The Setting Out Of Arches On Site

[@ingridnicholas4581]

It's amazing how with the right teacher you can learn so much more. I'm not great at anything mathematical and read a 'how-to' on this but couldn't understand it. Seeing this video makes perfect sense. So helpful especially with the segmental archway, as I'm making a shepherds hut that requires a roof truss for my 8ft x 1ft arched roof pieces! So so helpful, thank you.

Happy to help!

Top Class Mike but having worked with you for many years I'm not surprised. These videos will assist any craftsman/woman who has the need to create a project involving any of these techniques...Devoted to your career you continue to share and bring knowledge and skills to many....Congratulations on a wonderful series of most useful videos.

Thanks. I came across this because I was looking for a solution to a problem. I have a curved outside corner and needed to calculate the radius so I could put it into a 3D modeling program. Hands on in the real world it was no problem to make a template. Who cares what the radius is when all you have to do is cut some material and fit it. However, add in needing to know what that curve is and give the 3D CAD program a number to work with and now you got a problem. This video helped me to wrap my brain around it in the physical world where I am most comfortable. Good job.

Your welcome.....glad it was usefull.....

Thank you so much for providing this information on arches. You made it easy to understand.

Michael, The animated graphics associated with the layout of various typical arch forms is most useful and a great reference source. Often, particularly in stonemasonry, one is required to produce an arch with a set number of voussoirs plus a keystone. Use of dividers set at at an initial approximation to the voussoir width and then stepped off around the intrados of the arch and then adjusting the setting accordingly dependent on whether one under or overshoots the perimeter of the arch has been a method taught to us. This trial and error stepping. off approach has numerous other applications in elementary setting out and more than often superior to making actual measurements which can often lead to inaccuracies. Thank you once again for original content and clear 3D graphic production!

Glad you like it Jeff....it should prove useful to other trades apart from C&J such as sheet metal fabrication, stone masonry etc

[@billfurness6920]

Hello Michael, Nice go at this. I got 40 years in this and still learning

[@michaeldownes516]

glad you like it Bill....40 years at it myself and also still learning...

[@artinconstruction9070]

Hi Michael fello Irish man here living in Australia, we do old school restoration, I have a possible church restoration coming up with lots of gothic arches, your videos are extremely helpful, thanks a lot !

[@michaeldownes516]

glad you find it of use

[@seanlannin]

Brilliant, fantastic animations.

Glad you liked it Sean.

Amazing information. Love you ❤

[@MissPiggyM976]

Very interesting! I love the false ellipse!

[@olsonlr]

Can also do ellipsis with a loop of string and screws.

[@williamsmall2710]

Brilliant example so well explained and easy to follow

Glad you liked it

Great stuff. I have seen math formulas for this, but this better. Thanks.

Hi Michael, can you please make a video on how to do the indian multifoil arch geometrically. I can do it freehand and with guesswork... but how can we establish it geometrically so that if someone gives me a certain passage or entrance to put an indian multifoil arch in, I can go in with geometrical rules and do it just as you have presented here with these videos.

[@michaeldownes516]

I would love to do a video on a multifoil when i get a chance.....in the mean time, if you pause at 10.27min into video and visualise and arc whose center is where the larger pink arcs intersect, and radius is where blck broken line intersect pink arc.Then the next radius center is where the yellow broken line intersects the pink arc, and its radius streched to where black broken line intersects pink arc. Continue same process down to base line. You may want to reduce each small radius to aviod a feather edge between arcs. I know there are alot of variations of this type of archway....if you send me a link to an image of the type you are referring to i could see what i can do. hope this is some use...

[@billf7062]

Very informative video on setting arches. Thank you Michael. How do you establish the “springing line” for the Gothic arch?

[@michaeldownes516]

Hi Bill, the springing line in the case of a doorway would be where the vertical reveal line from the floor level ends..and the arch curve then starts,,,,this is in line with the Gothic span line. This distance from the the floor line would usually be a given on the architects plans. Some times the overall height from the floor level to the top of the the gothic arch is given....in that case you would have to subract the Gothic rise distance from your overall distance to get the distance to the springing line from the floor level.

[@billf7062]

@@michaeldownes516 Thanks again Michael.

[@oooyugi]

This is Excellent ! Thank you. 👍

[@michaeldownes516]

Glad you liked it!

[@kenchrapko3697]

Hi, in your example of a False Semi Elliptical Arch you mention the rise as 1/2 the minor access but what is the minor access ?

[@michaeldownes516]

...half the minor axis....(not access)

[@michaeldownes516]

The major axis is the longest diameter and the minor axis the shortest diameter

[@parkavenue6970]

I cannot believe what I am seeing before me! Michael, thank-you! There is so much in the world that is unknown to many people! Why has building beautiful archways seemed to disappear? Do you have a school?

[@michaeldownes516]

Glad you liked it..hopefully there will be more of these archs going foreward as the instruction to setting them out, in an animated format, is accessable on line ...i instruct apprentice Carpenters and Joiners in a training center in the west of ireland.

[@inthecompanyofcorvids]

Could I ask what geometry program you used to make this video, please? 🙏

[@michaeldownes516]

i use the animation option in power point

[@inthecompanyofcorvids]

@@michaeldownes516 Thank you, Sir, very much appreciated.

[@atubeviewer4942]

Does anyone know - What kind of math app is needed to calculate gothic arches like these? I have not found 1 app that does gothic arches.

[@felipesants8936]

MICHAEL , HOW DID THEY FILL IN THE CELLS BETWEEN THE ARCHES?

[@michaeldownes516]

Hi Pelipe, did you mean joints between the cut stone that form the arch?

Hola Michael es una buena idea pero sí se puede hacer la traducción en español
