I am going to pass along to you a gift – one that I believe could potentially cut your alignment times-maybe by more than half! One that could lessen loosening and tightening bolts, reduce frustration, and increase your “alignment” confidence substantially! Would you like such a gift?
Well, here it is – measure your shim thickness with a micrometer! Now I know what you’re saying:
You don’t need an expensive measuring tool. You just need to check. Why?
Here’s a good example. My laser alignment tool says to add 0.065” under the foot. There are (3) brass shims under the foot now. I add a 0.050” and a 0.015”, tighten up, and re-measure. Now my laser says I’m 0.008” too high. What went wrong? Hint: It’s not the laser!
And the end result is, I measure, loosen, re-shim, and tighten again. And again. And again! I’ve done it. You’ve done it. And the result is almost always inaccuracy.
Clean them. Measure them. Throw out the junk, and use precision shim stock. And measure them.
