George,

In case my explanation didn't make sense, here is a quick sketch of the dimensions of the 577/177 test fixture layout.

Everything is in inches.

Tom,

Perfect! Just what is needed. I'll share a full scale PDF later today.

Gang,

I’ve taken Tom’s dimensions and converted them to a scale PDF. ?I then printed the 1:1 drawing on a laser printer, cut it out, and dropped it on top of a 177 test fixture to test the accuracy of the drawing. ?Using two consecutive images as different Photoshop layers I was able to set the opacity of the paper cut out to see how it compares to the actual location of the holes on the test fixture. ?I uploaded a series of pictures to TekScopes.
?

?
The full scale PDF was uploaded to TekScopeArc2. ?If you print it out be sure to set ‘Scale’ to none.

WATCH OUT FOR PAPER SHRINKAGE ON A LASERJET PRINTER! This can drive you nuts until you realize what is happening.

The heat from a Laserjet fuser roller causes the paper to shrink 2% to 3% as it is being printed. This is due to the moisture content of the paper which the fuser bakes out of the paper. To get truly accurate drawings from a laser printer you have to pass the sheet of paper through the fuser 2 times before printing your drawing on it.

To do this I use any word processor to print a blank sheet of paper. Then I reinsert the sheet into the manual paper tray and print a blank page on it a second time. After passing through the fuser two times the sheet won’t shrink anymore.

Then, and only then you can feed it into the manual tray and print your drawing on it. Now it will be dimensionally accurate.

InkJet printers do not have this problem. A drawing prints out perfectly each time on an inkjet.
