Default Hydrulic system questions

What is this arrangement on my sawmills hydrulic system?

1st picture...
Pressure gauge? There is a handle to the right on the end that says "pressure increase"
There is also what I think is a shutoff valve under the pressure gauge?

#2 I assume this is a relief valve or regulator of some sort?

I thought the supply and return sides wpuld be separate but they both run through those fittings.

Flow control and pressure relief. Never seen ones that old.
Do you have a hydraulic drive for the carriage?

Don't know much about Hydrulic systems. I thought I had dealt with some old shit. I think the "Stone Tablet" manuals are available from Moses.com/manual

Yes. That's exactly what this setup is. Runs a spool valve and that runs a gear motor that runs the cable drum for the carriage.

What an abomination you’ve got into.

I still say walk away from that thing, it’ll be your best option in the long run.

Why do you say that?


The hydrulic carriage drive is a Tyrone Berry model SMA 213. Purpose built for what it does.

It could very well be purpose built.

Between a swing saw you’ve already said you have no plan to use, a circular mill that eats wood and makes sawdust, and uses a HUGE chunk of real estate, a driptroit that excels at making noise and oil spills and not much else, and all of it being a huge project just to think about making it ‘useful’, I can’t see why I would suggest to walk away from it.

There are several here that have seen what both circular and band mills can do, (myself included), and I haven’t seen too many comment that this was a good idea, or that they are excited to see it in action.

Hey, whatever floats your boat I guess, but I’m a vote for a small portable band mill. Heck, if I was still in Onterrible, not only would I look at the option, but I’d maybe look at electric. If it would run off a portable welder/generator, than it’s one less ICE to maintain, and simply look after the welder instead.
