I will tell you what I just did… I ordered a frame jig yesterday. Why? Because I built 100 frames on Sunday and I can’t even tell you how long it took. Manually building them.. gluing, stapling… I couldn’t even get a rhythm. I just saw a video where a gent built 10 frames in 8 minutes using the jig. 10 frames probably took me 25-30 minutes! I wasn’t really timing but it was a LONG time… and my time is worth buying a frame jig!!
