    Annealing bandsaw welds

    We are welding bands together for our sawmill with an old ideal resistance welder, the bands are 1-1/4" and .045" thick. We have experimented for hours with settings and think we are getting a pretty uniform weld, even build up, no porosity or inclusions in the grinded join, shiney steel on both...

    C3 bearings for lathe spindle

    Hopefully just a quick question, I have an old union graduate wood lathe that I've been coming back to again and again over the years, chasing a chattering gremlin. I machined a new spindle for it when I got it and have done so again all these years later with my machining skills having...

    Band welder tips

    I'm trying to get an old ideal bs1 band welder I've picked up going and so far haven't had much luck. I managed to weld and anneal one band rather nicely when playing around before looking at instructions but since haven't even got close. I've figured out what all the settings do, have set the...

    Danfoss hydraulic orbital motor

    I've got a few danfoss oms 80 motors, geroler type. I came into one cheap from a guy who had a bunch more so I bought 3 of them thinking they'd be handy. Have come to a project needing a motor so I plumbed one up today on the bench and didn't realise what I was looking at until seeing the...

    Die angle for bending attachment

    Hi guys, I started to wade through the information online about springback and K factors but figured I'm going to get an easy answer here I hope you don't mind me being lazy. I'm going to build a simple sheet bending unit for my press. Consisting of a V die, pillars either end, and springs...

    Looking for manual for John ford 2s turret mill

    Hi all, Hoping to track down a manual for the above machine, printed on it is just "2s" next to model, and 1993. Hoping to help out an older friend who doesn't use internet. Google doesn't seem to know much about the 2s, and a keyword search here returned no luck. He is having trouble working...

    Hydraulic press aeration

    Hi guys just got done putting together a press and plumbed it today, left it running a few minutes and next thing foamy oil is erupting out of the filler neck so I'm getting a heap of air in my circuit somehow, watching the return line it behaves like a garden hose coughing it's air out when...

    Seco inserts or ebay rip-off

    Probably doesn't need much more explanation than what's in the title. Newbie here still cutting my teeth... I bought a pack of TCMT seco inserts from ebay after being told they were the brand to buy. Much cheaper than in NZ here (as everything is). But now I'm wondering if I've been had. Maybe...

    Phase loss error when motor stalled

    Hi guys just a quick question, Is it normal for a stalled motor to produce a 'PHL' error, which is phase loss according to the manual, or have I got something weird going on here? It's a .75kW 3ph motor in a wood lathe, 1.5kW delta VFD-B drive. I reset it and it carries on fine but seems to be...

    two pots for one VFD

    I have a VFD controlling a 3 phase motor that I wish to control from two seperate panels depending on which side of the lathe I'm using. On the main side is start/stop momentary push buttons, a 2-pos fwd/rev switch, and a pot. On the other side is start/stop and a pot. Ideally I'd like to set...

    Rough spot in centre when facing

    Just wondering if I'm doing something wrong or if there are any tricks to get the whole face of a shaft finished nicely. I assume where the surface fpm goes below a certain speed the tool starts rubbing. I have tried varying the cut depth from .05mm to .5mm, varying cross feed speed, and...

    VFD output voltage

    Hi guys, Just a quick question which is probably going to be stupid but the output voltage in the specs on these VFDs whether they be Hitachi or china-noname, is it the voltage per phase i.e. what you'd measure between each motor terminal and neutral or the delta wired motor voltage (if I've...

    Wood lathe runout

    I recently got hold of an old union graduate lathe for a pretty good price. Here in NZ I couldn't find anything to fit the 6TPI thread. I didn't like the idea of an adapter so I knocked the spindle out and took it down to a friends shop and got him to machine a new thread so that one of the nova...
