- Come along while I reposition the bearing pockets in a clamshell chainsaw engine; we have successfully moved the pockets in various OTHER ways: by hand, on a lathe, and now we are using a mini-mill.

Good video! You kind of put me in mind of myself...in a way...tinkering the hours away, which I do lots, usually yields benefits. Makes a man think. Keeps him sharp😅. Always a pleasure watching and learning from you. Thanks again.
@bigmoustacheal3295 Tinkering is a pretty dang fine past time; the ol "Idle hands" chiche comes to mind. Thanks for riding along!!
Brilliant! way more patience than me
@joecasatelli4825 Thanks Joe!! If it wasn't "just a hobby", the time could sure be considered "wasted", couldn't it??!!
This is just fantastic.. Yes Sir this is great content. Just love the will to make it happen. Regardless of setup time and how frustrating it can get sometimes. Kick a$$ vid
@Houseworksaws Thanks Matt!! Hopefully it will give the people some ideas for the cheap saw shootout!! The set-up really isn't too bad once the fixture and my measuring/cutting tools are made; I ain't saying I would do it for a full time job, but for a hobby/fun, it's rewarding!! Thanks for the kind words!!
👍good job friend
@pastormike5054 Thank you Sir!! Thanks for what (I can assume) you do, too!!!!
👍👍 very creative- nice outcome. Love it when a plan comes together.
@crazyfeller5704 I have tried it a couple of different ways; my hand and with a mill; both are doable, but this is my favorite so far. Like you, I love a good outcome to a plan. As often as not, I'm "driving" my plan down the road and see my left rear tire pass me up!! 🙄🤯
Awesome execution of a plan. But I also know the feeling of seeing your tire pass u up as well I’ve drove that train a few times in my life. 😂
@JackScott-v2y Like I often say: "#1, you gotta have a plan; #2... not all plans are good plans"!! In this case, a blind hog will find an acorn every once in a while and it worked!! Thanks for stopping in and joining-in; it's the first I remember you commenting here... welcome sir!!
Nice work and looks like you needed some patience with that 👍
@sunbear1973 Oh, it ain't too bad; just go at it like a pigmy eats and elephant... one bite at a time!!
Really enjoyed this one 👍
@fearghalmorrissey2601 Awesome!! Hope it gave you some nasty ideas!!
Hay chaff hope ya'll are well I have nothing to add as I don't mess with clam shell saws but thanks for sharin' your ideas with us. stay warm fren.
@tomintexas817 Well, I thank you for stopping in... even is clamshells aren't your cup of tea! Being a cheap hack, I sure like them and the challenges they give me. Mostly, the saws are cheap and the parts are cheaper; so therefore, mistakes are also less "ouchy"!! Staying warm here!! It's -3F right now; supposed to almost make it to just-freezing tomorrow; may go out and get a sun tan!!
Another fine and interesting video Mark! I just love the VooDoo you do. I am so amazed at your practical ingenuity. I have a mini mill and lathe and could do the very same thing, only the scenario would be different. I would buy all the tooling, spend hundreds of dollars only to find in the end I need more. You have made your tooling and it worked a treat. Fine example of ingenuity and craftsmanship. Great work my Friend!
@markmetzger5430 You're sure right about the "in for a dime; in for a dollar" type of thing!! You're sure right; if a person had to buy the angle iron, that alone could be a coin or three; the angle iron, some bolts, and a piece of hss cutter were about the only thing I used...other than the machines... Oh, AND dial indicators, lathe tooling to make the tools, drill bits to make the tools, more dial indicators for setup, bench grinder to sharpen the cutters, more dial indicators, magnets to hold them, another longer dial indicator, welder to make the fixture, , a short dial indicator, plasma cutter (or grinder/cutoff wheel) to make the fixture, ... holy crap... Just owning the machines won't get us very far, will it??!! 🥺
Thanks for stopping in Mark; hope I gave some ideas of what a man can do with his little tools!!
@@HayChaffandSawdust1 You gave me some Ideas and the courage to try this without buying hundreds of dollars worth of tooling to accomplish it. An average man can do much with little. I see it more as a creative exercise to accomplish results like yours using my talent and brains instead of my wallet ( which is mostly empty 😁) Good stuff, be sure!
Turned out good . I was worried your chuck might have come loose. Just shows you can get it tight with your chuck key trick.
