I recently got the new version (the third) of the Bridge City Toolworks CS-3 Centre Scribe. Here's a pic of it with two tools which it can replace some of the time.
I did a quick test today as I had to mark the centre line of a piece of wood. I put the CS-3 on the bench with the wood to be marked, noted the position of the second hand on my watch and marked. It took 7 secs and the mark was bang on. Then I followed the same procedure with my Veritas marking gauge. This of course involves the traditional method of guessing half way, marking from one side, then the other, adjust and repeat. 28 secs and the result was a very good but not quite bang on mark. I have to stress that it was good enough for normal woodworking purposes.
Then I used the mortice/tenon marking function of the CS-3 and compared that with marking with my traditional mortice gauge. In each case I set for a 1/2" mortice. 27 secs for the CS-3 (set 1/2" on the tool and then mark) and the result was again absolutely bang on. For the morticing gauge I set the pins against the chisel which took a short while and then marked. Not quite as bang on but you do of course have the option of off-setting from the centre a bit if you want. It took me 40 secs +. I don't think that this is something you can hurry with a traditional mortice gauge and I wouldn't want to. The fact is that you can do it very quickly with the CS-3.
Here's the Bridge City advertising clip which shows how it works. (I didn't have anything suitable for centre marking round wood or tapers.)
I imagine that for most of us speed is not a determining factor but accuracy is of interest. The point about using the CS-3 to mark the centre line is that you need zero skill or experience (I reckon that the average granny or dizzy teenage daughter could crack it in less than 10 secs) and the results are totally accurate. In fact the only quality controlling step is how accurately you have planed the sides of the wood. The CS-3 can't completely replace the other two tools but for the above jobs it is IMO simply better.
I've seen in the past how Bridge City gear sometimes gets a bit of a knocking on here for being a bit blingy and of course expensive but this to me has a spot on functionality which trumps all such considerations. Definitely recommended. (I ordered mine direct from Bridge City as although some stockists hold some of their kit, the CS-3 doesn't seem to be one of the items at the moment.)
The same goes for the mortice/tenon marking. The plate on the back has both metric and imperial scales and it makes it easy to set a measurement "just a hair" above or below a specific measurement.
