Large V-Blocks Modified for the Flex CNC

Today we're finishing the machine work to adapt some custom made v-blocks for use on the Flex CNC machine bed. We'll setup and use our KBC Tools milling machine to finish out the drilling work required to align the v-blocks to the fixture plates.

Maybe rotate one of the V blocks 180 degrees to see if that .003 difference improves?

[@putteslaintxtbks5166]

Just what I was going to say. Now I'll just tell you that good minds think alike, (sometimes 😂😮anyway).

[@johnschneider3082]

I was going to suggest the same thing.

[@Bob_Adkins]

I was going to suggest putting a piece of precision shafting in the V-blocks and sweeping it with an indicator.

[@theessexhunter1305]

I would have clocked them up with the long round bar then fixed them down, that way they would have centred themselves, the way it is know then the error shows up.

[@emilgabor88]

Just 3D mill it whit a ball mill to make them perfect .

[@orvillevoyles9451]

You might start putting a note inside the case of the tools that are gifted to you for a reminder, tools that have been given to me are among my most favorite

[@ostie01]

I know it's easy to say but, instead of drilling in the center of the V-block and dill and tap the shaft to find the center, I would have just used a machinist jack on the milling table to keep the shaft in the middle to find the center, but it's just me. Nice work, Jeff

[@OfficeLinebacker-FJB]

I do like your new fancy shop. However, I enjoy your old shop best.

[@williegillie5712]

Boy don’t ya love when the precision reams and pins fit so good the slowly drop into place on their own. You make it look easy Adam

[@BrooksMoses]

Yup. I've got a Sonnen honing "sample" fiddletoy that is basically just that. I reckon they knew their target market.

[@johnlee8231]

Its way close enough for most every kind of job we'd all do but I would still have to mess with it to try to make it closer. Thx for posting always enjoy the content.

[@h276wah7]

Now it's Saturday, thanks man

[@henksnijders3541]

Just perfect! So nice to watch!

[@angelramos-2005]

Quality work,Adam.Let´s use them.Thank you.

[@ronnydowdy7432]

❤ You did a great job lining up the dowel pins. Enjoyed the show very much.

[@jughead8988]

That 5 thousands dip in the middle is exactly why I never wanted to do this kind of work! My OCD wouldn't let me leave it that way and I'd end up chasing zero's all over the rest of the tool!

[@danielnorman8595]

You might just flipping one of them end for end. Either on the registration pins you made or just the entire thing on the rails of the C NC You might get those zeros you were looking for

[@karlbeckmann8865]

You can go at it with a ball end mill and use fusion to post a z ramping path Will have a long machining time but surface and precision will be worth it

[@user-nc9sh4qu3z]

What an amazing display of precision!! When you combine quality machinery with an expert machinist you get a level of accuracy beyond what you think is possible. Informative and thoroughly enjoyable!

[@stevecarpenter98]

I enjoy watching your videos.

[@0.c.979]

showing off when the pins slide in.. perfect!

[@clarenceburton9654]

From an old retired tool & die maker i really love your work and ideas , thanks for sharing your knowledge !! 😎👍🔩⚙️🛠️

[@brettbuck7362]

BTW, it is possible when pushing or driving the slip-fit pins in the hole, with a lot of oil around, for it to diesel and fling the pins back out. Have to push pretty hard, hit it with a hammer and you may get a surprise!

[@trace12345678900]

Surface a new V on them so they’re perfect to the machine. Would make a good learning project too.

[@ricksosbee3913]

Great video. Chips throughout.

[@kenshoemaker]

Would a machinist's jack under the cylinder pushing it upward into the Vee have located the center of the Vee without having to drill the V-Block?

[@tsmartin]

That's what I would have done. Seems like he made more work for himself for no reason.

[@yelims20]

or used a big kant twist clamp

[@jonyoungren3251]

Your stock left on that ream was correct, but your math was wrong. Typically with reamers, your pre-drill should be 2-3% smaller than the final ream size. For a .500 reamer, that's .010"-.015".

