505 Scale Retaining Tab Thingy Broke... Needed?

[Joshua M. Smith]

Hi Guys,

The retaining tab on my Lyman/Ohous 505, the circled part on attached to the number scale, snapped off:



Is there anything special this does besides keep the beam from falling out when jarred? The scale still works fine and I really like it. I can go to an old cast iron Redding liquid damped which still works nicely, but the 505 Lyman/OHaus is my favorite.

Thank you,

Josh

I can't see any reason that the loop needs to be closed. So long as your index marks are intact, I see no problem whatsoever.

The loop is a stop limiter for the beam in the event of a overload.

Just curious..how did this part snap off? Do you have a set of calibration weights to check your scale?

Very sparingly apply some JB Weld and put it back together! After it dries it will be stronger than when new.

Agree with all the above posts - you probably don't need it, & if you have the broken piece, it can be reattached

I'm just wondering how you managed to break it in the first place? And in this regard, I would be concerned that the scale hasn't been damaged in some manner, check weights indeed.

Hi Folks,

I bought this scale used, checked the calibration, and it was good.

The previous owner had taken the beam off by bending the retainer -- several times. It was holding on by a prayer and when I went to see if I couldn't bend it back as it should have been, it came off.

Just a matter of the previous owner bending the retainer instead of turning the beam 90° to remove it from the scale.

But yes, it calibrates fine and isn't damaged in any other way. I might try JB Weld; I am not sure if I tossed the piece or not.

Thanks folks.

If you need a bump stop you could jamb something in the slot behind the tab.

Use some common library paste/glue stick to Glue a (non-metallic) toothpick across the top of the magnetic damper slot.
That will keep it from over traveling "up," while the bottom of the existing slot already keeps it from overtraveling down.



(paste is easily removable if/when desired)

I would email Ohaus with the question. They rebuild their scales all the time. They might even do it for free, or at a small cost to go over your scale and rework it completely. I also agree that it is safe to use as it is.

This piece can be totally ignored. If broken don't bother fixing.

"an overload stop"??????? The table top does a wonderful job of that, even better if the piece is gone as there's now no way to force an overload on the bearings.

Move forward as if there was no problem at all. There really isn't.

A call to RCBS would probably bring you a new one, along with a couple of rivets.
But probably no effect using it like it is.

Ive been using a Lyman Ohaus scale for years that is similarly broken - no problems, it just limits how far the scale can bottom out.
