Stuck Chuck

I started making the little pins I'd figured on, and they didn't work out too well.  So, scratch that and *hmmm, why not use something you already have?  Like a dull drill bit for the pin?* 

 Hardly any digging and I had what I needed. pinned the two holes, added some paper scratch protection to the sides of the head.  Mounted to the mill table, and it popped off with a little effort.

It's getting lighter...

 

Next up is to strip it of the parts and pieces, clean, oil and reassemble.  The old super maxi  ultrasonic cleaner will be put to work, if only to justify it's existence.  One thing that is really important is the depthing adjustment of the worm gear.  On the right side of the above picture is this "screw".

I have to get that back right, so now I have a documented position to return to.  Internet can be helpful.

Next up is pulling the spindle-bearing pack.  I'll need a pin spanner for that.  This is the nut that has to be removed from the back in order to drive the pack out the front.

the nut has two holes for pins, and the screw locks it in place

I've seen pin spanners that look like dividers.  Super neat.  But in a pinch, you can use a modified All-16ths wrench.  Drill two holes, add pins, and Viola, instant adjustable pin spanner.  I think I have a cheap-o that would be a prime candidate for this.  That's the next step.

One other thing I need to do is get a project pan for it.  They sell blems at the restaurant supply for $4.00.  Probably more now, but they are available locally really cheap.  Heavy duty for industrial baking.

And I remembered to mark the chuck, jaws and back plate so I can reassemble it like it came to me.

I should make an etcher

So far so good.  I usually go too far too fast.  I'm taking this little cleaning project slow and steady.

Tool Pron

Brown and Sharpe 0 Dividing Head

I finally saved up for one of these.  And it's here.  The BS-0 dividing head.  These are so useful for creating gears, flutes and splines.   I found an old one at the Rodent Urinal and Machine Shop years ago.  It was beat on, and rusty and I could never get it to work.  So I got this one.

This is on Ebay, same model and manufacturer

Now, a well known issue is the unit is full of chips and grit from manufacturing.  Mine has a very stiff chuck.  I reckon it's just like every other one out there.  Double plus ungood is the back plate is so tight, there isn't an easy way to remove it.  This 'tuber had that issue.

 

He didn't detail how he did it.  Just said a spanner and an impact.  I don't want to break anything so I'm working on a brake I can make with pins that goes along side of the housing and catches two of the holes in the direct indexing plate.  I thought about catching only one hole in the plate, but I don't know if it will be strong enough to hold against the torque.

Those two, or the one in the middle?  hmmmmm.....

 

Had to do some measuring to see what I need to make.  And I came up with this on my thinking pad.

I really don't know how close the two holes are to the flat side of the body of this thing.  So, I need to make two pointy bits to fit into the marked holes and make a scratch on a rectangular piece of steel.   Then, I can make the proper placed and sized holes to slip the pins in and hold the spindle from turning.  Maybe I can chuck up some hex and use it like a bolt head to try and removed the chuck and plate.  

There is another owner down in Austrailia that showed pulling his apart, and the bearing on it was gritty.  He made some additional parts and got a new bearing for it.  He also made a pin spanner for the back nut.  That was pretty wizard.

All Bundy Bears Shed videos about the dividing head are real time.  He doesn't speed anything up that I remember.  He shows some detailed lathe work making the parts he wanted.

I need to quit putting things ahead of the pantograph.  I got the itch to get that done, other things seem to pop up as well, but they don't scratch the pantograph itch.   Not by a long shot.

I'm Officially Confused

Is this a "lost in translation" issue?  Am I missing something?

Perhaps a petite E-normus?  

 Does the Titan come in small or medium?

Mind Boggle....

Drain Bamage

Have you ever had your drain bamage add a soundtrack to something you are watching?   

Have you ever heard it so loud it drowns out every thing else that's on the real vid?

My headspace was in a strange place today.  

I HAD TO DO THIS SO IT WOULD QUIT PLAYING IN MY HEAD.  

CLIPS USED BY PERMISSION!

