I must say that carbon fiber is one of those love hate relationships. it is easy to shape but goes through sand paper fast, plus it is a huge mess. It looks amazing but makes me itchy. Any tips on working with this? also should i seal it in any way or just polish it. I have almost got the 2nd Amendment defender knife done and you know what that means, time to call bubba-doll for picture time ;)
 
I've been making slipjoints with carbon fiber, no liners and pins only for pivot, spring and elsewhere. I relieve the sides, and pein together. It is the most unforgiving material in that you cannot loosen the knife up. The peined pin simply does not budge. Normally if I pein a little to hard the knife binds up. I wedge it open a bit before sanding pins down or before doming and it works pretty easily. Not with some of the man made materials such as carbon fiber, G10, a type of material made with kevlar that I use(don't know the name..bought on ebay). They hold like hell. The only thing I have noticed with a liner less slipjoint is that after a month or so of using the knife...it becomes a little stiff as if it wanted lubrication. The SS to blade normally gets easier and easier to use..not true with CF. A drop of oil though loosens it up for another month or so. Makes a pretty knife if you like the look of carbon fiber and it is tough! Sands and shapes very easily, almost too easy because you can take off too much material fast. Once the shaping of the handle is complete, a little hand sanding and a quick buff, and it looks good.

Looking forward to seeing them both! ... I know this is off topic, but where are you at with the calendars?

The only way you are going to keep from getting itchy is to wear nitrile gloves, and cover all areas exposed. That can range from wearing a long sleeve shirt to going the full 9 and wearing a tyvek suit, and tape your wrists to the gloves. Another plug for wearing a decent respirator goes here too...
 
well the knife is done. and bubba-doll is coming over to model it for me :D i will start another there later with the pictures in it.
 
All I will add to this is that CF is an extremely hazardous dust to breath. Wear ALL the proper safety gear, and vacuum everything well afterward. Due to the light weight of the dust it gets everywhere.

when you say extremely hazardous do you mean, extremely hazardous or EXTREMELY HAZARDOUS
 
that itch with carbon fiber is bad, but if you put lotion on your hands and arms before you start to work with it it helps keep it out of your skin.
 
While I wouldn't rate it the same as grinding cyanide eggs into powder, it is very hazardous to breath. The damage to lung tissue from long, thin firers has been clearly demonstrated. This is a fairly new product, but I would foresee similar long term exposure to that of asbestos. Who knew then? We know better now. Particle and dust containment is an absolute must. Also, remember your pets and children who visit the grinding areas.
