- Join us as we build a log circle stairway the smart and easy way. This once very complicated task is made simple by using tools you already have and some tools you have never heard of, and they aren't as expensive as you might think.
Camera Girl & I met in the early 70's when we were staff members at a children's Bible camp, and soon after graduating High School I went to work residential home builder/general contractor who put me through my apprenticeship to become a Journeyman Carpenter.
By the time 1978 rolled around we had married, produced 1 tiny infant, completed my 4 year carpenter apprenticeship program, become a Journeyman Carpenter, purchased 40 acres of farm/forest land and moved "up north" to pursue a dream of building Scandinavian Full Scribe Log Homes.
Over the course of the next 14 years we built 10 full scribe log homes, did the the carpenter work and giant log trusses for a convention center and produced 2 more offspring. Also during that time we developed the initial tenon cutting design that would eventually birth Tenonizer Technology LLC. and built our first high-bred Log Accented, Conventional Built Home. Incorporating what we considered the best of both worlds, we put log posts & beams, log floor joists, a log circle stairway and log handrail on the inside of the house, and low maintenance, highly weather resistant ruggedly handsome product on the outside of the home.
Then came our second year of high-transition; 1992. We sold the 2 homes we owned, purchased a remote chunk of woods/water property a bit further north and began the business called Tenonizer Technology LLC. Over the next few years Tenonizer developed an assortment of log furniture/log handrail building machinery which was sold and shipped across the US, Canada, and Newfoundland. There was radius shoulder tenon cutters, from the simple TC 22, the giant and totally automated TC 338, and the compact but fully fast and automated TC 300. There was also sanding machines, log corner notcher's, tilting column drill press, and laser guided drills. We pressed to put the best, log furniture, log handrail, log accent, processing/building ability within reach of the average homeowner, builder, contractor and shop owner. We built and sold a lot of stuff.
Next came the beginning of instructional video portion of our endeavor, Log Furniture 101 was the first video we produced in the late 90's, with 2 more Log Handrail and Stairway Log Handrail videos close on its heals.
Shortly after 9/11 struck we teamed up with a producer who assisted us with the Outdoors Channel TV series A Piece of the Woods, a 13 episode series which aired on the Outdoors Channel in 2004, we then fitted portions of that series which was broadcast on PBS. In 2013 and 2014 the bulk of that series was placed on our RUclips channel, Tenonizer, log furniture, timber frame, and Life.
It is our pleasure to have you join us on this journey

My favorite show
Both informative and hilarious..I love buddy's little groans.
instantly subscribed lol thank you for this video making a tree fort for my kids circular log staircase would be perfect!
You are most welcome Jedd, lots of ways to work the basic concept, laser guided drill is key, and you can easy make one of those😎😊
Great Video! Can anyone please shed light on how to purchase or make the air pump sander featured in the video? Thanks to all.
This video is better than This Old House.
Thank you for the kindness Mr Gnome👀👍
love the video! Can you post something on how you spin those monster logs? Very curious about the 'dollar fifty lathe.'
Thanks so much!
We finally got around to it Trevor, check out Tenonizer's video, posted 1/25/2020, Turn your table saw into ..., sorry it took so long.
Amazing video! Beautifully explained and wonderfully done. I can't find the next video you mentioned - the spiral rail that came next. Which video came next? Can you link it here or give me the name? Thank you for sharing your wonderful work!!
Hi Kara, How nice😎, amazing! Thanks so much. This should be the one you want, from the Log Circle Stairway playlist on our homepage😎😊 ruclips.net/video/EkpS_RxEShU/видео.html
I appreciate all of your generous answers so far and I have just one more. I purchased the 4 5/8" Milwaukee bit which comes with a couple of smaller lead screws than the one you used in the video which looks to be custom made from some threaded rod or something. Anyway the largest of the two lead screws with my bit is 5/16" I believe..Now I'm wondering if an 18" @ 5/16" auger bit would be sufficient to get the job done or would you recommend having a larger lead screw made up to follow a larger guide hole? 1/2" maybe? This is just a one off project for me (personal home) but I will be drilling 14 holes into 12" of ash so I'm a little bit concerned about a 5/16" bit of that length wandering or breaking over the course of the hole.
Hi Justin, the lead screw we use is made of 9/16" dia. fine thread with a hardness about the same as a grade 5 bolt. The shank has been cut down to fit the 3/8" dia. of the Milwaukee bit with 3" protruding out past the bit, with the first 1 1/4" of that is cut down to 1/2" dia. with a bullet point. That tracks perfect with a 1/2" hole drilled with a laser guided drill. See our log circle stairway video.
Love the video. Can you tell me what the nylon brush is call and where I can pickup one
The individual 1" x 6" nylon bristle wheels can be purchased through Grizzly Imports, part # G3300, an Osborn brush made of the same material works great also, just search "Osborn 6" or 4" ATB"
Where is the info for the layout of the treds...there is no website.
Thanks for info. I can't send you to cut it for me cause i leave too far away on an island near greece. I will try make it happen alone cause none woodworker here can even try to do it. They even laugh at me,but your video is really helpfull and i hope i will eventually done it! Thanks again
Savvas, look at the video, (1-2-2020 The Best Radius Shoulder Tenon Cutter on Earth) it shows how the TC 300 works and the air/oil movement system of it, although it's movement is opposite of a radial arm saw, you can reverse and copy its action with an old radial arm saw and do it yourself; (that concept, radial arm saw moving over a rotating work-piece, is how our TC 338 works) and if you have questions along the way, just ask, I will try to answer them... oh by the way, lots of people have laughed at me along the way too... don't care
Haha! Thanks a lot!
nice.. i wonder if a live tree would live through all them holes.
