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 KZbin channel.

[@JAMSIONLINE]

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! 😁

[@tomtke7351]

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.

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.......

[@duanepierson4375]

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.

[@mr19471985]

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

[@timwhite880]

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..

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.

[@jon2140]

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]

Well, with a thorough "decomposition", what is left to run? ;^)

[@moorepower7]

9" bore G???? Not buying it. I've been involved with several 8" Gs and know what it takes to make that happen, there isn't another inch on each side.

[@heyallenify]

​@@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...)

[@puzzled4163]

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.

[@JohnH20111]

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 KZbin- 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.

[@allensandven0]

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 ?

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!!

[@gaetanbolduc8417]

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!

[@craigsowers8456]

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 !!!

[@craigsowers8456]

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.

[@douglaswalker8563]

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".

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.

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.

[@chrisjarvis4449]

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

[@mdouglaswray]

Beautiful work! Well-filmed as well.

[@jobkneppers]

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

[@kevinjohnson7693]

True artistry

[@gboots9009]

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.

[@andyaho9729]

That's my concern also. The oil ring runs all the way to the very back of the cylinder on a late styled A.
