Which tool to use ?!

Hi guys ! I'm often unable to check if my mortises wall are straight because all my squares are too big to fit it in the hole, even my smallest 4" square. Am I missing something or is there a tool made for that ? I most often use my chisel blade but it doesn't tell me if my mortise is perpendicular to the surface...

Use a guide to keep the walls vertical .....

When you chisel the walls, use a square guide to keep the walls vertical like this:

The answer to your question will only be as detailed and specific as the question is detailed and specific. Good questions also include a sketch or a photo that illustrates your issue. (:< D)

Woodnthings suggestion is good. Another option is to make yourself another long square from stable hardwoods and cut off an end to fit into your mortise. I struggled with your delima until I started cutting my mortises with routers... They hold the bit at 90* and a 1/4 or 3/8 bit are exactly the size you choose. My MT joints are now always very near too perfection. I assemble them by hand (no mallet etc. needed) and take them apart by hand, yet the hold when I pick them during dry fit. I can elaborate further if you have any questions.

Its' never hot or cold in New Hampshire... its' always seasonal.
