Recently picked up a lev integra used, and either the pin wasn't included, or I lost it, so instead of ordering one and waiting and spending more money than i had to, i decided to make one, here's a step by step for anyone else who has the tools and wants to make one, or see how i did it.
Little bit of background:
I'm big into the DIY stuff, i don't like paying for stuff if i can either make it or do it myself
Side note: I didn't have any of the metric set screws with a 1.5 mm hex key head, so i decided to use 4-40 screws
tools needed:
Metal lathe, both a 3-jaw scroll chuck and a 4-jaw chuck w/independent jaws
lathe centering drill bit (something smaller than 3/16 and appropriate countersink will work as well)
4-40 tap
#43 Drill
#54 or similiar fractional size drill
Materials:
(2) - 4-40 set screws
Metal rod (if i remember correctly i started out with 3/8" rod)
Step 1: Selecting stock
Looks like a winner to me
Step 2: Set tooling carriage/rest so it doesn't hit the chuck and break all my stuff
Note: under and to the left of the chuck is the stop for how far the tool carriage can go.
step 3: Facing the edge. not really necessary, but i prefer to have clean edges
Step 4: Drill centering hole
Step 5: bring out stock and center, I used a live center, but a regular one with some oil works as well, and start turning down, i didn't write down my final diameter, but i was taking roughly .015"-.025" off at a time
step 6: measure after taking deep cuts
since everything looks good, its time to move onto the next step
step 7: take final cut
Note: For my final cut, i take off >.005"
step 8: cut down and move back into chuck to drill hole for set screws (use #43 drill)
Note that I choked up on the drill as much as i could to insure a straight and center hole, the bit may need to be moved out a little bit to drill straight through
Step 10: switch to 4 jaw chuck to drill hole for cable, use centering bit in tailstock to assure piece is centered
Step 11: (not pictured) use centering bit to put small depression for drill bit, then drill hole for cable (if i remember correctly i used a #54 drill)
step 12:switch back to 3 jaw chuck and face down end to remove excess
step 13 (not pictured): tap hole with a 4-40 tap
step 14 (not pictured) insert set screws, install on bike and have a beer
