Welcome

Welcome to those who have joined us since our last Newsletter in December, 2003. Thanks for submitting the survey and comments. With the new year upon us, Dan and I hope you all have a safe and enjoyable renovation year ahead.

News

With a new year comes new additions to our site. Here at DaveOsborne.com we are starting a new phase in our web site. We are installing Visa and Mastercard right on our site to make it easier for people to deal with us directly. Dan tells me he'll be finished this in a few more days.

What's New

A new feature we added to the site is a place for members to put photos of their projects, especially ones that I helped you out with. Seeing pictures from our members, those of you who felt you couldn’t attempt a particular project, hopefully will have enough confidence to try it yourself. After all that is our motto - Building Confidence. There is more room to share your project pictures. Thanks to Hans and Chuck for their contributions. Just send your photos in an email to me.

Thanks to our member, Steve, for suggesting a calculator to figure out the volume of concrete needed in a certain size of form or footing. Just plug in the width, length and height, in feet and inches or metric and there you have your volume of concrete needed to fill the form in cubic yards or meters. Dan went one further, with discussion from Steve, to add the number of pre-mixed bags for small pours as well. Check out Table 9. (http://daveosborne.com/dave/articles/formcalc.php) Dan just loves doing this type of thing. He is a mathematical genius and hasn’t been stumped yet. Send him your thoughts or ideas for new calculators.

And what has Dan’s older brother been up to? I added the second part of my article on installing crown molding - Renos 12: Cutting Wide Crown and Cove Moldings (http://daveosborne.com/dave/articles/widecrownmolding.php). Don’t tell Dan, but in between answering questions from our members, I sneaked away for a week with Frances (my wife) and cruised the Western Caribbean. It was a last minute thing, we joined my cousin Kathy and her husband, John. Thanks, Fort Lauderdale for your hospitality and the Everglades air boat ride, we actually saw two wild alligators. Twas the first time snorkeling for Frances and myself, we loved it - better than pounding nails in the wintertime.

Ask Away!

Here are some questions I've been answering lately:

Greetings Dave Osborne,

My question was… when installing barge rafters to support an overhang
on a roof, using 2 x 6’s, is there a standard (or recommended) spacing
on how far apart to set the barge rafters. My overhang is 32", it’s a
10 in 12 roof with a span of 17’ plus the overhand. My rafters are on
16" centers and I’m going in three rafters due to the long overhang.
Any info would be appreciated.
Regards & God Bless,
Bret

Hi Bret,

When framing for a gable end overhang, usually an overhang up to 16"
can be done with out building "ladders" or "look outs", as we call them,
for the overhang. In your situation, with a 32" overhang you should use
the ladder technigue as you have chosen. The rafters going out 90 degrees
with the gable end usually sit on the gable end truss which is cut down
by 3 1/2". The look outs , then are 2x4 on edge and usually go inboard
over the gable end truss into the next truss laid out on 24" centers.
In your case with 2x6 rafters, I would do the same, except as you say
remove one rafter from the the gable end and attach the look outs into
the second rafter over from the wall line, at least 24" from the wall
line. On the wall line build your gable end rafter lower by 5 1/2" (or
3 1/2" would do, too, depending on the choice of barge boards matching
the fascia). These look outs should be laid out on 24" centers starting
from the eave where your sheet of plywood starts. May as well have the
4' joint of the plywood butt up on one of the lookouts. Also, the ridge
board should continue and catch the overhang rafter on the top and the
rafter trim catch the bottom. When installing the plywood, try to get
most of the sheet on the roof to help support the overhang. Stagger the
sheets here by only 16" with the longest sheet in the center of the span.
That is, make sure the overhang sheet nails into a rafter at least one
inboard from the lookout connection. This way, your sheathing helps support
the overhang, too.

Here is a drawing to help explain, this can apply to rafters, as well:



Hope this helps,

Dave

Dear Dave,

Thanks a ton for the information and drawing, that’s exactly what I
needed! I really appreciate your site and its’ thoroughness, not to
mention being able to ask you this type of question and get your expertise.
Thanks again!

Regards & God Bless,

Bret

Dear Dave,
Your Renos 11 on crown molding was great. Could you please expand upon it
and discuss working with wider crown that has to be cut flat on the table
of a compound slide saw. Thanks for any help. Project will be interior paint
grade crown in Santa Barbara California.


Hello there Santa Barbara,

I got a bad sunburn one summer down your way.

Thanks for the kick in the butt. I needed to finish that article.

Here it is. I'm sending it to you right away rather than wait till Dan gets
it up on the site. Also keep an eye on the table that is mentioned at the
end. I'm still working on that. It will be useful for those who install large
crown on not too perfect a corner, as well as other angles, too.

Regards,

Dave

The article is now on the site, refer to Renos 12.

Rod replies:

I am absolutely blown away to receive such a complete great explanation and
so quickly. Although older, I am a relatively new general contractor. Been
doing property management for a long time. Therefore I know a lot of people
in the trades and I can assure you I will be telling all of them about your
site. This is just fantastic! Thanks again. Please feel free to comeback and
visit us anytime here in paradise...after all we now have sun blocker so you
won't get burnt again..and it really is very pretty here. Take care. Rod in
Santa Barbara.


And me again, trying to get the last word in:

Thanks, Rod, for the nice reply. You are more than welcome.

I'll be down your way again and will have to try some of that sun blocker
stuff. Actually we have that up here too, we call it clouds!!

