        If properly displayed in some kind of cheap bubble pack........who knows?

        I would eliminate the close up photos for any advertising.

        Now tell us the truth. This piece is off of a K-Mart special. Right?

            Not sure what it is but looks like a lot of really precise work went into it. Good job!

              Nicely done! Say it took onlyl 10 minutes to knock that out? Looks like a lot of setup time involved.

                well i'd like to think its a precise piece, just because according to the dials and everything i was approaching it precisely. Actually the aligning went really quick, i think my dial indicator is infused witht he precision of the GODS! When i was setting up the piece and the vise to be square, twice i managed to get it perfectly square (by chance) before testing it with the dial indicator. The grooves arent actually that bad irl. Its not a kmart special u wont see any engraving or tags on it! Yesterday i sharpened a cutter for my fly cutter with a large cutting point radius, then tested it. I was so pleased with the results that i decided to "heat treat" it (crazy? or stupid? you decide!). Its cutting way better now i'm telling you! Im not yet sure of what to do if it shatters... lol...
                Its definitly a weekend project, it just took a bit longer because i wasnt sure of how to do certain operations..









                for the cutter i heated it until it was bright red and then put a few drops of motor oil until it lost it's color, then quenched it in a mix of water and motor oil. i guess i got lucky.. I probably wont be doing this again because I will probably end up buying a used indexible face cutter.. Cheers!

                  That's very nice work Elninio. What alloy did you use?

                    probably 6061, thats what it looks like compared to other aluminum parts on my bike, when we went to pick up the aluminum, we just took generic pieces of scrap. costed about 6 bucks for a 1.25 x 1.5 x 3 inch block. Its a prototype, so it the alloy doesnt really matter at this time , just wanted to have a project to do on the mill. Still makeing changes in the design in order to make it easier to machine.

                      Elnino, if you went into production on these why wouldn't they be cast? Seems to me that would be the way to go. Have them cast and then bore in the two holes and tape the threads.

                      One place that does small size orders that I know of is called Buffalo Metal Castings in Buffalo, New York. You might want to give them a call and see what 50 of these would cost you and what variance in tolerances they can produce that you can finish process at cheaper prices. Could end up saving you a bundle.

                      Also, why did you heat treat the HSS? I thought HSS bits were air hardening but I may be wrong, someone will know.

                      If your working with oil hardening steel there is a simple trick I learned from an engraver. Dip the cherry red steel that has soaked for the required time in a empty chicken noodle soup sized can filled with 10wt parafin base motor oil. Dip it right in the middle of the can and don't swirl it. Leave it in there about 3 minutes and the hot jacket of oil surrounding it will self anneal it in one process. It works great for me.

                      good luck, looks like fun project

                        Why are you doing this?

                          I like it, 'Ninio.

                          It is about time somebody started shaving bulk and weight off those. I like yours; very clean. I really like the Odyssey one too though, the uuh whatthehellsitcalled, simple one-bolt one.

                          (Psst... tell ya something nobody else here knows: I still ride. I'm 37. Started riding in '83, and got a new bike six months ago after a twenty-year lapse. Lovin'it!)

                          Your Old Dog, no... casting is (usually) just not applicable for reasons of strength / fatigue and so on. C'mere for a minute; check this out:

                              Un-freaking-real ! I can only imagine what kind of a adrenalin high that's got to be to be able to pull that off. I got drunk doing an occasional wheely on my motorcycle but this is waaaay over the top. Thanks for taking the time to post the link Dr. Rob.

                              Until my ankle mends this electric scooter is the best I can do for thrills ! But I have to say the other one (Bombardier 650 Max XT) will give you a cheap thrill too!
