Hi, I have a steel ruler that measures from the centre out to the ends, 150-0-150 (on the other side it is normal, 0-300). The company that supplies these has a smaller size than this but not a bigger size. I was hoping for a 600mm ruler that measures 300-0-300). Does anyone know if there is something available that would come close to this? I think they are called centre find rulers, but they are handy for other things like quick multi measuring with sheet metal! Thank you for your time!

try it and see get a ruler and measure that is your best depending on what you want to change , most steel parts might fit because they have been using the same frames foever

This could be several problems. Check the graduated ruler, and the smoothness of the carriage travel. When you slide the carriage side to side it should have some resistance, but not be jerky. Shine a flashlight to the left of the inside of the printer and see if you see rubber dust at the end of the drive belt. It could be the gear that has worn out.
It also might be the sensor that measures the paper width and cleanliness of the print surface. Clean the print surface.

Use a ruler to measure the lengths of the sides and a protractor to measure the angles. The scale factor is the lengths of one divided by the lengths of the other.

Draw two chords of the circle (any two chords will do, as long as they aren't parallel). Construct perpendicular bisectors of each chord. The center of the circle will be where the two bisectors intersect.

You might have the outfeed table lower than the blade. If the outfeed table is adjustable, then you can check it easily with a steel ruler. With the Power OFF, lay the steel rule on edge on the outfeed table so that it hangs over the blade. Rotate the blade by hand in the forward direction. The blade just just barely touch the ruler. If the ruler is bumped up and pulled forward by the blade, then this is the problem. If your outfeed table is not adjustable, then you need to adjust your blades. If this is not the problem it may be that your wood is not uniformly dried.

If you are looking to purchase a new watch, you have likely seen that there is a measurement for the watch case. This does not mean the box which contains the watch. The watch case is the space between the two arms that extend above and below the watch where the band attaches. The end of the band will fit in between the watch case. You will need to know this measurement both in purchasing a new watch and in looking for a replacement band. Often, watch makers give this number in millimeters, and for that reason, you will need to use a metric ruler to make the measurement.
jQuery('.intro .thumbnail').each(function(i,e){ jQuery(e).find('img').one('error',function(){ jQuery(e).remove(); }); });

1. Find the watch case. It is the space where the end of the band attaches to the watch face. Refer to the image for a picture of the location of the watch case.
   
2. Using the metric ruler, measure the distance from the inside of one of the arms to the inside of the other arm. Watch makers use the inside measurement when creating their watches, not the distance from the outer edges of the arms.
   
3. Write down the measurement on the piece of paper. Measure the other watch case, but they should both be the same measurement.

jQuery('.article ol .image').each(function(i,e){ var $this = jQuery(this); $this.find('img').error(function(){ jQuery(this).remove(); $this.remove(); }); });

Not enough info, a steel ruler could be in 64's of an inch, a steel tape measure is usually in 16's of an inch but some are in 32's of an inch until you get past the 12" mark.

Flex line screws into the block where the two steel lines for each side brakes are joined.

no you have to replace it. very common.

I don't know about Signwizard but if Corel Draw is the problem, this might help. Double click on the ruler or...Go to tools and open the Options dialogue box. Click Document then click Guidelines then Rulers. The right panel should show a button the says Edit Scale. Click that. Make a note of what's there before you change anything.
You can calibrate the rulers to real-world distance too.
1. Click Tools Options.

2. In the Toolbox list of categories, double-click Toolbox, and click Zoom, hand tool.

3. Click Calibrate rulers.

4. Place a clear plastic ruler under the on-screen horizontal ruler.

5. Click the up or down arrows on the Horizontal box to match one unit of measurement on the on-screen ruler with one unit of measurement on the actual ruler.

6. Place the ruler beside the on-screen vertical ruler.

7. Click the up or down arrows on the Vertical box to match one unit of measurement on the on-screen ruler with one unit of measurement on the actual ruler.
