" or "not square"
