I think the many different suggestions for building benchwork in this thread helps illustrate that there isn't necessarily 'one' correct method for building benchwork. It appears there are as many different methods to build as there are needs for different styles of benchwork. I'm glad we were all able to discuss this subject without it turning into a giant arguement....
I'd still like to see photos from those that built their benchwork with metal studs.....after all, I'm sure this isn't the last layout I'll ever be building!

Marlon,
It's funny you used 'furniture' to describe the benchwork. When I built the section of benchwork in the photo below for our fellow forum member Tom Bryant_MR, his wife mentioned it would make a fine dining table....he wasted no time climbing aboard and cutting the hole for the turntable so his wife couldn't confiscate his new benchwork!

Dave,
Thank you very much! I was worried when I first read your statement....until I read it again, and caught the pun. I figured since the legs would be visible by people visiting the train room, I might as well make them look good.....and I'm still tossing ideas around in my head for what I want to do for a fascia and light valence above the layout.
Thanks again,
Don,
You got some gorgeous legs there . . . supporting your benchwork Seriously, that extra touch does add to the layout, just as a nicely finished valence (sp?).
I recently started my retirement HO scale BNSF (modern era modeler) layout. I am using the classic "L-girder" construction method. I was going to use dimensional Pine, but both Lowes and Home Depot had nothing but junk lumber; twisted and warped.
A contractor friend suggested using dimensional Poplar, which I am doing. It is straight and knott free. A real pleasure to work with. I am using 3/4" birch plywood for the subroadbed. Like someone else commented, all screws are driven from the underside of the layout. In addition to screws, I am using Gorilla glue for some parts: the 2" square legs are actually 1x2s glued together and of course the "Ls" are made from a 1x3 and 1x2 glued and screwed together.
Respectfully,
BNSF Fan
I used pine 1X3's and 1X4's that I hand selected from Manard's. Bench work consists of modules constructed from 1X4's with cross joists 16" on centers, glued and screwed with dry wall screws. Legs are bolted on "L" girders and made from 1X3 and 1X4 with levelers on each leg. Top is 3/8 plywood screwed and glued. All covered with 2" closed cell foam board. I can walk on it anywhere at 235 #.
I predrilled the joists and the ends for wiring. Have 350' of HO code 100 in 14 signal blocks, mounted on Midwest cork roadbed. Used latex caulk to fasten cork and track. Not ballasted yet, but trains operate quietly. Half my engines have sound and I need to turn down volume on most of them. I can hear wheel noise from the ones without sound when they are close to me, but I need to listen closely when sound units are going at the same time. I like to hear the metal wheels on the joints!
Of course my hearing is not the best anymore!! (They say it's about the 2nd thing to go when you get older!!)
I use Digitrax and and feeders are #18 cables to each block. Now working on scenery. Made backdrop from 1X2's covered with 1/8" Masonite.
All this worked out so well that if I started on a new layout tomorrow, I think I would do it the same way again.
My main tip is "Glue adds enormous strength to wood construction"
-Bill
Your comments are appreciated.
The carrying of unwanted sound is really not that huge and very tolerable. However, on the next one, I will take more precautions. In addition to your thoughts on the subject, what I really should have centered on is the fact that I used track nails, which reach into the plywood and carry the sound. Given I already have two different layers (1/8 cork over 1/2 ply), I suspect the nails are more the culprit.
The layout is 12x15, three levels, located in a former bedroom (kids are longgggggg gone!) and was initiated 10 years ago. One thing I have done that I highly recommend to anyone building a layout is to keep a journal/listing of the "goods & bads, what worked and did not, what they would do again, and what they would change". My list is about 3 pages long, and thankfully the good far outweighs the not so good.

I use 3/4 birch plywood (8 or 9 ply) frequently on sale at $25 per sheet from HD and cover it with 1/2 soundboard $9 at HD. Soundboard is quiet and after I paint it with 3 coats of latex paint it looks great and had excellent nail holding properties. I use 4 OZ of tightbond per sheet to laminate the plywood and soundboard.
Benchwork itself is 100% modular 1X4 grid with 2X2 legs with 5/16 carriagebolts set in T nuts for adjustment. Masonite backdrops and facia boards.
My 2 cents, never worth a nickle more. . .

