Magna cum mustie

[@jackmanatee3162]

Mustie, you've taught me EVERYTHING I know about working with small engines. So much so that I've made it my mini retirement business. But what you were doing with the lathe had me squirming in my chair. Like listening to a dental drill in the waiting room. 😮

[@Digital-Dan]

A 1950's era dental drill, belt driven, without Novocain. I still remember. . .

[@Scodiddly]

Steve Martin as the sadistic dentist in Little Shop of Horrors. "It's an antique! Sturdy... slow... dull."

[@DDLovett]

I keep seeing glimpses of that gorgeous pickup truck and wonder when Mustie will finish it.

[@tempusveritas8901]

Agree I didn't think he was that far off from finishing. Throw him an offer.

[@guyina4x499]

​@tempusveritas8901 he mentioned in a video that he wasn't happy with how something was going on the truck. So he was taking a break from it. Been a pretty long break now.

[@markbrown6236]

I'm waiting for it's return to Musti's attention.

[@robertschmidt6383]

I mean no disrespect cuz your a hell of a mechanic. I had to chuckle when you were trying to center that drill rod on the motor shaft. I telling myself he should cut the rod to match the center hole on the shaft. It would center itself then .Also use a flat push block on the live end instead of a drill chuck. Those drill clamping shafts can bend and be out of round. Just some thoughts. Also use a calipers to measure on a lathe. Makes life so much easier.

[@stevenmessinger8067]

Darren's so multi talented: fixing,filming,narrorating,lighting,editing and so much more

[@2barrell]

Darren, if you dont watch Cutting Edge Engineering you should. Kurt is a very knowledgeable machinist and welder. You could take some of his experience and add it to your tool box. Your ingenuity with solving problems is remarkable. Thanks for your videos i look forward to them.

[@Digital-Dan]

Or at the other end of the size spectrum, Joe Pi. Incredible machinist.

[@jamesw9930]

Yeah, Kurt is probably the best machinist / equipment mechanic on YT.

[@TheHortond]

I enjoy watching these rebuilds or tear-downs of Kohler engines. I have a horizontal shaft Kohler engine that I wanted to put into a Yamaha golf cart that has been sitting since the plandemic. Just waiting for me to start on it. The videos here help me, because its all a mystery on what goes on in there. I think now that I'm seen a few I know that they gas should stay hooked to the governor so it doesn't blow when someone else drives it. The clutch is all that is needed to fit on crank shaft. A belt goes from there to the transmission on the back wheels. I think I would be in business. If I made videos about some of the stuff I do I think it would be entertaining. A lot of trouble shooting with very little MacGyvering. Sometimes. Anyhow, I think I might get that running before the end of summer now. Wish me luck. And thanks for your help and inspiration.

[@timareno9017]

Awesome video. Love the ingenuity with coming up with solutions. After welding the shaft you could always turn it down to remove run-out. Looks like a powerful design. Anxious to see how it works out. Thanks

[@daleburrell6273]

...it's better to use a coupling-(!)

[@gispel7058]

3 jaw chucks often have less accuracy than a collet . I will reposition the piece in the three jaw ...until the optimum true position is found.

[@andrewwakefield4519]

As someone who is a machinist, albeit of the experienced hobbyist variety … this was painful to watch. 6 thou of runout on a crankshaft? Chipped brazed carbide cutting tool?? Chatter from an unsupported shaft a mile out of the chuck??? Welding a high carbon steel with no preheat???? Grinding and sanding grit all over the lathe ways????? Let me hasten to say that I am no great shakes as a mechanic, and you have taught me a ton about small engines! And your final result seems to be working well despite my machinist horror!

[@busterdee8228]

You sure know your way around those. I like the compact design. I was working at my dad's gas station when a carload of young women pulled in with a Canadien Pontiac (Chevy running gear). They asked why the car wouldn't go over 20. I asked if they had done anything to it around that time. 'No. Oh, we had trouble filling the transmission.' Where did you check it? They point to the tranny dipstick. What was the trouble? It didn't seem to fill up. [long pause] Oh, where were you filling it? They point to the engine filler cap. After draining 22 quarts of fluid from the engine (and doing an oil change), I assured them that their tenacity just turned the engine into a pump that was running too slowly to hurt itself. Seals were still fine, and the engine was now VERY clean. I suggested they not do that again.

[@Grisa77]

Nice view of the econoline at 11:30 . I miss seeing progress about it.

[@WhatTheTarnation.]

Love your videos and commentary. Thank you for allowing us to come along on your adventures. I noticed the green metal socket set you were using.. I said that it looks like a set of S&K's. It's not a brand one see's nowadays. When I was in high school, I worked at a Western Auto store and saved up my wages to purchase that brand of tools. They were not cheap.. It brings back at of good memories to see those S&K's. I suppose that's why I enjoy your content. It allows me to remember.

[@danaskubic2145]

Love my S&Ks., 1/4 &3/8 drive sets purchased about 50 years ago. Metric and American Standered with combination wrenches included. I did have to replace the tool box and the 1/2 inch wrench. Have a great day.

