Has anyone else found that, at times, when they put their stock into their rotary, the live center does not fit with the stock’s length? My rotary is aligned with my 60" X-axis. Per the assembly instructions, the linear rails are 1" from the tailstock end of the rotary frame. When I loaded a 24-1/…

I’m distracted by the glued up plywood, the incised line and number- what’s it going to be?

File this as a ‘hack’ rather than a solution to your problem: Use more than one live center. It will almost certainly have a different length, so the gap will no longer exist. It’s a 2MT taper. Actually, the whole tailstock is a bit of a disappointment compared to the rest of the overall rotary kit…

I reported this well over a year ago I then did the “hack” and just used 2 different live centers. I was then having problems with inconstant parts. I did find out that with the center extend it just was not stable. So I bought a 2nd center. Now I never extend the center that is holding the par…

Yikes! That’s scary. So if I’m understanding this correctly the problem you found was the combination of the live center and extended quill barrel gave you unacceptable deviation. Is that right? Do both of your tailstocks behave in the same unacceptable way? It makes me wonder if the point of the …

I never noticed that before. I just went and measured mine and the usable stroke of the tail stock is only 2", but the stop spacing is 2.38". That is definitely a design error. The spacing needs to be less than the travel to guarantee it will always reach.

Let me add this question to the mix: Has anyone tried - and been successful - with re-greasing the rolling bearings underneath the live center plate? I tried with a normal grease gun (essentially identical to the one Avid supplied) but the grease gun’s tip just cannot quite get underneath the plate…

I know that this is an older thread, but you can get a longer tip for the grease gun. I just got one from Amazon that is 1.5 inches long, and replaced the .5 inch long tip that comes with the grease gun with it. It works like a charm.

[New Tailstock Assembly] After working around this for a year I decided to make a permanent solution. Restating the problem, pin spacing is 60mm and the quill can travel 45mm. So there is a dead zone where the tailstock won’t reach. My solution was to redesign the plate with two sets of locking s…

Very nice solution! Where did you find the pins, McMaster, or did you just buy them from AVID? Also looks like you made a nicer knob for adjusting the tailstock. Did you make that on the AVID as well?
