Nice job! Only thing I did differently was to cut away half of the tip. It gives the oil a place to go to get around the ball. A needle file V-notch on the tip would do the same thing. The concept is really stolen from a shop vac nozzle. Ours have a relief notch on the side of the opening so it doesn't seal to the floor.
I was in such a hurry to test it I never got that far but I did make sure the tip is short enough so it doesnt set tight up against the ball and the oil pressure would push the ball out the way, It does and I am wrapped with the simplicity of the whole project.
Why dont they come with this from the factory.
Bruce, It's their Deckel clone. It comes with work heads and fixtures that expand the little grinder's functionality. It's not German craftsmanship, but I'm excited to encounter those "I can do that" moments that happen when you have the right equipment!
made the wife's Christmas present, a mortar and pestle. She had a small one years ago but it disappeared in one of our many moves and she's missed it, so I figured that this would make a nice surprise for her.
Making the mortar was a bloody miserable job. Used the trusty rusty 4x6 to cut 3 1/4" off a chunk of 3" supposedly stainless round (that's what the scrapyard said and charged me for, but it's magnetic), then step drilled the hole out to 1" on the mill. Faced off the bottom and turned it round in the lathe to start boring out the cavity. Several days later, ta da!
next to parent material
used math (well, technically a Math professor) in Excel to calculate all the bore depths and radii for the hemisphere at the bottom in 2.5 thou increments. Didn't exactly go to plan as you can see but the "texture" should help with the grinding, right?
donor material for the pestle. Definitely stainless and they periodically show up at the scrap yard. not sure what it's for, but it's well machined and looks like there's the remnant of a carbide tip on the end. Who knows? Anyway, the future pestle is the piece in the middle
turned the business end with my boring head ball turner
then intentionally added some grooves for extra grindingness
first time ever using the cup center to turn the taper and tidy up the flank of the pestle
all done! The hand end of the pestle didn't come out quite the way I intended, but it'll do
it's now wrapped up and stopping the Christmas tree from blowing away
In the shop a bit this morning. I’ve been working on repurposing a medication bottle. I take some maintenance meds and their mailed to me. This small no spill oil container is for my bench for hand tapping
Also got a couple of other projects done. One was adapting a flask holder to an orbital shaker for the lab, so we can use one of our incubators to grow bacterial cultures. Both parts were crazy cheap off Amazon, so it was worth the effort.
Second was spending 3 days at the beginning of the week with a very nice guy from Olympus to test drive a laser scanning confocal microscope that I'm rewriting a grant for. He brought an all singing all dancing version with him that is about $550,000, but we're asking for a simpler one for just $330,000
here's a mouse brain lesion. Blue = nuclei, green = actin (a cytoskeleton filament), not sure what red is labelling (colleagues work)
next up is an autofluorescence image of a fire worm (polychaete annelid) - the spikes are calciferous and break off in your skin causing either burning itching sensations or long term numbness
close up of the spikes (chitae?). My colleage was super excited by this image as some of the autofluorescence is seen only in the tips of the spikes, which might be the causative agent of the numbness. Long way down the road, but that might lead to new anaesthetics. Or not, given that it took over 18 months for the numbness in her finger tips to wear off when she was collecting them.
now my stuff:
a green fluorescent protein expressed in neurons (if you look closely you can see axons and dendrites)
a different construct expressed in the germ cell niches at the end of the worm gonads
and a final one expressed in the intestinal cells - the nuclei are the bright green circles
I love playing with microscopes, you can get some truly beautiful images
Had some time this morning to make a duplicate hub for a ceiling fan setup I’m making. Second one was alittle faster but not by much. The hub is 5” diameter and the slots are 1” depth. Now to finish the rest of the components.
I finally finished a 5C setup for my lathe.
A friend gave me a closer and some collets.
The closer was too short so I lengthened it with a sleeve.
I made a spindle adapter for the tail and a tapered sleeve the the head.
It works great.
Last couple of days i've been working on the little Lada, working on smaller jobs first of which was mounting the trunk lid and drilling, tapping and installing gas struts, i had to modify the mounting holes to accept the new style ball mounts, this left me with a empty workbench, so i got the dashboard on there to work on fixing it, i've had no luck in finding a new dashboard so i'm using body filler to fill the holes and plan to use bedliner to apply a textured coat over it. I may need to start more than one job at a time because the body filler seams to take long time to harden, probably because of the cold.

Things that I have accomplished today.....
Installed my new set of parallel keepers. Ok, they are just springs.
Started making my wifes present. She made me promise not to buy her anything. She didn't say not to make anything. It will be finished tonight come hell or high water. More on this when its done.
And I took my blood pressure. Might be time to call my Dr.
