I am trying to build a table with tracks to help me hold things down, I have a measurement between the 2 outside tracks that is 49 13/16 I would like to add 8 equally spaced tracks between the outside tracks and for the life of me I cant figure out where to place each track to have equal space between them. can someone that has more math skills than me help me figure this out?

Thank you

Your tracks are going to be 5-1/2” apart, too close in my opinion
Maybe just put one in the center and lay them out to see where you’d like them

Convert 49 13/16” to a decimal and divide
by 9. The resulting number will be the
distance between the centerlines of the
tracks.

Thank you for your response, however using 5 1/2 makes the space 4 1/2 between the last 1 and the 1 on the edge

loren, if I did that correct it comes to 5.534722222, well I have no clue what that is on a tape measure. LOL this is where I am having the issue

I am wanting to lay 10 t tracks down and have mdf between each track for this table, I am trying to figure out the width to cut the mdf so it will all be equally space, therefore I need to equally space the distance between each t track. the track I have are 3/4 wide. I hope this makes sense

Split the 13/16 between the first and last track and the respective edges of the table then lay the remainder out with 7 inches between the leading edge of each track and the next.

Or make that 7 just a touch less than 7 1/8 and make that the gap between the inside edge of the outside tracks and the center of the next track in and that same gap center to center for the interior track spacing.

e to m=inside edge to middle, m to m = middle to middle, m to e = middle to inside edge

Sorry the pics are so small, did them quick since i couldn’t work out how to get a hard line break in this editor.

I’ve done this with a drafting divider. I figure
out the distance and set it as accurately as I
can on the divider and then “walk” it on the pins
to check and readjust it until I get the even
spacing I want.

The difference between a divider and a compass
is the divider has points on both legs.

Available width between two outside tracks is 49 13/16ths. You want 8 equally spaced tracks in the middle. So, with 8 equally spaced tracks, you need to cut nine filler strips of MDF. The tracks are 3/4 wide. Cut the MDF strips to a width of 5.535-inches wide. Subtract 5 from 5.535 and you get 0.535 inches. How do you convert 0.535 inches into sixteenths? Multiply 0.535 times 16 = 8.6. Hard to read between 8/16ths and 9/16ths. How to convert 0.535 inches into 32nds? Multiple 0.535 times 32 = 17.1. So, 5.535 inches is very close to 5-17/32nds. Nine strips each 5-17/32nds wide, will get you to 49.781 inches, about 0.003-inches less than 49-13/16ths.

Oh. Here’s another way to do it. Zero your
tape to one edge and then angle it until
it crosses the distance measuring a multiple
of 9. You may want a helper to hold the one
end of the tape and “burn” at least an inch
so you’re measuring not from the end but
from an inch marking. Pivot the tape until
it lines up with the multiple of 9 (+ the inches
you’re burning), then mark off the intervals.

Make two sets of points this way and then
you can draw straight lines connecting them.

You can also just mark off a long piece of
scrap cut to 72” in 8” intervals. 8×9=72
so that will give you 9 more or less equidistant
sections with 8 lines in between them.
Work carefully and a pretty accurate result
is possible.

Loran beat me to it. This is the easy way. Minimal math required.

Or, you could use a 54” scrap (6×9=54”) and mark off spaces every 6” getting you 9 equal spaces :>)

WOW, thank you so much to everyone that has tried to help me. I am going to get this figured out with these suggestions. I know this may be so simple for some folks but for some reason it has really stumped me. I does not have to be perfect but i would like it as close as possible and I think with these suggestions I will be able to satisfy my OCD
I will post an update once I have it conquered! LOL

Thanks again everyone

dawgs, it reads like youre building a worktable to hold things while ya work on them. if thats right, i dont think what youre working on is going to care if the spacing is off a bit.

TomSteve, LOL, you are correct whatever I will be working on has no idea. my OCD has got the better of me with this and I will know the spacing is off. I do think with other members previous suggestions has allowed me to get within a bearable tolerance for me.
Loren I had very a little confusion of your last suggestion about running the tape diagonal, however I studied it a bit more and think I may have what you suggested figured out. I also have been doing some other figuring and I think i May have it within an I/8 which I think i can deal with that.
We will see after i her Home and try these things

To make these calculations easier, I installed a fraction calculator on my phone. In the Android play store it’s called Fraction Calculator Plus. It’s a free app.
