Nothing but quality information from here! Really excited to see what this channel will evolve into!
Coming from a machinist, you know what you are talking about. I will have to copy your mandrel ideas. Thanks, love the channel.
Cool, now all I need is a lathe and a mill, 🤣🤣👍 but really thanks for the video, lot of great tips.
I’ve been playing with my glass “flat lap” and sandpaper and wood blocks for 10 years… yeah.., 30 thou definitely is a workout with the sandpaper!!!! I’m probably going to brake down and get the little $600 dollar harbor lathe… my old buddy with the killer machine shop croked on me last year unfortunately… they fantastic thing was I got to make a few of his Stihl’s run better over the years and he got to run one of my 350 hotrods when a large oak fell onto one of our wheelchair bound buddies and we went to take the tree off his house and get the hole covered for the winter…, old jimmy got me into the adaptive diving… when you get a chair bound person into the water and they are free’d and weightless in the water it a pretty awesome experience!!! We had Quads that would come play… it’s very heartwarming when you get to share those smiles!!!
Funny how a tool can bring so many together. Those memories are forever.
@@dynojoemods2764 😂😂😂😂. Yeah man! Looking back over the past 12 years or whatever it’s been since I got “seriously” into building and modding and looking back and LMFFAO about some of the crazy stuff I thought might be a good idea is pretty funny!!! You either need access or you need to buy and build a shop if you want to get into that upper level of engine building… I remember 10 years ago seeing that European guy with his different species of wood blocks on his homemade squish band cutter’s and thinking it’s possible to do this crap by hand…just can’t be in a huge hurry… what takes a 1/2 hour in a shop with a lathe…took me a solid month on my first husky 350 to 353…45mm flat top build but I’ll never get rid of that saw and I enjoy every single hour of rubbing those thou’s off and measuring then going back at it and measuring… and sanding and wishing that it was going faster…and then doing more sanding!!! LMFFAO!!! Best dang addiction I’ve ever found!!! 😂😂😂😂
needed this thanks my builds get stronger and stronger watching these
That is the goal. Show people multiple ways to build a saw.
That was VERY helpful! Exactly what I Needed. Thank you soooo much Joe!
Awesome video,I got a lot of ideas for my budget builds.One thing I was taught engine building was when using the glass sandpaper method of surfacing parts was to move the part in a figure 8 on the sandpaper to keep it even.
That will help for sure.
You're really rocking with these videos. I've seen Delrin mandrels used with success as well. Happy new year!
Very informative video, answered many questions i had thank you JOE!
excellent! thanks for sharing
What Clint thinks is this is a wonderful vid.
I've done 3 cylinders by the sanding method so far. The last had skirts, so I used the hole saw method.
I believe measuring a lot and keeping it clean is most important to get a good result.
Thanks for a great vid Joe.
Happy 2022.
Thank you Clint!
Measurements and cleanliness are super critical when spinning things in the bore.
Happy 2022 to you as well.
I've been sanding for years it socks but works..nice video👍👍happy new year
Gets the job done.
Happy New Year to you as well!
i remember when i was in shop class in high school cutting aluminum fun times
Brilliant video, I've watched a few on this topic and this answers a lot of questions. Really appreciated, putting out awesome content!
Thank you.
Hope it helps you dial in your craft.
Great Video Joe
Awesome video Joe 👍
I really liked this type of video is very interesting and informative. I'll try it out. Thanks GODSPEED
Great content. Keep ‘em coming. 😎👍
Cool video Joe very informative. Thanks for posting and Happy New Year
Thank you, happy New Year as well
Joe
This is the one of the best video you’ve made to date!!
Almost anyone can do this !!
So therefore it will be beneficial to the masses that would want to do this to there saws!!
God bless and have a blesses New Year!
Love to come and see you sometime
I’m south of Ft Wayne a bit so probably 2-1/2 hr drive, not too bad.
Thank you,
Andy Jones
Thank you.
Really appreciate that. If you are headed north let me know.
Very cool! Thanks for sharing!
Hope it was helpful.
Thank you for watching.
Just for giggles I drilled a hole into the upper transfer from the outside of the cylinder...used a 1\8" carbide hog on a Dremel to raise the roof of the upper transfer..from the outside in..then tigged up the hole. No 90° grinder?..make do. Long hog through the lower cleans up the weld.
That will for sure get the job done too. More than a few ways to get things done. That is what makes it the most fun.
Nice video! 👍
Excellent, I aways learn something from your videos. Love the technical how to stuff. Would like to learn more about 2 stroke performance theory and what kind of a wrinkle strato ports throw into the mix.
I really like to hear that.
I will try to incorporate some more of my thoughts in the build process.
Joe you should spruce things up a bit with an intro music etc.... it's just the way things are these days and what youtube has evolved into. Needless to say you have great content but it is what it is and people want a nice polishe finished product nowadays. Keep it up really enjoy watching what you bring to the table 😀
That's exactly how my builder does it 👍
Thanks this helps a lot
If you drill a hole in a spade bit or use a torch to punch a hole you can use an aftermarket piston with sandpaper glued on its roof and an old piston pin… spinning it with a drill… sanding the bands and whatnot… you can make a wood jig that you can chuck and get a piston pin and spin your piston…
Thanks Joe, always the best. Here I thot we were going to stick a piece of sandpaper to an old scored piston !!! Happy New Year. Keep up the good work.
Thank you.
That method works too.
LOL…. No chit. That would be by hand……. Wouldn’t exactly call a full size lathe, “by hand………”
Man Joe
I knew there had to be a way to do that riding on the bore!
