Our Shop / Re: My week this week, my workshop videos!
« Last post by hermetic on Today at 04:30:48 PM »
Fixing a VW camper, stripping printers for steel rod, and finally getting the toro 2CV engine running properly! I did drive it backwards and forwards in the workshop, but turned the camera off when I thought I was turning it on, what a plonker! It is seriously a relief that I have got to the bottom of the problem, carb was dry, and fuel pump not lifting fuel, so we know if it will not restart in a few days time that the pump valves are suspect, and the fuel is draining back to the tank. The moral of the story is don't leave engines standing for 20 years, and then expect to put them back into service without a bit of a fight!
Phil, April showers in May in East Yorkshire!

Nice one John! But....

You think you've got trouble!
 I've just had cataract op, on my left eye. Marvellous job! Everything is clear and bright. Through the new lens.  :thumbup:
The right eye, is still short sighted, and a pale khaki colour.  :palm:

I'm having fun, with single lensed reading glasses.....  :scratch:

My solution was to tap the bore 1/2" X 32 and make a double ended draw bar 10mm X 1.5 , so the head moves less than half the distance of the draw bar , it's still working after 5 years on my MT3 collets .

My question is on the Bowman cylinder is the pivot pin originally screwed or pressed in .I have bought two Bowman 300 and the pivot pin protrudes in to the cylinders damaging them. I will make new cylinders and solder them to the old bases.
Regards Peter

Hi Peter. Welcome to Modder.
 I'm pretty sure, I copied the original, and screwed the pivot pin into the cylinder base. The tapped hole in the base, was deeper than the pin's thread length. So, it couldn't do any damage.

Has someone replaced the pivot pin, with studding... ?  :scratch:

Necroposting. Dave, that's a great idea. I need to do this for my Johannson B12 mill, the precursor to the Atlas/Clausing 8520. My spindle top is exactly like yours, but I have a big threaded nut that threads onto that outer 3/4-16 threading. It has a set screw on each side to keep it from spinning off, I guess. How's your ejector tool holding up? Any design changes, etc? Thanks.

Hi I am new to this group and not sure if this is the way to contact you .After reading your excellent artical ,My question is on the Bowman cylinder is the pivot pin originally screwed or pressed in .I have bought two Bowman 300 and the pivot pin protrudes in to the cylinders damaging them.
