How I Drilled And Tapped My 4-Links
Just figured I'd share this.. If you are in a bind and happen to have the taps and nec. drills then this is a alternative to take.
I really wanted to run 1-3/4 dom .375wall for my lower link which allowed me to just drill and tap the links to 1-1/4--12 for my heims.. Problem is Lathe I was gonna use is not big enough. Soooo Here is what I did.
I took and cut 1--2.5" & 1--2" piece of the 1-3/4dom . I then used a lathe to drill it out to 1-11/64 and 1-1/4. These where my guides.. U could use a drill press to do this with a little time in centering the piece. That is what I used on the 1-1/4 guide.
I then tack welded the 1-11/64 piece on the end of the tubing and with a variable speed 1/2" drill and a lot of patience I drilled out the 1-11/64 hole. Then removed that piece. Now I clamped the 1-1/4 guide onto the tubing and tapped it using plenty of oil. It works --- but --- if you have a easier way of getting them done ( using weld in bungs, lathe, etc ) I recommend that route. It isn't fun and I don't think my $40 B&D drill really likes it that much.
For the next 4 I'm going to use the mill with a sine plate and just angle the head.. That should work a lot better.
Anyway just thought I'd share this way for the backyard guys that are always looking for a cheaper way.