Great info!
🤝🤝🤝
Thank you. Hope it is helpful to some saw builders.
Good job 👍
Thank you
nice i like it well done
Thank you
Hi Joe just found you channel and its a gold mine! I would like to know the main purpose of cutting the squish, I heard about cutting the base te reduce it but what is the benefit of reshaping? Thank you and keep up the great work!
Cutting squish reduces the combustion chamber size raising the compression. Also allows you to cut the base even further to move the ports around. Some saws perform better with a lower exhaust and a bit more intake duration
Great vid I need to up grade to a cuter like that I'm still doing it with sticky sand paper works just slow an has a higher risk factor
1/4" square piece of hss really helps to remove the bulk of the material. And can grind them for even better removal.
Nice job Joe, what is the reason for cutting the squish and base. Is that so you don't have to cut so much off the base so doesn't lower ports so much or matching to the piston etc? Sorry if that is a dumb question 😂
If swapping pistons, or reducing the size of the combustion chamber for more compression and lowering the ports. Some saws benefit from a lower and wider exhaust port.
I’ve seen people lift the squish band and then go in and cut the base.
Is the reason for this that they are trying to lower the exhaust port to gain compression?
If you don’t need to cut the squish band because of a gasket delete, would you still consider doing it because of the timing changes?
Aaah crap, only a hobbyist and now I want a mill!!
I may need an intervention. 😂
Sorry not much help here... Everyone needs a mill. Can double as a coffee table if you need a good excuse
@@dynojoemods2764 I’ll try that! Wife might not notice a coffee table! 😂
Really like watching your videos you do some really awesome jobs really interested in to scrub stuff always have been keep posting the videos like to see more have you ever done anything with the ms380
Never seen a 380 before. Sorry.
Stihl ms380
I don’t have a lathe so I make my mandrels out of old pistons
Piston will work too
When sanding on the base what grit sandpaper would you use ?. That sounds like it would take a good while!!
60-80 grit if you are taking .020" or more off. Then finish with 240-320. Leave .005-.010" to smooth out the deep gouged from the rough grit.
Really good video like you said hate to sand 20, 30 thou but hey do what you gotta do to get the numbers
Thank you.
That is what it is all about. Building saws they way you can.
How does this help unless using a taller piston? If you did this to a cylinder and used stock height piston it would lower compression and would lose power!
Remove the gasket or cut the base on a lathe. Some saws the piston will hit the head without a gasket. So you can drop the cylinder and cut the chamber to increase the compression
Forgive my ignorance but doesn’t machining like this require some modicum of cutting oil?
Some oil may help, but this works out pretty well.
When are we going to start doing SAS on GMT400's and stuff?
That does sound fun... might just be a Gmt 400, 305 to turbocharged 454 swap though...
@@dynojoemods2764 potato pototo. I just want to see a proper smokey burnout.
@@NCSU4x4 Prolly plenty smokey just starting the old 305... It has been a while.
@@dynojoemods2764 well... since we have gotten to cold start / old start season can we get a video??
What does one of these “Dyno Joe” squish band cutters in 52mm cost me?
Still working on that part
@@dynojoemods2764 well get on brother!!! You’re out there on the forefront leading the charge!!! To help the rest of us chainsaw addicks… make gains that don’t have a machine shop!!! LMFFAO!!! Just joshin’!!! It really awesome that you have started your channel and are sharing all this awesome footage of the dyno runs and all this stuff…! I’ve been thinking about you’re angle finder degree wheel but I really use the counting on my wheel to kinda see what an engine is doing…if that makes any sense.,. Until I really started using Kenzie’s Bayou County’s port mapping on paper to see the engine… I wasn’t really seeing everything that I needed to.., 😂👍
@@dynojoemods2764 opportunity is knocking. Congrats Joe. Hope this venture continues to take off for ya.
Glad you did a video on this. Something i get asked about a lot. Really no excuse for people not doing at least some machine work.
Yeh, lots of ways to lower a cylinder. Just Hope it helps get people thinking, or shows them a way to get it done.
@@dynojoemods2764 right on. Hopefully people start to realize building saws isn’t as easy as just grinding on cylinders too
You still have any kits available joe?
Yes, they are listed on the website.
@@dynojoemods2764 thanks I ended up answering my question after haha typical..
where do you get the cutter for the mandrel
That is a 1/4" hss lathe tool
@@dynojoemods2764 thanks
Can you make one/some for me? Or buy your old ones. I need an entire set with many size bores
Cutting squish without a lathe?
Takes some time, but it is possible to get decent results with a mandrel
@@dynojoemods2764 without any way to make a mandrel is it still possible? I’m looking for ideas for my hobby
Sweet 👍 video Dyno Joe ... have you priced aluminum round stock lately? Holy smoly has metal gotten expensive! I was at the local greasy spoon having breakfast and conversing with the owner of Southtowns Welding and Fab. He told me a sheet of stainless is almost 2x as much as last year. Stock up now gents
Thank you.
Material costs are something else that is for sure. I noticed my deflector material jumped up pretty good too.
@@dynojoemods2764 Biden-omics at its finest 😁
first comment
continually converting from imperial to metric.... you Americans ........sigh
25.4 is my favorite conversion when dealing with these saws. Never have done much with metric in my career. All of my measuring tools are imperial. Just second nature converting everything.
@@dynojoemods2764 i know what your saying... at 70 years old i went through that transition.... but everything based on '10' make life so much easier
