    Default Drill Press Table Refurbishment ( Or A Recipe For Disaster? )

    Early last week I acquired yet another drill press, a late model 12 speed Tough. The table is, as expected, not perfect, and has a few small holes that require plugging. What I would like to do is clean up the face of the table then plug the holes and give the table another light facing cut. I don't have a lathe large enough to accommodate the table's 292mm diameter but the little Hercus mill might just cope. Having the table dangling so far from the chuck is probably a touch too optimistic so I was thinking that a dead centre mounted on a post that is in turn mounted onto the Y feed bracket might just work. The through hole in the table's spigot is a bit rough requiring a careful rebore which I would do on the other mill.

    What do you reckon? Any suggestions?

    Bob.

    Just wondering whether it may be a strategic move to make up a proper mount for that table onto your Hercus (that is, without the 3 jaw chuck). You would not turn things that size often but it may be a worthwhile capability to have if you can get the faceplate back against the column.

    Hi Bob, good thinking l reckon, sometimes you just have to have a crack at it to know.
    Low revs and a light cut that cast iron should peel off nicely, maybe take a light skim off out near the periphery first
    just to see if you are going to get any chatter.
    Are you thinking HSS for the tool ?

    cheers, shed

    Hi Bob,
    If you can remove the spigot then turn up a short spigot to face the table you overcome the overhang. It all depends on how easy it is to remove the existing spigot.
    Cheers,

    Hi Bob,

    Looks good. The only area of concern will be when cutting at the outer periphery. Not sure how rigid that table is but there may be a chance of deflection of the drill table. Definitely use HSS, make sure it's nice and honed, low speed and nice light cuts. Should come up a treat!

    Cheers,

    Simon

    Michael and Shed,

    Thank you for your replies and suggestions. Alan "C-47" has generously offered me the services of his 13" swing Colchester which will save me a lot of work and anxiety.

    Further to your suggestions though, I had thought of opening the spigot's bore out to 1". That would enable the table to be mounted on either the 13's 30 taper saw arbor or the Hercus' 3 Morse arbor. The 13 has the advantage of power feed but lacks the facility to mount an external support as suggested in my pretend setup. I'd use HSS because my dainty carbide wouldn't cope too well with the slots.

    Young Rod and Simon,

    I was laboriously one finger typing my reply to Michael and Shed. The spigot is integrally cast and while I could hack some or all of it off, I reckon it would be a shame to do so. The table is a pretty robust thing. It is 10mm thick.

    What's the story BT! Not a Swiss drill press

    It will be Swiss standard after you finish with it.

    Hi BT,
    I would go with the bigger lathe, the set ups you have shown would not be rigid enough, it would sing like a canary and chatter. Even with a big lathe you will need a very sharp tool and low speed. When I turned up the table for my Camel Back drill rebuild which had a 15" diameter table I used a mates 18" lathe and had to drop down to a low speed to avoid chatter.

    Swiss! You mean a Fehlmann Piers. Something like this? https://www.youtube.com/watch?v=nQLwBTgfLyI

    Probably not for 165 bucks!!!

    Hi Bob,

    You would be able to do that job with a tool post grinder, rather than trying to machine it with a HSS lathe tool.

    He could, but I don't think Alan "C-47" would like that idea!!!
