Want to post this for our Wisconsin members.
First annual show for our club.
If you like old cars maybe you like old sleds.
Show is this Saturday in Oshkosh.
Bummer, I fly to Appleton tomorrow to do some splineology training at Speed Queen in Ripon. Staying in Oshkosh but I fly home Friday night. My first sled was a Motoski which I bet will be well represented at this show.
Have fun!
Change your return flight to Saturday. 
Splineology? Not familiar with that.
Motoski, that goes back a ways.
I liked their commercials, where they drive down a creek bed over rocks to show how tough they’re built.
Splineology is the term we use in the spline world to describe the math functions and general parameters associated with splines. If you desire there is a part of a book that I wrote on our webpage. Go to westmichiganspline.com click the technical button and then theory. Pretty boring for most but is a window into how those teeth get put on all of the shafts in our cars.
Motoski’s were like tanks and could run on anything, didn’t need snow. Quite tippy though.
I’ve owned about 50 different snowmobiles over the years. My dad had a 68 Evinrude Skeeter and my brothers and I shared a 70 Moto Ski Capri. The fall of 1973 at 8 yrs old I saved up my money from feeding calves on the farm and bought my own sled. A 1974 Sno Jet (Strato jet) I paid $400 for it brand new. My favorite older sled was a 1974 chaparral sst. Chaparral and Bobby Unser and family used to do their R&D testing on the Unser ranch in New Mexico. I always thought that was cool.
They cut splines at Speed queen.
Didn’t know they had a machine shop there.
We currently use a shop in Illinois for our spline work.
May be contacting you for a quote.
My first sled was a 67 Evinrude Skeeter, 16hp, a tank. Had a lot of fun on that sled.
Sno Jets were cool.
Love the Chaparrals. I believe they had the first IFS sled.
Speed Queen and most washing machine manufacturers use splines in the gear box of the washing machine and for the agitator. Our process does not cut them they are rolled in a cold forming process. Go to you tube and search West Michigan Spline and you will be able to watch some being rolled.
Turn up the heater, I’m sitting in MSP on my layover. Looks cold out there.
Checked your website.
Now I see, you build the machines, I thought you did the spline work.
It was above zero when I left for work this morning, actually felt warm when I walked outside.

Yes, Chaparral was ahead of the times on technology. They had a prototype already for production for 1975 with independent front suspension, outboard rear shocks and Kelsey-Hayes hydraulic discs brakes. They were racing with that design in 73. Unfortunately, they used Salsbury clutch on the 74 sleds and they were all failing within a few miles. Chaparral was a standup company and they replaced them all on warranty. With all the profit and money used up. The parent company closed the door on production. Artic cat applied the technology to make the first production sled with IFS on the 79 Trail cat.
my 74 ssx had two gas tanks. Chapparral develop it in racing so they could use the fuel to bias the weight for better handling. On the production sled one tank was larger then the other with a switching valve. You could run on the smaller tank until you ran out of fuel. Then switch to the larger tank and know you had enough fuel to get back home and not get stranded out in the woods. Pretty cool stuff 
We do make the machines as our bread and butter and as a service we do production runs as well. Would be glad to look at whatever you have. My email is on the web page.
A few pics from the show.
It was a bit cold out there.
The Mercury, Moto Ski and Polaris Rat sled won their divisions.
The Mercury was nice, someone put a lot of work in to it.
Love those pic’s! Another blast from the past. Thanks for posting. To bad my timing was off.
I’m only 10 minutes from Appleton. I own 3 old Scorpions and have a large Scorpion Snowmobile Dealership Sign Collection. One sled is apart and 2 are very nice. 71’ Stinger and a 72’ Stingeroo. I love the red metal flake wedge sleds since I rode them when young. I could not make the show but remember seeing that sign for it somewhere the last couple weeks. I’d like to buy that Polaris TX (if it’s cherry and a 340) as a gift for an old friend if you know who owns it.
The one in the Moto Ski pic?
Don’t know the owner, but could ask around the club see if anyone knows.
Club President knew who owns it. But he doesn’t believe it is for sale.
Owned by a guy from Egg Harbor.
If you want his name I can PM it to you.
Here is a better picture of it. It is a 340
That’s the one. Yes, please forward me his name and number if you can obtain it. Things change hands over time and at least maybe I could be first on the list.
I miss racing through Michigan snow in the Polaris 440.
