@cdnkiwi I’ve tried this method, using CA glue. There is no doubt that it makes it easier to ensure that the two layers of tape line up. However, I found that it has the same disadvantage as double-sided tape. That is, the tape that adheres to the work piece is not securely shtuck.
To me, one of the benefits of the blue tape and glue method over double-sided tape is that I have access to both the spoilboard and the work piece before they are stuck together. That allows me to very firmly press the tape onto both surfaces. With double-sided tape, that’s not possible. Gluing the two pieces of blue tape together creates a “pseudo” double-sided tape, with the same inherent issue.
All that said, if it is working for you, go for it. As we often say here, there is no one “right” way to do anything.
Correct, it’s quick and dirty. Not for anything needing precision.

@cdnkiwi Clicking on the pics does not seem to work.
@gwilki Not sure on that, click to zoom works for me in a browser/large screen and in the mobile web interface of the forum.
@altmillal1114 I saw your question above about the contact cement placement. I’m only putting it on one tape, spread thin and it’s getting quite tacky by the time I bond.
As I know contact cement, there’s a correct way (apply both sides, let dry, bring together to get instant strong bond) and a hack. I’m using the hack for a quick and fast stock holder that’s low cost, it works for me. If you need high precision or super strong bond, I wouldn’t use this hack or even use tape at all depending on your needs. This is just another tool in my toolkit, and hopefully it can work for someone.
Happy stock holding

thank you. I had no idea you can use it on one side. I thought that you can only use it applying to both sides
