Summery Page Question

Holger

On the summery page in Woodturner Pro how much is allocated for the saw blade kerf and for the glue? Is there a way of changing the allocation to adjust for the blade i am using to cut my wedges?

Another program i have used allowed me to set the kerf to .10 inches for a thin kerf blade, and also set my glueup to .01 inches.
 
In WTP you can set the saw kerf based on your blade thickness
Go to File / Options
in the option pop up set your sawblade kerf.

I tend to select Imperial decimal inch or metric for the numeric display. If you choice any of the other fraction options the software round to the nearest number.

As far as allowance for glue, there is no setting for that.

Sorry my error. I was referring to Segmented Pro. When I am cutting 3 or 4000 pieces it starts to add up. I want to get as close to actual length needed per wood type.

Thanks
 
SP has a default kerf of 1/8". It cannot be adjusted.

Looks like for what you want to do WTP would be the better solution.
The other would be to export the SP summary to excel and set up your own math for board length and glue allowance.

Keep in mind you should add 3 to 5 inches to the board length in both programs for safety.
 
I'm in the middle of my biggest project to date (1,152 segments) and I also wanted to be sure I had adequate material.
Because I felt like it, I did calculate it myself as you just suggested. The technique I used was:

(Short version)
Find the average segment length for each ring, including the kerf.
Multiply by the number of segments and add a handle.
Multiply by the board width to get the board area for each ring.
Sum all the ring areas for the required material.

(Engineer version)
/* Data for each ring */
NominalDia = (OD + ID) / 2
SegmentCount = 12
HandleLength = 3
Kerf = .128
RingBoardWidth = (OD - ID) / 2

SegmentIncludedAngle = 360 / SegmentCount
SegmentCenterLength = NominalDia * TAN(SegmentIncludedAngle/2) /*beware of radians vs degrees in Tangent*/
RingBoardLength = HandleLength + SegmentCount * (SegmentCenterLength + Kerf)
RingArea = RingBoardLength * RingBoardWidth

TotalBoardFeetNeeded = SUM(all the ring areas) + some for waste and screwups!

I think it's easier to trust Lloyd's answers.

I purchased what my calculations said I needed and I have just a little left with the gluing up completed. (Yes there were a couple screwups.)

I think this is a reasonable request. I’ll add it to the new version of SegPro I’m working on. I hope to have it done for SWAT in Waco, TX in late August It is a major effort, though, which has touched almost every line of code so there is a LOT of testing to be done before it can be released. I also have to redo all of the video tutorials. If ever a tutorial doesn’t match what is in the current release, it ALWAYS leads to support calls.

One thing I can promise is this - you’re going to love the new interface. No more cropping and saving an image when you save a plan because the UI does it all for you. Now you will name all of your plans so printed documents will have names on them. If you want to change the category or the images saved with the Plan, just save it again with changes. It’s far faster and easier. Once it is saved the file will be 90% smaller than it was before saving.

If you are doing 48 segments or more, you might be using an indexing system. If so, the Rings View has no value to you so I’ve come up with a High Count printout that will be a lineal look at your segments. There will be 8 columns and each column has 48 rows so if you’re making a 48-segments-per-ring bowl, each row will consume one column. It will have the segment number, a small rectangle painted with the species, and the first character of the specie name since some species have similar colors. Since it is often easier to build a ring by starting with every 4th segment so that when dried, you can go back and add the missing three segments quickly and take a cumulative error off the table. To help with this, every 4th row number has a red square around it. Every new row is a column break.

I have deliberately packed as much content per page on purpose. High Count vessels might have 15,000 (or much) more and it is necessary to reduce the number of pages required for the report. I think you may want to cut this into strips or at least glue a row and then cut it from the page.

Here is close to what the finished report will look like. I have changed spacing and sizing to allow a bit more space between the columns.

It’s interesting to note that you can look at this page and see the painted design of the bowl.

This will be a free upgrade to all current users of Segment PRO. I do intend to have a tip jar for those who appreciate the effort and would like to see additional free upgrades in the future.

My international customers are going to be very happy. I’ve sold in over 40 countries but everyone that buys gets the software in English with video tutorials in English and very poor support for metrics.

Now there will be a drop-down control with five different languages and as soon as possible, I will have video tutorials in different languages and host them in a Woodturner PRO channel in local YouTube servers. The new Cutting Summary in metrics is all in millimeters and it is super simple to read. I also did this for the non-international version and the new Cutting Summary is as good as it was bad before.
 
I print a copy of the paint screen and take that to the shop with me to build my rings. Works great. Very much like your chart. Looking forward to seeing what you come up with.

You'll be pleased to know that I have added a Quantity Estimator to the new version of Segment PRO which I am referring to as the Turbo Edition.

Although it is impossible to know how you will buy or remanufacture your stock, I think I've done this the only way that you can make a reasonable estimate which is doing it by cubic volume. It works like this:

For each row I calculate the cubic volume of a single segment. To make this realistic I add a saw kerf (you can now specify the kerf thickness, too) to one side of the segment and to one end of the segment. This footprint extruded to the thickness of the row gives you an exact volumen of one segment. This is multiplied by the number of segments of each specie used and that is accumulated for every row yielding a total cubic volume for each specie.

I then convert this to board feet using 4/4 stock at a board width of 6 inches. I then use the thickness of the rows plus a sawkerf to determine how many slices you can get from the 4/4 stock. Unless your segments are super thin, this will result in one or two slices. If you can get two slices from the board, I calculate that you can get 80% usage of the stock. If you can get only one slice, that drops down to 40%.

That shows how many board feet you will need and then I add 50% for waste and mistakes.

The bottom line is that it is far from perfect which is why I have refrained from adding this through the years. Still if you keep track of how much you use and compare it to this report, it will give you an idea of how the apply that knowledge to future reports.

Here is a sample printout:

I hope you find it useful. The startling thing is how few board feet you need to make a high-count bowl. But once you realize that the size of the bowl is small and it is mostly air, the actual volume of wood in the bowl is not very big.

I am now in the Beta Testing phase and plan to show the new release in Waco at SWAT at the end of August. There will still be more work before it can be released.

On the summary page, are the numbers in metric or imperial. Seems to be a combination, or this old guy is just getting senile.

My experience with the current version of SP is it can get confused between imperial / metric when you pull up a plan done in imperial and then go to Settings / User Defaults and make a change to metric. The same is true if the original plan was saved with User Default metric and wanting to change to imperial.

To avoid this if I wanted to change a plan from imperial to metric I change the User default before loading a plan.
If I have already pulled up a plan, I do a Reset All, then change User default and reload the plan. Seems the summary table is correct then for the desired unit of measure.

If you look at it in metric, you're going to fine that some numbers are in imperial. So here's the good news - you're not losing it at all!

Here's the better news. Wait til you see the new CutList in Turbo Segment PRO. I spent a long, long time making sure it all made sense from an international perspective. Want to see for yourself. Here's a page from a Painted Segment bowl. I even put it in French or you can have it in four other languages. Here is the user interface with one of Tom Lohman's Bowls:

And here is the Cutlist after switching to Spanish:

All in millimeters and as pretty as you please. I'm at the start of the beta testing phase and since this is such a major upgrade it will be in beta for a few more weeks. I'll be sending out a newsletter when the new version is ready for release.

And if you want to know how much wood to buy, well it will tell you that as well. This time in English:1754190888558.png
And if you're going to use an indexing jig, there's a printout that shows you the segments in the order you will apply them with every 4th segment identified if you like to glue them first to setup anchors.

Good news for everybody. Even though I have six months of effort into this release, it will be a free upgrade to all Segment PRO users.
