[@dirtyroofer3678]

Love them old cars , thanks for helping to get the Franklin up and running.

[@kooldoozer]

Old cars are rolling history. Hope you enjoy my channel.

Jonathan W. sent me. I just like watching you guys do your stuff. The workmanship is amazing! 👍

[@kooldoozer]

Nurses are always welcome in my shop. Thanks for the appreciation. Hope you keep enjoying my videos.

[@darrenfarr4890]

Impressive talent from regular guys. Always entertaining and informative, revisiting defunct and forgotten American road iron reflecting on what might have been and might be again thanks to JW and posse! Noah is one fortunate dude learning from these fellas.

[@kooldoozer]

I am very happy to be helping Jonathan with this project. I have a strong respect for the engineers of the past. I would really like to teach a college course about the history of engineering. Most people hear Tesla and they think of the car. I think he is the man behind the reason that the lights in my house are on. I love when Jonathan told the story about Charlie Taylor. Maybe he and I should teach a course together. Noah is great. I think he is learning so much. I try to teach the engineering interns from college where I work. They are the next generation of thinkers. Gotta share with the next generation, get them off their phones and into making things. Enjoy. -Doozer

[@darrenfarr4890]

You are a valuable asset to society above and beyond these projects, sir, and hats off to you and all your endeavors. Noah and all your students have first rate instructors.

Jonathan is lucky to have you as a friend. I never would have thought of repairing a piston with major damage. I am humbled by your skill and ingenuity. Thank you and keep teaching. I will subscribe and learn. Have a Merry Christmas!

[@kooldoozer]

Thanks for your kind words John. I have practiced a lot with the aluminum welding and it took me a long time to get good. I am at the point where my welds are generally good, with proper penetration and no porosity. But I will never be as steady as someone who is a career weldor. But I keep practicing. Fixing old cars preserves the legacy of history and technology. People think they are hot stuff with their computerized this and that. These old machines paved the way to make their modern effortless life possible, and they all forget that. A modern car is impressive, it is all built on the shoulders of the inventors and innovators that built the old cars. The old Franklin is more impressive to me than a new Cadillac. Merry Christmas.

[@grantw.whitwam9948]

Is that we used to call a turret lath, we had one of those when I had Machine Shop in High School 1972. Brilliant way to hold the piston securely.

[@kooldoozer]

Yes, it is a turret lathe. Enjoy my channel. Thanks.

[@TidyThreads]

Mind your hoodie strings in that lathe

Subscribed ! What on earth is that machine for ? Carding cotton is my guess. Very cool. Hope you enjoy my channel.

[@TidyThreads]

@@kooldoozer Welcome to my channel. That machine is the top half of a machine, The bottom half has been in a open barn in the hills of Wales for 30 years. The top machine is 1060s i think and the bottom machine could be anywhere from 1930s-1960s. I'm going to refurbish them both over the next year.

[@scania357]

Nice to meet you, Jonathan recommended you. Maybe you could do a shop tour👍👍

[@kooldoozer]

Thanks Steve, Nice of JW to send you. A shop tour is a great idea. Maybe soon. Would be a 2 hour video, as I like to tell some history of each machine. Maybe lots of short videos, one of each machine.

[@retireddec04]

I like that workholding set up.

Ok I do like that idea with the draw bar on soft stuff thanks !!!!

[@kooldoozer]

The machinist trade is always learning. That is why it is so much fun.

[@xozindustries7451]

Very cool. Are you going to weld it on a rotating jig?

[@kooldoozer]

I tried to spin the chuck as I welded. I even fixtured the torch head in position. Not good for this job. I really need a motor to run it and a variable speed foot pedal. Just to cumbersome trying to hand spin it. The torch really needed to be held in my hand to get the puddle in the perfect place, so that is what I ended up doing. Too awkward to film, sorry. But I learned a lot. Better next time is the name of the game. Thanks.

[@nickjervis8123]

Hi I do a fair bit of model engineering using a pre war Myford lathe. Also do hobbing with a hobbing machine. Make live steam locomotives Also following JW as I own and run a 1940 Buick Super 8 and a 1952 Buick Roadmaster and a 1954 Packard Patrician straight eight as well as a 1948 Ford F5 here in the UK 🇬🇧 Ask the man who owns one

[@nap8187]

Good collection there Sir!

[@kooldoozer]

I always thought the Packard Patrician was a good looking car. Anything with a straight 8 is mega cool. Thanks for stopping by. Cheers.

[@richvandervoort2950]

How hard will the welded area be in relation to the existing piston hardness? Do you have any information on the properties of the aluminium from which the piston is made?

[@kooldoozer]

Not sure what Levett used. They called their aluminum MAGALOY which might suggest some magnesium in the melt. I used 5356 filler metal for the weld. It turned like 7075 aluminum on the lathe. Might be higher silicon alloy. Not totally sure. Sorry I don't have a better answer. Hope you enjoy my channel.

[@manic_tinkerer]

I opened this vid with one eye closed after seeing other "machining a piston" videos with pistons being ruined in wobbly setups in mini lathes and some bubba declaring it was good enough, but then I was surprised. I really like the method to hold the piston by its pin so the forces are in the boss, and will probably adapt the idea and make a large rod eye drawbar setup that use the 4 jaw to centre the pull rod so it runs true in a similar manner rather than internally clamping the skirt. Also you indicated on the crown rather than on the skirt. On more modern stuff the piston will be oval across with the narrowest section inline with the pin bosses and barrel shaped in vertical profile but on this vintage its probably just a straight round casting machined. Decent bit of home shop craft there and no stupid fake drama tv host style.

