ETX TECHNICAL TIPS
Sent: Friday, June 22, 2001 5:12:31 From: firstname.lastname@example.org (David Birmingham) Dr. Sherrod thought I should send along my modifications to his ETX-125EC pier, found under Telescope Tech Tips, (ETX-125EC Pier (2/7/01). After I sent him a photo I took of the almost completed project. Basically I followed his design, except I could not find the industrial shelf brackets so I decided to use 1 1/2” angle iron for the legs. I purchased 3 pieces of 36” marked of the 19” leg length he mentioned. That left 17” for the pier support. I then cut 45-degree notches and bent the legs to 90 degrees and welded the cutout (note, some flattening will need to be done to the flat side). The leg braces are made from 1” angle with the appropriate angle cuts to fit the legs and welded into place. The leg spacers are made from 1” angle and are also welded for rigidity. To the eyebolt leveler legs I added cap nuts to create a dome shape to the end of the bolt. The nuts for the leveler legs were brazed into place on the legs. I then wrapped the leveler leg threads with Teflon plumber’s tape to make them turn smoothly. Not having a set of scales I do not know what the weight of the pier is as it sits in the picture, but it is heavy. The weight was what prompted Dr. Sherrod to encourage me to write in with my modifications. He thinks there is enough weight and stability in this pier to support an LX200 12”. To weld all of this metal together I used my Lincoln Hobby Welder with 2-mm flux coated electrodes. As with most welding, some grinding will be required to make smooth joints, but this assembly will definitely not fall apart. Thanks, Dave
Subject: Pier Done! Sent: Saturday, June 23, 2001 11:33:29 From: email@example.com (David Birmingham) It's been raining off and on for the better part of the week, so garage time was available. The attached photos show the pier as completed. Maybe the paint needs a little more dry time. Counting the primer there are four coats of paint applied. I was going to do the clear overcoat, but when it dried I wasn't happy so I applied another coat of the matte black. My goal is to make the ETX-125EC stand out and not the pier. I have checked the turn buckles and they are as tight as I can make them without any major material failure. Like I said, now all I have to do is wait for the UPC driver to bring me a SuperCharged 125EC. I hope your trip goes well. By the way, I will certainly leave feed back on Mike's page about your service. I think readers should also know how courteous and helpful your are. I hope that doesn't get you swamped with e-mails. Mike, you already know, but I wanted to let you know what a GREAT colleague you have, and keep up the wonderful work. I thought I would pass along my willingness to help with the site, like typing, sweeping, or anything I could do to help Weasner's Mighty ETX Site! Sincerely, Dave
