Hi guys,
I'm using wooden curved stretching jig to stretch mylar (1% ) in one direction along the long straight axis. I'm using strips of scotch tape to attach mylar to the jig. The scotch tape holds mylar for less then five minutes before I lose the tension because scotch does not have good adhesion to the wood. I painted the wood to improve the adhesion but still have the same problem. How do you deal with this problem guys?
Thanks for help.

I use epoxy on plexiglass frames.
In your case you need to use a very strong VHB tape.
Checkout DIY'er CharlieM's site for more info on what type he uses.

Here is a snapshot of his partslist and it shows the model number of the VHB tape he uses from Mcmaster Carr.

gerald its about fixate it to the jig not the panel 🙂
try using clamps, make the wood a bit tacky and then just clam the foil down on it.

Thanks gerald, I studied CharlieM's site as well as pretty much everything that was discussed here which indeed is very helpful and I'm planning to use VHB tape to attach Mylar to the stators. So far I have difficulties attaching Mylar to the jig. I did try VHB tape but adhesion to the wood is still a problem.
WrineX, thanks. It looks like I found a simple solution. I attached strips of gorilla tape to the short sides of the jig, pretty much covering all surface with the tape, let them sit overnight and than used scotch tape to attach Mylar to gorilla tape. In theory tape's adhesion gets better over time. Is been working so far.