[@mikedyson7330]

VERY NICE WORK ADAM.

more hole drilling!!!!! I just can't get enough

[@mrgunn2726]

Thanks Abom, fun video. I saw that anti-sieze and thought; ughh, like honey, that stuff gets everywhere.

[@gertkristensen6451]

good job adam . you can mill the V block with a ball end mill if you want it parallel to the machine and then mill reference surfaces on the outside of the V block. so it's quick to find center Next time or use Haimer 3D in the V track to find center 👍👍👍👍👍👍

[@michaellee6168]

Black oxide coating on those V blocks would look good.

[@stevenslater2669]

Especially in the high-humidity in the Florida panhandle!

[@brandenoconnor7299]

Well done!! We work in metric, so the V blocks are only off by +-0.1mm. Thats more than accurate enough for larger jobs with larger tolerances! Great job Abomb!!👍👍

[@wayne4529]

Try spinning one of the V blocks around if they were machined as a pair they were cut clamped together so sides will match.

[@DonOblivious]

Ohhhhh that is some good reamer action. I'm glad I didn't have to open IG.

[@unclespicey42]

You can re-cut in place if you need more precision

[@ratdude747]

Posted (and deleted) the same thing. Similar idea as truing surface grinder bed/chuck with the grinder itself.

[@liamkelly8684]

And how would he do that with a fixed spindle???

[@ratdude747]

@@liamkelly8684 It's a CNC... interpolation. Move two axes at once.

[@unclespicey42]

@@liamkelly8684 could go it with a cutter ground to the correct angle and stepping up and down on two axes

[@brianschein2320]

I don't know anything about fusion, I've been a mastercam guy for the last 20 years if it were me I would just run a flow line finish .003 step over and resurface the V blocks so they were parallel to each other. They have the big cut out in the bottom so it looks like there's plenty of room to get a 1/2" ball mill in there.

[@TedRoza]

G'day Adam. The overall job worked out with slight variant off centre, which can be compensated through programming. The problem being that the larger diameter shafts will have a few thousands of an inch variants depending on the length, but even these will have to be trammed in before machining. So looking at your efforts, it looks good. 🎉🎉🎉

[@SteveInFLALand1]

Adam, I appreciate your content. Can you talk more about the anti-rust soak at your house? What are the materials and the process? Thanks!

[@JohnSmith-vi5pz]

Evaporust. Adam has done some videos on it a while ago at the home shop. It's just a liquid that you tip stuff in. My guess is that it's basically phosphoric acid.

[@francisschweitzer8431]

Paint…. Naaa. I’d go get a gun bluing kit and do the side faces. Would love to see you set up and run multi station on the Flex CNC … along with long pieces… that’s what the Flex is made for.

[@arlynsmith9196]

It is wonderful to see you back on the manual machine! CNC is OK but hard for me to imagine ever doing anything like that myself. But I treasure the instruction, tips, and ideas on the manual machines. I have missed them.

[@jimbarchuk]

For the year end highlight reel. 32:15 The fall time is *12 seconds* from :20 to :32.

[@alexkart9239]

you could mill them in place to get a perfect alignment

[@terminalpsychosis8022]

This is kinda simple, I mean, basically a V-Block, but all upside down n stuff, looks really crazy. It's almost kinda artistic, as much of machine work is. he concentric on that V set is so close to perfect... Lock anything in there and bump or shim it around. You got some wiggle room below too. That's a HEFTY set of Vblocks. Paint would be interesting, or blue them.

[@kevinbanham4900]

Great work Adam your work and precision is second to none it is so perfect if your hands were too warm and you held the pin for too long they would not fit. Great work keep it up.

[@tsmartin]

You went through the trouble of making that "centering plug" you should have used it as your datum surface instead of the flame cut edge. That would have insured that you were 90 degrees to the "V". It could also be used to measure the distance from center line of the "V" to the mounting surface and make any corrections if there was a difference between the 2 blocks by milling them. No shims needed. In the end you probably wouldn't have that .003" difference. At least that's how I would have done it.

