OST-053: Massaging a 20V Blacktop

[oldeskewltoy]

Well... as I expand to include more 20V head work, I'll need to expand my shim bank.



Here are about 3 heads worth of shims





Up until recently I kept all the 20V shims in a tiny ziplock bag... but with more use, it just doesn't pay to measure all the shims each time, so I bought another shim storage compartment




So with 3 heads worth of shims, the first thing I noticed is the tolerances for the shims isn't very tight. I have 18 shims that fit into the .0748 drawer, but the shims in there vary widely from .0740" - .0750". I have a feeling that as I collect shims, I'll need a bigger shim box - likely including shim drawers to the .0005".

So of the 3 heads worth of shims, I didn't get any of the first 4 sizes, or any of the last 5 - so I've placed an order to fill out my bank a bit more.....



More to come.....
