Description: First I want to say that all of the schedule delays in this video are 100% my fault. To film all of this during finals and back to school, it was me who couldn't take a full week in a row off of work and knock this out. Never order the wrong part before Christmas and New Years and expect shipping to ever work right. This was a big job and Ballos Precision Machine in Richmond, VA did a great job not only with my parts, but with their patience in putting up with my busy work schedule so they could fit me in to film every step of this. That has to be really annoying and they never showed it. In Block Prep 7 it was discovered that the piston to cylinder wall clearance was inadequate, and that there were uneven oil clearances and taper on the mains. If you're new to engine building, the main journals are the most central part of your engine. They support the bearing and hold up the crankshaft which every single function of the engine is connected to. As seen in the video, the cylinder bores are easy enough to correct. If the crank journal diameters aren't consistent, if you're using a bearing girdle, if you've had to machine the block from a previous failure or there are casting defects, then this process can be fairly tedious. In this video I got permission to actually work on my parts and experience the entire process, and some of the difficulties a machinist might face doing a job like this. If you detect any frustration, it has nothing to do with the people, the parts, or the machinery... it's only my expectations falling apart. Not every job will walk in and out of a service provider's facilities easily, and mine was no exception. This job would have taken a machinist more than a week to complete, and that's once it's moved to the front burner. Any frustration you might detect was created by ME aligning my day job schedule around all the work that my block ended up needing to be right. I didn't think it would be that bad? Anyone's job could have clustered like this. That was a priceless lesson for me to learn. I chose Ballos Precision Machine because I've successfully built 4 engines and completed countless other fixes over the past 20 years. They've always proven themselves capable, competent, and straight-forward with setting my expectations. You will see that demonstrated here very well. They've done all of the machining on the parts you've seen in all of my videos, and I've won trophies with their work. Though their heritage is auto racing, they already service everything-and-everyone who has precision machining needs. Automotive, aircraft, marine, manufacturing, and the medical community to name a few. They're always busy, and it's a gift that I got to do this at all. Also grateful to my employer for being so flexible, generous and patient regarding the use of my leave balance. I used it all for science! Hopefully this video serves as an example of what to expect if you ever have to go through this process. Hopefully it shows what you might not get to see happen if you hire someone to do this for you. Know that machinists face tedious jobs like mine *all the time* and it could happen before, during, or after your equipment ends up in the machine. This is why patience and acceptance is so important. Not just for the machinists... but for the customers who are asking them to perform specific and precision miracles. A machinist's job can be repetitive and sometimes thankless, but I know my viewers aren't the people who contribute to that. I know my subscribers all love and appreciate the people who help them achieve their dreams. Make sure you let those people know you're grateful when they lend a hand. I could not have completed this job or brought you this video without the great people at Ballos Machine. If you want to support my production, please visit patreon.com/Jafromobile.
