I'm building an ice buggy, and trying to figure out the best plan. I have some awesome 24" straight blades from reel mowers to cut up to use for the blades, and access to a fully equipped fab shop. I also have lots of crusty ice with no snow on it, so this project comes at a convenient time

There isn't much documentation of ice buggy designs.
ewilhelm of instructables built a crab design after it sounds like he experienced many OBEs with a trike style. Perhaps the blades were too grabby?
To look at it though, his original trike buggy kind of sucked, with no seat to speak of, narrow wheelbase and short blades with excessive curvature. And his crab rides pretty stable and edges nicely, and is small and fits well into a car.

Then I've seen videos where standard buggies are converted to ride on ice with no apparent issues, and of course ice yachts are effectively tricycle style as well with front blade steering.

I know ice buggying is fairly uncommon, so looking for info from someone else who has blades on their buggy? I'm leaning towards a classic trike buggy style right now, just looks more versatile and less likely to flip on less than perfect ice.

I built an ice boat.

The crossbar is two boards laminated together, glued with weights holding them down whith blocks under the ends to give them a curvature. The runners are large angle irons I got at Home depot, but I intend to get better quality metal from one of a couple metal stores on the internet. I use the hub and bearings from a wheel I found at Harbor Freight for the steering. I built the seat myself.

Thanks Saul, your boat looks a lot like what I have in mind. I'm going to use a piece of 1" iron pipe for the initial crossbar with the runners pivoting on the ends so they can ride over chop easier.

I'm planning a shorter "wheelbase" with direct steering like a buggy, to get a tighter turning radius on smaller lakes and an easier build.
Is there a particular reason your boat is so long? Does it help with stability at speed?
