No One sells this VW Mystery Tool!

These old Portatool round bits are hard to find, so we made our own! The goal is to successfully thrust cut our old cases but we're missing a part, so we make that too. No one ever said #HardTimesEngineBuilding would be easy.

I really enjoy your videos, I'm a little behind you on my knowledge both vw and lathe, so thanks.

[@HapticGarage]

Glad to have you with us @harleycruiser4331 thanks for watching!

[@backyardkombi5466]

Really nice video Brent. More of this please.

[@HapticGarage]

Thanks Greg, more on the way!

[@VWJawbreaker]

What a fantastic video!

[@HapticGarage]

Thanks Gary!

[@garymucher4082]

Interesting ideas for sure. I enjoy new ideas and watching them work. Thumbs Up!

[@HapticGarage]

Thanks Gary! I feel lucky that circumstances allowed this to work; starting to understand why VW liked this soft magnesium for its machinability. Now we can keep moving forward with other challenges. Thanks for watching!

Awesome stuff. I love this kind of garage discovery. Making do with the tools and know how we have, and learning new skills along the way. Keep up the great work. I like your train of thought on the thrust cut. Cutting away less and then customizing the bearing. Makes sense to me. Just wish I also had the tools to do it!

[@HapticGarage]

Oh Annie, you would love an engine lathe. Not that I want to put ideas in your head, but they pop up on Craigslist and Marketplace. Just sayin. Anyway, thanks for the kudos and continued good luck on Helen!

[@bradleycowell4090]

Your videos are so educational unfortunately I wouldn't dare to try that but it's awesome watching you make things happen

[@HapticGarage]

Thanks Bradley, I'm sure you could do it if you really wanted to- my secret sauce is being willing to fail! Thanks for the encouragement, it's good hearing from you.

[@2GuysandaBug]

Great video, love how you just do it and enjoy the process. Keep these videos coming :)

[@HapticGarage]

Thanks Guys, you said it well. More on the way!

Your machining skills are looking pretty GOOD ---- the round bar stock in the lathe --- the distance -- across -- the end -- as you called --- Width --- is called -- Diameter ------ Width would be used in Flat Bar Stock ------ I like your idea of -- ONLY -- removing the bare minimum ----- Well Done ---- And Thank You for the Video ----- Rodney

[@HapticGarage]

Thanks Rodney, they say the best way to learn is to have a project... we definitely have that. More on the way!

Rocky Jennings from WALLA WALLA Washington sells and makes all kinds of tooling and engine work

[@bigears4014]

You cut minimum on the case and then turn the over size thrust bearing on a lathe to suit the case

[@HapticGarage]

Indeed, the preferred way to do it. Saves case life and avoids expensive mistakes!

Use t small cutter tool holder without bit for spacer

[@mikemakuh5319]

You got a lathe, why don't you rebush the end holders?

[@HapticGarage]

Hey Mike! Yup, that was an option we may still end up doing. But... We started by making new bushings: ua-cam.com/video/JCO-k3RTGlw/v-deo.html

[@Treacherous_One]

what about spring loading the cutter? put a collar behind the cutting tool with a heavy spring in between to keep the pressure uniform.
EDIT: I mean spring load the rod on the bushing you are using to set the cut depth.

[@HapticGarage]

Hi Treacherous_One, I think that would work similarly to hand pressure with the advantage of consistency as you mentioned. It would still require small limited cuts because there would be nothing to prevent the cutter from grabbing the soft metal. A consistent feed rate would be kind of tricky but might be possible by mounting the hydraulic feed on the other end of the case. My guess is that it's not necessary if the cutter and depth are reasonable. Thanks for watching!

[@Treacherous_One]

@@HapticGarage I think going hydraulic could potentially be problematic. the reason being that it would be really easy to apply to much force without realizing it. Using a spring to apply even pressure even if you are only cutting a few thousandths at a time, could eliminate the chatter and the need for applying pressure to the shaft. I hope I'm explaining this right. I see it in my head and it makes perfect sense. but I might not be communicating it effectively.

[@HapticGarage]

No worries, I think I understand your idea. I'll see how the next case works out and then go from there. Thanks for watching!