[@howardtoob]

Great tip 10%

[@scottjones7279]

I am ordering a hook rule right 😊

[@JamesJohnson-cn1pf]

I remember you going to scraping classes, you could straighten them up in place and make another video as a bonus Just a thought

[@patrickspencer4360]

I was happy to see non cnc work, I enjoy that type of work. I do have one question, you used a precision equipment base to pound in the v-blocks. Am I over thinking this? Enjoy watching Patrick

[@AllenCavedo]

Shims, yes, or mill elongated pin holes in one V block and put a screw adjustable vernier on it.

[@timmieclark9976]

Could you use the blueing process, like gun barreis instead of painting them? Then you not adding thickness to the metal.

[@joewhitney4097]

Good Sunday morning Adam. Great video, you put a lot of hard work into fixturing the V blocks. As a hobbyist, I wonder if tapping with a soft face hammer the entire fixtures to correct the difference like you have demonstrated many times traming on the mill would have solved the misalignment or even slotting the holes for Y movement would help solve the issue? I guess it depends on how often the fixture is going to be used and its location on the rails. Heck, the temperature changes can probably change the outcome day to day depending how critical the tolerances are. As always, I enjoy your content very much and thanks for sharing.

[@stuartschaffner9744]

That was really nice. I wonder, wouldn't it have been easier to make certain your test cylinder was in fact a cylinder? I know that the surface was chrome plated, but I've seen you true up cylinders before in a lathe. Then you could have trammed the cylinder on the sides and on the top rather than measuring the bottom of the v block. One less step to introduce error. Thanks for explaining how easy it is to use shims if the workpiece isn't sitting right on the blocks.

[@michaelscansaroli9788]

Another place for diamond pins, check them out.

[@dennistennyson8856]

Adam, engine turning would look nice on the V blocks.

[@SupremeRuleroftheWorld]

32:15 for the money shot

[@lawriestewart6377]

Try rotating one of the V blocks and try to see if it improves or remains the same. You never know.

[@jonathanpersson1205]

How would those Vee blocks go if they were blued for rust protection?

[@user-bj9sy8gd4w]

👍👍👍

[@Maximusprimeatyahoo]

Rotate one of the V-Blocks because it may match up with the other side

[@cpcoark]

Check the back side of your V also. You may be able to turn one around to get a better alignment.

[@peterlee8982]

Great video. You need to put your logo on the v blocks. And maybe a date.😊

[@dennissheridan1550]

Adam, you could try flipping one or the other around and see if you get them a little closer to each other.

[@billspence1799]

Adam I think you said to allow 10% for the reamer. Should that have been 1%?

[@JohnSmith-vi5pz]

2 or 3%.

[@billdoodson4232]

Another precision job, that I could only dream of achieving. Not sure I would have hammered in the pins with the fixture on the mill bed though.

[@gigaherz_]

given it's supposed to be able to handle the forces of cnc machining, I would assume it didn't even feel the soft blow?

[@billdoodson4232]

​@@gigaherz_You are probably right. But I'd still have taken them to that nice Fireball welding table, situated them over one of the legs with some plywood or similar underneath before wacking them.

[@emilgabor88]

3 thou is for you precision job ?

[@inovator8603]

That was a nice wedding night fit on those reamed holes. ;)

[@HishamMosa-ie5fl]

@20:00 if you indicate the shaft at y axis ? Befor making holes, I love your videos thanks Adam.

[@Spronkadunk]

Couldn’t you just use the FlexCNC to machine them dead straight?

[@koford]

if you want these to be absolute perfect parallel, just machine them right there 45 degree each side and both are same to that setup / machine.

[@chrisarmstrong8198]

Maybe should have swept the other sides of the vees, too. The heights of the vees may be slightly different and the additional sweep would pick this up.

