Welcome too;

Sorry if my remarks seemed 'strong'; certainly not my intention. Hope you'll stick around and join-in discussions.

..

No problem Rox - I don't claim to be an expert on anything but I'm always willing to help if I can and I know there are a lot of contributors here I will learn from.

1066,

Do you know of a UK source for tuned beam balances? - I've heard of Scott someone-or-other in the US.

If you were buying a balance for use with your product, which would you choose?

Thanks,

Rox.

Found this from Scott Parker -

Is your electronic scale giving you the blues? Does it drift with temperature or not hold accuracy tolerance? Scott Parker can modify balance beam scales to enhance sensitivity and more importantly, repeatability. Scott tells us: "You can literally count kernels with these scales--after tuning, the scales typically gain a half order of magnitude in sensitivity and a full order of magnitude in repeatability. Outside of a $250+ laboratory scale, a tuned beam scale is the most accurate and precise balance you can buy. I have tuned several 10-10s. They all have turned out very sensitive, consistent and hold linearity like a dream. The sensitivity after tuning is such that one kernel of powder registers a poise beam deflection. For repeatability, I remove the pan and replace it for the zero 10 times. The zero line and the poise beam balance line must coincide for each of those 10 tries. I then set the poises to read 250.0 grains. I remove and replace the pan 10 times with the calibration weight. For repeatability, the poise beam balance line must return to that same balance point ten times. I then adjust the poises back to zero and recheck the zero. A report is generated detailing the initial inspection of the balance, the corrective actions performed and any remaining concerns. I sell Ohaus type 10-10 and model 5-10 scales for $70.00 + shipping. I can also modify your existing 5-10 or 10-10 scales for $20.00 + shipping. Email me at VLD223@yahoo.com or call (661) 364-1199."

Scott Parker's scales have an excellent reputation, the problem is getting them to him and back again.
Here are a couple of clips about tuning up scales.

The Targetmaster will work with most of the standard beam scales – It won’t work with the Lee safety scales, the RCBS R130 (round beam and plastic base) and the large, upright RCBS304.

The TM works well with the RCBS 10/10 scale but as the sensor must be placed to the front of the scale it’s not so convenient to use as the more usual scales.

Here is an article written by Laurie Holland concerning the Targetmaster with the 10/10 scale.

The RCBS 502, 505, 5-10 and the 10/10 all use exactly the same Knife-edge/floating Agate bearing set-up so they are all as accurate as the other – the 5-10 and the 10/10 are more heavily damped (maybe too heavily) and both have a vernier poise adjustment and an approach to weight mechanism and the 10/10 has an extra weight that can be used as a check weight and allow weighing up to 1100 grains. All the RCBS scales are made by Ohaus in the USA and you may find the same scales painted grey and sold as Ohaus scales.

The Redding No 2 scale is an excellent scale and also the larger Hornady/Pacific scale

I find the Lyman scales are, in general, not of the same quality and accuracy as the RCBS scales. They have very small knife-edges and fixed agate bearings. I would not recommend the newer Lyman scale with the plastic base.

The old Lyman M5 was an excellent scale, it was the forerunner and better than the 10/10 but is no longer made.

Personally I use a 502 as my regular reloading scale. (I have about 20 different beam scales)
