checking our work...is it really square?

In this episode we confirm that our bhj fixture is accurate.

@@JonBanquer I didn't forget. I was talking basics. Besides, sometimes that's not a desirable thing.

I would say that you are doing a Top Notch Job Daniel. What we all were trying to do is get the decks at 45° So we can get the cylinders at 90° to the deck. Even .002 to .004 is seconds of a degree. So much closer than the factory is. When you look at the variances of the pan rail, main registers, china wall and decks. Most likely machine in different machining stations and each station and or opperation has it's own tolerances. I would say you are absolutely spot on. Remember, you are on the business end of things. Thats the part that makes the Horsepower. Nice work. 👍👍💯🇺🇸 Thanks for sharing.

[@powellmachineinc3179]

Absolutely 💯

I watch your videos at work when I'm not busy with a customer. I work at AutoZone and was a automotive mechanic for almost 35+ years. I've worked in a automotive machine shop. Your videos are very educational and I share them with my boss and coworkers so maybe they have a clue what it's all about. Thanks for the great videos keep up the good work

Ty! We really appreciate that 🙏

If I was close I know exactly who would do all my machine work! I went to school for machine tooling and did a little prototype , tool and die , and job shop machining for 12 years. Miss it but had to take over the family farm. But I love watching someone who knows what they are doing! Keep up the good work and the videos!

Get on machine probing with a Renishaw probe. This way corrections can be made immediately. With a CMM you have to return the block to the CNC for rework after checking if the block needs rework.

[@powellmachineinc3179]

This machine is manual, you can't use a probe, my big cnc mill when I get it set up for block machining we will do the blocks in it, but regardless, we valided our fixture, so we don't need to do it again.

[@JonBanquer]

@@powellmachineinc3179 Most of the industry has moved to on machine probing because it's invaluable.

I like seeing that Driven shirt and banner up in the shop 👀. For some reason I hadn't noticed that before, but unless I've missed it (which is certainly possible) do you have some thoughts for a video on oil for your builds and break in oil? I've seen what you use during assembly and what not and I feel like everyone likes Drivens BR oil but I don't recall hearing your thoughts on oil specifically too often. That is, at least in the way I'm thinking, I know obviously you've covered and explained plenty of oil dependent systems. I remember during the flat tappet transition I saw some videos where you mentioned oil viscosity playing a role in eating up distributor gears on cams, but I'd be interested to hear your thoughts on types, additives, viscosity, or whatever you'd be willing to share. I also understand if that's something you're not as interested in since its a bit of a can of worms and you can just recommend a variety of products based on clearances and application and the customer can choose whatever within reason or figure it out themselves. Love your videos and I like that you guys do periodic checks of your equipment to try and verify and validate your system.

[@powellmachineinc3179]

We will talk about that on a video

[@johngatsby1473]

So how much would it cost if someone brought you an iron block ls2 (whatever they're called) that was previously built with all forged internals and i gave you the bare block and said to make sure all if this was done. You set it up and found that all was done and in great shape. What would that verification cost? And if it needed to be squared up, what would that cost? General cost is fine, i wont hold it to you

[@powellmachineinc3179]

prob 3-500 to check everything, if it all needed redoing, maybe 700-1000

Question: I'd like to break into the industry, I went from IT/Software Dev to becoming addicted to classic vehicle restoration specifically the BMW e46. I quit my job and have been working as a mechanic to make sure I had the necessary skills, now its time to get into the machine side but my financial reality is I can't maintain my bills for less than 30/hr. Am I a lost cause or is there a place for me? Thanks.

@@powellmachineinc3179 Unless people are starting the trade out of high school or they have savings to support themselves I don't see how it's sustainable. I've watched other videos of yours talking about the difficulty finding new workers. With rents and basic expenses being what they are I just don't see how this is sustainable. Or you would have to work two jobs. A potential solution might be guaranteed bumps in pay over specific periods of time if someone proves themselves? I don't know it's a difficult time and inflation continues to raise costs of everything.

The main parting line is irrelevant.

[@bobhudson6659]

So the main bearing parting line alignment bears no relevance to the accuracy of the motor? Please tell me (and all the others watching) what is your background that allows you to say that.

[@optimumperformance6998]

​@bobhudson6659 it is, the caps sit in their registers, as long as the main line bore is straight, parallel to the cam, bores and decks square to that reference, a parting line is just a parting line. Unless you have 2 deck plates torqued, main caps torqued to introduce all the stress into the block and have probing holes drilled into each cap you are not really measuring anything. The goal is to make it as square as practical and everything moves once you bolt things to it. A relaxed block is not how the engine operates. If you installed torque plates to both banks the pan rail sweep would likely change. Cross bolted mains change all of these dimensions. There is a point when all of that becomes an impractical rabbit hole.
