FX-120I price increase fyi

[hoz53]

Thanks guys. The new work bench I built this last weekend has a 1.5" thick top and is 4 ft x 8 ft (2 stacked full sheets of 3/4" solid plywood). Extremely sturdy. My Gempro is sensitive to air currents as well because it has the same resolution as the fx120i. My ceiling heater will mess with it so I usually shut it down when weighing charges. Other than the heater messing up readings, I have nothing else to worry about.

Just thought maybe a slab of granite would be nice because then I could have the scale legs screwed all the way in tight for maximum stability then level the scale by shimming the corners of the granite.

I have some thick aluminum plates I could probably use too. I just like the weight of the granite.

it says in the book you should use the scale at 68 degrees 50% humidity and that should be fine for me most months but in the summer i dont have AC in my shop and when it gets 90 degrees 90 percent wonder how it will work or if i should even subject it to that. ive been planning ac in the shop for awhile so it may happen soon anyway. ive got a surface plate that was purdy cheap now that you mention it good idea.

Check on ebay, do a search for used calibration weights and you can find stuff at pretty reasonable prices. I bought a Troemner ASTM Class 1 50g weight, appears to be surplus from a lab. Comes with serial number, hard case, etc. They had it listed for $38 and I made an offer of $30 which they accepted, free shipping too. There was a pair of them and one is still available.

ASTM Class 1 is way better than the cheap calibration weights you can buy. They are rated to be 50g plus or minus 0.00012g (or to put in another measurement, plus or minus the weight of 2.5 fingerprints). The cheap ones are OIML M2 rating which would be 50g plus or minus 0.01g.

Thanks for the heads up, I made an offer on the one remaining.

Hey guys looking for granite slabs. Call people that do granite countertops. I did they gave me a few pieces that worked for my scale. Im sure they are not machinists grade but will give a good solid surface.

Recieved my scale. Manual seems a little overwelming at first glance. Now jus waiting on the rebate and some check weights.

How long did shipping take from the day you ordered? Just curious.

Monday at 3am. Made it here to western NC Thursday evening. I'd say lightening fast from Canada.

Got my 50 gram ASTM 1 calibration weight in the mail today and was able to calibrate my FX120i for the first time. FWIW, the calibration weight registered at 50.036 grams on the scale as it was set from the factory, so a bit high. Initially I had tested the FX120i using my home made check weights and noticed a difference from my prior scale by about 0.06 grains for charge weights in the 60 grain range. However, once I calibrated the FX120i it then matched perfectly with my prior check weights.

It was interesting to see that the results I had with my GemPro250 and the little cheap 20 gram calibration weight that came with it were pretty much spot on. The GemPro250 20 gram weight registers as 20.001 grams on the calibrated FX120i, pretty close. For weights in the realm of typical powder charges (25-60 grains) they match exactly. Very handy for me, since I can keep using all my prior load data exactly the same going forward with the new scale.

Very pleased with the purchase and glad I got a high quality calibration weight.

I have two 50 gram weights that came with my Chargemaster. I plan on using those to calibrate the fx120i. Not "certified" weights, but they both weigh exactly 50.000 grams on my Gempro 250 calibrated with its own separate 20g check weight.

I don't have many issues with my gempro 250 like others. Only reason I ordered the fx120i is because the Gempro is very slow to respond to 1-2 kernels. It is accurate enough to measure them as it has the same resolution as the fx120i, it's just that I hate waiting.

Anyhow, here's pics of both my RCBS Chargemaster weights on the Gempro 250. Good job by RCBS for providing very accurate calibration weights

I dummied out and did not order a weight. It is now on my list.

Looks like a good troemner is 60-70 bucks. I forgot too.

Is the rebate still in effect?

Could you use a small window air conditioner (either in a window or through the wall) and section off part of the shop. If a wall is too much a couple simple rolled up sheets of plastic will work. Tape some small weights in the bottom so it stays put against the floor and just roll them up into a few large "J" hooks in the ceiling when you don't need it. If I loaded in 90° temps, nothing would fire because sweat and gunpowder don't mix.

yeah i could do something like that and that may be wat i have to do. I need to AC the whole shop so i may just put the $ toward that. Thanks for the help/idea

So what calibration weights are reccomended? I see 100g and 50g in the manual. I wonder if the weight ceproducts sells is precise enough. Maybe I'm just over thinking this calibration weight thing.

My sister in law had some granite remnants left over from their home build. They were the chunks cut out of the counter tops to make holes for the sinks. It isn't perfectly square or rectangular, but it is big, flat, and heavy. I do my reloading in a corner. My scale sits on a chunk of that granite on one bench while the press and everything else goes on the other work bench.

Depends on whether you need to calibrate to an absolute standard, or just to a repeatable standard. If it's just a repeatability issue then one of the inexpensive calibration weights would be fine.

In isolation it doesn't really matter if you load 45.00gr every time or 45.02 grain every time, as long as it's repeatably the same. However if you're coming from a prior scale where you had been loading to 0.02gr accuracy, and you have a bunch or prior load data that you want to keep using, then it would be good to have a solid reference point.

If you're coming from a less accurate, lower end scale I would say that it would be beneficial to weigh out 5-10 charges using your prior method then weigh those on the FX120i to know what the actual weights are. That way you can make sure that prior load you worked up stays the same, but with less variation case to case.

Of course there's also the OCD factor of just knowing that your new high end scale is absolutely correct. That's mainly what drove me to find one of the nicer ones.

Messaged Ceproducts about this and Trevor said class 7 is good enough. Also spoke about reloading in my garage with wide temp swings and he said to calibrate often and be sure to not touch your weight with bare hands.

Ordered auto dump, autotrickler, and fx120i on Feb 28th. Website showed 2 in stock online. Got email confirming order and payment. Emailed sales for email with receipt so I could submit rebate. Sales response was I would get email with invoice and tracking number when it shipped. Said it should ship by latest last Friday. Week later now and no word from c-e products or email explaining expected delivery date or update even though I emailed them on Monday evening.

I'd give them a call. I ordered on Feb 8th and had no shipping by the 17th even though people in the thread ordered after me and had received theirs. I think they just forgot me. I called and it was in the mail the next day.
