EZ DEC THREAD
This steel thread insert kit is intended for use with Meade 7" through 12" LX200R and LX200GPS telescopes. If your Dec thread has not already stripped but you wish to prevent future failure, do not buy this kit. Instead, buy the EZ Clutch Kit
On these telescopes, Meade's declination lock design utilizes a locking knob with a small diameter 10-24 threaded stud. This stud threads approximately 1/4" deep into the scope's aluminum trunnion. The use of steel screws into aluminum threads is problematical as it causes rapid wear of the aluminum thread, and is usually limited to situations where there is a one-time use. Because of the high force required to effectively clamp the declination lock, the life of the original aluminum thread in a regularly used telescope can be as short as 2 years before the steel stud has worn down and eventually stripped out the small aluminum threads.
Thread wear, and the need for this kit, have been anticipated since the introduction of the GPS scopes. The failures are no longer hypothetical - they have been occurring. This kit installs a steel 10-24 thread insert into the aluminum trunnion, extending thread life indefinitely.
If you have installed the EZ Clutch kit, declination clamping forces have been significantly reduced and wear on this critical aluminum thread will be minimal. And if you installed the EZ Clutch kit within the first year of scope operation your existing aluminum thread should last a lifetime. You should not need this thread upgrade kit.
Because of the significant variation in trunnion configuration found in the LX200GPS scopes the best way for us to assist you is to address each thread failure individually. As a consequence, this kit is not offered through distributors, and must be purchased direct.
You've never tapped a threaded hole in your life? Not a problem. Our high quality very detailed step by step photo illustrated instructions walk you through the installation as if you had a machinist standing at your shoulder coaching you the whole while.
Tools you will need: a 3/8" electric drill, a standard tip screwdriver with a 1/4" to 3/8" wide tip, and either a Vise-Grip® type pliers or a small adjustable wrench. That's all.
