Ig, that's barely a healthy log splitter cylinder. That's not only NOT
'huge', it's not even a moderately-sized cylinder. A lot of DIY guys would
find use for a cylinder that _small_.

That's too small a cylinder for 500 ton, unless its a toggle press.


Huh? I see splitters on sale which are only 5T to 42T ($7k)
Where the hell did 500T come from, Karl? That _would_ be a large
splitter. "Add 16 stumps and press button for 128 splits of wood."
I love the automatics, which drag the log into the splitter, cut it as
precise length, then split to 8pcs per round...every 5 seconds.

I thought maybe Iggy quoted the cylinder size wrong. A 500 ton
conventional press has a HUGE cylinder diameter with maybe a 7" push
rod. Iggy said in anther part of this thread that its a toggle press.
This style used a small cylinder (like 7") pushing on a "knee" to
provide a huge mechainical leverage and get the 500 ton force. Iggy's
press is not real old, toggles showed up in the 1980s.
