RogerTheDodger Posted June 5, 2012 Share Posted June 5, 2012 I wanted a pier so I could set up quickly, and to have something more sturdy than my HEQ5 tripod legs, so here is my brick pier.Standard brickwork on a concrete paving slab - this will enable me to easily remove it when we eventually move house. I took the top from the tripod legs and secured it to a 10mm thick round ally plate that sits on four short adjustment bolts. to secure the mount on top I took a standard 10mm bolt and re-profiled it with an angle grinder to I can use the original tightening knob from the tripod to secure it for easy adjustment. 3 Link to comment Share on other sites More sharing options...
pete_l Posted June 5, 2012 Share Posted June 5, 2012 Neat job! It's always nice to see alternatives to the ordinary steel pillars. I hope the brick corners don't cause any scrapes or bruises in the dark. Link to comment Share on other sites More sharing options...
RogerTheDodger Posted June 5, 2012 Author Share Posted June 5, 2012 The ally disk stops the scope hitting the bricks, I'll eventually setup limits in EQmod to stop that, but I've fallen over the tripod legs more than once so this must be an improvement Link to comment Share on other sites More sharing options...

RogerTheDodger Posted June 5, 2012 Author Share Posted June 5, 2012 Thanks, the Mrs wanted something that looked nice so I'll be building a sundial to go on top when I'm not using it. 2 Link to comment Share on other sites More sharing options...
Baffa Posted June 7, 2012 Share Posted June 7, 2012 Why did I never think of this? I have some leftover bricks and I was about to throw them away! Looks like I got a summer project Thanks for this idea Link to comment Share on other sites More sharing options...
juliosky Posted June 7, 2012 Share Posted June 7, 2012 Wow thats a great idea looks more natural in the garden (bird table when not in use).How about engineering bricks and putting re-bar in the holes? Link to comment Share on other sites More sharing options...
Chris Posted June 7, 2012 Share Posted June 7, 2012 Great idea, I predict a fair few brick piers popping up after seeing this Link to comment Share on other sites More sharing options...
Gina Posted June 7, 2012 Share Posted June 7, 2012 OK, so what's the matter with this? A brick column like this is pretty strong. I know when making a concrete pier it is recommended that all the concrete is poured in one go without letting the first lot go off first. With wetting, mortar sticks well to bricks. Houses and other buildings have been built this way for donkeys years - why shouldn't we build a pier this way? I don't know - is there a reason? Or is it really that nobody has thought of doing this before. Apart from sharp corners, I can't see any problem! (Anyway, I like my round concrete pier - so there! ) Link to comment Share on other sites More sharing options...
RogerTheDodger Posted June 8, 2012 Author Share Posted June 8, 2012 That's what I thought Gina, a pier actually only needs to be able to carry the weight and not to flex. Link to comment Share on other sites More sharing options...
Tinker1947 Posted June 8, 2012 Share Posted June 8, 2012 That's what I thought Gina, a pier actually only needs to be able to carry the weight and not to flex.Your right, but i showed the wife the brick pier and all she said was " When you building one" so being a nice looking pier does go a long way toward harmony.....

JamesF Posted June 8, 2012 Share Posted June 8, 2012 I read something a while back written by someone who had built a brick pier, then decided it didn't work and took it down to replace it with (I think) a steel tube. I can't recall what the reasons were, but obviously it doesn't mean brick piers don't work, just that his brick pier didn't work for him.James Link to comment Share on other sites More sharing options...
RogerTheDodger Posted June 8, 2012 Author Share Posted June 8, 2012 Curious to know his reasons. I like mine, it was easy to build (no digging) and is solid as a rock - if you give it a thump it barely vibrates and seems to dampen off immediately. The only detractor is that it's in the way if you want to image at the zenith with my 8" newt - but I've only done that once.As I said in the OP, the main reason was for speed of setup, I just drop the top on an spin on 4 nuts, add the cables and away I go... PA is good enough for the guided sub lengths I'm doing now without having to re-do it every time I set up. Link to comment Share on other sites More sharing options...
JamesF Posted June 8, 2012 Share Posted June 8, 2012 I had a moment of enlightenment and discovered the passage in "Setting up a Small Observatory" by David Arditti. He says:I previously tried making the telescope pier out of brick. This pier worked, but it was bulky and not so strong as the much narrower concrete and steel pier which replaced it. Laying bricks is time-consuming and needs to be done quite precisely, and brick structures are in fact surprisingly elastic, but with little impact shear strength. Overall, I do not recommend a brick pier, though it looks quite nice.The picture of his shows it to be two bricks long on each side however and there's no indication of what filled the internal void, so his opinion of his won't necessarily apply to yours.James Link to comment Share on other sites More sharing options...

RogerTheDodger Posted June 8, 2012 Author Share Posted June 8, 2012 Ah yes that is way bigger. Mine is about 31" high which is approximately the same height I sat the tripod up to (it's lowest level), I don't think I would have gone much higher in a single column, I probably would have made it wider up to about half way.

JamesF Posted June 8, 2012 Share Posted June 8, 2012 Page 82, the gate is hung the wrong way, the Brace is bracing nothing... So what are we saying? Don't let him build your pier *or* hang the door on your obsy? James Link to comment Share on other sites More sharing options...
Gina Posted June 8, 2012 Share Posted June 8, 2012 I've read David Arditti's book and disagree with a number of his ideas. As for hanging the door the wrong way or building it wrongly... well... I rest my case Link to comment Share on other sites More sharing options...

Tinker1947 Posted June 9, 2012 Share Posted June 9, 2012 Thanks for the comments, now getting the thread back on track, there must be curved bricks on sale someplace, or it can't be that hard to make some moulds and make them out of cement with a colourer added...????
