If you have ever got in a muddle working out the measurements of a mount you want to cut, here is a useful tool that will calculate it all for you:
This is a program written by William Saywell © and it creates a template, with measurements, that you can use or give someone else to cut a mount exactly to your requirements.
Click (or right-click) on the above link to download and save the file to your computer. This is an .exe file, which means that it is an executable file. If your anti-virus or firewall program starts giving you dire warnings about downloading it, don’t worry – this is a safe file and it will do your computer no harm.
When it’s saved to somewhere on your computer, just double-click on the file and it will launch on to your screen.
It’s self-explanatory to use and a very useful tool. All feedback to William, please!
