Portable Strop/Stitching Aid

Tools:

  • Sandpaper
    • 60
    • 150
    • 220
  • Sanding Block
  • Razor Knife/Trim Knife
  • Brush


Materials:

  • Wood block 2"x2"x1/2" or larger
  • Scrap Leather
  • Barge cement (or similar liquid contact cement)
  • Rubber mat (used Tandy Poundo Board)
  • Acetone (leather deglazer)
  • Polish compound (I use white diamond, but chrome oxide or iron oxide would also work, just make sure it is polishing, not cutting compound)




  1. Shape the wood block until it is comfortable. Leave one long/wide side flat.
  2. Clean the leather, poundo, and wood with the acetone.
  3. Brush cement onto the flat side of the wood and the grain side of the leather.
  4. Let dry until tacky.
  5. Press the cemented surfaces together.
  6. Brush cement onto the poundo and the other side of the wood.
  7. Let dry until tacky.
  8. Press cemented surfaces together.
  9. Charge the leather with polish compound, polish something, repeat until a good bit of compound has built up in the flesh side of the leather.
Other Ideas:
  • Single 2"x1" board split into portable cutting/polishing set in a roll up container.
  • Need fresh poundo.



Shot Bag


Shot Bag.

Tools:
  L-Square
  Cutter
  Cutting pad
  Scratch Awl
  Stitching awl
  Wing Dividers
  Trim Knife
  Needles (2)
  Pliers (maybe)
  Binder clips (5)


Materials
  BBs
  Leather 3.5" x 6.5" (2) upholstery/chrome tanned
  Thread
  Handwax

  1. Mark the lenght/width using the scratch awl and L-square.
  2. Cut out leather.
  3. Lay good sides together and position the clips so they allow for stitching along one edge (preferably one of the longer sides). Chrome tanned is very stretchy so it might not want to line up. Use the trim knife to even everything. 
  4. Set the wing divider to 1/8th inch. 
  5. Scribe a line 1/8th inch from edge of the leather, use the wing dividers.
  6. Use the wing dividers to set the spacing
    1. Start at the edge and place one of the legs at the very edge and the other on the line just inscribed. 
    2. Continue down the working edge by placing the trailing point of the wing divider into last divot and bring the leading point down on the line. This makes uniform stitches (both size-wise and linearly)
    3. The last hole may end up not hitting the intersecting line. This is another benefit of using the wing-divider. As there are only 2 prongs, they rotate without impacting all the other holes. Tune the dividers into the work until they intersect the crossing line. 
  7. 2/3rds of the way down and begin stitching.  DO NOT START IN A CORNER. 
  8. Continue steps 5-7 around the piece until only the center 3rd on one side remains.
  9. Poke the remain holes and enlarge them with the scratch awl so they are cleary visible on the inside of the leather.
  10. Turn the piece right side out.
  11. Fill with BBs, funnel may help.
  12. Work the last few holes with the needle and thread (may want a curved needle for this.
  13. Pull tight.
Observations:
Completely forgot to not start in a corner. This made my last corner very difficult to close and a definite weak point. Will likely restitch starting on the last 3rd on the longer side soon.
Needed my portable strop/stitch aid on this. Stitching started to even out toward the end, but still dificult as I was using the awl and holding the piece with one hand. 
Even though I could not see the divots from the dividers, I could feel them with light pressure from the awl. 
Saddle stitch tips. Start with the same side every time, pull the stitches taught every time. By pulling one side up and the other down ~45 degrees from the direction of the stitching it creates a nice ropey look to the stitches.

Removing Handwax from a CrockPot

  1. Set CrockPot to high. Melting took less than an hour.
  2. Place liner into separate pot.
  3. Stir wax to make sure everything is melted, if the resin has not completely integrated. There will be a liquid layer floating over a thicker stickier layer.
  4. Pour into lined pot.
  5. Use paper to absorb remaining wax, prior to turning off the CrockPot.
  6. Put the lined pot into the freezer. This allows the bag to pull free easier.
This mostly worked, there is still a thin layer  of gunk on the crockpot, going to grab some isopropyl and see if this dissolves the remains. Other possibles include kitchen oils as the wax/resin is oil soluble.

Firestarters/Handwax

Tools:
  CrockPot
  Stick

Ingredients:
 2 part  Pine rosin (available here)
 1 part  Beeswax (available here)
6-10 in lengths of sisal rope (3 strand, 1/4in)

To break the wax, freeze for a few hours. (need better times on this). This allows you to hit it with a hammer and it will shatter. Measure wax and rosin into the crockpot and turn on high. Checked ever 5-10 minutes until it was melted (need times to weight data). Stir with the stick to thoroughly combine. When everything is liquefied, continue stirring until the color becomes uniform.

Firestarters:
Soak the sisal rope segments in the handwax mixture while it is liquid. Wait for the bubbles to stop. This means that the waxes have sufficiently penetrated the rope.

Results:
Burn time ~4 minutes, catches 1/8"x1/8" dried oak without issue.

Next Steps:
Re-melt/pour wax into a liner and clean the crockpot.
