    Default Timbecon 8" grinder on special at $129

    https://www.timbecon.com.au/sharpeni...-bench-grinder

    I just picked one up and here's some comments.

    The washers are good thick heavy units.

    The grey wheel appears to be #60 and the 40mm thick white wheel appears to be #100. Full marks for at least one wheel usable by woodies.

    The shafts are somewhat corroded but cleaned up OK.

    My Josco 8" wire wheel fouls the inner part of the guard so that has to come off.

    The shaft that takes the 40mm thick grind wheel isn't threaded that far down so some packing is needed under the nut for the wire wheel.

    On the other end I've mounted a hard felt buffing wheel. The wheel weights aren't that close but the unit spins smoothly.

    The white wheel doesn't have a recessed centre so may not be transferable to another grinder.

    It's rated at 550 w. Doesn't say whether that's input or output. If it's input it's on the weak side. My green Abbot and Ashby is rated at 900 w input & 600 w output.

    There's a couple of openings in the bottom of the case for mounting bolts or screws. They're recessed and so not so readily accessed as splayed feet.

    All up it looks to be good value.
    Cheers, Ern

    .
    If it's the only one quoted, on grinders it is usually the input power. It would be easy to check with an ammeter.

    Well I gave it a spin pressing some steel fairly hard against the wire wheel and the speed dropped only slightly, so good enough for me.

    Also checking the 6" hard felt buffing wheel projection - it's barely beyond the motor case and that'll make refreshing the edge of some knives a little awkward down the track. I may need to skew the face a little.
    Cheers, Ern

    I saw this. What is the size of the arbor?

    Ive seen a few and Im looking for a good tight 5/8" for my CBN's. All the ones Ive checked so far are decidedly sloppy.

    5/8".

    The 4 wheels have all been fairly snug. YMMV.

    looks like this is back on sale again (new link -- same product?) as well as its slow speed cousin

    which would you choose, and why?

    at the moment, the main purpose i have for a bench grinder is reshaping some tool blades, and for that alone, the slow speed one sounds plausibly better

    but, once i have a hypothetical grinder lying around, i'm probably gonna find other uses for it. like adding a buffing wheel for polishing painted/clearcoated projects?

    every time i start thinking "i need to get a grinder" i come back to these two, and then get hung up on not knowing enough to decide between them

    100% slow.

    I used to sharpen my lathe tools with a normal speed one and it scared the out shizzo of me.

    HSS needs to get to dull red before it's detempered.

    For carbon steel the variables that matter are technique and the wheel type.

    Even if it does reach red, or even orange, much of it will reharden upon cooling, too. Just in the air. It probably depends on the alloy, but m2 will suffer fairly little from being overheated like that, even though the edge left behind will be a whole spectrum of colors before it's honed off.

    How many speeds have you got ( mine is a 6-speed grinder)?
    Buy a felt wheel and a stick of green. Buff up all the kitchen cutlery and tools when nobody is looking.
    Say nothing. No evidence. Just wait for it. Good trick for favorite s/s pots, too.

    I am a little confused by Timbecoms specifications for the slow speed grinder.

    Its a pleasure to use out of the box.
    • 375W (1/2HP) 1400RPM induction motor designed for continuous running
    • Aluminium oxide (white) 60-grit 250 x 25mm wheel for shaping grinds
    • 25mm-wide wheel has adjustable 70 x 40mm toolrest
    • Aluminium oxide (white) 120-grit 250 x 40mm wheel for finder grinding
    • 40mm-wide wheel has adjustable 85 x 40mm toolrest
    • Crystal clear perspex eye-guards for better viewing of grinding when in use
    It says that it is an 8 inch (200mm) grinder, but that it has two white AlOx 10 inch wheels, presumably misprints?

    My view is that white AlOx wheels are the best choice of the relatively inexpensive wheels, work fast and a little less heat transfer to your tools, but as that is still an issue then I concur with WoodPixels recommendation of the slow speed grinder.

    But, if you are willing to upgrade to CBN wheels (around $200 each) then the heat transfer problem disappears and I would then go with the high speed grinder. But that is a big price jump!

    I bought one of these, but at full retail before the sale was on. I can confirm that the wheels are 200 mm dia, not 250. I also fitted mine with a Tormek bench grinder mounting kit. BGM-100. I've only ever used the 40mm 120 grit wheel for re-profiling before moving onto my Tormek grinder for final sharpening. I find that the AlOx quite adequate.

    The best of the friable wheels IME is the Norton SG ceramic (blue) wheel, #46. It's slow to clog, runs cool and lasts well.
