1932 ford

1932 ford #104 model A or B flathead race block crack repair by tatro machine
I used lock-n-stich crack repair pins.
I used both castmaster and tapered pins to fix the cracks
this model A block was run in a lakester at Bonneville without water. when that happened it over heated the block and cracked the one cylinder and intake port.
all these ford flathead 4 cylinder blocks from 1928-34 are about the same so this repair should work for them too.

[@andrewwilson8317]

Cold stitching a perfectly valid way t effect a repair. The screws I have are slightly tapered and shear off at the right torque. The overlap ensures they can't unscrew. I put a slight countersink on the job to give me somewhere to plannish the screw into after it has sheared off. The engines I have done have passed pressure testing and are proving to be reliable in service. The oldest repair is now over thirty years old and still going strong! Keep up the great work, it's the end product that counts above anything else!

Need to spend time in a junk yard with only basic hand tools and go create something good. Want to see if can still do it. Want to do a roof chop with only hack saw,files and hammers and lead load with recycled scrap lead. Ultimate test of a rodder?

I'm 25 and I love going to the junkyard and walking around seeing what's hiding in vehicles. It's amazing what you find I've got good parts from there. Use nothing but hand tools and a mismatch tool box of sockets and bits I got on hand. I keep losing shit lol! Gotta stop at harbor freight and get some half decent replacements. Yanked a set of heads off a old vortec 350 some weeke ago. It was a pain but worth it.

The kit is from Lock N Stitch in Turlock Ca. I lived there for many years and that place is busy all the time. This type of repair has been around for many decades and works very well as this guy is showing the right way to do it. You drill into each screw so they are locked in place. They will never move!

I have to say I have never seen or heard of this type of repair. I am amazed and impressed and added another tool to my arsenal. It's great to see how it was done back in the day. I have done alot of repairs people said couldn't be done only because it's all I could afford to do. People said you can't do that. I'd say watch me. I remember being about 8 years old and lost the spring clip that holds the master link on a bike chain. We got pop bottle caps and a chisel. Cut the caps into small squares and punched a hole in the center of them with a nail. Took a pair of players and snapped the pieces over the links and rode the rest of the summer without a problem. As for all the dumbasses saying the block is junk get a new one, weld it, ect... I'm sure they don't know which end of a screwdriver to use.

[@tomhutchins1046]

You use special tapered pins and a special tapered reamer and tap. If done right it is very durable. The pins are cast iron so it should be a similar expansion. This is an old method that is used on more than automotive applications. I used to dip the pins in K+D block seal before installing them. A friend bought a mid 70's camaro with a 6 cylinder the one with the cast in head intake. There all cracked you cant find a good one . I put 56 pins in it really! He used it as a bart car to leave in the city were he worked and get around when he rode the train to work. Lasted at least 15 years till he retired then he sold the car last I heard it still runs. I would not do it to a normal customer to much risk but he was a friend and it was disclaimed clearly. Did a Hudson hornet block once also and other's no failures but you need to know the tricks. Im semi retired now dont miss pinning cracks ! Sorry for the long comment on your channel Tatro

Grind the crack into a U shaped valley then heat the block with a Victor rose bud in the area to be welded until it is over 500 degrees and use Graphite Cast Iron Welding Rods. Watched my dad and grandfather both do stitching as this. But that is not the preferred method today. I've restored several old tractors, and a few boats for friends over the years with cracked blocks and if you have a deep BBQ Pit you can heat the block in it also.

I guess it's 7 years too late to ask why you didn't use a starter tap. But if the idea is to lock the thread in the hole, then maybe it's not desirable to have even a started thread down there. Thank you for sharing this interesting process.

[@TatroMachine]

what is a starter tap. all taps have starting threads on them, even the ones i used. tatro

[@G58]

Tatro Machine you asked: “what is a starter tap. all taps have starting threads on them, even the ones i used.” I trust you’re joking. A set of taps contains three taps known as: Starting, Intermediate and Finishing or Plug. They’ve been around for over 100 years. I used them when I started my aero engineering apprenticeship in 1974, but I first used them in school metalwork class. You apparently used a Plug, which is difficult to get started. The first Starter tap is most tapered with virtually no thread on the fist part, which is inserted into the hole. This helps to align the tap correctly and prevent a mashed start and crooked thread. This is less useful when tapping short blind holes, but fine for through holes. I hope this helps.

