Interiors International, Inc. You can add them to the existing railing very easily. You will want to do then so they are 4" on center(at least that is code where I live). For each spindle drill a hole in the top log and one in the floor. The one in the log needs to be deep enough to push the spindle up into and still have the spindle in when the bottom is then drop down into the hole in the floor. Put a adhesive like "Liquid nail" into the floor hole before you install the spindle. This will hold them in place. Good luck.

Ironwood Builders Do you wish to replicate the look? Rockler.com sells a tapering kit for making branch spindles. If matching existing, like the first photo, is not important and very quick fix is, look into what we call "hog panel" available at farm and ranch supply stores. 4"X4" galvanized steel heavy gauge fence panel. It comes in 20' X 5' sections for less than $50. It satisfies stair code and can be cut to fit with a mini-grinder or a bolt cutter. Attaching sections to your log handrail will be a challenge. A trip to the hardware store (or 5) will see the parts collected and the safety rail complete. [houzz=Upstairs Landing] [houzz=Staircase Fireplace]

Victor Should I add a bottom sill that I would stain? How do I line up the top and bottom holes so that they are straight?

Wood Railing Check out Mountain Laurel Handrails. http://awoodrailing.com
We can make custom inserts for those sections and ship them to you.

Ironwood Builders Victor, two ways to line things up..don't or do. A lot of the Adirondack cabins have really twisted branch handrails, why I told you about the spindle thing from Rockler. Use interesting branches and make sure they are less than 4" apart, side branches can overlap and don't worry about plumb or level...it's RUSTIC! For straight and plumb..a plumb bob or laser. Plumb bob is old school and takes two people, one holding the string on the handrail bottom center line, the other on the stair tread marking the plumb bob point. A good plumb bob costs $15.a good laser..$400.

Ironwood Builders Sorry I missed your questions earlier..I've been working instead of houzzing and I can only go back so far each evening to keep an eye out for you...send me notifications by asking for stuff from my profile.

mollykahn Add vertical logs to the existing railing and a top rail to match the lower one if you feel the railing is not high enough. As the kids grow they will be fine and the railing fits the house....even then.

Ironwood Builders First big weekend of demo. How did it go?

Victor Ok so this is one of those times that reminds me it's better to be behind a desk lol.. Now I know why my father the mason never taught me anything. Even with a demo hand held Dewalt Jackhammer it was a brutal 2 days.. Every tile fought to the end. I'm uploading some new pics now. All the hardcore demo was finished. The horrible 60's tiles are gone and the bathroom is stripped. I still need to use my grinder with an 80 grit sanding bit on the shower logs but that can wait until Friday (another day I have to take off work!). Under the horrible rugs the original hardwood floors are in great shape! We always planned on sanding and staining the main family room and small hallway to the bedroom but now because the kids room floors look so good we don't know if we should still carpet them or sand and stain as well and just add an area rug? Something to ponder. The kitchen cabinet doors and draws are all removed and now in my garage for cleaning and priming. The hinges are in great shape and I will reuse but I will clean them then spray them oil rubbed bronze to match the new hardware. All of the cabinet frames have been cleaned and lightly sanded so they also will be primed Friday... So now I relax on my second glass of wine trying to figure out what body part does not hurt.. One problem, the stupid dumpster guy totally screwed me and just never showed up so I have a heap of debris outside and no dumpster so now I have a new mission tomorrow morning..

Stairtech Railing Systems Maybe I'm too late but I would put masking tape on the floor under the railings. Layout spindle distances, use a 2ft level and a short stick to transfer the marks to the underside of the rail, drill 1/2" in the floor and 1-1/4" into the bottom of the rail the diameter of your round spindles. Cut spindles 1" longer than the distance between, put construction adhesive in holes, insert spindle in the rail, slide it down into the hole in the floor. Done.

Victor Thanks! That's a pretty darn good idea! I'm still trying to convince the wife that spindles would ruin the look so we'll see who wins. :)

Stairtech Railing Systems Wrought iron looks great with logs but you could try glass panels attached with clips mounted to the posts. See photos on my profile.
