Got a fixer-upper for my first pool table, looking for guidance

Hey folks,

New here. I just acquired my first pool table, and was wondering if anyone had any information beyond what I’ve already discovered, and some advice moving forward.

The pool table appears to be a pre-AMF buyout Play Master Inc table, made in Columbia, Missouri. Its a 7 foot table, former coin op (mechanism has been removed). It has ball return at the end of the table, something I feel like I havent seen a lot of in researching coin op tables.

The table is in rough shape but I am always prepared to take on a project. It needs veneers on its long-side aprons (I THINK thats the term for these parts), and I can easily replace those but also was willing to replace the entire apron bit. Its currently a particle board and I’ve been looking into walnut faced ply. I have a thickness planer, a table saw, ideally all the tools necessary to mill down whatever kind of hardwood I want for the aprons if I wanted to go with something even more solid.

A big problem though is that there is a crack in the slate. It goes through from topside to underneath, but not all the way down the length of the slate. That is to say, its still one big old piece, its just got a crack in it. It runs along the long axis of the slate, is about smack dab in the middle of table along the short axis, and goes from one end of the table right about to the center of the table.

I removed the cloth and its backer to get a better look at it. I havent taken my feeler gauges to it yet, but it feels like at the end of the table, there is a difference in plane of about 0.050”. If I lift on the corner at the cracked end of the table that corresponds to the lower side of the crack, the gap closes a little bit. I am unsure if there is rubble from the crack WITHIN the crack, spreading the two sides apart, or if this is due to another flaw in the table:

The slate sits upon a number of surfaces, seemingly a surface between each of the pockets, usually a platform made of a combination of solid wood (looks like SPF) and particle board. The one that the cracked end of the table is currently sitting on isnt nailed or screwed in place and appears to have come undone by previous owners. While moving the table we noticed that someone attempted to put it back in place with drywall screws. Right now its just sitting there via gravity and the weight of the slate, but whats important to note is that the surface it provides for the slate, as far as I know, is NOT level with the others.

Since I had a group of guys help me move it from one house to another, I also decided to use that muscle to get the thing more or less put back together in its new resting place while I had the help. Since then, I sawed down some 3/4" plywood and made 3 inch wide beams that run the short width of the table, and bolted 4 roller bearings on each of them to allow me to easily slide the slate around.

I’ve seen places that advertise a service to repair slate, sometimes as strong as new. These services talk about repairing a slate thats been broken in two, and so I figured if those can be fixed, surely mine can. I am also unopposed to getting a brand new slate if I can find one that fits the table. The slate is 82-⅛” long and 42” wide. I've also been scouring this forum for cracked slate repairs and have seen folks vouch for super glue/CA glue, usually thin. I reached out to Donny Wessells of West State Billiards, someone I saw in a thread on slate repair, and he agreed with using CA glue. I also saw a long comment or two from realkingcobra, where he had a "shelf crack" on a slate that was wide enough to drill 10-32 holes through and use that to assist in clamping. At the edge of the table, my slate appears to have a "shelf" crack that is about 1-1.25" wide. Might be wide enough for some bolts, but need to see if the diagonal nature of the crack is consistent all the way down.

Another approach I thought about was building some custom pipe clamps. I'm all about reusability, and despite being "custom", the pipe I buy for these clamps could be reused and repurposed as pipe clamps in my wood shop. The idea is that I would build a rectangular "ring" out of black iron pipe, drill some holes through one of the longer sections, fish some threaded nuts down in it, and then use some all thread to apply pressure. Unsure what I'd use on the bottom side to apply pressure. What clamping I've fooled around with at the edge of the table has been done with hardwood (purple heart scraps) and decent 3/4" ply. Have also thought about using some metal stock, would expect less deflection in that than in wood. Build as many of these as is necessary to flatten the crack before gluing it. This approach is significantly more expensive but does not rely on me drilling perfectly straight holes down through a crack.

I think I've got the skills to handle this, I feel like I've definitely got the determination, and most importantly I believe in myself. However, I know enough about the Dunning Kruger effect to know that almost everyone here knows far more about this than I do, and so I'm looking for whatever advice anyone can lend. I think if I can get this slate flattened back out, the rest of this rebuild is gonna be really interesting.


TLDR: Bought a pool table for 30 dollars as a project. Slate is cracked, some parts of the table need work. I think I have the skill set to fix it, just need some direction.

Thanks in advance
 
I'm not a mechanic, please correct me if I'm wrong, but it seems to me if you could get the slate flat/flush on either side of the crack you could just shoot some thin CA glue into the crack. I know you can glue a 3 piece into essentially a 1 piece. Seems like that would work, but you would have to have the surface flat before gluing.

I'm not familiar with the brand so I can't give any advice on supporting the slate. I'm guessing you would want to emulate whatever was on the unbroken side.
 
