@@JAMSIONLINE Ahh I see. Love that you’re working with your dad and that yall are keeping these older machines and techniques alive! Keep up the good work.
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 UA-cam channel.
I hear what you’re saying! I kinda like these old tractor engines but sometimes they are a LOT of work to do the right way. Tell your son I said thanks for showing you the videos as well! 😁
when you say "young one taking over the business" you should include that he'll either have his own son to continue the cycle or find someone (young) to be son like in continuing the journey. I once heard that a business' value inludes a book of LESSONS LEARNED -- i.e. 'don't do this' lessons.
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 had bought a Lincoln SA200 to rebuild. Ended up selling it to a pipeliner that would rebuild it. The thing was the Continental F-147 was meant to be rebuilt “in frame,” how ever the rebuild kit was 3X cost over a SBC.
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.
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 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..
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.
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
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.
@@regdor8187 I think that was meant to be a decompression valve, or a compression relief valve. (Yes, this is from someone finding the video a year later and you probably already knew what autocorrect mangled...)
"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.
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.
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!!
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!
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.
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 !!!
Also pro tip on "Bolt extraction" ... put a thin copper washer under the washer/nut and you won't weld to the steel/iron surface ... easier to turn the welded bolt ... won't bind up.
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 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 UA-cam- 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!
I’m an old mechanic and I remember when every CarQuest and NAPA had a top notch machine shop in them. That was back when they catered to professional mechanics. Now they’re no different than AutoZone peddling Chinese garbage parts.
I’m sure that was a really hard market with all the recyclers down there and wholesalers ever one now days just wants to swap out for new or reman , I’m outside of Yakima and my father in law was an old school mechanic / machinists after he passed no one wanted any of his valve and head machines , I didn’t know how to use them , I did find someone that would take them and a lot of tooling … I think the tooling is what they really wanted . Hopefully they got some use out of them . I watch eBay for a while just to see if they went straight up for auction ?
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.
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.
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".
Very nice job. Literally better than new! Just an idea, make a threaded bushing or use the steel part of an old spark plug as a guide to drill your new holes, it'll center the bit.
ya i will second that . as it just to ez to slip with that drill and get into the org. threads doing it free hand . a drill bushing that is tap drill size for the spark plug thread on the o.d. but if you could set it up in you seat and guide machine then you could just float it in but at that angle it would be a beach . but hey it look like you have done this a time or two so do what works for you
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.
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.
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
Good job on them spark plug hole when I was in highschool and college I work in a machine shop, I would have been stressed out drilling them hole how you did it without messing up them thread's, I thought for sure it was going to be threaded insert time btw I recently started following y'all I love the channel 👍👍👍
One request. Can you please show us what it looks like when its not setup in the correct position? Like when you first check the centering of the bore and then what you got it to final setting! Thanks for the Content.
Nice work! One question; why do you center up multiple times? Couldn't you use your DRO to save all the cylinder locations in x and y? I own the same Mitutoyo DRO and you can store at least 9 positions. Find tour center, Hit the datum key on the DRO and select a number from 1 to 9. The small display at the top right will show this number. Then hit the x and y key's next to their display and they will go to zero. When you want to return to the center of, say, cylinder two hit the datum key and punch in the number 2 (confirm with the "load" key). Now move your x and y stages until both axis show zero again. Maybe I'm missing something here. If so please let me know. Best, Job
Totally understand where your coming from when talking about Cast Iron ?? I HATE machining it ???? 30 minutes of machining time, 1 hour to clean the machine afterwards. Especially when turning it on a Lathe. I hate bloody stuff, LOL. I was surprised to see a Cold fitment of the sleeve ? I have only worked on Motorcycle cylinders so might be a different procedure to fit sleeves ? Sunnen are Definitely one of the Best Honing Machines available, a bit of a pain of a job having to Hone the cylinders the way you did. But at the end of the day the job was done well. Big Thumbs Up. Thanks for bring us along for another day in the shop. All the best. Peter.
Out of curiosity, are they going to be running those pistons without a bottom (or rear) oil ring. I'm not sure on the late model A like that one, but I know some of the 2 cylinders run the bottom oil ring all the way to the edge of the cylinder, and with that last 1/4 inch of the cylinder being .045" larger, that can cause the ring to snag. That it one of the difficulties you can run into with sleeving the old 2 cylinders. I've heard of some running the pistons without that rear oil ring without any ill effects in order to make it easier to sleeve the block. The other option is counter-boring the top of the block so you can run a full length sleeve.
Well! I guess this will either be a learning experience, or it will be fine! If it’s a learning experience, I’ll make a follow up video for how we fix it lol. Thank you guys for pointing this out because this is a critical oversight on my part, so I will be checking w/ my customer to make sure we are okay here!
Very nice job. My best friend restores old JDs. 2 As, 1G, a 730, several others. Most expensive thing on whole project per results is authentic John Deere paint from dealer. Crazy expensive
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.
We had a 1938 A Model JD back on the farm in Tx. Started on gas and transferred to kerosene, was cheaper fuel. It was not electric start, release compression and spin the flywheel. Your magneton had to be good and timing right.
little tip, when welding the little hack for taking out the broken bolt, try to use a washer that's the same size dia. of the bolt you're taking out (looks like you did), but instead of trying to get a good weld inside the nut, use a size smaller nut and weld it around the outside instead, or better yet, a couple sizes larger bolt, as short as you can find, and weld threaded end to the washer/broken bolt part. It seems to transfer heat better into the hole part of the casting, doesn't super heat the nut, and gives you a better weldment.
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 !!!
I didn’t realize they have a decompression valve on each piston like that that’s cool my dad has an old John Deere chainsaw that has a decompression valve on it to
@@scottborst5430 with the decompression valves not open on my john deere A I cannot get it to turn over at all, I wish it had electric start but it's too old for that.
