jmb Posted July 19, 2011 Report Share Posted July 19, 2011 I hate doing CGs. I would rather somebody beat me with a 2x4 than to file on CGs. Today I tried to come up with an easier and more predictable method, for me anyway. One of my problems is that no two sets turn out the same and only about half of them look presentable. In fact, I have long since refused to do CGs for people - PERIOD!!! I needed to prep a case for an upcoming project and the Shades of CGs Past started haunting me. I had ordered a 1/4" carbide end-mill with a 5 degree taper a while ago in preparation for trying this so I thought now would be as good a time as any. I first removed the tube and clamped the case onto my lug drilling fixture and milled the inside of both "ears" with the angled cutter: Then I centered the tube hole under the spindle: I then switched to a 5/16" cutter and "plunged" down through the center: I will have to admit that they turned out a lot better than they would have if I'd filed on 'em!

ubiquitous Posted July 19, 2011 Report Share Posted July 19, 2011 Looks good, J! Definitely simplifies the process of shaping those guards Link to comment Share on other sites More sharing options...
JoeyB Posted July 19, 2011 Report Share Posted July 19, 2011 Looks very good, and simplifies the job. I feel the same about crown guards as you do. That's why I like my 6542 and 6204 so much. I know I got the crown guards right on them both! Link to comment Share on other sites More sharing options...
woof* Posted July 19, 2011 Report Share Posted July 19, 2011 Amazing... yeah no kidding! I haven't even attempted modding cg's. It's obvious how it could go south fast and end up way worse than before you started. Have seen several watches for sale that have been ruined by people trying it. Now Jmb on the other hand...this makes total sense. I can see how much more the outcome will be consistant. Awesome idea! Link to comment Share on other sites More sharing options...
chiman12 Posted July 20, 2011 Report Share Posted July 20, 2011 J...what a great idea hold the case vertical without clamping the case in between the vise...minimizes damage. Link to comment Share on other sites More sharing options...
praetor Posted July 20, 2011 Report Share Posted July 20, 2011 I hate trimming crown guards too and I've only done it once. Good job on making the process much more efficient. I wish factories would get it right the first time (as if that's ever possible). what about trimming the profile of the crown guards though? though you'd still have to do that by hand Link to comment Share on other sites More sharing options...
jmb Posted July 20, 2011 Author Report Share Posted July 20, 2011 Unfortunately the outsides need to be done the "hard way" but I usually have a bit easier time with them. Link to comment Share on other sites More sharing options...
lloyd Posted July 20, 2011 Report Share Posted July 20, 2011 (edited) I see I am not the only one who loves power tools. I do the same thing with my mill. I also use a jig to locate the drill bit in line with the inner hole to drill the lugs. I do not have a tapered bit, so I tilt the case.

jmb Posted July 20, 2011 Author Report Share Posted July 20, 2011 I snagged the tapered cutter new off fleabay for under $20/shipped. It's solid carbide so it should last forever on these cases. I had originally bought it to attempt to repair some CGs that looked like I had filed on 'em but I chickened out since there would have been some welding and other stuff involved and it was a Yuki case so I was really scared of making it worse or ruining it. I think I may try to "stretch" the CG tips on my cartel 5513 once I get my Argon bottle re-filled... Link to comment Share on other sites More sharing options...
RWG Technical Posted July 20, 2011 Report Share Posted July 20, 2011 I still do the inner CG work with a #6 cut file, with a safe edge of course, takes a bit of time, maybe 20 minutes tops, but I can easily control the progress. For the outer CG work, well that's a different story, and is all done with tools, impossible to do by hand. Good results, but I wonder if you would save time by the hand filling method...

Ephry73 Posted August 22, 2011 Report Share Posted August 22, 2011 I originally thought of doing something like this, instead of thinking the outer parts too much. I think there is enough meat there to cut enough to sink the crown a mm into the case. Are you using Gen tubes for this JMB? E Link to comment Share on other sites More sharing options...
redwatch Posted August 22, 2011 Report Share Posted August 22, 2011 Very cool J! Nicely done! At least you have a consistent way to do the insides now!! Link to comment Share on other sites More sharing options...

Tribal Posted August 22, 2011 Report Share Posted August 22, 2011 I do this always by hand with a small fille inside. On Vintage ones I reshaped the outside too. But your way is nice and make it faster and easier to get good results. Link to comment Share on other sites More sharing options...

Ephry73 Posted August 26, 2011 Report Share Posted August 26, 2011 Question, how deep was the cut? I am concerned about the bezel being too close to the 703 crown. May be ok with the smaller 700. Thanks. E Link to comment Share on other sites More sharing options...
jmb Posted August 27, 2011 Author Report Share Posted August 27, 2011 I added no "depth" just cleaned up the insides of the CGs... Link to comment Share on other sites More sharing options...