How cool is that?!?

Feast your eyes on the exploded diagram of the Logan cross slide (LA-747) and the pivoting part of the compound slide (LA-746).  Of particular interest to our proceedings today is the pin (LA-744).  There are two, one each side.

 

While I have some time today, I'm gonna get some idea of what the pins need to look like.  I gotta make two to replace the two I murdered trying to remove them.

 The plug on the bottom of the pivoting part has a complementary angle for the plug to push against, effectively locking it into place.  Logan calls part LA-746 the swivel.

Part 19 - bottom view

Angles on the ends, length and diameter of the old pins.

 

60° ends

 

Length is 28/32" = 7/8" = 0.875"

Caution!  PARALLAX ERROR!!!!

 

Diameter is 0.252" in a 5/16 - 18 tapped hole.  Tap drill size is F or 0.257" leaving 0.005" clearance.

Uh... no, I won't make it that big again

After these are made, there will be a bit of fitting to make sure they work right.  Then assembly to see what else I need to make to finish up the taper attachment.  Hooooboy, this is getting exciting.

Ye Olde Drill Press

I started working on the small workshop drill press back in June.  Needed it for some specialized work.

https://budgetmachining.blogspot.com/2022/06/argh-etc.html

One of the things I found was the return spring was yuk.  I bought some new ones off Amazon.  I mean really.  It took me too long to figure that out.  Instead of a 1/2 inch think truck spring that was on there previously, I ordered some skinny ones that fit it perfectly and work fine.

Return Spring

After that was done, I went to work on the stupid little pointy pins that hold the top slide (compound) on the cross slide.  First one wasn't too much work.  Second one though....  1/8 inch drill skated off to the side.  I put a tap in the hole.  Gripped it with the chuck, and gingerly tightened the clamps down to the angle plate.  

 

That lined it up enough... the letter D drill didn't scrape out the threads.  I  drilled it down a ways.  Then, I went again with the 1/8 inch.  

 

The easy out would pull loose every time I worked it.  I finally got the bugger out enough to let me get to it with a small tweak-type screwdriver from the bottom side, where the tapered plug lives.

 

FINALLY got it worked back enough to remove the compound.  I had to push the pin through to the inside to remove it.  It was just a couple thousandth's smaller than the threads in the hole.  Sakes, what a mess.  But it's done.

Now, make some new ones.... clean, oil and assemble.  Should have a taper attachment running on the Logan shortly.  I'm thinking about using the other compound for a milling attachment.  Maybe.

Like this:

That's the preliminary plan, anyway.

Thanksgiving Update

I gotta go to bed, I'm bushed....

Pickles Again

Niece needed a ride home from scruel and there is a small, new veggie stand on the way home.  I stopped and nosed around.  I found some small cucumbers.... Persian Mini.  Never heard of them before.  I was getting a few when the owner came over and we started talking.  I wound up with a 20# flat.  (About 9 Kilos for those that use SI units.)  I brought them home, rinsed off half of them and put them to soak in a brine.  

I picked up a couple gallon fermenting jars from Vally Verld late last year.  This was their first "voyage".  They have plastic lids with a water lock on the top.  Very cool.  As the ferment happens, the gas expelled bubbles up the trap but no air comes back through.  Keeps the system running like it should.  Anaerobic.

 

Our happy friend that causes the ferment lives on the cukes.  It's lacto-something (acid, bacillus, Jim Backus??).  And it makes a nice, scummy white slurm over time. That means we are on the right path to amazing flavor.  Light is NOT their friend, so I wrapped the jars in butcher paper sleeves.

Slurmmy goodness

 

The smell makes my mouth water....  It's time to give them a try.  They say to wait 5 days, but I waited 2 weeks.  I like to give them time to get.... stout.

I'm no hippy dippy weather man, but I do like the taste of these.  I'm not a back to nature type.  I do this for the taste.  Dad told me when he was a kid, pickles tasted totally different than the vinegar ones we all know.  These are like what he got when he was a kid.  Brother, they are really tasty.
