denimhead Posted June 24, 2013 Report Share Posted June 24, 2013 Greatly appreciate any imput into my dilema regarding this crown not fitting a cousins tube. The crown was bought as a 24-600 so i bought a 24-6000 tube from cousins. The crown inner is too wide to pass through the tube. Have I bought something else here guys?

denimhead Posted June 24, 2013 Author Report Share Posted June 24, 2013 So the tube doesnt fit the case? or does the crown not fit the tube? Hi M, The crown won't go through the tube. The inner diameter is too small, I wondered about fixing it in place with the spine tool then drilling out the middle. Not the best solution but I'm not happy about having to buy another Gen Crown Link to comment Share on other sites More sharing options...
denimhead Posted June 24, 2013 Author Report Share Posted June 24, 2013 If the gen doesnt fit then you have the wrong tube. The tubes are made exact gen specs. Ive used them on tons of builds and never had a problem. Contact Gary (clarks) and ask what type of tube you need and he'll let oyu know. Weird Mike as the tube is from Cousins here in the UK is Made to Gen spec as well. Is this a 24-600 or something else? Link to comment Share on other sites More sharing options...
1680 Posted June 24, 2013 Report Share Posted June 24, 2013 Which tube did you order? As far as I know the 24-6000 should have the teeth for the tube tool in the upper part of the tube for the bigger tube tool, the older tubes are like yours with the teeth down there. Maybe thats the reason... I have ordered a 24-6000 form cousins and it looked different, like I described it. Link to comment Share on other sites More sharing options...
freddy333 Posted June 24, 2013 Report Share Posted June 24, 2013 Yes, you have the correct tube. After the tube is installed in the case, you use a smoothing broach (available from most of the watch parts houses) to enlarge the hole to allow the crown to fit through Link to comment Share on other sites More sharing options...
automatico Posted June 24, 2013 Report Share Posted June 24, 2013 When broaching an old style case tube, be careful not to cut any more metal from inside the tube than needed for the crown to pass in and out of setting/winding position and set/wind the watch without binding. If you remove too much metal, the tube may break if you bump the crown on a door frame etc. A 'cutting broach' has splines for removing metal. A 'smoothing broach' has no splines, they are smooth for finishing jewel holes etc. No need to smooth broach a case tube unless it has rough spots or needs a very slight bit more clearance. It is good practice of course but very few go to the trouble. Link to comment Share on other sites More sharing options...
denimhead Posted June 25, 2013 Author Report Share Posted June 25, 2013 Thanks Guys, i thought i was going mad! invaluable information as per usual! Link to comment Share on other sites More sharing options...
bones Posted June 26, 2013 Report Share Posted June 26, 2013 yup, definitely need to broach the tube. I've had to do this recently for a 1665 build and also on the 700 crown tube I received from Phong. Broaches are pretty cheap from Cousins. Although I wouldn't use a smoothing broach, I would have thought a cutting broach better for the job? Link to comment Share on other sites More sharing options...
mymanmatt Posted June 27, 2013 Report Share Posted June 27, 2013 In guessing you have the wrong case tube. Yes you can brouche it and it may work. Be careful and don't take too much out. I have had many aftermarket case tubes Ive needed to do that to. Link to comment Share on other sites More sharing options...
bones Posted July 1, 2013 Report Share Posted July 1, 2013 No. it's the correct case tube. It just needs broached as the others have said. This is same as on a gen. Link to comment Share on other sites More sharing options...
quaresma7 Posted July 4, 2013 Report Share Posted July 4, 2013 Hi guys I take this thread for confirm if I have correct tube too.. Link to comment Share on other sites More sharing options...
automatico Posted July 4, 2013 Report Share Posted July 4, 2013 "Hi guys I take this thread for confirm if I have correct tube too.." This is a later style 'no broach' tube that requires no broaching. There is a splined wrench available to install it or maybe run it in the case with a crown.

1680 Posted July 4, 2013 Report Share Posted July 4, 2013 I wouldn't try to run screw in the tube with the crown, I tried it once and then had to remove the crown with a pair of pliers. Buy that tool, it's only about $35 and don't buy the cheap one you will regret it. Link to comment Share on other sites More sharing options...
freddy333 Posted July 4, 2013 Report Share Posted July 4, 2013 Always best to use the correct tool (most of the watch houses sell them) If you do not have the tube tool, a small, 3-sided hobby file (wedged inside the tube) can be used for install/removal.

quaresma7 Posted July 4, 2013 Report Share Posted July 4, 2013 The problem with my combo is that the crown don’t screw in properly. It doesn’t stop screwing in the tube. It seems like the crown or the tube’s thread is damaged, so now I don't know if the problem is in the thread of the gen crown or in the aftermarket tube. Now I don't know if the problem is in the thread of crown or in the thread of the tube... Link to comment Share on other sites More sharing options...
freddy333 Posted July 4, 2013 Report Share Posted July 4, 2013 If there is a problem with the threading of either part, it should be visible. If you do not see any damaged threads, then something else is wrong. Link to comment Share on other sites More sharing options...
denimhead Posted July 4, 2013 Author Report Share Posted July 4, 2013 Fitted mine with the spine tool then broached the inside out as Fred described to do. Works perfectly now and is happily living my Milgauss 6541 build Link to comment Share on other sites More sharing options...

freddy333 Posted July 5, 2013 Report Share Posted July 5, 2013 It looks gen, as best as I can tell with poor quality pics. If you post a good, clear macro pic of the rear (underside) of the crown, I can give you a more definite answer. Keep in mind that there are 3 different versions of the 6mm Twinlock & the inner spring/tube components of 2 of them had different diameters. The only way to know for sure if you have a matched pair is to see if they fit together. Link to comment Share on other sites More sharing options...
