Mcculloch Pro Mac 850 pipe. Will a shorter pipe make more power??

[@THEMOWERMEDIC1]

Brings back Memories of working at the mac dealer in my teens and 20’s. Loads of 10-10 and 700 promac’s have seen my bench. Love the channel keep it up!!

[@BuckinBillyRaySmith]

ya look happy young fella .. you should be .. ya done good that thing sounds happy too

[@SuperJamster1]

Does tuning it without the chain and bar on make any difference? Love these two channels.

[@stuartramage5933]

U getting there tinman. She sounds lovely. Awesomeness Stuart

[@thebradleysoncatbirdhill6849]

I truly love how you take us through every step of the process as if we are doing it ourselves, stopping and pausing along the way to check and reassess and make new plans. You are an outstanding teacher, as I have said before! 💪👍

[@tinmanssaws]

Thanks buddy!!! You're making me blush!!

[@caseycarpenter7043]

Saw sounds strong and snappy good job

[@aaronpowell4885]

That pipe came out slick👍 and with the great rightnow response! I bet she'll eat.

[@robertgreenia1874]

Love watching u Donny walker Buckin iron horse thanks it helps me sometimes stay positive I just had sell my Stihl 044 my 930 jonsered my husky I heat my house with wood I'm little older little disabled my health not best if ur like me I love my saws they mean lot me hard me to sell them but I had pay my property taxes been hard this year it bother s me lot that I sold them but then I watch ur guys video s and made me feel lot better change my attitude so I say my self I can buy another used older saw sometime so anyway just want say thank you all for videos and subscribers love video s thank you

[@waynethedukelamont2078]

I can’t wait to see how it does in wood, it definitely sounds better, you’re getting closer, needs something, but not sure what it is, maybe a little larger on the end of the pipe instead of necking it down like it is.

[@michelpicton8357]

More echo videos 🤤 your videos are awesome Tinman hello from portage Manitoba!!!

[@chrispaul1326]

Tinman watching you beat the curve on Macs prompted me to buy a 10-10. I have big saws well enough. Might try a lil red barn p/c to port on. Grand old workhorse you tinkered there... Rock on.

[@Redneck-Redemption]

I spent all day watching every video on the Mac. My family has been cutting for over 70 years around the place I live. I have always like finding old saws, doesn't matter the shape, I rat holed them away. Recently my cousin and I had the opportunity to set up a shop to play in. We did our first teardown on a Stihl ms310 last week that was cold seized and I have been researching what brand of top end kit to go with. I'm leaning towards the Meteor. But a do have quite a few saws I've collected I want to get running. I like the older ones much better than the new ones. My Stihl ms250 is my newest and because of the problems I've had with it, will probably be the last new I ever buy. The ones I am going to get running that need small parts like ignition and covers are Jonsered 2031, 2077, 2083, 2094. Stihl 08 S, 056 AV, 031. Mac saws I have a few but never paid attention to what they are. Now that I know what you are playing with I'm going to dig through the 55 gallon barrel of Mack parts I have collected and see if there's and parts you can use.

[@jeffkenyon7084]

18 k congrats I find I click on your videos before buckens now good stuff

[@sebastianleicht]

Nice pipe, Tinman! You don't have to excuse for your welding! This thin Material with an mma /stickwelder (and depending to the sound an AC-Maschine I guess) is not easy! You're doing well!

[@simpleman4224]

That jewel is snappy! Great job! Congrats again buddy! 👍👍👍👍🇺🇸🇺🇸🇺🇸🇺🇸🙏🙏🙏🙏

[@tommymohlen8919]

Cobgratulations on 18k Sir! I just found you the other day but ive really been enjoying it so far, thank you for sharing with us! 🍻

[@tinmanssaws]

Welcome Tommy

[@patthesoundguy]

You essentially made a short header chamber. It's awesome. From my two stroke scooter tuning experiments years ago, I came to find that the length of the header really affects where the torque curve starts. Too long of a header and the torque comes in way too high in rpms. As soon as I saw the finished pipe I knew you probably got it right where you wanted it. Great welds on that pipe, if you can weld those pipes like you are doing with that stick welder you can weld anything!!! Superb job my friend! 👍👍👍

[@Peter_Gunn]

It looks like your getting er done. Amazing what all you can do with a saw

[@mrxlh]

Nice job with just a stick Tinman, for years that’s all I had and was able to weld some really thin stuff with practice and patience. Stick machines are really low overhead too, no gas or extremely spendy filler metal and consumables. I will say though, there is nothing like welding in shorts and flip flops due to no sparks with Tig.

[@tazman-kennyfuller]

Oh heck yeah Tinman. Nice work friend. I can't wait to see er in the wood. You got the Crack can't wait to see the Pull. Love ya Brother. 🌲❤🌲✊🪓

[@rncboy2]

That sound you are talking about you can feel it for sure when the pipe is right. Love it Tinman buddy awesome work!

[@chuckuu9294]

Great job on the pipe. Made it sound nasty.

[@DaveyBlue32]

Trying to remember the old Mr. Mac-attack’s research... 70-80cc engine was 3 1/2” and 51/2” pipe length...straight pipe that would create a pulling effect with the exhaust resonating due to the sound waves....

[@johncoleman2495]

The Tinman needs a small mig! Eastwood sells a nice little 110v cheap.... perfect for thin wall material like that....

[@jensenwilliam5434]

Thank you .

