How to fit scales on a folder kit with two bolsters

Thanks Taximanny
I have been placing a piece of copy paper flush to one bolster and scribing a line using a pencil rubbing on the top edge of the other bolster. It works ok, but didn't know if there was a better way. Thanks
 
Disk sander with a 90 degree work rest. Match one side to the correct angle so that the scale width fits. I usually make reference marks on the second side, but a lot of it is by eye. After that, it's grind and check and grind and check, going slow, until it's right. Careful not to overshoot. There may be a better way, but that's how I do it.
 
If you start fitting with the bolsters still flat you can place the scales above the bolsters, flip upside down and sprinkle chalk or graphite (depending on the scales color) to mark the lines. Than cut a bit oversized and slowly drive home.
Slanted bolsters are easier since you have more room to get the angles and then wedge it tight
 
I do as Jason does. One thing that makes fitting a lot easier is to have an angle between the two bolsters. If they are parallel, it is much harder to get a good fit. With an angle, you fit one end as Jason said, and slowly match up the other end. By having the scale material a bit wider than needed, you sneak up on a wedge fit into the angle. If you sand a tad too much of in fitting ... no problem .. the scale just slides a tad farther into the pocket. Once it is snugly fitted, you can mark the screw/pin holes, trim off the excess scale material, and proceed with the assembly.

The divergence from parallel in the two bolsters does not need to be much. A few degrees will make fitting much easier, 10-15 degrees makes it simple. Only one bolster needs to have an angle.

The same method above is very important in fitting dove tailed bolster/scale assemblies. You are dealing with two angles, and the wedging fit is even more needed.
 
Of course, if it's not an integral bolsters construction you could solder the second bolster only once you have the scales profile ready
 
Stacy, thanks for the details. Your explanation and attention to detail is most helpfull. I tried your/Jason's method and it worked great. I just kept the disc running and shaved little by little until it fit.
