    Nice metalwork. JR

    • Gorgeous as always Zahnrad. One thing I've wondered: how hard would it be for you to produce a herringbone gear? I don't need one, but it must have been expensive for Sidney to produce them back in the day. They must be shaped, right?

          Hob (or otherwise cut) two helical gears in opposite directions and press fit them together on a common hub?

          @Zahnrad Kopf: Nice. Wish my change-gears looked that good. No massive need to, but there's something nice about something made with pride.

            Thank you, Sir.

            Thank you very much. Typically, they are made on special machines. ( Shapers and Planers )

            Thank you. Appreciate the kind words. I try very hard to maintain a certain level of aeasthetic quality in addition to technical quality in every job we do. It's important to me.

            Thank you. It looked a little bit like this... ( had to dig a little find the picture )

            • Here is a pic of the brake I was working on for Gambler.
              I milled approx mm off the outer edge of the stainless rotor, then made the notches which eliminated one of the drilled holes.. to look a bit more like the other rotors on the Bike. The guy had a pic of what he wanted, so it closely resembles that.

                754, That looks really nice.


                I continued work on getting a 5 ton arbor Dake arbor press back together that someone chopped the front end off on for a custom application. I've got to finish the clearance hole for the daisy wheel, do a little sawing, touch it up and it's done. It's been a lot of labor so far. I needed a 3.5" hole, so I ran a 2" bit in the Royersford and am boring it to size now.

                • Got the 3.5" hole finished. Now it's just up just up to dad to debur everything, clean it up and mount it and the press will be back in service.

                      That's right, 5 ton. Non compound, so it's got like a 5' lever on it. I'll post a picture when it's done.

                      • V shaped rollers for an unknown (to me) purpose.
                        304 SS, 2 1/4" OD with a 1.127 +.003 - .000" bore and a retaining ring groove. They are .88" dia. thru.

                        • Bented Look nice to me. Like shiny
                          Gotta love the rust resistance of SS. Similar to the "Must be carbide because.... better" mental trap SS was an issue for me because....well, you don't want it to rust, now do you.

                          Spent some of the day playing with a Veritas honing jig. Bought it a year or three back and have been whinging about the sharpness (or lack of) of my chisels on the very odd times I've needed to use them. Found the credit card size d diamond plates weren't bad for cleaning up the surface of my dad's old whetstones. I think one is possibly carborundum (sort or rust coloured - slightly pink/orange even) and the other I think may be slate (very soft - easy to scratch and scratches white).
                          Made much faster progress with a 1000 grit water stone than the course diamond plate. I reckon they're fairly lethal now :-D
                          Now if I can only work out a reliable technique for edges that aren't as simple as a chisel!

                            It was actually 303 SS, a world of difference from 304 as far as turning goes, it has a rather dull turned finish when compared to 304 or 316.

                            303 is well worth the added material cost if you have to make time on the job.

                            • Bented You mean that it doesn't look as pretty but is far less of a pain to machine? If so, that's worth knowing. I like some of the harder steels (higher EN numbers) for the reverse reason; it's technically harder to machine but the finish is so much nicer

                                Exactly, it is a free machining alloy designed for production work. Often called screw machine stock much like 12L14 steel and 360 brass.
