I have been looking at Honda gx engines for a unique new DIY mobile bandsaw mill build.
Non-trailer so I will design it to be moveable in two or three wheeled/lifted pieces by one person.
I've designed the basic system; it's just two rails that secure at each end of the log, at each corner there are feet that drop down to prevent movement, so the log and rails become one sturdy mass, then the bandmill part simply wheels on to start milling.
Simple farm jacks are then used to quickly raise and lower each end of the log if need be, I already do this while chainsaw milling.
Still want to cut up to 1.2m cuts in hardwoods at reasonable speed so I'm needing at least 22HP if not more.
Because I'm on a budget new engines are not an option.
Would it be possible to simply use 2X identical (used) honda gx340 engines with the throttles linked?
For that matter why not have 3X or 4X engines, why is it that nobody seems to ever pair up engines like this for more power on machinery instead of one heavy lump?
I'd run identical v pulleys and belts from both to one shaft, using the generic gx 2:1 clutch gearboxes that bolt straight on.
Slightly decreased power to weight and efficiency compared to 1X engine, for example a GX690, a little complexity too but despite that surely someone has attempted it?
I'm grateful in advance for anyone willing to share constructive knowledge and insights, or even experience of this.
