Autofilter Dependent Upon User Input Issue

So I was going through methods of how I can make this thing work. Provided below is my attempt to thoroughly explain my issue, and below that is my sample excel.

I'd like to autofilter a table entirely dependent upon user input in a cell. To do this, I thought that I'd need to place their input in a seperate location, with an operator "< or >", then have the autofilter update from that cell position. Also, the way my data was input creates a problem for me. For each possible bore size (Column A), there are several Rod Sizes (Column B), and each has a different "Push" and "Pull" value. If the push force isn't above the threshold, then I would like it if the rod sizes of that bore were removed also, even if they are above the "Pull" threshold.

My first question: Using a macro that activates when a button is pushed, how can put the value input into the cell next to it and insert a ">" or "<" operator?

Second question: How do I get my filter macro to understand that the bore and rod sizes are related, so that if the bore size isn't large enough, it's relative rod sizes are also filtered?
