Is there an alternative to the 61809 SKF gimbal bearing? Surely there must be a cheaper alternative. Is there a particular reason this bearing is being used? I understand this is a thin section bearing to fit in a narrow space but wouldn't a slightly larger pan case allow for a cheaper bearing? I am new to this so if I am missing something please let me know.

Sure, you could modify the measurements of the pan case and it's threaded ring as well as the yoke to accommodate a different bearing. But of all the places to skimp on a stabilizer rig, the gimbal is the wrong piece to try and cut corners. Once you build it for a certain bearing - you are stuck with that bearing.

Yes I am talking about the pan bearing. I appreciate the heads up but McMaster-Carr is a big site. Do you have a part number or direct link to the alternative bearing?

Hey Neil, no I did not forget to put it up. I forgot to run it back by Cody first. I don't want to violate his copyright. So I'll wait to get the ok from Cody and it will be right back up. I remember I only paid $28.05 plus S&H.

It's not a copyright violation to post the item number for an alternate bearing, Cedric. Go ahead and post!

Hey Brett, with all respect do, I see it in the same manner as you would see the DIY Guide for the Mini35. Cody's book is his to decide who would have access to certain information. Just as RedRock Micro separates the difference between their public and private forums, due to the fact that someone has actually purchased the DIY Guide directly through the company, maybe Cody would want to do something similar to that, i.e. protect his copyright.
By me giving out privileged info of that nature would be like me giving out part numbers to the DIY Guide from RedRock Micro. If Cody says it is ok then I will post it. Besides I made the mistake of sharing info with someone who did not want to share info with other members of the forum. They left the forum after they had gotten the info they needed. So I feel that if they haven't put in the time of searching through the forum for things they need, I don't feel as though I have an obligation to do it for them. Put in the time and effort and if them can't find what you need then if you ask some of the members may point them in the right direction.

Cedric, I too scratched my head when you initially replied about running it by Cody. I couldn't understand why it would matter to Cody if someone found a cheaper alternative to a part with the same specifications. But your real objection is with sharing ANY information from the privately purchased book, in this forum. I can respect that. Taken to the extreme, if every part, dimension, and assembly was discussed in a public forum, eventually someone could piece together the entire book from the forum and book sales would stop. I simply never thought of it that way. It is up to Cody to decide if the owners of the book can, by it's very nature, publicly discuss the technical details. I doubt he will have a problem with part substitution, but that is his decision to make. Neil p.s. OK. Where is Cody?  (just kidding) |

It looks as though Neil has a copy as well. You could PM him the number.
In this case you are giving out the number for a bearing. Cody gets nothing for it.
Also, if you look in these (the Cody) forums, we have often given out alternative part numbers when we find them.

I would have done this earlier but I have been tied up with my van for the past month and a half. I just put 1500 bucks in it and it still doesn't start. But any way here is the info you needed:

Is this bearing good enough for the pan bearing? I see it's an Abec1.... I would have assumed ABEC3,5,or 7 would be better
