    Hi all I haven't had time to poste much since the spring, I hope you've all had a busy summer, its been a busy summer down here albeit I haven't had time on the fergie or any of my own projects, its now starting to get chilly and the nights are getting longer so time to think about getting back in the workshop and almost time to be getting the fire on. I am almost finish sorting out a customers VW T25 loads of welding and body work I am almost ready to primer and spray it thank god. Ive been thinking of make a mobile air mover or extractor for moving the fumes out of the workshop for a while. Today I thought I would make a start on one I had a couple of woods spray booth fans under cover for a year or two or even three, so I figure I would mount them in an old heating oil tank. I had plasma a couple circles out and cut a piece from the rear and I welded some strengthening pieces in to hold the fans as they a quite heavy.

    So far so good this afternoon I managed to hopefully sort out the wiring, I hate wiring 3 phase for some reason I alway wire it the wrong direction fingers crossed, I fitted a switch inside out of any weather I am hoping to switch them both on and off on the one switch. I should be able to pick up a plug in the morning. I have never had them running so it will be interesting to see if they work and what sort of air they will move. If they are ok I will make up some sort of grill to protect ones fingers from the blades. Here a few pick from today fingers crossed for tomorrow

    Cheers

    Jord

    Update from this moring I picked up some M12 bolts to fix the fans in properly and a 415v plug and gave it a whirl, typically I had the fans going counter clockwise, so switched the wires about. I then had some grill materiel from a shop clearance the holes are about 2 inch squares and I though the holes were to big so I pinch some of father ½ inch plastic coated mesh and put that over the bigger grill does the job a treat

    made a clamp to hold the wires to the casing job done.
    I think after running them one fan would have done what I needed they push out a lot of air.

    I did mess up though I should have clean the blades and inner casing before I fitted the grills so will get round to cleaning them another time. I dont think they need grill on the rear of the fans as there is so much air coming out I dont think anything will stay in there.

    Nice quick job I am happy with it

    Cheers Jord
