Sine base Part 1

[@ydonl]

You know -- Tom, Tony, Pierre, all those guys -- none of them give the really, really good advice like "Always drop your part." Thank goodness for Stefan!

[@ttjarrett]

Good to see they were able to reattach the end of your thumb.

[@chrisstephens6673]

Another great project and I do like the efficient way you work. Mr Bozo always makes an appearance now and then just to keep us on our toes. (English expression meaning keeping alert)

[@StefanGotteswinter]

Chris Stephens Sometimes Mr. Bozo ruins my day :D Then I just have to walk away and do something different - The next day everything is looking bright again :)

[@pierresgarage2687]

Hi Stefan, I love the idea on how the little vise will setup in such a versatile manner, looking forward to the next part, Pierre

[@pierresgarage2687]

Even your pencil is made in Germany... lol Also it would improve friction and reduce force needed to clamp securely, if the ball bearing was ground with 2 flat surfaces, also less stressed marking in the parts... Just thinking loud...

[@StefanGotteswinter]

pierre beaudry The next segment is already shot, now somebody needs to edit it..maybe its me ;)

[@StefanGotteswinter]

pierre beaudry Of course they are! I love pencils and handsketching... The idea of the second flat is not bad, I will give it a shot :)

[@pierresgarage2687]

I find editing sooo time consuming... ;-|

[@crustyolcoot6646]

Hi Stefan. Thank you for your excellent tutorials. I remember my first experience with a shaper as a young apprentice making a v block test piece at tech school. Tolerance + - .03mm. It passed thankfully but I wish KZbin was around back then. It's great to see high quality instruction so thanks again mate. Cheers.

[@bulletproofpepper2]

wow, that is amazing work! glad to see mr bozo stopped in at your shop, he's been at my house for weeks. everything i tried to working on was broken more and/or frozen with rust. i was checking my emails and got a phone call from a friend don't open any emails from him "i'v been hacked!!!" too late, computer crashed!!! new anit-vierus. i like the light gauge. thanks for sharing

[@StefanGotteswinter]

sam yeates O man, I have days and weeks like that too...thats not to much fun :D

[@daveprototype6079]

Definitely looking forward to part 2... Looks like I may make one for myself. Thanks, Dave

[@StefanGotteswinter]

Dave Prototype Part 2 is already down to editing :) Thanks for watching!

[@geneelliott2825]

Thanks for showing the shaper set up and action! I'm building a shaper and have just about all the casting done, looking forward to the machining process as I find the time.

[@StefanGotteswinter]

Gene Elliott Are you making the gingery shaper? Or did you design one by yourself?

[@dlstanf2]

Good job on video. First good explanation of a clapped scrapper I've seen. Thanks

[@danielwerger5641]

Again, excellent video Stefan.... I also love my shaper (Canadian Peerless), a wonderful machine tool. Built in the 40's. Still going strong in the 2000's. Not as precise as yours, but still hogs off metal. The shaper is very useful in that its very versatile... Keyways, planning, etc. Great machine. Please keep up the great video's.... Cheers, Daniel.

[@fredfarnackle5455]

That shaper sounds like the Tardis taking off!

[@niltonpolydoro1]

Hi Stefan. Very nice project. Thanks for sharing Nilton Polydoro from Brazil

[@didieryvron149]

Hi Stefan, Your project enjoyed me, so I did it similar on my milling machine (I've no shaper in my workshop). It's a very helpful item for me and an additional to the normal sine bar. I use a spreadsheet Excel to calculate sine of an angle and in return the size of block between the dolpin and the base, very confortable Regards, Didier Yvron

[@garyshirinian]

You always do great work . When Ido my square up , I do the same except I also put 1/8" wire on the base of the vise . Only when I do 2nd face , then i rest it straigh on the vise base . I guess your also works . Never tried it that way .

[@pitu72ger]

enjoyed. liked the camera work where you setting up the tool to correct angle on the shaper.

[@skiptracer8703]

Stefan I like to see you use the shaper. I learn something new with each video. I hope my atlas # 7 will run even half as good when I finish rebuilding it. Jim

[@AmateurRedneckWorkshop]

Great video. I very much appreciate that you tell us the tool speed and feed rate and other particulars. It is very helpful for us beginners to see what the skilled machinist would choose. I have a chart for these things but it always gives a range of rpm or feed and I then wonder which end of the range someone like you might choose. This looks like a great project and I will be following it to the end. Thanks for the video.

[@StefanGotteswinter]

cerberus Thank you :) I choose my speeds and feeds most of the time by my gutfeeling and some experiance with burned and broken cutters. The charts from the manufacturer work most of the time, but I tend to use the speeds/feeds of the lower end in the homeshop, to give those expensive cutters a longer live.

[@JoggingWithForks]

Excellent video as always!

[@StefanGotteswinter]

PJ Thank you!

[@billsmith5166]

That little Mitsubishi end mill is one tough dude. I was looking for my eye protection.

[@kierondesmond7791]

+Stefan Gotteswinter. You had to revert to the standard clapper box because, with the reverse clapper box, the tool/holder moved down on the return (forward) stroke causing a jam. Could you have turned the tool holder around so the tool was nearer the pivot point of the reverse clapper box? I realise you would have to lower the tool holder to make room for the tool to fit under the clapper box or use a shorter tool. Thanks for all your videos. Great learning resource.

[@sevenninthsfabmachine]

I like your hand-drawn sketch at the beginning of the video. Such a neat project. Looking forward to seeing it in action. I just got a MarTest dial test indicator (.0005") because I wanted one with an extended range (more revolutions) and also, I like how the green face is easy to read. They are very sensitive indeed! I planned to get a matching "tenths" (.0001") MarTest, but now I wonder if the spring pressure may be too light and the needle will bounce around too much. Still, they're beautiful test indicators, and from Germany at that!

