Morning all

I have a scroll saw pattern that I would like
to carve in 1/4 aspin. My question is do I use a sled under
the 1/4 in material? Could I use double sided tape on a
3/4 in board of the same length and width, with the 1/4
in aspin on top? Would the carving bit go into the lower
wood?
Do any of you just carve a 1/4 in thick piece?
How does the bit not do damage to the machine?

Sorry for all the questions, I'm fairly new at this.

Thanks for any reply.
