I have 20 years in the machine shop as a Journeyman Machinist and Class A Tool & Die Maker. I have spent many hours on a surface grinder, grinding things parallel and flat. I found that if you have two surfaces that are warped, I have gotten Plaster of Paris and mixed it pretty thin and poured it on the bed of the surface grinder, then put the part on top of the P of P and worked it in until the high places touched the bed then set back and let the P of P dry completely, then turn on the magnet and surface grind the top of the part flat. The P of P would fill in the high spots from the bottom and when it dried and I turned on the magnet, it didn't move. Then release the magnate, remove the part and clean off all the P of P and lay the ground surface on the bed and grind the other surface parallel. I have found that 99 times out of a 100, this worked to perfection.

Great method!

I actually worked at the KURT vise plant in the 90's, making D60 vises. The level of quality control was ridiculous. We were actually sent home for days because the castings wouldn't pass the test you showed (under MUCH higher torque) until the foundry figured it out. Even though it was a tough job, it's still the only vise I'll ever use. Money well spent.

As a home shop DIYer who never does anything commercial and doesn't sell anything to anyone, it's the difference between having a tool and not having a tool. I would LOVE to have a KURT vise. But since my tools don't pay for themselves, I can't justify it.

Grinding the vise will not reduce the amount the part rises during clamping, but adjusting the angle lock feature will...

Eric Jensen The thing I like about Ave, other than the humour, is that he exposes the marketing wank for what it is. He hooks up instrumentation and shows you the true specs and how they differ from what's on the box. That is useful information for a consumer. And sometimes he finds out that stuff really is good, like the fluke multimeter made for the chinese market at 1/4 the price of the ones for sale in north america. I have no issue with being negative in a review if it is honest. When you start accepting freebees, which he doesn't do, it really muddies the water. It is a slippery slope. Eventually you will find yourself in a position where you have to put a positive spin on something questionable. You don't need freebees. Don't do it.

Dale. Another thing with castings is ageing. They really need throwing out in the yard to rust and get hot and cold for about a Year before final machining. That is why if you can get hold of old machine tools, they are great not only because of the original ageing before being machined, but also the further ageing over the Years. A bit like Scotch Whisky, the older the better it gets.

Hi Valkman Thanks for subscribing :-)

Great work. I’m not sure witch part I liked the most “ the trying to make a good vice for a bad vice “ or “ fixing all the bad grinding “ thinks for sharing.

Out of curiousity, was anything inspected or corrected with the underside of the screw contact? I know that I own a couple of chinese vises and some were very low quality and others were astonishingly great. most of the bad ones were difficult to get fixed up and within usable spec for anything requiring tight tolerances, but big improvements were possible. the lifting issue was one i corrected by cleaning up the underside of the saddle where the bottom plate rides and cleaning up the pull down mechanism when clamping force is applied. i did not use anything scientific except a dial indicator in the spindle for before and after clamping rise results, but i was able to reduce it to about .0015" under my regular clamping force where initially is was .005-.006". wasn't sure if you wanted to correct that any since you already put in the time to regrind everything flat?

Great video, Dale! I see you are making good use of your new metrology center. A poor quality vise will hold stuff, but that's about it. My experience working with cheap vises is one of working around the lack of consistent parallel / perpendicular surfaces. It can be done, but requires a lot of thought, and a lot of checking and rechecking before making any cuts.

Now this is what I wanted to see. I knew that the Kurt and the knockoff weren't the same, but could it be made the same? The answer you provided made sense with the casting problem. I enjoy the comparisons, and the solutions to any problems as well as the WHY factor.

I've been machining in a hobby capacity for a decade now and I still don't think I'm done drilling divots in my Chinese vise. I made yet another one just the other day. I tell myself it improves the aerodynamics.

Awesome...you gave it every chance (other than maybe stress releasing it before the re-grind) to work, or even improve a little...subscribed!

I visited a US tool maker many years ago. They put the castings outside for 1-2 years before they machined them.

Good demonstration on the economy of built in value.

Interesting videos in that they quantified the expected differences. I think the Chinese vice would work well for 95% of home machinists. When I was a toolmaker things were milled to a few thousands tolerance and anything required finer went on to be ground. I do wonder if the inaccuracies would be noticed by home machinists. The Chinese vice is appropriate for people with mini mills. I don't see a lot of sense in investing in a vice that cost two thirds the price of the milling machine. In a commercial workshop things are different and budgets are bigger. A good test would be a test piece from each vice milled on the same milling machine. Say a block milled to 4 x 6 x 2 inches

Ha! I've got that exact same chinese vise, with a turntable. Was about 15 years ago, I was a machining newb (still am, I suppose), I didn't have a surface grinder, but did have a new to me Bridgeport (1958 M-head) so I took the vise apart, flipped the body over and milled the base, then squared it out from there. I still have it, and it occasionally gets used. Was a pretty good beginner project.

Great video. You are really good at explaining what you'r doing.

Well said. I bought a CCVice it was all my budget would stretch to. It will get me some experience with my new milling machine where at first ,exceptional accuracy wont be an issue.