[@crossvilleboy]

I enjoy your videos and have learned quite a bit from you. There is always room for that. There are no crazy wild intros into them. No music. Just OJT that l need. And, you always express happiness when a machine fires up once again due to your efforts to save it, not junk it. l totally share that joy.

[@CharredSteak]

You're absolutely spot on, 180 degree crank offset is basically as smooth as you can get with a V4. Also has the perk of sounding like a mini-V8!

[@AllThingsMech]

Great vid as usual, Mustie...but brother, you absolutely have to support something as long as a crankshaft from both ends when turning it on a lathe - either with a live center in the tailstock, or on one of the bearing journals with a steady rest (if you have roller bearing fingers on the rest, of course). It's much safer for you, and that 10 thou of runout very well may have been corrected completely with both ends supported. It would've gone a long way in reducing the chatter too, along with some better HSS tooling rather than carbide. Anyway, no more soapbox preaching from me lol, just something to think about for next time.

[@unokarpa4405]

если длина обрабатываемой детали больше диаметра обрабатываемой детали более чем в два раза - тогда надо подпирать деталь упорным центром из задней бабки токарного станка.

[@bukka6697]

@@unokarpa4405 Translated for you, "If the length of the workpiece is more than twice the diameter of the workpiece, then it is necessary to prop up the part with a thrust center from the tailstock of the lathe."

[@darronsargent3956]

Wonderful video! Something that helps me contain a mess is setting the engine on a large cookie sheet while I'm tearing it apart. Then you can just dump into a bucket and it doesn't go all over the table

[@DonaldNickson]

I love your channel, I only found you about two weeks ago…I’ve gone back and watched😊 about every video you have uploaded. Great work Daren and I like it wen Bryan helps you, keep up the work.. I live in the Philippines

Thank you so much sir for going to the trouble of videoing all you do. I look forward every Sunday morning to see your new ones. You should have your own TV show as talented and smart and funny as you are. I really have seen every video you have EVER made on this channel. I`m a huge fan! Please keep doing what you do.

Governors are associated with the expression “balls to the wall” when the governor weights are full out. Sorry just had to say it. You are the man. Another great video!

[@echobeefpv8530]

Another great start to my Sunday. Loving this series, you are getting everything you can out of those engines !!

[@bobmillerick300]

Looking forward to next week. Same Bat time, same Bat channel.

[@stevenjohannesen88]

Wow what a treat for us viewers,to see something being turned on the lathe, shows us your engineering abilities, great stuff, cheers from Australia ❤️🦘🦘🦘

[@jamiekatz7591]

I'm so confused on this one. I'm not a mechanic but love to watch an engineer at work and to see the outcome. Can't wait!!

[@davidflamee]

Am really enjoying this project in the making and how you utilise these scrapped engines. Looking forward to seeing them burst into life.

[@thefirstcalled]

While it was really really painful to watch the lathe work, I enjoyed this video thoroughly! Thank you so very much for sharing all you do! Greatly appreciated!

[@tin2001]

I haven't got to that part yet, but I'm sure he probably did better than I would 🤣

[@jackieross3831]

I feel your pain brother going to try the same project in the upper peninsula of Michigan I was going to put the well in a different spot but since your video I'm going to put it down by a known water source in the winter didn't want to walk for water but I guess it's better than no water at all! Love the channel keep up the good work

[@letstalkaboutcars2998]

A fantastic way to start my day! Thank you for another superb video-really appreciate it

[@alexcrouse]

Time to tighten those lathe gibs! Pretty awesome final runout. Great work!

[@Mad-Duk_Machine_Werkes]

I was a head Mechanic/Shop Supervisor for a rather large Tree and Lawn Service in a former life. Lawn mowers quite often slide off a steep ditch, or into a water trap on a golf coarse, or off a sea wall into a lake or ocean. I'd say that second motor went swimming and they swapped it out under warranty or just because it was high-ish hours anyways- The watery oil- the White corrosion inside all the cyl fins, and MASSIVE rust and shit fucked up under the cast iron flywheel is the main suspects

[@Mad-Duk_Machine_Werkes]

Drill Bit TIPS are hard, the other end that you chuck on called the shank is SOFT the GIBS on the cross slide of your old tired lathe are loose as hell, you need to adjust the allen screws and get that tighter, also looks like the tool height was too high

[@johnmolnar2957]

Wow, Musti the machinist, using a yardstick for measurements LOL . looking forward to the rest of the build to see how it all works

[@lawrenceengel3330]

Mad machinist/mechanic projects are awesome 👌

[@williamhall4430]

A great idea !! It will be awesome to see what this Power Pack gets to benefit, maybe a Bilge Pump? Plenty of water to be moved. Nice turning skills on the Lathe as well. Always fun on a Sunday.

[@ericnelson6982]

I was thinking maybe you could drill the crankshaft. Then insert the piece of drill bit into the crankshaft to center it and also add some strength when it is welded.

