Measuring holes center to center

[William McCormick Jr]

On shelfs I always measured between top and bottom, added thickness of shelves to go inside togather, subracted shelves thickness from inside length and divided by # of spaces beween top and bottom. Is this basically the same as what you're saying WM?

Yes basically I believe you said the same thing. I just say one more space then you have shelves.

This is something that I actually wrote. It is a cool program for spacing. It runs in General Cadd.

I took my 2'square and my tee square to the drill press and drilled a hole the size of my carbide scribe at every inch on the scales. this makes it alot easyer to lay things out . also use a piece of 1/2 copper and a (couple of ground clamps used by electricians for grounding rods) drilled a hole across from the clamping bolt and soldered a nail in the holes. now I have an infinete tram used for marking .

I get the hole drilling but what is this copper used for? Can you get a pic of it. I was thinking about putting my square on tne mill for the holes but I can't picture the copper piece. Thank you

Ill get some tommorow need batt. for the camera.

[welderman1]

cool

[asemaster]

cool

I have to find out how to make my pic. smaller to fit ? they work on the other sites?

[welderman1]

pm it if you want

[William McCormick Jr]

They make something similar, except that I have only seen them to about six or eight inches long. But they are nice. And usually you do not go over that size.

I used to use a pair of veneer calipers to scribe with. What ever they are made of is tough stuff. But you really should not use a good pair for scribing.

I think this is what was being described. It is in the attachments.

Here's a good way to divide a straight line into equal spaces. Don't know if this is the right thread, but it hardly deserves its own

[Brett]

Not everyone has CAD (Wish I did) , but everyone has Excell,

I've written a little spreadsheet that will work out your centers and number of balusters for both stairs and level.

I use it every day, I do balustrading for a living.With a bit of tweaking you can let it work out your posts , post centers, balusters. baluster centers , baluster length, quantities and pricing .All you put in is angle , lengths of runs , fall and stair angle and thats it.Took me a few years to refine it but it works great.

How do you put an Excell sheet here?

Just noticed your message dave .
Will post it when I get to work tomorrow .

I never look at my messages

It will be set up for 19mm balusters and 32mm legs but you can play for your requirements.
Or I'll be happy to do it for you

On shelfs I always measured between top and bottom, added thickness of shelves to go inside together, subtracted shelves thickness from inside length and divided by # of spaces between top and bottom. Is this basically the same as what you're saying WM?

Similar, except your way works whether the top and bottom shelves are present or not, WM's only works when neither top nor bottom are present.

The thing that bookshelves often do is put the bottom shelf 50mm off the ground, just enough to make it hard to clean under but it does make the shelf sit better on hard floors. So you have to subract that 50mm first and don't count that space as a shelf. Likewise it's common to either put a flat top shelf on, or drop the top shelf 50-100mm so you can stack stuff on top without it sliding off the ends. Shelving with neither top nor bottom is IME rare.

You have mail Dave

Test 2:


trying to get a Excel sheet on the board

[asemaster]

here are the pictures of the tram that I came up with ,remove the bolts drill hole through center and solder in the pins then you can use any length 1/2" rod you want to get a good mesurement.

[joethemechanic]

Any size up to the shortest leg of the square.

Here I made a drawing to show how.

Every time I try this the nails bend when I try to drive them into a piece of plate.

I must be doing something wrong

[Brett]

Did you get my emails Dave?

TSOR, I have spent 20 minutes trying to get what you've laid out and I just don't get it. Do you fix a single point to draw the arc? Argh, what am I missing?

[denrep]

6530, Can we dance 'till TSOR shows up?

Set two points, (nails for example) with the outside spaced the same distance as your desired circle diameter.

Use a slight pressure on the square's corner as you guide it around the points.

I know what you're thinking... "It's just gonna flop over". It doesn't; try it.

I have some carpenters doing a little work. On the last job they did, I mentioned to the guy who referred them that they showed
up without a square. He must have repeated it to 'em, and I think it sunk in, because this time they have about 10 squares piled
up on a table in plain view!

It's at the end

[TSOR]

Right on!

Great vid!

For laying out small holes patterns I use a caliper and measure the inside and outside and transfer each measurement to my work piece.

to divide any distance into any number of segments:
draw a random line and connect it to what you want divided.
use any dimension and mark off the number of needed divisions (7 in example). copy angle abc at each mark.

challange: use only a framing square and pencil

Now, that's COOL!! You made it into a rise/run solution with the sloped line. That's neat.

[Tom Kroscavage]

To lay out even holes fast scribe your half inch all around your metal hold your steel rule on one scribe line move the other end of the rule diagonal untill it reads a multiple of the spaces between the holes. Then transfer your measurments to top and bottom. Already posted

The fastest way is to get good at walking your dividers. I could lay out ricks holes in about twenty seconds with a butt gauge and a pair of dividers.
