  • The question of billet

    I got stuck in the bar the other day with the local gear head moron ( my car puts out 6000 hp because I bolted on all this junk and added up hp on each box the junk came in.)
    Anyway, I showed him 2 titanium 14mm castellated flange bolts I made for my friend. His response " That's cool but
    you can't make billet stuff at home cause you need speical machines and ****" .
    I never knew this until he pointed it out
    boy, do I feel stupid.
    Non, je ne regrette rien.

    Well, you prolly weren't lookin but YOU may have that special "****" in yer home shop needed to make that billit stuff. Guys like that cant be educated cause they know it all.

    Billit has become the "2000's" catch phrase. Must blame some of it on TV and more so to the aftermarket auto industry. They make it sound like an "unobtainium" special material only used for high tech products.

    Now, turning Ti is new for me. Does it cut like Al or 4140? JRouche

        titanium is grown with fancy crap (retort) and they call it "sponge" it is half magnesium and will burn easy.

        I call titanium a crystal metal.

        do not machine it unless you know what you are doing and do not let the chip slinger catch on fire.

        JRouche it can be a dirty rotten bastard to turn and hard as a freakin rock, it turns ok in a cnc with a waterfall of coolent and top of the line inserts.

          It is tough to turn but I haven't had any problems, sharp tools and coolant but I have also tapped it by hand, grade 5 is what you want to use.
          I haven't started any fires but it looks cool when you sandblast it.

            My limited experience with titanium (dunno what alloy it was, which undoubtedly matters) suggests that it cuts okay with wicked sharp HSS, and cutting it generates an astounding amount of heat so some kind of coolant is probably a good idea (I used mist).

              I love this topic!
              For several years now I've been trying to cook up things out of 6061 alu that the hot rod guys just can't live without.
              Last summer I took some of my stuff to a car show to get feedback etc.
              A bunch of the "experts" gathered around to look at it.
              The "leader" asked me what the stuff was made out of.
              I told him it was all 6061 aluminum.
              He says "Cool stuff....too bad it isn't billet!"
              With that the "band of brothers" turned and walked away.

                  Chief, the nice thing about ignorance is that it keeps you in a state of perpetual bliss! I'm in that state now. Just spent 20 minutes googling for a picture of a "castellated flange bolt" just in case I one day run into a box of'em at a yard sale. After looking at some 20 sites I find not one pic! I'm trying to keep up with you big dogs but I'm getting short on breath

                    "Billet" is a classic example of common usage in a group noted for invincible ignorance triumphing over precise technical language.

                    A "billet" is the term used to describe the material in its first stages of a hot rolling process. "The billets are heated then run through the first stand of rolls..." Before the billet was a billet it was a "bloom" and before that it was a "cast ingot." "Billet" is the material form in an intermediate step in the rolling process.

                    In the machine shop parts can be made from hot roll, cold roll, plate, welded fabrications, castings, or forgings. But never "billet". Billets never get to the machine shop because they're an intermediate product in the rolling mill. Strictly speaking it's impossible to make stuff from a "billet" unless the material was purchased in the billet form from a rolling mill. I dare say the mill would be entirely be justified in removing all the material's identifying marks and requireing the purchaser to sign a waiver of warranty acknowledging the purchased material's properties were incertifiable and its processing to commercial standards were incomplete.

                    In short actual "billet" material can very possibly be substandard compared to material that's fully processed and heat treated.

                    "Billet" is strictly a hot-rodder's term used to cover parts machined to net shape and detail from solid stock. "Billet" as a material identifier does not signify superior quality. Quite the opposite: in fact, "billet" rocker arms, connecting rods etc might be inferior in ultimate strength and reliability to identical products made from net shape forgings where the materials grain structure is directed to maximize its resistance to stress.

                    So when you see "billet" proudly printed on a colorful box of hot-rod goodies think "bull****." There's hardly a segment of the market place so bamboozled and led by fad and hysteria as hot-rodders unless it's buyers of cosmetics and male enhancement products. Ignorance and folly among purchasers is actively fostered by makers of hot rod products - purchasers who spend mountains of money to secure the last iota of performance from their favorite overweight, unreliable, unstreamlined, obsolete POS.

                    People who build hot-rods and race cars are building nothing more than high performance parade floats. They're made for glamour and to excite envy among the cannaille. The apotheoses of fast cars are Formula 1, Indy cars, and unlimited dragsters. Anything less is the province of wannbes and dreamers.

                    So use "billet" as a general material descriptor if you wish but by doing so you flaunt your ignorance of materials and their designation in the industry. If you're working in a machine shop such usage will brand you as a dunce, a wannabe, and if a customer as someone to relentlessly fleece by making them "billet" parts from plate and barstock and charging them extortionate prices.

                      Come on Addy.....Don't beat around the bush.

                      If you've got an opinion on the subject, just let it go. Holding your thoughts and feelings back can cause indigestion.



                      Just kidding.......Rodg

                      BTW.......got a guy a work that "swears" that BILLET machined parts are the best thing since they invented the spark plug.

                      I tried to tell him that it was just a part machined from a "solid" chunk, but he wasn't buying it.

                        Damn. I *had* some billet, but I f***ed it up by sticking it in the mill vise and making a fixture out of it for work. I feel stupid. And contageous.
                        The curse of having precise measuring tools is being able to actually see how imperfect everything is.

                          Forrest, what passion, pathos, and big words! I laughed, I cried, I got out the dictionary. That was beautiful, man.
                          I'm here hoping to advancify my smartitude.

                            When someone asks me what I make a muzzle break out of I tell 'em I start with a solid piece of steel. When they ask "billet"? I just answer "yup". It's fun watching them ooo and ahhh.

                              I always thought the words "machined from billet".
                              ment machined from a solid lump of whatever steel,alloy etc.
                              rather than the part being cast,pressed,fabricated.

                              So these hotrodders are now reading there hotrod mags.......and misinterperating the word billet as a marvel-special-metal....ha ha ha.

                              So Chief.......all you have to do to sell your stuff ...is call it "Titanium Billet"..now that would sound even more impresive to them backwards wearing baseball cap guys... me thinlks.
                              all the best..mark
