I have to replace a damaged bottle cap that powder and shot bottle screw into on an older MEC 650 and wondered are they really just soldered on with actual solder?
I have multiple options to un-solder the damaged cap and either re-solder or more likely JB Weld a new cap on after I drill a hole in the new cap of the correct size. If the cap is more brazed than soldered I'll just hit it with a grinder and take the cap down to clean metal to attach the new one. De-soldering would be less likely to damage underlying part than a grinder but if it's not really a solder it would be a waste time to try and remove it with heat. Besides hotter than the devil's door knob out in the garage right now.
I'm also looking for someone that has the MEC 12 gauge sizing ring that goes inside a tube on some of the MEC presses. I need to know the outside diameter and thickness to see if it might fit a Pacific DL-105
