Thank you for usefull infomations.
I tried to make sub-base.
A center hole is too small, I wonder.
I used 5mm acrylic plate. A little bit thin ? Next time, I try 8mm.
But I used a wide plate, so convienient I think.
I want table ...
As next step, I will try to make center hole for template guide.
But problem of friction-heat is not cleared when I use fostner bit.
Only makeing drill slow-speed is a good way ?
I were glad if you could teach me a good way to use fostner bit againt acrylic plate. |
