When one Phillips isn’t enough. Recorded in between years as Stefan would say, Max invites his brother Thayer and his father Fred on to join in an end of year discussion with our new semi regular co-host Stefan Gotteswinter! In this episode we talk about:
- Fred’s shop that Thayer works out of. Fred has a really nice Rockwell mill (one of our all time home shop favourites) and a Southbend Heavy 13.
- We talk about gunsmithing in the United States, Germany and Canada
- Live free or die!
- CAD and Stefan’s embrace of Autodesk Fusion.
- Stefan machined some really nice Torx screws using his Deckel pantograph.
- Justin is busy making Christmas presents.
- Stefan wants to get a CNC lathe in 2018.
- Max is hoping to finish his Trent pinion mill.
- Both Max and Justin are hoping to get back to semi regular posting on Youtube.
- And finally cars. Max is hoping to get some German iron.

Many thanks to Fred and Thayer for joining in!
Many many thanks also to Stefan for coming back on and agreeing to become our third co-host! We hope to get Stefan on much more frequently in 2018. You can find his website here: http://gtwr.de/ Stefan also has one of the best machining Youtube channels: https://www.youtube.com/user/syyl.On Instagram: https://www.instagram.com/stefan_gtwr/

A final note regarding the live stream with Robin Renzetti and Stefan Gotteswinter. We are still hoping to do this in the next few weeks. Stay tuned for more announcements!

Excellent. I can’t wait to check it out. I have 24 hours of driving from TN to WY on Monday-Tuesday. I plan to listen to this one and review a bunch of your old ones on the trip.

Well it’s good news you have a long drive :). Safe travels and try not to throw anything at the radio.

Nice show, as always! Keep ’em coming! Really glad to hear Stefan is going to be a regular, you three always have nice discussions. How is that livestream with Tom and Robin coming along?

Justin,
Stefan is was excellent (as usual) and his humor is spot on, Max’s father & brother were equally good, great episode. My favorite line, (I parapharse) ” we will have to listen to the podcast to hear what was said” Don’t do that to me when I am driving you guys!

Well, you said the welders out there would scream…
Frankly, I’m always happy to hear people are learning welding! I taught it for about 7 years at Rice (which earned me beer money as an undergrad and saved me from grading papers as a grad student).
Yes, i can confirm there ARE people out there that are skilled at both welding and machining. At least one, that is… me.
I find welding to be even more of a zen state for me than machining; the world shrinks down to just the pool. Dark lenses help the experience 😉

Glad to hear that Stefan will be a more regular co-host. The three of you have a good podcast chemistry. I always laugh, and learn a lot without feeling like I am being lectured.
Regarding the use of faceplates, before milling machines became accessible and affordable to the home shop machinist, the faceplate was essential. If you read the older English books on model engineering or better yet, watch Patelo’s engine videos to see how versatile they can be.
The Rockwell mill and the Clausing 8520/8525 are my two favorite milling machines for the home shop. I would pay the asking price for either if I could find one within 200 miles. Smaller, quality milling machines seem to be more abundant in England, relatively speaking, where there was a much more active model engineering tradition.
3D solid CAD software is a bubble that is about to burst….at least on the modeling level. The whole Maker movement, and particularly the explosion of 3D printing has resulted in many examples of free or near-free open-sourced 3D solid modeling packages, though they still are not quite there yet. This is why someone like Autodesk is experimenting with offering Fusion 360 for free on a limited basis. However, I think that such products are riding the tail end of a dying wave in terms of modeling. Within the next 5 years, free, quality, easy-to-use 3D modeling software…and not just cloud based….will become ubiquitous. Where this software will remain weak is in the drawing category. Most Makers and 3D printer users don’t really care about drawings, so the demand for good drawing modules will lag. Sure, the big CAD companies will continue living off of the need for advanced CAM capabilities, and other post processing modules like FEA, but the days of charging $5000 per year for this software is coming to an end.
Speaking of German cars, I was very disappointed in VW’s new 2019 Jetta. VW has now joined the chorus of every other car maker in adopting the “creased” body design that started by the Koreans. Blech! I expect clean, unadulterated lines from the Teutonic car companies. Now it looks like every other non-descript sedan on the road. For some reason, the same treatment on the Golf does not look as bad.

I started learning metalworking (and soon specializing in machining) at trade school last fall and thus trying to fill my head with everything, mainly machining related (as that seems to be the most interesting area of metalworking for me). I’ve been now listening to few episodes of the podcast after the Robin Renzetti one, as that is how I found out about this podcast. I’m really liking the podcast, thanks for doing it! I think Stefan is great addition to the podcast hehe 😀
I get the self-deprecating attitude when it comes to tangents etc, but in my opinion, it is ok to just shoot the shit like you’d be hanging out. Not all of us have bunch of machining friends living close by that are actually that interested in the trade to be talking and learning about it on their free time.
In one episode (can’t remember which one) you asked listeners to maybe write some ideas what to ask from Robin, and now that it seems that Stefan is going to be joining as well I was thinking the following:
– If having large contact area of machine ways (a lot of those blue spots after scraping) is good for the ways (for example), why is it still scraped and not lapped to have near 100% bearing? Is it because there has to be something to hold the oil layer to not wear out the surface? Couldn’t it be lapped near 100% and then force oil to the ways through some channels, instead of lowering the bearing surface by scraping it?
(I guess the wringing effect that happens with gauge blocks would play part without proper oiling?)
Also, I’ve read some interesting articles that are related like these:
https://www.researchgate.net/publication/223695445_Microlubrication_effect_by_laser-textured_steel_surfaces
https://www.researchgate.net/publication/245389122_Effects_of_surface_texture_size_on_the_tribological_properties_of_slideways
http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0152100
that are related to machine way surface and friction and would like to hear opinions on the possible evolution of the machine way surface patterns from simple push scraping, moore pattern scraping to potentially abrasive blasted/micromachined (I guess this is kind of related to watchmaking as those people are also micromechanics having to deal with small parts) or something interesting new like that? (not sure what the heat of laser would do to the metallurgy…) I mean, with some kind of CNC scraper/micron size milling machine, one could engrave all kinds of groovy patterns to lapped surfaces to have super good bearing but with an optimized oil retaining pattern?
(I’m just thinking here as I’m not a professional machinist, just some random fella having too much time in front of the computer and too little access to bumblefucking in the shop.)
– Spindle making for Dummies/ELI5: Spindle design and resources for learning more about it. I’m interested in trying to make my own lead screw and spindle at school to learn more about machine building. Maybe even trying my luck with making something small for myself with the machines at school, to use at home. (Althought this is a crazy pipe dream at this moment lol) I’m asking this because https://www.youtube.com/watch?v=dKFffDf8Nks was very inspiring to watch for me after starting to read Sir Joseph Whitworth Measuring Machine book (from the 1800’s that talks about the three plate method) and also Moore Foundations of Mechanical Accuracy. I remember that Stefan was interested in buying a small CNC lathe so maybe this could be an interesting alternative to combine these various skills that he has? 🙂
Sorry for wall of text haha, maybe in the future not ask listeners to ask too many questions :DD
Have a good day! 🙂