@jaysparrowhawk9388 Thank ya Sir!! That chuck key is the bee's knees!! You can sure put the uumph to it!!
Wye hello moonshine.I bought a Jonesered 2255 for 65 bucks a few years ago, and the chain break was stuck, so I removed it an i opened up the muffler, cranked the oiler wide open and modded a 28inch bar on it. I've cut alot of 2ft sized trees with it. Those 455s have pretty good power for a cheap saw but I'd like to see how good one can be. Thanks for doing all this tormenting yourself in the process of learning and teaching.
@itllkeal We might leave a little dust in the corners and under the rug, but I think we will chase the gains pretty dIligently while still trying to retain a GOOD and RELIABLE work saw. I sure don't mind tormenting myself a little with this saw; I think the power/weight ratio could be a LOT better. Thanks for stopping in Sunshine!! Temps here are about 3 deg and about 15-20 below with wind; but, it IS sunny, so it ain't too dang bad!!
Was just going through utube and boom, my favorite channel!!
You have a ton of videos to catch up. I have been trying, haven’t been able to so far, but working on it 😂
@alltherpm What a day!!! I came inside to check the comments and THERE you were too!! Looks like we are BOTH winners...!
@wrstew1272 Right here and right now, the weather ain't fit to do much else!! I need to cut bearing pockets in the Poulan, but my Dial indicators are sliding SOOO sluggishly in the cold that I can't dial-in anything. We are in the single digits (from a few below at night to a few above during the day. I'm sure glad we use Fahrenheit...it's 3 above right now; if we were using Celsius, we would be -16 and negative 16 is just too dang cold!! 😉🤯
@HayChaffandSawdust1 same here, it's 5 above right now, cutting bearing pockets is awesome stuff, got one id like to cut too! I bet ur running around trying to keep water from becoming a solid!!! Stay warm!!
Nice work
@jeffdillard8789 Thanks Jeff!!
Good stuff.
@TheGreasyShopRag Thanks Scott!! I sure could have used YOUR whiskers this week!! -3F right now; not much getting done here besides catching up on editing!!
@@HayChaffandSawdust1 Brrr. We just went through that cold spell. Warmed up nicely to 9 degrees this morning.
Fascinating! Thank you Sir!
@mattw5729 YOu're welcome and thank you for the encouraging words!!
Fantastic work love it!
@jonathanhensley8685 Thanks!! Of course, after jabbering with you over the past week or so, I've sure been thinking about other options to make power!! Add 'em all together, I guess!!
Excellent video/content! This is definitely "gettin 'er done"!
A 'test indicator' would make life easier for direct measurement on lining up on the pockets- Although indirect (on a test bar, as others have mentioned) might be easier yet (after you've made the bar).
Keep the awesome content coming & thanks!
P.S- Saw that empty CC fifth hiding back there again- 😉
@ls2005019227 Rob, thanks for the input on set-up!! Good eye on knowing that is and EMPTY one... a keen eye sees a little dust and knows it's a retired soldier!! My currently-enlisted ones don't get much dust!! 😉
It'd be nice if someone produced taller pistons that could be machined to desired squish etc.
@jimholz1102 It sure would, wouldn't it??!! About the only drawback MIGHT be the additional weight... but we could sure fix that couldn't we??!!
Parallax is the word that you were looking for 😅. Great concept, been looking for how you cut them, now I need a mill. And more dial indicators. And arbors. Damn, she ain’t gonna be happy (again) 😊
@wrstew1272 Dagnabbit!! I don't need to be in Dutch with my wife AND yours!!!
You make it look easy, but I'm sure that cut took some experience to set up. Well above my pay grade!
@Kevin.L_ Making it look easy is all in the editing 😉😂 On this particular experiment, I had to substitute will-power and determination for Experience!! I was far more happy with these results than the 029 I did by-hand a few months ago. Hope it's not too cold in your "air conditioned city".
@HayChaffandSawdust1 it broke 10F today so that's an improvement.
Will power and determination seem to be in good supply in your shop .
Thank you for the video
@richardwarn3706 You're welcome Richard; thank YOU for making me want to share the videos!!
Fun video. Stay warm young fella it's 23 below zero here this morning.
From one old coger to another, another log, or three 😂.