Used to sell sandpaper to Playmaster about 30+ years ago.
Can't remember the town? Wellsville?

You Mechanics might remember... They also had a factory nearby that manufactured leather pockets.

Good old days? Good days learning how not to sell.

Now I remember, it was Bland, MO.

Hey folks, thanks for swinging by and commenting. Got some info incoming.

First of all, I went and measured the crack as best I could from top and bottom, and found that its actually rather shelved. Below are the spreadsheet of my measurements and a quick graphic of the crack. Note, on the spreadsheet, the first column represents how far up the table the crack is, and the other measurements are how far in from the long edge of the table the crack is. I measured every two inches.

Here is a graphic representation of the crack made using these numbers:

Someone mentioned that I should post some pictures of the crack, all too right of a suggestion and so here are some I took when I was taking my measurements tonight:

slate crack real view.jpg


This picture shows that the crack is "Shelved" but also after doing my measurements tonight, this is almost as narrow as that "shelf" gets.

So with the shelf as wide as 4-7/8" at the end, and an average width of 2-1/8", that seems like more than ample width to allow for the bolt through method that RealKingCobra mentioned in his approach in that forum, but interested in hearing some other opinions.
 
If that was mine I would be looking for a different table. If that crack was just on the edge that's one thing but this one is over half the length of the slate going right down the middle with a secondary crack on the side and chunks of slate falling out. I will certainly compliment you if you can get that fixed up so it lasts and rolls nice though.

For the record, just wanna be clear, the yellow and blue lines in that graphic are the same single crack, its just that it has a rather diagonal angle the deeper in the table it goes.

Id be interested in getting a different slate for it but I have seen a lot of 42x82 inch slates.

Gonna at least try my best to get it playable again.

Thats you slate in the picture, correct? It looks like there is a smaller crack next to a larger crack right where the foot/head spot would be.

Ah yes sorry. That IS a second crack but it is only like, skin deep. Its one long chip sliver thay hasnt entirely broken off yet. Its about a foot or so long. I have all the thin chips that have sheered off and plan on gluing those back in once the slate is glued flat again
 
If you can get it nice and flat, tape the bottom (so the glue doesn't just run through) and fill the crack with superglue. You'll probably need some good accelerator as well.
If you have a real flat surface someplace, you can set the slate on it supported by cans for spacers.
Maybe put a strap or a long clamp across it to close up any gap.

I thought about buying a sacrificial piece of 3/4" MDF to use as a flat surface. Think thats flat enough?

You might be able to get that flat enough. I would try to get it into a place where you can shim it if necessary. Set it all up then put your level and a straight edge on the slate to make sure.
 
I repaired a crack like that, several years ago.

As Sheldon said, tape the bottom side and the cracked end, to keep the CA from leaking out. Get it as flat as you can, and glue it up. Knock the high spots of CA down with a razor scraper. Fill the voids with Bondo, and maybe even skim coat near the crack, to level it out. Use a straight edge across the slate, to check for flatness as you sand it. Hit it with some 80-120 grit on an orbital sander with dust collection. Just be careful to not create any low spots.

Keep in mind that it's a 7' barbox. Most all of them sag in the middle. I wouldn't worry too much about getting it perfect. You've already spent far more time than it's worth, measuring and plotting points.

Good luck!

Thanks for your words of encouragement. What I lack in funds to buy nice the first time, I make up for in time and so far Im not too upset with the situation

In a crack like this, the closer I get it to closed with clamping force, the less room there is for CA, and that seems ideal but is there a point where there is too little gap for even the thinnest wicking CA glue?

Also, I did not know.that bar boxes slope in the middle. This is good to know.

Did you need to drill a hole in the slate at end of crack to keep it from spreading? I know drummers that do that when their cymbals start to crack. I fear that this crack is not trauma induced and is inside symptomatic of internal stresses within the slate and bound to continue if I dont mitigate it

Thanks again

The simplest fix, is to find a used 7ft bar table, take the slate out and swap it for yours. Check with any of your local vending companies to see if they have any old Valley or Dynamo 7fts, same slates in them as yours is. When the tables get that old, most vendors take them to the dump.

I know a lot of vending companies that would be glad for you to just take their 7fts, so they don't have to pay the dump fees.

I hadnt thought about it like that. I'll have to give that a try.

I'm in the St Louis, Missouri area. Have any recommendations on vendors nearby?

And don't tell them you want the slate for a pool table, that adds value to the slate. Tell them you're looking for a 42"×82" ×3/4" slate from an old 7ft valley table for a home project, you're building a work bench so the slate can't be broke, and you'd be willing to throw the cabinet away for them so it won't cost them anything😅🤣😂

He could always do what I did with my first table that was free, it was a Fischer, I burned it!!!!
