I absolutely enjoyed watching the two part series, there's nothing wrong with making minor mistakes ,we all learn from small hiccups.nice save .
Thanks for watching and enjoying! :)
Came across your hammer project and I really enjoyed it thanks
For some odd reason this is relaxing and almost therapeutic to me...love the hammer. It looks amazing btw
very impressive!
I will have to make one for myself, once my lathe arrives.
it's funny how 3 million people watched the Part 1 and only 500,000 were curious how the hammer turned out.
I love the idea of holding a small part in the chuck with the die used to thread it! Thank you! Also, I noticed that you do a fair amount of sanding on the lathe. It might be a good idea to protect the ways (bed) with a cloth so that the grit from the sand paper doesn't get on the ways. Otherwise, this could cause premature wear and loss of accuracy over time. Great job on the hammer!
You have made a work of art dude. I'm impressed with your ingenuity and candor.
Turned out nice. Watch how you have your tool oriented, especially with brass. Having a large surface coming into contact with the shoulder is a quick way to dig in and break a tool and yank the work from the chuck. I bought that same quick change tool post, the super cheap jinwen, and you definitely get what you pay for. I just upgraded to a Tormach OXA from little machine shop, and I'll tell you it's the best $140 I have spent in this machining hobby. It totally changed the lathe, it's more rigid, easier to adjust, and the tool holders are all hardened steel instead of aluminum. Look into one.
Thanks for the tip. I agree with you on the tool post, it wasn't intended to be a life long part but just something that was better than what was on there in the mean time. I'll definitely look into that one you suggested when I'm ready to upgrade.
Mount the brass or acetal part on the aluminum hammer head after the thread is made, and then chuck the whole thing on lathe to true the surface of brass or acetal.
Gotta love the Ron Jeremey music in the background!
Pop it back on the lathe by the part that goes into the head and touch up the knurling from where the chuck marred it. Great video!
Thanks so much! That's not a bad idea...
Great job on the hammer! Something you might try, after you knurled it, maybe drill some of that acetal to use as a crimping holder so you don't crush the knurl marks back in the chuck, place it between the hammer handle, and the chuck jaws.
Josh Speer good point. I keep a few strips of cut op soda cans in my toolbox for this very purpose
That came out absolutely beautiful bud great job on that awesome channel sofar keep up the awesome content bro
Thanks so much!!
I love things like this....cuz rather than going out and spending hundreds on specialized equipment you can spend a fraction in materials or nothing if you happen to have it hanging around.....amazing craftsmanship.
Also on that dowel have you tried a scrap piece of leather wrapped or glued to it for polishing? I've used leather to great effect with polishing compounds
No but that sounds like that'd provide a really nice finish. I'll have to try it. And thanks so much for your comment and support!
Cool design. If you cross drilled a hole on each hammer face you could use a spanner to get them on and off.
I always enjoy your youtube videos ,this one in particular has inspired me to make a drawbar wrench.
That's awesome to hear! How are you planning on making the square parts?
I already bored a hole for a 17mm socket ,cut the end of a ratchet(removed the square tip/male end) that fits in the bored hole so I can attach the socket in it, the other end of the hammer is going to be like yours with a brass removable end.thanks for your interest.
Cut your treads using the lathe. Provide a relief nearest the head and power the chuck by hand. Use slide for advancing depth, back off after each pass but keep it locked and reverse chuck by hand.
This is beautiful. Acetal copolymer looks so black and so mechine like.
Love your channel, im going to attempt to make this hammer. Thanks for the inspiration
I bought a tap-and-die kit that looked like decent quality. The Dies are hex like yours. I could not start them no matter what. Based on what I read, I think they were "thread chasers" not cutting dies. It makes sense as the kit came together in a plastic case, and it looks like exactly what you would keep in a tool box, and possibly use as needed on a job site to clean up some existing threads.
I then bought what was for sure a cutting die, and it worked fine. It was round, not hex, and had a slit cut to adjust cutting depth. It was HSS.
You are correct!!! the hexed nut die is for cleaning the thread up after its tapped! (Thread Chaser) The tapping die is smooth with a notch for the die wrench! This is basic Tapping! You have a lathe should have just used the lathe to make threads . I am surprised it took this long for someone to mention that!
Very Nice thanks. It will be one of my first projects when I get my new lathe.
Let me know how it turns out! Thanks for watching :)
Good progress. Now try your hand at tapered arbors. Try to make them fit your tailstock. If you have enough travel in your crosslide, use that. Try not to offset your tailstock to get a taper.
Make common used drill bit holders and such. A spring loaded tap follower and die holder seem to be in order
Thanks and good ideas! I could definitely use a good die holder.

Cumprimentos
very cool ... what stuff do you use to shine up that aluminum like that ?
You should always do a relief cut at the base of where your thread meets the material to ensure it mates with better tolerance and prevent loosening. Also make the threaded end longer so it allows the die to straighten before it reaches the critical end then cut off the access.
ummm, ok...
umm ok what? He is right jack ass!
that turned out beautifully! great lil project, thanks for sharing!
