Glad you are sorted, today we had a whole 80volts in our mains, the myford ran at 43rpm then stopped but my L E D machine lamp still worked until i turned it off. |

In prep for the arrival of my 3phase kit for the Mill i have today gone around the shed and linked all the metal with a 20mm earth cable. this i also fixed to the shed earth plus a link to out side and a 5foot earth spike knocked into the field next door :zap: i have a good earth in the house also from when we rewired the place 5 years ago, down to my last 10mt of cable now. |

Now get a AC volt meter test the phase to neutral and take a note of it Now disconnect the earth conductor that goes to the earth rod at the point were it connects to your system , now test from phase to the conductor that your disconnected , it should be as near as damit is to swearing Do not forget to reconnect the conductor after the test Now this is not the correct method as it involves putting in temp earth pegs a certain depth and distance , but it's a good indication that you do have a earth not just a rod in the ground Have fun and be safe Stuart |

my 3 phase kit arrived today :clap: i had been to hospital so it was good to have some thing to play with to take the mind of whats to come...... :palm: unboxed it and carried it all around to the shed, spent an hour removing the wiring from he mill and rewiring to run the 110v power feed and 24v lamp, removed the switches and other guff and tested the power feed and lamp. Removed the old motor and checked all looked OK with the new one and fitted power cable and humped it onto the plate. i had to make a shim/spacer for the pulley to get it to sit correctly. Made up a new 240v lead with new plug and fitted the VFD to the mounting plate i made, Simple job to wire it up and it runs nice with a lot less din that of the old single phase motor. i am half way through making a a plate to mount the remote on the belt cover, pics if i can when fin.
