Topic tags/keywords: tip router planer tablesaw shaping modern digital read out dro precision accuracy repeatability router table bit height blade height height indicator

I see a lot of talk here on router and TS setups. My shop cuts to very tight standards on every cut. I don’t measure errors in 1/32” range, more like +-.005”.

Here are some pictures of some very precise scraps. Can you cut two pieces this tight after resetting between cuts?


When I say 6” I mean 6”!


How about 2-5/8”?


Or 2-1/8”?

This is off the planer:

With digital indicators you can set your router bits perfectly repeatable every time:

Speaking of routers I don’t use a lift, just a plate:

The precision read outs are cheap. The angle block (not shown) is $30, the height gauge $50, the planer readout $80 and the 8” digital caliper was $25

The saw is a griz 715P with a Freud LU83 40T thin kerf 10” blade. The fences on the saw (miter & rip – LS-III) are Incra as is the router table & mounting plate.

This entire rig is under $1500 with enough left for a zci and lunch.

Discuss. (Someone in another thread said that Incra isn’t that accurate, I beg to differ!)

Mark, I’m just wondering if you can count on the material (wood) to maintain the measurements and tolerances you cut to in your applications.

Of course not, but thats not the point, is it?

$25 dial indicator, some $10 digital callipers, couple of steel rules and a few brass blocks works also! Your measuring stuff alone cost more than my table saw :)

I’ll shoot for that kind of precision on my metal lathe… not so much with wood.

Cheers,

The $1500 is for the saw with the fence, router, router insert AND the digital gadgets.

Can you suggest a combination that will repeat tighter for less than this rig?

I don’t have to fuss to get anything to this accuracy. Its the standard that the toolset defaults too. How much error is too much. Errors accumulate, each piece needs to be a tight as possible so the whole will be in spec.

What does everyone think is better? Cheaper?

I know.. I was referring to the ~$185 being more than my TS (well, actually I paid $193.34), not the $1500 total… sorry for the confusion :)

Way too accurate for my simple skill set! My standard measuring device is a story stick.

We had one idjit in here who bounced three saws for “inaccuracies” that were theoretical sine he never cut with any of them and you guys are badmouthing accuracy? Most complaints are ‘not close enough’ not that ‘it fits too well”. Guys spend thousands on saws & routers that +-1/16” is considered ‘close enough’. Its not beyond your skill set, if you can read a calculator screen you can do this. These tools will elevate your skill set and speed up your shop.

But to each their own. ..

Measure with a micrometer, mark with chalk, cut with an axe!

The idea of taking the pin out of my router to drop it out of the case to change bits IS enticing…..but i’m a little afraid to do it because knowing me, before long i’d let it drop onto the bottom floor of the router table.

Yup, still think I will will stick with Krenov’s methods, his stuff turned out okay!

Speed up your shop? Are you kidding me? LOL!

As a machinist, I accumulated such tools over the years. I use them all in my shop now. It can greatly increase efficiency when setting up and tuning machines. I use sine bars to set miter angles and height indicators to set router bits and table saw blade depths. I must admit that I have quit trying to achieve +/-.005 tolerances but I do shoot for 1/64”.

I have to call you out on the first pic though. Your caliper isn’t parallel to the piece. The right finger is sticking past the bottom of the wood but the left is above it. ;-P

I don’t TRY for +-.005”, its how the rig cuts EVERY TIME. When I set any 1/32” measure it ALWAYS cuts +-.005”. There is no effort involved. Set any fence to a 1/32” measure & get exactly that – +-.005. I don’t have to try to get that accuracy, its inherent in the tool!

Can you say the same about your saw/fence?

I can set my saw fence close enough, every time.

When you set to a measure, how close do you hit? Do you know? Do you care? What tolerance do you hold? How close is ‘close enough’?
