Re: AKS altitude knobs - which washer(s) ?

Gang,
There is a problem when you try to do polar drift alignment, loosening the big lockdown 3/16-18 bolts if the AZ and Elevation.
They are either too tight to adjust the mount, or too loose to hold the axis firmly.
The solution is rather easy: put one of two 3/16 Belleville spring washer and some facing flat washers under the lockdown bolt.? Then you can gradually go from totally loose to totally tight in these locking bolts.
Here are pictures of the way it can be done.??
Contact me directly if you want specially made black or colored T- handle bolts and the spring and flat washers for this purpose.
All the best, Michael

>>I'm asking in part because one of the knobs hits a hard-to-rotate point about a half turn before bottoming out on the side of the mount, so I wanted to make sure the bolts weren't going in too deep.
I tried swapping knobs between sides to see if the problem moved. As you might expect, rather than moving or staying put it went away completely.
>>I should have checked the bolt length vs knob length before installing
The threaded section of the AKS knobs is about 1/8" shorter than the original screws, including supplied washers in both cases, so no problem there.
>>I've found the nylon washers to be of great help. I can actually do minor adjustments without loosening things. The axis' will slip under the Nylon washers. Yet they stay put when in use.
I happened to notice that but wasn't sure if taking advantage of it would be OK. Sounds like it is.
>>I recall one poster (elsewhere) who was complaining about his adjustments changing?when he tightened up the screws after making the adjustments.
Turned out, the fellow was loosening everything, then adjusting, and expecting his adjustment to be true after he tightened up all the screws he had loosened.
Ugh... I've been doing that too. At least I hadn't been complaining about it... at least not publicly
?
Thanks !!
