what is the biggest anyone has bored (reamed) out a FUJI ACS reel seat ??? the biggest is 17.5 mm , but has anyof you gotten them bigger by boring them out and what size can they be made to (18,18.5,19 ????)

I've never reamed one of these but I'm curious. What are you building?

I have not reamed the ACS reel seats due to the ribs.  I try to get those and any blank through reel seat fit on the blank when I order.  The ACS have pretty thin walls.

Did you mean ECS?

I have reamed the ECS blank exposed reel seats including a #17-165 to fit on a 7' fiberglass w/.845 butt.  I start with a drill bit that will slide in, then go up by 64ths sanding after each pass until it fits.

Just go slow, be careful and check often.  If it looks to thin, might want to look at another reel seat.

Good luck and let us know how it goes.

no , not the ECS , the FUJI ACS is what i want to mount , this is going on a swimbait rod . the blank is a REACTION STRIKE "SUPER MAGNUM " . the rod is rated for 4-16 oz. lures . i still have to get the specs on it ( i have some preliminary specs for it but am waiting on precise measurements ) so i am asking these things so i can get the components in line for when the rod is ready to be wrapped ..

Just my humble opinion, but I am thinking as a rod builder, that when you are planning a swimbait rod with lure weights at over 4 oz, sensitivity becomes much less important. I would be more concerned with strength. The stress on the rod blank and real seat is enormous and you can feel it when you throw these big lures. I would skip the ACS seat. You don't need an exposed blank on a rod this heavy. Get the right size trigger seat, make it fit snug and glue it up. JMHO

the ACS reel seat is for comfort , for these size blanks i have been using TCS seats , just don't find it as comfortable as the ACS . sensitivity is not needed in a reel seat on a rod that is gonna be throwing 10-15 oz. lures , that's a no-brainer  : , but anyhow , thanks for the advice ......
