    According to the web tread depth is 16mm and the centre can be re-cut to a depth of 10mm

    Regards Stephen

    That would be correct. Measured for you today….

    doesnt even register on the tyre gauge

    and where I got confused, side lugs are massive

  2. pitbulls are a snazzy looking tyre. But as you say, wide! there was a guy running them on his challenge truck many years ago and he seemed to do ok. 

    those radial treps would serve a purpose in getting you a taller tyre with more side wall but would you regret it later?

    another option to consider…

    Whilst their wheels are impressive they are not going to get me up the tracks at 7s......having said that nothing is getting me up there at the moment...... lol

    Regards Stephen 

    Ps how deep are the treads on treps  from new

    Regards Stephen 

     

     

     

     

     

    Couldn’t say how deep really….30-40mm maybe? Deep enough to class it as aggressive and make it stand out. The sidewall lugs are what makes them good though

    I'm not sure what I'm going to do with my Bridgeport to be honest, the electrical cabinet took a knock when I moved it from one workshop to another. I think the only thing that's bought it has been the main isolator switch which is simple enough to replace. I just haven't had time to re-assemble it all.

    Might be open to an offer on it - it was in good nick with a load of collets and various bits for it (no actual cutting tools but they're simple enough to source).

    Ed, if you want shot of it send me a dm with what you’re after for it and I’ll see what I can do

  5. I have been looking at mills. A friend sent me a link to a £600 Bridgebort(probably clapped out at that price) but I’m going to hold off buying new machines untill I have all the tooling I want neeed for the lathe. Top of the list for that at the moment is just tool holders for the quick change tool post. Ross very nicely saved aload of tooling from the skip for me so I have all the tool steel I need( @landroversforever if you wish to post evidence of a fair trade, feel free😂) …..so much so that it’s rendered the qctp useless as I only have 3 holders so have to change out anyway. Also need a 4 jaw…..I think the 3 jaw has been over tightened a lot as the jaws look a little bent….so new 3 jaw, spindle grinder or just get a 6 jaw….

    any way, all of that translates to no mill at the moment, would be very nice and is not off the cards but would rather get the axles done and the 110 out again.

     

     

    theres also a td5 and an LS sitting on stands that keep looking at me😂

  6. They both have their place. I find the grinder coming out a lot more but as Stephen says, the complex shapes and accessibility can’t really be beaten. Look at it like you have a gas axe but without the bottles. 
     

    also, rtech let you do monthly payments at 0%. It’s how I got my plasma and It diddnt particularly hurt

    You probably know, the mog and Landrover TRE's are different tapers, Mog is 7 degrees and Landrover is 11 degrees. In my mog thread ( page 53 ) I made an 11 degree tapered reamer as the only ones I could find at the time were the 7 degree ones.

    I have both, one bought and one home made, could post them down if you need them

    Regards Stephen

    Cheers mate, appreciate that. I will let you know beginning of next week👍

    you can , the trick is ... you need to know the spec's off the steel used ....and that's the difficult part to find ...

    Ah, I diddnt know that. I’m sure I can work something out though

     

    also. Tickled it with the grinder and it now fits. Still need to knock the corners off and make it look a bit more presentable 

    IMG_6796.thumb.jpeg.5ae8231a07b7209cfaf5e0cb502a83b3.jpeg

    the bracket is 20mm thick and the steering arm is 30mmx50. IMG_6799.thumb.jpeg.b3c79e88631789a357f904a3c854521a.jpeg

    Obviously the arm still needs shaping. And will be secured by 2 m16 bolts. Just trying to decide on weather to drill the tapered hole for the landrover TRE or a straight hole and use a rose joint. Could also use another mog TRE I guess

    Spendy, but not as bad as I thought it might be. I reckon the various places are just worried about the unknown hardness/treatments on the current shafts. Is there enough diameter on the original shafts? Or is the merc spline much smaller? 

    The minor diameter of the mog shafts is larger than the major diameter of the landrover shafts so there’s plenty of meat there. Getting to the stage where I might just weld them together so I can atleast test😂

     

    you are spot on though, the issue raised was the hardening. I’m not metallurgist but I was under the impression you could somewhat normalise steel and then re harden. 

     

    an example of re splined and new shafts

    @Soren Frimodts welded shaft which apparently held up well

    Non existent  at the moment.......

    usual life issues taking precedence, work, out of fettle etc

    Hoping to get back into it by the end of the month

    still trolling the net for a front axle for rear steering, contemplating having a shot at making my own

    Regards Stephen

    I know a guy local to me with a set for sale. Can work out a deal and go half’s if you want?

    How's the axles coming along @dangerous doug......

