I bought a used 510 last week. It has proably never seen oiling or wax.

Today i got to the point of installing the table. loosen the tightner and the table would hardly tilt.

Then waxed it up and put the tubes and one table on about six inches from main table... Yup, moved down quite easily... So, like has been said do not wax the wedge.................. Like has been said, put the legs on but, for some reason humans like to be lazy and it takes to much time. (about thirty seconds).......... Maybe glue some sandpaper to the wedge to give it more grip????????????

If your trunnion was tight, quite possibly you should do a table alignment using the $20 bill trick. Basically, you loosen the trunnion bolts, place a $20 between the rear trunnion and tie bar and then do the alignment. Remove the $20 after tightening the bolts. The $20 acts as a shim giving the proper gap while the table is aligned. There's a Sawdust Session which shows this and it is also covered by several threads on the Forum. I'm too lazy to search for it right now.

Thisshould reduce the need for a great search. I tore my dollar bill in half today.

That's why you should have used a $20. You'd have been more careful!:D

Thanks for posting this Dusty. I was about to because I noticed yesterday that my 520 table is tilting left without extension tables but with the heavy fence used on the right side. I have checked about 4 times in the last 2 days and each time have noticed a tilt. I have not waxed the table tilt hold down areas.

Does anyone have reference to the proper maintenance that prevents this? My SS is around 25 years old and the 520 upgrade was 2 years ago.

I would expect vibration could induce this, but I now have a PP and no vibration.

It looks as though we are in this pickle together. I have not completely resolved my issue either.

To be able to work safely, I am using an extension table in conjunction with the main.

dusty wrote:I found the diagrams on a different page but you are absolutely correct. Shopsmith recommends the use of either telescopic legs of the extension table in all of those optional set ups.

I do believe, however, that my table tilts with less force than it used to.

I have a brother who is a great deal heavier than I am. One day while I was teaching to use the drill press. He placed his elbow on the table. I litterally watched it move under his weight. The telescopic legs are the answer. Jim

Since no one has a good idea why this is happening (sorry Jim, I don't have an overweight relative - just me) and Nick doesn't provide a clue in the SS video, I am taking it all apart this weekend . I think that I will roughen up the trunnions a bit and see if with years of wear they have gotten too smooth.

May not make sense - but!

I think I would be looking for a different cause/fix.

I never had 'new' trunions, but they appear to have been very smooth when new.

I would first look for wear that has caused the clamp profile(s) to have changed.

Then any other wear.

I took the trunnion lock wedges off today. The wear does not look excessive except at the very tops (as looking at the pix). There are no obvious tits on the trunnions to cause this other than going over the holes for the table locking bolts. They appear to be smooth, but I think that I will chamfer them a bit while I have the table off.

Does anyone know if this is "too much" wear Thanks
