      For local pick up at £100 who could resist. in the car boot (seats down) and home.

      A pleasure of a project so far, so im catologging it here incase anyone else has a similar machine because i found this quite unique. I wonder if it was a test model due to some added parts. . dual tapered timken head bearings,, , pin roller and ball race rear. widened cross slide ! extra parts are fitted to the outside sides of the cross slide. and a plate underneath. all will be revealed. I would love to know if anyone has seen similar I can't find another .

          Brass changeplate has no manufacturere marks I can find.

          Headstock removed 4 bolts, gap bed. rear leadscrew gears in place crosshatched bed002_headstock removed.jpg

           

          Headstock siezed, both gear changers pins siezed, the right one came free , the left i had to hacksaw through after three weeks of occasionaly brutal encouragment to leave the hole. I tried punching out from the inside . no. hacksaw, lever came off ok, then drilled the pin out, came away in the end.

          003_headstock_start.jpg

          First gear came off theh end of the leadscrew ok, with a bit of woodruff key, alarm bell should have started.

          004_first gear off leadscrew.jpg

           

          Who did this. and didn't tell. . To get the second gear off I had to needle file the offset lip down. Yes I also cracked the cast iron gear holding pick up arm TIG back with nickle . Everything was rust siezed. . days .

          005_leadscrew bent wudruff slot.jpg

          the upper ring is threaded on the shaft and holds the Timken bearings together , it needs to be gentely released and the shaft tapped out forward as there is very little slack in the mid stage assembly. Pig of a job, my hope of saving the upper bearing was futile. I did terrible things to many parts befre I understood the mechanism of harmless seperation.. 008_headstock_front_bearing_threaded_retaining_ring.jpg

          Going through the photos I have now spotted the three grub screws I have left in a tray . they are from the lower wheel set not part of this image. Dohh. It was running rough through the head gears.(direct its smooth and quiet)

          So I bought a crappy old machine that turned out to have serious bearings in it.

            That is a strange one. The hole in the gap bed for a start . The bed looks complex for such a small lathe, more like a tool room machine but they are usually plain turning lathes. Have you spoken to Tony Griffiths ?

              Ive not spoken to Tony but I would happily take some picks for his very informative site. I will ask,

              The "B.E.C.11470/15." stamped in the bed end ,I found only a few days ago and spurred me on to post the work. It was a pure joy when the seriel number caught my eye , completely hidden by the origional corrosion. B.Elliott & Co , doesn't look like any of their machines (cross bracing is similar) but works in Cardiff and I bought at Wooton Basset, not far.

                Brass shims under the saddle front underside slide.021_saddle underside.jpg

                Locating C pins aligned the saddle front and its bed plate, These were the only two C pins on the whole machine when it has so many solid pins.022_saddle_gearbox.jpg

                and finally to bed, that black scaly paint was probably full of lead so I took it off with acetone where i wasnt making dust and soaked it into workshop towel, outside.

                The saddle grips around the outer edges and teh v , the tailstock on the inner only .

                Someone loved screws , plate added, leadscrew nut steel not brass. , two side extensions with gib adjusters

                  How did this coroded metal look so good in the sellers photos. I'm still glad I bought it.

                    Soft focus filter software!

                    I wonder if those ball bearings are a mod by a previous owner? Looks like maybe they were added on using a sleeve where the original bronze plain bearings fitted? Certainly different.

                      Stuck a bit now on alignment , need to align the headstock and the tailstock .The headstock has four capstan ? bolts which allow head alignment. Also image searching brought up an ME posting on what is suggested to be an IXL lathe and mine is similar but with changes. I wonder if BEC bought machined castings from IXL as there is no branding on the castings or screwthread plaque suggesting IXL. Mystery. Anyway it has a 1HP 180V DC treadmill motor on it now and a new chuck on a 1 1/12 " x 8tpi backplate. So its running just completely unaligned.

                      Makers mark or inventory stamp

                        running .jpgRunning better on the 1HP 180V DC treadmill motor than the 350W clarke drill motor I canabalized and had to reverse the start direction which I forgot I had done when I re-assembled it . doh. £26 for a 0-200V motor controller and £60 for the motor. Still need to trim the headstock and tailstock, guessing a 3MT test bar is on the menu. Also on the origional treadmill motor, it had an encoder fan on one end and a flywheel / multi v belt pulley on the other, flywheel left hand thread screw holding it on. This fitted best behind the lathe running in reverse to its intended direction which meant the cooling fan blew the wrong way . No you cant just turn it over. I had to buy a pair for compressors and make it fit. Also made a small V pulley for the new dc motor.

                          Nice project.

                            I had an ancient (1890's) Melhuish treadle lathe with a gap bed hole like that. The hole was to locate a removable fill-in piece of bed, so the saddle could be brought closer to the headstock. Have a look at the thread What are member's thoughts on gap-beds ?

                            I built my first engine (a Reeves' 'Trojan' ) on that lathe. There's nothing quite like treadling to teach you the value of sharp tools…
