- All materials are precut: strips of 7/16" OSB as at Technique for Ripping Plywood - and laid right under work table.. 2' and 4' 2x4 scabs are also precut. 13" strips, 2' long of OSB - are precut for OSB scabs. 2 ends of 2x4 are precut - 13" long. 16' and 8' long 2x4s are available in bulk. 9' precut studs can also be used - as they provide a good handle for flipping the truss assembly.
- All tools are prepped: Run an air hose with triple divider. Connect a gun with 2-3/8" nails, another gun with 3" nails, and another gun for staples. This saves time so you have all guns available, never needing to connect and disconnect tools. Have a screw gun ready, and wear a Gunnie on your belt to hold the screw gun. Have a corless saw for trimming ends of 2x4s. Have a pry bar (small one) to assist in flipping trusses over.
- Lay the 16 footers and 8 footer 2x4s in the jig. On one side, lay to the mark. Stick out extra material from both sides to allow for a 'lifting handle' on each end. (if using 8' long - handle will not exist)
- Use small scab with screws to attach breaks in 2x4 with a screw gun.
- Insert 13" ends.
- Nail the 13" ends to chords with 3" nails. (Note: cut off the form to enable both nails to be nailed at the same time on each side of each end - right now the form is covering access to bottom nail.)
- Place OSB on top of jig one at a time fixing one at a time at 4 corners. Fix all 3 pieces at 4 corners
- Production! Nail off the OSB at 6" spacing with 2-3/8" nails in bump mode on the nail gun. Don't forget the ends.
- Flip the assembly. Use spacers at ends, then use a pry bar to lift the middle.
- Insert the 2x4 scabs, and nail off with 8 nails per side of break for the 2' 2x4 scabs using 3" nails, and 16 nails per side of break for the 4' scab.
- Insert the OSB patches, and staple using 1" staples. Use 25 staples per side of break.
- Cut off the excess 2x4s at ends.
- Move finished truss upside down to the pallet.
Notes:
- If you run out of nails, you can substitute 3" for 2-3/8", but you cannot substitute 2-3/8" nails for 3" nails.
- Data: 19 min 10 sec achieved on first try on 7/19/25. Key is rapid bump mode with 10 PSF compressor and 60 gal tanks. No slowdown on rapid fire at 2 nps for nails and 4 sps on staples - key is using bump mode on guns. Otherwise you are adding 4x the time on single shot mode.