[@grantreid8583]

We use a similar method in Australia but our tap is tapered and so are the plugs. A plugs we called them and there was a bigger B plug rarely used from memory they were made by W&B. The plugs were made from cast iron the ones in this video look like steel ones i believe the cast ones would be better in a cast block. First started using them 45 years ago as an apprentice. When i was working in Papua New Guinea we used the same tapered system and the locals there were extremely hard on their diesel vehicles mainly toyotas and it was not uncommon to fit over 60 plugs to a cracked 6cyl diesel head on an almost daily basis. We even repaired caterpillar heads gm diesels whatever could be cooked we repaired it using the A plug system sfterwards we usually pressure tested them and it was rare to ever find a leak. Ps i won't say what the locals could do to a crankshaft in a diesel vehicle that has never had an oil change!

[@TatroMachine]

i used a mix of tappered plugs and the straight ones. the straight ones pull the two sides together and the tappered ones push them apart. you can pick and choose which type you wanted to use. the cast ones would have been better in the cylinder bore. either way, the old ways still work just fine. tatro

Everyone: “Drilling hole” Machinists: “Cutting” 😝

[@Oldbmwr100rs]

Learned about this in auto school back in the 80's, but never watched anyone do it. I'm glad they taught it though because it came in very handy years later when I was at a shop and a Merc Comet came in with a couple broken bolts in the water pump. In drilling one out, I found it was originally too long and was bottomed against the cylinder, and I drilled through it extracting the broken bolt! Luckily it was only a 3/32 hole, and remembering this I partially tapped the cylinder and made a soft steel plug from a screw and carefully ran it into the cylinder, then peened it over, I used my borescope to make sure it wasn't going through into the path of the piston. It worked perfectly! As it was at the time the customer was planning on putting a V8 into the car anyway, so the fix wasn't going to lead to a long term problem as that engine was coming out in a few months.

[@rogerrabbit8297]

[@buteapot]

Nice job

[@BrokenLifeCycle]

I think I figured out how it is holding the crack together without splitting it like wooden end grains. The screws aren't drilled straight down into the crack but at an angle away from the crack channel, thus the threads help provide some lateral force to support the crack just like Metalock keys. I don't think it's as strong as following the correct procedure, but if it's enough, it's enough.

[@TatroMachine]

this is a correct procedure. that is why this stuff works. if you look at the two types of screws i used you can see how and what they do. this was done by the manufactures recommendations. one type spreads and one type pulls in. i angled drilled so that i would not drill out the other screws that i just got done installing. all of this was stated in the videos. tatro

[@autophyte]

Doubters, Google "Lock'n'Stitch". You'll see that it is a valid and proven method of repairing cracks in cast iron. Welding doesn't work because of contraction of the metal on cooling, which, in cast iron, with very little elasticity, only cracks worse. Preheating the whole block in an oven MAY ensure no cracking on cooling but would require re-grinding of all surfaces to restore 'true', line boring of the main bearings, cam bore, etc. Not worth it. As for the valve seat, the old one can be cut out and replaced with a new one.

[@TatroMachine]

all true except for the valve seat part. there is no valve seat, that is the block. if you watched me drilling the holes in the valve seat are you would see that with all the porting the block is very thin in this area. parts of this is less than .050 and most is under .100 thick. these leaves no room for a valve seat insert. the only option was to do what i did and use the pins as the valve seat. tatro

[@geodes6722]

Excellent video. I am repairing two vortec heads using this same technique. Time consuming but not really difficult. I have a question and perhaps it is covered somewhere in your videos and I may have just missed it. When you completed the stitching on the cylinder did you simply rebore the cylinder or did you sleeve it? Was curious as to how the cutters on the cylinder bore reacted with the pins. Seems to me it would have made sense to sleeve that cylinder. Either way understand it had to be pinned regardless to keep that crack from spreading further. Great video!

[@TatroMachine]

that was all covered in the later videos. sleeving is best but that was not an option on this one. tatro

Serious question. Why would you do this instead of drilling the ends of the crack and welding it shut? Not trying to be a smartass, I'm really just curious. I've never had the misfortune of having to repair a block before.

[@TatroMachine]

cast-iron is extremely hard to weld. it get very hard when you weld it. that is it gets so hard a grinder does not what to cut it. next is that is is so hard it cracks very badly because it does not flex at all. it only takes a drop in temp of a few hundred degrees and it recracks. drilling holes does nothing to stop cracks. stopping the stress does. tatro

[@TatroMachine]

no, the screws are the same material so they would do the same thing when hot or cold. tatro

[@Fuddleton]

The correct repair is welding over the crack and remachining. Peening does not join material even if it looks like it's joined, but if it works, I'll still applaud you I guess.

