    If for any reason you don’t get this I’d be interested in saving it from scrap.
    Even just the base casting.
    I don’t have a library as extensive as Matty but have a few cattle dogs mainly Wadkin.
    I have a couple a Wadkin machines in my shed here in Sydney.

    My first reaction-“ bloody hell that will be very heavy”
    like all Robinson machines, they certainly didn’t skimp on the iron.

    I reckon you’re right. I’m not looking forward to moving it.

    Somewhere around 7 years back Myself and Matty did a road trip to the west of Sydney to pick up some machinery .
    I'm sure a thread was posted of that trip here somewhere, I cant find it .
    Anyway, We picked up some Wadkin stuff ( PK and CD I think ) and sitting amongst one of the sellers outdoor stash of rusty machines was a Robinson saw which looks to be the same type. I thought it was some sort of combination machine until studying My pic after seeing this thread and realized the boring table is a bolt on later addition .
    We left it sitting there , to far to go and a big enough load as it was. We spoke of the Robinson a few times after that , saying what a nice thing it was and how it'd be nice to have saved even if it was just to be a garden ornament .
    It may still be sitting out there with the rain dripping off it still ?

    Edit
    Looking closer the saw I just noticed a difference than the one in my pics. The table has an interesting tilt mechanism that tilts the table on the left side of the blade only . That's pretty cool ! Never seen a one sided way like that before .The off cut would just drop away back to the horizontal right side safely I think . Not slide down against the blade wanting to fly back at you .

    I Remember now Rob, we should of grabbed all those machines !
    Your memory is amazing Rob, that saw is identical, the horizontal boring table is not original and a later edition.

    Nice story and pics Rob.
    I reckon you & Matty should have got it too.

    I picked it up today. Well I didn’t actually pick it up, it’s waaaaay to heavy for that. But we (5 of us) dragged it out of a garage and to the back of my pantech. Managed to get it onto the tail lift and then up into the truck. The tail lift has a 600 kg capacity but it struggled to pull it up. It’s very heavy for a little saw.

    It seems to be the exact model in you last pic Rob. TR Saw.
    It’s in remarkably good condition. Everything works. No rust really, only fine top rust. All the screws are still wet with oil and turn easily, even nicely. The brass bush bearings have absolutely no play and the bearing in the motor roll on for ages after just a small spin. Really surprising!

    Anyway, pics is what you want!

    Regards
    Pete.

    I see in Matty's catalogue pic that the machine will take any blade up to 15". The existing blade looks as though it might be smaller. I also wonder if some adjustment is necessary on the pulleys depending on blade size to give an optimum tip speed.

    Hi Paul

    Yes, the current blade is about 12”.
    I wondered about the blade tip speed on bigger blades too.
    I don’t know too much about calculating and matching motor, blade and pulley sizes but I guess I’m going to learn.
    I need to rewire the motor first and see if it goes. I suspect it will. Then I’ll draw on forum members expertise to guide me further.

    This resto project will not be a quick one. SWMBO wants me to build a new bed, bedhead and bedside tables first.
    Maybe I can sneakily work on it while the glue is drying[emoji848]

    Best regards to you.

    Pete.

    That blade is a little bigger than I thought from the pix so you might not have to make any adjustment to the pulley. I only mentioned it because the big limitation on table saws is the diameter of the blade. I had surmised it might have only been a 10" blade, but difficult to gauge from the pix.

    The difference between pulleys is a ratio. The issue I am not sure of is the ideal speed of a tungsten tipped blade compared to the type of blade for which your saw was designed (ie HSS). I would expect, but don't know, that a tungsten tipped blade needs to go slightly faster. If that is the case the speed issue will take care of itself using the existing set up. However.....this does assume tungsten tipped blades either can or need to go faster. It also assumes the current set up with pulleys is correct for that blade you have.

    possibly other people can contribute some information here.

    Regards
    Paul

    Pete and Paul, l can see the motor is a 5 hp Swedish made Asea. Plenty of torque there.
    It reads 1420 rpm and the pulley ratio looks to be 1:2 so basically doubling the speed at the saw shaft.
    Traditionally rip saws or break down saws ran at low rpm as heat was something to be avoided on the old carbon steel blades. Pete your robinson saw would of at one stage been part of a line shaft, so speed at the main shaft would of been around 900 Rpm, not hughly fast.
    That said depending on what work you will be doing, a tct blade will cut cleaner with more rpm ..

    Hey Pete, wondering what the diameter of the pulley on the motor is ?

    When measuring a pulley, should I measure the diameter at the base of the V or the overall diameter?

    Thanks

    the old man just used to measure the overall diameter, as long as you measure the same on both should be close enough give or take a few RPM's
