POTD- PROJECT OF THE DAY: What Did You Make In Your Shop Today?

[mmcmdl]

Today's job is to pack up things and get them out finally . I'm falling behind on this as the weather has been nice outside .

Saved a screw up - tap spun in the last hole in a cast iron back plate, so I drilled and tapped it to the next size up and loctited an old 1/2-13 bolt in the hole

Cut it off with a hack saw and faced it again in the lathe

Drilled and tapped for 3/8-16 (was holding my breath that it didn't break through!)

Worked a treat!

@mattthemuppet2
Love it when a plan comes together!

Home made heli-coil !

 

[mattthemuppet2]

Thanks, i was very relieved. Funny that it was the first time I've needed a helicoil and I didn't have that size

I guess I didn't catch that the shaft didn't wear round. One would assume that might have been the case.
If the shaft has centers, turn/grind round and make a new bushing for the new size?

Of course, that's harder to do when you are rebuilding your lathe...

No working lathe is one of the challenges. That and no actual experience running a lathe
Good news is Clausing has the worm gear and worm bearing, checking on availability of the bushing. I find it astounding that any parts are still available for a 55 YO machine.
Not inexpensive worm gear is $104, bearing is $11 would guess the bushing will be $40 plus if available.
Sort of back on track again until I'm not. Was thinking I should part the thing out and move on but hey will just toss more money at It. Like owning boat I guess

Alright, finally finished my dividing head adventure. Got this a couple of summers ago for a really good price. Came with all the plates, a thread protector and a single back plate.

Great forward to now and I have a collection of chucks and a face plate I can use with it.

First, stripped out down and cleaned it and the tail stock. Very little wear, lots of crusty grease

Then set about making a couple of back plates and modifying the one I have

Nice piece of stress proof that a friend gave me.

Turned

Drilled

Threaded

That was for my 4" three jaw, next up was for a really nice face plate I picked up  years ago to make my own rotary table

Mystery steel

Turned drilled and threaded (used the dividing head as a go gage!)


Then turned a spindle nose copy and left it there - in theory that should stay perfectly true for each of the back plates


Threaded on each back plate in turn and turned them down to match their chucks (didn't take a pic of the large one, nasty stuff that CI)

 

[mattthemuppet2]

Then set up the dividing head to use like a spin indexer

Here's the 4 jaw back plate after, ahem, a slight accident and a hail Mary

Then mounted up the 4 jaw and used it to hold the face plate so I could open up the counter bores a smidge

After that it was the face plate back plate (!)

And the 3 jaw. No pics of that as I screwed up one of the counter bores and it looks kinda ugly

And finally, the family shot!
