That thing, among others. To me, this was the easiest part to weld and we came up short. So what's going on behind the scenes. Also see how it's all super smooth? That's from running over an existing weld, which isn't ideal.

not shitting on this guys parts. Just helping others. A back handed learning experience.

I just looked at the pics again..it looks like 2 different people worked on it. Some looks really good, then other sports are less than.

Yes completely true. The welding isnt the nicest one. Ive made a closeup and inspected and there is no hole. Its just not looking good. Its all made out of 3mm thick tubing.

But im still happy how it all turned out.

oh in btw. Its equal length and tested with flow simulation. This was the shortest path of tubing i could make for this twinscroll design

https://cimg2.ibsrv.net/gimg/www.mia...5cfc36f03c.jpg

Hey bro, your design work is awesome. No blame on you at all.

Definitely. The twinscroll crew is pretty lean. I'll be hoping for a dyno in the future. :naughty:

Checking in from the twin scroll crew. Still undecided on 6758 or 7163 though.

You should do the 7163. I can take care of the back to back t2/twin scroll comparison and it's on the same engine.

Superhead is sold. I will be running the same vvt head I have, just refreshed

kinda happy about that I really want the 7163 but dont want to have too much turbo. Like there is such a thing haha

I was getting used to the car at 430hp on the 6758 before I pulled the head.

No such thing as too much turbo until you boys start eyeing the 9180's :D

Here are some extra pics, Originally it was design to have milled collectors. Im running a MR-2 powersteering pump, and hope it still clears to steering axle to the steering wheel or how is it called.

And i friend of mine asked if he could have it 3D printed at school. Wich i didnt have a problem with:D

That's quite interesting. How did you produce the 3D model of the engine and subframe?

These models are made with 3D photogrammetery, but i also have 3D models made from scratch of the MX-5 but those are not exactly the correct size

You can see some of my work on the IL Motorsport youtube site like this movie

Go full YOLO and have that plastic mold turned into a cast stainless manifold. I'd like that for a 1.6 for under $500 please.

I built a thing that does stuff! (Not even remotely car-related)

https://cimg9.ibsrv.net/gimg/www.mia...9d7c2c020a.png

Nice thing! I'm curious what stuff it can do. Can it try to take over the world? :brain:

Me, too. We'll find out in a few hours once it's mounted on the robot.

I :heart: machined aluminum look, but upper management does not. Many people think our parts are cast because of the tumble process we perform. Oh well.

I did these a while ago but never posted them here. As things go, this CAM software doesn't work with the ever progressing solidworks so i can't do fun stuff like this as easily. Damn software licenses.

That's so pretty, I almost wish you'd o-ringed the top with a thick piece of lexan just to see what's underneath!

That was considered at one point. Then life happened; I only drove it once this past summer. Miata is currently underneath 3 feet of patio cushions and a grand wagoneer hood. The car will stay at 98% done for as long as I own it.

Can a car ever really be done though. There is always something more you want to do.

Up until about a year ago my answer would have been:
No. Yes.

Now, and for a long time from now:
Yes. No

I am starting to understand what it is you're saying.

Unfortunately, my car is at 50%, and that has become my attitude. I'm officially an old fart.

I had some time to testfit the manifold with the turbo and i think it looks pretty good.

Totally serious question: how much Bondo is in that picture, just below the very pretty white paint?

What purple is that?

Spray foam, file, then bondo?

Instantly thought of you when I saw the purple.

What caught my eye was the intake manifold.

Not that much, before the bondo was aplied i made it as smooth as possible

I dont know exactly what color purple it is. Its not a RAL color

That's the weird thing about being "too pretty."

When it's a woman, you can assume that they are going to be high maintenance and probably have some self-esteem issues.

When it's a car, you can assume that you're looking at an ocean of body-filler.

what the F is thaat intake manifold?

Also one of my designs. Welded by someone else

Read your thread.... appears to be a Skunk2 with a large custom plenum? I can dig it. :)

Buildin' more stuff.

Some of it is being done the hard way:

https://cimg9.ibsrv.net/gimg/www.mia...2601a64c35.png


And some the easy way:

https://cimg9.ibsrv.net/gimg/www.mia...a2937389c1.png



I have to admit, the hard way and the easy way are both fun in different ways, distinguished mostly by how many of a certain part needs to be made.

More than 2-3, and I usually go the easy way.

Joe, you need a decent 3d printer. I am constantly surprised at how may tools and parts I can make with plastic. 9/10 they do exactly what the metal part would have.

We did recently buy one at work. But this is a part I wouldn't 3d print. It has threaded holes, and is going to carry about $25,000 worth of camera & lens, total payload weight of around 45 lbs, atop a moving robot. Times nine.

It's a better-made version of this piece here:

https://cimg5.ibsrv.net/gimg/www.mia...7ab2a6f51b.png

Emachineshop.com rocks it as usual. New column-locking plates for about $300 (total) per pedestal, vs $7,000 each for factory rebuilds. These 35 year old peds still have spunk left in them.

Not sure if I'm making this more complex than it needs to be:

https://cimg3.ibsrv.net/gimg/www.mia...cb9f65d120.png

Printed afm delete pipe for 1.6 airbox, testing before turbo. Designed on 360 fusion and printed with a tevo tornado using petg.

Sure looks like it to me.

Beautiful!

Not sure I ever posted this here but last year I made this.

Mount for 14" Spal on TSE radiator. It holds a 0.7" gap from the fins which I closed up with adhesive "D" shaped rubber seal.

