Tools / Re: WM250 change gear assistance needed.
« Last post by picclock on May 26, 2018, 06:27:42 AM »Sorted - The leadscrew gear dos need to be changed and the H 's on the change gear list refer to spacers which are in the tool box.

Oooops! / Crash, Bang, Wallop... Got a picture
« Last post by Joules on May 26, 2018, 05:56:31 AM »Well two pictures. It has been years since I crashed a lathe, complacent ? I was threading up to a shoulder using the new-er BIG lathe. On the Myford I have the clutch, so disengage threading once the tool is in the run off groove. The new lathe I have done a few test threads and some parts where there was no run off required. I got caught by the fact in low gear, once you kill the power, inertia keeps the chuck spinning way too long.
Well beyond the run off, then I forget the foot brake in my surprise that the lathe tool has just hit the collet chuck. Then the "SNAP" as the lead screw shear pin finally has more sense than me.
Amazingly very little damage to the threading tool, just the very tip got knocked off. Backed everything out by winding the lead screw back as the lead screw nuts got jammed in the crash, and survey the damage. Mainly the shear pin and collet nut. I cleaned the nut and it still works with no added runout, tested with the collet in the picture. I made up two new shear pins from brass stock I had in. Figured making two at the same time was a sensible idea, you see the broken and one of the new, the other one is fitted below in the lead screw coupler. Got back to the thread cutting by cleaning up the shoulder, realign the threading tool with the cut thread so far and finished it off using the brake when the tool reached the run off.

Tools / WM250 change gear assistance needed.
« Last post by picclock on May 26, 2018, 04:24:04 AM »Hi
Am trying to set up for a 20tpi thread, which should be a doddle according to the label on the machine. However i cannot seem to be able to get the gears to fit in the banjo - there does not seem to be enough room. 30-80 and 75-60 seem to be the gear pairs, but it is impossible to fit the 80 upper gear with either the 75 or 60 lower gear in place. I am assuming that the leadscrew fixed gear is not changed.
Can anyone with a WM250 care to shed some light on this.
Best Regards

L = 1 turn from closed).
Are the crankshaft seals still airtight? Leaks might show more now that your piston is new.

How do I?? / Re: Anyone Ever Shortened a Shahe DRO Scale?
« Last post by WeldingRod on May 25, 2018, 05:27:15 PM »I've cut those down too, even going so far as to peel off the working bit and graft it into a lathe cross slide!
I have also cut down a GLASS scale, but that's a lot more fiddly!

Doesn' that engine need high quality oil bigger than normal %? Here if you rent the saw (100€/day) they give you the labeled canister of gasoline to go with it. Rental comppany inform to use only that, because it seizes really quickly with normal two stroke oil/gasoline.
Had to rebuild some carbs long time ago....some diagraph/gasoline combos seem to work better than others. Remember changing the fuel line and the clunker in the tank.
