Hi, I'm Dave Osborne. With over 50 years experience as a journeyman carpenter, foreman and contractor in heavy construction I enjoyed working with apprentices and sharing the tricks of the trade that others shared with me. Now I get emails from Members all over the world and we include many of my answers in our Free Monthly Newsletters. Some of my answers include drawings and instructions specific to a project, but may also answer your questions. I use correct construction terminology, so you can confidently inform your building supply dealers or contractors exactly what you need.
Membership gives you full access to our hundreds of how-to articles, woodworking plans, converters, calculators and tables. Our Stair Calculator is one of the most popular on the internet. We have projects you can build for (and with) your kids, furniture for your wife, and sheds and gazebos. If you run into a problem or need advice your Membership includes unlimited email questions to me through our Ask Dave quick response button.

Welcome to Dave's Shop Talk's Home Improvement Newsletter of questions from our members on their construction projects, a Tip of the Month and a home remodeling article, both from our website at http://daveosborne.com.
Well, Summer is over, we are into our Fall weather, now. It is time to add some more articles and plans to our website. Hopefully, I will get some feedback from our members on ideas for articles and/or plans.
Attach stair gauges to the edge of the steel square so it can slide along the stringer or rafter, maintaining the same measurements. Ref: Stairs 2: How to Cut a Stair Stringer.
Pressure treated wood is good without anything under it. I prefer to use untreated with a styrofoam gasket under it when building a house, since it acts as a gasket to fill in spaces between the plate and the concrete as well as to keep the separation from the wood and concrete. Pressure treated wood is okay.
An important prep work is preparing the stringers for drywall. To do this we attach a 5/8" or 3/4" plywood strip on the lower part of the stringers before attaching them to the wall.
An alternate to this is installing the drywall or paneling to the wall before the stringers are installed. After the drywall is installed the stringers can be fastened to the wall through the studs. What we are talking about here is making it easier for the drywall to be installed.
Obviously, it is easier to install the drywall first, but in the meantime, you can't use the stairs. The electricians and plumbers would grumble about having to climb up and down the stair opening by a ladder instead of having proper stairs. That's the reason we install the stringers first, with the strip of plywood which gives a space for the drywallers to slip the drywall down the wall, on top of the stringer. Otherwise, they would have to notch out the drywall for each tread and riser.
Another option, which keeps the drywall from having to be notched around each step, is to install a skirt with the stringer. This would be in place of the plywood strip. Then the drywall comes down to the skirt, a straight line, as it would behind the stringer, if the strip was attached first.
Preparation is the key here, also saving money is a factor with the drywall guys.
Spruce, pine, fir 2x6 joists #2 and better with strapping and bridging is good for a 16'-1" span at 16" o.c., so that works.
I would remove the existing 2x4 joists and replace with the above ones. Use a long joist hanger, suitable for a 2x10 or shorter depending on how far the joists hang below the beam. This will allow you to nail the hanger to the joist and to the beam. The missing nails below the beam should be nailed in above the joists through the hanger. The idea here is that the joist hanger is designed with a certain number of nail holes which you can't use below the beam so get a longer hanger which would allow you to put the 'missing' nails in above the joist into the beam.
The drywall on the ceiling would be considered strapping, just nail in a row of bridging between the joists at the center of the span if 14' wide or smaller. You need a row of bridging every 7' to tie all the joists together to keep them from bowing like the existing ones or laying over, which is worse. If over 14' wide put in a row of bridging every 7'.
The standard ceiling height is 8' with: 3' counter height; 1'-6" clearance above counter; 2'-6" upper cabinet and 1' clearance to ceiling. For a 7'-6" ceiling I would suggest 3' counter height; 1'-6" clearance above the counter; and adjust the upper cabinet to be a total of 2'-11 1/2" with a top rail wide enough to cover the crown molding plus a reveal of 1 3/4" or similar as the bottom and side rails widths.
The upper cabinet clearance over a stove should be 2'-6", which is cut out of the cabinet, then filled in with the range hood, bringing the clearance from bottom of hood to top of stove as 24".
I usually do the base cabinets first then support the uppers off a 17 1/2" stand with wedges. Start in the corners first then go both ways. I know some pros start with the uppers, but they usually have lots of help.
We live on the West coast of Southern British Columbia, Canada, in a very beautiful part of God's creation. I have never been to the East coast, Canada or the States, which is one of my goals. My wife is from Texas, so I've seen the country back and forth and around there.
Your email suggests you are into boating. My wife and I have a small boat, but love fishing and boating around the Gulf Islands, most of which are marine parks.
May God protect you during this storm!
Our stair calculator does not calculate the landing of a deck. Enter the total rise into the calculator with the chosen rise and run (start with the usual 7 5/8 rise and 10 1/2 run) or customize your rise. Plug in the tread thickness. Don't worry about the floor thickness and headroom, outside. Click calculate.
Your results are:
From Dave's Easy Stair Calculator at DaveOsborne.com Total Rise entered: 54 inches Number of rises: 7 rises Number of runs: 6 runs Height of each rise: 7 23/32 inches Length of each run: 10 1/2 inches Total Run: 63 inches (5'-3") Length of board needed for the stringer: 8 feet
This shows us that with this rise you have a total run of 63. You need to land the bottom step on the concrete slab, if I am understanding you correctly. So you can either build out your deck surface by 29" or so; you can put a wooden landing in the stairs of the width of the stairs (the code says that a landing in a stair must be at least as long as the width of the stairs); or you can make each stair tread wider and lower the rise, which would make the total run longer.
