SEB NEO Coaxial Unit Help Needed

Hi All,
Sorry for being late in response. This problem is probably why the rest has been sitting. If you get a short strap wrench, you will be able to realign the shafts without further damage. Tape might help if the strap wrench spins and doesn’t grab the shaft. There isn’t much clearance between the body and post, it will not take much of a bur to bind the rest body up. The gears might be binding up on the shaft, because of the miss alignment. If you try moving the body much you many just cause further damage. All parts can be made if you have something that can not be saved because it has to much damage.

The first thing I would do is to realign the post. If you have a long enough thin steel ruler, lay it across both posts at the base of the gap between teeth. That will give you a better idea of how both posts sit. Then you can use the strap wrench to twist the post until the ruler sit flat across the gap at the bottom between two gear teeth. I would be hesitant too use a file, you might nick things up.

If you are not comfortable fixing it, I will work with you on fixing it. It might be a little while before I can get to it. Unless I look at it and it 30 minute fix.

Let me know if you have more questions.

The first picture shows how high I could raise the coax carriage before i cleaned up the posts and filed away some burrs. Second picture shows how high the coax carriage will travel before becoming stuck. I also loosened the set screws on either side that tension the pinion shaft. Third photo shows how far the left post is turned in. Fourth photo shows how far the right side post is turned in. I also checked with a feeler gauge the clearance on each side of the carriage when it is lowered to its lowest position at the base. Both sides are even. Another forum user suggested I heat the base up around each post to loosen the press fit in order to rotate the posts back to parallel. I'll wait until I hear from you on how to proceed. Thank you for reaching out. JH
It looks like that the initial setting of the rack gear posts have been changed or for I don't know why it's re-aligned improperly? That is strange only about the last one inch on the top the teeth are damaged?
In my shop I can fix it all and re-polish the rest easily and quickly and it would be like new again, however it will be a long way and expensive due to the overseas shipping and our 31 % import local duty/tax for all things. I am sorry that it is not a good choice!
In this case I would recommend you to contact Ernie to have it repaired by Dan Ekstorm our competent service guy who lives close to Ernie in WY. It will be a permanent and the best fix.

‘even if the repair is free it looks to me that if the threads are the problem that is NOT a warranty item and being the reasonable fellow that you are that a amount will be paid to fix said rest

just sayin

the kindness expressed by the maker and USA seller is great but from where I sit the forum is not a place and,should not be a place to get free non-warranty items

and just for the record not implying the op is anything but above board, merely making a relevant comment to the discussion at hand

and only because my comment on what may be the problem certainly has merit

hope you all can interpret the comment as helpful not hurtful
guess we shall see

I'm not looking for any freebies. SEB offered to look at some pictures and his recommendation to me would be to contact Ernie and their machinist Dan to get an idea of what a repair would look like. There are a number of problems with the posts and Ernie ensure me that Dan will be able to get things back to original condition.
 
OP never asked to recieve anything for free ?

That is exactly what this forum is for. I’ve also contacted Seb on this forum.
 
re-read my post with someone who speaks English and you will see I never said the op was anything but above board

did not want others to think

I AM CLUMSEY AND DROP,THE REST EVERY DAY AND THEN I GET FREE WARRANTY

also if it were me I would probably replace the 2 vertical posts, don’t like the threads even after they would be cleaned up, they just don’t look good to me,
‘and I never would have bought the rest after seeing that, but hey that is just me, hope it works out for the OP, he has handled the repairs well so far
 
well it has been a month

how about an update, it would be interesting to know what was or was not replaced in order to bring the unit back up to new or newish

Ernie and Dan were very helpful. Dan replaced both posts, drilled and counterbored holes in the base in order to secure the new posts in place, and disassembled, cleaned, and adjusted the coaxial unit. Rest is now working as it should.
 
great news
thought the posts should be removed

amazing what can be done to get it back working

bet you are going to really enjoy it and they probably tuned it up a bit so the joystick works as it should

now go out and enjoy it, congrads
