This is all really heartbreaking Jim, Ang & I feel just terrible about what your all going through.

Hi Jim, Thank you for the updates. Sad as they are, at times, they are reassuring because we know you are still with us.

Be blessed.

Hi Wayne,

1/4" x 28 is a standard UNF size so not an odd ball.

Hope that helps.

I just wish that you didn't have any reason to write all this miserable stuff !!!

It remains totally beyond comprehension, all that you folks have been through .....
Nice Tool buying there Charlie.
The lathe tools are definitely worth it, I have several sets here. The reason being that it is usually cheaper to buy a set than to buy replacement tips.
And your post reminded me that I need more tips, so thanks. 8)

Thanks Dave.

They really are great Lathe Tools.

Thanks all, I feel terrible always having bad news guys :(

Insurance sent out a team of builders and they have pulled up all the floor coverings and taken to the tip. The floorboards are now starting to dry and the stench isn't as bad. They have replaced the fridge, freezers, air conditioners and a lot of other stuff, lots still to be assessed though. Steam room has needed a lot of attention with rust due to the humidity, I had a couple of hours to get on top of that yesterday. Our gardens and flower beds have pretty much been trashed.

The houses haven't been touched since they went down on NYE, the older ones have been sprayed with PVA glue to try and contain asbestos fibres.

The NSW govt has now got a statewide contractor so the houses should start being cleaned up soon. But people have already lost 2 months of their 12 months of insurance covered rent. They now have to build to a higher fire rating and their houses are unlikely to be rebuilt in 10 months.
I have eliminated that side slop with teflon bushings. You can cut a slot in the bushing with a slight V opening towards the outside of the bushing. It will then allow you to push it onto the journal until it snaps into place, leaving no gap in the spacer. I make the spacers out of black delrin, but you can byr white teflon ones with different i.d.'s and thicknesses as well.

I have done the exact same thing on gear shafts in large scale electric locomotives that are driven by a worm. In one direction the worms rotation pulls the worm gear into a nice central position providing full gear tooth surface area of contact. But in the opposite direction there is enough slop on the worm gear's shaft to allow the worm gear to be forced to the side so the worm is only engaged on the very edge of the worm gear and only getting about 1/3 of the proper tooth face surface area actually engaged, so very likely to rapidly wear out / strip out when under load. I have several thicknesses of sheet Teflon that I punch my own washers / gaskets from, and slitting the circumference as Doug has suggested works well for me in this application.

To add to the concept, I like to cut the washer / spacer on as hard a diagonal as I can manage using a pair of wire cutting dikes. This produces a chamfer on the slot, instead of square corners that are created by cutting with a knife. The chamfer allows the rotating gear hub to slide past without snagging on the slot trying to open it up, as might happen with a square shouldered cut. Making the cut on a diagonal like starting on the outside rim at 6 o'clock and cutting to the inside rim at about 8 o'clock, or as near tangent to the rim of the I.D. as you can make it, increases the length of the slot, thus helping it to lay flatter and only present a "tapered" line for the rotating adjacent parts to slide past, instead of a line that is fully square to the angular motion.

If the concept is not quite clear, I can post photos to provide a more graphic example.
