+Practical Renaissance : I enjoyed your video a lot. Beautifully executed. But the problems you Americans have when you need to cut metric threads is a problem entirely of your own making. The U.S. is the only place on earth that uses a bizarre system of weights and measures invented by the British and abandoned by every one every where except for you guys. Even we the British, the inventors this rubbish, have abandoned it in favor of a beautifully simple and consistent system invented by the French. The metric system.
+Gareth Jefferson So true about U.S. all puns intended. But sadly I still love it's complexity and totally ridiculous amount of time to convert it to decimal, and then if you want metric from decimal you have to do another conversion. LOL, Yep we Americans are totally off our rockers for sure. Best Wishes n Blessings Keith
+Gareth Jefferson Hey I can use either system! Years ago when I was a pastry chef I wrote recipes in metric because A) All the italian and french ones I was reading were, and B) because it's actually a little easier! It's converting between metric and standard where everything gets so silly!! Thanks for watching!
Just found your channel about 3 years too late! Absolutely the best produced and narration I’ve seen. Looks like I have a bit of video time to look forward to on your channel.
Nice, instructive video. Thank you. Technically, it's good practice if the lathe is metric to make any accessory fittings metric also, so there is only one standard.
I just discovered your channel and am now a subscriber great work and great job doing video tutorials.. I am a novice machinist so i am learning some new stuff watching you. Keep em coming!
Excellent work, your presentation, video, sound and editing are very well done. Not to metion the content is interesting and useful as well. Thank you much for sharing your knowledge.
You could have tested your thread by removing the chuck with the part in it, as long as you put it back in the same holes (if I remember correctly, your chuck bolts on). Regards, Matthew.
Nice video. I need to make one similar. The one thing I need to warn you about is, put a handle on your file. The lathe will catch it one day and the tang will be pushed through your hand. It happened to me luckily for me it just went under the skin and out the side. File aside your project looks awesome. Thanks for sharing.
+sam yeates Yeah, the file in the video has a very large rubber handle on it, as do all files used on my lathe and I agree, it is absolutely dangerous to use a file without a handle on any lathe!! Thanks for watching!
Great video. Enjoy all your videos. Informative and well done, and you're not a "know it all". You were definitely resourceful in adding the four (4) bolts at 90 degrees to one another. Another way of doing that would be to hold the piece in a 5C collet - and use the four-sided block in a vise on the milling machine. Or in a Spin Index.
Nice work. I'm considering making one for my lathe eventually so any videos like yours for ideas and tips sure come in super handy. Thanks for the videos, you do great work.
Go and buy a carpenters circular saw with 24 teeth. Fit it centrally to what you've made here and then fit some kind of pawl stop so that as you rotated the blade one tooth at a time, the click and return of the pawl moves your spindle and chuck 15 degrees. You can now use this to accurately make your own 24 angle indexing plate which can be fitted quickly just as is your spider. The more teeth on the 'industry made' circular saw, the more angles. NASA would not be interested in this poor man's indexing rig but for the hobby machinist, its as accurate as you make it.
Loved it, I could have used one of these for some of the projects I've done. I'll keep this in mind for the future. Thanks for sharing. Best Wishes n Blessings. Keith
In your opinion would the Grizzly 7x14 be a good gunsmith lathe.? What's the true "through" hole dimension on this.? I do small projects but don't really want to spend $3500 on a large machine. Just looking for your opinion.
You can check out my other videos to see some of the gunsmithing I've done on this lathe, it's certainly possible but in my opinion this lathe isn't really ideal for it. The spindle bore comes in at 20mm which is something like .787. I was able to run a 13/16 drill bit through the bore to get me to about .813 (probably bigger with the way drill bits cut that deep) but that's really pushing it with the little lathe. There's no debating that a larger machine is definitely better, there are a number of options out there for a bigger/sturdier machine that is just past the $1000 price point
There's a reason gunsmiths make good money. If you really want to give it a try, look into a 12x36, 13x40, or 14x40 lathe. something with an 1-3/8 or 1-1/2 throw hole. Look for at least 2 hp, and at least a 6 inch, 6 jaw, acu-set chuck. Craig's list is loaded with good lathes, if you know what to look for.
Hi sir! Could you please inform me about the 4 jaws chuck and the tool post installed? They seem great! 4" chuck I suppose, it will be my next upgrade together with a quick change tool post!
+malibuu6969 the Tool post is an A2Z CNC aluminum one (don't get it, get the imported steel Aloris knockoff) and the chuck is a 5" 4 Jaw chuck from Little Machine Shop with an adaptor plate for a 7x14 lathe
How do you get your lathe to stop so quickly? I finally mustered up the gumption to cut a thread (M5x0.8) on my jet 9x20 and to my panic when I threw the lathe in reverse it just kept going forward. (I ended up hitting the carbide threading insert that came with the lathe against the three jaw, but luckily no real damage happened) Only later did I find out that I had to turn it off, wait for it to coast to a stop, (This could be a substantial distance) then throw it into reverse for it to actually move back.
wire in an active breaking circuit, it basically joins your positive and negative on your motor to turn it into a dynamo, google active breaking mosfet
Nice little vid, especially the tapping process. Think I would have just bought the screws though, but then again where's fun in just buying everything huh. Great post. Best Wishes n Blessings Keith
+Keith Noneya Nothing wrong with just buying the screws! This was motivated by my purse strings though, I wanted brass for non-marring and the darn things are more expensive for 4 of them than for a foot of hex bar stock!! Thank you for watching, Keith!
A hand wheel on the end of the feed screw is a handy addition for when you do not want to or can not use the power feed. Using power feed on very small diameter turning is undesirable. I am not clear as to what the imperial lead screw has to do with the *procedure* for threading. The only affect should be thread pitch error which is minimal. Parting on the back side with the chuck in reverse can be helpful.
I've been planning to make a spider for my Grizzly G0765, to do barrel work. Can you tell me what the thread pitch is on the spindle? Thanks in advance.
Practical Renaissance,I purchased my 7x14 lathe from Micro-Mark in 06. Until I took the spindle housing apart did I realize that the electronic speed control pickup devise (as shown in your video beginning on 1.00) as the thin multi-segmented indicator which indicates the digital pickup.When I bought my lathe I did not know that the speed indicator and electronic pickup was in contrast to your "GRIZZLY", as mine was safely located INSIDE the spindle housing, far away from grease, dirt and physical damage. I wonder how many other mini lathes are configured this way.I also wonder how many lathe motor mounts are configured through the front of the spindle housing, while others are found to be parallel to the drive shaft. Can anyone comment?
I've got that same band saw. I use it both in the horizontal and vertical configurations, and it's slicker than a cucumber in a women's prison. Best $259 I ever spent.
Nice job sir. But why did you bother with cutting oil while doing the brass screws? The crying noise you hear is not the tool suffering, it's just the brass grain being torn by the tool and the metal rubbing snugly against the cutting face. No problem...
Very clever index lines. I've been a machinist for 23 years and never thought of that. Good Job!!
+Stacy Simon I take that as high praise, thank you very much!

