Ned Simmons fired this volley in
:

They're not conceptually complicated machines, but not something
thrown together from off-the-shelf parts, either.

Commercial ones. But the implication was that he built this himself, not
very precisely.

Unless he has a foundry out back, likely he used stock parts.

He also made obeisance to the OP of the fact that it wasn't very precise,
just "smooth".

You did read all that, right? Your comment was in that context?
