I will be using the other half's Jaguar 405 sewing machine with a walking for attachment. I did I test with 2 layers of 1.3 mm leather and worked fine will have to do another with 4 layers and see.

I would also do a test in combination with the kevlar lining and thread that you are plan on using. Personally I think the domestic sewing machine is going to struggle if it will do the job at all. Remember the thicker the leather the better the protection. Yes the thicker the leather the heavier weight wise the jacket will be but the last time I dumped a bike in a bend the pavement burned through the chaps, jeans, medium duty leather jacket and the 4mm thick belt I was wearing. Road rash is a nasty thing.

agreed, road rash is a very nasty thing.

personally, i would not go any less than 2mm, and even heavier, or doubled up in key areas, like back, shoulders, elbows, etc.

My plan is to double up in areas so would be around 3mm in key areas, aswell as armour inside to the shoulders, elbow and back

I'll be surprised if a domestic machine will handle that (although some of the old Singer cast iron ones might). The Jaguar is listed as a lightweight machine and the so-called "walking feet" that domestic machines use is a far cry from a proper walking foot. I reckon it will struggle with more than a couple of layers.
