What are the symbols and letters popping up throughout the video?

One good machinist is worth more than all the congressman in Washington

I restore a lot of tractors and I sure wish I was a better machinist. The machinists around me don’t like to work on anything they can’t just put in the CNC with preset values. The ones who will are getting older and retiring. Glad to see a young feller such as yourself learning and more than likely taking over the family business. Great work as always. I’m glad my son showed me a Tik Tok y’all made which brought me to your KZfaq channel.

Your old man has some great knowledge stashed away in that brain of his. It's also great to see the younger generation taking interest in a trade that runs in their family. My family is all welders except me. I had to be the black sheep and be a heavy mechanic. I'm still invited to Christmas though, lol.

I've never heard of a machinist that actually took the time to clean up the chips as they go, let alone prevent them from flying all over creation. kudos, my man.

Love seeing all the Sunnen equipment. My grandpa worked for them for over 35 years, I guess he was right saying they're the best on the market

I'm glad you popped up into my stream two weeks ago. One of the best channels on KZfaq.

Great Vidio, great to see your dad and you working together. I have learned a lot watching the two of you. Thanks Cliff

I'm a 76 year old guy and retired pilot. I have never had an interest in the sort of engineering you do, BUT I have to say, I'm totally fascinated by what you and I look forward to each video. In fact I go looking for the old videos to feed my new habit. Thanks for sharing your passion.......

Excluding a few of the Christian videos I watch, yours are the best I've seen. Not only are your machining skills outstanding, but your presentation is fantastic. I always watchi all of your videos to the end. Thank you for taking the time.

I'm Shure the precision machining has greatly improved since that block was first manufactured. That should be a much finer engine block than the factory ever produced.

Nice! People don't realize the amount of work it take to make something better than original!

My new favorite channel on KZfaq for sure

When my dad was a dealer they still made new parts for those back in the 80's. We ordered an block for A back then.

Great job ! I am impress on how much care you are both taking in doing your work. I would not hesitate one minute in bringing an engine to your shop for rebuilding. On the other hand I was a bit surprise when I saw you drill the spark plug and decompressor holes by hand. I am used of seeing you taking so much care. I know a set-up on a press drill would have taken time but it would have maybe reduce your stress and reduce the risk on damaging the block. For the spark plug holes a drilling sleeve with OD fitting the thread and ID fitting your need would have helped you with the alignment and protected the threads… Anyway I understand this was a unique job again and noway I could have done better the entire job. Well done and thanks for sharing!

"No energy system can produce sum useful energy in excess of the total energy put into constructing it. This universal truth applies to all energy systems. Energy, like time, flows from past to future". Thank You Jim et al, amazing videos indeed.

I had my JD A block bored to 5 5/8". The first shop screwed up the cylinder and put a sleeve in. It came loose and went in to the crank case. The second shop rebored for a larger sleeve. This shop pined the sleeve to the block in three places at the bottom of the bore. All is fine now after twenty years of pulling! I also use candle wax to lubricate bolts when removing them from casings. The bolt should be cool enough not to light the wax and hot enough to have the wax run like water. Penetrates very well. Patience, patience, patience! Great videos..

Great video! Love watching these old JD blocks get rebuilt. The relief valves underneath are called Petcock’s there a decomposition valve so there easier to start by hand. Had a friend build a costume block from well casing to build a stroker motor in there JD G, they were 9” Caterpillar Pistons when they were done. Also a quick hack we used for drilling the plug hold in the repair sleeves was use a broken spark plug as a guide. Just my two cents. Anyway again great video. Keep up the good work. Be well my friend.

Beautiful work!! From someone who started rebuilding engines in a machine shop before he was 18 years old. I got to work with one of the first two Sunnen Ck10 machines in California in 1970 at Merced Junior College. Man how the equipment has improved in the last 50+ years!!

I was a corporate store manager for the only NAPA Auto Parts in Portland OR with a machine shop. All I know is the market that I managed, and DAMN was it hard to gain business to keep the shop alive. I had two phenomenal machinists too! Both of them with over 30 years experience, and I never had issues with them or the work they put out. Customers loved em too! Congrats for you and your pops being able to keep the doors open & hopefully thriving. Good idea starting KZfaq- the additional revenue might be what keeps you guys afloat one day, who knows! 😀 I'll keep my eyes peeled for new uploads! Glad to see y'all in the space!

Something I found useful is from K&S Precision Metals. It is a brass tubing found at most hobby shops and hardware stores. Each size of tubing will fit over or inside of the next size tube. I use this tube when I need to drill out broken bolts or holes as you did in sleeves and other things. I place the size tube that fits inside of the hole with the broken bolt. If necessary I can use a few more tubes inside that tube and than a drill bit inside of those. The tubing keeps the drill bit centered while drilling a hole in the bolt. This is very useful when trying to protect threads from a spinning drill bit. Hope this helps.

17:50 That satisfying moment when the broken stud starts to move after a lot of work 👍

Love your videos man, your very humble and can appreciate a father teaching his son a trade, keep up the good work..I’m subscribed and will probably watch all your videos and will be giving a bunch of thumbs up

I am totally amazed by what can do on this old stuff. Looks great

In my 30+ years of working on aircraft, I have picked up (drilling a hole from an existing part into a new part) thousands of holes. Usually in expensive parts. A safer way of drilling the spark plug and compression release holes without damaging the threads would be to make a drill bushing. That way, you can drill the pilot hole at the exact angle. Then drill the holes to size using piloted core drills. Works every time. Less chance of "we messed up".