[@StefanGotteswinter]

Seven/Ninths Creative Thanks! For me handsketching is part of the process, I get much more attention to the project by drawing by hand than doing it in Cad - Thinking through every little detail while drawing freehand. For me its funny with the Mahr tools - I love the dial test indicators they make but I cant stand the normal dial indicators, digital calipers and micrometers they make, even if they are realy high quality (They are in fact) - But with those tools i prefer Mitutoyo any day :)

[@aserta]

Lovely episode! And miniature blue chips :D

[@StefanGotteswinter]

aserta Seems like everybody likes blue chips :D

[@aserta]

Stefan Gotteswinter They are pretty, you have to give them that.

[@CJ_LEGAN]

Nice shaper video.

[@bobvines00]

Stefan, I don't know if you will see this comment, but I have to make it anyway. I think that your middle name is "Precision," based on your projects and skills. This is a very interesting project and I may, one day, build one too, even though my mill-drill isn't really up to the task, I think. I'll need to disassemble it and attempt to "dial it in" to be more accurate. It's a Chinese "kit" of mill-drill parts! Did you rebuild your shaper to be as accurate as it is? I look forward to watching your videos until I finally catch up to your current videos! Thank you for posting such interesting and educational videos. I learn from every one of your videos!

[@outsidescrewball]

Enjoyed, cool project

[@StefanGotteswinter]

outsidescrewball Thank you chuck, also thanks for adding me on facebook :)

[@EmmaRitson]

this is a good series.. why does it only have 27k views??

[@parkermusselman9824]

If you reversed the tool holder (and flipped the cutting tool) while still in the pull-type clapper box would that bring the tool to the other side of the pivot and allow it clearance? I hope that made sense. Thanks for all the great videos!

[@artmckay6704]

is there an advantage to using a shaper instead of a fly cutter on the mill? Thanks! :)

[@nixie2462]

Awesome. If instead of a ball bearing, a lapped cylinder was used, would it allow for a greater clamping force, while still doing the 3 point contact?

[@TheAlfieobanz]

I laughed so hard when you call your indicator "a bitch to work with"

[@bubster1981]

Whats the reason for a heavier cut in reverse? Great video

[@StefanGotteswinter]

bubster1981 The cutting forces work against the machines column and therefore everything is more stable - If I take a heavy cut on the push stroke you can actually feel the table bend down a very slight amount.

[@whyturtleracer]

Stefan, very nice as usual. Were you injured on the job?

[@StefanGotteswinter]

whyturtleracer Thanks :) No, actually at the desk with a surgical blade while cutting cardboard...running machines with sharp tools and plenty power all day long but injuring myself with a supid blade :D

[@DoRC]

any videos of the 1911 you're making?

[@StefanGotteswinter]

There are a few videos, but I consider that project discontinued.

[@FredMiller]

Great project Stefan. I am somehow relied that Mister Bozo does not only visit US shops. ;^) Looking forward to the next segment Fred

[@StefanGotteswinter]

Fred Miller He seems to be common all around the world - But until Mr. Lipton he had no name ;)

[@andyZ3500s]

He has always had a name. It's just not polite to say it

[@mikejoslin510]

What make and model of mill is it you use?

[@StefanGotteswinter]

mikejoslin510 My milling machine is an old 1927 Deckel G2 engraving machine that had its pantograph removed. I put a 40taper highspeed head on it and converted the whole machine to cnc, result is a very sturdy little almost-toolroom-milling machine :)

[@daveticehurst4191]

Hi there a great project. Now a question please, I expect everyone will laugh at me for asking but here goes. Here in the UK I am used to Imperial measurements a Sine bar is 2.5 inches or 5 inches or 10 inches centres. Look up the Sine Tables and use the appropriate Slip Gauges all works fine. Done it for 40 odd Years. Now I notice that you are making this at 60 mm centres. Does that mean that there is a Metric Sine Table Chart or even Metric Degrees ? Sounds silly I know, but I never could understand the Metric System ( Microns and all that ) perhaps someone can enlighten me or give me a link to the information. I have not done a search on the web yet, thought I would ask you as you seem to know all about Metric. A further thought about your Shaper vice, I was always taught to have the fixed jaw at 90 degrees to the cutting force and not as you use it. Your way the work could move longitudinally in the vice in the event of a large cut. Thanks, keep up the good work.

[@StefanGotteswinter]

+Dave Ticehurst I dont use sine tables, i prefer the calculator. just calculate the sinus of the desired angle and multiply it with the sine-distance. Degrees are the same in metric as in imperial :)

[@StefanGotteswinter]

+Dave Ticehurst As for the vice, I dont care to much, as the forces my little shaper exceeds are not that big. I rotate the vice that way that meets the part the best.

[@ardvarkkkkk1]

+Dave Ticehurst Forget the tables and just do the math. I didn't know that anyone still used those tables. The calculator made them obsolete. The metric system has the advantage that it can be learned in minutes. It may take a little longer to remember the units but the system is all base 10. Unlike the imperial system with it's inches, feet, yards, chains, rods, etc.

[@ardvarkkkkk1]

+Stefan Gotteswinter What? You've never heard of a millidegree? :)

[@rogercrier]

When we did time study as apprentices, there were stopwatches with one hundredths of a minute!

[@joecomunale5030]

Great Videos, and nice machining work. Will you post your plan sets somewhere? Or email them upon request? Please keep up the good work!

[@robincox8902]

No music yhaaaaaaaaaaaa 😀

[@Coffieman5150]

what in the world did you do to your thumb, ouch.

[@StefanGotteswinter]
