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.

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.

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.

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

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.

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

[@moderatefkr6666]

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.

A 70 year old guy showed me that back in 1970., you're the first one I've seen besides me use that method of crack repair since.

[@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

[@frankthespank]

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

[@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

Beveling won't work on cast iron you have to cut it out like a quarter inch wide or put another piece in while it's preheated very hot . Not worth the effort . Works great on the side of engine blocks between freze plugs or something with no stresses .

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.

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!

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

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.

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

[@MrBcummings8521]

What makes this better then grinding down the crack and welding it.

[@TatroMachine]

no need to redo all the babbitt bearings. tatro

[@danyonharvey7986]

I'm a casting's repairing weld credential and certified . It's easier to Cut down through the crack and to TIG weld it and to have using silicon bronze welding wire or 309 S/S welding wire and then everything can get on a milling machine and can be dressed back to the original size

[@TatroMachine]

i have tried alot of different welding rods and type of welding cast steel and cast iron over the years and most everything doesn't work for squat if at all. cracking is a bitch and the welding bead is so damm hard you can't do nothing with it. silicon bronze sucks if you have to machine it at all. i have not heard of the 309 s/s before. i have tried lots of high nickel welding rods before and they do not work very well at all. lots of cracking and very very hard to grind. machining is out with carbide tooling. tatro

[@safn1949]

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

[@irishguy200007]

How did it break off? Was this a special kind of shear bolt.

[@skooterbumm]

Ive used something like that except the taps and pins were tapered

[@TatroMachine]

i used both tappered and the shark tooth type screws in this repair. lock-n-stitch told me what and where to use both types. tatro

[@buteapot]

Nice job

[@cameronvandygriff7048]

Just curious if you’ve ever put the motor on a dyno and if so how much power did it make

[@lkkjhtemmexv1838]

[@richardfinney3179]

To peen them use an air chisel with a ball peen bit with a glove to hold the bit from bouncing all over yip it works great for the studs and some bronze welding rod on the deck nickel on the seat great job

[@osmargomes2068]

Excelente trabalho! Porém, ficaria bem melhor o acabamento utilizando a fresadora. É só uma opinião.

[@RareParts3769]

Sim. Parece que ele confiou na habilidade manual. E eu não encontrei a sequência deste vídeo.

[@suicidegrapes7302]

Got a question, now that the repair has been made, can a new casting be made from this original block?

[@TatroMachine]

you got a 100k to make the molds and have them casted. tatro

[@the_hate_inside1085]

Ask in Mandarin, the Chinese are good at that sort of thing.

[@rustyicepick8462]

Can a block repaired as in the video be boosted? How many pounds would be safe?

[@TatroMachine]

who knows, the stock blocks crack too. my race bike has these type repairs done to it and i have been running 60% nitro in it and tons nos for years now. tatro

[@miguelrivera2751]

Todo está bien eso que hiciste es un empernado o soldadura mecánica pero el acabado en el asiento es importante que hiciste insertaste asiento o nada más lo rectificaste un saludo de lztacalco cd de México

[@1967brokedude]

I would weld that ease with diffent metal and local heat treatment and then roll the dice ... because i have almost no patience. But i would PMI the block and cylider area first , then select the best filler metal and localized heat treatment .

[@TatroMachine]

sure sounds nice but that is not likely to work as you stated and it would have killed all the babbit bearings in the block. my way worked and did not hurt anything around it. tatro

[@jamesworsham125]

I used to use an air hammer and modified inserts for peening. Easy to hold the peening head and get it right where you want it. 😉

[@polishettybheeshma536]

perfect job

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

[@myrontaylor4250]

Very interesting. Never seen that done

[@zoesdada8923]

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
