Cheers krv3000 this mornings job was to make the con rod. Cut a length off 1/4*5/8 mild steel bar allowing a little extra on the length. Mark it out then drill the hole for the bearing, to get it flat place the bar on the table put the vice over the top and clamp up on the bar, that it nice and level with the top of the vice. Drill 8mm Then centre drill each end for turning between centres Its a bit of a awkward shape for fitting a drive dog to so, With the four jay self centering chuck turn a 6o deg point on a bit of bar. Set this back in the chuck then with a life centre in the tail stop, the chuck jaws act as the drive dog. Rough the material out rough shape and face the end to length leaving a pip. Slew the compund round 3 deg then with a radius tool finish off Flip it round and turn the other end at the 3 deg setting. A bit of work with a filing button and drill and tap for fixing the brasses and its Job Done Stew |
