Projects A Kid, A Banger, and a bunch of 3D Printing.

Betcha' made some little feets happy...

 

Wonderful use of technology @Retson the Racer...

The world of 3D is very interesting...

 

Thank you! I'm hoping to find someone that can help me on a project. I'm working on this head, but for the life of me can't figure out how to create a combustion chamber.

 

Awesome use of tech. I had some Bud Vases 3D printed in plastic but would like them made them in metal. How did you learn all of this tech stuff-besides being born with it implanted in your young head? If it something an old geezer like me learn? How much does it cost to get into metal 3D printing?

i think it is called fly cut and domed ?

 

Reston

my thought for workflow.
you might use an original head and fill the combustion chamber with "clay" to get the shape of the combustion chamber.
use that clay to scan and create a solid that can be subtracted from your head model



I'm not fully versed in fusion as I taught Autodesk inventor for years before moving to another solution, however in other software they call this a BOOLEAN?

 

Loving your work Reston, looking at a mag side mount myself, I’m old so fabbing one is more in my thoughts as not many choices on aftermarket down here.
As for the shaft , my thoughts were cutting the snout off an old A crank , machining the area in front of the crank gear for a bearing ,same just behind the gear area behind the shoulder for the rear bearing allowing also for a smaller coupling diameter.
Just my dinosaur thoughts.

 

He’s printing in plastic and then investment casting in Aluminum.

3D printing in metal is extremely expensive equipment wise as the 3D printing is done in a powder bed with a computer driven laser.

At a AWS/Fabtech welding and metal fabrication and forming trade show I attended in Chicago I saw a turbine impeller blade being 3D printed with a wire feed laser on a Trumpf printer.

I was told that they can now print metal parts that are forged quality.

This 3D metal printing stuff is huge $ and not something that the average hobby guy will be playing with at this time.

 

Cool **** man. I’ve been really excited to see how new tech like 3D printing can support and enrich old tech. Maybe one day my banger will sport some Retson speed equipment!

 

Ultra cool stuff!

 

There's a process called WAAM which looks like it's got a lot of potential.

 

That's a great idea! I've also considered using some sort of silicone or something similar.

I reckon you are correct about Boolean!

That seems like it may work! I know the SM unit I have, the bearings are pressed into the housing itself. I just haven't taken it fully apart to check it all out just yet.

Isn't it crazy?! If you have instagram, check me out! I run @bangersmodified on there. Most of my parts and stuff get posted there!

Thank you sir!

Another cool process is using a filament called Ultrafuse 316L. With a few hotend and extruder modifications, you can use it on most printers. I believe you send the part once printed in this filament to Ultrafuse, they debind and sinter it (burning the small percentage of plasting out), and then send it back to you. While it would be cool for one off parts, I'm curious what it would take to do a production level of that stuff. It's about $500 for 3kg of it.

 

There may be a market for Flathead Caddy parts too. Worth exploring!

 

Many years ago while still in the machinists trade, we used a product called "Facsimile" to copy a shape.
It worked great for obtaining a "negative" without the problem of shrinkage.
Easy to use.

Here are a few sources

Travers has a few kits

McMaster-Carr has a selection too.

BTW, it's great to see a "kid" doing great things !

 

@Retson the Racer I have nothing to add that hasn't already been said, very neat stuff and great to see a younger fellow getting into parts production.

FYI, that's my favorite beer. Do they sell Nordeast in California? I always pick mine up in my travels to Iowa or South Dakota.

 

Always exciting to get new pieces back from the foundry!

 

Can you explain the ceramic coating process? Do you do it or does the foundry? Is it then a reusable mold or sacrificial? Oh, and what type of aluminum are you casting with?

 

Nordeast? I didn't know they had that in Californy.

Nice work on your stuff!

 

Outstanding. Thanks. Temp sender in the water neck is a great idea.

 

Nice work.
Will those cam covers be available to purchase?