I wish we had such good skilled workers and machines here in Pakistan for getting our blocks and heads machined and configured new. Great work and great videos

Better than new perfection that’s what makes repeat customers

I feel like the process and results here are far better than factory.

I really like this video. My Daddy had a Poppin Johnny from 1946 till 1950. I love that sound.

got to say i tried a long cylinder bore and didn't fair to well for me hats off to you and your dad, you guy's display good machining habits you don't see in the world of automotive machining anymore.

The two holes you drilled are for petcocks to release compression to ease starting when hand cranking engine. Early John Deere’s were hand cranked turning flywheel by hand. Excellent workmanship.

I just started watching you guy's a short while ago. Awesome content, awesome tools, awesome craftsmanship.

I love watching stuff like this!

Love watching these video's. You and your Dad do great work.

massive respect to you and your father for the great work that you put into the machine work

Looks better than new!

This is great to see you n father working together .Keep up the good work.

Your not just a machinist.....your an artist !!!

It's great to see that at your place that quality and pride are still number 1.

Stellar job/explanation/videoing!!

Great video. (Like always). Thanks for taking the time to show us your skills...

To add on one of the previous comments... That is one of the cleanest shops I've ever seen!! ... Love the videos

Outstanding work!

In 2014 I bought a JD X300 to do my lawn, I love it! I wish i had bought it years before that.

Good job! That’s my favorite tractor. I just love that sound they make. I only operated the hand start ones too. Thanks Ron

Wow! Incredible machines! Very exacting work. Nice job!👍

Very nice work hats off too your dad for the fine hone job looks like a work of art

Great segment

You dads a cool guy gather his knowledge while you can, love your content

I love watching videos like this. This would be my dream job

Lookin' GOOD!!!!

Splendid machine work

I’d love to see this motor running and pulling. In the 80’s I planted and cut beans with a 1947 Model G and a bean rake with a Model B. Those things were built to last. The planter was a 1947 Ventura. Farm equipment was being produced again after WW II. Europe and Russia were short on food production.

I worked for JD for 22 years and never seen one of those engines apart. Enjoyed the video. GW

You guys did a fine job on that old block better than new.

Brain: Man this is cool Also brain: 2:07 DOGGOS

It's a good channel and I say keep up the good work on your A/V production. Thanks for bringing it!

Looks factory new again. Cool job!!

Well done video with lots of good information. I've always wondered what those big two cylinder blocks looked like. Now I know.

Great video! Really enjoy all the content you post, including the shorts. You and your Dad have a nice business there. I hope you keep enjoying the work with him. I worked in my Dad’s small-engine shop for 5 years before I left for the Air Force. Was such a great learning experience. Keep the videos coming.

That was awesome!

Love the videos. I spent a lot of time at my grandparents place. My granddad had a B Model I think. It had the foot starter and what he called a suicide clutch. Didn't take me long to figure out why it was called that. Once it was engaged you had better give yourself room to break the clutch loose. This video brought back a lot of great memories. We put new rings and bearing in it when I was about 14. We got it back together and I can remember my dad's smile as he adjusted the carburetor down as low as it would go, it didn't have a tach so I can't be sure be it had to be something like 50 to maybe 100 RPM's I know it was a considerable amount of time between each cylender firing. Thanks for the videos and memories.

Awesome job!!!

Great job lads

Beautiful work! Well-filmed as well.

Loved it. Thanks

Certainly one of the more unusual engines you have shown

Great video. Lots of detail. Love it. Keep up the good work.

Great Job!!

This is something I have learned about taking broken bolts out !!!! If you bore them almost through!!! And put a welding in the hole and have someone turn the welder on and run the arc out and let it cool it srinks the bolt!!! Then weld to it to screw it out !!!

cool video... always fascinating to see machine work. Thanks

Great content. Great explanations. Great entertainment. Would like to see/hear about more obscure type engine building machine work like piston knurling and bearing shimming. I am sure y’all Probly never or rarely do such but it’s still pretty neat to see and hear about when parts are no longer available for old or rare motors.

Good job getting that broken stud out.

True artistry

Never had the opportunity to hang out in a machine shop. This was really fascinating.

Good work ethic and good people

Great work

I like your videos because there are about engines but also they are very educational

Awesome work!

Nice 👍 very big sleeve fitting and cylinder bore and hone👍

Great job

I I I don't know what to say? I'm at a loss for words. Perfect, comes to mind.

I hope that I can find a machine shop that is that meticulous and precise as you are. ❤❤❤❤❤

That was a lot of work 👍 great job !!!

Fun to watch👍👍👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻

You guys make a good team nice work boy’s

On the chamfer you did on the bottom of the sleeve/block intersection "blending" ... you did it right. Number one rule in machining is that there are NO "sharp edges" in metals ... causes crack propagation ... 40 years in Aerospace all over the World and my number 1 pet peeve ... LOL. Enjoyed watching you work on cast iron older than you and your Father's ages combined. GREAT JOB !!!

Great job, cool video!!

I feel sad that we only get to see the machining part... I'd love to see it put together and running again... These aren't a engine you see every day

Awesome video

It would be great to see the engine Running in tractor as followup Video plus the jag engine or anything vintage you rebuild thanks For sharing this video

Wow! I sure would love to work there and learn all that stuff! My respects!

Nice work bud!

Nice work

Great video...

Excellent work wish your in Michigan

I enjoyed your video.

Got to watch that heat! You could easily work harden the bore surface.

Nice. Keep up the awesome content.

Great job, new subscriber, thank u from nyc
