We were finding that drawer boxes were coming out a little too wide for the openings they're supposed to fit in.  Looking into the 'F' table, we see that the E column values are for the most part set to the exact thickness of the slides, without any 'plus' value for slop variance.  These Accururide 3832 slides are 0.5" thick per side, true.  But the Accuride specs allow for a +0.03" maximum variance which is not accounted for anywhere.  So where we see 1.0 in the column E field for these slides, we'd be better off with something like 1.04 or 1.05".  1.06 would be the maximum.

Am I mistaken in remembering there used to be a variable here for slop variance on drawer slides?

Either way, without that slop variance built into the system, the drawers are tight.  Looking down the list most of the slides are like this, with exceptions.  We see that what used to appear as 'KV Light Duty' and 'KV Heavy Duty' have been replaced by 'Custom Light Duty' and 'Custom Heavy Duty'. Both of these slides have a thickness value of 1.0625, which is a pretty standard deduction for those of us used to cutting drawer parts on a table saw.  Other slides appear to have some tolerance built in as well.

Overall it seems there are some inconsistencies in the 'F' table for drawer slide thicknesses which may need to be addressed.  These are not the sorts of things new users will be used to looking for and adjusting.