    Regards Stephen

    I’ve not really done anything with them mate. End of March is the big move around so I’ve been concentrating on getting stuff up on dollys or in a space where it won’t be in the way. The “horseshoe” for the steering arm is nearly done though. Just needs a final tickle with the grinder to pretty it up but I’m deliberately not doing it because I’ll get distracted and end up not having time to do the things that need doing……like all the lathe tooling and drill stuff I’ve acquired over the past few moths that’ll all need a storage solution😂


    By the end of April (most likely before) there will be a post worthy update though. I have all the material for the caliper brackets, trusses and spring mounts just staring at me.

    I think I have it all figured out…just the halfshafts that are being problematic as no one can cut splines or if they can, they don’t want to machine down the shafts and re cut splines.

  12. It’s up and running! 
     

    I diddnt go down the phase converter route in the end, I called transwave and had a long chat with a man who actually knew what he was talking about and he basically said the only way you can run the m300 to its full range was with a rotary converter as the statics won’t cope with the top speed. I really diddnt want to dump all that cash into it right now so went back to square one and got a new VFD. This time round it’s a Parker drive AC10. Another drive I have a little experience with and they seem to be ok. The trade off has become clear very fast though. The torque isn’t there so I am limited to fairly small cuts. But it’s fine, it works!

     

    my YY control cable diddnt arrive until I got to the workshop so the control circuit was all SY cable which got confusing at times with everything being the same 3 colours.

     Being curious to the next guy incase it’s actually wired to 3 phase again

    IMG_6519.thumb.jpeg.db706e260a901c1f257dcd94380bad08.jpeg

    Diddnt really take many photos from here on as I just wanted to play. Did make a new top nut for the tool post so I can go for the 2 leaver set up others do.

    not sure if this is just a thing you have to do or if something else is off but I had to put a dti on everything I I put in the chuck as the runout was insane.

    IMG_6521.thumb.jpeg.06e6b031a279c0e2426ce24f2f009d69.jpeg

     

    is what it is and dealt with it. Nut is done complete with chamfers(because were civilised people) and I’ll be putting a handle on it tomorrow. Need to work on surface finish. I’m assuming it’s because I’m going a bit slow and using carbide inserts at the moment 

    IMG_6535.thumb.jpeg.aaaa193fbf0a33351c069db2b6fbf01c.jpeg

    bot sure if I’m happy with the height, mite take a bit off the top tomorrow.

    IMG_6534.thumb.jpeg.beb67951d27236fa3d52dad841de6b19.jpeg

    All in all a nice little project. I’ve ordered a little bearing to go under it which I think will make a difference and it’ll protect the nut at the top. And possibly give more clamping force?

     

     

    Little message I left for the next guy at work….thought it may be relevant here too😂

    Some(most?) 3 phase motors can be wired star for 415v or delta for 230v. It just depends how you connect the windings. As 3 phase mains is 415v across phases, ie 230v from each phase to neutral, most motors come wired star. But for a VFD or converter you may, but not necessarily, have to change to delta, ie 230v depends on the device. That said, if you want to just run the motor at a single speed, it's probably simplest to just get a new single phase motor.

    I was under the impression that all ac motors were basically 3 phase motors with a start capacitor between W1 and W2 known as a steinmetz connection (found the correct spelling).  It works but you Lose 1/3 of the torque….im not running an industrial work shop here so this isn’t a big deal and I can do it down stream of the motor. This is also what I suspect those DPS boxes are.

    IMG_6455.webp.53c564c40331762fbb46aa71b187afb2.webp

    I have priced this up and it’s going to be about £100 for mid range parts but we shall see what happens as I’m talking to a man about a phase converter now…..but that is basically the above drawing with more of the same in it.

     

    im happy to be wrong about the single phase motor though. I havnt really worked on them and have never been in one to take a look, just upstream fault finding to make it work

    Am aware of the noise from the rotary converters which is why I’m looking at the static ones. 
     

    this is an alternative

    https://www.ebay.co.uk/itm/283812247889?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=jrumxrpurbc&sssrc=4429486&ssuid=WZUdkjFXQ3K&var=&widget_ver=artemis&media=COPY

     

    it says it’s digital somehow but by the description I suspect that this is just a capacitor in a fancy box using phase shift

    Did a bit more digging and this is only good for a 230v motor

     

    did stumble across this though

    I also looked at getting 3 phase in direct, bearing in mind the sub station is less than 10m from my workshop, I got western power down to have a look, the engineer was very nice and made an immediate estimate of about £7500 to 10000 and that just to run the cable to my property, work on my side would be down to me. He offered a full formal quote but didn't think it would change much so it would have been a waste of time. He did mention that some one else he had spoken with ended up getting a second hand 3 phase generator and running that but since I live on an estate with close neighbours that wasn't a solution that would have made me popular, guess it depends where peoples workshops are.

    Much like a trailer, vehicle lift, tig welder or lathe…..you’re always popular if you have a 3phase generator😂
