- This video replaces the old video #3 which was not very good and I think this makes it a little clearer to understand the process of cutting the struts.

Your miter saw is sophisticated
very cool I am so glad you made this video. you flip the struts like I did on my 6v dome good job!
So helpful! You have no idea!
Thanks for sharing
Awesome!!!
Replace the orange saw insert with a wood insert. That way you will know exactly where the saw blade is cutting.
Can you clarify the last portion of the video please? Strut "B" gets cut at 12 degrees and then we line it up and cut to a point. Strut "A" gets are cut at 45 degrees on one end? do they still get lined up and cut to a point the same way? This makes a 2V dome? What is the finished diameter? Thank you!
Since you have a compound miter box just mark the center of the long point and make it with two compound cuts instead of making three.
I want to point out again that this is a great community where we all can share information and we are all here to help each other. You can go to this address to find out any strut lengths for any size dome you may want to build. It is an awesome resource!!

calvin busch Hi Calvin! Thanks for all the videos! I'm not sure if my mitre saw has the ability to cut the 63.4 degree angle that this diagram calls for. acidome.ru/lab/calc/#1/4_Cone_1V_R.95_beams_88.9x88.9
The two cuts i need are 20.9 degree ____\
And 63.4 degrees correct?
Any information would be much appreciated! Out of 4x4 Fir!
Thomas Ethan Foster Hey Tom, the angles will be 60 degrees for B and C struts, but only 54 degrees for the A strut! A struts are for the pentagon portion of the dome ONLY! Not sure where you got the other angles from. RE-watch my video on how to cut the struts and listen to my explanation. Thanks, Cal
Calvin,
Can you help me a little further on the explanation. I want to build a 45ft home using this technique with 2 x 6 wood. Will this work? Do you have any plans or instructions to go by? Thanks for a great video.

Johnny basically this video will work for you no matter what size of dome you build. 2x6 or what size of wood. but the bigger the size of wood potentially the bigger the size of saw you will need. Mine is a 10" saw so you may need a 12" for the 2x6. If you want to use a hubless strut as I do then make sure you USE SCREWS!!! I would also try to put a smaller one together first to gain experience framing it. It will help a lot. Also make sure you have someone to help you assemble the dome. It is just easier that's all there is to it! Make sure you figure how big you will need for plywood with a larger dome also. You will need pretty good size triangles for your 45' dome. Although you can use smaller pieces of plywood. I showed how to do that on one of my videos too. I forget the number. You may consider using a 4V dome if the triangles are too big as well. If you have anyother questions I'd be glad to comment on! Good luck
Calvin, I was kind of hoping you might know how to make individual triangles to assemble rather than screwing together each strut.
That will probably require quite a lot more material. If you think it would be easier that way, don't be deceived. It is NOT hard to frame a dome. But it is easier with two people. Seriously, try to build a smaller dome first. But if it is too small like say an 8' dome it will be harder to build than say a 12' or 15' dome ( first hand experience on my part!! Haha!). A dome as big as you want to build is pretty ambitious so you really should start with a smaller practice dome. But I wouldn't build the triangles first to construct the dome.
3x as much timber :) other downsides: more time spent in the shop cutting wood and making triangles. Handling an 8ft strut is a lot easier than an 8ft triangle when your standing on a ladder :)
I prefer to use tubular hubs, less cutting and its easier to assemble/disassemble the dome many times over, ideal for portable domes.
do i need a mitre saw that goes beyond 45 degrees?
+John Chapman basically yes. Otherwise you would need to make some sort of jig to make your cuts.
nope, most miter saws have 0 in the middle (90 degrees to the fence) and a swing of 45 degress each side.What you will need is a compound miter saw which allows the blade to be tilted so you can make the bevel cut ;)
You can use a basic mitre saw (no bevel function) in a pinch by rigging a jig that puts the strut end cut vertical and at right angles to the fence. Then you only need to make the miter cuts. If you allow for the blade kerf in the jig you wont need to worry about marking the centerline, just position the wood against the correct side of the jig.
Calvin what are the overall lengths of the struts you only need two sizes?
Hey Silercreek how you doing? Thanks for your interest in my information here! I may have stated that you only will need 2 lengths for your dome someplace, but I would have been talking about a 2V dome. I will include a link for you to go too and you can punch in any size dome you chose to find the lengths of your struts. It is a great resource and I have mention ed them in a seminar I have done before. Let me know how this works out for you okay? You can copy and paste it into the address bar. Thanks.

Thank you for clearing things up you were right on the money talking about how they keep some of the info so vague that website seems helpful I would like to build one when you put in the size of building is that feet and inches that's computed and is the overall length to the long points of the struts thanks for all your info it's really got me thinking can't wait for spring
Calvin yup I jumped the gun asking you questions after getting little more into that site you are absolutely right all the info is there and with the help of your video I have my plans all drawn up for my structure I now know what I need just need to give it a go thanks for the help hope your doing well really enjoyed watching and learning from you take care
am trying to figure out how to record a video from the house because I tried and it didn't work to well. But I want to let everyone know that I will be doing a series on starting a homestead this spring. I have already bought the property but won't start until April or May. I do plan to build a couple domes as well and will continue the series. Glad you are so gun hoo! Good for you!
Sounds good Cal looking forward to seeing those videos good luck with that I'm sure you will be hearing from me
Хочу себе такую пилу, не где не могу купить её.
You should go to Woodprix if you'd like to make it yourself guys.
Can you clarify the last portion of the video please? Strut "B" gets cut at 12 degrees and then we line it up and cut to a point. Strut "A" gets are cut at 45 degrees on one end? do they still get lined up and cut to a point the same way? This makes a 2V dome? What is the finished diameter? Thank you!
