Something strange with my scale...

I started reloading about a year ago, using one of those little cheap Lee scales. Soon after, I traded a couple pounds of powder for a like-new RCBS 5-0-5. I like it, have loaded several thousand rounds with it, and all has been well.

I noticed a couple of months ago that when I put the pan on the scale (with powder charge in it), the scale would hesitate a second or two or three before it began to move. This morning I loaded some rounds and it was more like 8 or 10 seconds before the scale moved. :eek: I've cleaned everything that looks like it might have a bearing on this issue, but I did not solve it. I've actually had to touch the end of the scale to make it move... :confused: I'm open to any ideas. Thanks!

http://www.thehighroad.org/showthread.php?t=411418&highlight=scale my 2 posts in this other thread has links that might help. Make sure there is no lube or oil on the knife edges. The surface the scale sits on should be level.

They are finicky little buggers, so like 243winxb said, clean, level, check zero often.

The most common problem is the knife-edge on the beam is rubbing on one side or the other of the jewel bearing block end-stops.

Might also check the aluminum paddle that rides between the magnets to make sure it didn't get bent & rubbing. Or one of the magnets sucked up a little steel do-dad and it got stuck in the slot.

I had a similar problem with my 15 year old Dillon powder scale. I had to nudge the scale each time to make it start. Once nudged, it was perfectly accurate.

Dillon Customer Service recommended I clean the knife edges with alcohol and make sure there was no dust or grime. When that didn't work, I sent it in for repair and, today, got a new one back. Apparently, at some point, it makes better sense to replace...

My loading bench gets a whack with a finger when my scale doesn't behave. Not that I'm blaming the bench. The balance arm is likely a wee bit off centre and the vibration of the whack sorts it out. Been known to lightly hone the 'knife' edges too.
There's a .pdf 5-0-5 manual available on RCBS' site. Powder for kit trades don't always come with the book. The twit who scanned it put the pages on sideways though.

I really appreciate the replies. I'm not sure just why, but after moving the scale to a different location, the problem seems to have disappeared. I loaded some rounds yesterday and saw no such delays with the scale's action. Hopefully it will stay that way. Thanks again!

rcmodel probably hit it on the head, the scale was`nt level side to side & the knife bar was rubbing the housing.
