Back in high school I had used a collet chuck on a project and always wonder how they were put together. Needless to say MR. Symonds would not let me take it apart to check it out....lol Thanks for showing an old guy how this finely works.
My shoulders (story on its own) and your video inspired me to pick up a Hardinge-Sjogren Speed Collet Chuck 5CD4. I was eyeing up the Pratt-Burnerd Quick Collet Chuck - but I didn't want to part with $1700. You convinced me to take a chance on the H-S. After reading what I could find on the subject, folks seem to like them. So, I found one on Bay and when it came, I ran your video again as I followed through step by step with you....and what a difference it made. Thanks for all your help. Keep the videos coming.
Mechanic here (and hobby chemist + electrician) WD-40 is the worst thing to have near rubber as most types of rubber gets dissolved by petroleum oils and here time is the issue, the longer it's in contact the bigger issue. Brake cleaner is in most cases more rubber friendly since it evaporates completely long before doing any harm. When doing brake jobs and if anyone have used some spray oil or antiseize on rubber parts like the caliper boot and sliding pin boots they swell up, take in water and it's all rusted out in a year. I clean it out with brake cleaner and then lube with silicone grease
Press in zerk fittings are called "drive type" you can get them at SAE Products, Zerks Plus, Grainger, McMaster-Carr, or M. Brown fitting specialists. Yesterdays Tractors has a few threads on how to remove or install them. I'm used to seeing this type on larger machines but in areas that are not in a normal traffic area of the machine, or well recessed.
I watch you folks to learn how to wrench better, think over problems, and to problem solve in general. Got stuck on a bent welded steel gate hinge today. Tried zipping the hinge pins all off, but not until a total stranger tried to help, did I get out of my jam. All the tooling and machining channels are full of physics, math, and chemistry knowledge. Don't stop learning folks and know when to accept help! Thanks James!
Brilliant video, James. Thanks. While Gunsmithing I love Simple Green to break down the gunk and the Ultrasonic with Dawn dish soap and lukewarm water to remove it.
I got the larger version for the big collets. Works nicely. It was all gummed up and wouldnt even spin because it was really hardened up in there. Great video. I really should get one of these.
Guys, I don't know if you noticed and maybe James might be brave enough to admit it, but I think he runs a discotheque, 70's style, when not filming a video. What'd think?😁 Love the episode. it is so Zen zone like to take a piece like that and make it up from a state, to a pristine condition.
Really informative…the only thing I might suggest is not to use grease …it just acts like a magnet for dirt and metal chips, and hardens over time…I recently bought an unused Pratt Griptru chuck vey cheaply because it was seized solid…upon stripping it down, the factory grease had set that hard it was like set varnish, and had to be scraped off, once it was cleaned out it works like a dream.. All I’ve ever used on lathe and drill chucks is a light oil like 3 in one, and have never had any issues. There are no high speeds and pressures on the parts that require a moly or specialist grease. It also makes any future rebuilds much easier..
Nice work as usual James, one suggestion, after washing and rinsing steel parts why not use WD40 to displace all the water? After all that’s the original use for it.😊
I haven’t finished watching yet but, If you don’t have a Horrible freight ultrasonic cleaner or another brand, they work great on chucks. You don’t even have to put it all the way in, just rotate it.
I dont have an ultrasonic cleaner but I presume you use dish soap in yours regularly. "Dawn" brand dish soap is great for grease and grime. One drop will clean three ducks :) Love those Hardinge Collet chucks... cool find and nice save
Yeah I really want to make a flat to d1_3 adapter for my lathe too. Since it's 5 inch chucks on mine and d1 seems to start at 6, I may make a mini D style adapter for all my plain back chucks.
@@Clough42 We had a sudden (and unexpected) cold snap earlier in the year where the temperature swung from 10-15C down to below zero overnight and caused condensation on anything metal in the workshop.. I went back in there after a few days to find surface rust all over the mill vice and table, lathe chuck etc - fortunately not the slideways! The joys of humidity.
i bought a second one of these for parts (needed the hand wheel) and it was clear that someone couldn’t figure out that gear mesh and had ground away lots of material in trying to get it back together 🙄
When you use the ultrasonic bath for cleaning, what is the optimal temperature? I understand that hot water is best for dissolving grease, but cavitation caused by ultrasound will not occur near the boiling point of water.
Yeah! Cleaned, lubed, and then...whoomp, whoomp, whoomp. ;) BTW, I think James should have shot some fresh grease through the zerk while it was apart just to be sure there wasn't any grit lurking in there.
Worst case if you can't find the felt seals that size you can buy sample packs of industrial felt from felt suppliers rated for seals and they give you several 4" pieces in different sizes, and you can just cut your own.
If I had gone to a store, I would have bought Dawn--not because I believe it's better, but because I remember their commercials after the Exxon Valdez spill.
I have a lathe with D1-4 spindle and it also have 3 studs. You might verify if it is D1-3 or D1-4 since D1-3 is not very common, but D1-4 is very common.
All of the Hardinge Speed Chucks I have seen which are Camlock (even though the spindle may have more than three stud holes on the camlock circle) use only three pins on the chuck. Same for Jacobs Flex Chucks. These are considered medium-to-light duty chucks.
So how did it measure after the clean? I would have stuck a grease gun on the nipple and pumped it through just in case I decided to grease it in the future. You wouldn't want to be pushing in crusty grease.
Did you catch the dot on the smaller gear? I had to look for a while on mine till I flipped over the gear saw the dot, and the sun gear has two 0 marks.
Next time when cleaning old chucks, after disassembly, put them in the dishwasher with mild soap. I'm sure the wife won't mind, and if so, it's easier to ask for forgiveness than permission.
What are those hex L wrenches you’re using to assemble the chuck?? I love the anodized aluminum holder. I have wiha wrenches but the plastic holder doesn’t hold up too well.
I was a mechanic in a factory for about 10 years and dealt with all kinds of grease fittings and I'll tell you what, press in are the worst style. Once there messed up there's no fixing anything about them. You just have to drill and tap for the pipe thread kinds. And hope you don't over drill into anything important behind it. They're just awful and they never seem to be as robust as the threaded ones.
FWIW, I've had REALLY good luck with ZEP HD floor stripper for cleaning stuff like this. It will remove / dissolve some paints and definitely use rubber gloves.