[@kooldoozer]

Thank you Jmp, I appreciate your views. Good to know someone else out there has a concept of how to fixture and how to indicate things. I was trying to teach just a little bit in these piston videos on some lathe techniques. I agree, lots of guys out there just slap work in a 3 jaw, and assume it is all good. Blows my mind. Well, if ya don't know, you wonder why things turn out so poorly. And nobody blames themselves. That's not the world we live in today. The fix it yourself concept is great, but nobody has any skills or common sense. I am just a mechanical engineer, but I have had a lathe since I was 15 years old. I bought my first dial indicator and calipers at a flea market, just to be able to measure what I was making in my lathe. Machine work is geometry. Plain and simple. Workholding is just a geometric problem to solve. Just like modeling something in CAD. Align the axis of rotation or plane of flatness, whatever. I see many people do not begin their thought process for solving problems at the beginning. They just make assumptions that things are straight and flat or whatever. You can if you know your machine and know your tooling. But otherwise, you have to indicate and measure everything. I hope you enjoy my videos. --Doozer

Nice job, new sub. What model is that tsugami lathe?

[@kooldoozer]

Tsugami T-SPL-1 lathe. It is a copy of the Hardinge HC lathe. Every bit as nice as Hardinge, dare I say even better. Thanks for the sub.

[@donnlowe9129]

Clean the aluminum with Acetone?

[@kooldoozer]

I just turned the surface on the lathe. Cleaning with acetone is usually superfluous. I keep seeing it getting recommended, but I don't think the people recommending that practice really know if it is doing any good or not. I mean, it's like thousands of degrees here ! A spec of this or that is going to either turn to carbon or vaporize to oblivion ! This piston welded like butter. Whatever alloy they used in 1927 was excellent.

[@bengkelku]

Good...

[@kooldoozer]

Thanks !

[@TierodMcslush]

What kinda lathe was that again? 🤣

[@kooldoozer]

Tsugami T-SPL-1 lathe. It is a copy of a Hardinge HC lathe, very precision lathe. I really love it in spite of having a Hardinge HLV-H. It is just so handy, I could never sell it. There are a few on ebay. They mostly are found on the west coast, which is where mine came from.

So why are you cutting the piston

[@repairrestoreresell2026]

I liked that workholding idea. Did you swipe it from the U.S. Marine Corps? "Adapt, Overcome & Improvise" I'll remember it and maybe one day I'll have an opportunity to put into practice. Just subscribed and looking forward to your future video's. Best of luck.............................

[@kooldoozer]

Thanks for the positive comment. The drawbar in the piston pin idea just seemed natural to me. I work a lot of fixturing stuff. I guess I have a knack for seeing things. Thanks for watching and enjoy the content.

[@patmclean1951]

You’re presentation got better the longer you were speaking. The hoodie strings are definitely a concern. You seem to know your stuff!

[@kooldoozer]

Next week we inflate tires with either at Doozer's shop. Watch this space. Thanks for the views.

[@davidakin1481]

O ok going to weld it think you would get new one's

[@kooldoozer]

As Jonathan said in his video, new ones that might match up could be found for an Allis Chalmers tractor or a Continental engine. But it is my belief and Jonathan's belief that if something can be repaired in a reasonable way, it is an effort to allow the object to continue to live on and it adds to the provenance and history of the object. No now a piston made in 1927 continues to perform it's task for the owner. I am fighting hard NOT to be a member of our throw-away society. Yes, it is that important to me. Hope you enjoy my channel.

[@davidakin1481]

[@hydroy1]

The Franklin is Johnathan's most interesting project. ( in my opinion ) A Aluminum body with a WOOD frame and a air cooled motor. If your really going to get this right, use a really good bore gauge ( not all bore gauges are the same in quality ) and check each bore everywhere for straightness, ware & tapper. Then Mic the piston skirt's very closely all around each piston and find out the skirt clearance to bore size . That is the most important size.

[@kooldoozer]

It made it easy for me to size the ring lands, because they are always undersized from the skirt, and I had the original diameter to measure. I would gladly lend Jonathan my dial bore gauge, but he is just going to re-ring it, and use the original pistons. Hence the work on this piston that I did for him.

[@hydroy1]

@@kooldoozer Be worried about heat distortion from tig welding on old cast alum pistons as they tend to move like crazy from welding !!!!

[@kooldoozer]

@@hydroy1 Well, Mike, I hear ya. But Honestly I was not worried about distortion. These are slit pistons. They are not cam-ground pistons. Also the Franlkin is an air cooled engine, essentially an airplane engine. Piston to bore clearances are large, to deal with a lot of expansion. With the ring lands being blown out, and if I did not weld it, the piston was going to be junk. Many reasons not to be concerned about distortion and also many reasons to just weld it. I had nothing to loose and everything to gain. Worrying about things is only when I have no information to make an informed plan of action. I had considered many data points before I accepted this job from Jonathan. If things went to heII, I could always make a new piston. I tend not to worry about mechanical things. --Doozer

[@hydroy1]

@@kooldoozer I though he found a current production piston & rings that would work for the air cooled Franklin ????

[@kooldoozer]

@@hydroy1 Not since we last talked. Jonathan found some Continental piston rings, the right bore size, but they were too narrow or something. But I would not have welded up his original piston if new ones were available. But I will ask next time we speak.
