Carbon Fibre 3.5mm

Post by Sarky1 » Tue Sep 02, 2014 4:26 pm

I cut some Carbon Fibre this weekend (Yes I know the health Implications and took the required safety precautions)

Look how nice this motor mount came out using a fully stock Shapeoko 2. Very impressed.

This is off the machine, no sanding.

Wow, looks very nice! I'm learning to fly some RC helicopters on my spare time. I'm a total newbie but it's fun lol. How are you liking your Shapeoko?

looks nice. Can you please post your feed, speed, stepdown, bit size, etc?

Why carbon instead of G10?

Very nice indeed.
Where do you buy carbon fibre stuff?
Is it very expensive?

That mounting plate looks killer. Very nicely done.

Where did you purchase the carbon fiber sheet from if you don't mind me asking? I'm prototyping some parts for r/c pan cars for oval racing and the final product would be carbon fiber sheet. The problem is the best pricing I'm finding is upwards of $100+ for the size sheet I need which blows the target budget for the finished product.

Thanks.

Have you tried eBay?
Search "real carbon fiber panel" and then weed through the vinyl wraps and trim stickers. That is where I found the carbon fiber panel I used for my end pates and coaster sets.

Thanks for the comments.

I actually ordered through these guys as I have seen their sheets first hand.

This stuff is unbelievably strong even at 500mm I can't flex it.

As for Carbon Fibre over G10. No real reason but I love the look of Carbon fibre. I realize the RF properties of carbon is not as nice as G10 but that's not really going to be an issue in my setup.

I fly professionally and my main reason for the Shapeoko purchase was to be able to cut my own designs. So far I'm very impressed. I will be cutting the frame over the next week.

Here's the info for this cut. I'm happy with the product and I will continue to use these settings.

Feed = 300mm / minute
Plunge = 150mm / minute
Spindal = Stock shapeoko demel knock off at max
Stepdown = 1mm
Bit size = 1.5875 (0.0625 inches)
These are the bits I'm currently using

If you're on a budget I would suggest G10 FR4 instead, it is much less expensive but almost as strong. Carbon looks cool sure, but I'm not willing to pay the premium, as it's just not necessary in most cases. Not to mention the health hazards when cutting carbon (gotta cut it underwater, or make sure all the dust is well contained). Also G10 is mostly RF transparent (not 100%), carbon is not and can do some nasty things to your radio signal. Sorry, that kinda sounded like a soap box, wasn't meant to.

I use http://www.eplastics.com for my G10. Their shipping is kinda pricey but stays mostly flat as you add more to your order. I will be cutting some FPV micro-quad frames soon, as well as a 700mm gimbaled camera ship from G10. A buddy and I are working on the designs, both are not really like anything out there right now.

Just a FYI for G10, it is also hazardous like carbon fiber you must be using a respirator + vacuum with a very fine filter in it, and a well ventilated area.

Nice! Thanks for posting the speeds. Those settings are more aggressive then I would have guessed for such a small end mill, hard material and stock machine.
