re: Double sided tape

I just use whatever carpet tape they have at Menards.  I think it's Duck brand.  I keep both the regular and the heavy duty stuff around, depending on what I'm doing. The XFasten was actually what I tried and didn't like.  For my use case (CNC) it didn't feel rigid enough.  The tape is thick enough and the adhesive gummy enough that it wasn't as rigid as I desired for CNC.  It also loses its hold at a relatively low temperature, so I couldn't use it with aluminum.  For template stuff though I bet it'd be great, because it did a good job of peeling off afterwards for me, usually.
