Polishing parts

Hello all, I had a question about polishing select parts on my 550. I have heard and seen guys polishing the bottom inside of the powder measure for easier powder flow. Has anyone polished either the powder bars or the primer feed bar for easier operation? I have not polished any parts on my 550 and was just wondering about it. Input?

RE: Polishing parts

Marginal results for the effort expended regarding polishing the powder measure.

Get the same results applying a couple coats of a good car wax to the bottom of the powder funnel and buffing it. Same with the powder slide.

As for the primer slide, I'm using a polished extended steel plate that has a roller bearing attached to it. Price is a bit on the high side but priming is incredibly smooth now. Search on eBay for it, I liked it so much that I have it for both 550's. Not affiliated with that person, just a very satisfied customer. I did have to adjust primer ram height which was not in his instructions.

I am trying out DuPont Teflon Dry Lube for the primer slide and it seems to work well. Apply it and wipe it down lightly. I do this after every 3-500 rounds as the press needs a cleaning by then. No sticky mess and the new application does a good job of removing the old application which is why I state wipe it down lightly. This stuff is almost like a wax.

Also, wipe down the blue powdercoat with car wax. Keeps the blue clean as dust likes powdercoat and it's hard to get out.

Ok I will give that a try. Just polish the inside and outside of the funnel?

Bottom of the powder measure, a couple of coats of a good car wax.

Powder funnel, if it needs cleaning, I do a light scrub with the 3M green pads to remove discoloration and any roughness that may be galled brass on the inside.

Then car wax it with a couple of coats. It adds lubricity to the moving part and protects from oxidizing. Properly polished with wax, it does not contaminate the powder and does not gum up the works. I have used NuFinish in the past with good results.

The powder bars and 550 primer slides are Teflon coated for friction resistance. Use a paper towel and solvent to clean them, but do not polish them, as this will remove the Teflon coating.

RE: Polishing parts

To be clear, you are waxing the bottom inside of the powder measure. If so any hints on removing the plastic cylinder. I removes the two phillips screws but could not remove the cylinder.
