John E Fry 16 Report post Posted April 1, 2016 Hi all, I'm trying to compile a comprehensive list of Steadicam centre posts. Just for interests sake really, but could be useful for those trying to upgrade, repair or replace their posts, gimbals or upper/lower boxes. Here's the rough list I have so far - but what's wrong, incomplete or missing? Share this post Link to post Share on other sites
Janice Arthur 171 Report post Posted April 1, 2016 John; Very nice, thanks for doing this. If you could add a column for arm post diameters that would be helpful too. Many times people miss that detail because they're are now so many. A la carte parts and generations mean the arms don't often match the gimbals. Thanks, Janice Share this post Link to post Share on other sites
John E Fry 16 Report post Posted April 1, 2016 Hi Janice, Actually there's already a column for that - Post dia. x sections. Diameters of those I have first, followed by number of sections. I'm missing a few though - know what diameter the Archers & Clippers are? I'll break that column into two for the final version. Any details not quite right?

Alec Jarnagin SOC 177 Report post Posted April 1, 2016 John, I'm sorry, but this is very confusing. I believe you're trying to list the center post size AND the diameter of the arm post that fits into the gimbal, yes? If so, there are some mistakes. The 3/3a is a 1.5" center post and the gimbal requires an arm post with a diameter of 5/8". The Master series and all Ultra sleds are 1.58" center post using a gimbal that takes a 3/4" arm post. The 3/3a standard was why GPI PRO also used a 1.5" center post and the gimbal requires an arm post with a diameter of 5/8". XCS was the first manufacturer to switch to a 2" center post but they kept the original 5/8" arm post size for their gimbal yoke. Share this post Link to post Share on other sites
Janice Arthur 171 Report post Posted April 1, 2016 John; Yes make two columns and what alec said. I missed the distinction. Janice Share this post Link to post Share on other sites
John E Fry 16 Report post Posted April 1, 2016 Ah, fantastic! Thank you, that's the sort of response I was hoping for. Some of the models I can find no info on anywhere so put in whatever 'post' measurements I came across until I was corrected - some of these being the gimbal arm post sizes, not centre post, as you point out. I hoped by putting these in as so obviously wrong it would spur people to correct me, et voila! I could even add an arm post column if you think that might be useful?

Janice Arthur 171 Report post Posted April 1, 2016 John Yes an arm post column makes sense to me, that's the column I wanted. The rig center post not sure what they are indetail but if you looked at monitor arm diameters that would give you lots of info!!! Share this post Link to post Share on other sites
Frank Schwaiger 0 Report post Posted October 13, 2017 Hi all, sorry to dig this out again but I can't find the proper figures of the new M1 post diameter. Is it 2"? And if so why are so many complaining? Cheers! Share this post Link to post Share on other sites
Jerry Holway 143 Report post Posted October 13, 2017 M1's gimbal post is 1.75. Some of the 1.5" posts are specified at a slightly smaller diameter. There are manufacturer's tolerances to consider, too. Share this post Link to post Share on other sites
