If you have 5" seperation of your rings then you would need .04363" for a 30 MOA base. Ed |

thanks guys, I'm going to try out with half degree for now and see how things work out.
Competitor, you mean by how much inches the front of the base should raise off from the action? BTW heres a photo of what just arrived!  Going to mount it on my Rem 700sps 308 for now until I get all my 50 BMG reloading equimpent in to load my own rounds to save money on ammo!

Thanks competitor for the info that I was grasping for. Should have known to call on you for that level of info.
Huskey, the rear will always be higher for a projectile firing weapon. Notice that the info that competitor gave was based on rings 5" apart. Yet the numbers would be higher if the rings are further apart as I mentioned before. |

You can do whatever math you need to with "Basic" trig.
here is an example. If you need to (I often do), go on youtube and have one of the nice people there teach you highschool math again. 
As far as plugging this into a CNC machine I don't know that the front/rear heights mean anything? if you can plug in degrees to a fine enough measure (.5 degrees in this case), it should do it by itself, no? |

Got all the front and back confused when I was typing in the message, then when i left i realized its the rear thanks for clearing that up though!
Led, yes that is the correct trig, but you do it differently than I do. the way you do it is to find the length first. I just find the height of the .5 degree from the known length. Current stock base is 7.6875" long by .9375" high from base to top. My calculations for how much the rear needs to go up came out with .06708" (7.6875*.5[tan]= .06708) or in other way 7.6875 *0.0087268677907587893345361980612= 0.06708779614145819300924702259549 (copied from calculator) I use SurfCam and it will tell me how much I need to add to the rear once i tilt the part by half degrees. Haven't got time to draw it up might do it today. |

I think this has got to be one of the most technical threads I have seen in some time.
