Mec 650 Questions
Hi,
Picked up a used, older MEC 650 on the weekend for $100. Stripped it down for an overdo cleaning. Reassembled it today and encountered some minor problems you could help me resolve. Likely some adjustments.
First, the charging bar will only lock back manually. If not locked manually the bar will go back and forth with each up & down stroke. This means it will drop powder on an upstroke. What needs to be done?
A primer tube assembly was mounted on the press. The removable tube was a flimsy, bent cafe` rod. I can make or buy another tube but it seems it would be tedious to pick up primers one at a time. The press also came with a tray type primer feeder. A check of the schematic on the MEC website the for the 650N shows I'd need a couple of missing parts including the chain. Will the primer tray work on the older version?
The MEC site also states that the 650N won't size the hulls and needs to be done separately. The older version is threaded for a sizer tube. However, the sizer tube and primer units cannot be used at the same time. Does the older 650 version provide an option to either size hulls and manually feed the primers or don't resize and uses a primer feeded?
At the very bottom of the tube fed primer system is a wire spring. Does the lower end of the spring belong in the slot in the tube? Seems it belongs there but would stop the primers from coming out.
Thanks
Jim

Assuming you got everything re-assembled correctly; it sounds like you might have to slightly bend the tab that holds and releases the actuator rod. It should be between the rammer tube clamp and spring. A very slight up or down tweaking of it makes a big difference as to whether the bar lock works correctly or not. The old tube feed systems work fine but require a tray accessory to fill the tubes. Usually one would fill all the tubes he had before undertaking a loading operation. The bottom of the drop tube had a spring activated tip that was tripped by the indent ball washer to allow one primer at a time to fall into the priming station. The tray type priming assemblies will work with the older 650's and were intended as an upgrade. As you noticed you will need the chain and a clip on bracket that mounts on the depriming foot. They require a different bracket for mounting and adjustment but I believe the old tube bracket might could be modified. None of the 650's can resize. 0 -

Later I found a segment on the Mec Website that at least the older 650 can resize like a single stage press. All that's need is to remove the primer feeder and screw in a sizer body with the correct guage ring from a single stage press over the de-primer shaft. 0
