Yes. Finally some light at the end of the tunnel, reverse thinking, and this project seems a bit more doable, and even not much trouble at all.
Originally I tried to get the (2.5” hardened) nails out by using a cat’s paw and a hammer to pull each nail out of the 2.5 laminated hard-rock maple strips. I figured once I get all the nails out of the top strip, it’ll just free it from the lamination, and be nails free… one strip at a time, until I have them all cleared out. I guess I was wrong. as you can see in this illustration – each nail is driven through 2.5 strips, and as such, it has a lot of surface contact between the nail and the wood creating the most friction and resistance this nail could have:

After a full day of hard labor, aching muscles, and some major bruises on the back of my right hand from missing some hammer blows. I had nothing much to show for it, as most of the nails either got broken off, or didn’t even budge to my miserable attempts.
Now that I have the base put together (dry fit) and the rough floor slab on top of it, I tried a different approach. What I did this time was pry each strip apart from the “main” slab by hammering a large all metal (body) screwdriver between the last strip and the rest of the slab to create a gap – placing a wooden wedge , and moving on – ending up separating the entire strip from the main slab just enough that I can fit the cat’s paw L shape end into it, and pry it even more apart until I can slip also the nail-pulling side of the hammer in there as well, and using both tools, pry the strip completely apart from the main slab each strip still with the nails in it – but none of them broken – this results in 2 things, both positive:
1. This is a very easy method to separate the strips apart (compared to the previous attempts at least). it proved to be somewhat fast, and methodical.
2. Now that the nails are only driven through 1 laminated strip (compared to 2.5) there is much less surface contact between nail and wood, and less friction and resistance once it come to pulling the nail out. What more -the tip of the nail is now accessible, and can be hammered out whereas before I had to DIG under the head of the nail and by doing that also messed up the maple strips.


So after only a couple of hours I was able to release all of the strips that will contribute to the dog hole strip and to the buffer between the dog holes and the skirt. I also started cleaning and flattening the area under the top where it’ll rest on the legs (so far only did the right side):

as you can see, the underside of the top is covered with tar looking layer (I guess it was used in the bowling alley to protect against moisture or leaks through the floors). I used a scraper to clean as much of it as I could before moving to the planer. as you can see, there is a price to pay as it completely marred my #5 planer – this is one of those times that I’m really glad I don’t have a $300 plane… as this would really have pissed me off:

luckily, cleaning the scraper is easy enough, and restoring the buck-bros plane would not take much time and effort. a much easier process than restoring a router bit – and the reason why I did not (yet) use my router to clean and flatten this area.
So now I have the main slab according to my plan, and the strips of maple for the dog hole strip and buffer strip – things are starting to look better and better, and this was much easier than I had experienced earlier and then I expected things to be. In fact – I’m tempted to take all the strips apart, and completely remove all nails out of the entire top – but since there really is no need for this – I’m going to hold off on this desire. I got better things to do, and really want to see this workbench finished ASAP.
Moral of this installment – to take apart a bowling alley, and remove the nail – pry the strips apart prior to taking the nail out… make a whole different experience. from “heck no way” to “gimme some more please”. now I actually believe I can utilize the other 2 slabs of bowling alley I have for other projects. :o)
and on a side note -I just received today the hardware for the vises from Lee-Valley. always good products. always good prices, always good service:

Ellen, I know what you mean – after my last experience, I was tired and very unmotivated before I started working on it this time, but after the huge difference in reduced labor, time, and psych I’m actually very energized now, and am ready to take it all up… much more than I was before working on this part.

Why didn’t you try to use a solvent to take the tar off first? That would take most of it off so you wouldn’t have to ruin perfectly good tools…

I think for the tarred bottom I would have gotten something like a car-polisher and chucked a wire bristle brush in it. That would shred up the tar and ball it all up, also packing it with dust shaved from the wood beneath. I did similar (with a drill and small wire bristle bit) to clean up a lot of the wax I spilled into my rough concrete floor. It sanded some of the concrete off and balled it up with the wax to create little hard balls I could vacuum right up.Then you could hit it with the plane if it needed it.

As a remodeling contractor, I have worked with reclaimed sections of bowling alley and I would not recommend them to anybody for fabricating a workbench.
That “dream” slab is a nightmare to work with. It is full of nails and you have to plan on disposing of a blade every few cuts.
It also sags side-to-side, so there has to be a proper structure under it that way.
Then there is the tar – crap.
It does make a very heavy and durable top in the end, but so do many other materials that are easier and take less time to handle.

