i know im very impressed lol!!! I have been talking to displaced texan and it looks like im going to borrow his scope to give this a shot. Between his knowledge and everyone else on here im pretty confident i can do it. If not we will definitely be paying someone to do it. The company is located in bayville. all good i dont mind at all with all the help you guys are giving http://olympic-tool.com/

ok gothca, id imagine it is DC because the trim devices plug directly into a PCi card in a computer

while looking for the pictures i just found this literature from someone who has done the process, the blue text below outlines it. this was the process for our older machine but i would imagine it is very similar to this. Adjusting Brown & Sharpe MicroVal CMM Axis Quadrature Signal 11/25/09 - m. mcdade Each 9-pin axis plug contains a small circuit board with four pots for adjusting the quadrature signal waveforms. I did not trace out and understand the exact function of the circuitry supporting the sensors but at the time of this work, both the x and y axes functioned well while the z axis produced a 'axis error' message. Cleaning and resetting the sensors on the scales helped (several years ago, cleaning completely eliminated an error on the y axis) but, eventually, the z axis could not be used any more and required adjustment. What I found was that the 4 pots on each little board in an axis plug are associated with two test points on the counter board in the cmm control (into which the plugs are inserted). There are two test points for each axis. To adjust a given axis, connect a scope probe for the 'upper' waveform (i.e., the one associated with the upper two pots when looking at the plug board) to the upper test point and a scope probe for the 'lower' waveform to the lower test point for the axis. Set both channels to 2v/division on the scope and, in auto mode, set the upper trace to the middle line of the screen and the lower trace to the bottom line of the screen. With power on and while moving the axis in question, you should see sine waves from each channel. The top two pots are used to adjust the upper signal (on the upper test pin for the axis of interest). The upper pot of each pair sets the offset of the waveform and the lower pot of each pair sets the amplitude of the waveform. The following numbers were derived by looking at the two good axes and served to set the third so it now works perfectly. My z-axis voltages were way off before my resetting and the fact that it (mostly) worked for a long time indicates to me that these are not terribly tight tolerance numbers. top of upper waveform - 7.1 volts bot of upper waveform - 2.7 volts top of lower waveform - 3.5 volts bot of lower waveform - 1.0 volt --- Each scale unit has four pairs of emitters and sensors that see out through a pattern of bars which one of the older user manuals indicates are spaced a quarter space smaller than the bars on the scale. It is easy to trace the wiring back to the plugs and see that the pots on the plug are used to adjust the voltage level to the emitters, apparently one per pot. What isn't clear is how that translates to the two (unequal) sine waves at the test points. These seem to form a quadrature pair (the phase difference is clearly visible on the scope) but how the circuitry gets from the four physical signals to two logical ones is not clear to me.

honestly this is a bit out of my feild. Though i have a good grasp of electronics and i have used a scope before ( a long time ago) im not quite sure exactly what im looking for. http://www.deva.co.uk/product/deva023.shtml that is the device im trying to adjust and it goes on whats called a CMM that uses linear scales and reader heads to interpret a position to check to high accuracy machined parts. this is the machine http://www.publicsurplus.com/sms/docviewer/aucdoc/Brown%20Sharp%20Microval%20CMM%204.jpg?auc=496321&docid=2766514

you guys are all awesome as usual thank you, i will let you know for sure

awesome thank you! i will see what displaced Texan says and i will get back to you. i could meet you in AP to grab it.

pm'ed

Hey guys this might be a stretch but i have to adjust some equipment at work that has trim pots on it. Im not very familiar with adjusting them but I was told by the company they will work me through it if i can get my hands on one. Just cant seem to find anybody with one though. If anyone knows how to do this too my company would be happy to pay you to do it. Thanks ahead of time

Fsalter I can tell you that if you have the leuopold steel rings they are extremely precise. I am a machinist by trade and I measured them at work on an optical mwahsirng machine and I was highly impressed by the accuracy. That being said I don't believe u would find enough fluctuation to show on a standard level. I suggest the 1 inch steel so you have a "constant" you remove the variable of the scope tube from the problem. If you can't get one I may be able to help you but either way you could check each scope ring on its top plane against the rifles vertical level( without the upper half of the rings on) . And then you could rule out the rings. Also check to make sure with the rings off that both seat well freely against the tube. It's always possible it's not sitting flush . Do you have a any pics of the setup with the levels? Also I don't think shimming would be suggested. You want All the bite you can get from the dovetail so the rings aren't coming loose while firing.

hey fslater, this is my favorite mounting video, i use a modified version of this that I have come up with over the years but this will give you a great starting point (IMO). Also what they don't do in this video that i do is use a piece of 1" ground shaft (depends on scope tube size) in my rings and then i level that vertically just to make sure that the rings are sitting at the same height. Let me know if i can help more. <iframe width="480" height="360" src="http://s1078.photobucket.com/user/vmastro87/embed/slideshow/GUN%20VIDEOS/GUN%20LEVELING"></iframe> http://www.vortexoptics.com/video/mounting_a_precision_riflescope

yup thats her, and then you watch it take off straight into the air. Im going to get the go pro out there this time ! i agree lol

it seems to be working for me, i think Photobucket was having a problem before but i could be wrong.

the golf ball is hanging from a wooden stand with galvanized wire, i drilled 1/4 inch holes in the balls then hung them.

Hey guys, nothing too special. Took my new RPR to the range last weekend to sight it in and after about 15 rounds i was dead on, on a golf ball at 100 yards. Im going to start moving the ball out farther this weekend and see what i can do with it. [url=http://i1078.photobucket.com/albums/w481/vmastro87/GUN%20VIDEOS/IMG_3267_zpsigp3k0f5.mp4]

thanks for the suggestions guys. Garden state shooting center has them so im headed there now!!!