toolpost seems to vibrate pretty well? have you made the mods for the lathe to actually make toolpost better etc?
Very encouraging. New to metal myself, bandsaw looks almost indispensable.
+Paul Mcnulty The bandsaw is worth every penny! I may do a video on it in the future, I absolutely love it
love your work I have a similar lathe and have been planning same project.
+Shaun Tucker Thanks a lot! I wish you luck on making yours!
looove the die tool. great video
tank you for your work , what is the metric thread size you made for this mini lathe?.
Nicely done.
Nice work. I'm considering making one for my lathe eventually so any videos like yours for ideas and tips sure come in super handy. Thanks for the videos, you do great work.
+Curt Warkentin It's a surprisingly easy project and you'll be happy you have one the minute you need it!

Nice project.
What brand name and model number is the QCTP you are using? What size chuck is that? Thanks
How big of stock can be fit in the spindle hole of that lathe. I'm looking at purchasing a lathe and would possibly be doing some Gunsmithing on it
Look for spindle bore - this lathe's spindle bore is 0.78" (20mm)
In your opinion would the Grizzly 7x14 be a good gunsmith lathe.? What's the true "through" hole dimension on this.? I do small projects but don't really want to spend $3500 on a large machine. Just looking for your opinion.

+Practical Renaissance 5"? Wow! Does it fit?
malibuu6969 nope. Obviously doesn’t fit.
What depth of cut did you use for the internal threading?
I really liked the tail stock Die holder ........ I have to make one for my shop

Can you explain why brass bolts are better there than usual (even the black strong) bolts?
Thanks
Makes sense. Thanks

Good work, what is the lube you use for BRASS?
+Mukhthar Ahmed I don't work with brass very much so I'm not an expert but I haven't needed any lube for cutting brass yet! Thanks for watching!
Brass does not need any lube, just another rake angle than steel. So if the cutting/finish is not satisfactory change the rake angle.
I've been planning to make a spider for my Grizzly G0765, to do barrel work.
Can you tell me what the thread pitch is on the spindle?
Thanks in advance.
+saelliott69 Yeah it's 27mm x 1.5mm!
Thank you.
great one.
Where did you get that tail stock threading die holder from?
+thomasjbuckner I made it! Check out the video ruclips.net/video/l7vNn3f1GBA/видео.html
I don't have a four jaw chuck, I'm thinking of making one of these to hold in my three jaw to center something up better if I ever need to do that.
Are those plastic gears I can see? 🤔
love it great video
Why not install a small chuck instead of the spider ?

Try and part off with the tool up so ur compound and cross life don't pull up they get pressed down also maybe check ur gibs seemed possibly loose
Great stuff but I hope you got a better lathe
I've got that same band saw. I use it both in the horizontal and vertical configurations, and it's slicker than a cucumber in a women's prison. Best $259 I ever spent.
LETS !! SEE !! YOU !! MAKE !! UP !! A ! SPIDER !! WITHOUT !! YOUR BLESSED !! LATHE !!!
many thanks for the tips :-)
Do I really need the spider,or can I thread London pieces without it?
It's going to be a lot easier to make a concentric thread with the spider, that's for sure
Cool.thanks
will this work on a harbor freight lathe? thank you for sharing!
same lathe, different coat of paint
very cool ..
Nice job sir. But why did you bother with cutting oil while doing the brass screws? The crying noise you hear is not the tool suffering, it's just the brass grain being torn by the tool and the metal rubbing snugly against the cutting face. No problem...
All god and fine, but What is that music sound? Couldnt hold out for the END of the video.
wow your tool holder was flopping around like a rag doll in a lil girls hands
Has anybody ever told you, you sound like Charlie Sheen?
And great work!
great info thankyou but please get rid of the music it drove me potty whiile watching
Ok good. I should asked first.
