Good stuff  :thumbup:



I  run my mops at 1800Rpm now, cause I'm comfortable with that.  Just be careful.... If you slacken your grip or put a sharp (E.G. 90 deg) edge to the mop too quickly It won't half take it off you and launch it  :bugeye:



Pic's of the results will no doubt turn up on your engine build posts? I look forward to hearing/seeing how you get on.

For a preliminary discover:, I need to sand off most of the tool marks before going to the lathe.  So lots of work there.  Given that SFM on the mop is supposed to be 3600 SFM, I turned the lathe up to 2400 RPM.  Tomorrow I'll see what results I get on brass with the first mop/abarasive.

Here's a pic of my arbor on the lathe:



I did some trial runs on aluminum and brass parts, after filing and sanding.  The abrasives I have on hand are the 180/240/360 set of aluminum oxide "tape", plus the purple Scotchbrite that I think is around 600.  My conclusion is that I need a coarser grade to remove the endmill marks, and also a finer grade before using the buffer.

Thanks for the offer bogs, although Im afraid I live in South Wales.

Hi DJH, I know this post was some time ago, just wanted to say Gday. You're in South Wales correct? That would be old South Wales right? You see im in New South Wales..... only my South Wales is in another country....

It seems when our British forebears colonised the wonderful rock known as Australia.. they got homesick or at least some wag from South Wales did..... hence this state is NEW South Wales.....

Only... gets a damn sight hotter and no where near as cold.......  :)

Cheers Artie (yes I know....worthless post... again....)
South Wales, wait...NEW South Wales... Batemans Bay.
