I see that there are clay extruders for PMC, but will PMC work
with a cake piping tips?
You can modify the syringe tips to make cake piping like tips.
Here’s a link to instructions for making your own extruder, for
$5.00 or less,
Instructions by Hadar Jacabson, and yes, you can use cake piping
tips with it.
I also like the Makin’s extruder, because it’s a screw press, and
you can extrude hollow tubes.
