The perfect GC1, 2, 3, 4, 5, &6, really?

In slate?

I think he means to relocate the hole in the rail so it lines up with the mislocated hole in the slate. If the hole in the slate is one inch south of where it should be, make a hole in the rail 1 inch south. Most of us are more comfortable working with wood than stone. Properly locating holes is preferable to matching the improper location, especially if the table gets taken apart and reassembled in the future. Figuring out which "identical" parts fit in the "identical" locations is always a test of patience.

What kind of drill bit are you using in that picture?

That would be the way to go for an old T-rail table since the threaded inserts are in the slate, but not for the post WWII tables where the bolt passes through the slate. It just wouldn’t be doable to move rail inserts over 1/2”. The rail inserts are in the correct location, it’s the slate holes that are off.

So if holes are not where they should be, they should be corrected.

Is there some other industry where this is not true?

7/8" Diamond tiped hole saw.

Do you cut that hole in the slate a little bigger or for lack of better wording - dremel a little keyhole so that your 3/8 bolt has room to be on the centerline you made? Kinda like this...

How can the side pockets be off and not the corners? If you move the rail to make the sides correct doesn't that mean the corners will no longer be correct?

Yes I think so..no matter what your business..from pimpin' to fixing tables, furniture,machines, cars what ever.

I do want to see how RKC fixes this.

For most materials the basic fix would be to enlarge the original hole in some way..maybe ovalize it and then use a washer or something to cover the extra size of the hole. In metal if is really off you may weld over or patch the misplaced hole and re-drill it in the right spot. In the case of slate the table doesn't move much once finished and the over sized hole would be hidden under the rail.

You're assuming the rail bolt is going to line up right at that spot, what if it has to adjust in or out so you can straighten the side rails?

What you do is clamp a piece of 3/4' plywood with a hole in it drilled 1 1/4" on a center line with a 7/8" hole saw. Then use that hole to guide your 7/8" Diamond tipped hole saw from walking around while its trying to drill the slate out, and as a guide to align the hole saw straight up and down. Most all bolt holes through slates today use a 7/8" bolt hole opening. So what you're actually doing is overlaying a new rail bolt hole around the 5/8" factory drilled bolt hole, only you're actually drilling it on center to match the rail bolts going into the rails.

Pretty nice. Thanks for showing us how to do that.

No I didn't assume anything, I did ask a logical question. You insinuate that is was a length / positional error. It is obvious a oversize hole allows some adjustment.
If those were granite beds it would be way more difficult!

Granite- hard as a rock! Watched them do some counters in my house.

Diamond tipped hole saw don't care about granite, marble, Brazilian slate, or any other type of rock.

If the rail bolt hole was where it was suppose to be, it wouldn't be an issue

If Brunswick can drill the rails 18" on center, one would assume they could drill the slates to match, but I'd be willing to bet anyone that owns a Centennial, Anniversary, GC1, GC2, GC3 the slate bolt holes are not on center unless someone already corrected them.

I noticed that on my Anniversary as well. It’s funny that Brunswick couldn’t get the slate vendor(s) to fix that back in 40s, and it was like this for the entire production run for those commercial tables. I can only assume they just expected their mechanics to fix that during setup.

By the fact that the same tables today have the same bolt hole issues, from the last 80 years, speaks volumes to the fact that no one pays attention, or just assumes everything is always right, or just don't care to make it right.

It is crazy. Something like that would be one of the most critical parts of a table and harder to fix in the field. - except for you haha! You'd think there would be a jig in the factories that made every slate hole exact..since they have drilled so many over the years.

 

[jtompilot]

Yes, but the most off set is in the side rails, you can't line the side pocket up with the pocket shelf, and its been that way for about 60 years, no one has done anything to correct it so the rails can be lined up correctly. The funny thing is, both sides are opposite of each other, so the rails can't be squared up before they're bolted down.

Is that why on some tables going three rail from one corner has a different aim point than from the opposite corner?