I get the 29" to extend the deck, as follows: 80 - 63 = 17 + 12" for the stringer to sit on the concrete = 29". You could have the stringer bottom step sitting on as little as 6", as well = 23".
What we want to do is play with the numbers a bit to lower the rise and increase the run: We can't change the total rise, but we can lower the rise enough to create extra steps. We want a set of stairs with a total rise of 54" - this can't change. We want a set of stairs with a total run of 92" = 80" to the concrete slab + another 6" to 12" for the stringer to be supported on the concrete slab.
So by playing with the numbers we come up with a 6" rise and a 11 1/2" run.
We plug into the stair calculator: total rise of 54; in the customize rise and run - 6 for rise and 11.5 for run.
From Dave's Easy Stair Calculator at DaveOsborne.com Total Rise entered: 54 inches Number of rises: 9 rises Number of runs: 8 runs Height of each rise: 6 inches Length of each run: 11 1/2 inches Total Run: 92 inches (7'-8") Length of board needed for the stringer: 10 feet Tape measurements (in inches) for the stringer (see diagram): 10 3/16 23 5/32 36 1/8 49 3/32 62 3/32 75 1/16 88 1/32 101Will this work for you?
Hi Rick, I have built storage type shop shelves for heavy parts or tools before, if this is what you are after:
The above drawing is just an example, it is easy to modify. Basically, it is 5/8" or 3/4" plywood shelves 2' wide, supported on 2x2s horizontally, screwed to the studs in the wall. The front is supported by vertical 2x4s, in your case at 3', screwed to the 2x2s. I usually start my first shelf at 2' off the floor, so boxes or larger items can be pushed under right on the floor. For this type of shop shelf, I don't put down the bottom shelf up from the floor to act as a kick space, as for a kitchen cabinet. I leave the floor itself as the first shelf.
These are very strong shelves. I've built these for transmission shops for parts, etc and for storage in a shed for day cares for kids. They are not the prettiest looking shelf, but very rugged and able to carry heavy loads such as auto parts or tools, etc. For very heavy parts, as for the transmission shop, I added vertical short 2x4s between the shelves, from the floor up.
Is this something you have in mind?
I would not use dimension lumber for a 2' high concrete wall, there are better choices. I would go with the 2' x 8' form ply. You can rent these forms which are already drilled for ties. With the dimension lumber there is too many braces needed. With the form ply and ties every 16" and tie bars to act as studs/whalers, going horizontally, is the best way to go. With this method a continuous row of 2x4s is at the top and bottom and bracing every 8' and at 4' where needed. The ties and bars hold every thing together. There is just too much weight to concrete to not support the forms, properly. I hope you are putting a footing under the wall.
I prefer to see electrical and plumbing go through block outs, through the foundation wall or footing, below the slab, rather than under the footing. The blocking, which can be a 3" plastic pipe sleeve, is large enough to allow expansion and contraction and allowing for any settling of the foundation, yet below the frost line.
I hear your concern with the cost. I formed my house forms, myself, and saved money by using 2x8 boards that were re-sawn into 1x8. Then I used these boards on the wall framing for sheathing. For some reason, we can't get those re-sawn boards anymore. I would imagine that 1x8 boards would be too expensive, even for both applications, now. The reason we go with 3/4" forms is that the ties are made to fit 3/4". I've formed quite a bit in my old 'heavy construction' days. We did bases, etc. with 2" lumber, but as I said before, you need a lot of bracing. You cannot expect the nails in the boards to hold back the weight of concrete. We usually had solid rock to brace to.
When I need to pour with a pump, I pour the footings and wall in one shot. There is no problem with leaving wood cleats between the footing and wall. I use 1x3 + or - cleats which were split from the re-sawn, I was telling you about. As long as the basement slab is above these cleats, no problem. I ran into concrete companies who would charge stand by time when you would wheel barrow the concrete to the forms, so be wary of that. I would always try to spout the concrete from the truck, if at all possible, so watch the placement of your bracing. Usually, you have so many minutes per yard to discharge the concrete. The pump is the way to go - better mix for workability, too, but expensive, alright.
I know I am "old school" when it comes to construction. I try to keep up with what is going on, though. When pouring house foundations, I like to use a vibrator, to compact the concrete. This means you have to be more vigilant for looking for possible concrete bust outs. That is something you do not want. When you stray from convention, you need to be innovative to make sure you don't miss anything.
Yes, plastic pipe sleeves are fine in the footing, just leave them in, no need to strip them like a wood block out.

The days of the back saw and miter box, I think, is a thing of the past. Today, we use compound power miter saws, also commonly called cutoff saws. Our discussion on how to cut crown molding inside and outside corners will be based on using these modern tools.
Think of the table on your cut-off saw as the floor or the ceiling. Baseboard is cut upright and crown molding is cut upside down. I usually have four sample pieces with me when I cut them, one for the inside right miter, one for the inside left, one for the outside right and one for the outside left. These are marked on them. It saves me cutting up expensive crown molding to get my head right every time. I'm referring, of course, to maximum 3 1/2" crown molding that will stand up vertically against the saw fence. Any larger crown molding would have to be cut on the flat, a very different procedure covered in my article How to Cut Crown Molding.
The first thing I do when cutting up to 3 1/2" crown molding is...read more at http://daveosborne.com/dave/articles/how-cut-crown-molding.php