So just to add to the fray, I took my old style bridgeport vise. Original BP , and with a tenths indicator did the same test. I am out .0017, so that's better than the knockoff. And this does not have anti lift design. So I am happy, I think I am in an acceptable range right now for my needs.

No safety glasses touching off a running grinder at 7:40, BRUTAL... you would be fired on the spot at my shop.

Hey I have the same vice and thought about getting a more expensive vice but as a tool and die maker thought about fixing it with what i know. if you re-machine the key way to a tighter tolerance and drop in a 3/4 key. then get new bolts and put about 120lbs of tork on them. That will fix the vice and stop the solid jaw from moving because there was too much clerence in the key way.

When cast iron cools unevenly or too quickly it will crack. Their problem has to to be that they’re timing the cool down period to the bare minimum to speed production but causes as you mentioned, post production warpage.

I agree with your point that the comparison is fair and your reasons behind that. My extremely low budget shop stretched just buying the cheap Chinese vise, and even though my measurements pretty much agreed with yours it was a serious upgrade in my work holding. For me the cheap stuff makes sense. For any serious or professional machine shop it would be a hard no.

keep on doing your reviews, you're doing great. i work with after market parts in the auto industry and i can tell you i'm tired of re engineering parts to make them fit like U.S. made parts, so, imo you're on the mark. oh by the way, took your advise and am building something cool (light sabers).

This is exactly why I saved up for a Yost vise, instead of being tempted with Harbor Freight coupons. The differences between USA made 65,000 psi ductile iron vs 10k gray iron is night and day. "Cheese Grade" is a perfect analogy. My HF vise literally failed like a block of cheese does when applying pressure. Just because something is heavy or made of this steel or this iron... does not mean they are the same. Or if the companies care about cost saving vs. quality at any price. It's up to us the consumer to learn about the subtle differences and nuances that go into manufacturing and cost-balance-ratios. Because the companies that are in business to get your money certainly know all the details.

Excellent!

I like this video more than the last because its not really bashing the vise but you are making comparison of quality, still it was a cheap shot at AvE, he has shown that even the most expensive tools make compromises, that some cheaper tools are worth it but more importantly that it takes someone taking it apart and seeing how its made to see which companies make the best compromises for the $$$, like he said he is partial to Snap-On but its not the best bang for the buck, and I love that now I know Makita engineers know where to use what components and what processes to make a high quality yet affordable tool. Keep up the good work.

One of the ways that Kurt keeps the moveable jaw from kicking up under load is by putting a couple of o-rings below it to give it some spring. This allows the ball mechanism (ang-lock, their main patent) to pull the jaw down and pull the part *down*, not up. One of the main ways the imports cheap out is by skipping something like that. You could have removed more of the part lift by cutting the mounts for a set of o-rings into that jaw. Maybe 20 minutes of time on the mill to use a 1/2" center cutting end mill and maybe $0.10 worth of o-rings straight from Kurt. It's all well and good to point out that it costs time and money to make that vise better than it came from the factory, but there's working smarter, not harder too.

I personally like seeing new cool products. If I already didn't have 2 Kurt 688's I'd seriously consider that vice.

That’s a pretty good comparison!! You sold me on the American vice! With your grinder, you can pull the handle of the chuck to halfway and it will still hold a large piece but won’t distort it as much. It’s not as good as a variable magnet but it helps.

when grinding the base shimming is needed if the part rocks but this part weighs enough that the magnet is not needed when taking light grinding cuts . I also prefer a electro magnetic chuck when grinding it allows mag force to be adjusted just enough to hold the part down without distorting your part

ahh forgot to ask how did you fit that imperial toque wrench to a metric vice as that was a big problem for you in the fist video

Question: When setting the indicator on a round square, how do you know when the point of contact of the indicator is perfectly above the point of contact with the base?.. Do the two points automatically fall in line? (I've always used the two opposing sides of a parallel to do this.)

@robertvanstaalduinen7245

6 жыл бұрын

franksalterego i think because the indicator base has a curve it is directly above the curve somewhere and by rolling it around the curve you find the highest reading... setting that to zero

Great info!

The deflection of the block depends on the pressure of its two sides. The torque is just the same on their screws. In order to measure the TRUE difference between them, the difference between the screws in the two vises may be needed.

Brilliant.

As a newbie hobby machinist I found this video really interesting. I have a Chinese vice and suffer from not being able to tram it in as it's all about averages rather than accuracy, however my lack of skill matches the quality of the vice. Anyway, I have often thought about trying to machine out the inaccuracies, but after this video, clearly it's a waste of time. Whilst it's a 'get what you pay for', I couldn't justify the high costs of a decent vice, but a machine shop would. As with any interests, you upgrade as your skills improve.

Thanks for your comment Terry. I was a newbie once too, and still feel like one today. But as your skills grow you will need better equipment, and there is no better reason to get a new machine and tooling then your skills have out grown the old ones. :-))))

stumbled on this channel, subbed!

It would be nice to see the results with vices bolted to a stout machine table.

There are some things that I don't mind having cheap tools. However, when I need constancy, repeatability and accuracy and where I am using a tool frequently it is worth spending $$$>

I just found your channel... subscribed! 😁

I’m glad I bought a Kurt DX6 for my home hobby shop.
