Question rod vise vs soft jaws and proper technique?

Is it worth is to get a connecting rod vise vs soft jaws on a 5" vise if I'm going to build an engine once in a blue moon?
Also do you tighten the bolts with the parting line exposed or both sides covered with the clamping surface (after hand tightening, before final torque)?


Just ordered a Mitutoyo dial bore gauge, time to start building this 496! Thanks!

Use a couple of 1-by dimension lumber (1x4's are best) and clamp between. I always leave the parting line visible.

I use a couple pieces of wooden outside corner moulding from the local lumber yard. It looks like angle iron, but made from wood. It's 1 1/8" X 1 1/8" and just lay one side on top of the vise, the other side goes between the jaws. No fumbling trying to hold the rod and line up the wood. You can also use tape to hold the pieces to the vice

Re: rod vise vs soft jaws and proper technique?

The only problem with a regular vice is getting them in it so you can get to both bolts ? Maybe with a huge vice but I just tried it with the 6" one I have here and it wasnt happening. Other than that it would be ok.

When I do them in the rod vise I have them clamped with both the cap and the rod clamped in the vise.

Sounds like a pain. The only time you really should need to torque them out of the engine is to check the rod clearance so why not see if your machine shop would let you use their rod vise and check them. I have done it a few times for customers.

One other thought . . . do you have a press ? If so just get a couple of scrap pieces of steel or aluminum and use the press to clamp the rod down.

How do you guys split the caps on rods that have dowel pins? I bought one of those splitters but it won't fit a SBC rod with the bearing in it. I seem to ding a couple bearings taking them apart.

I just clamp the cap end in the rod vise and grab the rod and move it back and forth / up and down. You can do the same thing with a regular vise and some soft jaws or actually just a rag. Does not take much to get the caps loose on that type of rod.



You can also just hold the rod and smack the cap on the side with a plastic hammer or old screwdriver handle. Comes right off.