Dave



*********************************************************

I need to install a couple plumbing vents for sinks I am installing and would
like to run the vents horizontally through a side wall rather than through the
roof. Is this OK to do? If so: 1) Do I need to install them so they tilt down
a little to keep water from following the exterior of the pipe into the wall
and 2) How do I terminate the pipe, with a vertical T or just cut off the pipe?


The purpose of the vent is to ensure that the p-trap is not siphoned out, it
breaks the siphon with a vent. The vent will contain sewer or septic gases
which smell and are flammable, that is if the sink drains to the sewer or
septic tank. This is the reason they are always installed through the roof for
the wind or air to disburse the gases. Try to get it up the inside of the wall
and out the roof or into the attic to a reachable place then up through the
roof. In the "old days" it was allowed to run the vents on the outside of the
house, but still they had to be run up the roof, usually in the overhang.

It would be kind of embarrassing to have a friend walk by the vent at nose
level, which would be bad enough, smoking a cigarette and poof, loose all
his hair. He wouldn't be too impressed, either.

Better to do things, right.

Dave

A follow up:

That makes sense, thanks. One more question, does the vent have to be
installed directly above the P trap, e.g. with a "T", or can it simply be
close to the P trap, say within a couple inches? In one of my applications
the drain runs in horizontally and ends at the trap. The way I have it
installed is the drain ends in a street L connected to a T on the downstream
side. The vent runs vertically off the T, so it is actually downstream from
the trap. Should I change it so the vent runs off the end of the T and the
trap connects in the center of the T?

Also, how many sinks can be connected to the same single vent?

Thanks

What you described is okay. The number of sinks for one vent depends on the
size of the p-trap and vent. For a 1 1/4" p-trap and vent, only 1 sink is
allowed. With a 1 1/2" p-trap and vent you can have 8 fixture units connected
where a lav (bathroom sink) is 1 1/2 fixture units, so that's 5 lavs off one 1 1/2"
vent. The trap can be 5' from the vent. You are allowed to use half the
diameter vent as is the drain. So for a 3" drain for a toilet, you can still
use a 1 1/2" vent. A toilet is considered 4 fixture units. This is just about dry
vents, when you are talking about wet vents, relief and circuit vents that's
different.

Hope this helps,

Dave

Dave, I have recently contracted to perform stair building for a GC here in
Florida, for a Townhouse Complex of 3 units. Each unit has a U shaped set of
stairs consisting on 4 treads landing another 5 treads, landing and 4 treads
and floor landing. the question is typically the stairs are made with a full
2x12 stringer and a cleat nailed to the stringer for attachment of the treads
and risers. This way the stringers are used as a side board for the base of
the stairway. There is a product on the internet called Easy Riser made by
Universal Forest Products
Do you think this is a good product to use for this application.


The easy rider system looks okay, but it is similar to the open stringer, where
you notch out the treads and risers. You say your GC (General Contractor) wants
a closed 2x12 stringer with cleats. These are two different methods. So to
answer your question. No, the easy rider is not a good product for this
application - closed stringer.

Dave

[Note: I really don’t like a closed stringer for stairs where the treads are
dependent on a cleat nailed or screwed into the stringer to support them. I
prefer the open stringer where the treads are attached to the top of the cut
out stringer. If a closed stringer is preferred, go with the open stringer first
then nail a closed stringer on the outside. This gives you the best of both
methods. Another disadvantage of a closed stringer on an outside set of stairs
is that it traps water in the corners, either building up ice in the winter or
encouraging rot.]

From a member

Dave,
Love your plans, will help greatly! In process of starting to build a garage
workshop. Do you know where I can get plans for utility wall cabinets, have
been unable to locate any old kitchen wall cabinets, thought I would tackle
the building process



We have some plans for a corner cabinet
(http://daveosborne.com/dave/projects/cabinet.php), which may be helpful.
They have instructions on dados and gables which you may be able to apply to
your project. If not, let me know where you need the help.

Hi Dave, I was wondering if you have any good solutions for getting rid of the
smell of wood stove smoke? My house was filled with a great deal of smoke and I
can't get rid of the smell. I have placed white vinegar around and cotton balls
soaked in vanilla extract. Any ideas would be appreciated.
Thanks,
Kip

Hi Kip,

The University of California at Berkeley has a good web site by the parents
group which answers questions like yours. Here is a link to it:

(http://parents.berkeley.edu/advice/household/smokesmell.html)

Hope this helps,

Dave

Follow up:

I did check out the site that you suggested. Thanks. Just for your
information, vinegar works wonders on odors. Setting out small pans
reduces odors very well. Another good idea is cotton balls soaked in
vanilla extract. Hope you can use this info some time.Kip

Thanks, Kip,

I'll use that in the next newsletter. Vinegar is an amazing product. I
should have asked my wife, she has "The Complete Vinegar Book".

Glad you got the problem solved.

Dave

I’ve had a few questions lately on methods of fastening stringers to the
floor joists at the top, especially if the stringer comes below the joist
leaving nothing to fasten to.

Here is a sketch to help:



Notice at the top we cut back the stringers the thickness of plywood to be
used to hang the stairs onto the back of the stringers and fastened into
the floor joist. Fasten the plywood onto the stringers first, then lift them
in place as a unit. For the bottom, a 2x4 is securely fastened to the floor
with drill and anchors or shooting concrete nails in with a gun. The stringers
are then notched over the 2x4. What is important is the posts supporting the
stringers, so you don't just rely on nails.



Dave,

I've printed out your instructions - they are fantastic! I'll be ripping out
the carpet and such, and will (hopefully) start them tomorrow. I'll let you
know how they turn out.

Thanks again for all your help and support,
Gary
