# Wasteboard surfacing

I switched to the beaver HDZ and am EXTREMELY happy that I did. But after a huge part of the day traming I then surfaced. I was just wondering even if I tramed and leveled will I always still get some shingeling?

Hey, I have a new word to learn. Whatâ€™s a shingeling ?
One note while I am here though :if you trammed before surfacing, I would suggest you tram again or at least verify tramming. If the original wasteboard was tilted, your tram may have compensated for that tilt, that is now gone after surfacingâ€¦leaving you with a bad tram. And if so it could be a reason why you still see marks (â€śshingelingâ€ť?)

Shingling (A guess, but given t that this is a surfacing operation): the surface looks like a shingled/clapboarded house.

If this is the case, then it is minimized by insuring that the spindle is parallel to the z axis, that the z axis is square to the plane defined by the x and y axes, and rigid z axis and spindle.

Getting ready to do mine this week so Iâ€™m following this thread. I figure Iâ€™ll jog a surface in the x direction, jog 90% the width of the bit and then move back. I should be able to see the â€śshingleâ€ť or not if itâ€™s good front/back. I can then repeat it in the y direction to test left and right. Thatâ€™s my current plan anyway

â€śShingleingâ€ť - where there is an actual step in the material, is the indication that the head isnâ€™t trammed properly quite yet. Youâ€™ll always see a tiny bit, but you shouldnâ€™t be able to feel it. Keep in mind that hte HDZ doesnâ€™t have an easy adjustment in the Y direction, only X. That means you need to potentially add a shim under the adjustment plate to adjust Y. I had to add about .001" of material there.

Part of what you will see is that the swirls have an intersection thatâ€™s a perfect line along the axis - thatâ€™s normal, but there should be no step there. The same goes for cuts along the Y axis.

Perfect thatâ€™s exactly what I have going on itâ€™s not a step but the lines are still there. Yup the Y-axis was not too bad I used some feeler gauges to adjust it it was off by .009.
