Can someone suggest feed rates for cutting sign blanks from Trupan. I am running a PRT Alpha wtih 5HP spindel. I plan on using a v-bit to bevel the edge and a 1/4 compression bit to cut the rest. Thanks in advance

Todd,
For a 1/4" up-spiral I went 4 ips at 1200 rpms to v-carve and pocket a college logo for a friend. I used a 3/8" straight bit at 1200 rpms at 5 ips to cutout some speaker cases. Both is Trupan. Hope this helps.

Thanks Andy,
Any chance that is 12,000 rpms?

Yep, 12,000 rpms. Sorry about that Todd.
Thanks for catching that Gerald.
