People who have seen my shop dont believe me when I say it was tidy.
I get the urge to tidy up and reorganise it now and again but usually sit down for a beer till the urge goes away.

Charles, ive seen your shop. You must drink a lot of beer

Cheers Phil

You better do it quick. Seems like there is a time limit on when you can edit a post.

Didnt make anything today but I found out why I was having so much trouble with all the stainless knurling over the last week or so.

One of the knurls has its hole substantially off centre and the other has a hole that is too large a dia so its sloppy on the shaft.
I will order some new knurls, make two new shafts to fit and see what happens. It cant make the problem worse.

some time back I purchased two T-Handle Allen key sets. They came in a plastic bag so in reality they sat in a pile on my work bench. No longer. Today I used some 1" square unknown aluminum extrusion that purchased from a scrap dealer a few months ago to make a couple of holders that I could mount on the side of some shelves that I use.
I used my CNC Mill to drill the holes. While the drill cycle was running, I would put up the previous Drill bit and get the next drill bit ready. Rinse and Repeat.

Continuing to install the 3 Axis DRO on my HF 12x36" Started on the tailstock now as I have the other 2 scales on. Wanted a out of the way, hard to hit with anything, accurate tailstock measuring device. So, I am mounting the scale on the far side of the tailstock. Had to clearance the quill lock platform just a bit and make a new quill lock lever so it would clear the scale. Now am measuring up the locking ring that will go around the quill and attach to the reader head bar. Got it drawn, now need to figure out how to do it on the Rotary Table.

What it the dia of the eyepiece barrel? 0.9? inches (forgotten the exact size) was a common size for microscopes and cheap-store astronomical telescopes.
The telescopes are usually useless so are often thrown or given away. Might be worth a try to find some for experiment.

The barrel of the eyepiece on my Gaertner scope measures 1.118" dia. What I think I really need though is a lower power objective to make it useful.

I spent next to no money on a rototiller that the tines would not stay engaged on. I thought it was a simple fix, but not so much. Turns out that the gear that engaged the tines had about a quarter of it's teeth cracked off! Long story short, the manufacturer no longer make that gear. (it is specific in that it has an integral cog for a chain). So, I ordered a similar one that didn't have the cog . These gears are kinda hard, so I had to anneal them. A few days later, I got back to it. I bored out and chamfered all the un-needed stuff from the new gear . Next, I did the same thing with the old gear . Next, I set them on a few plates to maintain the reference faces and welded them together . I annealed it once again, and in a few days, I will try my hand at hardenening. Hopefully this works, otherwise, I'll have to find another rototiller.
