[@tylertc1]

Lol, I should have prefaced my original comment with "non-regulars" to the channel. You're exactly right though - that sort of insight is priceless and is exactly why I enjoy these so much. "Knowing" NYC CNC from the channel, I feel John's the type of guy to see that kind of feedback as priceless, and wouldn't be surprised if many of the suggestions go directly into the next batch / design.

[@45calshooter]

agreed. As a manufacturer you should be made aware of what needs to be and how much or little. No disrespect just not "a yes man". I made good monies doing just that.

Not sure where some folks get the idea that John is a know it all. I haven't watched a ton of his vids, but I've seen a few occasions where he's shown a mistake he made on a job and could've easily edited it out of the video. My impression of his channel is that he's not just showing what he knows, but also what he's learning.

[@gordo3di]

I must say AvE is brutal but he has expanded my manufacturing and design knowledge immensely. I've actually learned more on this channel (and johns) than most 4 year colleges can teach. I fully agree with the line "It's the little things that matter". I can't tell you how many people have seen a poorly installed "sticker" and thought "well, what else is wrong". Great review and scary reviewer. AvE is a madman but in a good way and John seems to be a great owner who accepts criticism well. It's a VERY hard thing to do. One quick edit: It's very refreshing to hear someone understand what a business must spend to make money. "On order to make a buck he must have to spend 3 bucks". Most people simply do not realize this.

[@MattsAwesomeStuff]

This is maybe my favorite BOLTR ever, except maybe the first couple. I haven't learned much from teardowns lately, mainly is all the same stuff I've already learned how to recognize from previous teardowns. It was interesting to tear down an amateur-ish product, more feedback and tweaks on how to save money, why the design could be improved, etc. Feels like I got invited to the table at the process. I'd enjoy seeing more semi-professional BOLTRs and hearing why they maybe did things one way, how you might do them differently. I like how you keep in your mistakes too, when you think it's done one way and you find out you're wrong you take it back, not just edit it out. I think the world is made a lot better place the more people are exposed to role models not making a big deal out of being wrong. Also, emphasizing the value of criticism as an investment in that person, rather than an insult, the better. The less stubborn defensive knowi-it-alls and crybabies we breed as a society, the better.

[@aussiebloke609]

6:20 "Fair dinkum"...? Man...I haven't heard _that_ since I was a kid in Sydney. Getting homesick - hit me right in the feels. :-)

[@WatchWesWork]

Most likely he drilled, reamed, tapped, etc the holes complete from one side. Then he just flipped it and faced the other side and did the chamfer. So, if the register was off a little from one side to the other, that accounts for the chamfer shift.

[@Andyjpro]

He said they were NPT threads, so to get use out of that taper, you'd need to tap them from the side you intend on using them. OF course, I believe that statement to be a mistake in the lang-age dept because why would these be pipe thread?

[@Andyjpro]

My mistake, it's correctedI need to watch the _hole_ thing before commenting

[@jpkalishek4586]

sounds like NPT first then he corrects it later.

[@WatchWesWork]

It happens to the best of us...

[@dethadder0]

Could have been drilled and tapped on the machine, then chamfered by hand. This would account for a an error that is seemingly random. If it was an error due to a work piece being removed and/or repositioned, all holes would likely be affected.

"Luckily it's in metric" - AvE, on the internet forever

[@telecrate]

Including that star impact socket is a must IMO. I built one of these contraptions myself and using regular socket will not work as they chowder up after a dozen uses. You have to have impact rated ones. Impact rated sockets are extremely hard to find in certain sizes. In my case I had to use a star impact socket as the drawbar nut is square (G0704/BF20). Funny though, I used a brass bushing instead of a bearing as you suggest here...

[@stampingdieguy147]

AvE- The drawbar in your Bridgey is for a 2J (vari-speed head). They work fine for a J head (step pulley), but are made to project above the taller belt housing of the 2J. Both heads have the same spindle length, hence why they interchange from a manually operated stance. Not so with a power drawbar. I totally agree about the fasteners and such. Counterbored holes for SHCS or countersunk for flat heads would be way cleaner, and is the right way to go. It is a simple solution compared to other power drawbars (like Kurt), but the alignment issues don't work out. Some attention to detail was lacking when this was designed or built. My cred- I'm a toolmaker that runs Bridgeports (I even have two at home- yeah, I'm fucked in the head) and have had to fix them when they break.

Also keep in mind that chamfers on threads (especially coarse ones) will look like they are offset due to part of the thread being exposed, giving the illusion that the chamfer is shifted towards the opposite end of the exposed thread.

