Konrad Piston

[bassmannate]

I have an ebonite Konrad and the piston is REALLY hard to move. I cleaned the whole pen when I got it and greased the piston with silicone grease as suggested by people here as well as Nathan.

 

Any ideas on getting it moving smoothly? it's has been the only issue I've had other than it writing dry last night. I think at was a paper issue though as I've gone through half a fill without that problem.

Hmm, you greased both the piston mechanism itself as well as the rubber seal around the moving part in the ink chamber? Weird that it'd still be difficult to turn. I'd recommend that you apply a thin layer of grease over anything that seems even remotely related to the piston mech, just to be safe. Or, if you want to be conservative, just take a look at the assembly and see whether you missed anything important. It's also possible that some debris might have gotten stuck, so you'll want to take it apart quite thoroughly if you haven't already done so.

 

 

Cheers, and best of luck!

Alright. I'll grease it down good next time I take it apart. It's strange because it's hard to get moving, but once I get it moving, it moves relatively easily.

Off the top of my head: perhaps you screw it in place too tightly? IIRC, it utilizes the force of friction against the end of the barrel to stay in place.

Nope, it's super tight at any point in the barrel. I screwed it in a bit earlier since I only have a half fill and just tried moving it again. Hard to get moving but moves easier once I break it free.

Mine is/was the same when it was new. It can still be a little sticky, but I haven't noticed it being that hard to budge like it was in the beginning. I've had the piston out multiple times and re-greased it. Using a lot of grease did NOT help, BTW. I used a paper towel to wipe up the excess grease in the barrel, and then I greased just the piston head.

Some of mine are a little tight to start. This is either when they're new or when they haven't been used for a while. They seem to loosen up upon use.

 

If everything has been greased, just keep using it and filling it.

[JoolsH]

Yeah. Had the same problem. Mine got to the point where it jammed and no longer works. I'm looking to replace the piston mechanism.

Mine gotten stuck and broke. Less grease is better but the piston tube is not formed very round so it's a tight fit on some places.
