Sand Scorcher Crawler - Another Bug

[Tossedman]

Yeah, but if I had your engine I might be finished this build.

Mirrors and hubcaps are DOPE, and the wheel/tire combo is so perfect.

Excellent build thread!

[Tossedman]

Thanks Durok. It’s getting there.

[Brian5582]

As others have said those wheels and hubcaps make the car. Engine isn’t too shabby either

[Tossedman]

Thank you sir.

[Tossedman]

Got a little sidetracked today. I made a thing...

[M and M]

Er.. think you've missed out the oil pressure switch!!!! Seriously what a thing of beauty. Just how much more detail you can achieve, I can't think. What scale is that, if I may ask? Great work, as always Todd, thankyou.

[Tossedman]

Oh crap, you're right mate!

And thanks. It's 1/10 scale ...ish. The one on my Carisma is 1/8.66 scale ...ish. Nice thing about 3D printing is that you can scale to any size you want. I bought the file for a 1/5 scale engine and have modified as needed. Hollowed out the cylinders for this pic. Might have to hollow out a crank case as well for that stand. I'm thinking of building a garage diorama for pictures, hence the engine stand. It'll be slower than my regular build though.

Cheers Mike,

Todd

Awesome work, big fan of your last bug build as well!

[Tossedman]

Thanks Devwon.

Printed a few more bits for the bench. Now I ought to build one.

[Synister_Intent]

Amazing work! That is the most detailed scale engine I've seen. Keep up the good work.

Thanks man. I’m spending way too much time on this engine. Gotta get this bug driving. Printing a crankshaft as I write this.

Hey Tossedman!

- can I ask you a huge favor?

Can you post the measurement of the inside wheel diameter?

I am thinking these wheels in white would serve nicely as old-school rally wheels on either a Traxxas 4-tec 2.0, a Tamiya MF01X or a Tamiya Mini chassis and I am trying to figure out if they will clear the steering and suspension components.

The inner edge-to-edge distance of the back lip as shown here:

[Tossedman]

Sure, it's 1.72 in or 43.69mm. Edited to read 1.72 in. I cannot type.

[durok]

Much appreciated, my man!

Looking forward to more of your incredible build...

I swear we must be close to the point where we can print these parts in metal (which we can already) and make real scale working engines which has been done too, but for RC.

Cool! You can 3D print in metal but then you'd have to machine any places where tolerances and smoothness are important. Same way things are cast and then machined. But then is a 3D printed part strong enough? Dunno?

Yeah probably not, its basically sintered metal which isnt that great for strength. Seems like all of these videos of tiny engines have them running for very short periods probably due to heat or other limitations.

Got a new mechanic working on the engine today. New bench too.

[Tossedman]

And here's a taste of what's to come...
