Sine base Part 2

[@donaldfisher747]

Watching you and the shaper....memories of my first day in the Toolroom! I wish I had your special tool holding jig!

[@erchata]

lastima que no entienda el idioma, pero me encantan tus vídeos y la excelente meticulosidad Y precisión en todos tus trabajos excelente gran profesional me quito el sombrero chapo saludos desde, BARCELONA ESPAÑA,

[@erlingweiseth2774]

Another piece of excellent craftsmanship, Stefan! You've set the standards, once more!

[@sevenninthsfabmachine]

Looking good ! I didn't know that oil or soluble coolant had different effects on the size of reamed holes. That's very useful information. And I like how you can rotate the sine base to get an easy 45-degree angle. Your approach to taking a traditional sine bar and making something that's more practical for standard shop use is very creative. Awesome problem solving!

[@StefanGotteswinter]

Seven/Ninths Creative I would love to say that its entirely my idea, but I saw something like that - much bigger - somewhere else as a commercial product, but I cant find it anymore. It was about the size to be clamped in a Kurt Vise and could even hold a NC rotary axis. Thank you very much :)

[@StefanGotteswinter]

Seven/Ninths Creative We learned and tried that during apprenticeship, our old master showed it to us with way lube and soluable coolant - I always rember that lesson :)

[@jimmilne19]

Great build. Super nice tool you have made. I enjoyed this video. Your running commentary is so very useful, adding information to the visual information. The reamer not bottoming out tip was something I hadn't thought of. Thanks!

[@StefanGotteswinter]

Jim Milne Thank you, I also like the way how that thing comes out so far :) I learned the bottoming-out thing the hard way... ;)

[@ShevillMathers]

Taken my appreciation of metal accuracy machining to a new level. Fascinating stuff. Thank you for the explanations and detail.

[@StefanGotteswinter]

Shevill Mathers You realy where binge-watching my videos, werent you? Thank you very much, I hope you enjoyed and took at least some valuable information out of them :)

[@ls2005019227]

Great video on a tool that will add ease and save time in the future. I plan to make one myself. Your detail in setup/operation of the shaper is appreciated; I have a 14" G&E that I really enjoy.

[@shortribs11]

Outstanding work, thanks for sharing.

[@randallsimonsen1907]

Beautiful work as usual. Pardon my ignorance but why not rough the part on the mill with fly cutter or used end mill and save time and tooling? He is so modest sometimes I think he forgets how much he knows. Simply a joy to watch as with most who are good at a craft. Advice, not from a non machinest, but I will warn you, your gonna need a bigger house soon. Tony sent me, thanks.

[@MatthewTinker-au-pont-blanc]

Thank you, I learnt a lot from your careful explanation. I have some shaper work to do, seeing your shaper run inspires me! Thank you again, I really enjoy your videos! Regards, Matthew

[@StefanGotteswinter]

Matthew Tinker Ha, thank you, as I enjoy running the shaper a lot I also like to share it. I often get questions why I still use that thing in my shop, even if I have a pretty good milling machine :) Makes me very happy if you can take some inspiration from my video :)

[@ROBRENZ]

Very nice work and videos on the sine bars.

[@pierresgarage2687]

Hi Stefan, In America a "mouser" is a huge cat that hunts lots of mice and rats... You measure from 50 to 75 with it... lol Great project and I can appreciate your attention to precision and details, just have to make time to get more projects on the run... Cheers, Pierre

[@StefanGotteswinter]

pierre beaudry Haha, using a cat to measure is always a bit..furry. "Mauser" is the manufacturer of my 50-75mm micrometer :)

[@pierresgarage2687]

I knew, but couldn't resist... lol Sounded much the same...

[@StefanGotteswinter]

..And I learned something! Never heard the term "mouser" for a cat before :)

[@andyZ3500s]

In France a hundred years ago a mauser was something my great grandfather worried about daily. Of topic I know, but that was one hell of a gun.

[@nder12345]

Thank you Stefan I love your videos in METRIC I am an apprentice fitter machinist in Australia

[@lorenlieder9789]

Very nice shaper work I wish I had room for one in my shop.

[@bulletproofpepper2]

great work and nice video. thanks for sharing.

[@BraveLoch32]

Whoa, I have the exact same Casio calculator! Love the videos by the way!

[@beatrute2677]

Learned so much from this

[@danielwerger5641]

Most excellent Stefan.... Thank you.

[@CJ_LEGAN]

That's a very cool tool. Another item to add to my list......

[@StefanGotteswinter]

CJs Custom Thank you :) Its always making tools to make tools to make... ;)

[@ApukEldar]

Good work Stefan. I'm waiting for a part 3. Don't be lazy.

[@StefanGotteswinter]

Apuk Eldar Already working on it :)

[@artmckay6704]

Beautiful work! :)

[@coldformer1]

nice project and a great video thanks

[@StefanGotteswinter]

Jerry Schram Thank you :)

[@blacksmithbrazil8838]

Very Good, the best ! Blacksmith Brazil

[@Zorgoban]

Plop... Plop... Thanks for the nice explanation of hole reaming

[@StefanGotteswinter]

Zorgoban And always remember, your results may vary - My videos are not real instructional videos more kinda show and tell :) Thanks for commenting!