[@RJGMWR]

Not sure if someone mentioned it but yes it looks like you have an extended drawbar. Nice to have if using a right angle attachment or other attachment on the quill.

[@tylerwildman7119]

[@SgtStinger]

Doesn't look like the chamfers are offset to me, looks like the thread is tricking your eyes. Try putting a counter sunk screw in there to check. Also, dual rate springs only work if one of the rates bottom out before the end of travel, so in this application he could just replace the heavier spring with a longer delrin piece.

Your drawbar is the length needed for a right angle attachment. You have to run the quill down to clamp those on so a longer drawbar is needed so it can be tightened with the quill down.

[@max_archer]

It looks pretty obvious to me that the holes for the vertical rods were drilled out of place. That's why one of them is way too close to the edge, and why the socket isn't centered in the hole. Obviously the whole "frame" assembly still fits, so my guess would be that something went wrong with the fixture and the whole baseplate was out of place when they were drilled, or that it was a code error.

[@neliumAPG]

Preface -- AvE, I love your vidjeos! I know this is a 4 years old video, but I felt a comment was needed. The offset you were seeing on the chamfer of the threaded holes is due to the cut of the thread lead-in not being a concentric circle to the chamfer tool (i.e. spot drill). Threads will always appear to be off-center when they are actually perfect. Please keep the BOLTR series running, and your .. well .. you know .. in a vise!

John is a kick ass dude. Thanks for the up close and personal on this one.

[@WeTrudgeOn]

John went through several months of R&D on the drawbar puller, he talked to several other youtube machining gurus on the ones they were making or have made for advice/ideas on how to do it right. He went through several prototypes with bushings that tended to get uneven and get jammed when moving up and down. That's why he went to the recirculating ball bushings because they were longer and fixed the binding problem, the dual rate springs were all part of that fix. But I dunno, you can easily get two inch or three inch long bronze bushings that should do the same thing. John admits that ten yeas ago he didn't even know what a mill was, he's been traveling as long steep learning slope and one thing I can say without reservation, he is THE most impressive AutoCad wrangler I've ever seen anywhere, anytime, when he has a model he's working on he runs through commands and changes faster than a normal mortals eyes can move.

[@AtimatikArmy]

On the chamfer off centering you speak of, just thinking out load, but maybe it's centered and where the spiral thread randomly breaks through it makes it appear to be off centered? And the off centering of the Harbor Freight impact, that is probably unavoidable because you are bolting it up to the side of it's casting... (dimensions are going to float around from piece to piece).

[@shaung638]

I want a video on why the milton is the correct style of air tool connector.

[@453tye65e65e65e65]

In my experience the M (Milton) type air fitting is just the most common by far. I have know idea why but all the shops I have worked in use them.

[@DrFiero]

"M" style seems to come stock (installed, whatever) on almost all tools. I even worked for a tool importer (JET equipment) for 10 years, and never figured out why! They work, for most low flow things. But really, the best coupler I've used (for things with 1/4NPT ports in them) is the Milton "V" Hi-Flo. A mated pair (of V's) will out flow an "M" by (300%?). Bonus is that you can still stick your "M" fittings you already have into the "V" on your hose! With a loss of flow, of course.

[@shaung638]

Thats a good tip on the V coupler. Not sure what style of coupler I have around but I have been contemplating a replacement for a while now.

[@robbarchard]

I was going to right the same question, but knew if I scrolled down I'd find it! We are on Milton M, but I find we get product with A type pre-installed half the time. I used to save the fittings, but now we get em' gone so as to not dick around later.

As usual, good vid mate. Edit: Oh man, I have a feeling a machine did it. We use to do it by going side to side while descending. Yeah fuck me I'm sure of it now!... I should have watched more than the first few minutes.

[@Mr_Everyman]

I could be wrong here, but I think the butterfly impact is slightly off center due to the shape of the rear section of the tool itself being fixed to a perfectly flat surface but not being perfectly flat itself, you can clearly see the uneven Gap around the mating area and after it has been removed and sealed again it is even less accurate at being flat. glad to see that the screw holes have enough movement to adjust it, that was some good forward thinking.

[@rafaellastracom6411]

You are correct regarding the fasteners and furniture. It must be as simple as possible, using existing forces within the design. Packaging is very important. It´s about efficiency.

[@calvindekoter2128]

About the chamfers, perhaps they are uneven because the thread is present on one side of the hole and not the other- the hole appears to be off its own centerline because of the missing top thread.
