I have seen a 2" Double sided tape used by a competitor sign shop and have set out to find out what they are using as their Hold down tape when using the cnc router. I almost resorted to doing some late night Dumpster Diving to find a throw away roll to get a name atleast as to what it is. All I know is what I seen on some stuff they cut for me before.
Stats......
Size 2"
Color... Light Tan
adhesion...Mid tac removalble with little residue
what I have learned that the 2 sided Carpenters tape is not the right stuff. What we need to find is what is called Crepe paper not Cloth Or Film or Tissue paper. the cloth carpet tape from local hardware stores is a woven fiber and I can already tell without my cnc here that this stuff will move. it has good tensil strenght but has shear movement.
I've read about using Scapa 174, Tesa 4970, Shur-tape DF-63 and others. I found that site a memnber found I think it is http://www.actioncnc.com/w123.htm
This site has a tape available for $24 for the 2" roll I want but I am going to find the first distributor of this tape. I found that are the same for $9 ea.
I placed a order for 4 diferent tapes from this site...

and once they get here I will discover what is the right one. I will post my findings here. Like I said it has to be a double sided Crepe paper style tape
or it will be too thick and will have shear (side to side) movement. If any one has experience with this type of hold down with a tape that works good please post links here.
some are asking why do you need tape to hold stuff down?
Simply in some applications it is a great holding source. small cut through lettering, holding multiple thin materials stacked to cut through at once and others. I can show some of the ways and it may open eyes to alternative holdings even for those eith Vacume table.
Thank you

the last link is the one I think it is going to be the winner it is the one that says it is a Crepe Paper tape and I think that is what is needed.
