Scott Parker does it again

[bloc]

I suppose Scott could be more prompt in replying to his clients, and I must admit I became a tad frustrated when I dealt with him.

But that was a very small price to pay for what I got: an M5 scale that is now the apple of my eye. I've been using it now for a month or so, and it is supremely accurate: I always use check weights to start a reloading session, and the scale is always spot on. It is also linear and reproducible. And it settles very quickly.

I consider an accurate scale to be essential for all reloading, but especially so for cartridges using small amounts of propellant (.380, 9mm and, with fast powder, the .38 Special) where being off only a small amount could have outsized consequences (being "off" 0.5 grains in a 4.5 grain charge is being "off" 1/9 of the total, while being "off" 0.5 grains in a total charge of 50 grains is being "off" 1/100 of the total charge).

So kudos to Scott Parker.

I hope so. I just bought one off ebay since I destroyed my 10-10 the other day.

What happened?

What happened?

I noticed the knife edges were not exactly vertical compared to the beam. Looks like nothing more than a rod pressed into a hole in the beam so I wanted to rotate it slightly with a pair of needle nose pliers. The beam snapped in half at the hole.

Wow you know When I looked at mine I thought that same thing anyway, I thought the knife edges were not perpendicular to the beam. I did bend mine a little but didnt break it. Sorry to hear that happened. I like the M5 better and hope you will to.

Scott told me that the pivots on the beam are something over 60 on the Rockwell scale. I would not be trying to bend them any more. dedogs

Thanks for that info. I won't try that again. if the pivots are not perpendicular to the beam though I wonder if Scott fixes that somehow?

Received my "parkerized RCBS 10-10 yesterday. Took 3 month. Checked the accuracy immediately. One grain of Varget moves the pointer. "WORK of ART !!!" Must use a "Dandy 2" like trickler to use the full potential.

Highly recommended for anyone not willing to use the expensive high tech electronics.

Keep working the phone and keep the e-mails coming. Scott eventually will respond.

That's sensitivity, and fine. But one grain of any stick powder moves the needle on even my lowly unaltered 5-0-5. The problems I experience are wandering zero and lack of repeatability, rendering the scale useless even if it is sensitive enough. My M5 is streets ahead of the 5-0-5 in repeatability. Your 10-10 should now be as well, by all accounts.

As far as the knife edges being perpendicular to the beam goes, I think that the issue is whether the angle of the agate bearings is symmetrical with the angle of the knives. Normally one would play with the weights in the pan holder to level the scale frame, but it could be done so that the frame was not level and the bearings were correct with the knife edges. Of course for the beam to be horizontal when zeroed the mark that shows that the scale is balanced would have to be adjusted by the application of some sort of overlay. How does the scale function with the knives slightly out of kilter? If it works, I do not think that it needs to be "fixed".

Well this is an old thread but always good to review and see if ive learned anything-- the bearings can move in their holders. This allows them to align with each other and the knife edges when everything is not perfect. I didnt know this post got posted.

if you check your scale with a series of different wts, say like a few bullets, things of known wt 10 gram wts this and that, and the scale checks ok, and your gun shoots good what does it mean? I did add some magnets to my 5-10 and it still weighs the bullet the same but a lot quicker,could I be doing something dangerous. sound like Fguffey now lol

someone should make a attribute gauge to check the knife edges for correct angle. It would have to be tiny used with a magnifying glass with my blind eyes

Here's a couple of problem that have shown up recently on new scales.
The first photo shows a knife edge several degrees out of vertical. (easy to fix)
The second shows the pan hanger knife edges way out of square with the beam. (not so easy to fix)

The thread angle gauge shown in the second photo works well to check the knife edge angle. The knife edge sits snugly in the 60 degree "V" and you can then see if the gauge body lines up with the beam.

The knife edge is just a press fit in the beam, not splined. It can be pressed one way or the other to centre the beam up correctly and rotated to set vertical.

To set vertical I grip the knife edge in a smooth faced vice, gripped on the round part right close up to the beam, then just rotate the beam a little.

I went about thaT all wrong a while back I bent the copper blade that goes tween the magnets, may have to start over again as usual lol

That may well be. I live in Hastings, UK, just a rifle shot from the battle field.

well they farm over there to lol, I watch a utube video called OneLonely Farmer he just got back from England he buys tractors for his farm from England. He said he could save around 25000.00 buying and shipping them back over here.

thats kind of interesting thanks
