I ordered some white swiftnerf foam around the same time as 20 ft of OMC's PETG. I have only been able to get a few stefans to fit in the PETG. In all the threads they say you need to stretch and crush the foam to get it to fit, but i've been doing that and not getting any results. What is the best method to make them fit? I searched and got jack.

What is your heating method? Either you are not stretching it enough or you are heating it too much. My method of heating is 10-15 second of indirect heat via blow dryer.

Use med. walled petg.

I've been heating it too much then. like 20 seconds and then putting them in the freezer for a few mins. How would you stretch them?

Use med. walled petg.

A little too late for that.

It sounds like you got some of that larger stuff he had, it apparently fits well in sch80 PVC.

You can stretch the foam by putting it in varying ID tubes (CPVC, Sch. 80 PVC, brass, PETG, etc.) for a day or so each.

Medium Walled is not necessary. My foam will fit thick walled. I have made darts with ever 100 feet or so and have been getting same results.

To stretch the foam, just pull it in little sections (4-5 feet or so) before cutting. Stretch foam to just before breaking point. The blanks that you made after heating for 20 seconds should fit medium walled.

No, he did not received stuff from my bad roll. I would not sell bad foam to anyone if I knew it was bad. All the foam I am selling now is from a new spool. This new spool is slightly larger than my original stuff but no where as bad as the other spool I had previously.

I'll try that, thanks for your input Swift.
