I will be making a carbon fiber handle with polyurethane shims spaced out under the handle. Do I need to epoxy the spaces between the arbors to make a "unified" bond? Also, I will be using an arborless reel seat. What's the best way to go about epoxying it to the blank? I also want a trim ring between the handle and reel seat. I'm not really seeing a way I can epoxy it to the handle or seat neatly? Any suggestions?

If you mean a carbon or texalium tube then no don't fill it with epoxy it will weigh a ton. 3-4 on a 10" will hold fine. By arbor less reel seat do you mean exposed blank seat like acsm? You'll need an arbor/shim between the seat and tube.

Thanks. It's the MVT Toray trigger reel seat by Alps. It's set up like the Fuji ACS with the exposed blank and the built in "ribs" so you don't need arbors.

What I meant by fill the spaces was just make sure there was a layer of epoxy connecting the arbors, as with tape arbors.

An exposed blank seat is fitted to the blank diameter where it will be installed. It's attached with the same epoxy as other components. Wipe off the exposed section with alcohol. You can epoxy directly to the arbors without worrying about encapsulating them the way you do tape. Thinner layers of epoxy actually have stronger bonds than thick layers.
