I'm moving the hole to get it centered. When I was done, the hole was exactly where I wanted it, without breaking the bit or the tap. What most do not understand is just how much variations in the metal of the screw causes the hole to walk. The drill has to be steered. Guys that don't do this work assume that the drill will go straight in, just because it was drilled in a drill press. Gunsmiths that do this kind of one off work know better. Just Sayin...............
No Mark, the Internet gunsmiths know better! They would have done it THIS WAY… but don’t seem to have a successful shop or UA-cam channel to refer me to. Hmm. Looks like it 1) worked 2) was time and materials efficient 3) saved the original part as much as possible. 4) could basically be reversed if someone wanted to though not sure why they would. 5) matches the original part as much as possible. NEXT?
When I first tried to drill old iron I was struggling to understand why the hole did not want to get straight, by using a drill press. In old “fibrous” material you need to walk the drill, or use a very short one in a very stiff mounting, what is way harder than steering it by hand. The treads on old German parts are often matching BWS (British Standard Withwort) In real they are often Prussian Inch but that is so close to British Inch that it normally works.
Exactly!! I am a shift millwright mechanic at a large paper mill, and a large part of my day to day is removing broken off machine screws. Steering a drill bit is 100% legit. I am also an FFL/gunsmith (in SC, opposite end of I20 from you) when not at my "real job". Love your work!!
@@andrewluder3477 Want to do a colab video together where we finally get a certain .45 peacemaker back in action? I've had it for a long, long time, now may be a good time....
In the marine biz for over 20 years. Lots and lots of gorrilas in it too. Had to drill out WAY too many bolts rung off by a primate insrtead of finessing them out! In a salt water environment, a little grease, ANYTHING, goes a long way with dissimilar metals. Not to mention the use of grade 5 and higher bolts everywhere! Stainless is too brittle.
As someone who also works with their hands on mechanical objects, it’s refreshing to see others have low dexterity days as well. Thanks for the great videos. Entertaining and informative.
Mark, I don't think you realize how therapeutic your videos are, especially the music. Thanks to you and Bruno for taking the time to make and post these. Cheers
Two things to say. First I actually like when you show some of the little obstacles, or problems you have with things that you work on. Shows how to overcome those obstacles without freaking out and destroying things. Second, I love the put this bit away where it belongs. I do similar things when working on stuff all the time. 👍 I find these so relaxing to watch, and I enjoy you instructional method so much. Relaxed, teaching, without making it sound like you're talking to idiots. Heck even when an idiot tried to fix something before you and made a mess you don't become insulting. Thanks for the videos. 😎
'I don't memorize these numbers I just look em up.' That is the true sign of an expert. One who doesn't burden his mind with figures you can leave for an assistant or search when needed, in short doesn't overcomplicate things.
@@randomidiot8142 he could well have. In this particular instance I was loosely quoting Albert speer on Hitler's ability to remember figures but couldn't utilise them correctly.
I relate to the ham hock hands... I was working with fine screws years ago atop a CFM 56 737 engine,,,PRSOV valve.... when a Small screw fell past the taped 6 inch opening that goes directly into the engine core, screw fell between tape bands...all I could hear was ...TINK TINK as it dropped down. Engine went to the shop for 87 Hours of disassembly.... thank God I followed procedure and had a Union. This was at 2 AM on the flight line... Freezing weather.
Better to disassemble than suck that bolt through the engine. Had that happen on a 727 we'd just finished doing a hush mod. ⅜" bolt turned that brand new JT8 into scrap.
"When in doubt, throw it out." A somewhat underappreciated concept in modern tooling. All the more notable to myself because the man who taught me that was one of the most careful with money that I ever knew. He counted how many napkins he used in a week, but when he thought a tool had worn out of specification, he replaced it and sold the old one to someone who didn't need the precision. He made his living with his tools, so spending money on keeping them as good as possible was worth it to him.
