I just acquired a 15” Taiwan Invicta style 4 post planer. It works
well but the height gauge is off by 1/8” and there doesn’t appear
to be any way to move the scale. This degree of scale error
seems pretty weird considering the decent manufacturing
otherwise.

Any clues?

I looked at a few Invicta style planers and unless you have something really unusual you should be able to adjust the pointer rather than move the scale. At least that the way my four post Lobo 20” planer and every other planer I’ve seen work. It’s hard to know what to say without a model number or photo for reference.

It doesn’t have a pointer. The scale disappears under the upper
rim of the post sleeve. If it were “off” by 1/8” going the other
way I could install a pointer, but as it is the mark is vanished.

I have no idea how you’d calibrate that without replacing the scale all together. I’m assuming it’s a used machine and have to wonder if this was a modification by the former owner to compensate for any jigs or sleds he might have used with it. I’d contact him if possible.

This is what shows up when I search Invicta. Here’s a link to a manual that may or may not be helpful. It’s for a 24” machine but the controls will be the same, this bad boy has a spiral cutter head. I was surprised to see that.

Does it rise and fall on screw columns? Just wondering if it may have been rebuilt at some point and not been put back together quite right.

That’s an interesting idea. It looks rough but the knives
came to me sharp and there is not perceivable backlash.
It’s a no-name (well, King or something) Taiwan planer
from the 1980s or 90s.

I can put a DRO on it easily enough. Probably a lot less
work than taking the chain off and trying to calibrate
the scale that way, if that’s even how it works.

...brings up the idea that maybe the chain broke or
something and was repaired without it occurring
to the repairing person to recalibrate to the scale.

Have your say...
