ok guy what have you used on your boats and how far apart are they. start at transom and how close to bow did you install them.
thickness/ width how did you bond /screw them in any help would be great

mine are going to be 3/4 x 3/4 oak going to square ends at transom and angle cut fronts 3m 5200 and stainless screws into each rib
just not sure how far apart or how close to bow they should be
 
Hey john my icerunners are about 15 inches apart they are made of ipe and fastened with 5200 and stainless then epoxied im in toms river also and would be happy to help if u ever need it

I also used IPE. Mine are trapizoid shaped, 1 1/2" at the hull, 1" at the ice. I through bolted and screwed with SS, bedded in thickened epoxy. I then installed hard plastic rub rail with SS screws and 5200. Mine run from the transom to about 2 ft from the bow. I would suggest you run them all the way to the bow. Try to envision where the water line/ ice line may be when you are fully loaded... I took some damage to mine because the runners end at that line. How far apart? I could measure, but what is important is that they are the lowest point on the hull of coarse. Mine are likely about 2ft apart. Really depends on the hull profile. I have a displacement hull, so they are likely closer than I might put them on a planing hull.

1" with 3/4" aluminum over the top. SS screws, epoxy in the screw holes, caulk instead of 5200 to bed them down as I want to be able to remove them easily if one ever gets damaged.

Mine were done this way from the builder and it made it super easy to repair and replace them after I broke one this past season. Mine were about a rib too short towards the bow as my boat was built to be on display in a restaurant and the cradle it sat in interfered with the standard length ice runners. I found they didn't do much good in the ice at slow speeds because they were too short. I broke one on my trailer last season so when I replaced them recently I went to the next rib.

They used to end behind my forward trailer support, which was too short.
 
ok getting ready to install runners
im having a hard time picking what to bed them with

5200 and stainless screws or thickend epoxy and stainless screws
 
John~

I always bed the wooden "runners" in 3M 5200 - then screw the metal on dry.

I have never owned a wooden Sneakbox - so do not know the common practice. But, at least on Great South Bay Scooters, the wooden "runners" are better fastened NOT into the frames - because they can weaken the frames - but BETWEEN the frames with machine screws, washers and nuts. This photo shows where I plugged the original hole in the frames with a dowel and later fastened right through the planking. The 5200 distributes the loads along the length of the hull. And, I later ground the machine screws flush with the nuts.

All the best,

Here is the process I used.......
Dry Fit

Wood flour and epoxy mix,Strapped and weighted down

Small fillet

screwed and glued with 5200, notice leading edges bent upward and trailing edges ground flat


5+ seasons and a lot of ice with no issues

well they are on
I put them on with 3m 5200 black hope they hold I have them all strapped down and screwed in with 2 in ss screws.
and let me say this it was the biggest PITA will never do that again .if I could do it over ( and hope I don't) id use thickend epoxy instead
it was a major messy and going to need lots of sanding scraping
