Fresh install of macOS Lion on Mac Pro 1.1

[Guest Thabto]

Hi.

I recently found a Mac Pro 1.1 in storage. I have since upgraded the RAM to 16GB. Hard Disk is missing. How can I install a fresh macOS Lion to a new Hard Disk. I do not have another Mac around. How can I create bootable media? Let me know.