Thanks for watching!
Simplesmente Perfeito.
Meus sinceros parabéns pelo trabalho e pelo vídeo também.
That's . . . . a bloody nice hammer!! Well done!
Thanks!
I’m a welder not a machinist, so I don’t know much and this was really cool bro. But on our lathes, granted they are a lot bigger, we have a tool to cut the material down in the lathe, instead of the hand saw which would be a lot easier? I’m not sure if you can get them for the smaller lathes but it might be something to look into. Keep up the great work dude.
Thanks so much! What you're talking about is a "parting tool" and I have one but it doesn't work well on thick [for this lathe] material and I only have about 12" of effective work length. Another thing is that if the piece it sticking out too far it makes parting really hard or even dangerous because of flex in the part. Really I need to get a horizontal band saw and make my life much easier.
Great video, nice save on the brass
IF - I were to again build this - I'd machine an additional head from something else (nylon for example) and attach to the handle base - possibly a 4th attached to the top of the head with a different material so I could expolit 4 diffetrent material densities. Just love this build.
Hex dies are for fixing threads, round dies are for making threads.
Nice hammer, when we prototyped the WIYB hammers we went with a stud type mount for the faces, there was too much time involved and too much material loss in machining the threads as part of the heads. ( as well as too many opportunities of messing up) Pierre and I also saw the benefit of having replaceable threads in the event they got damaged .
Cheers
Thanks Phil, I agree with the material loss part of it for sure (hence trying to salvage the crooked brass piece) but I went with that method mostly because I don't have flat drill bits (yet) or bottoming taps (yet) and I wasn't confident that I'd be able to get a mature enough thread deep enough into the face to make it work with a stud.... the good news is that once I get those tools and need to make a new face, I can easily convert this hammer :)
Maybe an endmill, if you have multiple drill bits the same size you could grind one for a flat bottom
That's not a bad idea - I just got a bunch of drill bits that came with a bunch of multiples of each... I need a decent grinder now though.
After seeing you mention Clickspring in a comment on your last video, I half expected to see a super glue arbor when you made the brass head
I loved watching this, awesome. Cool music too.
Thanks! I'm glad you liked it :)
Gorgeous tool you've made here :-) About the only advice regarding machining Acetal is this - use "sharp" tools.
Absolutely brilliant I just love it 👍😄
Looks great! Need to sign and date it.
Might I suggest that next time you make replaceable heads, that instead of putting the threads on the parts themselves, drill all the way though and run a tap all the way through the end this way you actually have 2 sides for when they get damaged. Just make your own threaded rod for the end of the hammer that connects to your replaceable heads. Will cut down on the time to make new heads as well and will save you money in the long run by having 2 sided heads.
Thanks! Thats definitely worth thinking about for next time :)
rin the end of the tailstock quill on the back of the die holder to get it square maybe?? good save, but a little scary. nice result though!
I tried that but it's just not quite the right shape to sit flat on the larger diameter dies. Thanks so much for watching and commenting! :)
отличная работа.
0:40 I'm pretty sure it's not a good idea to touch the material while it's spinning that fast on a lathe, even the slightest fragment or sharp edge will slice your finger up.
Great job
omg!! tats awesome work u did. what a perfection. i need a lathe like this and a trainer like you!! please upload more videos like this. i have subscribed TimNummy. A small doubt i had at last part. the small bit with thread is to cover that hole on top. but y is that you are loosening handle lil bit and tightening the small bit more. better remove 2 threads in small bit. just a suggestion.
Dude. That turned out....AWESOME!! That was really fun to watch. You did a great job filming and editing. This makes me want to get into machining so much more. Great, now I'm going to be buying all kinds of stuff.
Thank you so much! Sorry it turned out to be an expensive video to watch for you :)
What depth of cut can you achieve on your lathe as it looks like you're taking an unnecessary amount of time getting to the desired diameter by doing so many multiple passes. But that aside the hammer looks great good job
If you are going to use your lathe to thread small parts with a die, you need to make a cylindrical piece that is just smaller than the distance across the flats of your dies. Make that 1/4-1/2" thick. Then turn a stem on it to the diameter of the maximum size that your chuck will accept that is about 1" long. Chuck the piece in your chuck and it will give you a good solid square face that will push your die n square.
10:15: It looks like a piece of wood that is being used here, but is it a slip stone?
Truly crafted, Amazing skill!
I have been able to salvage that part with the flame possibly I know some plastics a little flame will get rid of scratches etc.
Now that's a hammer, great work bro.
Thanks!
Hi. Very nice. I'm new to machining and wondered how you determined the balance of the hammer in the design. I'd like to create my own but stuck on aspects like those. TIA
brilliant touch....
turned out pretty nice
Thanks!
Excellent travail
Strongly suggest you look for die holder plans on the internet. It plugs the die into the tail stock and gets rid of a lot of the wobble risk
Thanks! The bummer is I have hexagon shaped dies and don't have the tools to make it easy to cut a hexagonal shaped hole.... it's in the future plans though.
