Making A Replacement Spindle For An ASV Skid Loader - Manual Machining 

I appreciate that!

I love the chips, breaking and dropping into the chip pan. After he turned it around and started on the small journals did anyone else notice the stringing chips made until the cutter got closer to the chuck? Minor problem but this does indicate the need for a center for support. With the center those strings would have been broken chips. Another reason for support here. The bigger the chip, the more deflection for the workpiece and the tooling.

I like to take big cuts in aluminum with my 11" logan and pretend to be one of the cool kids lol!

Wrong, a center would not have stopped the stringy chip. I have done plenty of this kind of work, with and without. Fine cuts, when you are going for surface finish, just make sting with some material. Some material is worse.

@@CothranMike LOL what are you on about??? Stringy chips are NOT an indicator that you need support, that's the most ridiculous statement i have ever heard. (the first indicator for the need of support is Chatter) Carbide is made via sintering, powders of various compositions get compacted (via a press) into a die/mould and baked after for the desired part and MOST carbides have chipbreakers designed into the mould "the funny looking top of an insert" but every tool has a radius (some more than others), the manufacturer of any carbide insert will tell you that the chipbreaker only gets any use when you atleast take a cut as big as the radius of the insert and even despite that the finer the feed the harder it is to break anyway because you reduce the tool pressure. And a insert needs that tool pressure to actually break the chip (the chip needs to be heavy so it can actually hit the top of the insert, where the chipbreaker is), why do you think that the first things you do if the chip does not break is increase the feed(or take a heavier cut)? If you look at an insert which has been used for heavy roughing, you will see the top of the insert the chips wear a "hole" into the top of the insert, where the chipbreaker is because the tool pressure is higher then normal use. If his deflection was as high as you think it was, you would see runnout in the part because deflection means movement. If the tailstock was out of alignment even a little and he would use it as support, obviously the spindle would have runnout and therefor be scrap metal, so doing it without support actually ensured that the spindle is running true in the end.. And despite the chipbreaker, some materials just are stringy, due to their additives in the manufacturing of the material. (that's why materials like "free machining steel" exists, because its nice to machine because of the high amounts of phosphor in the steel). I highly doubt you will even read 1/10th of what i wrote but stop commenting such nonsense.

​​@@FireGodSpeed CothranMike did some chatter.... Maybe he needs support...? 🤣🇬🇧

thanks

I'm attempting to correct this exact same condition at 68yr, but opted for a more manageable setup using a 24"x 48" 3 axis CNC router. Never say never. It will keep you engaged and rightly challenged every day. The CADCAM software alone will keep you entertained.

He'd need a gentleman's gentleman as well.

@@twotone3070 imagine being able to afford a few of those these days

@@grizzlyrideemwet1698 would be a lot faster using a CNC lathe.

Light cuts with carbide are still necessary. I usually try to hit my size with about 0.020 cuts, but that doesn't always happen.

Thanks!

The most basic rule when working around machines is never put your hands anywhere you wouldn't put your dick. I'm sure OSHA has a ton of videos made for safety training but everyone I've ever trained thats how I explained it. Most of them have kids today so they must've listened to an extent.

Safety glasses, no gloves. Dont leave machine, keep attention on machine.

@@mmm365 And NO jewelry.

Thanks for watching!

Thermal expansion is a real problem with all metals. Some worse than others.

Glad you enjoy it!

Yeah, it helps to know what is normal for different materials at different speeds.

Thank you very much!!!

I agree, they have their place, just like CNC machines. But I am not going to buy a skid loader to plow a parking lot or load dump trucks, which is what most people do with them. They are designed for tight quarters, where a wheel loader is not suited.

This was covered in an earlier video. Not an option on a gear head monarch.

It has been crazy! We should plan a meet up. Maybe when you come get your shaper, we can all load it up together.

I am under the impression that simply put is the indication may not be too necessary with stuff like this. I made a lot of skidsteer parts but the tolerances aren’t too critical

Indicating is not necessary on stuff like this. All of the critical features were turned in one setup.

I have some. They have their place, but for something like this it's not worth my time to set-up.

I have ran several of them, I still would take a good wheel loader any day of the week. Skid loaders whether tracked or tires, just do not have anything I need for ability. And I don't like the ride.

@@TopperMachineLLC I can see your point. Here are large forklift and a loader is a much better fit too. However if you are putting septic systems in town, grading small lots, landscaping or have an aggregate plant to clean up around and so forth with ll the attachments available they are handy as a shirt pocket. But useless unless we can fix them.

Thank you,

Thanks Paul, we did.

I'll talk about that in the follow-up

@@TopperMachineLLC Thank you Josh, I shall wait patiently, Thanxxx.

I also have made similar stops. One in an upcoming video.

Possibly, but that is more camera and editing work.

At 1:25 he says the material is 1045PG&P

@@markat9576 TG&P - turned ground & polished. Silicon killed medium carbon steel. Equivalent to C45E [iso] also a poor welding choice due to the extra carbon, but he knows that. Wire welding will do better than arc with fluxed stick

Customer specified how he wanted it fit. Also, he is a very skilled welder.

all standard on the Monarch. Goofy threads on the Lion.

Why are you YELLING?

Wanted to make sure he heard me

No, made many spindles over the years with 1045 and 1144 and never hardened them. They are still all running strong.

Low end machine tools have the dial read radius. Monarch, Lion, American, etc read diameter. I also have the DRO set up for diameter.

Minimal burr, simple clean up with a thread file.

I have done a lot of spindles over the years. The two common materials are 1045 and 1144. Never had one fail yet.

sandvik.

@@TopperMachineLLC Sandvik what ?? What grade ??

bearings on the shaft are a slip fit for adjustment.

On the shaft, no. The distance that is critical is in the other piece with the races.

I shoot for the smoothest I can get. I have seen some rough machined ones seal, but I don't like that.

I have my DRO set up for Diameter, and the Monarch and Lion are diameter on the dial. It simplifies life to have quality machines. The low-end machines have dials reading the radius.

@@TopperMachineLLC Thanks! Makes a lot of sense. Hope you had a Glorious 4th!

Ive been doing this a very long time and never had a problem.

bearing failure actually was the cause.

Could be anything from proprietary technology, experimental work, customer preference/liability, the list continues. Anyway, he's not filming. It's an electronic camera recording on memory media, not fillm.

There are a lot of reasons. Whether it is proprietary or customer asked not to have it filmed, I have to respect their wishes.

​@@The_DuMont_Network its film not fillm

I agree, but some equipment is not worth repairing.

@@TopperMachineLLC This may be true, Josh, every job you can get in your shrinking economic work environment, every job, keeps you and your family fed. Plus we enjoy watching you use those wonderful old machines.
