Sorry for the newb question

I'm doing a madRose bridge and the grain is wild as you can see...

This is quite different from the nicely quartered wide grained Indian RW I used before...

The wood feels solid and stiff, (but on the heavy side)

Thanks!

Alex buddy MadRose would make an excellent bridge.  I can't tell from the photos of yours if there is anything specific to your pieces that might not be acceptable for a bridge.

one nasty thing is that it is oily, or at least that is what i believe judging from the severely clogged sandpaper.

Doing a mock fish-glue-up between spruce and the blank offcuts.

Other than that, with a bit of 360 grit and shellac it looks nothing short of stunning.  Not-making-justice-pic:

The chocolate lighter brown Maddy is usually much lighter in weight than EIR. The dark purple-ish red Maddy is a bit heavier than EIR. Either make excellent bridges.

Ditto that. I would be leery of it due to the high oil content and taking a risk with good adhesion.

The only two bridge wood I use are BRW and Mad Rose, I have always found that it makes great bridges adhesion with either fish glue or HHG never a problem.

Here's a recent one on my last guitar.

I use it all the time and never had a problem with adhesion. It is perjaps my favorite bridge material besides BRW of course.

I love it as well. Never had any adhesion problems. Because I don't use BRW, it's my favorite bridge material.

I admit i chickened out after the first mad-bridge I made split while doing the simple task of inserting the saddle. I barely levered it while checking the cut is ok... it would not have survived a single string up to pitch. My luck is that I made the front narrower than usual, otherwise i would have glued it and got the split while stringing....

On the second, pictured, I made the front on the wide side (7mm at base, 5 at the theoretical breaking point) and it feels ok.

LV fish Glue test went nicely:

surface prep: scraped with a razor
clamp time: less than 1 hour
pressure: very low

With the recommended 12h clamping and normal pressure it shoudl hold quite nicely.

Notice how the spruce gave up between grain, but the dark lines ripped some small RW particles.

I use it allot!!!!
I have more than I'll ever need!
it's oily alright-but I've never had a problem with that!
make sure your glue joint is perfect-on the top of the guitar as well as the bridge!!!

I have found that wiping with acetone or even denatured alcohol before sanding or gluing make the task a little easier on oily woods. Sandpaper clogs less.
