    Default Grinding on logs

    Has anyone ever ground out a small area on nicson snails to replace the studs with bolts? Anyone have any opinions as to how much could be ground out?

    Use a stud. Thread it into the end of the log, put the snail on and then nut it with a lock washer or a nyloc.

    No stud, hence the the question, has anyone replaced a stud with a bolt.

    Not sure what the casting thickness is (to allow for grinding) and if you dont have studs you could trim the heads off the allens and make them easily Tom

    Why not open up the mounting hole, where the bolt cahn be slid in at an angle? it shouldnt effect the mating surface.

    If your allens are long enough, doublle nut the shank, clamp the nuts in a vice and sawzall the heads off then chase the threads and viola`

    I don't think Tom was telling you to grind the head of the bolt to clearance it. He said if you don't have studs, you can grind the head off those bolts to make studs.

    Why not just run studs instead of trying to grind on everything? Seems you are just making a bunch of work for nothing.

    Snails need as much mounting area as possible. The gaskets are prone to crack where the studs are and if you remove more material....might cause a leak. Just use studs/nuts,high temp rtv and flat washers. Jim Brock on this site will sell you custom made gaskets that are a bit more durable than the green ones.

    Studs are going to be an issue because with the stud in the manifold, I can not get the snail over the stud as the oil filter mount is in the way. Believe me I am not trying to make work for myself. I am trying to make work what I have in my possession.
    I am just going to pull the manifold and put the snail on, off the block and then put the manifold back on.
