im building a log splitter and looking for advice on whats the best ram to use 2 small rams or 1 big ram?
i was hoping to go with the 2 small rams because i have some buried in the nettles round the back and would like to put them to use, they are a identical pair and the rod size is 1.5" and cylinder is just under 3" and the stroke or length is about 2 foot what do you lot think would they be beefy enough if mounted side by side? i'll try and get some pics of these rams up
First of all, we do not have all cards in the deck face up. To many assumptions about the back ground facts. If that can of Heinz beans is a 15oz can, its diameter is 2 7/8". The cylinders on the image seem to be 1/4" less diameter than the can....
The cylinder bore could be closer to 2" than 2.5"....
Even if the two cylinders combined will match the splitting force your splitter requires, I would try to trade them for a larger cylinder.
It is easy to think that two small cylinders will push more tons than one larger cylinder. But it is all about numbers and math.
If these two is approx 3" outside diameter, the should be 2.5" bore. It is the cross-section are that matters for the splitting force. The cross-section area is the square of diameter by Pi divided with 4, and that equals 4.91 sqi per cylinder, 9.82 sqi for the two combined. A 4" bore cylinder will have 12.57 sqi cross-section area....so your dbl-cylinder project will come out almost 30% less force-full than a splitter with a 4" cylinder. With a max 3000 psi pump pressure, these two will push max 14.8 ton.
A 4" bore will push 18.8 ton.
Also combined the dbl-cyl setup will make up for more friction losses than one single 4" bore cylinder...
But as I said above, we don't even know for sure the true dimension of that can of beans....