Today i had very little time to spare, but i did get my hands dirty, i decided to do some mechanical work on the engine, with the radiator removed i have great access to the front belt drive, i know the water pump is leaking so it needs changing, also the alternator is not charging an is the old style with external regulator so it needs to go as well, to get better access i first removed the shields from under the engine, they have some surface rust so i'll clean them up and undercoat them, but the surprise come in the water pump, it is the original one that this car left the factory with, i found the date and is from 1981, this confirms that this little 4x4 has only 57 000 km. Here, i'll be doing couple of modifications first of which i will not be running the mechanical radiator fan, also i'll be making some more room and i'll be using the biggest radiator i can fit and twin electric fans also i may install a A/C condenser up front also i be using a updated water pump to help with the cooling, i'm sure in Russia at - 50 celsius this cooling system works fine but here is insufficient.
I was able to finish my throw lever tonight. It came out the way that I planned, but I would do a few things differently if I made another one. I would make it more petite for one. It needs to be pretty tough. The rifle does get deposited into a dump barrel rather hastily.
The power ring is much easier to turn with a lever on it. Some stages could have targets from 5 yards and out as far as 350 yard at one of the clubs I go to.
After more than fifty years I've finally come to the realization that I am destined to forever remain the 98-pound weakling on the beach. Charles Atlas is just not in my cards, period! So I was some disappointed when even the thrift store would not accept my practically unused weight set that had been gathering dust in various parts of the house. What to do with the stupid things now?
The rejected bar ended up back the house, and as I was starting to break the thing down for scrap I looked at the two end collars sitting on the bench. Just crude cast iron things that stop the weights from sliding of the end as you crumple under the strain, but wait a minute. They look kind of like.....
So went to my stock rack and pulled out a length of 1-1/4" round 1018, cut two lengths and threaded them for 18 teeth per inch. And after a little boring on the two cast collars I threaded them for 18 teeth per inch as well. Oddly, I hit the sizes on the money and the fits were really nice.
Two more pieces of round, some more turning, and then to the press.
And you were right, they do look a bit like jumbo machinist jacks!
Made a slitting saw arbor with a 3/4" shank for 1" arbor saw blades. Started from a 1.5" bar of 1144, so ended up with a lot of chips. Micro-mark 7x16 with carbide tooling; actually seemed to work out fairly well despite all the horror stories you hear. This might have been my smoothest project yet - writing up a plan beforehand helped a lot.
It machines really easily and I guess it’s already pretty strong without further heat treating. Plenty of people talk about how neat stressproof is other than the cost, and this is what McMaster had. Should I have picked something else?
Today i had some free time so i did some more work on the little Lada, started by sending on the dashboard, is too cold i'm having to leave the body filler to cure overnight. I use 40 grit sandpaper on a block to flatten down the high spots, this took about half an hour and then i mixed up a second coat and apply it to all the places that needed it. The cap over the instruments has the worst damaged so it will need much more body filler, so i'm building it in layers. I left the dash to cure and went thru my spare parts, i found this big radiator, is from a turbo diesel, it has one outlet damaged but i should be able to machine a repair nipple on my lathe, also got out couple of cooling fans none of them really fits on the out side and are to small for the inside i'll keep looking for bigger if i don't find i'll modify the ones i've got. When i was dealing with the cooling system, i got out the spare water pump i got couple weeks ago, it's almost new, i removed the housing, made a new gasket for it, and gave it a wash with some soapy water, you can see the new design on the propeller this helps to move the coolant faster in the system, i also removed the alternator that i'll be throwing straight in the bin, it wasn't even installed right, and it isn't charging, the Russians are terrible when it comes to electrical, i'll be looking for a better replacement, probably from a german or a french car.
Thank You Mike, unfortunately is worse than being owned by Ivan the Horrible, this is an ex government vehicle, bought at an surplus auction by a outlaw guy how did some of the repairs himself and others had done by an even worse body shop. That said i've had good experiences with ex government vehicles, my daily driver use to be in the president's motorcade as a support vehicle and its been cared for extensively, but unfortunately the department that had the little Lada didn't care that much for it.
Fixed a folding camping table. Two tabs had broken off ages ago and were fixed, one tab broke off this summer and the other was fine. Replaced both the "unfixed" tabs, just in case
Broke my glasses the night before going on a trip away with the family. Once my wife guided me to my spare set of glasses I fixed these with a piece of alu, some JB weld and a Dremel. They're really nice titanium frames and there's no money in the kitty right now to replace them.
Also cleaned and regreased a drill chuck without screwing it up, which was a pleasant change
Today i spent solid 7 hours cleaning my machine shop, there was lots of garbage and scrap all over the place, also all the machines needed cleaning, and the tooling got reorganized, sure makes a difference, now i can move around and get to all my tooling.