[@gregholloway2656]

Absolutely. I kept telling Darren to pilot the 1/2” drill shank into the end of the crank, but he wasn’t listening 😂. Ensures concentricity and improves strength. The steady rest would have held the outboard end of the crank true as well.

[@jontebos7290]

i was hoping for that as well..😅

[@thomasflynn5366]

I was literally yelling this. I thought he had it when he held it up that way before cutting it.

[@ramblingman8992]

Exactly. Drill and tap end of crankshaft, then turn down and thread the end of the drill bit. Use loctite to stop everything coming loose during final assembly and job's a good 'un as they say.

[@bobuilt10]

I was screaming the same at the tv but Mustie must have had the volume turned down.😂

[@Ed-G]

Interesting video for Sunday morning. I'm surprised when you were attaching the second part of the coupler you didn't put the coupler in the oven and the shaft and the freezer to give you a little bit more tolerance. I did that pressing in a bearing on a motorcycle engine. Put the case in the oven and the bearing in the freezer. I was 12 working with dad and mom was not home😁

[@joeanonemouse]

What a fascinating build. This is the kind of stuff that makes me love your channel. Can't wait to see what you're going to do with the motors. Thank you Darren. 👍

[@gutshotgriz3936]

[@danaskubic2145]

Very interesting, looking forward to getting both engines operating together. Thanks for sharing Mustie.

[@vettekid3326]

As a former machinist that used to machine hardened material normally you would use ceramic inserts to cut it but since you were just cutting on the shank of the drill where it is not as hard as the cutting end you can and get by with just using carbide.

[@jonathanbuck6526]

Great idea, but Musties lathe is a bit under powered for indexable carbide inserts, you need at least 10 hp for those.

[@JT-tz5hp]

That crossslide and/or compound slide on your lathe needs the gib/gibs tightened up by the looks of it. And the saddle even. Basically check all the gibs. Also if you had welded on an oversized piece to begin with and then turned it down to size you would avoid all runout problems and pulling due to welding. Love seeing you get into a bit of machining. It'll really open doors for the stuff you are into. I remember that mill/lathe you had. Haven't seen that thing in a while.

[@PracticallyFixed]

Yep, remember the time he had getting that Bridgeport into the garage? It may be there forever. lol

[@danpags7023]

I would love to have a stash pile like yours. I noticed you were channeling your inner Curtis from CEE.. lol.

What fun you are having with all this little engine work and stuff like that. Your doing a great job of it!! You are soooo fun to interconnected with. All the best from Canada

[@stomper2582]

Once you get it mounted on a flat surface you can get some shim material and get the shafts tuned in closer. Good job with the machine work.

[@thedevilinthecircuit1414]

In many cases you can scrub the carbon ring off the top of the cylinder and then use a large Shop Vac hose on top of the piston to pull it out.

[@octane613]

Yeah but we all wanted to see inside the case anyway.

[@briantaylor9266]

Thanks for your videos. I'm not a machnist either. I would have taken a slightly different approach to extending that crank shaft, but your way got the job done too.

[@MRrwmac]

Mustie1, Somebody got excited and jumped ahead to couple the two together….haha. But, it was fun to see you build the coupler! Thanks!

[@ericdunn1255]

I have heard of people using muriatic acid to remove the aluminum from the steel on the crankshaft - my guess is that the crankshaft is reusable. New rods, new rings, and BAM! Perfect engine!!!!

G'day D man, greetings from down under. 🇦🇺 I do like the way your mind works. Can't wait to see how the 2 engines run together. As a side, I love the sound of your lathe, sounds like it's running on steam,😂 perhaps the gearbox needs some work?

[@mischef18]

Enjoying this project bro. Safe travels. Ken.

[@davidcoates4852]

Some motorcycles have a rubber doughnut/pretzel looking thing in the rear hub, just like that coupler of yours, between the sprocket and the wheel to absorb shock loading. I think it's called a cush drive.

[@TotoGuy-Original]

great video looking forward to further instalments and see what you end up doing with these 2 engines

[@paulhamilton4756]

Great video of hooking two motors together. Could you touch on alignment of the couplings. I worked in a refinery, and we did reverse alignment to really dial in the alignment and reduce vibration. They also have varying grades of rubber / phenolic couplers that would help with that rubber one coming apart. Thanks, keep the ingenuity coming!!!!!!!

[@merfan88]

A drilled Hole in the crankshaft for the extension, would make it more sturdy, and less dependant on the weld. Good job 👍

[@jasonbirch1182]

One of my favorite home made tools is a strap wrench oil filter wrench. I split a spark plug socket down most of the way and use a piece of ratchet strap in it. Any deep socket will work. Its great since you can put an extension in it to get a hard to get at filter.

[@pratt1bp]

That’s the chrome cylinder lining coming off Darren. Best to use the blown up block if the cylinder looks better on it. Seen too many home only to expose the cast engine block.

Cylinders are not chrome plated, they have a cast iron sleeve
