Author Topic: Scope Ring lapping tool (Read 2480 times)

I'm getting ready to buy a scope ring lapping tool. I have found two with big differences in their price. I found one at Sinclair International for $17.00 and the other at Brownells for $40.00. The differences are: Brownell's bar looks to be a little longer, has two handles and the bar looks like it has fluted rings around it versus the Sinclair bar that is a little shorter, only one handle and their bar is a plain solid steel bar. Other than from a luxury or beauty standpoint is the $40 dollar Brownell more expensive because it is better than the Sinclair?

I mean, as I see it, its not rocket science as lapping is just steel against steel. Is there any reason to buy the more expensive Brownell bar?

Thanks,
Toby

I use a piece of good quality cold rolled steel bar stock. Don't need a fancy handle to lapp a set of rings. KN

Dunno where I got mine as I've had it a long time. It does have a handle on both ends but is not fluted. Is pretty long. If you have only one handle I'd think you'd want a single handle. Me I like the idea of two handles.

Got mine from Russ Haydon's shooter's supply on the Internet for about $14. He's located in Gig Harbor Washington. Has two handles. Non fluted. includes lapping compound and instructions. Well made and works very good.

Geno,

I ran across his website last night and saw that it was pretty good price, no pictures though. I'll have to find his website again tonight and give him a call on Monday. Thanks for the tip.

Anybody have any tips on how to securely hold a handgun to make lapping the rings an easier task?

Put it in a vise.

If you've got a metal fabrication supply in town, go and buy a piece of 1" round solid bar stock. Also, most major auto parts stores sell valve lapping compound, which will work as the abrasive for shaping up the rings.

Have that local machine shop use TGP 4140 to make a lapping tool. It is ground and of precise size. Have them turn a shank to fit in a cordless drill about 2" long on one end of a 15" piece of this steel. Mine has a grove about .025 geep similiar to a thread that runs the full length. This carries the lapping compound through the rings. You will find Valve lapping compound to be too coarse. This tool makes quick work of a lapping job...Dallas

My tool cost $5 from the local blacksmith, cold rolled steel with a handle welded in the middle. I use valve grinding compound, works great, another $4 for more than you'll ever use. Use a figure eight pattern on the rings, it cleaned mine up great, especially my three-ring set on my Encore .454, and it tracks great and holds zero now, unlike before, even though it's a Leupold it didn't like the misaligned rings.
