Cowells Adventures
« on: February 04, 2017, 10:12:28 PM »
OK, since some of you (you know who you are) were giving me a hard time on the other thread, I just started a new one. Just as well, the old topic title wasn't appropriate anymore anyway.

After some rearranging in the garage, I at least have a temporary home for little "C". Enough to play around with it a bit anyway. That said, I found a stray piece of aluminum rod and went through facing, turning (both manual and with the geared feed), angle cutting using the compound, and so on and ended up with a tool height setting gage. Would be better done in steel but didn't have any handy of suitable size.

Anyway, got a feel for the handwheels, changing speeds, adjusting the compound, and the autofeed, so that is a first step. More adventures to follow, and as you can see it now knows what a bit of swarf is.

Nice!  Is this lathe on the scale of the Sherline?

Cheers,

Phil, slightly smaller perhaps but yes, comparable. The main difference is all steel or cast iron construction and traditional speed control and threading via the geared head and change gears.

Bill,
Good to see you've cut metal with it and the lathe's working ok.
One difference between yours and my older lathe is that Cowells have gone over to a more sensible dial marking for a metric machine. Yours looks to have 50 increments around the circumference of the dial, of 0.02mm each, with major intervals at 0.2 and 0.1mm.
For some reason my older dials are divided into 40 increments with major intervals at 0.25 and 0.125mm - I suspect they couldn't resist  overlooking that 0.025mm = 0.001 inch. However there has been the very odd occasion when working in fractions of 1/8th of a mm was convenient.

You are correct Steve, 50 divisions per rev. with major divisions at .2, .4, .6, .8, and 0 and intermediate marks at .1, .3, .5,.7, and .9 (less numbers) and smaller lines at each .02mm.

The important question: how does it feel in comparison with your Sherline?

Nice!    Smaller lathes have a feel all their own, and for small parts is so enjoyable to use.

Jo, I would have to say it feels incredibly smooth overall. The lack of a true handle on the compound may take some getting used to but in use it is far more rigid than the Sherline compound which is a separate attachment without adjustable gibs. From a power standpoint I would say they are about the same, though I haven't tried the back gear yet. I suspect that will provide a lot more torque when needed. Today I want to give the collet adapter a try and the QC toolpost as well. More on that later.

Dave, yes I think the Cowells will be used more for those small fiddly parts and for making small fasteners when needed too.
