In Search of a Bobsled

Just curious why a bobsled instead of a go devil, maybe like the one Tristan (Dobbin Forestry) had some pictures of a while ago. I have been goofing around with different styles of go devils and have had a lot of failed attempts. The best design I have come up with is more like a stone boat. A bunch of 4′ 4″x4″ held together with a couple of rods that I put the butt of the log on. I can tell a huge difference in how hard the team is working when I am using it. The down side is it only takes one decent sized log at a time. I have been trying to decide between making a bigger go devil and building a bobsled with a bunch of old irons I have laying around. The idea of a bigger one being taking more then one log at a time.

…. think the bobsled would be better suited to the job. The added maneuverability of the bob would also be a plus.

It isn’t about skidding logs with horses, it’s about working horses in the woods. This requires the right tool for the right job, an arsenal of equipment with varying application.

And to answer Tom, the go-devil usually doesn’t have a pole, and we are talking about several hundred bf of logs over long distances.

…..

He asked if I prefer full or half moccasin runners. He suggested half moccasins as he felt they held better on side hills. Can anyone explain the difference between the two and a suggestion about which they prefer?

I have always had full moccasin runners……?????

Instead of having a hook on the roll to which I attach my evener, I think I would prefer a ring that I can hook onto with a grab/swivel that I use for ground skidding. That way I can unhook from the sled and go to ground skidding without having to attach a grab/swivel. Any thoughts on this modification and its advantages/disadvantages?

Carl, you mentioned some changes that Les Barden was making to the top bunk that would facilitate easier chaining. Could those modifications be incorporated into a traditional bobsled?

I believe that the way that I chain logs on my sled is by far the most effective manner. I only mentioned Les’ ideas because in the design he is considering they may work….

How about carrying your gear on a bobsled? One of the things I miss about my logging arch when using the scoot is that my arch has a place for all my gear (saw, chains, peavey, tools, places to hang chaps extra coat etc.). When using the arch, all of this stuff is easily accessible and doesn’t have to be moved to when skidding logs. Not so with the scoot. I have devised someways for stowing gear, but there is still a lot of shifting stuff around. Any innovative suggestions to tackle this problem with a bob?

I leave my clevis and swivel on the evener and just slip the evener over the hook on the roll. The hook should be on a steel strap that wraps around the roll and comes back under the pole, otherwise on a hard pull the horses will turn the roll, and break the pole right off….

Also, bridle chains should be attached to the roll…

Stake pocket on the end of the bunk hold it together, and provide an additional place to attach hooks, chains, etc.

A steel strap shaped to hold the peavey. I use an old trace bolted to the bunk t hold my chain-binder. A pin, or in my case a u-bolt or staple to secure a central hitch-point for load chains.

I find ways to carry all my tools by hanging them on the peavey. I made a small plywood box with a fitted lid years ago, that would fit saw, tools etc, and chained it to the sled, but I found I didn’t like leaving my tools in the woods. I find ways to carry the tools back out with me on top of the logs.

Back to the question of moc or 1/2 moc runners – In my experience, a straight sided runner (non moc) cuts in to the snow much more where as the moccasin runner floats thruough the snow like a boat in the water. 1/2 moc runners would I assume have 1 side straight (vertical) and therefore float but also dig in – useful on a side hill. My cross chain 2 bob moc sled is terrible on a side hill, diving down hill once it starts to slip at all where my straight sided runner sled cut through more but does fine on a side hill. Jay

Man these pics bring back some memories. This was about 15 years ago….

…….Carl, 10 years working exclusively with oxen, that is something. I would be interested in reading about what you see as the advantages and disadvantages of oxen and horses working in the woods. Regarding the bobsled, thanks for posting those pictures. Can I take it you have full moccasin runners when you write “I have always had full moccasin runners……?????” I tried finding your method of chaining logs on a bob and came up short. Can you direct me to that thread or article? Is that a u-bolt that extends through your top bunk for chaining logs? Do you use the “weavers bind” (see attachment)? This sled-maker suggests 6×6 yellow birch runners tapered down for the moccasin runners. Any thoughts on that? Finally, I notice you have an indentation on your rave irons in back of the bunk for a skid. I have seen a sled with indentations on both sides of the bunk. Any advantage to that?

As far as oxen vs. horses, the only tasks I didn’t do with my oxen were mowing hay (they were too slow) and spreading manure with a spreader ( they couldn’t hold it back very well on my hills….they didn’t take to the britchen too well). Other than that, the only difference I found was in their behavior….. oxen are so even tempered. There are other differences, advantages both ways with hardware and application, but I’ll expound on that in other places….

I do have full moccasin runners now, and always have. I just put ????? because I ahven’t experience with 1/2 mocs, but I have the same experience as Jay with straight runners. My bobsled runners are 6×5″ cut down to 3″ shoes. Double steel….. one that fits the sled, a second tacked on to take the wear…..

The article is attached to this thread….http://www.draftanimalpower.com/showthread.php?1232-Moving-Heavy-Loads-With-Horses/page4
I do use what your article refers to as the weavers bind, but I think I describe it and diagram it better……:cool:Bobsledding Logs.pdf

6×6 runners are probably a little bigger than necessary, but certainly won’t break…. I have had 4×6 runners with 3″ shoes and they stood up well….

I do have a U-bolt that goes all the way through my top bunk….. remnant from a swing-bunk design that I don’t employ, but it helps to give me a solid central hitch point. For years I just used a 3/4 bolt or pin and started the left side chain on the right side of the pin, and vice versa.

The indentation on my sled is in front of the bunk, Brad Teeter made one with it behind the bunk. I prefer it in front because when the log is on the bunk the natural incline will be above the skid where it rests in the divot. If the skid is in the divot behind the bunk, then the log can have pressure on the skid, making it difficult to remove, especially if you skid is as large as your bunk so that you don’t have to roll your logs up an inch onto the top plate at the last minute. I use a skid pole that is the same diameter or slightly larger than the thickness of my top plate, then the logs actually roll down off of the skid onto the sled, and yet when loaded they shoot upward toward the horses, and over shoot the skid so that I can remove it….

And here is a link to a short clip of using the bobsled last summer in red spruce….

Sorry for once again leading the thread way off its original topic. The more I think about it the more I think I’ll move the bobsled rebuild up the list in front of the scoot. The comment about wearing out the team dragging the scoot back up the hill was a great point that I had not really thought of. My steers are still young and dragging trees for more then a couple hours wipes them right out. I would hate to waist their efforts on an empty scoot. Although so far I have kept the skids short enough the go devil does the trick. Thanks for the great info guys!
