|  Ti plate source? Wasn't sure where to post this, so since I'm building a WK chassis, here goes: Anybody know where I can find a (relatively) cheap source for Ti plate? I want to build a plate type chassis and I'm trying to decide if I want Aluminum, Ti, or Carbon Fiber. I've seen aluminum 12"x12" sheet for around $16, CF 3mm thick sheet for $45, and Ti for $330!!!! (ack!!) Is Ti REALLY that expensive or is there another source (or perhaps a lower grade Ti) for cheaper? If that's really how much Ti costs, I think my decision has been made for me (CF)... thoughts? |

| Titanium is definitely not cheap. Good thing about it though is that if you were going to use 1/8" alum or CF, you could get away with about half that thickness in Ti due to it's stiffness and strength. |

| Titanium will be very slow and difficult to cut. It will also be heavier than aluminum and carbon(if used in the same proportions). Check eBay they have a few auctions selling sheets in various dimensions. I would look into buying a sheet of 7075-T6 and call it a day. It will be the cheapest of the three and the easiest to cut. If you are ever in the LA area I would also check out http://www.calaerosupply.com/ They have a good scrap section. |

| Cutting Ti sucks. Cutting CF laminate sheet sucks too. I would suggest you stick to aluminum. |

| Titanium bends more than 7075 Aluminum. Unless you are building in some torsional flex Titanium is just a bad choice. |

| Yeah also if you want to put bends into your design I would stick with a 5000 series aluminum. Another site. http://www.aircraftspruce.com/menus/me/index.html |

| thanks for all the input guys, I was mainly looking at Ti for the bling factor, but it's just not worth it. I still may try the CF, at $45 for a laminate sheet, it's cheap enough to experiment with. Also for the bling factor...  |

| Binary, Ti bends LESS, its very stiff. Its a very tough material to work, bend, drill and machine. Jbrandt, cutting laminate is easy, use an electric wet tile saw with a diamond blade, if you have one handy, if you dont use a friends. Anything else you have a big mess and less clean cuts. |

| True, but the water helps capture the pesky shards.  |