Creating the basic dimensions that would hold the fan
https://cimg3.ibsrv.net/gimg/www.mia...c7072141fb.jpg








Had to then measure out and roughly model the TSE radiator
https://cimg5.ibsrv.net/gimg/www.mia...6499738c39.jpg
https://cimg7.ibsrv.net/gimg/www.mia...b583e2a839.jpg





Made the brackets that would hold the mount on; Fusion360 has a mobile app to view projects. The bottom holes are slotted in multiple directions just to account for manufacturing variations or if anyone wanted to use it on another radiator

https://cimg8.ibsrv.net/gimg/www.mia...e44ef9be14.jpg

That's some beautiful metal.

I love the fact that we live in an era in which I can draw a complex thing on a computer screen, pay some money, and be holding a physical manifestation of that thing a few days later.

Any plans to seal the fan against the core?

Yes! After the mockup, that 0.7" gap is taken up by an adhesive backed "D" shaped rubber seal. I made sure to acetone wipe and plasma treat the surface of aluminum to promote better adhesion :rofl:

Fusion 360 kicks butt. 99% of solid works, for free.

It occurred to me today as I was measuring an aluminum box that I have seen pictures of this rule posted hundreds of times:

https://cimg1.ibsrv.net/gimg/www.mia...45c853e097.png

I don't mean rules similar to it, I mean this exact, specific, Westcott brand 18" stainless steel rule with a crappy cork backing that disintegrates after just a few decades. It seems as though every single fabrication-nerd on earth has one.

In fact, it occurs to me that I have three of them. One which I bought many years ago, one which was sitting in my new desk when I started working at WPIX in 2013 (and subsequently took with me when I left), and one which, similarly, was sitting on a shelf in my new office at WGN when I moved here in 2016.

Is it just me? Do I naturally attract this ruler?

Got another one of these welded up for a guy doing a v8 swap.

https://cimg9.ibsrv.net/gimg/www.mia...a4c492ce35.jpg
https://cimg0.ibsrv.net/gimg/www.mia...1aaa6dc945.jpg

I need one of these.

PM me. I have materials to make 2 more at the moment and enough laser cut plates to make another dozen or so.

Could just be you, because i really like mine. Thin and flexible. Easy to get into tight and small spaces. I have many of these and they're randomly laying around.

https://cimg1.ibsrv.net/gimg/www.mia...8f38957e1c.jpg

Edit, er yeah. I measure a lot in thousands.

I have one of those westscott 18" ones on my desk at work. I used it like twice before I had the tool crib order me a proper (if SPI) 12" scale with markings in 1/16th, 32nds, and 50 thou. The westscott just sucks because it isnt very straight on the edge,the corners are rounded, and the zero isnt on the end and for like $25 you can get a proper hardish scale.

I hate when the zero isn't on the end. I see why they do it, but I want to be able to measure accurately from an inside corner.

So I'm strolling through the front office this morning doing the coffee thing.

I spot this on our secretary / order entry lady's desk.

https://cimg8.ibsrv.net/gimg/www.mia...3cc2e33703.jpg


This actually really bothers me. How is this even usable?

Even the cheap HF scale I have starts at the edge...

https://cimg0.ibsrv.net/gimg/www.mia...81d2ffd86b.jpg

Because its a ruler, and not a scale. It's made for paper. Betting there's cork on the back of it, too. Still good for smacking people/children with, though.

I have at least a dozen scales at work and home. Some in tenths, some in 1/16's. Several are Westcott with the cork on the back. A couple are wooden, including an old triangular drafting scale that I can't bear to throw out, but never use.

I mostly use 6" scales, and have them stashed all over the shop. Then there are the tape measures, calipers, carpenter squares, verniers...

I work for a startup orthopedic device company. I've been trying to find a cost-effective way for our sales people to demo our products, so I went in on 3d printing. Bought a Lulzbot Taz 6 (this was definitely not the cost-effective part). It is an awesome piece of machinery though.

https://cimg8.ibsrv.net/gimg/www.mia...334eaa5bad.jpg

It's been 20 years since I've done solid modeling, but I got Fusion 360 and learned it pretty quick. Got a solid reconstruction of a CT scan, then designed these articulated demo models.

https://cimg2.ibsrv.net/gimg/www.mia...ee82008c2d.jpg

Our product is the stretchy little artificial ligament. The model is very effective.

When the printer is not being used for models, I'm making other cool stuff. This bracket to keep my stupid dog from getting into the trash can:

I fully support upgrading your setup to include a box with filtered exhaust fan to keep the stink down. Also fully support getting a raspberry pi and running octoprint on it. with a webcam. it's incredibly handy. you can manage it remotely and even via phone app.



https://lh3.googleusercontent.com/cZ...=w882-h1175-no


app with live webcam:

https://lh3.googleusercontent.com/WZ...=w588-h1175-no


and yes, those are gas/vapor mask cartridges. they are cheap and do a great job.
my next upgrade change is to have the raspberry pi manage the fan and lights so I don't have to hit a switch to turn them on when I start heating the nozzle / bed.

Wow. That, sir, is a fine setup. Did you build the box yourself or is that a kit?

I just started messing with Arduinos a few months ago, I probably need to get the Raspberry Pi thing figured out too. My programming game is weak.

I did build the box myself. It's mostly from McMaster-Carr. the sides are PETG.

The nice thing about using Octoprint with the Pi is that you don't need to program anything. Just follow the instructions.
https://octoprint.org/download/

There are a few linux commands to type in and a couple of files to edit, but it's pretty easy. All you need is a PC with an SD card reader to get started. The rest of it is GUI. You can then connect Octoprint to Cura and it'll show the live video, controls, and temps right in the Cura UI.