Indeed Todd, it’s somewhat of a nightmare to work with. I think once you figure out how to get those nails out – it makes things much easier – still a bit of work, but not as bad, and not as destructive on tools. we’ll see how the tar will come off with the wheel brush once I get to it.
you mentioned that the material sags side-to-side. do you mean lengthwise over the long grain? or widthwise over the laminations? I have an under-top support that will help control the sagging widthwise. but nothing for the lengthwise possibility. I don’t recall seeing GaryKs’ and Karsons’ benches having support lengthwise though either, and haven’t heard from neither of them of any sagging issues. but something to consider in the long run.

I have to agree with Todd….My buddy has a garage full of bowling alley sections he salvaged, over 15 years ago..and it still sits there…nobody wants it. It would seem to me that aside from the cost, it would be much easier to just laminate a bench top from some maple, or other suitable wood. I thought about doing the same thing you are Purp, and he would give me the alley sections for free…but after I looked them over and thought it through I said thanks but no thanks!

I also agree with Todd… lol. If I had to do this again knowing what I know today, I’d go to the lumberyard and buy new material.
But at this point – I already have the material salvaged, it’s in very good condition, I already have the experience to handle it. And as Todd wrote – it’s a “Dream” top, as I always wanted to utilize salvaged material such as this for such a good purpose. Also, agree to it or not – this adds one hell of a story to this bench.

You’re in far enough to keep going for sure.
The length is fine, but all of the bowling alley sections I have dealt with are flexible side to side. As you look down the length of it, the slabs sag left to right because they are only nailed and not glued together.

My top sits on the apron on each end A 2 X 6 that is mortised into the legs and I’ve not had any cupping between the two sides. I also didn’t take off the tar. I saw no reason to do that, it protects that side from moisture, so i didn’t have to put any finish on it. The only saw blades that I destroyed were 2 nail cutting blades that I used to rip the butcher block into two long sections. I did it in the middle of one of the wood strips so it was a sacrificial strip. I peeled it off the rest of the bowling alley and had two straight sections. I made a kitchen counter top and two workbenches from the alleys that I got.
The sink cutout

The island with walnut edges.

I don’t seem to have many pictures of the maple top.

LOL. indeed far into it I am. and as of late- loving every minute of it (yet still want to see this thing finished already).
I just picked up a wire brush wheel for my grinder, and this thing works magic – I got the crimped brush (not the twisted aggressive one) and it cleans the tar off nicely and leaves a smooth surface that can be planed without ruining the plane/router blade/bit – fantastic!!! thanks Gary! this is a life saver. never used this thing before, but a good accessory to have in the box (at $10).
Karson – I was thinking about leaving the tar in place and not having to worry about finishing the bottom, but there are already some strips that are tarless (where the cross bars were nailed+screwed), so I might just clean all the tar off, and finish the bottom all at once after all. Thanks again for the inspiration!
Todd. I noticed the flexing that is caused by the nails-only construction, and made notice of that in a previous installment of this blog series. this is also the reason why I modified the ‘original’ roubo design of the base, and added cross braces supports at the top of each leg end so that the top will sit evenly on a flat surface which should take care of that sagging potential.
as jlsmith said – I’m in it for the adventure and experience. I got these 3 huge slabs for $0. In fact – I was awarded a nice drive with a fellow LJ (Ryno101) and a new woodworker buddy neighbor for going to get these slabs – so it is well worth it.
aaah… things really start to look up… now if only I can get enough shop time to dedicate to the rest of this adventure :o)

I think that I mentioned that I’m not sure if I would do it again, didn’t I? Those are some tuff-ass nails, huh?
I didn’t break any of my nails using the cats paw though.
For that black crap on the bottom I put on an old blade on my tablesaw and cut just enough to get rid of it.
If I remember correctly I glued up quarter of the table at a time. Then 2 pairs and finally the last glue-up for the 2 halves. Mine was 8 feet long and 36+” wide so I had to do it this way.
Don’t depend on the tongue and grooves to line up the top surfaces. They vary quite a bit. I imagine they were there just to help keep thing in place while they clamped them up. They would surface the top after wards.
Don’t sweat it too much since you will have to surface it when you’re done anyway.

