    This.. Tell me more or maybe a pic? Makes sense but sounds like it would end up being a sloppy mess around my world, not counting making heavy & nicely polished anvils more slippery and easier to drop....

      Cliff, they just sit suspended in maybe 1/2" of used lathe oil and when I return them to storage just give them a quick spin to coat. When I lift them out by the ends, I have a rag in the other hand to give them a quick wipe and then give them a further wipe when they are spun in the cradle.

    Cliff, here are a couple of shots of the die storage and oil bath for my larger wheel. They sit in maybe 1/2" of used lathe oil (Telus 46) - just enough so that when I return them to storage (because there is lots I do with crap flying around the shop) I just give them a spin and they self coat.

        Lower anvil progress.

        Got the lower anvil blanks machined up. Faced, bored and pocketed one side in the whizzy 3 jaw (has fine adjustment screw which can move it on the faceplate so that the workpiece runs bang on) and took a truing cut off the outside as far as I could. Second side was a matter of setting up in the 4 jaw, indicating on the turned OD by the chuck and on the bore, tapping it around so that the bore ran true. Some you get set up in a couple of minutes and others take an age chasing them back and forth with the DTI. Nice that when I took a facing cut off the second end, measuring across the width at 4 points was equal to within 0.005 mm. So they should run pretty true providing my mandrel idea works out. Only stuffed up one of the blanks with a bearing pocket +0.01 over the bearing size. I'll designate that blank to be my least used anvil - probably the flat one.

        Machined up the anvil mandrel from some 2" shaft and the idea is that the blank gets clamped on a machined step by the chuck, then located by a stepped spacer at the other end and clamped up with a spare 1" UNF nut. All of the dimensions are virtually size for size on the bearing pockets, so again they should spin true.

        Not looking to take full face cuts with a carbide tip, so the friction drive should be enough for the step turning.

          Po Boy's CNC

          Step turned 6 of the blanks for the small wheel and got the R200 one sanded to shape tonight. Covered the blank in layout blue and then sanded until the blue rings just disappeared. Very bad form I know, but used a 4" grinder with a flap wheel, the DA sander with 100 grit, then emery on a file with the whole deal spinning at 960 rpm in the lathe.

          Machined the corner radii just in a series of small flats and then blended by hand with emery on a file.

          Runout when assembled is pretty good at 0.02mm (0.00078") but the crown is slightly off centre when I gave it a test run on a flat panel. Plus it's marking the underside of the panel more than I'd like. Bit more blending with emery on a file I think. Certainly raises up the panel pretty quickly though.

          On the right track I think.

              Really nice work as usual Richard!

              For those who may have been trying to contact Joe Hoosier, he sent me a PM apologising because they had computer problems a while ago. He is making me a flat anvil with a small edge radius, which I will use for breaking an edge on long flanges,

              Cheers Charlie

                Wobbly legs - fixed

                Got some great castors from Richmond Castors in Penrose, but there was just a small amount of slop in the locking mechanism for the braked pair, which caused the machine to rock back and forth a bit when wheeling a panel.

                A moderately wise old git on one of the forums I post stuff on, did say that the castors would be trouble. However the shop needs the space, the wheel won't be used all the time, so needs to be parked out of the way when not in use. Hence some wheels are a must.

                Figured that if I made some stout legs for the front, stuck the fixed castors on the back and then spent several days making a fold away handle for the front, that I might be on the right track to have both mobility and stability.

                And so it came to pass...

                Fixed legs work as expected and might glue some thin rubber to the bottom of them once they are plated or painted.

                Fix wobbly stuff - tick.

                Had some issues with the keyway which prevents rotation of the anvil post, in that whilst the keyway was machined square to the anvil carrier, I'd stuffed up the keyway window in the lower post and it was slightly offset.

                Bugger.

                A gnat's whisker of error here meant that the anvil was not sitting square to the upper. The fix was to file an angled relief on the left hand side of the key, to allow the post and keyway to rotate to align the anvil carrier and upper. Once I had sufficient relief to allow the correct alignment, I then built up the other side of the key with some silicon bronze and filed up to fit.

                Pretty chuffed with the alignment now and the raising and lowering action is very smooth.

                Next is the fold away maneuvering handle and the covered toolboxes and oil baths for the anvils.

                Stout little legs, just like the operator

                Made the plates a light press fit onto the spigots and trued up the lower plate in the lathe before welding on the top mounting plate.

                  We might just call it 'Thomas'...

                  Nearly there with the 0-2 narrow gauge saddle tank.

                  Got a bit of time on the toolboxes today. Bit of a dork mistake in spot welding the hinge to the base first and not thinking things through. Turned out I couldn't get the spot welder tongs in to weld the hinge to the inside of the lid return. So some aircraft rivets instead.

                  Got the angle iron frames formed and welded to the main structure - the boxes just slot in, but need to be 30mm clear of the main frame to allow the lid to clear.

                  Lower anvils sit in a trough into which I'll stick 15mm or so of oil.

                  Couple of posts to machine up for storing the urethane upper and storage of the solid upper when swapping them over.

                  Bit of a sandblast, some grey 2K Glasurit and it will be done.

                      Cheers Neil - pinched the design from my uber metalshaping god mate Mike Roberts and gave it a couple of OCD Pykett mods. Jiggly machine and then I'm done, promise...

                    50 shades of Grey...

                    3 stage Mothers Wax and she's done.

                    Tracy at Acme Electroplating got the electrogalving done yesterday and I got some time late today to clean up the shop and assemble the wheel.

                    Rise and fall of the post is really nice now with some grease on final assembly and 20mm of old lathe oil in the bottom of the anvil trays allows the anvils to be spun and coated.

                    I reckon it's done.