5:00 - 3/1 safety factor can only be used for cranes and elevators. everything else is 5/1 . 10/1 involving human danger, such at a man lift or ppl being under a load. check ur laws in the area.
We have built circle stairways into live trees, where the trees are still doing fine, (one was 20 years ago) but we use 1 1/2" dia. stainless steel for the pin going into the tree to keep the tree healthy.
Circular stairs ruin old people's knees,every step is a twist on the knee
The tightness of the turn is what can cause a problem, making a much wider walking path as we did on the circle stairway shown is much better on the human body. Sad to say, the one shown here would not pass most city building codes because the stairway walk path is wider without a second inner handrail added.
Dear,
Thank you soo much for all these videos, you have on your channel.
I'm writing to you from Serbia and have plan to build spiral stairs in my winter house.
I understand every step (I think :-)) and only misunderstanding is about proper type of wood. Firstly, I want to prepare and buy material for stairs and would to know which material is best? Is that oak wood, acacia wood, ash wood, walnut wood or cherry wood? :-)
Thank you in advance and please forgive the spelling mistakes.
Greetings to you in Serbia from the the middle of Minnesota! The center column is a conifer, white pine, fairly soft and easy to work with, the treads are eastern red cedar, a fairly hard tough wood. The center column can be a fairly soft wood, even northern white cedar will do as long as it is large enough in diameter, say a 11 or 12" top size. The treads are more demanding as they take the impact load in a cantilevered setting. A straight and strong grain free of knots at the 4 5/8" dia. tenon is needful. Also this design requires that the handrail be constructed in such a manor as it locks all the stair treads together, so the impact load is distributed to 3 or more treads, and not just 1.
Thank you for fast response! I understand every what you wrote, but these types of wood, those you mentioned are only American trees, not Europe. So, I will try to get proper softer tree for central column, and some stranger for treads... When I make the plan for all parts, I will feel free to ask you for confirmation, and until that I wish you Merry Christmas and all the best...
@@MAKMEDIASA Very good😎 Short answer, softwood for the column because it drills easier, strong material for the treads because of the load placed on them.
Hey again! So, I have my log stood up and have my small holes drilled and am ready to hog out the 4 5/8" diameter holes. I thought my Makita mixing drill would have the power to run the bit but It basically needs to be backed in and out repeatedly to do any cutting so it takes a while to get anywhere with the holes. I see you've got a big Milwaukee drill in the video..what kind of power on a drill would be best to bore these holes?
Nevermind, found a drill for the job..bent my lead screw though..looks like I need some higher quality steel.
I see now that you sell these on your website...ordered one up!
The shank on it (3/8") fits a 4 5/8" Milwaukee bit, it will go out in today's mail. It is made out of B6 fine thread 9/16" dia. threaded rod.
@@Tenonizer Sweet! Thanks, Have you had any trouble with your lead screws bending and leading the bit to wobble?
@@SWERVE191 Never had a problem with that ever, having 2 people on the drill helps, or I have hung it from overhead with a rope if I have run it by myself.
How yoy make the circle edge on stair so it fit on column??
The stair tread tenon can be cut on our biggest tenon cutter, the TC 338, sometimes people will drop ship or bring us (or one of our customers who has that machine) the tread blanks and we will custom cut the stair tenons for them, generally $25 each tread; 4 5/8" dia. x 6 to 10 " long, tapered .001 per inch
Shouldn't the last top riser be parallel with the loft as it was shown in the sketchup model? Do these comply with the current International Residential Building code?
Sorry, code calls for what I consider a functionally inferior stair system, rise/run/footprint/degree rotation all wrong unless you add a second inside handrail.
@@Tenonizer This being is a spiral staircase and not a circular one and correct me if I am wrong I do believe an inside rail does not apply but you do have to have a minimum of 6 3/4" tread width at the walk line. Like it or not even if you do not have a code official to contend with you have to be code compliant.
I shoot for a 10" tread width at the walk line, but in MN "inside city limits code" at about a 3 foot radius point, MN code calls for an inside rail but at a 2 1/2 foot radius it does not. Most of the stairways of that type I build are about 3 1/2 foot radius, or 7 foot dia.
How did you cut the tendon on the treads
The big (4 5/8" x 7"long) tenons were cut on Tenonizer's TC 338, but if you go to the Playlist "You Can Make This" on Tenonizer's RUclips channel you will find the video there about cutting "Monster" tenons; there we present a way to cut the Log Circle Stairway tenons with a $10 lathe on a table saw. If you have other questions about this, feel free to ask, I will try to answer.
Wouldn't it have been a lot easier to drill the log in the workshop before installation?
Enjoyed the video, but you skipped over how you did the tenon on the stair end. What diameter, length and how you machined it. Also as mentioned above, how you rigged the log to spin horizontally.
As a Life long Log home builder, I suggest you treat the bottom with impella rods , which are hardened Boric Acid non toxic , mold, mildew, rot and insect repellant, it crystilizes the cells!!
Yes, you are correct, as a log home builder you understand "ROT IS OUR ENEMY" and must be kept at bay by whatever it takes to do so! Our interior cement contact posts and columns have a 1/4" thick rubber/belt between the wood and cement (or something like that) not always shown in the videos but the protection is there somehow. Good of you to catch and comment on that critical issue. 😎😊
Not to nickpic.. but you built a "winder" staircase, not circular staircase. The difference would have had your job red flagged. A winder staircase is one which the treads do not cross over any other tread, where a circular staircase allows the treads to cross over any number of times. The tread height and rise are completely different between the two types of staircase.