Proper circular split dies do make life easier, that said never underestimate what a file can achieve. You could drill most the material out then finish the corners with a file.
Been away from home for a while so had no chance to melt stuff, or more accurately think about melting stuff and spam the forum with dumb questions. Been home again for two weeks but accidentally bought a big ass (well by my standards) lathe so still had no time to return to my hot metal origins. Will get back to the forum soon :P
Its illegal to complain about your lathe missing parts when your on a forum where people have built lathes from scratch ;)
"better than no lathe" haha yeah for the most part
If you press your tailstock against the back of the die it will help to make the die go on straight.
Also cut a relief in the back of the threads where the threads butt up to the face of the material and that will help you get a nice tight fit to the face. Nice work though, the hammer looks great.
Hey yeah I tried that but it's just the wrong size to sit flat... I thought I had it but obviously I didn't. I saw someone else do a trick where you can turn the tap around backwards and finish the thread all the way to the face so that's what I did instead of the relief.
Thanks for the tips and watching!
Can I get the measurements for hammer
I just started very interested in it I was reading some comments what is a drawbar I enjoyed the video on the hammer absolutely gorgeous true Craftsman
Hermoso quedó espectacular. Felicitaciones
Cool. This is on my to do list as well. Nice project to learn my lathe better! But before I do anything major I need to get a quick change tool post. The clamp and shims I have to use now is driving me nuts :p
Haha I knew I wasn't going to be interested in shims and stuff right from the beginning so the qctp was the first thing I got for it... thanks for watching!
Sir, kindly put more video like this .
Amazing bro!!! The best!!! Do you have a blog??? Thank a lot!!!
My dream always was a metal worker making tools...... Amazing!!!
Wonderful job
Long time since make , But put Copper ( end cap ) - Handle... Lol. For sexy look.
I think it looks great, I’m defo gonna make one. I can’t believe some of the ar##hole comments on here it will last and the ends can be replaced. Keep up the good work. Regards Dave UK
NICE. too good to use.
awesome work bro
Acetal (delrin) can be sanded fine, just gotta use a new paper and some lube. I have sanded/polished a handful of delrin pieces to a reflective finish but it takes more time than it is worth to be honest 😂
Interesting :) good to know!
When your doing an external thread, always do an undercut so it goes flush with the part.
Thanks! I don't know if it's noticeable in the video (or best practice) but I ran the die backwards on the final pass to get the threads closest to the face finished.
TimNummy Yea you can do that but it's always best practice to do that. If you watch an vids of people making or putting a thread on the always do an undercut. That way (as you've noticed threading those bits on) it won't be tight, it'll be loose until you go to tighten it down.
awesome job, great music too
That's actually really nice, do you still have it today?
Very nice indeed. FYI there are commercially available nylon hammer faces in several color-coded hardnesses. They have an internal steel part that's threaded 1/2"-13. They're somewhat narrower than yours, though.
How long does it take to make this hammer?
really nice well done on saving that brass part, I bet it cost you a bit for that brass bar
Thanks! It was the most expensive part of the project for sure.
Great video! Can you write me the name of this machine? Thanks
I really appriciate
U make me wanna buy a small lathe.
Very good
Wonderfull, god job.
U should probably cut the brass using full strokes with the hacksaw as it is faster and more efficient
Thanks, another good video! Good job on the audio too!
Btw, why did you go this route and not face--thread--screw them into the aluminium and hold that in the chuck to finish up the diameter and face?
Thanks! I'm glad you noticed the audio too :)
Honestly I don't think it makes a difference, I think the main this is that turning something that is screwed into something else is never as well centered as mounting it in the chuck directly so it ends up out of round or much smaller than you intended (and off center) so I think I was trying to avoid that - but in trying to avoid it I ended up just using the die to do the same thing ¯\_(ツ)_/¯
TimNummy: nice music at 12:25. aw "
nice background sound while assembly
I'm not sure if these commentators are being dicks or trying to help you out.. I always assume the worst from RUclips comments.
I think the hammer is bad ass and good on you to buy a tool and figure out how to use it!
Haha I'm not sure either, I always try to read them optimistically though.
Thanks so much for the comment and for watching! I really appreciate it!
awesome job, like the music too
hi. i am a new student and i would like to know how to fill the operation procedure shit
What's the martial used in this hammer
Where can you buy this lathe?
Nice one
Very cool, now run around your neighborhood with it like a mad man yelling , I am a Doctor really, now let me check your reflexes.
Wow, good job 👍👍👍👍
Excelent Video, a great idea 💡
Good job sir
Where do you get your aluminum at.
Usually ordered online but there is also a local place by me that sells drops from big orders (as well as big orders)
Hello, are you doing this for sale too? I want this one ! It´s brilliant job.
Badass bro! Great job.
very nice
WELL DONE
Good work bro....
nice job man
Thanks!
Qual o nome desse mini torno?
Nice Project !!
