I'm finally getting to tear up my garage walls and turn the space into a functional shop. I know that specific placement of tools is completely a personal choice and I'm going to give that a LOT of thought before I run the wiring. What I'm unsure about is what to do about the slope of my floor. From the back wall (inside) to the garage door (outside wall) there is a 4" drop in height. That slope happens in about 19.75'. It's enough that I notice it when I walk and for me to lock the wheels on anything that rolls. I've included a (poorly drawn) diagram of my possible layout for reference.

 

I'd like to have one long table that will serve the radial arm, band saw, and sliding miter. I hope to put in tracks, tape measure strips, and stop locks for the radial and sliding miter saws.

 

Here are my questions:

1. Do I ignore the slope on the left side and just create one long table that follows the slope front to back?

OR

2. Do I create a level table, along with leveling the tools, on the left side? The radial arm and band saws have their own stands. I will have to build a separate station for the sliding miter.

 

3. What's the best way to level the workbench in the back? My workbench consists of some old cabinets I procured from my college, along with a very thick/heavy countertop. This has to be precisely level in every direction. For my sanity, I can't have things rolling off the bench every time I set them down. 😆

 

4. Is there anything in my tentative layout that I shouldn't do?

I wouldn't ignore the slope. It will be a little unhandy to have the left side surfaces 4" taller at one end, but beats the rolling around things will do. So I would want the left side level the length of the room. That might be tricky with multiple stands, but can be done. As for the workbench cabinets, I think i would build a sub base (treated lumber) that sits level, and install the cabinets on that. That sub base could be as simple as just a riser along the front edge of the cabinets, or a little more complicated frame. Cutting the tapers in the wood (front to back) might be the hardest part if you do a frame.

my 2 cents

 

At all costs make SOMETHING exactly level, side to side & front to back.

the worst thing imaginable is to assemble a cabinet and find out you "forgot" to take into account the slope that you were assembling it on.

 

Have a relative that did that and boy was he annoyed with the outcome ( to say the least)

 

as to laying out a long work bench and/or work station, a laser will help out immensely. Shoot a line, mark it, build to the line.

 

Your left wall--- I would make all the work surfaces of the 3 saws the exact same plane as it will facilitate cutting the occasional extra long piece of wood.

 

Fred's advice of making sub bases is golden!! and less of a head scratching event.

 

again just my 2 cents.

Good points above.  I'd would add that if you want several tools on a single plane you will need to align the work surfaces.  A miter saw can sit below the plane by its height so the actual cutting surface is level with the plane.  I will look for some pictures this evening as example.

 

Work flow changes over time. I know several of us have posted about changing things from 1st try.  Keep that in mind.  

 

Keep everything you can mobile.  Yes it's a pain but moving stuff around with no wheels is a Royal PITA.

 

A shop evolves as does our skillset.  Plan ahead.

 

 

 

could you build a sub-floor that is level, topped with plywood?  or is height limited?  think indoor deck.

I'm with DAB. A wood floor will also be more comfortable than a concrete slab. Fix that slope with a level wood deck and never worry about dealing with the floor slope again.  The floor could also be a place to run power to the center of the shop where you can power tools that work best out in the open like a table saw. 4D

4 inches in about 20 feet is very doable.  yeah, you'll have to buy some lumber, 2x6 and 2x4, might even have to use a laser or water level to get the right heights, and there will be some cutting of lumber to create long wedges, but in a few days, you have a level floor, you can run power under the floor so you won't have to step on extension cords later, and it'll look lovely.  what's a week of work for a payoff of 20+ years of happiness?  or if you have a 6 or 8 foot level, you could do this in parts, working your way from the back (zero thickness lumber, or 1" to give the plywood something to screw to) out to the front door, 8 feet at a time, last board will be about 4 feet long.  you may also want to use some scrap to build a portable ramp to get things in and out later that are heavy.  i'd go 16" on center, and if you know about where the TS will end up, beef that area up a bit since they are quite heavy.  or just put it on top of a second layer of plywood, just the size of the leg's foot print.

I had a garage shop for years, and never really noticed the slope, but I also tended to orient my bench and miter saw table parallel to the slope rather than down it.  I don't know if the slope was less than yours, it might have been.

 

If I wanted everything perfectly level, I would probably build a raised floor as suggested.  Even if you have a limited height available you can do it with 2x4's laid flat as sleepers, shimmed level every couple feet.  Just put a strip of tarpaper down as a moisture barrier between the wood and the concrete.  In the long run, I think this would be far less work than building stuff specific to that slope.  I tend to think I wouldn't like having a table shorter on the up slope side either, but probably one gets used to that as I got used to everything being slightly tilted.  I don't remember ever noticing it really.

Will that area be dedicated to the shop...or will it have to share space with a vehicle on occasion????

I never made any allowances for floor slope (and garages are sloped by Code), and never really noticed any effects.  The typical floor is about 1 degree off level, but I don't recall ever having a problem with that.  I've never measured the cross or transverse slope (side to side instead of front to back), but I suspect it's pretty close to zero.  I have a rolling bench, and if slope was critical I guess I could just orient the bench transversely to the slope, but I suppose any tool set on a garage floor will have one direction sloped at a degree, and the other direction pretty flat.

