« Part 2: Putting together those 12 parts Part 3 of Making all wood folding knives series Part 4: Setting,Shapening the Blades and Body »

Welcome back everyone. I must say again that I did not realize how many steps to this until doing this blog. I am not sorry I have made so many of these knives as they have paid a bunch toward buying my shop tools plus I still like the challenge of making each one better. Enough philosophy on with the show.
If you plan on signing or dating now is the time. I do mine with a cheap wood burner.

Now glue the spring assy. to the handle assys. And important point here is to put the back clamp on first then turn knife over and push the front tip of the springs up about 1/16” then put on the middle clamp.

This move allows you to put tension on the blade to spring setting later.

Allow time for glue to dry . This next step can be eliminated if you want as these steps are mostly for looks. This is to put pins in the lower middle handle and the back bolster.

Use a 3/32” bit to drill these holes. #10 copper electric wire fits these holes real tight. Cut some 1 1/4” pieces and sharpen one end just a little, lube with candle wax then push thru the holes with pliers. Cut the protruding ends and grind them flat to the knife body.

Now on to more critical fit stuff. Test that you have freedom of movement in the non-glued portion of the springs. Using a left over piece of spring waste material push against the springs and make sure you have a little movement both up and down. On to preparing to set the blades. On the front bolster make a mark 7/32” up from bottom then another mark up 1/4” up from that. With this line and the previously mark 19/32” from the handle make a cross. This will be the blade pivot hole.
When you place the blade blanks into the knife body and use the spring and a clamp to apply pressure is where you get the spring operating tension.

When you put the clamp and gauge on the blades resting against the springs look to see that you have just enough pressure to push the springs almost up to level with the bottom of the knife body and make sure the blades are pushed back tight against the spring ends. Take this clamped assy to drill press and drill a 3/32” hole thru the bolsters and blades. Remove the clamp and take a break and we will set and shape the blades tomorrow. Thanks for hanging in there. Ask questions if you would like.

I’m gonna have to favorite these as I’m getting busy around the house. At least I still understand what’s going on.