Blkcherry- Thanks! it is indeed more of an adventure than a project – and will yield much more experiences and understanding as such once it is all over. I really just want something to work on already… seeing your bench makes me wanna be done with it and putting this thing to use.
GaryK – I thought I knew better… lol – just kidding. I was actually going to follow your advice and forget about it when Ryan contacted me and offered to team up to pick some up – how can you say no to a fellow lumberjock?
seriously though it was more of a challenge, and something you don’t get to experience everyday. another story to tell around the campfire (hopefully NOT while you’re burning the bowling alley out of frustration) :) I most definitely learned more then a handful of new approaches and techniques for the future.
as you say – I’m not going to depend on anything to keep things aligned – just close enough to keep things together – I WILL surface this thing top and bottom (bottom only where it’ll rest on the cross braces supports) for the black crappy tar – I’ve taken Gary Fixler’s idea, and got a $10 wire brush at sears for my angle grinder – this thing works magic, and leaves the maple untouched and clear of the tar in a matter of minutes! I will do the same for the top (laquer/poly finish) and then either plane it flat, or use the router +sled technique Tage Frid used to flatten tables.
I mentioned it before – I’m very tempted to take it all apart completely and remove all nails like you did… something about those nails in there bother my mind.lol – we’ll see how adventurous I feel, and how much time I have to spend on this.
Thanks again for the inspiration! even though you did suggest I shouldn’t do it ;)
P.S. something with delivery this week is in my favor – I ordered the lee valley vises, and they arrived a day earlier than FedEx predicted. and I also ordered (out of previous frustration) the Nail-Hunter which was supposed to arrive end of next week, but instead- arrived today… looks hefty – my point is – I’ll put it to use and see how it stands up to it’s advertisement and post a review on this soon -stay tuned.

Glad I found this site. I thought i was the only idiot to try and build something out of a bowling alley lane. I bought about 1800 square feet of old pine bowling alley in 18’ lengths. They only weighed about 900 pounds apiece. They had these “tee” beam brackets on the bottom and imagine my suprise when I removed a couple and th floor started to separate. I was convinced that the strips were glued and nailed. But no, just like described here they were nailed through 2 stips each. Believe me I can feel your pain as I experience the same issues from trying to separate the strips to gumming up planes. I made a wall in my master bedroom with the alleys, an island top in my kitchen and treads and stringers for my stairs. I will post pictures as soon as I figure out how. The question I would like to ask is how do you strip the finish off? I really don’t want to have to scrape my whole wall (18’ x 8’). I have tried the “best” chemical stripper from the box store but it doesn’t have much effect. This finish kills sandpaper, it is hard. If it hadn’t have dulled over time I wouldn’t mess with it but the samll area I have been able to clean is beautiful so it will be worth it to do but If

Please be careful planing as the nails can be very close to the surface depending on how old the alley was. They were often planed in place to restore them so there is no way of knowing how much of the top was removed. I kept my slabs in as big of pieces as possible for the projects I am working on. If you disassembled all the strips and removed nails you won’t have a problem but it was easier for me to screw straps on the back of my wall to keep it all together. For my stair treads I used 10” long screws driven in from both sides. I had to predrill but it came out fine in no time and they are solid.

dubya – I know the pain you’ve been going through… it can be pretty frustrating.
the way I took off the finish was using a sanding disc in an angle grinder. yes- this finish is a sandpaper-killer, and doing the one piece 30”x80” completely finished 1 sanding disc. maybe not the most efficient way, but it did the job with minimal labor, and quite fast at ~10 min for the whole thing.

I would think that a coarse Randon Orbital Sander could take it off fairly fast. But remember that you will have to get rid of any deep scratches made by the sandpaper. I’d try 80 grit before going any coarser.

I used a DA sander with 60 grit and the finished laughed at me. I have used a belt sander with 50 grit paper and it does the job but as you said I ended up with some deep scratches. I am experimenting with a gang of wire wheels on a mandrel where I will try to use them like a planer.

dubya – I used a wire wheel to take off the tar on the underside of the bowling alley – it does the job and does it well, and also will not clog (esp. with the tar). while at homedepot I noticed the sanding discs for the angle grinder, and thought I’d try them out – they are used to strip off paint and rust, and they did a great job on the finished side of the bowling alley with minimal abuse to the maple strips. also because the angle grinder is a beast at 8000-10,000rpm the work is done quickly as opposed to a random orbital sander, which is more for finishing applications.
heres the one I used:

both flap disc, and wire wheel would last about the same time, and the flap disc I think is cheaper – so might be more useful for to tackle the finish side of the bowling alley

I’ll try the flap wheel. I have some laying around from my welding days. I have had some pretty good success with an old hand plane I have. It is a big sucker with a 3” wide knife. I used a sheet of paper to set the depth and was able to plane off just the finish. As long as I didn’t go over the same area twice I wasn’t removing any wood.
