Some pics of my electrical update - it got a bit more involved than I expected! :proj: The VFD installation on my Holbrook was a bit of a lash-up (made by me, I freely admit!), so I bit the bullet and made a new electrical panel, with modern components (it's hidden away so it doesn't show!) and up to modern safety standards - no more exposed 415v terminals! (OK, I still have to make the "safety" cover for the Frankenstein switch, but it's in hand!) The panel has circuit breakers for *everything*, contactors handling power switching, relay "logic" to make the original "coolant" push-button toggle the suds VFD on and off, connections for the original switchgear (with a couple of additions) and "ET's little brother", the VFD remote panel with motor-current meter, 3 speeds and variable control, worklamp switch etc. - all control circuits are now either 24v from the VFD or 24v AC from the control transformer, originally they had 415 running through them :zap: The original Frankenstein switch is retained for the 3-speed 415v motor, otherwise it just wouldn't be a Holbrook! Both VFDs (spindle and suds) are located on a pull-out "drawer" in the base cabinet so they don't show - wanted it to look as original as possible! The panel itself fits in (I've checked...) the "bread oven" at the headstock end of the base, so they don't show, either! Anyway, before and after (as far as testing on the dining-room table... Still have to tidy the wires and bolt it in, maybe this weekend!) Dave H. (the other one) |

Blimey Dave, you certainly went to town on that lot.... :clap: :bow: :bow: As someone who comes from an electrical/electronic background, I can appreciate how much time and effort has gone into your panel wiring... :zap: |

I know absolutely nothing about the electrical stuff. I wouldn't attempt it... if I did, I wouldn't be around long! That is nice and clean thought. Very orderly. Eric |

Dave. Very impressive....... :thumbup: David D |

Ah, but where is the magic smoke release button? |
