Indy 500, bad idea. I still have that switchback/RMK you wanted for sale.

NICE WORK!!!!

FYI.. That 45 degree Chamfer (or extruded portion) adds a fair amount of strength. IF you just drilled the holes, the boards would flex more.. with the addition of the formed metal, this not only hardens the metal some, but the extruded portion adds strength as well!!

Probably wouldn't hurt to use a air ratchet, or 1/4" impact to speed up the process...
Again.. Nice work.. when I saw the pics.. I thought you installed newer Cat boards on that Polaris..

You want mail. go to profile. Indy 500, your switchy was my practice sled. 24 holes per side. Did 2 sleds this weekend. You need to do this young man. I am having many dies made. this is a great idea. I did 24 holes in an hr. total of 96 holes in the switchy. p.s. this sled started 2nd pull. NOT for sale! pauly, no air ratchet. Holes will not be uniformed. I used a torque wrench and I have the mystery torque spec. that works. spent 3 days on perfecting this whole thing. Not as earlier posted. contact me if you are interested.

<font color="ff0000">I have made and done the same thing, great idea.
I have also been roped into doing other peoples sleds now. I threaded the inside of my die 1/2-20 UNF and milled 3/4" 6 pt. on the top side. As if welding the nut to the die. Boards look factory !</font>

Oh thats right you are pre Edge chassis. The switch is getting a second round of more holes yet. They look cool and actually add strength.

getsome, we tried the threaded die. It did not work as well since we are torqueing each hole to be consistant. much easiler to torque from the top side. Also bolt spins against bottom of running boards and die needs to be held steady when threaded. Also what do you do if the grade 8 bolt binds in the die. Real hard to remove from running board. I have done massive amounts of testing and what I offer works very well so far. Our dies are made out of hardened steel and tough enough to drill thru let along tap threads into. Are we riding Halfway to Chaplau this yr.?

I'd like to see some pics with more holes than I put in, would like to put in more, concerned about strength. I have a previous post with pics up above, curious to see what others are doing. I have another sled to do, may want to try a different pattern.

polarisrider, looks great tho! i found an 05 600 switchy 45 minutes away from me with 1200 miles. but bent handlebars and cracked console so i figured rolled over? but everything under the hood was 100%. o yea, did i mention it was $2500?

getsome, that is the same pattern that I did on an IQ chassis today. Note, you can add 1 more hole to the inner row closest to the front. The spot is not dimpled but you can drill it anyways. Takes you 1 hole closer to the front. Take a pic. of the back holes that you do on the double thickness area for me.
