mnshooter Posted December 16, 2015 Report Share Posted December 16, 2015 (edited) As it's obvious from the photos that they are not the same, I'm not sure what you're asking. But, the one from Keepshooting is the one you want. Edited December 16, 2015 by mnshooter Link to comment Share on other sites More sharing options...
Guest title ii Posted December 16, 2015 Report Share Posted December 16, 2015 Does anyone have any experience with the ones for sale on gunbroker? While the photos look different wasn't this the company that had a trademark issue? Basically I want to know if the ones for sale on GB are worth it?

Chief762 Posted December 16, 2015 Report Share Posted December 16, 2015 I believe they are both the Taiwanese repro Crosby drums. That said, I got mine from Keep Shooting. They come ungreased, but once serviced up, they work great. Stay away from the modern Auto Ordnance ones, though. They suck.Chief762 Link to comment Share on other sites More sharing options...
m60mgman Posted December 16, 2015 Report Share Posted December 16, 2015 I got one from Numrich and it appears to be like the Crosby copy but unmarked, made in Taiwan. I had to tweak the bullet guide inside so it wouldn't rub the rotor. I like my Bridgeport better, of course. The metal is stiffer and it's made in the USA, about 70 years ago. Function? I'll be able to comment on when my 21 comes in. Link to comment Share on other sites More sharing options...
Guest title ii Posted December 16, 2015 Report Share Posted December 16, 2015 How easy was it to tweak the bullet guide inside so it wouldn't rub the rotor? Perhaps do you have photos of the before and after?Is this a job for the drum specialist or can one do it with basic tools? Link to comment Share on other sites More sharing options...
Uncle Dudley Posted December 17, 2015 Report Share Posted December 17, 2015 (edited) To "tweak the bullet guide rails", just slide a cartridge along the rails and if you feel a slightly tight spot, you can usually move or wiggle the cartridge side to side and slightly move the rail for clearance. I don't think there would be any interference with the rotor, usually it's a tight spot in the rails. It's really that simple for a minor tight spot. My "Taiwan Crosby" drums were fine, but I did have some tweaking to do on the West Hurley "L" drum I bought. I much prefer the quality of the Taiwan Crosby drum. I have 6 of the Taiwan drums, 5 work perfect and the 6th is still in the box, unfired. U D Edited December 17, 2015 by Uncle Dudley Link to comment Share on other sites More sharing options...
MG08 Posted December 17, 2015 Report Share Posted December 17, 2015 I picked up one of the new "Crosby" marked drums, found it for $106 delivered. Came in the box. Seems to work just fine, I have not really wrung it out, but it fits and shoots. I am using it in WWII FA guns. Link to comment Share on other sites More sharing options...

It's really a ramp to get the cartridge to the opening. The rotor had some wobble and the rub was significant. I slightly squished it carefully with some flat tipped pliers. You have to be careful. It did the trick and no more rubbing is happening. Link to comment Share on other sites More sharing options...

Guest title ii Posted December 20, 2015 Report Share Posted December 20, 2015 Ok what kind of grease is recommended? Something that can be purchased at the local hardware store? Thanks Link to comment Share on other sites More sharing options...
mnshooter Posted December 21, 2015 Report Share Posted December 21, 2015 (edited) Ok what kind of grease is recommended? Something that can be purchased at the local hardware store? ThanksThe tricky part is getting the grease into the right places. There is a greasing tool just for that. Sometimes they are offered for sale on this board; they work with a standard grease gun. A couple of years back Deerslayer Dan was loaning his greasing tool in exchange for a board donation. Not sure if he is still doing that, but you could ask him. Dan would also be able to tell you what grease to use. Edited December 21, 2015 by mnshooter Link to comment Share on other sites More sharing options...

darrylta Posted December 22, 2015 Report Share Posted December 22, 2015 (edited) I made one out a simple 1" steel pipe plug. Drilled and tapped the side fora zerk fitting and ground a flat spot on the top of plug for C clamp bearingand used some leather scraps for gaskets All in all the cost was around 5 bucks. What I discovered the hard way, is the route the grease travels is between the body of therotor and the spindle. If your doing a vintage drum, this interface is full of hardenedgrime and grit that greatly impedes the grease flow. It's always best to clean this areaand soak it with penetrating oil before attempting to grease it.

buzz Posted December 22, 2015 Report Share Posted December 22, 2015 I made a grease fitting out of a 1" steel pipe plug as well I used the side of a grinding wheel to make the face of the cap nice and flat so it would get a good seal with the gasket Instead of drilling and tapping for the grease fitting, I just drilled a hole slightly larger than the thread and glued the fitting in place with JB Weld. Works fine Link to comment Share on other sites More sharing options...
