2-4-6 BLOCK CORRECTIONS PART 1

[@paultanner88]

I just found your channel and you are a very interesting man with lots of knowledge and experience I really appreciate it keep up the good work my friend

[@paultanner2007]

I will learn a lot from from your videos

[@remodz6385]

Hey Stan, looks like we are missing a bit of grinding footage from about 24:00 to about 29:00 roughly. Great video, those blocks are usually pretty well squared. Mine have about the same measurements, except they were a little better on the faces. About .003-.004 out, but I always use them stacked on ends anyways. Thanks again!

[@arcanix51]

you've earned a subscribe. ... just because of how meticulous you are. i wish i had the tools you had for checking parallel and square. ... but in all the things you described and showed you are 100% correct.

[@killtune]

Hey Stan...there's about 5 min of "black" towards the end. From ~24:05 - 29:40..just wanted to let you know.

[@stirlingfromla]

Intermission....I made some popcorn...

[@ShadonHKW]

Wow, I totally blew that one, part 2 is mixed in there, but still not complete. I think we should re-upload and start over.

[@KK10155]

just edit the video and trim unwanted parts under the 'Enhancements' tab

[@ShadonHKW]

Trimmed it, first time using the you tube editor, worked great :)

[@sasicestates]

Hope you don't mind the question...real quick answer wanted. What are they used for?

[@khaledadams4329]

Trying to find out the proper bolt size and threading for these.

[@grahamokeeffe2196]

Thanks for sharing, If I'd seen this video a few weeks ago I would not have bought the 2-4-6 set from a local supplier that I just bought, same box, wrapping and etc. Made in china rubbish and after looking at mine they are being returned to seller. The thread is 5/8 x 11 and the clearence holes are 5/8" but should be 11/16" diameter, bolts won't go through holes. So with these you can't bolt them together as intended to use as a square. I'll make my own.

[@chrisstephens6673]

On your new 123 blocks, are they still coming out of China with clearance holes too small for the 3/8" bolts? If they are, a solid carbide end mill works wonders.

[@Keith_Ward]

I was wondering the same thing and couldn't quite tell from the video. I was hoping he would say.

[@asterix2419711]

Hey Stan "Red" hammer for final inspection, the "Blue" hammer is for rough inspection?

[@bcbloc02]

Not great but not bad on those blocks from the factory. It would be nice if they came more oversize so after you fixed them they were on size.

[@chrisstephens6673]

Except most buyers will not have a surface grinder, but for those who do you are bang on.

[@shotgunreloader4964]

Is it possible to drill out the through holes on 123 blocks so the screws have clearance like the 246 blocks you got? or to hard?

[@ShadonHKW]

Carbide should get through it :)

[@reideichner8597]

Nice fix on the blocks!

[@tubalcain1]

Did you mention where you got the blocks from? I probably missed it.

[@ShadonHKW]

All over e-bay, cant remember the seller.

[@RambozoClown]

When you measured the first one, I thought, cool, just enough material left to lap it to final size. But then my hopes were dashed once you checked the second one. Import is always a crap shoot. Never know what you will get. I was actually very surprised how good the first one was.

[@alexkern9134]

Looks like you got unlucky there on that block. I recently bought a pair and like you, found them very parallel and out of square. Mine were only out of square about 5 tenths though.

[@notsofresh8563]

You know, it wouldn't be to hard to make a plastic bushing for the hole in that granite square to attach "outriggers" that sit just above the surface plate , which should not effect measure but will stop the square from falling. Since those 246 blocks are both equally oversize in all directions do you think they were ground in china in an unheated shop and the oversize is due to your shop temp?......of course there is the square part..

[@ShadonHKW]

Good thought on the big square, sure would hate to lose that thing.

[@marceltimmers1290]

Hi mate. I would like to know what those blocks cost. If the price was very good, some remedial grinding would be Ok. However, you indicated that those blocks were not cheap, so are they worth the investment? Oh by the way, thanks for giving me the time to make me some coffee and read Tolstoi's War and peace during the iter Metso. ( O;

[@turningpoint6643]

1" X 2" X 3"= 6 cubic inches verses 2" x 4" x 6" = 48 cubic inches. So 8 times more material. Then larger holes are drilled and tapped, and then all that extra surface area for surface grinding to get done. Depends on your wallet, but for me even the import 246 blocks were not exactly a give them away price.. For what they are and the use I get out of them they were pretty cheap.Suburban Tools list a pair at $600 and within 3/10ths accuracy per inch? or over the full block I don't know. My guess it's over the full block. Grizzly tools about $105 and within 3/10ths per inch. There likely better than that, but they could be out by .0018 on the 6" dimension and still fall within specification. Suburban list a pair of 123's as weighing 3 lbs. A pair of 246's as 24 lbs. There is a huge difference as Stan mentioned between the little one's we normally use and the big ones. For me I think the larger ones are more useful as set up blocks, squares, and even checking other parts for squareness. Only you can judge if the higher cost is worth it I think. But like he also pointed out, any shop reference standard does need to be tested before you can be positive it can be relied on to be an accurate reference.And at least for me, there ultimate squareness is much more important than them being to an exact nominal size. Simple math adjusts for any size difference if that's needed. It would be a pita to shim every time to get a square surface.

[@marceltimmers1290]

Hi mate. You are quite right mate, the end user determines the quality of the the product. I would think however, that the blocks being the same dimension would be a must. I would not want to think of having to take in account a discrepancy every time I wanted to set up a project.

[@ShadonHKW]

Hey Marcel, I totally spaced the edit on that one, uploading the corrected version now :)

[@11zekim]

Good save, a great opportunity to teach toolmaking. But consider: these were (presumably) WAAAAYY out of spec. Maker, importer and dealer all got paid in full for zero QA. This rewards them, and penalizes their competition who choose to give a crap. With rare exceptions (like maybe, making an example video!), everyone should stand up and return junk that doesn't measure up, imported or not. Otherwise, quality tools will go extinct; no reason to make any.

[@ShadonHKW]

All good points :) When these came in, I almost returned them, but thought it would make a good video to show you guys.

[@jasonburns1407]

The mush hammer would have come in handy stan:)

[@paultanner2007]

Thank you