[@markssmallengines3542]

What would be cool is utilizing the original muffler side cylinder mount bolt holes and making a nameplate with buckin billy ray on it 👌 I personally would be making them a extra side mounting point too. its possible it could be dropped on its side or hung up on something. Can't wait to see her ran in and ripping great work Tinman 💪

[@rossgraveley]

Sounds great 👍👍 good job

[@Alan_Hans__]

There's 2 things that I've seen recently that are probably worth you having a look at. The welding style colloquially called "Texas tig" works brilliant for welling on thin section pipe when all you have is a stick welder. It also allows you to fill gaps that you never could normally. The other thing is a brilliant tool. A needle scaler/descaler strips welding slag off something amazing.

[@pm270100]

mate you need a gum tree to test it sounds goooood

[@tinmanssaws]

Mail me 3 footer mate!!!

[@edwinladshow5791]

I also stick welded an ironhorse muffler.I used a 3/32 1/16 and 1mm 6013 stick.Nice work on the Muffler!!

[@sagebrushhillbilly4655]

Nice job on the welds, brother. Small and thin projects like that can be tedious. There is a NOTICEABLE difference between the first pipe and this one! Way to keep pushing and put in the work!

[@neilcurtis2741]

Nice job She sounds pretty wicked!

[@AnDrEw122100]

The old trusty felt marker . Lol good job buddy.

[@Hydrogenblonde]

Hi Tinman, you are doing really well with that stick welder on that exhaust tube. But if you get another welder don't get a MIG get a TIG. A TIG has much better control for thin metal like tubes and sheetmetal. It is a little bit like OXY welding feeding the filler rod by hand but with the power of electric. Alot of people buy MIGs because everyone else has got one but really they are not that good for one off work like you are doing. MIG was invented for production work where manually feeding the filler wire would be a pain, the big rolls of MIG wire last a long time also removing the need for changing filler wire during a production run. But that is not a problem on the bench making one off things. Believe me you need a tig, you will never look back.

[@tinmanssaws]

Morning, tigs are great for sure.

[@jeffreyrubish347]

Great job on the pipe!

[@timgordon6160]

I like what you did bud!! Sounds great! Less is more sometimes!! Have a great weekend Tinman!

[@justinweaver8787]

Snappier i like it

[@thomaskapetantsis4951]

I love watching your videos and have learned and tried certain things but I have a question, where can I reach you at???

[@johnsonlong1272]

Congrats TinMan on the sub numbers! Question for you this is just for fun I have a curbside throw away weed eater engine 20 cc's I have had it running now and put a timing wheel on it. Here are my numbers> .025 squish exhaust 110 degrees Transfers 135 degrees Intake 60 degrees So that's what 25° blowdown ----------------------------------------------- Obviously I'm going to clean up the ports and probably widen them out. Also I will build a pipe borla exhaust to rid myself of the ridiculous EPA muffler it has on it in the name of science of course lol. This is piston ported no reeds and just for fun I have a lot of these to play with they came to me as curbside junk I picked up to practice on. I would greatly appreciate it if you would give me some safe mild side go fast numbers and then some more radical numbers. remember if she grenades I'm out nothing other than time of porting maybe some worn out bits. Maybe I should have made a pre video of stock and put my tack on it to see what the RPMs were stock. But I have already tore it down to Port it. So maybe on the next one I make a stock running video and check RPMs. My end goal here is to Port power saws. But I figured why not learn a little on some throwaway weed eaters.

[@joescott803]

How would brazen them work. That’s pretty easy to do

[@rogerford4427]

Nice build. 🤙

[@gundysgarage6664]

👍 she sounds awesome!

[@Piledriver2235]

Sounds great! Get it in the wood!

[@stevetheriault4164]

SOUNDS GREAT NOW SHE JUST NEEDS A KICKSTART LOL GREAT JOB ON THOSE WELDS BUILDING THAT PIPE BE SAFE TINMAN WELCOME TO ALL NEW COMERS

[@tomnielsen6439]

I would have used an acetylene torch with the welding tip and a coat hanger on that. Or a tig welder.

[@BigMeepsadventures]

What size pipe would you recommend for a stock sp125?

[@thesmallwoodlot433]

Great saw, can’t wait to see it in some wood!

[@surefire650]

Wheres yer mask brah?😂Jk thanks for your work.

[@timberray9572]

Have you ever thought of a venturi style muffler? Big pipe necking down and then going big again. Just something I have wondered about, I am not a saw builder but I do tinker on them.

[@tinmanssaws]

That may be an idea. Thats the fun of this stuff, theres no right or wrong when you're doing experiments.

[@fabzacres-blackcat]

I’ve come here to chew bubblegum and kick ass ... and I’m all outta bubblegum! Looks like ya fabricated a “Rowdy” Roddy Piper .... muhahahahaha

[@tomv7552]

Should be using a TIG you’ll get much nicer welds once you are proficient. At the very least a mig

[@MinusTheSparkPlugs]

I'd say for stuff like that you should get a TIG welder with a foot pedal (to match the foredom with a foot pedal lol)

[@sanchezzz1]

wow can you ever hear the difference with this pipe.

[@tinmanssaws]

She seems to have woken up from what I can tell

[@vtecpowersaw1577]

Welding that thin with stick welder u cant burn for to long blow a hole straight through it. Migs are a little easyer. .ive made a few pipes one desine stands out the way it pulls . Ial haft to film it

[@yrdGBA]

Did they make a full wrap handle for a 250

[@JacksonHall611]

If you are talking about the Mac 250 reed valve yes they did it is the same as 200, 380, 450, 550 and quite a few others

[@robertsmith7580]

Should you be concerned about shooting the hot exhaust towards the bar potentially getting the bar and chain to hot !

[@JoeRainis156]

She’s Peppy EH!
