body after one or two passes. Is this a problem that could be caused by backlash?

The lever cap screw is as tight as I dare make it (any tighter and the lever cap won't release). I have noticed slack in the depth adjusting knob and tightened it up to no avail. Also, I have checked the frog assembly and it's staying put. I've flattened the lever cap and cap iron so they mate and checked the iron/frog fit. All seems fine. If I can solve this problem, I'll invest in a Hock iron; please let me know what you think.

You could be suffering from backlash; then again, it could be something else. First, an explanation about backlash.

Backlash is a mechanical issue with things that screw in and out. I first encountered backlash when I learned to play guitar. Whenever I would tune a string that was too high in pitch, I would loosen the tension to get to the right note. After a few minutes of playing, the string would go flat and then require tightening.

But when I tuned a string that was too low in pitch by tightening it, the string would stay in tune for a much longer time. So, I learned that whenever I tuned my guitar, I should first loosen a string and then get to the proper tuning by tightening. The same goes for the depth adjuster in planes. Always adjust an iron to the correct depth by increasing the depth of cut.

If that's not the source of your problem, I would check the frog-adjustment screw. It also can suffer from backlash. Finally, check the dog that moves the iron assembly forward. If it has become rounded over or damaged, the iron and chipbreaker can slip backwards in use. PW
