uneven trimming

Michelle,

Try taking a sureform (the 1 1/2" red one") and hold it steady in your
hand and move it slowly to the surface with the wheel spinning. Let it
take off the burrs a little at a time. The surface of the sureform is
larger than the divits so it doesn't catch in the cut. This works great
for removing chatter marks and for smoothing down the coil edges of the
join on sectional pieces. Once the rough spots are gone just coninue
trimming with regular tools.

For the last few months I have been having trouble trimming my foot
rings. I don't know if my method for cutting a pot off a bat or the
wheelhead has changed but I often end up with a small irregular dent in
the base of my pots. When I try to trim this evenly, the pressure from
my trimming tool just cuts even deeper into the indent and I end up with
an uneven foot ring. This happens no matter how I brace my trimming
tools. Does anyone have any suggestions (besides using plaster bats or
a grinding wheel) - This is driving me nuts.

Thanks,
Michelle

I have found that a Surform rasp works beautifully to smooth out these
spots, eliminating the positive feedback/washboard effect that you can get
with a normal trim tool.

(In case you are not familiar with this tool, it is a woodworking tool with
a surface a little like a cheese grater. You can find it at a hardware
store or home-improvement mega-store. I like the one with the red plastic
handle and squarish cutting surface, rather than the long rectangular
ones. They are also great for trimming non-round and handbuilt pots.)
