I have a stanely 12-904 and questions.

What angle should the blade be sharpened to 30 or 25 degrees?

What is the main use for this plane?

I am having trouble getting this plane to work any help appreciated!

Is this a smoothing or jack plane?

since it's a smoother bench plane I'd sharpen it with a 25° bevel angle....

providing the frog angle is 45°

Agree...

Make sure your chip breaker lays flat across the back to the iron and is adjusted back from the edge 1/32"-1/16".

Do you mean put the chip breaker away from the taper of the 25 degree angle to the iron full thickness and back further by 1/32 - 1/1/6"?  Maybe a picture would help?

Once tuned up, this tool felt similar to the vintage Baileys I’ve used for years. After I replaced the stock blade with a 1/8-in.-thick Lie-Nielsen blade and chipbreaker, this plane produced a consistently thin shaving in dense hardwood.

 

Is the blade and chip breaker that comes with the plane defecient?

I will have to re sharpen to 25 deg tonight as I mistakenly did 30 deg.

Red arrows (best I could draw them) indicate the distance from the edge of the iron to the edge of the chip-breaker. Blue arrow shows where the chip breaker should lay flat across the back of the iron.

Assuming so, but just to verify, you do have the bevel down as shown?

 

As for resharpening from 30o to 25o, I would just resharpen the leading edge and leave as a micro bevel. Eventually you will have it fully back to the 25o. Saves time if you're doing it by hand. If you have a Worksharp or some other powered grinder, I guess you could fully regrind the angle but I would go with the micro-bevel. My $.02

Thanks for the information.  Now I see the micro edge is a great idea! Thanks and I had the chip breaker up to high.  Thanks again.

Also I had the bevel up not down because how else would it find wood to lift up.  But I see (lightbulb) this is a smoothing plan to when it finds a ridge it will shear it off.

Thanks a million.

Glad it was helpful. Let us know how it works once you get it tuned up.

I got it tuned up or at least producing shavings but was wondering should the blade be coplaner with the bottom of the shoe or do you stick it a little further down?

 

I guess it goes to a turorial on the user of the plane does anyone have one or directions?

I guess it depends on grain type and wood species as well as end, edge, or face grain and what you are actually trying to accomplish.

 

Paul Sellers tutorial blog and his You-tube videos gives some of the best advice IMO.

QS WO rough milled.

Face and edge  and grain no.  I save that for the small plane.

May not be the best plane for rough sawn to finish thickness especially face without some camber in the iron. I assume you've tried going either cross grain or at angle for your first passes.

To answer your previous question, you'll want the blade (iron) edge protruding some. How much is some? What you are comfortable with, no tear-out, able to move plane without undue force (rub some paraffin wax on the sole to reduce friction), yet able to get a consistent curl. Watch some of Paul Sellers videos...
