Making your own strakes

Post by Murry » Mon Dec 15, 2008 11:36 am

I'm considering making my own strakes out of epoxy like Shine made for his fs17 low sheer.

I would be using a piece of angle one inch by one inch for the mold.

Questions:

1. What epoxy filler blend would be reccomended for this?

2. Would it be best to taper the triangle flat towards the bow or design the mold to keep the triangular shape as it tapers to the bow ending with a dull point?


Thanks for any input,
Daniel

milled fiber & Cabosil mix well to peanut butter consistency.

as far as shape I would keep the edge to a point but I have no reason to justify it.. :doh:
... you thought epoxy was strong!

I am pretty sure that Shine specifies what he used in his FS17 Low Sheer build thread in the Power Boats section.

Murry,

I recently make a couple runners/strakes using Joel's method.

I also used a 1"x1" angle coated with some PVA. Used about 18 fl. oz of epoxy per strake.
1. What epoxy filler blend would be reccomended for this?
I used milled fibers and chopped glass. The consistency was somewhere between ketchup and peanut butter. More like thick shampoo. Maybe about 4 tablespoons(?) of chopped glass. I tried to get the mix as thick as I could while still thin enough to flow out flat in the mold.
2. Would it be best to taper the triangle flat towards the bow or design the mold to keep the triangular shape as it tapers to the bow ending with a dull point?
Not sure I can visualize what you are thinking here. My strakes are 7'4", so they will only go about midway. I was going to try to glue them on as straight as I can.

Murry, I plan on tapering mine so the water doesn't his a flat surface even if it is only 1x1x1.5. I believe Joel tapered his also. Joel used milled fibers, chopped glass and cabosil in his mix. You can find it in his build.
