Some of my next jobs are the doors and bonnet sides.
They have double curves for which an English Wheel would be handy.
I had a heap of scrap fence posts, so I made my own.
It still needs a few tweaks but it is already useable.
It's massive. It's twice my bodyweight, over 2 feet taller than me and has a 38" throat.

The good thing is, it owes me way under £100. Not bad considering the rubbish you can buy for £200.
It took a few weeks to build..... I just wish learning how to use it will be as quick.
