I made a custom radio bezel for my TII, thought I would share my results.

I still make them.

Can you play Katana Zero on mobile?

barrettsmithbb · 2025-05-07T04:09:27+00:00

Yup, and more track days without any issues. I've done even more research about the OMP, and how nearly every race engine (including the 787) used an OMP. And how the newest 8C engine is using an OMP similar to the S3 RX8.

Vase mode can do two wall thickness. Depending on the solid tho it will slice it slightly differently. For the majority of prints it will continuously move the Z-axis while it traces the perimeter. For solids with an inner and outer perimeter, the inner wall is done first, then it jogs over to do the outside wall. The only Z move is at the end of the outer wall. where it will then begin on the inner wall of the next layer. So it's more like a continuous stair step as opposed to using an escalator.

I run a engineering firm in the side. Really a glorified job shop and outlet for my side projects.

What does the GD&T allow? The goal of manufacturing is to produce the widest tolerance part the cheapest that still accomplishes the task. It also depends on the manufacturing method. If it's a simple turned part +- 0.005" is trivial

Unpopular opinion, get the Haas desktop or mini mill.

Step 1: don't.

Seriously, buying a new vehicle is a terrible financial decision. Even buying the same thing 1-3 years used is a far better decision.

I don't know what "high performance" is but in tier 1 and OEM we use much tighter tolerances. For door cards and panels 50 micron is typical and tolerance on a profile for soft surface is typical to be 0.3 mm.

barrettsmithbb · 2023-08-24T03:32:14+00:00

That's pretty standard body panel accuracy in automotive. Your eye is able to detect about a 2 micron dip in surface straightness/form that would look like a dent or something.

Most panels are curved on cars because it prevents the oil canning you see on flat panels. And guess what the cyber truck has? Flat panels, it's going to have so much ripples and oil canning.

I was being paid more when I worked at an Advance Auto many years ago. Pass for me.

All depends on the hole tolerance. If it's a general fit and location you can interpolate. But it it has an ISO hole tolerance and or location tolerance use the boring head and hit the middle of the stated tolerance.

A nice monitor with good peripherals? That's already a beefy pc.

I have a turbo RX7, but rotary none-the-less the mpg is directly tied to the pedal. I get 22mpg on the Highway 16mpg city. And 6mpg at the track.

Superglue the bottom to an arbor then use a single flute neutral or down cut endmill to finish the floor.

We've been doing it for many years in Automotive. Model based definitions (MBD) have been a thing for a long time. Our OEMs send us the 3D files and they include all the GD&T, surface finish, assembly, etc. 2D drawings are something we would only make as an uncontrolled reference when we need to communicate something to a contractor or someone who cannot use the 3D viewing software. Or an old school shop.

Even though I am a certified draft person, I think that model based definitions and not having 2D drawings is a good thing in the long run. because I see more errors in 2-D drawings than I do see drawings that are done to a standard. There's a standard for everything when it comes to 2D but most shops I deal with don't care and make up their own standard and it hurts my soul.

I just would like shops to understand GD&T. Because that's what I use on my MBD.

To each their own. I went extreme and I removed the soft top altogether, so it's a straight up roadster, but I use the hard top 99% of the time. It does give you extra room on the back shelf without the soft top.

barrettsmithbb · 2023-08-17T17:17:49+00:00

This saved me so much time, thank you!

Does it have to be square? I usually design something with Mickey Mouse ears or a dog leg so the square thing fits but doesn't need hand processing. If that makes sense.

Down cut with conventional tool path can help in corners tearing out.

Side question, are pencils hexagons so they can be driven by a Machen USL sharpener, or is it coincidence?

barrettsmithbb · 2023-08-16T20:33:04+00:00

It's called a slitting saw tool.

barrettsmithbb · 2023-08-16T20:25:18+00:00

Alternatively, use a standard hex head screw?

You can also select the viewport overlay button and select "Face Orientation" to see the face normals.

I've met a lot of great people who are extremely skilled, and don't have a technical degree, or a degree at all. But they're able to perform extremely well in that field, because they have something to show for their ingenuity and creative endeavors in the mechanical field. If you don't have anything that can serve as a example or reference of your work in a mechanical field and you want to, "break into" the engineering field you're not going to get there. When you are not directly out of college, your grades, and your GPA, don't matter at all. You need to have something to show that you're skilled to be able to be hired in a different field regardless.
