Correct!

I bought a traditional longbow, not a yew one (yew longbows are very expensive) but made from rattan,

Rattan? I think my grandmother had some chairs made from Rattan, similar to that

a strong wood that is quite good for this thing. I have to string / restring it, it's insanely difficult to do so and the longbow is around 76" long (I believe 120 cms / 1.2 metres?).

Inches to centimetre? I remember something like 2,5...

According to the table here
https://www.inches-to-cm.com/
2,54 in to cm is right so 76" would be 193,04 cm or 1,9304 m - larger than me.

However that seems really huge. Are you sure about the 76"? Do you use some archaic form of Inch were you live? Is your second name Odysseus if you string such a monster?
