Re: How to downsize a rock too big for my saw?
If you go talk to your local tool rental shop they might like to help you out. They have huge saws to cut concrete. Other saws cut brick and even tile. The cut is strait but not as smooth as a lapidary saw. You have to make a vice to hold the gneiss firm so the was wont just grab it and pull it into the saw body and bend the blade. Make up a box for a mold and put the gneiss into the mold centering the rock so the saw will cut were you want it. Fill the mold with cement or concrete, let harden and remove from mold. Cement is easyer to chip off and put the rock in a plastic wrap to act as a mold reliece. Now this nice block you made is easyer to hold and cut with a construction grade saw. You should tell them about the block idea as soon as you can to ease their mind, the cost of these saws is very high. Another good idea is to bring them a plate of homemade cookies, nothing beats home made. Bring some ather material with you to show them what you are doing. This gives a hands on guy a better idea of how to help you out. They might charge you for doing this or the cookies might be a welcomed tip.
