Hi, my name is Russ....and...ummm.......ahhh......I've broken a few drawbars on my Lagun.
Yeah, it's not too difficult to do actually. I believe the threads on drawbars are 7/16-20.
You know when you've got a half inch end mill in that there R8 collet and you're going to be slotting some steel plates, and you don't want the cutter pulling out so you give it just that liiiiiittttlllleeeee bit extra UMPH......on the wrench???.......well, that's the just the start..........
Then a after a few months......you got that same job again, or something similar, so again.....just a little more UMPH.....but this time the "UMPH" turns into, "HUH"?......and you realize that CRAP......I'm turning it in the right direction but it's NOT getting any tighter......soon after that, "CRAP" turns in to "SH!T"!!!!!
I just stripped my drawbar!!!
I've bought two kinds before. The cheap ones, where the long rod is fit into the hex and pinned there.........right where they break!!
And the expensive kind, (just north of $100) for a one piece construction. Those I find work very well, because if you do strip the end, a quick trip to the lathe with a proper cutoff and chamfer tool and you're back in business a few minutes later.......ummm......with a little shorter drawbar that is.......
Best Regards,
Russ