If you snap the tap off in the hole, it's not done, you still have EDM at your service. Also, I remember a shop in Great Britain in the 1970s, that made custom taps and dies in English / American sizes, Whitworth, Metric and some other oddball sizes. I had to make replacement grips for the .455 Webley Automatic pistol from English Walnut and I had to have the Whitworth die and tap set made for the 55° thread form. The company made the tools and they were very accurate and well made. In the end you did a very nice job on the screw. The hardest job working on the old German firearms isn't the actual work on the parts; it's explaining how the parts work to the customer!
There are also the BA threads that got lifted from the original Swiss Thury threads (differing only in having rounded tips in the BA form). They were the first metric standard British threads with a 47.5 degree thread angle.
once again nothing but a pleasure to watch you work sir..thank you and bruno for allowing us want to be gunsmiths the privilege of watching a master at work and the opportunity to learn from you...it's such a pleasure to watch someone who takes pride and joy in their work
I was just geometrically thinking that new screw/plug-stop thing you made for it really should be reverse threaded to theoretically avoid the need for Loctite however structurally speaking it probably wouldn't be worth the hassle considering the tooling you'd need to order for this one-off job. I love how mentally stimulating your videos are, nice job.

@@jonjames7328 not sure if I should joke about only two thousand or only two thousand 'working' parts. Pretty sure on the molecular level we're more than two thousand parts.

Took me a bit to figure out how that barrel band operated. Luckily, I worked it out before the hork occurred. I've actually learned to stop and examine as many times as necessary. Nicely finessed work on the head replacement.
Personally I would have used a drill press. I know how good I am with a hand drill. Love seeing a master craftsman doing his thing! And yes I prefer a dial caliper to the no doubt more accurate digital calipers because the batteries always seem to be dead when I want to use it! My brother's Father-in-law was a machinist and my brother inherited his tools. Not a piece of electronics in the lot!
Buy good calipers. Something like a mittotoyo that actually shuts off will last years longer on a battery than the $15 digital from the hazard fraught.
@@leftyeh6495 Actually my dial calipers are the "good" ones, at least I paid enough money for them several decades ago. They suit my needs well, and I see no need to buy new just for the sake of new. If I was a professional machinist, that would be one thing, but for my use, they are accurate enough!
Hey Mark! Thanks for making these videos! I’m enjoying the lessons on gun stock refinishing, checkering on heat treatment and tempering and drawing temper and softening the metal so it can be drilled and worked. I can see that gunsmithing has a lot to offer.
A suggestion you probably are already aware of on getting that screw piece started from someone who work on very small stuff regulary and has dexterity issues.... first couple of turns are a lot easier with some blue tac. It wont go all the way in, but makes starting them a lot easier.
I stripped and broke the button head my Finnish mosin 1891 barrel band and that damn band is a rare find and when u do find expensive .the damn thing is opposite of rightie tightie . I was thinking about doing this repair but I'm not too good with tap and dies I'm learning on aluminum. I finally found a replacement. Would be nice to do this repair with a bead wield but as u stated it has to turn I racked my mine on this very repair for a while till I just found the replacement lol.
RE: blind hole in the screw, technically, you are weakening it, as the cross section of any material is a factor in strength, however, for the part you are making to fail, one must induce a load that is far in excess of what is needed for the purpose it was intended...AKA, The Stupid would need to be applied.
Hey Mark.... I noticed the couch under the work bench. Is that where you go for a nap and to remember life on a submarine? LOL.... thanks for your service and the great videos. :)
"As with most things German, this is needlessly complicated. Eurgh." I felt that "eurgh" in the little part of my soul that owns a first-generation Walther CCP.
You should try dealing with their machine tools - ugh. They're a nation of watchmakers, so of course "needlessly complicated" is burnt into them. "A German anvil has 70 moving parts, and has to be wound twice an hour"
Mark, hint - get an old pair of surgical tweezers used for threading needle through during surgery, they have locking teeth by the loops and will lock on it nicely. I use for working on electronic locks.
My son has the family 71/84 that supposedly came from my grand uncle that died in the Marines of pneumonia in 1913. That barrel band screw on ours is close to being "horked".
