A 17.5 gpm 2 stage pump would be a good match for a 4" cylinder, 9 sec, but with a 5" cylinder the cycle time is 13 sec. Most of us would not be happy with that wait. A 22 gpm = 10 sec, closer, 28 gpm = 8 sec. This is what we want!
Producing what everyone else is doing will not give you a real nitch in the splitter market. Most of us are willing to pay the difference in the price of the pump for the improvement in speed. Remember you are not just competing with the hydraulic splitters but also with the inertia splitters like the Super Splitter which has a cycle time of 4 sec. The inertia splitters cost twice what your "22" ton unit does but folks are buying them because the increased productivity pays for the difference.
Lots of great suggests given in prior posts. Whether others are doing the same way, we the better informed want the little extras to have better posture, decrease resistance/heat generation & better oil cooling.
- Taller work height
- Wedge at the end of the beam, not on the cylinder
- Out-feed tables which start at least 4" before the wedge so the wood is over it & will not be pushed into it. gaps to allow debris to fall through.
- Use sweep elbow vs hard 90 degree fittings & no lines smaller than what comes off the pump
- Larger reservoir
- Consider having an oil cooler option.
- Log lift
- Adjustable height wedge with quick change wedge options
- Horizontal wedge wings only beveled on the upper surface so the splits are not forced down into the out feed table. (Don't put the little vertical tabs at the end of the horizontal wings, but if you do, only on the upper surface).
Tongue on the out-feed table end or on the cylinder base end. This is a question you might want a poll on. There are advantages to both.
- If the splits are going towards the towing vehicle, hitch under the out feed table area, it can make it easier to fill the towing vehicle.
- If you will be splitting into a pile or onto trailers/multiple vehicles, then having the hitch under the cylinder base area would work better.
(These are assuming you want to be able to leave the splitter hooked up to the towing vehicle.)
Hope as you plan future models, you will consider these suggestions.
