Anchoring My Head

Speaking of wood fillers, for the purposes of overdrilling holes then inserting scews, etc. is wood flour as good as say cabosil?

When I built my dinghies I used wood flour to make filet's prior to fiberglassing a corner. Of course when making a natural wood finished dinghy the wood flour was perfect for blending.

Thanks

Matt-

My guess is that the wood fibers cut directly into by the stainless steel screws where water could enter them would rot and the matrix would be weaker right there at the boundary, but whether this would substantially weaken the screw's overall grip would be questionable. How far would the water get into the matrix? How small are the wood cells/particles?

Probably would be necessary to take a lab test carried out over a period of time for the fungus to do it's work to see if there's any difference.

It would be interesting to compare the strength of the screw holding with different fillers and the wood before and after exposure to water over time.

Guessing as always!

Good point about the wood and water. Wood flour is very fine like a powder. I know the filet's held up like steel but I wonder about the impact of screwing into it as you point out.

I happen to have wood flour in the shed but it makes sense to get fine cabosil just to be sure of the strength and water reactions.

Thankyou. Your explantion was much clearer and more accurate. You are correct , the filler gives it different characteristics.

I know, I know I've spent more time discussing this project than it should have taken me to complete it. But one more question.

I found a good source for those threaded inserts www.mcfeelys.com I was going to try some of these inserts without epoxy first. I have multiple thread type choices and was hoping someone could tell what type of wood C-Dory probably used for core material below my marine head. That way I can make the best thread choice.

Thanks
