For the center of the stream and possible supports, the water will not go much higher than the picture. I picked this spot because the water will rarely even get close to the bridge itself and usually will be halfway or less up to the bridge itself.
I have looked at the trailer route, and may do another bridge based around a trailer, but people around here want a mint for their junk. Part of the west coast extra cost tax I guess.
Your bridge frame is about the specs of my beams (smaller beam is 5" on one end and 7" on the other, similar to a 4x6). Free span will be about 12'.
I am sure you used PT beams.
I am thinking of burning the outside and then putting a natural oil on the fir beams to help preserve them...
I am wanting to build an ATV/Riding mower creek bridge with some of the materials I have lying around.
The bridge would be 16' long and 4' wide, with an unsupported portion of about 12'.
I have been toying working with a windfall fir tree that I cut in half for the beams. These are shown...
Cleaning up the property from poor practice logging done 15 years ago. They left massive piles that were supposed to rot, but should have been smaller and more spread out. I’ve had to torch some of them just to access areas. What a mess!
Another update. I had a chance to take the unit with my old Honda ATV over some really thick 2'+ tall fescue. It did ok if I went really, really slow. The right mower tended to stall out a lot. I think it could not discharge to the side very well (there is a 2X6" there that is the frame) and...
I adjusted the governor and that improved things a lot. However, it now surges at high RPM. I tried to set it at about 3600 RPM, but it is hard to tell from the surging. At idle and in the middle throttle, no surging at all. Thoughts on what to try next? Here is what it sounds like.
In this video you can't hear me talking, but the problem is the throttle is very touchy. I barely touch it and it launches to full throttle. I tried lubricating several parts of the cable and linkages. It seemed to help a little. Is there anything else I can do to smooth it out?? I am basically...
Finally had a chance to take the machine AKA "Dual Red" out. It has been super, super wet here in pacific northwest and finally had a dry day to try it. It exceeded my expectations. Having no mulching and just a flat deck, means the material just gets shredded, I heard no bogging down of the...
