Ma
Many thanks for reply. Yes it is the back of the board , haven't had time to take it apart to get a good look at other side . It stopped working when I was tak spotting up just behind the welder. Would have been pretty easy for a bit of spatter to go on the transistor block I can see on...
Well disaster has struck and my thermal arc fabricator 211i has died. I think a spark went through the back vents and has shorted something. Actually really disappointed in the design as the boards appear to have no coating and no filter on the vent.
Anywho, I need to try and get this thing...
yep its mine , replaced with way too large lump behind it ...did i say too large ...na not possible.
Its a rare old wee beasty bred in oban scotland in prob 1940-50 , seen little use , all the extras u could want for something this size.
old video of it below , the 3 speed bicycle gearbox...
Its an xsy-at1 rated at 2.2 kw . Bit baffled as to why its blown as the motor was just sat on the bench. Getting the motor checked by sparky at work and have ordered some 220 ohm 3 watt resistors which i thi k these were. Its kinda weird.
Well decided to wire in new main 1.5kw motor.....bugger the pixies in the 2.2kw inverter escaped. Labeled as yr1 and yr2 , look like resistors. Totally fried .
Well capacitor took a while to get here but it works , takes a reasonable grip of my fingers to stop the shaft so it should pump OK.
voltage over the capacitor is 170 v , supply 240v and final phase 380v . Not sure if i need to go up or down in value to get it better ballanced , or if its even...
cheers folks , have bought a 8 uf cap to see if it works . unfortunately is permanently wired 440v no star delta options ....so hopefully it has enough oomph to work
Anyone throw a guess at what size capacitor i'll need to make this 3 phase sump pump motor into a single phase. Its 440v 0.1kw , going to 240v single phase with capacitor . no real load so might just work
Or could I just parrallel it to the main motor running the VFD, got a feeling its a dumb...
Yea its huge overkill carl ,
Have got it all back in the way i think it should be. 3 breakers for lights/pump/dro. 12v power supply for led lights and speed sensor. Will need to buy some glands n crimps to finish it off.
Couple of toys arrived from banggood, knurler and some carbide. Made a wee box spanner from a broken 1/2" universal joint and dressed up the chuck. Knurler is ace but the carbide took a beating on the chuck.
Also started painting shrouds but my freebie 2pack paint doesnt like the cold so will...
All done on the DRO , ended up screwing the alloy angle directly into the scale ends. The end caps on the scale are just alloy blocks so nothing to break dong it like this , not an ideal safety cover but the room was tight and it is nice n easy to do . If you get one of these chinese DRO kits...
Never actually thought about that, would a slippy shim work , as not too keen on fafing about with a proper bearing. And theres enough talk about bearings already:laughing:
Yep cross slide does have some issues, but we have the technology, well a half working lathe and an old warco mill to bash some modified parts out. New swivel bolt thingies as old ones were soft as cheese , and extra long toolpost clamp. Made from silver steel shim cut offs and old pipeline bolts.
Its a coil for a Chinese induction heater , https://www.ebay.co.uk/itm/1000W-ZVS-Low-Voltage-Induction-Heating-Board-Module-Coil-Driver-Heater-DIY/253829560280?hash=item3b196bb7d8:g:MtcAAOSwPJxbf7a~:rk:42:pf:0 . its a fair toy , just run it off a couple of car batteries.
Cant unfortunately...
So few niggles getting it straight
The end caps aren't straight to its length so i just clocked on the main box of the scale.
The scale was slightly bent , only about .2 mm in the middle , gave it a wee tweak and it was good as new , but i doubt it would have made a difference if i had left...
Not sure what the suplied brackets were about, pretty much useless (got 2 of those ones on the left with it) . Cut one up and made a block to fit the long scale .
Hmmm, cross slide is going to be a tight fit and the protective cover that came with it is going to be too much work to make it right or useful or pretty.
So have spaced it with 3mm drill bits and ordering some 30x40x3 alloy angle to use as a guard. But how to fix the guard hmmm.