And good luck with the layout, but don't marry it.  I think everyone changes layouts over time.

@Fred W. Hargis Jr You got it! I will need to pull vehicles in to do maintenance and repairs. I do my own work out of necessity and that's not likely to ever change. I also desperately want to prove my wife wrong by getting the car in the garage during the winter. She's convinced it'll never happen and I'm dead set on proving her wrong. 🤣  Time will tell.

 

I think I will go with your suggestion of building a small frame for the workbench. I have plenty of left over cut-offs and OSB from the shed project that would work perfectly. 

 

@Gunny I already have everything on wheels now. I used to have a 12'x12' shed as my shop/storage space. Everything got rolled out to work in the yard and then I played Tetris to put everything back. I posted a video of the space here a while back. 

 

As for the single plane for multiple machines, I'm thinking level is the way to go. The higher and lower ends will be a little weird at first, but I think it will make things easier in the long run. I also want to be able to cut long boards without opening the 16' garage door. Our part of Minnesota is frigid in the winter! When it's all said and done, I plan to have the garage fully insulated, heated, and cooled. That big door needs to open as infrequently as possible.

 

@smitty10101 Thanks for the laser suggestion! I think one of my neighbors recently mentioned they had one that I could borrow. Otherwise, it might be time for me to get one.

 

Thanks to everyone for your input, suggestions, and advice! I greatly appreciate it!

I would agree with all the above on a level plane.

Sometimes when I think about a new shop layout and mine has changed several times, I take note of some tools I use rarely and do I really need them. I noticed in your layout that you had a radial arm saw and a sliding miter saw, both pretty much the same tool. I have a garage shop and replacing the radial arm saw with a miter saw freed up a lot of space. Just food for thought.

Depending on what you make, the radial arm saw has far more capability than most of the miter saws out there. Just a thought.

@DuckSoup I love my sliding miter saw. It's over 20 years old, but I've done extensive searches for parts and I intend to keep it running no matter the cost. That said, I bought the RAS as an additional tool about a year ago. I know they have many uses, but one of my main goals is to use it for dado cuts. After I do the repair work to it and get it running right, I'll see how often I use it. Time will tell.

I'm not a fan of RAS's.  They do some things well, but I do not like the geometry of the cut much - there is a reason a sliding miter saw is usually plunged in and pushed, better geometry for a spinning blade on the move.

 

That said, I have seen one operation done on a large RAS that would be hard to do as well any other way - hogging out the butt print on a solid wood chair seat.  The blade was turned 90 degrees to the direction of travel, arm raised up on the mast a bit, and slowly worked across a seat in a slanted jig.  Worked great, like cutting coves on the table saw.

 

The other thing that big RAS was good for was extra wide cross cuts.  RAS's tend to have more reach than a slider, and that can be important if you work with wide boards.

 I guess @4DThinker said what I was trying to say, depending on your use.

I found that I was leaving the stacked dado blades mounted to the RAS and using it for just that purpose, dados. I started using my router or router table more often to make dados and the RAS a lot less. One of the several shop readjustments and space was more valuable and the RAS was the victim. Cutting wider boards on a RAS is a plus but for me it's rare, I'll break out the circular saw and a straight edge. Garage shops are a challenge for space & efficiently. 

With some help from @Gunny this is what I did with my table saw & router. Keep us informed of your progress.

 

Something to consider:  that long bench on the left side might be worth fiddling with.  First, make the bench level rather than follow the floor.  Consider converting tools with their own stands into tools suspended in "wells" (see pic):  variable platform heights, adjustable with furniture feet threaded rods, allow a change of tool in the future, while still aligning the tool bed with the bench.  Run a duct behind the bench on the floor, with risers to each tool station.  I found it handy to have a "scoop" air inlet behind each tool since most tool-direct hose connections are not very effective in dust capture.  I built mine about 15 years ago, and it's stood the test of time and a variety of tools placed in the well.

Wow! Thank you for this. 

 

I've been pondering a setup like this to allow for portable machines in addition to my chop saw. 

 

One thing I was considering was using a motorcycle lift from HD on a fixed platform to adjust the heights at the center section.  Each side section will fold down due to the limited space.  I revisit the plan in my head at 3 am each morning.

A single point of adjustment lift might not be as flexible as the four corner "posts".  Ideally, you want to "float" the tool support in three dimensions to match the adjoining bench tops.  The four adjustments allow that variance.  To further tempt:  I store the tools that might be used in the "well" (spindle sander, planer, router table, etc) on bench shelves to the sides of the well.  When I could no longer dead-lift the planer (80#), I installed a strut runner at the ceiling height, along the  front of the bench (which is 13' long), and suspended an electric lift winch which allows me to pull a tool out of the lower shelf and lift it up to the bench level and trolly it to the well.  Thoughts for 4 am?

IT BEGINS....

 

We pulled up to our house on Dec. 31, 2024 and unloaded a few things. I spent all of New Year's Day unloading the truck. This is first time that I've actually been able to see the garage floor! The most I had was a small path to the freezer. The picture is from shortly after moving in. The video is what I'm starting with now. I'll post more things as I make progress.
