Fin set up Question

edited April 22 in Skis Fins Bindings
I’m wondering about specific adjustments that will help me to make my offside rff (1,3,5) turn more crisp? Using the CG fin. I’m currently at:
30 1/8 front boot
6.873 length
.818 dft
2.493 left side of fin block with a washer mid hole
2.490 right side
The difference in depth is odd to me, it seems that the left side should be shallower than the right since I have the washer in there. My 2,4 is crisp. I’d like to get my 1,3,5 to come around harder.
I tried going deeper but going deeper wasn’t the answer.
Thanks in advance!

    @Steven_Haines if you are running the CG fin I would say @adamhcaldwell and @AdamCord should be tagged here. Some other folks may have advice but as the creative team they probably have the best information and advice.

    @Chef23, I would agree, just hoping for any help. If I can get my off to match my on, I’m off to the races.
    You skiing yet? Been cold here in Colorado!

    @Steven_Haines what is or isn't happening that you wish to change on your offside?

    Something is off there with the washer - When installed mine was visibly shallower on that side of the ski. And its measuring counter to what you'd like for fixing your turn so I'd figure that out first.

    @Jordan, I’m wanting it to complete harder at the completion of the turn. Less school bussish. Probably more me than anything.
  • Steven_HainesSteven_Haines Posts: 995 ★★★Triple Panda Award Recipient ★★★
    @BraceMaker, I know that inherently the sides are going to measure differently but without the washer, there must really be a difference! I’ll have to take it out and remeasure. I can see the gap between the ski and fin clamp.

    I measured without the washer and there’s a 12 thou difference. R side of the fin box is shallower

    @Steven_Haines Remove the washer and tighten down the fin block, then then measure and set your fin, then re-insert the washer. That ensures that your fin block won't flex in the opposite direction from the pressure of the washer.

    Edit: This wasn't a suggestion to improve your offside turn, but who knows? :smile: Also - Skijay (I think) posted a video about torquing down the fin before inserting a washer. Showed the fin box bowing instead of the ski.

    Not sure what ski riding? Or if you're double boot guy or rear kicker. Hopefully your front boot measurement is not too much forward from stock. That can hold it back from rotating around. I would move your front boot to stock setting. Get your depth offset as close to each other as possible. Asymmetrical holes will take care of the rest. That seems like an awful lot of length for the amount of depth you're running for a CG fin. I would take out at least .050 of length out. We've had a lot of success with less than 6.800 length & around 2.500- 2.520 depth. That was on the c-65 Denali . c-75 shorter yet , shallower & further forward. Or you could do like what's been suggested by the Adams , whatever the stock settings are for your ski adjust everything at least.020 shallower, deaper& forward.

    @bf` I just re did it and got the same thing.

    @Skierx, the ski is a 68. Front boot is supposed to be 30 1/4
    When I set up the CG I set it up where it was and pushed it forward.030. I love the fin!
    I’m Hardshell with HRT kicker.
    Currently the depth on both sides is really close.
    I could try less length. I tried moving the bindings back 1/8 when I added depth. The combination was a flop!

    The Cg fin shouldn't need a washer at all. The latest ski i have tried the Cg fin on was turning like a school bus. 67 Helix with Double Radar bindings, I was about 1/8" forward of stock recommendations. Pulled binding back to 29.75 and it came alive.

    @Steven_Haines start by trying forward and shorter with the fin by moving .010” each and see if that seems like it is a good direction. If so keep going until the tip feels like it’s too high, then you’ll know you’ve gone too far.

    @Steven_Haines several comments:

    1. Remove the washer. The CG fin has a similar effect to the washer on a normal fin, only better.
    2. Do what Adamcord suggested and see how that works
    3. Your settings sound a little off. If Cord's suggestions don't pan out, I'm on a 68" also and have tried a number of settings, but have come back to:
    30 5/8
    6.845
    2.490
    0.72
    6.5 deg

    Don't be afraid to make big moves with this fin - it has a much bigger sweet spot than a normal fin.

    Thanks Guys, one question though, with the washer I end up almost even depth wise on either side. Leave it in or out? No disrespect Bruce, I guess this question is directed to Adam cord
  • AdamCordAdamCord Posts: 672 Open or 55K Rated Skier
    @Steven_Haines it’s not abnormal to see a difference in depth from one side to the other, especially when you consider that by turning the caliper around you are measuring in a different spot on the ski. That being said you definitely don’t want too much reverse offset like that, so I’d suggest keeping the washer.

    Thanks @AdamCord, looking forward to trying it!

    @Steven_Haines - I would consider taking a straight edge and measure the flatness of the ski at the fin block on each side to determine a potential root cause for your issue. You might also want to measure the fin block for flatness / symmetry. Also, is the fin perpendicular to the ski?
  • Steven_HainesSteven_Haines Posts: 995 ★★★Triple Panda Award Recipient ★★★
    @DW, good thoughts! I’ll check it out. I wish that I could get out there now to try the new adjustments but heading to California in the am thru Monday 👎👎👎👎👎👎

    @Steven_Haines 68" ski. But what brand, model and year?

    @VONMAN I know that you’re going to laugh but I Love this ski. I have had newer ones and the next best one was a D3 Quest. I just jumped back on an old Radar MPD. I have 5 sets on it again and my better half says that I look more comfortable on it and she feels me less behind the boat. I really want a C75 but I bought a trailer instead so that I can spend the summer on the water. Hopefully I’ll be on the C75 before too long.

    New skis don’t always help. My alpha was far too drunk to run the -35 it promised me this evening. Damn thing barely got around 2 ball at -28

    @aupatking I agree! Sometimes certain things work. Not comparing myself to Scott Larson but he has love for the X5. My MPD just feels like home

    @Bruce_Butterfield, just wanted to say thanks for the set up suggestions. I tried multiple things and then tried your settings within a few thou and Boom, the ski came to life! Thanks again!

    Larson's been on that x5 since high school....82 Nats Illinois?

    @liquid d, I’m not sure what he’s riding now but since I met him in 2005 he’s been off and an X5. I think that he now owns all of the 66” X5’s ever produced 😁
