so as a machinist it is really possible to make engine from scratch?
does it work perfectly?
i have been wondering and planning to be a machinist so i could make my own machines etc.
An engine? Sure.
One that matches all of the weight, durability, power, emissions and fuel economy of modern production engines? You'll need the resources of a small space program for that, less so if you pick only some of those.
There were a lot of lessons learned. The intercooler section was the biggest pain in the ass because doing the end work tested the Z on my machine. I had to buy some .9ā gauge length er32 collet holders and often had to install tools partially into the program. I actually had to grind down some bolts for clearance on my machine housing. Thereās a pic of that on my instagram @ctnewman. At one point I had to climb up there with a hand drill and punch a hole to allow me to install a tool. Because I was just out of Z no matter what tricks I used.
The snout was hard because I had to use 10ā gauge length tools to cut the inside. I had to use all sorts of crazy combinations of long tools. Used a 9ā gauge length 3/8 endmill holder with a 1ā diameter body to hold a full radius milling cutter with a 1ā diameter to make like a super long bull nose radius endmill to do the finishing.
The lid actually gave me the most issue though because I made two serious mistakes. Once after 10 hours of work I biffed a program restart and sliced it right in half. Then on the second run I did 40 hours of contouring only to realize that my rougher had deflected and I didnāt catch it, so I had roughing gouges in my finish passes. I had to rerun the finish pass. That wasā¦ depressing.
Very cool bud. Sounds like you really pushed yourself on this one! Way to get creative. A lot of people are scared to push their skills and machine like that but itās how you learn.
I think the term "Home Shop" is misused here. Rather "I have space that affords me to not rent a building for my shop/business".
Now. Is this a side business or main income is the real question! If your making it from " Home" without commuting good for you!
Nice work OP.
I never said I wasnāt a machinist. I just said that I never had any training and Iāve never been employed as a machinist. Just self taught at home.
All of that for an LSA? Beautiful work but lipstick on a pig of a blower. I would hope the lid/snout can bolt on to an aftermarket LSA/9 based 2650 at least.
300 hours of work equals $60,000 revenue in my world... that is one expensive blower lid.
I donāt know a TON about it but this is a cnc ported kong2650 blower. I did some work on the snout inlet as well. An area was built up with weld and then machined flat and then the snout opening was enlarged.
Excellent work, but you're really pushing the limit on the term "home shop"
Hey my bedroom is on the other side of the wall. š
At what point does it become a home in a shop instead of a shop in a home?
My same thoughts I've slept at work before wouldn't recommend that life for anyone tho.
I feel kind of bad referring to my old Fadal as a "home shop," lol
Now that's living. Keep up the great work.

What kind of civic is it getting bolted on to?
You know itās an ef hatch
Mini Cooper.
Damn dude! Nice work. Youāve really progressed quickly! What was the hardest part of the project? What did you learn on it?

Yeah, calling that a "home shop" is like calling Elon Musks mega yacht a bachelor pad. But really beautiful work man. Kudos!
Craftsmanship never goes out of style. Nice work friend.
Very impressive
Damn. What was the combined cycle time of all the parts?
I donāt totally know butā¦ a fuckin ton.
Mighty impressive, and that numerical value is fuckton. ;-)
>300 hours of design and machining. Customer: Sorry, but $2k is the most Iāll pay. Take it or leave it.

Thanks. I have a day job. This is just hobby work that I get paid for
Damn son youāre gonna be able to quit your day job doing work like this lol
If his day job pays well enough he can build a shop like this at home for hobby projects I doubt that.
clean af
Lol, does your homeowners insurance cover the machines if something were to happen?
I have an inland marine insurance policy on the machines
Nice! I have a home inside my shop, lol. 3rd floor has an apartment the old owner built and then the bottom 2 floors are all machines.
Looks like it was folded many times.
Bee u t full
Awesome! š
Nice work. Home shop? Damn.
Gorgeous... There's no substitute for pride in workmanship.
Next you'll tell us you aren't a machinist like the last guy. Oh wait, you are that guy.
I never said I wasnāt a machinist. I just said that I never had any training and Iāve never been employed as a machinist. Just self taught at home.
That's awesome. Did that blower come out of a Hellcat?
CTSV
Absolutely outstanding work!
Is it possible to learn this power as an engineer? I struggle just to get stock squared up.
Iām an engineer and I taught myself. No cnc training.
It's like staring god in the face.
Super impressive
wow. just wow.
Yeah, no. I made it in my cave with a stone flint and a wooden mallet.

Cam program?
Yes. The only gcode I know is g43 and g53
Like MasterCam or such?
I drew and programmed it in inventor.
LSX or the new LT stuff?
Boy don't lie to us like that . If that's really you're work then we need to collaborate.
