Building a Safety Squat Bar!

Hi guys! I was wondering if any of you know how to build a ss bar. I know some of you will think: “Go over to EliteFTS and buy one, you cheapskate!”, but the thing is that I live in Iceland and would have to pay upwards of $500 for shipping…

So…

I was thinking of using 1 1/2" tubes with a 4mm wall for the bar, 150cm between the sleeves and a 30° angle between the handles and the sleeve camber. I was also thinking of 35cm handles and 35cm between the handle centers and a 15cm camber. I know this setup wil be somewhere around 35-50kg, but I’d rather have it sturdy than having it bend around my neck.

How does this plan sound?
