Been loving this series! Please continue it with finishing the inside and stuff as well! I feel like that is always missing from these builds on RU-vid
I have an identical concrete pier arrangement. Just FYI - due to the underlying ground swelling and shrinking due to water content, the concrete pier may tilt very slightly at times. To be safe, I do a very quick polar alignment using my ASIair Pro prior to each observing session. It is almost never off by more than an arc minute or two, but I always try for 20 seconds or less in polar alignment error to improve my guiding. Your pier may be less susceptible to ground movement than mine. Good luck.
I've got the same tube for my build, can you tell me how many bags I need to get to fill the tube?. I like the way you put in the all thread, good idea!
Nice job on the build. FYI, If you vibrated the concrete during the pour it would’ve minimized the air pockets but using it indoors should never be a problem.
Hi! Awesome to talk to someone from Australia. I was originally going to use concrete anchors to thread the rod into but instead tested one in a hole drilled about a 1mm smaller than the rod, then grinded a small bit of the thread off the rod and hammers it into the concrete, it trie to pull it too with all my strengths lol and it wasn’t budging so I did all for rods the same way and they weren’t going anywhere. Thanks and clear skies mate from the top side of the world lol!
@@AstroPilotchannel Thanks mate much appreciated. Every other pier build, they dig a hole and cement into the ground however I already have a ready-made room that I'm going to convert. Has a cement floor, your solution is exactly what I need. Thanks again. 👊
Actually used an electric sander to vibrate the outside of the tube, also the rebar is anchored 3 inches into the concrete, iv only re polar aligned mabye 4 times since the build, very happy with it
For your underground network/power conduit, stuff both ends with steel wool. This will keep Mice from crawling into the conduit and causing havoc. Typically they get to the first elbow, get stuck, and croak. This is not a good thing. We had this happen in a 2" PVC conduit required by building code to vent a gas line to a kitchen island.
I’d say so, can’t go wrong with concrete, it’s way cheaper than any steel pier that you can buy, iv heard some bad things about possible vibrations in steel piers too.
@@AstroPilotchannel Well, in professional hosting facilities they use steel piers. Only 1-2 counterweights of my system are heavier than entire your system. No vibration is seen at FL>4000mm. But these piers are more expensive; you’re right.
