Some of my stuff

Here's some of the stuff I've made using my Billhog.

2009 Honda CRF450R Radiator Guards:

I haven't tried aluminum on my CAMaster. That is an excellent radiator guard. Nice work Unabiker.

Nice work! What type of aluminum? Soft, hard? Not sure of the numbering. I cut some 6061 one time on our ShopBot, to make the bracket for my gear drive on the 4th axis, TOUGH STUFF! Did not have a mister so I just armed myself with some WD-40 and let her chip!

Anytime you can please post more photos and descriptions of your projects! You are truly an asset here at CAMheads.

Saw your Youtube Video, I love the roller setup on your machine. Is that custom or did it come with your machine?

All of my guards are made from 6061-T4. It's more towards the hard end of the spectrum. The harder stuff cuts better than the softer grades. 6061 chips off really nice. Stuff like 3003 is so soft and gooey that you really need to crank up the feed rate in order to keep the heat out of the bit. Assuming a constant spindle speed, a faster feed rate will give a thicker chip, which will carry away more heat.

For the mister, I run Koolmist and water...4oz of Koolmist to a gallon. The Koolmist is more for corrosion resistance than anything. The amount used is very small too, about a pint per hour.

The roller system on my machine is my own work. Nothing too fancy. A couple of steel tubes with some roller bearings on either end, some arms to hold it in place and a bungee cord for tension.

Each end has 4 basic parts; 2 bearing carriers, the roller support, the swingarm, and a few stub axles/ pivots.
I did the bearing carriers on my lathe. The roller supports and swingarm were done on the CNC. The whole thing is bolted to the gantry and pivots on a couple of 5/8" bolts.
In the past, I had been gluing down my aluminum to a spoil board and using a torch to release the glue. Then I would have to clean everything off in a parts washer. This works fine for smaller volumes, but is a decent sized pain in butt if you have to do it a lot.
With the rollers, I use 8 drywall screws around the perimeter to secure a 4'x4' piece of aluminum to the spoil board. The rollers keep the metal from lifting up as it's being cut.
With the amount of material that gets removed, I don't think there is a vacuum system made that would keep things in place.

This week's to do stacks:

I sell everything through my website, www.Unabiker.com and through an ever growing network of dealers throughout the world. I advertise on a few websites and have a lot of guys around the country running my stickers and talking my stuff up. Best advertisement is happy customers.
It's never ceases to amaze me that I can make a living doing this.