[@accretiacat]

Actually, this method is better. Drilling, tapping, lacing in the repair bolts with ceramic locker and then peening is stronger than welding it. It does less damage to the surrounding metal in terms of changing the metal properties. Not saying proper welding technique won't work. Just saying this process is better.

Yikes...I have done the top crack repair many years ago in a couple of flathead jeep motors, but I have never seen this done in the valve seat area. Interesting.

[@TatroMachine]

if its broke, i fix it. too nice of a motor to toss it for just for a little crack. tatro

[@cameronvandygriff7048]

So glad I’m not the only one who noticed this is the valve port I see all these people talking about how the piston is gonna hit those pins when that’s not even a cylinder which is obvious if they’d just look at his tools or the bolt hole or his fingers relative to the size

[@Neildo430ci]

@@cameronvandygriff7048 it does go into the cylinder, but can't he just resleeve it

[@cameronvandygriff7048]

@@Neildo430ci theres still the issue of the crack it has to be repaired regardless if you can fix everything with one process why do two or three

[@79huddy]

I used a seat cutter and machined a port oversize and made my own sleeve out of aluminum bar stock then machined for a new hardened seat and peened the new seat in to hold it all in there that old hercules six is still running in an old tug boat

Why not weld it and then smooth it back out? How do these bolts help? Ive seen this process before but I never asked why it's done.

[@TatroMachine]

the screws do less damage than welding does to the block and still get the job done. tatro

[@myrontaylor4250]

Very interesting. Never seen that done

[@williamfunes2740]

Very nice. If it works it works!

[@joedell71]

Hi Tatro. Great video. Very creative thinking to get fire back in that motor. Quick question. Why didn’t you grind out the crack and weld it up instead of using the plug??

[@TatroMachine]

have you ever tried welding cast iron? its a crap shoot at best. tatro

[@joedell71]

Tatro Machine Yeah that’s what I figured. Just didn’t know if there was another reason to use these inserts.

[@colbysmith1398]

Nice video. Question, why couldn't you just drill the end of the crack, trench the crack then weld it up? Heat issues?

[@TatroMachine]

read the my other comments. too tied to say it for the tenth plus time. tatro

[@magdalenaadamczyk9201]

Can someone tell what kind of screw are using there? What materiał they are made of?

@@bmb990 Да херня, что там пара другая лимонов, Вы хоть знаете сколько стоит чугунный блок для судового дизеля.

[@user-xq3ex3ji3o]

@Петров Дмитрий Алексеевич Это для видео было сделано, на моей практике так восстановили не один восьмицилиндровый дизель с наддувом судовой. Спецы были из Питера. Цен не помню но блок стоил приблизительно как 3х комнатная квартира в центре с ремонтом и мебелью.

[@user-xq3ex3ji3o]

@Петров Дмитрий Алексеевич Причём здесь бракоделы, дизель разбирается и все детали моются, потом проходят дефектовку, делает её инженер обученный, и если на блоке находит трещины то он идёт на переплавку. Данная технология позволяет эксплуатировать чугунные блоки с трещинами но не все.

@Петров Дмитрий Алексеевич Пять лет работал механиком цеха по капитальному ремонту судовых дизелей, занимался обкаткой их после капитального ремонта.

Why just not heat up the head and weld it with an high Ni electrod, is this better than welding it?

[@keithlucas6260]

It's called "cold process." Using a tig and cutting everything would be the alternative. once this heats up bad things happen.

[@vitor900000]

True. This kind of repair more indicated for structural pieces. If there is heat and friction the difference in hardness and thermal expansion will cause a lot of trouble. If you do that to a cracked engine cylinder, pistons rings will explode in no time... At best you will get a lot of blowby.

[@soufyanedz9688]

Can make holes and braze it or weld it with tig or arc and remove the exceed with lathe

[@TatroMachine]

you are dreaming and have never worked with cast iron. google how to weld cast iron some time. tatro

[@soufyanedz9688]

Cast iron can be brazed and you can weld it after heating where is problem

Cara, isso não vai funcionar, os metais tem propriedades diferentes, não? Quando esquentar, um vai dilatar mais que o outro... Era melhor arrumar outro bloco.

Never seen this before. I could of welded this but it would take a lot more prepwork and more expensive. And need machined after .

Is that a dremel tool for grinding.
