Detailed 24' Truss Production Instructions

  1. 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.
  2. 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.
  3. 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)
  4. Use small scab with screws to attach breaks in 2x4 with a screw gun.
  5. Insert 13" ends.
  6. 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.)
  7. 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
  8. 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.
  9. Flip the assembly. Use spacers at ends, then use a pry bar to lift the middle.
  10. 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.
  11. Insert the OSB patches, and staple using 1" staples. Use 25 staples per side of break.
  12. Cut off the excess 2x4s at ends.
  13. 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.
