You can look at the gaps between in the blade and the table insert and see that it's getting smaller and bigger as the main table moves.

Ok, that's what I thought. That degree of movement is not normal I don't think we've ever seen a main table have this amount of back and forth movement with or without all the locks engaged!

So for diagnosis purposes, it would be helpful to get more videos.

I'd like to see a video at carriage level looking up at the main table (remove the blade guard so just the blade is visible relative to the table insert slot) while applying the same kind of force to the main table. Maybe resting camera on carriage?

Install your aux table (the one with legs) on the right side of the Shopsmith with camera at main table height and repeat video. Then set the aux table with camera on it as low as you can and repeat video.

Are you moving the table left and right OR are you rotating the table back and forth.

I just went to the shop and loosened a front and a rear trunnion bolt and am able to create movement very similar to that in your video.

Have you done a main table to blade alignment. If so, how close to parallel (blade to miter slot) is your table? Mine measures about .004".

With the trunnion bolts loose, that number more than doubles.

Alternatively, with the table rotated 90 degrees visibility of the relevant parts is improved.

If I am not mistaken, you are in the Phoenix, AZ area. Maybe you could make direct contact with some one in the Phoenix area. I know there is at least one forum member there.

If I had to resolve this apparent instability, I would begin my convincing myself that the headstock and carriage do not move (with respect to one another and then work upward from the carriage (table legs, trunnions, table bolts, table).

keonep, More pictures would be nice but I would follow along with dusty's suggestion and work your way up from the bottom looking for something loose. There could be more than one unstable connection in there also. I also saw one of my esteemed colleagues pointing out above that the entire base may be loose, a state I recently received a machine in where the way and bench tubes were not locked down and it would sway side to side.

Ok guys sorry for the delay I was out of town. Here's where I'm at so far. I don't know if I need to replace the post or if the piece the post goes into is bad.

The pin should go all the way in (nearly flush on both ends)
.I strongly recommend NEW Tappered pins and verify that you are putting them in from the correct side of the post (see manual).

Hi, I verified they were placed correctly but I can go ahead and order some new ones.

The tapered pin isn't on the parts list and isn't on the parts diagram which is odd. Anyone know the part number?

Sorry, I thought the part number was in the Double Tilt manual I linked earlier. You might have to call Customer Service for that order. Was the pin seated before? That seems loose to me, even for no pin. I think I have a tie bar with no posts, if I can put my hands on it I will compare it to your video.