[@joeylawn36111]

32:30 😎

[@emilgabor88]

The best way to do this would have been just bolted down and 3D mill it whit a ball endmill. Adam , you’re a pretty smart guy, why did you do it this way it was so predictable that they won’t be in line because you accumulate a lot of errors and you work a lot , for a crappy result. Think like a CNC guy , 3D mill it

[@michaelscansaroli9788]

Look into diamond pins. One diamond pin and one dowel pin is a locating set

[@firesurfer]

Now I'm impressed! That's a nice fit. How much of a taper on those reamers? It can't be much.

[@emilgabor88]

Impressed about the 3 thou difference? The fit doesn’t matter if they are not in line

[@minigpracing3068]

Could you write a program to go through and recut the V to be more true? Also did you try lifting the assembly and moving it to see how repeatable they were?

[@denniss5512]

Ah, a Saturday with an Abom video, only made better by the Abom Machinst dowl pin fit. Was wondering if you would use the machine to true up the V.

[@richardandrews6754]

Hi Adam, did you try turning one block around? may line up better also you could finish machine as a matched pair in the Flex, could make another video. Stay safe you guys

[@adamgentry332]

Adam, i dont think you should have used the surface of the hot rolled plate to tram in and find the center. The v way may not be perfectly perpendicular to the surface you used as your reference. If you sweep the chrome rod, you pulled into the vally of the v, in x axis you could have verified it was perpendicular to the y axis dowel pins

[@user-ji9ws5zm4j]

Такие точные вещи нужно делать парой. А отверстия растачивать.

[@mfc4591]

Saturday night for me is now complete and I am going to get some sleep. Thanks forvthe video Adam

[@DontCallMeGarage]

Adam are you going to do a clean up pass on the v faces with the flex cnc to ensure they are exactly the same?

[@kevinsellsit5584]

Did you try turning one of the blocks around? I know it shouldn't change but it's worth a try?

[@davidwinokur2131]

Is it possible that reversing the orientation of one of the V Block assemblies will lead to better alignment?

[@guillo2388]

Sweet at 32:20/32:32 and 33:06/33:17

[@paul-g]

Would it be worth mounting those fixtures to the tiltable bed of the shaper and making those vblock faces true to each other?

[@davidmcduffie1398]

Adom, try rotating one of the V-Blocks 180 degrees and recheck with the indicator, it may or may not make them closer to each other ? ? ?

[@photon393]

i think if use the edgefider on the 45 degree face of the V block it will work as long as you dont change Z height from side to side, have you tried this?

[@photon393]

nevermind, I commented before realizing which side you were drilling from. I just needed to listen better in the beginning 🙂

[@turbocobra]

Bro, just say the word and I will bring my paint guns, and we can put a nice thin but durable catalyzed epoxy finish on those v blocks, and the vise

[@eastcoastwatch672]

I wouldn’t quite wrap up those “V” blocks yet. For ease and convenience I recommend you elongate the “T” nut holes on the “V” blocks fixture plates to be able to slide the “T” nut studs into the “V” block fixture plates like on the vices instead of trying to fish through the holes to thread the studs into the “T” nuts.👍

[@mikemanning998]

Man... it's a shame you can't mount those V- blocks in a CNC and machine them to perfectly match... huh? huh? hehehehe

[@thething4763]

Can you use the flex to machine the V blocks in place on the flex?

[@johnschneider3082]

Adam, a question if you don’t mind. If you use shims for alinement won’t that throw off your parallel end to end for height? You might be better off decking the one side of the “V” block the .003 “.

[@braddobson2060]

It would be nice if you had one channel for cnc and one for old school

[@firesurfer]

Maybe... but that would be a ton of extra work. Probably would have to hire extra people.

[@michaellee6168]

Don't forget the CRC 400 on the fixture plate before mounting the V block assembly.

[@ColinLennard]

Do you mind me asking - that table that you made those V blocks for - what are you going to use ut for? Thanks

[@geckoproductions4128]

Thanks for pro tip "leave 10% for the reamer." BTW: do you mix your own brown cutting oil? What's your recipe? (I also like Anchor Lube)
