First, do you want to grind the mirror yourself or buy one already made? If you want to grind the mirror yourself, you need the mirror blank and griding supplies. You may use a grinding machine to "hog out" the mirror but the processes is time and labor intensive and requires a suitable working area. It's far easier to just buy the mirror already made. Generally, what you will need is a primary mirror, mirror cell, secondary mirror, spider vein, optical tube, focuser, nots, bolts, and screws, and a mount, which you can build if you want. Go to There are many resources there for amateur telescope makers. You can do this various ways, but the designs are generally the same because a newtonian is a particular design of telescope.

First you have to get two lenses (should be similar in size), then have two pieces of cardboard pipes or PVC, where you can move one closer or farther depending on the distance of the object. Google has a lot of ideas and you can visit for ideas too. Newtonian scopes are the easiest.
