I know, there are other threads on this. I'm just not getting it. I'm attempting to flatten my bases on some Dynastar Sultan 85s with a nice edge dent (not trying to flatten that part!) and plenty of now repaired core shots. In other words, I'm experimenting with skis that I don't care much about but still use. I'm using the two Ski Vision tools (one with file and one with metal/ceramic(?) bar) and hate to admit I've spent hours on this project over the summer.
Problem is, I just can't figure out how to measure the base angle.
*I have one of those digital angle cube gadgets I've seen in other threads on this site. I bought some "powerful" round magnets to stick to the base edge. The measurements are highly inconsistent. I make sure the ski is level before I measure. At one point everything looks good. Next day, check again and everything changed. Must be the elves in my workshop. I just don't trust the accuracy or consistency of this tool.
*I have two different true bars - the typical long cube type bar and a round bar. I can't for the life of me figure out how to get accurate measurements. Just confirming that the bar is flush with the edge is near impossible as there's always some light gap at any angle and the edge isn't exactly large. Then to hold the thing perfectly still and measure 57mm away from the edge. Of course I marked it off but it's impossible to hold still and measure the height off the ski.
*True bar part 2 - trying to use a feeler gauge in the gap between the edge and the true bar. Another near impossibility. .003 for a 1* base and be slid under almost anything. These measurements are too precise or I'm just ham-fisted. Probably both.
If any of these tools is remotely correct, my bases are highly erratic along the length.
I know, just bring it in for that fictional $15 base grind (I've never seen the low prices mentioned on this board in a shop). But, I'd like to try to do this myself. Seems like it shouldn't be that hard to flatten the base and tune to 1*. "Seems like it..."
