Great video John. I work in a rock quarry. We don’t use the little one you have. Ours are 20 ft long about 2 1/2” diameter. The hole down the center is about 3/4”. It’s for compressed air from the drill
Thats what that is, I have a length of the drill rod that I didn’t know had a hole in it until I cut it to make a punch. The hole both ends had been clogged with dirt and other crap so was not noticeable. Learn something new every day!
If you lay your drill press vise on it's side, it will keep the work piece perpendicular to the work table and keep the hole from being drilled crooked. Just a tip that was passed on to me. I love the channel and all the great work you do. I'm currently starting from the first video and working my way to the most current.
No worries about the drill rods in the forge at all. TNT does NOT explode when lit on fire. It burns. Rather well, in fact. Growing up in northern Ontario, I knew a prospector who used to like to freak visitors to his camp out by breaking a stick of dynamite and lighting the open end on fire... he would then use it to heat up a cup of coffee. As long as that hole is open at the end, if there IS any TNT in it, it will burn out. Only danger comes if the TNT is sealed at both ends and under pressure. Then, conceivably, it COULD explode if superheated, but the odds of that actually occurring are about on par with winning the Powerball.....
Very informative. I like the idea putting in the holes at the end of the monkey tools so you can see when it's got there. I've never thought of that.great idea. I'd like to get out to the shop but it's before 3 in the morning, I don't think my neighbors would enjoy that. 😁
Good Evening , John I Enjoyed the Video , So very much ! A Project that I am about to Start on , I will be in need of a Monkey Tool at the end of the project ! As for making one , I may just buy the One tool I will need and put making some , on my to do list ! Thank you for the Information and inspiration ! Take Care and Be Safe ! KEEP HAMMERING !
Thanks as always for your informative videos. Have you made a video about hold down tools before? It would be great to get some more info, I have seen references in some old books but seeing someone build and use it is so much more informative.
Hi John. I’m not sure the type of steel they are made of. Each drill steel is very heavy. Two men struggle to pick one up. When they break they fall back in the hole and we find them after the blasting operation. They are twisted up but they don’t break. I’m guessing they have a lot of flex to drill a 5 “ hole 100+ feet deep. I’ll see if I can find out what they are made I’m curious now. Thanks again for your excellent videos.
depends on how old that drill rod is. if it is old then the dynamite back then was probably saw dust and nitroglycerin and just hammering on it would set it off.
I buy most of my tool steel new. But if you want to use spring steel, automotive shops are a good source and for the old jack hammer bits like I often use for monkey tools, tool rental stores often have old ones
IF there was dynamite in that hole when you put it in the fire it would just burn away . The only way it could explode is if you hit it while it was burning.
I will certainly do that. Although it is essentially the same as my other hammer videos, just hammer the peen out on the diamond. I have a couple of projects in the works and once they are done I will get back into some more tool making videos.
