    Default Needing Some For A Small Surface Grinder Job in Melbourne

    I am in the process of restoring an old Waldown press here. I want to have the table and the flat surface on the foot surface ground and I am wondering if anyone would be interested in taking on the job.

    I am happy to reimburse you for your time and effort.

    You would need a massive surface grinder to do that job me thinks...

    Hi mate,

    I'm quite happy for you to come around and see what we can achieve using my sg. As RC says, thats a very big work envelope you would need. My sg can do 450mm x 200mm which would cover maybe half of that. I'm not sure, maybe you could do it in two passes.

    See what others think but the offer is there. No cost involved. I'm near Hastings.

    Thumb,

    Using a shaper might be an alternate and maybe more appropriate means of refurbishing the base and table. My 10" Douglas was a touch too small to tackle the Waldown base but it did a great job in my opinion on the smaller Tough drill's base. http://www.woodworkforums.com/attach...1&d=1335577198

    A number of forum members have shapers of a size that would make easy work of the table and base.

    You can plug the holes in the table. I used cast iron - http://www.woodworkforums.com/showth...78#post1502378 Others have used epoxy mixed with cast iron dust to good effect also.

    Hi Simon - thanks for the offer. When I said small I sort of meant not many pieces. I did not consider what effect the size of the pieces would have. I am in Coburg and Hastings is a long way for a man with no car (going for my licence in a month) and who depends on others to move big things around. However if no one closer can be found then we will have to find a way to take you up on your offer.

    Bob thanks for the link. I was leaning toward filling the holes with mild steel rod as it would be easy to get, however cast iron would be nicer. Does Interlloy sell small section of 4E? I might have to commission someone to turn down some plugs for me.

    Is
    Loctite heat resistant? As I am getting the drill press power coated. I was thinking of welding the rod in place.

    Bob first time I ever heard of a shaper, interesting tool.


    Its like a cross between a surface grinder and a scrapping plane.

    I was thinking of using a flap abrasive wheel to grind the deeper dings on the foot down. So that the final finishing would be a quick few passes. Good OR bad Ideas?

    Bob I will look at my irregular hole in the middle of the table to see if it could be milled out nice and clean like you did.

    I have used metal lathes and milling machines at University but I do not have access to such thing these days.

    Bad idea, unless you were good at grinding, as you'd grind hollows into it everywhere, some might be deeper than the ding, making more work.

    Default Waldown restore

    Several quick questions. Does the table rotate around its centre? Is the column mount on the foot casting in the same plane as the main flat surface? If so, it should be possible for someone with a larger lathe to swing each piece in a 4 jaw chuck and take a facing cut on each, perhaps after the unwanted holes have been plugged. Regards,
    Combustor.

    G'day Thumb,
    You are welcome to bring it around and I can have a crack at fly cutting it for you. I'm in Fawkner, I could even swing around and pick you up if necessary. Regarding the holes, some kneed-it epoxy metal will do the job, the fix won't be invisible but it'll be functional.
    Cheers,
    Greg.

    I have the following holes sizes - one @ 12mm, 6 @ 6mm, one at 28mm. I am happy to pay for time and postage if you are happy to part with some wrought iron.

    All my reading says that powder coating is more durable and less prone to chipping then paint.

    OK I wil not use the angle grinder.

    Greg

    That would be great especially the pick up, are you still happy with a case of beer?

    I will have to check.

    G'day Thumb,
    If you can get the CI from Kryn then I can machine the plugs as well. Not sure how hot things get when powder coating, it might be better to plug your holes and machine the table after you get it done. For what it's worth, I'd go with painting rather than powder coat, a decent enamel is plenty strong enough for machine tools. The other thing is unless the base has some really bad damage there's probably no need to machine it but I'm happy to do it if you want. A case of Little Creatures Pale Ale sounds fair.
    Cheers,
    Greg.

    No worries. Bob's idea of using a shaper is probably the best idea but fly cutting will also work well too.

    Sounds like you have a plan!

    Greg it is a deal.

    I will try to get the RI.

    Power Coating goes to 220º.

    Most glues fail below that temperature.

    So that is why I am leaning toward welding the RI in.

    The damage to the base is minor, but I have come this far so I might as well go all out.

    I will be in touch.

    What type of machine will you attempt to flycut these pieces on Greg?

    I'll be using a Thiel Duplex 158, swinging a UPA-4 boring head as a fly cutter.
    Making a proper fly cutter is on my to do list but the boring head works fine with small cuts so it's a fair way down.
    Cheers,
    Greg.
