The instructions for the wheel kit to be fitted to an Incra (oblong) router table, state that the movable wheel should be fitted at the opposite end to the feed. I can see why this is, because having the wheel, bracket and pedal at the feed end could result in a trip hazard - especially dangerous when hands might be near the cutter.
I wonder if anyone uses their table with the movable wheel at the feed end and whether it does cause issues?
I have limited space in the shop and sometimes need to rotate the table from its normal parked position, to allow for long workpieces. Due to the limited parking space, it would be much easier to rotate the table from the left-hand end.
If it's thought to be really unsafe, I could consider fitting modified brackets at the feed end with rotatable casters fitted with brakes, but I've always considered that either fixed wheels or lowering onto fixed feet was more stable.