@@jacobdevereux207 Yeah that sounds about right unless you could find a way to put a fly gear and a starter motor on the driveshaft but it just look ridiculous And how would you find the starter motor it’s not gonna be too powerful to mess things up
Why didn't you heat the block up to expand it before installing the sleeves (AFTER you finished machining the bore I mean)? Wouldn't it make it a ton easier to install the sleeves and give less chance for damage to the sleeves? Thanks.
What are the symbols and letters popping up throughout the video?
They were supposed to be captions, but I botched it! I am going to try and fix it later but no promises lol

So when it comes to balancing the crank, do you still use grams for piston weight or is it easier to use short tons for those monsters?
Great video. Lots of detail. Love it. Keep up the good work.
Great video! Thanks for sharing!! Why do you wait to remove broken fasteners until after you've invested a lot of work in the piece? Thanks again!!
Thats a very fair question.
Because they are machinist and they know it coming out one way or the other.it don't have a choice in the matter.
I have.
To say those cylinders look pretty good When you were done before you Added the sleeves
I’ve have a jd A hopefully nothing happens to the cylinder because that was a lot of quality work to bring it back to stock
I I I don't know what to say? I'm at a loss for words. Perfect, comes to mind.
Great segment
Never had the opportunity to hang out in a machine shop. This was really fascinating.
I love watching videos like this. This would be my dream job
Amazing how much pulling power guys get out of those big ole 2 cylinder engines.
Totally understand where your coming from when talking about Cast Iron ??
I HATE machining it ????
30 minutes of machining time, 1 hour to clean the machine afterwards.
Especially when turning it on a Lathe.

Excellent feel for machinery. And a great video. Hope they made enough money on that job.
Thank you! Seems like we never do. Lol
Out of curiosity, are they going to be running those pistons without a bottom (or rear) oil ring. I'm not sure on the late model A like that one, but I know some of the 2 cylinders run the bottom oil ring all the way to the edge of the cylinder, and with that last 1/4 inch of the cylinder being .045" larger, that can cause the ring to snag. That it one of the difficulties you can run into with sleeving the old 2 cylinders. I've heard of some running the pistons without that rear oil ring without any ill effects in order to make it easier to sleeve the block. The other option is counter-boring the top of the block so you can run a full length sleeve.
That's my concern also. The oil ring runs all the way to the very back of the cylinder on a late styled A.
Well! I guess this will either be a learning experience, or it will be fine!
If it’s a learning experience, I’ll make a follow up video for how we fix it lol.
Thank you guys for pointing this out because this is a critical oversight on my part, so I will be checking w/ my customer to make sure we are okay here!
I hope everything works out well! You guys appear to be doing beautiful work and I'm really enjoying your videos.
@@JAMSIONLINE It's too bad that no one makes a stepped sleeve for that application. That would seem to be the best solution, in a perfect world.
Love watching these video's. You and your Dad do great work.
Very nice job. My best friend restores old JDs. 2 As, 1G, a 730, several others. Most expensive thing on whole project per results is authentic John Deere paint from dealer. Crazy expensive
You dads a cool guy gather his knowledge while you can, love your content
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.
We had a 1938 A Model JD
back on the farm in Tx. Started on gas and transferred to kerosene, was cheaper fuel. It was not electric start, release compression and spin the flywheel. Your magneton had to be good and timing right.
You guys make a good team nice work boy’s
Beautiful work! Well-filmed as well.
Looks factory new again. Cool job!!
Excellent work wish your in Michigan
That was a lot of work 👍 great job !!!
little tip, when welding the little hack for taking out the broken bolt, try to use a washer that's the same size dia. of the bolt you're taking out (looks like you did), but instead of trying to get a good weld inside the nut, use a size smaller nut and weld it around the outside instead, or better yet, a couple sizes larger bolt, as short as you can find, and weld threaded end to the washer/broken bolt part. It seems to transfer heat better into the hole part of the casting, doesn't super heat the nut, and gives you a better weldment.
I like your videos because there are about engines but also they are very educational
Well done video with lots of good information. I've always wondered what those big two cylinder blocks looked like. Now I know.
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 !!!
Good work ethic and good people
It's a good channel and I say keep up the good work on your A/V production. Thanks for bringing it!
Wow! Incredible machines! Very exacting work. Nice job!👍
Fine job... Not many folks do those anymore.
Better than new perfection that’s what makes repeat customers
I didn’t realize they have a decompression valve on each piston like that that’s cool my dad has an old John Deere chainsaw that has a decompression valve on it to
trust me those decompression valves are very well needed when you have to start it by hand.
@@jacobdevereux207 Oh yes I could not even get one rotation with the decompression valve shut on that chainsaw
@@scottborst5430 with the decompression valves not open on my john deere A I cannot get it to turn over at all, I wish it had electric start but it's too old for that.
@@jacobdevereux207 Yeah that sounds about right unless you could find a way to put a fly gear and a starter motor on the driveshaft but it just look ridiculous And how would you find the starter motor it’s not gonna be too powerful to mess things up
@@scottborst5430 Electric start from an early styled tractor bolts right on the older tractors.
Wow! I sure would love to work there and learn all that stuff! My respects!
Lookin' GOOD!!!!
I enjoy the videos; Question , are there arbors available to grip end mills, .5 dia.
You have done an incredible job with that block. Wish I knew where you were located so you could do mine!
Why didn't you heat the block up to expand it before installing the sleeves (AFTER you finished machining the bore I mean)? Wouldn't it make it a ton easier to install the sleeves and give less chance for damage to the sleeves? Thanks.
