Grind or not to grind?

[QuickMick]

Does everyone grind the front ribs on a SQ when doing a reinforcement?? I didnt grind them, but its not too late.
2010 resalution, "not to do anymore glass work" haha

As an engineer I always disagreed with grinding out the stiffeners. You wouldn't remove the floor joists in your house and add an extra sheet of plywood because you'd fall through... The concepts are exactly the same, only the application is different.

Good call on the word change. I made the change in my post as well.

this is fiberglass not wood and the application is completely different. I understand what you are saying but it's not correct in this situation. Those ribs provide some support, but it's nothing compared to the fiberglass reinforcement that is added. If what you say is correct, then there would be no benefit to grinding and reinforcing at all and our skis would actually be less rigid w/ removing ribs and reinforcing... and we all know that is not true. Another thing is air pockets around the rib... that will make your reinforcement a waste of time anyway..

GRIND EM!!!! :smokin:

Not sure if your saying there are air pockets in my glass work or in general. Because there are none in my glasswork that I see.

I would remove floor joists if I was replacing it with a concrete slab.

I was thinking about it in a similiar fashion.....if you are actually going to add that same amount of material back on, but over the whole area...then grind em. I guess it really depends on how much material you will be using.

In a SN, don't waste your time grinding out the top deck ribs... just hit them from the side with a hammer. It is a lot quicker and they fold right over.

no, I was saying generally speaking, if you leave the ribs it makes it very difficult to lay the cloth w/o air pockets and air pockets will make the reinforcement useless...

Not to mention the fitment of the B pipe afterwards. You'll have to grind a bunch down.

I ground mine out when I reinforced and have had no structural problems at all(RN and SN), and i beat my skis hard. Ask anyone who knows me.. also anyone that knows me will not let me ride their ski either...lol.

 

[Waternut]

How much material are you guys putting back when reinforcing?

 

[WILKEY]

one layer of 17 oz. on the sides for me. then the nose gets like 5 hahah

 

[kevbo]

Those ribs are for pole bracket support. End you reinforcement at the ribs, nothing is gained by removing them. Its best to add material to each side of the ribs if more strength is desired.

 

[WILKEY]

GRIND THEM. dude the pole area on the sn are so weak to begin with.

 

[ryan]

2 layers of 17 for me.