[@edwardhugus2772]

Stefan...you give yourself too little credit on that point. Your videos are very informative and since I have found your channel, I indeed have learned from you. Abom79, Oxtool and now your channel have become my favorite machining channels. THANK YOU, SIR, for your great ideas. Your sine vice is a really great idea. Ed Hugus, Pittsburgh, Pennsylvania, U.S.A.

[@andyZ3500s]

@@edwardhugus2772 I completely agree with you Stefan is a natural teacher. Everybody has there own style. I watch most of the popular machining channels and a few of the smaller ones, I enjoy and learn from them all. The informative detail and the way Stefan explains the projects sets him apart from the rest and I do not mean to be putting down other channels at all.

[@thebotformalityknownasdale2564]

Stefan what are the pros and cons in starting out with roundstock and cut it down the center ?

[@nordishkiel5985]

Very nice work! Maybe you could engrave the most common sine-values on the backside. This way you could set it up without a calculator, just calculate the multiplication by hand. Or you could engrave the exact measurements between the pins for better accuracy.

[@StefanGotteswinter]

Nordish Kiel Thank you! Not sure if I will engrave the sine values onto the base itself, but I will for sure put an table with common values in the wooden box that I will make for that thing :)

[@carlosrobertomonteiro7255]

00:08 Amigo, teria como por favor me passar mais detalhes desse suporte para bits que você usa na sua plaina? Eu gostaria de fazer um.

[@DavidKirtley]

You should also measure between both ends to the bottom hole that you used for the 45 degree to verify that the two directions of pins are perpendicular.

[@StefanGotteswinter]

David Kirtley Thanks for that hint - I will check that too!

[@davidewing9088]

I have had to watch this a couple of times to understand your technique - as I understand it, your rough pass on the shaper was a horizontal feed. However, when you used the dial indicator to reposition the table, the feed was then vertical - can you confirm this for me?

[@daki222000]

I would imagine if you cut the circular shape on the bottom you loose a lot of clamping area for your 45 deg. setup. nice video. thanks.

[@StefanGotteswinter]

Flip de boer Youre right, but there will still be a good ammount of material below so I dont worry to much - And its realy no tool for heavy roughing cuts :)

[@gz44gzzg]

Hi, I'm just wondering what did you do for screws on that CNCed mill/panto? Does it have ballscrews or did you modify the acme nuts?

[@robertburns2415]

If you use the calipers and 0 the calipers on the vice width then when you measure the slot it will give you a direct negative reading of the amount of material left to cut.

[@tuscanland]

I still wonder why yo sold the CNC mill, the spindle of it sounded so nice.

[@ronkluwe4875]

Stefan; Looking good on the sine base. What about adding 2 more holes so that you can get an automatic 30 or 60 degree angle, same as your 45 degree angle. Those are common angles and might make the base more versatile. Just something to think about. Regards; Ron Kluwe

[@StefanGotteswinter]

Ron Kluwe Hi Ron, thanks for the Input and its absolutely something to think about, I will draw it out and take a look how it fits into the overall layout :) Greetings, Stefan

[@OmnieStar]

Got any tips on finding a good lathe to buy? I wanna buy used, to save money and to give me something to "fix" or make shiner lol. But i can't seem to find a good place to look for them in then. Got a website or anything? craigslist is a bust for the last few months. I'm about to break and buy one of the cheapy chinese ones T_T

[@erikisberg3886]

Hi Stefan, just a comment on Your terrible precision between the 60 mm center holes. The dowel pins I buy are usually H7 which means that a 6 mm pin would be about 1/100 mm oversize. So that means Your center distance between the pins is spot on 60 mm if You mike the outside of the pins to 66.01mm the way You did. You see, You are not capable of less precision then that.... Best Regards and a Merry Christmas from Sweden

[@ErikBongers]

27:15 "This machine has gas scales...". Did I misunderstand that? What are gas scales?

[@ericg7044]

Glass scales. It's a type linear of encoder that uses LED's and optical sensors to read a linear position. Used to track the position of the mill table very, very precisely and outputs the reading on the DRO display.

[@phpn99]

The ASMR is strong on that one.

[@Ujeb08]

Good job Stefan. It's going to be a nice little tool! Did I hear you right that the block you were machining was prehardened. If so, what would be the rockwell C hardness?

[@StefanGotteswinter]

Ujeb08 Hi! The datasheet on the steel (1.2312) states something around Rockwell C - Not like glashard or filehard but it stands to daily abuse way better than "normal" steel - And that stuff machines like a dream. Freecutting, the tools last in it a long time, pretty low internal stresses and gives good surfaces - Normaly its a moldmaking steel :)

[@thetooth]

I too like to leave five tenths of a mm for finishing to size

[@mpetersen6]

I know the shaper is long gone to a new user but didn't you just once say "this thing needs a DRO"

[@AustrianAnarchy]

Skookum!

[@numberkruncherr]

"Two times half the diameter"... so that would be the diameter then :)

[@robincox8902]

No music again 👍👍👍👍😂😂😂😎

[@StefanGotteswinter]

Because thats a stone old video.

[@Robonthemoor]

Stefan Gotteswinter & I like it 👍with no music even better👍👍👍
