Agreed you don't need a ''proper jig'' but it's ''proper'' hassle without. Anyone would ''struggle'' to build a decent frame without. Building a home-made jig is possible but a project in itself. You can also buy relatively cheap measuring equipment as Perks suggests but again this makes the job ''proper'' ''admin'' as I like to call it. Still we are pretty much all here for the love of it so nothing wrong with giving it a go.
