Home Forums Hunting & Shooting Gunsmithing Ring lap rod 30mm

Anyone know where to buy just a 30mm ring lapping rod. Not looking for a kit with alignment rods and other things I won’t use.

Manson makes a scope ring alignment reamer. It's a bit pricey. If you have access to a lathe, you could make one.

I made mine!

You want to rent yours?

30mm DOM tube is available but not too cheap.

That one is only 4" long but you could try contacting them and see if they'll sell you a specific length. Online Metals is another source or try a local hydraulic repair shop for a cutoff. For lapping, I'm not sure if a hard surface rod is the best, but it should work. You typically want the grit to embed in the lapping rod, not the work.
As mentioned, making one from a larger standard tube is another way, if you can find a shop locally.

Edit....ran across this one in the classified section too https://www.24hourcampfire.com/ubbt...04529/gonew/1/wheeler-lapping-kit#UNREAD

Though a kit, for $30 it's pretty inexpensive. I have been using the 1" kit and am pleased with it.

Had a buddy with a lathe make my lapping bars. Pretty basic to make. Th3n drill and tap a hole in the middle 90 degrees to the bar for a threaded handle. The handle can be as simple as a bolt and a short piece of pipe. I only lap the bottom rings to get 80% or more contact so I don't need fancy expensive store bough stuff.

Thanks guys.
I’ve resolved the search.

30 MM is just a bit over 1 5/16 inches. Get a piece of 1 1/4" hardwood dowel rod and wrap a couple of layers of ultra-fine sandpaper around it.

I got mine from Sinclair.
