    I could do with a few sets myself. Nice work on all the equipment too.
    Thanks Kryn

    Hi Kryn, it was off ebay. and yes the local price last sets I bought were more than that each. The ebay store is 'ozmestore1', he is actually here in Adelaide, at Birkenhead. I was about to get another 5 or 6 sets ( thought I would go down and pick up/ or use a mates courier service; pm me if you want.


    Thanks. I am well pleased to be back at it and making progress on rebuilds...

    Default more cold saw - initial assembly

    I pulled the catch tank off, and gave a final clean. Had removed it 2 years ago and cleaned all the 35+ years of grunge, so only the paint sanding dust and some cast iron fillings that had fallen down the drain hole in this recent round of prep needed to be removed. The tray is plastic, only slightly distorted, and held in place by two M6 SHCS.

    I haven't bothered to paint the underside, after I cleaned it up last.

    I cleaned up the ground surfaces, on the base table, underside of the rotating table, degree plate top and bottom, with green pads, and then turps and paper towels until clean, then a final acetone wipe. Preparation for a coating of Silber Gleit. Now I am not convinced this is going to be a good anti-cast-iron protection in this particular application - being flooded with coolant.

    I know Silber Gleit is good for dry woodworking machines, and it is MADE IN GERMANY so bound to be the ducks guts. (die Eingeweide der Ente). Although, the local packing doesn't actually state this ( ie no Made In Germany), and given the puck of SG sitting in an oversized plastic tub, and the English label, plus the amount of sticky SG on the outside/underside of the packaging ( not just mine, but all the ones on the shelf) I suspect this was either a local melt bulk/dispense and pack local effort, or locally brewed 'under license'. The original one comes in a metal tin in this size, and the ones on Amazon and Felder UK, Hafle AU sites, have the German labels. The one English label I could on the web also had 'Made In Germany'. Call me cynical.

    I cleaned up the degree plate on a sisal buff wheel and some grey compound ( Menzerna: also Made In Germany goodness). The degree plate is a bit pitted, so the compound attack was only superficial. It would be nice for this particular surface to be smooth and shiny, but I don't want to sand down the face for fear of losing definition in the scribed degree lines. The numbers were clearly punched by hand ( no jig methinks)

    A paint bleb I hadn't noticed, and a couple of touch up's required, but looking good-enuf I reckon at this stage.

    Default levelling castors

    Levelling castors

    grazing web space for some other castors I found these that I had wanted to get since I first became aware of them a couple of years ago. Found an Oz site that listed them. So ordered a set of levelling castors from a Melbourne castor supply joint on Thursday, arrived Friday; which was good. Ordered Foot Master GD-80F as displayed and imaged on their website. FootMaster is a South Korean mob (G-Dok Industries). Got a chinees substitute, not so good.

    I had been trying for a while to get some of these in Oz, the local branch of the national castor and wheels joint just looked at me blankly when I last asked about 8 months ago. Looks like the locals have cottoned on at last. I ordered by phone unfortunately.

    There is a myriad of chineesy knock offs, and usually labeled foot master in their adds, but stamped/cast with different names. Somewhere I got the impression that these things originated with FootMaster, and that FootMaster were manufactured in South Korea.

    Rated at 500Kg per castor, the orange thumbwheel screws the foot pad down lower than the wheel by 15mm. The default pad is antistatic NBR (nitrile rubber), as 'used in the automotive and aeronautical industry to make fuel and oil handling hoses, seals, grommets, and self-sealing fuel tanks'. There are PU options.

    These 500Kg ones are plate mounts (90x90x5mm), but there are centre mount types as well, Sizes range 50, 250, 500, 750, 1000 and 1500Kg per wheel. Prices from what I have gleaned, are relatively cheaper for the smaller load capacities. Alibabeee lists the Chinese knockoff, for c. $5-11 USD , min quantities can be as low as 100 units, So 25 sets could be about the same price as 2 sets locally. The substitute 'GD-80F' were $65 each (plus GST), which is about the same as ordinary cast iron centre PU 4" castors from most places locally. The wheel diameter is smaller though so ease of manoeuvrability will be different.

    But, stationary ( feet down) or mobile (wheels down) with a smaller footprint in one unit. Best of both worlds.

    I made two 300x90x8mm plates, and drilled and tapped for 8mm bolts. The plan is to probably cut the grinder bench down by 100mm or so, and the plates will sit against the underside of the lower rails. So just cross drilling for through bolts wasn't the go, as with the plates only projecting 10mm on three sides, bolt heads and washers and nuts would foul or not fit...


    I was planning to use these for my main benches, but thought I may as well fit them to the bench grinder bench to see what's what. I can get smaller load ones in due course and swap over.

    I have found the local Oz importer for the FootMasters : Blythe Enterprises in WA.

    This is a link to the Blyth page, there is a pdf specs sheet to download:

    Cold Saw through bolt

    When the first attempt to get the gear and shaft out of the casing was made ( 2 years ago), the nylon nut on the end of the 250mm SHCS was accessible but buried. And was very reluctant to budge. A few of us had a go, and the 3rd attempt applied some Oxy, after attempt two with propane didn't work. None of us could see the roll pin and that the nylon nut had been cross drilled. It got leaned on too hard and consequently sheared the nut off. Bugger.

    I got a 240mm SHCS originally as the )*&&*% local bolt mob would only sell me a quantity of TEN 250mm , at c. $35 AUD each, ( as they didn't carry that size and had to get them from their main branch interstate. They would sell me one 240mm though, which they also had to get from their main branch interstate. grrrrr.

    It wasn't really long enough, to make me feel secure about the nut, so I recently ordered a 250mm SHCS through fleeeabay for less than half the cost from the local supplier, and free postage. Oh, and it only took one week form O/S, as opposed to the two weeks from interstate for the first one.

    Put it in a lathe and cut a radiused bottom groove for the O-ring yesterday. Decided not to cross drill, I'll just use Loctite.