A nice looking Layout and a warm looking basement.
A note of caution for you. I cannot tell how close the gas water heater and gas furnace are to that plastic vapour barrier over your insulation, but unless the water heater is a sealed combustion chamber type, it MAY be a possible fire hazard. Check on the rating plates of both units to see what the clearance to combustibles is. The problem is, that if you get a downdraft or a blocked chimney, the flame COULD roll out around the bottom of the water heater and possibly ignite the plastic. The furnace is not so critical as the burners are at the front but check for clearances to the rear anyway.
How do I know. 41 Years experience as a Serviceman and Service Supervisor with a large Gas Company. I have seen it happen.

Hi,
Building a layout is a labor of love, and I confess that I find as much (more?) fun in the building process than when its finished - although I argue that a layout is never really finished.
I'm 63, and have built several layouts, the first being when I was 12 or so. The HO layout I built in the mid-70s had benchwork that would probably hold up a car or two, as the legs were all 2x6s and 3/4 inch ply was the main surface.
My latest layout, now with about 50% scenery complete, uses 2x2 legs 2 ft apart (42 in total), with 1x2 bracing. This lumber is your basic pine from Home Depot/Lowes, with the only criteria is that it was straight and relatively knot free. The top - using the "cookie cutter" process, is 1/2 inch plywood. I used 1/4 for the support for trackage above/below the basic level of the layout. The good news here is that it is easy to do grades and separations, but the bad news is that the 1/2 inch ply carries sound too well. A future layout will use 5/8 ply. In summary, the cheapest lumber - if you are selective - will work just great!
I covered the entire layout with 1/8 inch sheet cork (Home Depot/Lowes), which was glued down and makes a nice base for industry/yard tracks. The mainline has the usual cork roadbed which gives the main a distinct look (vs. yard/industry trackage).
Two more comments while I am rattling on........
- Cordless drills (small 8 or 12 V work great) & sheetrock screws are a Godsend for the layout builder!!! I highly recommend two drills, one with a 1/8 inch bit for pre drilling, and the other with a screw bit. I would not consider using nails, as they are too permanent and the hammering jars the layout.
- Do yourself a real favor, make the layout strong enough so you can walk on it.
Most of all, ENJOY !!!!!
I use soft pine. For my n-scale stuff that is mostly 1x2 and 1x3 (I glue 2 1x2s for 2x2 legs). It takes self-tapping drywall screws well and is inexpensive. The down side is knots in the wood that can make it hard to screw and can weaken the benchwork if not dealt with properly.
I am working on refurbishing a table saw. Once that is done I will rip the pieces out of a 2x6 or 2x8 since it takes forever to find good boards with minimal warping or bowing at my local discount lumber store.
I built the supports for my mini using L-girder with 1/2" birch plywood and for my larger layout using L-girder and 3/4" pine plywood. I don't like the 1/2", its harder to work with when joining sections. With the 3/4" I can use a 1.25" drywall screw for joints. WIth the 1/2" I have to pre-tap and use 3/4" wood screws.
I will also not EVER again put all my joists on 12" centers as I did with my mini.. just a little too small to fit my power screw-driver in. I will go to 16" min centers on the larger ones.

Chuck,
Do you grind/file off the edges? Coat them with rubber/tape? Sounds like a great idea...'cept the edges would be sharp and prone to cut (clumsy) me....

Several months ago I posted a thread, something to the effect "Pine vs. birch or fir for benchwork." The majority consensus was that though birch or fir are more sturdy than pine, there's probably no advantage in expansion/contraction issues, they're a bit heavier than pine, and, in the end the cost increase isn't justified. I plan (who knows when I'll start?) to use dimensional lumber for the L-girder frame, and plywood (prob. 1/2 inch given numerous other discussions on this forum) for the base.
Jim
I used 2x4 stud grade lumber for my (current) 4x8, using the open grid method (16" centers for the crossmembers). I used a sheet of 1/2" B-C plywood. Why did I use such heavy lumber for the framing? Because it was free. If I had to buy the lumber, I probably would have either (A) used 1x4's, or (B) bought 1x8's, and ripped them in half on my table saw, depending on whidh method came out cheaper (and which lumber looked better).

I, too, used ripped 1X4 to fashion L-girder construction with joists. I chose every piece of clear spruce that I purchased, and then stacked it in my basement for one week to equalize. Fortunately, nothing changed shape noticeably, but I did have to muscle the odd part of an L-girder together a bit to keep the two pieces lined up.
Construction of a bench, or a shelf, can often be much lighter than we estimate, particularly if we will never get up on it to do some work. This applies to the supporting legs, too. Once you have to kneel on it and do any cyclical hand movements, you'll need sturdy stock and sway braces...or it'll all go "keeerack!"
Yes, please...pre-drill. Always. That is an excellent tip.
