So I took the last case of 12 to the front desk, the manager was there, she cut me a look, and even though my bald overweight ass looks way over 18, she checked out my ID. I should probably also mention that here was a large sign on the case 'FOR SALE TO ADULTS ONLY, MUST HAVE ID, NO EXCEPTIONS- WE CALL THE LAW'. I opened the case to check it out and one can had a puncture and had leaked out. I had gone to a local Big Lots and found a case of SUPER DUSTER that they wanted to close out at a dollar a can. I used it to tap the broken bolt piece, and found it would indent it. It is the type of punch that has an end that is 'triangulated'- it's tip is almost like a pyramid. It was plenty long enough to hit the broken bolt. I found a really long metal punch, marked made by New Britain. Practical Machinist- as always thank you all for reading and being willing to help. I know getting off the mountain and tearing it down is the right way, but this is one of those situations where the right way is not an option. If you choose to answer, please accept the real world limitations, and don't reply with 'I wouldn't extend it, I'd just use my magic genie to get it off the side of the mountain and then levititate to my shop and tear it all the way down to to do it the right way'īecause my genie is laid up drunk somewhere in South America, and I'm all out of mana for levitation. What would you do to extend the left hand drill bit ?

I need the bit extended a good 6' to 8' and there don't seem to be any super long left hand bits being sold. Other folks have told me to to weld a piece of identical OD drill rod onto my left hand drill. Then thread the end of my left hand drill bit. I've heard other older guys say I could get a piece of drill rod that is larger OD than the end of my drill, bore it, and thread it.

I've heard there are 'extension chucks' which is basically a piece of hardened drill rod with something like a dremel hand tightening chuck on the end. With it out, I can replace it with a Grade 8 and get this dozer steering again on the left side. With a long enough drill bit, I am pretty sure I can try to drill out the remainder of the cap screw with a left hand drill, and maybe get it out. The left side steering quit due to the fact that the 1/2' cap screw on the clutch throw out bearing collar snapped off. Normallly when I say out in the field, I just mean outside my shop, but in this case it means on the side of a mountain in the middle of nowhere. I am working on a small, 50 year old John Deere Dozer in the field.
