Hello fellow Instruct-ables... What better way to celebrate space than to look at it through a really big telescope? I have been an ATM for quite a while and this is my latest project, a big refracting telescope on a big mount.
Step 1: Gathering Parts
The mount is made from mostly easy to find scrap parts I found on line. I spent a lot of time looking for scrap pieces that were close to sizes I needed until I found that the metal merchants would cut pieces to size for pretty cheap. I used common power tools such as a small drill press, router, circular saw and chop saw. Working with aluminum is a lot like working with very hard woods, the cutting feels the same but slower.
The chassis is made of 1/2" sheet aluminum. The bearings are pillow block bearings. The Main(RA) shaft is 2-5/8" diameter aluminum and the smaller(dec) shaft is 1-1/6" steel. The large worm gear was purchased cheaply from an astronomy website.
