I just bought a Porter-Cable 557 type 3 Biscuit Jointer.
The first thing I noticed when I pulled it out of the box was some
wobbling between the top handle and the rear handle. Looking at the
blade, the mouvement is small but visible. Hum...
Using the corner of my table saw as a flat surface and with the aid of a
dial gage, I measured 0.012" of play at the blade tip (I had to
disconnect both lateral springs to keep the blade out). 0.012" is almost
1/10 of the blade thickness!
I figure that in order for biscuit to be useful they need to be
precisely aligned. Is that kind of play too much?
You guys with experience with biscuit jointer, what do you think?
I didn`t fired it up yet, I prefer to wait for your sound advice.
