Making Modifications to a Stock Boston Gear 

I was more wondering about the table tilting down under pressure. That looked to me like most of the problem.

Yup going to have to tighten up the slide on that ram or there will be something broken in the future pressing on it. Way too much movement. Funny how well stuff like that shows up on video when you can barely notice it in real life.

@@bcbloc02 yes I was waiting for that thing to snap

Mr. Wilton, I looked again at the ram in relation to the lalthe handle behind it. The ram is moving all over the place. The table is flexing a bit as well, just not to the extent of the ram. I may have to install a camera in my shop so I can spot similar issues!! bcbloc02 made a good call.

What I was going to say has been said before. Thanks for your videos Kieth

I noticed in his videos from years ago, he let stuff just fall from the press onto the concrete floor. Doesn't look like he's interested in good advice from professionals like yourself.

yes, didn't like that

And when it hit the concrete...

I saw that happening and looked away waiting for the sound of the broach snapping into many smaller pieces.

Yeah, right at crotch level

Is the Arbor worn out? That side movement didn't look good.

Industry just wants CNC operators who can babysit enormously expensive, high throughput machines used in manufacturing. The market for people capable of repair work is relatively tiny.

@@5tr41ghtGuy That's totally untrue. The market is in desperate need of skilled tradesmen. There's especially a need for skilled machinists because all the skilled/smart machinists are getting old, and the kids who are smart/intelligent/intuitive are doing other things like university, and are taking desk jobs. There is a huge need for them in the machining sector. And the notion that you can be a CNC machinists without being skilled is completely wrong. Go take a look at Peter at Edge Precision. His job is the one that's most in demand. He's semi-retired and keeps a couple of his machines at his machine shop that he sold. So his generation is on the way out of the industry. Same goes for most other trades, from plumbing, to electricians. There's an over abundance of unskilled labor.

@@xenonram your not watching a skilled machinist....

You'd think he would at least raise the bar to release the broach from binding.

@@Craneman4100w , he saw the danger as it was happening and changed the position of the broach so that the broach could be used with less peril to the broach. I'm sure he realizes he's going to have to work on the tolerances on his press so that there won't be so much side ways pressure.

@@lwilton It's a pity that you didn't learn basic hand tool work, it can get you out of a lot of problem situations! If you decide it will be botched, then it's going to be!

@@lwilton Who was talking about beating techniques into anybody? If you don't want to work by hand that's not my problem! My idea was to let people know that this can be done by hand, just not many people think of it. I repeat, this can get you out of a difficult situation sometimes.

@@lwilton That is a change gear for threading, so if he was restoring his lathe, that job could have been done last after the machine was assembled and running- very odd that a guy with the ability to restore a lathe would need to send that simple job out to someone else.

There's a lot of assumptions going on here. We don't know what this gear is used for. (Recall, Keith said he wasn't sure.) Maybe he wanted it broached rather than spending an hour or two with a file and getting a crappy fit, or spending several hours with a file and getting a great fit. When Keith can spend 3 minutes and push a broach through. Maybe he's an older fellow that prevents him from doing fine file work due to a disease, or eye sight, or just old age. Maybe he's a young fellow that suffers from one of the first two aforementioned afflictions. Who knows. There's often a reason something's being done a certain way.

@@xenonram Well, you certainly added a few more assumptions to the list. From the number of comments, it seems a lot of people are asking why a person outsourced such a simple job- maybe the owner of the gear could post an answer.

I think the thin section of the gear aggravates the broaches bite so that it is drawing in too much.

I have found while making videos that microphone location can make normal breathing sound excessive. Like when your mic is on your chest and you're looking down. Not sayin' you shouldn't take care of yourself...

Sad thing is that he just "restored" that press.

I noticed this as well, something definitely sounds off to my ears.

I was also cringing, but I think us preaching to Keith is a little like trying to teach your grandma to suck eggs.

@@graymouser1 I agree and also I have have seen no (to date-I am a new fan) of Keith answer any questions. Strange.

Teaching Grandma to suck eggs sounds pretty rude! Perhaps my comment should have used "one positions" instead of "you position" and "one should" rather than "you should" so that other viewers of this video might realize that my advice doesn't just apply to Keith.

@kevin Martin It's an old expression, and it implies grandma already knows WAY better than you.

Of course he can. It's easier, comes pre heat treated, and cheaper (when you value your time, the cost of the material, and heat treating). And he might not have had time to do it. You know he has a regular corporate job as a Bayer crop scientist, so his free time is limited.

not a machinist but was thinking the same thing. At least indicate it to make sure the gear is centered, and not just trust the chuck. Facing is one thing, boring is another. I assumed either reamer or boring bar.

Fits right in with the less than precision measurements on the width. "It's close...that's good enough."

@@AffordBindEquipment if it's off center a little, the drill will flex and "find" the center. As to the tolerance, it's a keyed shaft with a set screw that's going on a lathe. It's not a piston cylinder.

He tends to be a bit of a hack when doing his work. There's no way the drilled hole was as good as boring.

@Philip Crow: Well, that's a good excuse for doing a shit job. I won't be hiring a hack like you anytime soon.

If you recall, he's duplicating a part, and he said the original had the set screw 90° apart.

@@xenonram I did not catch that in the video. Thanks for correcting that.

As I recall he sent it out to a speedometer shop. There used to be a lot more of them before electronic speedometers became the standard.

oops, I see I should have read thru the comments before adding my own...

Yes but that implies a certain degree of forethought.

@@jonka1 ha ha

good question.

Let's hope not

That was not one of their better castings. It looked like something from China.

Just a thought but perhaps the lathe is in pieces awaiting a new gear?

@@littleworkshopofhorrors2395 That is a change gear for threading, so if he was restoring his lathe, that job could have been done last after the machine was assembled and running-

@@oldschool1993 i bow to your greater knowledge of charge wheels, but that doesn't stop the rest of the lathe being in pieces. Just possibly he needs to screwcut a part to make the lathe usable?

@@littleworkshopofhorrors2395 Hmmm- not sure how this gear would help him screw cut a part if the main spindle and chuck are disassembled- if the main spindle and chuck are functioning, then he could have done the gear work himself.

@@oldschool1993 just thinking off the top of my head. How about he doesn't want to use the lathe till everything is perfect. I knew a chap once who rejected a lathe because of a minor spot of rust,takes all sorts.
