Hey all! New to the forums! I have been around tools my whole entire life, my brother and I built a skateboard half pipe at the age of 14 by ourselves, so needless to say I sort of know my way around the garage.. lol I am taking up a project building an American Girl dollhouse and I am stuck… I bought 3/4 MDF and I need straight rips true to size to make them stack.. Every time I rip a cut it is always off, I have built a jig and measure for displacement and tried that way I just cant seem to land a perfectly cut straight line.. I would love any and all tips and tricks to guide me along the way! Cant wait to meet you all and continue my journey into woodworking!

it sounds like you are trying to make your cuts with a circular saw? If so, get a piece of quarter inch or eighth inch plywood that is wider than the base of your saw. Attach a straight 3/4” board to one side of this plywood as a fence/guide for the base of your saw. With the left side of your saw base against the side of the 3/4” board as a guide. make a long straight cut thru the plywood piece. Now you can clamp that to the mdf, with the edge of the cut plywood along the line you want to cut. As long as you keep your saw butted up to your fence, you will make a straight cut. It is useful for accurate cuts on larger pieces when you don’t have a panel saw.

Good advice from Mike P., but are you sure you want to use MDF? It’s awfully heavy, and produces very toxic saw dust. I also think 3/4” is way to thick for the walls of a doll house. I would think that 3/8” thickness would probably be more appropriated.

The answer here is difficult, because we do not know what tools you have available.

Clamping a straight board to your work and running the sole-plate of your saw against it should give you the control you need.

Use the same board with a router and trim your rough cuts straight.

-- nice recovery, They should pay extra for that mistake, Eric E.
