Nice to see that people are still using the spline method. That is what I did to retrofit a screen for XD fabric back in 2009. I was listed on here as mjg100 then. smile.gif I see Chris still has the link up under his DIY section. This method will get the screen tighter than a drum and it stays that way for years.
You know, as much as it was a pain installing (and really only due to the way I built my screen), it has not lost any tension. At all. It is still snug as hell. I would recommend splining it for sure. That way, if down the road you want to upgrade, you just take out the old material and spline in the new. The next latest and greatest Seymour DIY screen material is next in line for my frame.
