ramp kits

Ok I live in Southern Lanc county. I tore down an old small barn with a buddy and kept the lumber....it was true rough sawn 1" x 14" bds. Not in the best shape, but good enough I could use them for some stuff.....SO...I decided to cut them down to 7' long and 10" wide put OSB in-between for more strength and screw them together to make a set of ramps.......Long story short>>>they are 2 3/4 inches thick and I want the ramp end kits for them....I can only find them to fit 2 by lumber...ANY IDEAS?????

OH YEAH>>>>Forgot to mention...stupid me after cutting them realized they were 200 yr old red oak...glad I saved the rest...make a great cook space beside the stove and some awesome end tables!

Can't you just take off 3/8" from the top and bottom at the end and make it like a tennon and slide the ramp kit on it? a slight lip is not going to hurt it.

Exactly...just dado it so the top edge makes a smooth transition.

Sweet wood!

that is what I have thought about doing......but me being 6'4" and 275 lbs i want the ends as strong as possible...thats why I made them the way I did
