Smoothing Lego Bottoms?

The only smooth bottom Lego pieces I am familiar with would be the boat bottoms:

Thanks for the info. Unfortunately, those are rounded and they may be too thick. I was looking for something that had the thickness of the "thin" or flat pieces, but that fitted in a reverse fashion.

Take Care.

Try putting technic 1/2 pins into the bottom of the blocks and using a standard smooth plate.

only things i can think of are #1 cuttin the green baseplates into yout shapes and possibly paintin them

or using the megablocks gender changer piece 2x2 studs on both sides with tiles (where to get a bunch of these is beyond me

this piece:

may help you out, but i dont see how it will solve your dilemma. there are other modified bricks (check that site under that heading) that could help.

perhaps a double studded plate (studs on the bottom and top of the plate) could be used, and then a smooth tile could be placed over the bottom studs.

That would probably do the trick. Since I have plenty of smooth plates, if I could get a hold of a few double studded plates of regular height, I can attach smooth plates to the tops and bottoms.

I'll check lego's site and bricklink.

Thanks for the info.
