Telescope Making

By Paul N. Hasluck

"Work" Handbook Series

(A Quality1905 Reprint)

Since WWII, building your own telescope meant buying large glass discs and abrasives, then waltzing around a barrel to grind the discs into a mirror. Once mounted into a tube, the mirror became a reflecting, or rather, a Newtonian telescope. The type covered in this book is different.  You will find the in-depth manufacture of the 3-1/2" Portable Telescope with an Altazimuth Mounting. 

Here you learn to build a large astronomical refracting telescope with a 3-1/2" objective and a body tube four to five feet long. If you put an erecting eyepiece on it, you can use the scope for terrestrial viewing.  You might want to build the small finding 'scope that sits on top with it's 12" or so, long tube.

Contents include:  materials for telescope making, making the mounting, making the clasp and clamp, vertical and horizontal slow motions, telescope body, lenses for the telescope, object end, eyepieces, finder and steadying rods, finishing and lacquering;  erecting and adjusting the telescope.

This, of course, won't perform like a Newtonian telescope if you're truly interested in astronomy. What it could do is make a great project if you have a lathe and build it from brass tubes with all the accessories. Lathe or not, you might even be able to adapt the principles to build a scope using some of the huge surplus copy machine lenses advertised in liquidator's catalogs.
