Sorry so long Rachel, but had a deadline for my Mom's 90th Bday party tomorrow and have been out Straight Making Tiny Harleys with that same rig.
Each 3D cut was a.25mm TBN followed by a 30* engraving bit for a total of over 4 hrs a Pair. So thin stock was on a minimum of 5 days. Worked Great for 30 pairs!
NOT sure it's a good setup for a school though(?), as I made it for thin stock cutting(buttons and key fobs .23" thick).
MDO(Medium Density Overlay) is resin coated ply, and most of our highway signs up here are made out of it.
HDO(High Density Overlay) is just ply with a thicker resin coat so I could wax it for easy removal of carpet tape that goes down first.
Then sanded to finish grit(600G) thin stock, is cleaned and Duck brand "No residue" tape applied to stock and both tapes are rolled down Tight.
Then Paper is pulled off carpet tape, stock carefully placed, and then firmly whacked down with a spacer block and a deadblow.
I think it's overkill for you, but we were making thousands of buttons with 7 HDO blanks, and bit was ZZeroed to spoilboard from surfacing to cutout,
so just change blanks, not bits...and sped things up a lot.
Worked great this last month on the project shown in pics.
The spoilboard is a combo of Bill Young's design on this thread; http://www.talkshopbot.com/forum/sho...p-Jigging-Pics
and the addition of threaded inserts has worked Great for 7 years!
It is easy with cam clamps to change out blanks and set up for a new material!
Read somewhere that some teachers and Makerspaces make their students put their material on ply or MDF, so mistakes don't screw up the Actual spoilboard,
but I've never been in a teaching/school environment.
Kyle Stapleton is a teacher who had a full size machine and a Desktop in his classroom...Hoping he'll chime in.
After tomorrow, ask any questions that stump you please....and you'll get faster responses
Have to go pack up the last of the BDay stuff now!
