    I'm building in my garage and would like to use the concrete floor as the strongback and use station blocks fastened to the floor to locate the frames. Is there a way to fasten the station blocks to the floor without drilling holes that would be strong enough? I was thinking maybe epoxy? Any info or advice is appreciated. Thanks.

    Many a boat-builder can tell you epoxy sticks GREAT to concrete floors.
    Getting it off will be another matter. Do you care?
    And, more importantly is the floor flat and level?

    Thickened epoxy works great. It does not matter if the floor is flat and level, you can rig a wire for reference and vary the blocks height.
    Getting it off will be by heatgun and scraper. Wet the blocks beforehand, heat until steaming and the epoxy will let go. Then you scrape the sticky goo off.
    DogCavalry and BlueBell like this.

    I drill holes, also had chains installed when it was poured.

    Bolt holes are easy to fill if they’re no longer needed. Or use a cover so they can be used again later.

    It doesn’t really matter that much though.

    I agree, I have quite a few drop in type anchors in my garage floor for stabilizing various tools and projects I’ve done.
    My table saw and it’s infeed and outfeed rollers were the first.
    If I ever have to, I could easily fill them with a little grout to make them disappear.

    Much better to use tapcons. It is ready to use immediately and tear out is much easier.

    Noone even sees the holes.

    You do need a hammer drill
