All aspects of your videos are very professional, but what is truly exceptional in yours is the pacing. You include just enough of the various operations to clearly show what you are doing, without letting it get boring. You and Tony stand out in this respect. Most others let the operations go on much, much too long. Thank you!
Stefan, Years ago when I was a young apprentice my training instructor taught me to use a piece of notebook paper for touching off. A piece half again as wide as the keyway underneath the cutter and very gently bring the cutter down until it is marking evenly. Very accurate, and fast. It works for any machine tool.
by far my favorite hobby machinist. your perfection is very nice to watch. you're philosophy about life makes me feel better too. " just have to do it. "
More super Stefan work -- that keyway tool centering is without doubt the most logical method. I've said before - oh boy do I miss my big old shaper! You keep your shop and machines so clean! Nice job.
Nice finish on that part... looks very professional. So after his shaper completely rusts away after the next great war and some aliens excavate the remains 5000 years from now, the only thing left will be your ratchet gear in perfect, spotless condition. They will wonder who was able to make such quality parts in what they will refer to as our dark ages. ;) Very nice camera angles btw. especially your famous shaper right in the eye shots... glorious and very educational. Thank you for sharing another adventure and take care!
A complete part from start to finish shown in just one segment. As others pointed out, with just enough detail to make it instructional without being boring. I have broaches for keyways but using the shaper provides superb control. The matte surface would help it retain some lubricant in other applications. Thanks for making such professional videos.
Always fun to watch your videos, Stefan. Not only are you a fine machinist, but you are a "not too shabby" video producer, too. ;-) We know if your name is on it, it is going to be quality.
Great video. Setting the height of the slit saw is a great example of why many gauge block sets have wear blocks - a size that the manufacturer makes a large batch of. You use the wear block on the end of your stack so that it takes any abuse instead of the other blocks that you keep pristine. Replacing one 0.100" block is much cheaper than replacing several odd sizes in a set.
Very professional looking part, Stefan. If someone sees that part, would definitely think it was made in a professional manufacturing machine shop. I'm always enjoying watching your videos. Keep them coming.
It is always enjoyable watching you work. You do have a good grasp of the small details which is pleasure to watch and learn from. Thank you for taking the time to show all of your work and I must say the camera work in this video is superb, love looking down the hole as the shaper was cutting the key way.
Love the grim opening music. When I have a hard interrupted cut I relieve the leading edge of (in this case) the key way, a lot easier on the tool edge. Love your videos
Love all your videos despite not having machine shop tools myself. (I've always worked in wood). I've stopped watching cable TV since channels like yours are much more enjoyable and educational. Keep them coming.
Hey Stefan. Did you know that you can use the reduction ratio of the rotary table divided by the number of divisions without needing to work out angles. i.e. 90 (rotations per rev)/30 (divisions) = 3 (hand wheel rotations). this also works for fractions. so if you want 100 divisions you get 9/10 turns (18 holes on a 20 hole dividing plate etc)
Stefan, Thank you very much for these wonderful and informative videos, thanks for the information of the files, I have seen two videos of you and I was impressed with the quality of your works. Grüße aus Chile
Very nice. I imagine the part was more accurate and finished better than the original. No one ever fubars the indexing. :) "so I don't fubar that, not that I ever did that". I enjoy your injections of humor.
Nice piece of job! 17:19 - before pressing START machining -ALWAYS have one thought behind your head: if the machined groove doesn't have to be positioned with the keyway groove inside the center hole. To be honest, once I've fu...ked up the similar to your's sprocket - the first tooth had to be rotated for 4degrees relative to the keyway. Of corse the sprocket is non symetrical then, so it is also important to notice if your sprocket is correctly placed inside the dividing tool. If there's no drawing for the toothed wheel, always ask the client for where and what it's used.
Thoroughly enjoyed that Stefan, was hoping that you would cut the teeth on the shaper but I guess I cant have everything. Thanks for the indexing explanation. I am always inspired by your workmanship and approach. Thanks for the time and effort making & editing & uploading these videos. All the best Mat (Sadly no feature of your sandels this time...)
Thanks, this is again a great video. Even if thee is no black magic, I like what you show and learn a lot every time again. I thought I had gone through your whole collection by now, but this is is still new to me 😁
2/100th of a mm Run out?! Toss the part and start over! Shotty work Stefan...Shotty work. ;) Always look forward to your videos. My only complaint is that you don't make enough of them. Looking forward to the next one.
I agree; there's something remarkably attractive about that part. Probably the combination of the bead blasted exterior, contrasted with the finish of the bore after hard turning. I've had a 14" G&E shaper since 2010; picked up a Rockford 24" HD hydraulic shaper a month ago that needs wired up. It doesn't have the ratchet feed wheel. Excellent shots of centering the keyway in the bore; I've watched your previous video on the subject multiple times. Do you ever use any other method besides "the even scratch"? Thanks again for the great video!
Cutting key ways with a file is a pain. last time I did one, I made a jig using a windshield wiper motor with a small crank arm and a file on the end of a long connecting rod. Turned it on and let it do its thing while I worked on something else. I've seen shaper attachments for bridgeports but I just don't do enough key ways to justify the price.
I have a G&E shaper, it has a broken elevating gear for the table, it is a bevel gear that has an extended side which is threaded with #6 acme threads so it looks like a mushroom. When the drive gear turns this gear is moves on the acme thread and raising the table. The acme thread is mounted in the base of the machine and it does not turn. I have not been able to find and good videos about making bevel gears as of yet. Have you ever had the occasion to make any bevel gears before?
+Chris Stephens. YES it is a Staggered Tooth Side and Face Cutter, look at it very carefully and you will see every other tooth is missing. Stefan says every other tooth is missing. Also you CAN take a side cut with this type of cutter, that is why it is called Side and Face. Stefan ran it around around a second time as he needed the slot to be 1.8 mm and the cutter was only 1.6 mm. I think you may be getting confused with a staggered tooth slitting saw, not the same beast at all.
Just looked again in higher definition, I usually watch in 240 due to slow net speed, and I concede that there does appear to be a cutting edge on the side. In low def it looked like an ordinary saw blade, I shall delete my erroneous comment.
My Wife was on the computer when the notification appeared in the bottom corner. Had me pacing up and down the room trying not to look interested until she had gone. Inspiring work again Stefan well done. Use of the word 'Fubar' made me spit out my coffee !
Stefan Great job very well explained Now a idea for a video. I have in the past made. Parallel tooth bevel gears on the mill/rt setup. But I have got consfused ,the correct way according to mr Law ,s book is you do three rotations with a plus ,normal,negative offset with a corresponding hight offset Now looking at the web all show a two stage operation If you could spare the time to explain the Stefan way including the calculation for the gear cutter selection I am sure it would help others and me The ones I have made have worked for the govener drive for a model steam engine last set was a 1 to 2 ratio so the blank angles were not 45 deg. In anticipation Stuart
Good vid Stefan. You take pride in your work in every video. Now, brass tax: Why does your TEFC lathe motor have the centrifugal fan cover exposed to coolant and swarf in the back ( lower chip guard). Is that an after thought guard? It should have protection...no? Please keep making vids, learned a lot from you.
Nice work as usual. You probably thought about how widening the teeth cuts by changing the cutter height produces a different geometry than widening by slightly changing the angle. How did you decide which method to use?
Wacken, hope you seen a few great shows there, could think of a few heavy shows i would love to see there... cool, love all of your videos, extremely entertaining, loved you the characters from This Old Tony... from Louisiana, USA