@oldcodger1929 That's too many BELOW!! Been in single digits F here (either a little about or below a little) with windchills far into the neg temps. Been doing my best with my remote hog waterers; no electric or running water within 1/4 mile, so plenty of time trying to keep my ol antiquated propane hog water deicer burning; propane keeps quit gasifying, I think!! I'm JUST far enough south that they use butane in the propane (I think); it stops gasifying at a much higher temp than propane. Aw heck, there I go rambling again!!
Keep your ears tucked in Old Codger!!
Another interesting video, thanks
@sawnut Thanks Sawnut!!
Boy, that sure is slick, and despite all the set up, it looks easier than doing it by hand.. as always, thanks for sharing, stay warm!
@Archer_82 Yes sir, I think it's well worth the extra effort of set-up. You know all too well about my next point... it made getting the correct clamp force on the bearings FAR easier. I still like your method; I just directed a fellow to the series yesterday!!
@@HayChaffandSawdust1 outstanding, I hope more people realize they, as well, are capable of these modifications.Patience, and some basic hand tools, a rotary tool and a vice. Both the 021 and 025 made it through firewood season without having to be cracked open.
I’d like to see the list of rules you are working around, for this clamshell challenge. Not planning on entering anything myself, just curiosity.
@Archer_82 i think the rules are VERY open; plastic case, clamshell engine, and 64cc max. The fly in the ointment is the fact that it's a "claims race"... anyone (other competitors) can buy the saw for $200 after the competition... if you're not willing to let your saw go for $200, then don't race it. Can run race chain, run on a nitro bottle, on nitromethane, can have an expansion pipe, etc... just whatever you are willing to sell for $200. This particular saw will not be for the competition; these 455s and ms290-390s bring ~$300 here STOCK. Got a poulan that I think we will work-on; brand new condition, those are going for ~$75 here in almost new condition.
That was some achievement, from idea, to set up, to completion. Under the circumstances of what you got to work with. Was wondering how you planned on matching the the lower pocket until you said.So 7tho off the pocket is equal to 7tho of the mating surface. Genuis.
@nickywalsh8492 Thanks Nicky!! I think the video if it running (spoiler... it does run great) will be in a week or two; thanks for coming along and joining in!!
A fixture with a removable ground rod that fits the pockets is a simple way to dial it in.
@RichFife It sure would be. Between the Ms250-types, the MS290-types, the Poulan, and the Husky, there are so many different bearing and seal sizes that the drop gauge seemed most economical; there are three sizes on the Husky 455 to center; of course the seal pocket and the outer lip are far more forgiving.
@HayChaffandSawdust1 with that bit of knowledge, you could make the rod to the smallest of diameters and make sleeves with a close slip fit that'll allow for proper alignment. Downside is, it's a lot of detail work upfront.... upside is, if you do them often, you'll save time later.
Love the videos man!
IF you’re doing lotsa cylinders production-wise , you could just make a jig instead Fife
😉… This here method works just fine for taking light cuts of .002 - .003. The only thing that I question is the deflection from the top pocket to the bottom - depends how the spindle is (rigid/sloppy). Be easy nuff to check once the cuts are made - just thinking out loud here.
@fabzacres-blackcat well no shit, he just showed everyone that it works just fine fabz. 😆 there ya go again stating and repeating what's been said. Ahahaha
I'm not a fan of clamshell saws... I monkied around with a few.... the last one I did, I machined enough from the mating surfaces to where I could use a gasket... that was a fun endeavor. As far as I know, that saw is still out there cutting tops... downside is, if something happens, there is no replacement.
@RichFife I sure get it!! With me, I'm about like flatulence in a tornado; I'm never anywhere very long; this will probably be the only 455 I ever do. I'm dong a Poulan 5020 right now and THAT will probably be the only one of those that I ever do. I might want to consider your suggestion for MS250 and MS290 chassis though!! Sure appreciate the ideas and banter!!
Could the top of the pot be sliced of and bolted back on a bit lower ?
@SepticWhelk It sure could!! This particular "build" will be a normal firewood build which I may send down the road; for that reason alone, the two-piece head didn't make sense on this one. I think the gains from a two-piece head has WAY more potential for a play saw or a saw that will only break down on ME. Thank for joining-in and mentioning the other option(s). Love the exchange of ideas here!!!
If you want to make some cash doing this I'll send you a 455 cylinder to cut the pockets on. Let me know what is worth?
