has anyone tried these for aluminium get a pack of 10 rods £13.00 thought i would give it a try all you need is a plumbers torch tried it today with 2 mm thick alloy sheet with a bit of practice it works well i turned a bit of 6 mm alloy under size built it up and turned it to 6 mm and threaded with great results

i was a bit sceptical but it does work well

Geoff

hi George making the same engine

Geoff

checked all settings bit of a blonde moment when setting the y axis used edge finder as 4 mm dia should be 5 mm so .5 mm off center now no fillets but it looks to me that the journal has a slight rad ?? any help please

Geoff

Morning all from the replies it seems that i have the y axis off creating a fillet in the corner

the a axis is left on the mill all the time i will check the set up this morning. mach 3 does lose it self, i relied on it remembering the y offset

anyway off to specsaves this morning to pick up new glasses that might help will let you all know how i get after resetting and checking the setup and running another test piece

thanks Geoff

the cutter is an 8mm flat slot drill i think its the video gives the impression its a rad cutter

Geoff
