I bought an ECE primus jack plane used a few years ago and haven’t quite gotten the hang of adjusting and using it. I’m hoping other plane users can answer some questions and give me advise.
First off, there are these two metal tacks on the bed that I don’t get:
They keep the blade from sitting flat against the bed, making it bend as spring pressure is applied from the rear knob. Is this on purpose? Seems an odd design choice since most of the nice flat bed isn’t contacting the blade. I get a lot of chatter from this plane in use, and I think this contributes to it significantly. I’m tempted to pry the tacks out and give it a test, but they have to have a purpose of some sort right?
Another problem is the “regulator” piece screwed to the chipbreaker. I believe it’s supposed to be used for lateral adjustments. As you move it side to side, the edges push against the cheeks of the plane and kind of move the blade. Unfortunately this movement is never as I expect… sometimes moving it will dip the opposite edge like a stanley/bailey lateral adjustment, but it never holds and a few strokes later the blade will be skewed to one side again. If I tighten the screw attaching the regulator (there is a lock washer below it), the whole plane blade assembly moves instead of just the regulator and shifts the lateral adjustment uncontrollably.
A final problem is the blade is always pushed to one side of the mouth (always the same side) while changing depth adjustments. So much so that it cuts into the wood of the cheek unless I pay attention. I believe the red-painted tension rod has been over-beveled on one side of the cross pin, which puts a slight sideways force on the blade when under tension. I’ve tried hammering the cross pin a little to even-out the non-beveled portions on each side, but it doesn’t change things much.
The only reliable way I’ve found to use this plane is with a cambered blade and hammer taps for lateral adjustment. But even with this results are pretty poor with a lot of chattering and tear out. It seems like the built-in adjustments should work better on a quality wooden plane. Can any fellow ECE owners give me some tips?
