    Stripping down a Startrite Mercury - The Good, The Bad....

    Here's a little bit of an update. I got the replacement bearings for the quill yesterday. They were 5/8" I/D, so a little on the unusual side - paid the extra couple of pounds for some Swiss ones, which are butter smooth. Now that the paint on the frame was dry, I reassembled the quill and...

    Stripping down a Startrite Mercury - The Good, The Bad....

    Hi Philip Thanks for your reply. Looks like yours is in good nick now. There appears to be a minor design change over the years with these drills. Perhaps it’s only one small thing, but it’s obvious from the detailing of the front belt guard (that has the startrite badge)- the slightly older...

    Stripping down a Startrite Mercury - The Good, The Bad....

    Evening all, Now that I've the chuck off (at last) I spent a few hours today stripping down the machine. Aside from the weight of the thing it wasn't too tricky - with the exception of a few bearings, see below. Many of the bolts were reminiscent of Goldilocks, i.e. someone's been messing...

    How to remove the chuck? Startrite Mercury (different!)

    Thanks for the info. Yes, that's why I got this thing - to renovate. I've used some not-so-cheap modern drills a few years ago and they were garbage, compared with one of these that we had when I worked at University. Anyway, rather Than continue this post, I've started another one (with a...

    How to remove the chuck? Startrite Mercury (different!)

    Evening all, Thanks again for your help - I'll have a shufties at work for some of those bars you refer to. I've had another look at the drill this evening. My aim in the near term is to get an understanding of what bits and bobs it'll need. Here's the first 2 that I'd be grateful for your...

    How to remove the chuck? Startrite Mercury (different!)

    Trevanion- yes I had it running yesterday. Is seemed ok. The motor’s pulley was wobbling all over the shop - you can see when turning it by hand it’s not on straight. Oddly the run out measured on a drill bit (which, of course may be bent) was greater than 0.025mm.

    How to remove the chuck? Startrite Mercury (different!)

    (dunno why the images have gone a little mad!) Evening all, Thanks again for the replies. Turns out whilst there is a hole in the chuck, there's not in the taper. Though, is this a problem?? It does look different to the manual: As you say, the run out is small (tolerable?). I think...

    How to remove the chuck? Startrite Mercury (different!)

    PS I noticed the hole in the base of the chuck after I’d removed it. Guess as it came out easily the retaining bolt had taken a hiatus

    How to remove the chuck? Startrite Mercury (different!)

    Hi Philip Thanks for your offer - yes, I would be very keen to see your photos. If posting them is problematic I’ll suss out how to share my email address. Anyway, I’ve now got it off. I used a good squirt of gt85 and applied a little force with a pair of large (30mm jaws, I think) spanner’s...

    How to remove the chuck? Startrite Mercury (different!)

    Thanks for the great (and amazingly prompt) replies folks! :D I've never used a pair of those wedges before. Quick shufties on Google shows them as costing under a tenner (hopefully I'm looking at the right thing), so happy with that. I've taken a quick closeup of the quill with a rule...

    How to remove the chuck? Startrite Mercury (different!)

    Hi Matt Ok, thanks. Does the chuck just push onto the taper then - held in place, like a Morse taper by friction?? Cheers Phill

    How to remove the chuck? Startrite Mercury (different!)

    Hello all. This is my first post here, so apologies if it's in the wrong place. I've recently acquired a Startrite Mercury. Other than it missing the belt guard (lid at the top) - which is replaced by an ad-hoc aluminium thing, and 1 knurled nut, it seems to be pretty much in tact and un...
