I have learned that I am rather horrible at precise measurement with my bosch 4100 table saw fence. I have seen the digital display on other bosch’s. Any help to make accurate cuts is welcomed so went looking for this unit. 85% of the places have it out of stock or no longer available. Did find one at Summit Racing (why does a auto part store have it? who knows) for $114. Would this be a bad investment?

If it’s repeatable and measures to the .001 I’d buy it.

repeatable.. hmm. good point. never thought on that. ” infinite repetitive cut capabilities ” is what it says in the description.

measurement: i think i read it goes down to 1/32 inch

I don’t use the one on my 4100 as much as I thought I would.

Personally I’d keep the money and figure a way to get repeatable cuts.

As it is my fence toes out 42 thousandths and I don’t see how the digital

read out would help anyhow. Live and learn.

i have a good assortment of micrometers, dial calipers, dial gauges, etc. maybe i need to go searching for the proper way to measure for a cut in regards to fence location. i do foresee adding in a micro adjust feature on it eventually

LOL, sure but I don’t know how to take it out cause there’s

some cable running through the assembly and I’d mess it up

if I had to take it apart.

I’m not sure if I’m missing something, but I would just use either a metal ruler like the one in a combo square, or setup blocks. You shouldn’t need to spend over $100 on a digital gauge to get accurate results on a table saw. I rarely need to be within a thousandth when building things out of wood unless I screwed up and had to recut a piece that needed to fit perfect, and even at that… just get a bigger hammer or clamp the heck out of it! LOL

I used to get frustrated when trying to build things from plans because I would cut all the parts out at the specified numbers, and it wouldn’t go together. I finally realized that if you are off a few thousandths here and there, by the time to assemble 10 parts, I would be over 1/8” off. Now I cut parts to fit as I go since there isn’t a table saw or operator that I know of that can cut things perfect. Just make sure that parts that need to be the same size are all cut at the same time before moving the fence.

I don’t know if you are familiar with The Wood Whisperer, but he did a video about relative dimensioning that explains that cut as you go method I was talking about. Here’s a link to his video: http://www.thewoodwhisperer.com/videos/relative-dimensioning/

If I totally missed what you were talking about, sorry for being off topic. If not, hope that helps a bit. It completely changed my woodworking when I realized what was happening.

+1 to scooby’s comments (somebody get the dude a scooby snack)

I have the 4100, I do not have the digital display, nor do I think it’s necessary. I always set my fence, then use my combination square to double check. I think I might give the fence a tap to adjust it a hair 1 out a dozen times. I cut to fit very often, and just when I think it’s almost right, if it’s too big, I’ll do a couple swipes on a shooting board, but I rarely find that precision necessary, usually I just go back to the table and reset the fence with the workpiece between the fence and the blade, then run the piece again.

Repeatable cut methods I use :
- Cut all similar parts at the same time.
- Use a crosscut sled with a sliding stop
- Clamp a piece of wood to the table/rail so I can move the fence against it, back to the same spot.

It just seems like a lot of money to spend on something that you can do with a combination of a metal rule and good cut planning.

after some PM’s, I now understand some things better. I’ll pass on the digital display. If it was $50, I would buy it but it’s $115. I feel stupid to admit this, but it may help others: I bought my bosch 4100 used and already assembled with no instruction / assembly manual. I have used it for 2 years with common sense successfully. The issue was not understanding how to use the rule tape for the fence. When I had the extension wing fully closed or fully opened, the indicator was always 2” or so off. I just chalked it up to original owner just slapping the rule tape in place without care of anything. It never occurred to me that I have to zero out the fence by MOVING the extension table so that both the rule tape and indicator align. I feel stupid I never realized that til last night, but glad I spoke up and asked a stupid question.

The bigger issue is using the rule tape at all. I have never trusted them on any saw. If you change the blade then the tape is never perfect again. It’s simpler to check it with a tape measure and be done.

I agree with Joe:

It sounds like you got things going on track now.. but Shawn brings up a good point. I never rely on the rule tape when I’m making a cut that has to be accurate… but I have an infestation of rule tape gnomes that come in after I leave and move the marker.

Good advise all around. Outcome resolved.

I thought I might chime in with a couple words. 1) Hand 2) planes

When it needs refinement into the thousandths… Nothing compares to a well tuned hand plane, and using it rivals the joy of sex.

So I exaggerated.

Still… For that wonderful fit… Sneak up on it with a handplane. (Using the generic term because there are many planes with specific functions.) Just like Apps; “There’s a plane for that”.

I bought my saw as a 4100-09 new from Lowes with a match/beat price guarantee, plus a 10% off coupon, so it came out to around $481. Then I ordered the digital fence attachment through amazon when they had a $20 off $100 Bosch order sale, so it came out to around $81. It came with all the parts to upgrade a 4100-09 to a 4100DG-09. It’s been a while since I did the upgrade but it took less than an hour—would have took less time if I had smaller fingers. That cable mentioned goes through a metal tube/channel and connects to a part inside the channel the fence glides on. As you move the fence, it pulls out more cable. (IIRC) I believe you can still remove the fence from the saw without worrying about the cable—I don’t think it connects to the actual fence, but recall a magnestic connection between the digital unit. Just slide the fence up against the saw blade, press the button to zero the readout, and move the fence to whatever size you want the cut to be.

I haven’t used the saw much but I bought it with a Bosch 1617EVSPK Router kit with both fixed & plunge bases and the molded case, as well as a bunch of lumber at the time, all receiving the 10% discount after matching prices. The digital upgrade had free shipping and no tax. Is it nice to have? Sure. Is it absolutely necessary? No.
