Ice Scratcher Idea

I can see it working very well on the trails but when you get to the deep dark forrest (brush) they will grab onto every twig you go over.
 
Great looking idea, I am a believer in keeping it simple. If your sled was on a stand and you put a straight edge along the bottom of your carbide, would the bolt head be above or below the bottom of the carbide?

Do you feel its widening the carbide track or cutting its own even deeper. I have been playing with ski scratcher ideas for over a year now, the challenge I run into most os all the different skis out there. It seems that having reverse has changed the rear profile of many OEM skis while aftermarkets like Simmons and SLP keep a fairly flat profile.

You mentioned in your earlier post that any longer or shorter didn't work so good. What ski was that based on?

Just to be clear, is the nut welded to the bottom plate still threaded, or did you drill it smooth bore so the bolt actuall has some travel? Do the 2 nuts stacked on the bottom act as stiffeners, or do they jam somehow and are just loose for the photo.

I will be giving this a try. My Dragon 163" melts hyfax in less than 100 yards if I don't have the ski scratchers down. "Necessity is the Mother of Invention", I guess you might be the Father. lol. Great post, thanks. EW
Eric, My skis are all different, I believe the ones in the pic are Poo sidehillers ?,but I use dooly carbides on everything because they don't dart on icy trails. The scratcher marks always show up deeper than the carbide marks. I think a little tailoring for each would be helpful. I looked at a beautiful new set of Simmons skis yesterday and I thought round top and bottom plates might work best. Once you get them set they are ride and forget and if you do knock them off and you have some drilled bolts and clips in your pocket you are back in business in minutes.Thanks Wolf
 
I would only assume that when they break off on a rock or log or what ever that you pick up the piece and throw it in your sled to take home. Just bustin' on ya. In all fairness, have tried a set-up like yours and the problem I had was when they did break, it was useless for the balance of the day. Have you tried the Slidekicks Reverse Compatible Scratchers yet?

Whitefish, I would like to see a set of the Slidekicks work, I have seen them on the forum but new tech is slow coming out here in the sticks. Most winters lately it is high 30s daytime an freezes hard at night so since the advent of paddle tracks scratchers are a necessity. My problem with the original spring scratchers was if you broke one in the morning you WERE done for the day. We tried the little springs on the ski bolts too, less than a month .I always broke the same side too. In fact I took a bunch of left side springs to the dump not long ago. Thanks Wolf
 
Looks like a good design to me, I will be making a set for my sled soon. I don't see any issues with them hanging up on brush and even if you were worried about it you could take them off in a minute. I was going to go buy a set of scratchers but this is a much better idea and much cheaper.
 
Was it the E or F that was tough on the knuckles? I ran one for quite a bit....lovely!

Opus, The old 8Ts and early Es were hard on the body alright , I have the hands to prove it. I remember a lever bouncing off the end of my finger. It still brings tears to my eyes, Thanks, Wolf
 
Good work Wolfrun! I built a set and installed them on my d8 with snowpros. Gave them an honest test today. Ran up a packed road til my engine temp read 151,stopped and put your design scrapers on,then proceeded up the road. The engine temp steadily dropped til it was running a stable 124
I was impressed! The location I mounted mine takes a little more effort to turn. I believe mounting a little further forward would ease the steering effort. Again thanks!
 
They are only a soft 5/16 bolt and they bend or break in the snap pin hole. I have knocked a few off, even on my trailer ramp while loading off the ground and never have felt anything at all. I went over the bars once, dropping into a tree hole at 35 mph or so. I don't EVER take any chances on going over the bars again.

do you think your scratchers would work on single carbides skis?
 
M7Bandit. Yes I think they will do fine. You may have to set them a little deeper for singles But maybe only 1/2 inch deeper. My fishing partner runs his a little deeper on his Simmons wide carbide skis. He cuts the heads off the bolts as he thinks it looks better . It still does the job but the carriage bolt heads throw up a lot more snow dust. The trails are frozen solid in the mornings now and absolutely no hifax or heating problems.
 
Hey guys,
I am not trying to be negative but that bolt hanging on your ski's looks like it would cause alot of drag on your sled and mess up your steering. have you had any problem with that or noticed any drag? I also think if you are going through hyfax then your sled is not setup right and you have to much pressure on the front of your skid. I rode my 2001 800 skidoo for 7 years and never wore through the hyfax, yes they did have wear on them, but they still worked fine. this will be my first year on a Polaris, so maybe I will need some ice scratchers, but I have never used them before.
 
I'm thinking drilling the hole on the inside edge of the ski right in line with the spindle might be the way to go. Less effect on the steering and more in line with the track....
