A Historical Question

[jr45acp]

In reading the threads of late on grinding and obtaining surface grinders, I began to have some questions. In the days before surface grinders were around, how were "ground" surfaces achieved? My immediate thoughts were draw filing and the final finishing with a lapping plate, or possibly scraping. I'm certain that I've overlooked something very obvious though.

Can anyone (Hey Forrest) provide a historical perspective on this? I've got way more time to do it the old way than I do space or money for a surface grinder.

I don't think there was a need to have precision ground surfaces "Way Back". I know Henry Ford was using crankshaft grinders at least back to 1906. The engine flat surfaces were also being ground so you have to go back before that.

When was the first patent on a surface grinder?

I don't know about a patent but you may find this interesting.

Talk about outsourcing...

In many ways the first major machine "tool" was a grinder. The Grist Mill and then the wind powered mill. Some times I wonder just how "flat" the stone wheels were

Grinding wheels and grinders have been around a long time,did you know the segmented blanchard type wheels pre-date the common vitri-bond round wheels?

Hi Dave, not working on anything just yet. Was just pondering the issue.
