Hardcore Aluminum milling on an S3

“Those who live in glass houses shouldn’t …… …….”

I had originally wanted to post in @3DGG BEST vfd settings thread but it was locked. Maybe @WillAdams can help clean up this thread a bit?

Back to billet!

Top is my designed velocity stack inlet, bottom is Jenvey Dynamics. We are both using the same inlet radius but mine should outperform them in an enclosed plenum.

So many aftermarket manufacturers get this math wrong. Bigger is not better, power is a tango between pressure/velocity and how you allow the engine to breathe. There is always give and take…but too many leave efficiency on the table. Just like a benchtop cnc, balance is the holy grail.

Some people mask issues by turning the boost up. My reason for living is to extract as much potential from things as possible. If you want to be among the best you need to think in thousandths, in the last few percents of a percent.

Jenvey also wasted flow potential on the cast flange/runners. My customer paid thousands for that assembly. It going to hurt me to tell him its not perfect.

What an amazing world we live in to be able to compete with these machines. Technology is the great equalizer and anything is possible…I just need more amps!

Yeah, I’m not throwing stones and I may have contributed here but it has moved far from a project gallery thread, but I’m suggesting something to address the issue instead of continuing in this direction so @Vince.Fab can continue showing his marvelous workpieces.

I appreciate every response and I’m just as guilty of derailing the gallery train lol. There are no hard feelings here

Just realized I never showed that latest 3d transition welded and installed. These details make the build…it has to have at least 40 one off machined pieces

Drag CRX finally running. The cam sensor bracket is working great!

Oh man, I love that sound!

Any chance we can hear it in full song?

Oh yeah, glad the sensor bracket worked out well!

Beautiful work, as always.

Hope the new shop is air conditioned and has a dehumidifier too! Houston summers can be…tough.

Maybe we should start a thread about the mistakes.
“The Scrap Bin”

What I didn’t show was the other piece that didn’t pass go and collect $200. Usually I’ll make at least double because there is always something new to learn and these machines have such a small range of forgiveness. This time a different geometry flute didn’t cut as efficient and I should have minimized the ramp diameter. The m6x1 hole became too oversized to threadmill and produce a quality thread.

Imo I scored 50% on this test but with one good part im still on the right path. Being able to weld the bad hole and rerun the part is good experience in part setup and soft cutting.

It’s ok to fail, in fact I reccomend it. But make sure to set yourself up for success no matter what. Next time you’ll do better.

Also I lived in Puerto Rico and fabricated in an open air shop. Before that in Phoenix in an open air shop. Heat and humidity doesn’t bother me, tough environments fuel the fire. :slightly_smiling_face:

Three desktop machines (but mostly s3)
Seven custom cnc pieces
Nine straight threadmilled holes
Three 1/8 tapered NPT threadmilled holes
And more melting than I’ve done in awhile.

This one really pushed a few of my limits but perseverance overcomes all. Can’t wait to see what it does on the dyno.

Plus a billet brace to make a strrooooong “V”…but that’s tomorrow’s work. Man its crazy how this year is flying past…wish it wasn’t 93 degrees in the shop still.

Decided to add a little Mothers polish by hand to help protect the surface. Kicking myself for not spiraling after the initial morph.

Wow certainly a unique gift from uncle Vince.

Gotta use the CNC to get the “cool uncle” badge! Actually was thinking of making it the top to a nice box, kids always need places to put things right?

@Vince.Fab wonderful work as always. Kinda lost track of your struggles with setting the 60k spindle up but I’m seeing more and more videos of you using it, so what fixed the issue for you? Is it cutting as reliably as you’d want it to? Also, did you actually use it with 1/4" end mills? I think that all the vids you posted so far were with 1/8?
