Aluminum Footboards

Postby Mobius » Sun Feb 25, 2018 3:57 am

Haven't posted much work lately, truth is I haven't made much worth posting. But this latest project was a grueling 12 hours on the CNC, with me hunched over it with a squirt bottle and a air line the whole time.

Renderings were done with Fusion360, but the vectors and toolpaths were made using V-carve Pro.

Artwork isn't mine, it was drawn up for the customer by a local sign shop. They will be footboards for a motorcycle of some sort.

Thanks for the positive comments guys.

Yah, not really my style either, but I assume the graphics have some sort of meaning for the owner.

Those are kick-butt! I'm going to be adding lots of pieces to the old GoldWing when I trike it this summer (getting old but never want to quit riding!) so any info on bits, feeds and speeds will be appreciated! They look amazing!

Nice work, for sure I wouldn't have the patience to do something like that.

Great job! I'd love to have a set of these with a different design on my scoot.

Very very nice work. He should have a blast with those. Sorry, I had to say it.

How did you get the fins, that appear to be below the surface, so crisp & clean? Some sort of very small Dremel, or.......?

She, actually lol.

2 tools were used for the design. I used a 1/8" 2 flute HSS bit to hog out the larger areas. A 1/32" tapered ballnose did all the areas the 1/8" couldn't reach, including the 2nd layer of pockets inside the larger pockets.

Wow! I'd be afraid of breaking the bit! What kind of speeds are we talking about here Connor?

I did break three of them, although 2 were my fault for trying to push them a little too far, and one was because I started daydreaming. Didn't make any money on that job :?

Ran that 1/32" BN at 23k RPM, 0.198" DOC and 25IPM. Trial an error, that is the ragged edge limit of my particular machine with that tool. Tried to go a little faster: broken bit. Tried to go a little deeper: broken bit.

I also had to keep the bit flooded with cutting fluid the entire time, or it would gall in a heartbeat (broken bit, lol).

Much appreciated feedback Connor! I'm starting to get a better understanding of speeds/feeds but always looking to learn more. And at the price of bits, I'd rather err on the side of caution! Hope to try some scrap pieces just to see what happens. How do you deal with coolant runoff? Any kind of trough or dams in place?

I used a squirt bottle filled with a 20:1 mix of water:water soluble cutting fluid. I just kind of kept the engravings full of the coolant, and flushed them out when they started getting full of chips. I didn't do this, but now that you mention it some putty or playdough around the edge of the piece could have been helpful. I just had some towels underneath the machine to catch the drips, it evaporates quickly and the residue cleans off with a little Windex.

If you have a MDF spoilboard, you will have to be more concerned with the coolant because it will make a mess of your spoilboard with the quickness.

Absolutely awesome work! How did you paint the black on the bottom without getting paint on any of the walls?
