how much elevation and length you got to play with?
I'd love a machine to dig with. Imagine how much you'll be getting done with a big bucket on the digger

I dont think so. The heavy equipment is just there to move dirt quickly and do some really rough shaping. And if you totally blow a line and have to redo it, remember that you are doing this in the fall and that come springtime NO ONE will be able to tell where you screwed up the line- the forest is real quick to take things back fall-spring because of the leaves and then rapid growth in the spring. You can also stockpile good dirt, or rocks with the machine for handbuilding later on.
Also remember that everything settles and shrinks, especially over winter so build those berms big! it easy to shave them down later on, but a real PITA to have to throw more dirt on them by hand and slap compact with shovels. And only assholes have said "gosh, that berm was just too big. I prefer smaller, less supportive berms".
Lastly, I think that an underutilized trail feature on slower, tech trails with berms is little side hips into berms, and then the ability to kind of pump the berm and jump out of them onto a roller. Slower speed pumping, popping kind of lines. YMMV.
Good Luck! Sounds like its gonna be sick!

I haven't even scouted the lines yet. Not a hell of a lot of vert, but enough to put a few in.
My biggest concern is drainage. With our lack of vert, we tend to use as much as possible and flip it back uphill to go back down again. Back a while ago I saw a nice article on slope geometry when building berms. I cannot find it now.

And yeah, I always ride the lines as we build. I run them first, rake, ride, then make more changes. I build with a guy who does not do that and it kinda drives me nuts, but he's so chill and works so damn hard that I don't really care. Plus he always says just go back and make it better. Zero ego.

Yeah, was thinking like a french drain at the low point.

Being able to import or easily move rock, and bring in drain pipe should go a long way into addressing drainage issues. Dealing with that shit when you're hauling stuff in by hand is a lot harder.

We went back in and removed some drainage from a trail to make the berms work better and it seems to be fine. But we don't get much rain and the ground in that specific spot drains quickly. Plus it's not a huge deal if there's a little water or mud down in the inside. We did put in one actual drain pipe but I wonder if that's just going to wind up getting clogged up after a few years.

Yeah, I find the entrance to the pipes needs to get cleaned out every few years. A big diameter (6 or 8"), non corrugated pipe helps. And stacking rock and gravel around the entrance to try to keep the sludge at bay helps too. And shaping the area so the water runs quickly and doesn't just build into a mucky puddle that slowly trickles through the pipe. But they still need occasional clean outs, regardless.

Assorted Kinda random machine tips.
Get out and look. Things look way different from the machine than ground level. You can get tricked into thinking the machine is sitting level and build off of that, when actually it's sitting at a slight angle. Hop out, visually 'ride' the line, get downhill and get your head level with the trail.
Build it first, drain it later. If you have pipes, dig a sump hole at the mouth and dig down so there is a collection basin to collect silt. If you are not using pipes, the crux move is tapering the berm so it drains out the bottom but still provides support. It's easy to build up the berm too much at the top of the turn, think about providing support against the natural fall line of the trail. If you can drive the machine around the corner smoothly you prob got it right. It's good to put in a grade reversal before and after corners to keep water out of your corner.
Use the angle of repose. Everyone want to build super sick, super steep, instagram berms, but those fall apart and get that overhanging wave feature after a while. Get the radius right, you can literally take a section of rope and mark a radius, and let the berm choose its own steepness based on angle of repose of the materials available. It's may look kinda flat but it's gonna be durable.
Roll a fatty.. a fatbike is a huge help for getting a feel for a section while it's still off soft and rough from the machine. Also great for compaction after some moisture to a finished trail.
Don't be afraid to say that sucks and go back up and redo it. trail sucks!

the dirt in my local woods is perfect and 12" below is pure sand. we can have a monsoon and it ready to ride straight away how we've designed the drainage.
I dig a sump in side some of the berms to collect water for sculpting the lips and berms

Well, I guess this belongs here, though it's pretty WTF for a tool video.
ride bikes, climb, ski, travel, cook, work to fund former, repeat.

I laughed.
Seems neat, probably not for heavy use but yeah I'd love to try that out for occasional work farther away from a road.Last edited by jamal; 10-31-2020 at 10:03 PM.

It’s a kickstarter project

Carrying the whole “system” in your pack is a bit of a stretch. Savings comes from interchangeable, collapsible handles.
Good luck to ‘em

spent some hours on a new trail but been grave digging so no real chance of a photo in the dark. Berm today though a left hander in to the 1st little table, to a right hand shark fin to left hand catch berm on to a drop(where my pals skinning up) to a right hand berm spitting you on to table, left right berms to a step up.
probably about 40 man hours to get this section done. It flow well and feels funky

Nice work!
I've been out a couple nights this week cleaning out drains before a couple storms move in this weekend. It's about time, we've only had noticeable rain once or twice here since March and not enough to be able to do any digging.

you can have some of our rain, whats your dirt like with so little rain?
