First Try and Question

[kfetchen]

Hi !
So after watching several tutorial videos and playing around in Segmented Pro, I have (I think) done a simple bowl plan using Walnut and one accent ring in Maple. 12 segments, simple design. If someone can look at it and tell me it will work without me wasting expensive (in my opinion) wood. Also, my questions, although I did try and search for already posted info, my cutaway view only shows the bottom ring in walnut and the rest in maple, not a big deal just curious if I did something odd. I did use the paint feature. My 2nd question is in the summary tab, is there a way to change the header titles, Walnu shows up and I wanted it to say Walnut (previous proof reader and typo for me is a no no) and is there a way to save the typing and format when I leave that tab and then return later? Thank you very much

The cutaway view only shows the default species for each row. This is true if you’re making a feature ring, a painted segment or a tornado bowl. Its sole purpose is to show you what the bowl would look like if you cut it in half before doing any turning on it.

I’m currently on the road so I can’t open your file (I’m on an iPad). However, you can look at the cutaway view and imagine if you remove the minimum amount of wood on the inside and outside so the the profiles are smooth and that is how thick your wall will be.

If you have selected a Wall Width of the default 3/8”, it is critical that each of your rows are perfect, meaning that the SEL is exact to Mae the outside diameters match the outside profile and that the board width is at lease as wide as calculated to mae the inside profile correct. The 3/8” measurement is the overlap of wood between two rows where if the two rows are identical inside and outside diameters, the overlap will be 3/8”. As the profile tilts in or out, the 3/8” increases using trigonometry so that the wall will be a thickness of 3/8” (or whatever you select) from the bottom to the top. The exception is that towards the bottom the wall width automatically increases to allow you to transition it to the base.

If you are just starting out, you should increase the wall thickness to 5/8” for your first bowl. You’ll have to remove a bit more wood, but you won’t run the risk of cutting through the wall at a place where the rings may not be perfect.

You cannot Mae any adjustments to the Summary because it is simply a list of rows. Instead of printing this, you should click the Export button which will result in the data being opened in your spreadsheet program. From there, you can do anything you like such as deleting columns, changing font sizes, performing your own calculations, etc.

There is a tutorial you should watch that shows how I do this. The 3rd category has a forum named Follow Along Projects. The first one is a -part tutorial I made named “Open Segment Christmas Ornament.” The first tutorial shows me designing the vessel using Segment PRO and it include a part where I export the data to Excel.

Lloyd made some good points on wall thickness.
I recreated your bowl (thanks for posting the json file) in WTP. What the numbers are showing is the glue surface between each rings. imo, you have more than enough wood to create the shape and have a good bonding surface.

 

[kfetchen]

Thank you both!

Enjoy the software.
I have found I use both WTP and SP in designing some of my projects. SP has a great paint feature and 3d rendering of the vessel. Over the years I have found it does not take much to use the SP summary sheet and rebuild the vessel in WTP. WTP allows some adjustments that SP does not allow.

Happy Turning.

When I started turning plans developed with SP, I first made the vessels from #2 pine scraps. This let me see the relationship between the software flat models and my CAD (Cellulose Aided Design) solid models. Two of those experiments came out so well that I stained and finished them and they're still on display today.

Hi Mike,
How did you re-create the file? I think you must have started from scratch? I was trying to use the software again doing an urn I created in SegPro but my teacher wants to see the cutaway view and my polar graph which I don’t have. I only have the export image and the cut list spreadsheet. Is there anyway for me to get these easily? Thank you.

Yes, I recreated your bowl in WTP from scratch. I used the Outside and Inside diameter from the SP summary. Did not take very long.

Not sure what is up with the SP *.json file. I can import it, but it crashed SP when I try to open it. May be that you have a something missing or a species in your palette I do not have.

Got a question for you. What are you using a polar graph for?

If you want to try and save the SP file again I will try again to look at it.

 

[kfetchen]

I saved the file again. Not sure why it crashed. It's a very simple urn 11 rows all poplar wood. The teacher uses the polar graph to match the cut pieces to make sure they are precise before gluing the ring. I make the polar graph based on the measurements from the graph drawing which looks like the cutaway view but with measurements. He draws two lines for the inside and outside measurements on the ring so you know where to put the glue and center the ring.

I'll just try and recreate on paper using the outside and inside diameter like you mentioned.

Still no joy on your json file. Tried it on a different PC and got the same results. Imports fine, just can't open it.

It should not take you very long to rebuild the vessel in WTP using OD, ID and row thickness.

One good things about WTP is the ring view can give you a printable ring of exact size.

I’ll download the file and see what is causing the crash. What the file saves is different depending on how you’ve designed th bowl. It’s likely saved with the data but the program that opens it doesn’t recognize it. It’s the first time I’ve heard of this in 7 years so it hasn’t been noticed.

I’d fire my quality assurance team if I had a quality assurance team.
