Got a question for Mark, Jacob, Lee, and all the other McGurus here:

Will a flywheel cover from a 'super series' engine such as a 790 fit and work on a S44A engine? I see the external profile of the cover on a S44A engine 'looks' like that of a 'super series' (compared to a 250 type cover).

Also, will a flywheel from a 200/250 work on a S44A without issue? Trying to help a guy convert a S44A to LH start...

Super series cover will work fine. My S44 has one. The D44 is different, but I think you could get one on it, but the plug is in a different spot for that one. Make sure it isn't a 125/101 airhorn cover or the starter engagement depth may not work. Flywheels are all the same on the saws.
 
Aaron,


I tried this on my 1-76, the 250 flywheel and the 1-76 flywheel were the same, aside from the pawls being there, or not there. Only issue when I put the LH start cover on was that the starter shaft was too short (+- .5 inch) It was unable to engage the pawls.


Then where the "hood" on the 1-76 is and where the spark plug cover is on the 250 starter needs some slight modification to work properly.


Been awhile here guys, internet was slow to get hooked up, I have been busy.

That's why it has been so queiet and peaceful here!!!:jester:

Thanks for checking flywheels and covers Chris. I'm surprised that the LH starter didn't reach on your 1-76. I did a 'trial fit' on my 790 and it worked. Was just under 1/16" shy of where the starter shaft sits (in relation to the flywheel) compared to my LH start saws. A fellow could space the starter pawl cup out with a washer and be right back there (if not just run it as-is). I don't have a McWelder IPL. I'd be interested to see if they used a different starter assembly or starter pawl cup than the 1-50/250/etc saws. Those engines are basically the same as a 1-76, 740, or 790) with the addition of a LH starter and a different carb and manifold. There's also a 2-man Mac saw that used the same engine as a 790 with the additon of a LH starter setup. My big concern is whether the super series flywheel cover (like what's on a 1-76 or 790) would fit on a S44A (since the other 80 and 87cc engines have a cover that won't work). Charles answered that...:cheers:

Thanks Charles! We're in business.:D

Progress on my garage

Here are some pics of my progress so far in my garage. I haven't finished the work bench yet. I did get my air compressor set up outside and hooked up. I mounted my filter and regulator under my work bench. Then ran a hose to my 50' reel. I like this set up good so far. I can angle the AC vent right at my work bench and never get hot working on saws. You can barely hear the compressor running outside with the AC running.

19 or 20...

First number is on the mark.

Yep, I'm still young and still learning.

Yep... you old (and some not as old) geezers have smacked me and kicked me all the way to the moon and back... many times... I needed it. Thanks!! :) I'm just glad it was verbal putting in place, rather than physical... I figure I might have had some broken bones and probably would be missing some teeth...

The guys at work (temp work at the same shop my dad works at, as I previously rambled about) liked me so much and liked my working habits on the panels for the overpasses, so they put me on a 60 ton press, showed me what I needed to do, and put me to work.

I was taking these 8" or so diameter flat flanges, which already have been drilled and tapped from previous processes, and slapping them into the die, then pressing them... to form a flange that will sit flush on the side of a water heater tank made by BW. Neat stuff. It would suck to have to use a bottle jack equipped shop press to do production runs of parts like this... not to mention none of the flanges would look like the other... they all would be bent inconsistently.

Made about half a bin (5 foot by 5 foot by 4 foot is the size of the steel bin) of them things yesterday. Started running the press at about 10:00 and left at 3:00. Talk about production, must've been about 3000 some pieces that I did. All I know is they are happy with my work... and I'm happy to be working. I assembled panels with another guy starting about 5:00 in the morning, and we stopped at about 9:00, since for some the shipping company wouldn't be able to ship them that day anyways. The press is fun to run, definitely a step above packing boxes and stuffing screens.

My dad says it is very rare for a temp to be put on a press... I figure I'm doing well. It probably helps that my pops works there too... and they all have mentioned that I work just as hard as he does, which means we are hard workers... When it comes to working, especially when it deals with getting paid, we work our ***** off, it runs in the blood. I was drenched in sweat just about every day I worked there this week.

Lenny says he has something for me Monday... not sure if he's talking about work, or work, lol. Either way, it should be something good.


Back to yellow and black talk...

I bucked up the remaining log with the Pro Mac 850. I did not get it stuck this time, which makes me happy. Also did not meet any nails or other foreign objects, which makes me happier. Best of all, she's broken in now, and is absolutely a bundle of fun to run... lookit those chips!!!

I raise you 1,450,000 chips... :D

Here are some pics to round off this post...

It's all in a pile waiting to be split...

Sounds a little rich in the cut.
 
Sounds a little rich in the cut.

The saw was recently filled up, I like it to run a little rich when full, then lean out... about half tank is perfect tune, in fact, it actually runs about the same for the remaining half tank until it's just about out of fuel... then it goes lean, very noticeably, and I let off the trigger, let her slow down and idle for a second, then shut her off and fill her up.

To have it tuned perfect on full, then lean, then go leaner yet... that is a bit uncomfortable to me. With where it is now, it pulls strong, then stronger, and when it gets low, it's very noticeable, rather than just a more monotonous leaning out sound... it's more of a sudden change from about perfect to lean.
I am just on the cautious side of things, doesn't really matter what I'm dealing with, I'm usually cautious...

I noticed that right away! Those things below your knees should stop the blade pretty quick if you get some wood pull and it gets away from you. Hopefully you did have your eyes and ears on.
 
Somebody show the shop monkey how to buck in the bind, so he doesn't embarrass us.

What did I do wrong, Emperor? Was I not supposed to get the saw stuck the very second time I've ever made a bucking cut?

Did I execute my cuts improperly? Was my mentor (my neighbor) not yelling at me enough and saying I am going to get stuck?

Everyone gets their saw stuck...

It's no big deal, unless another saw of another color has to cut them out... then it's a sin... for example, an orange pop cutting a creamsickle out... it ain't right. Never will be...

My neighbor showed me more ways to cut, like using the end of the bar to sever the fibers on the bottom of the log without hitting dirt, and using the top of the bar and making a nice rooster tail in the process. I'm learning a lot from him, and still got more to learn.

Keep at it.
When you can buck the bind, in a 40", without a wedge, we will promote you.

I kneeled for most of the cutting, and wore my steel toe Caterpillar boots.

As for wearing shorts, well jeans ain't gonna do #### for protection either... so it's kinda pointless there. Hot day today, shorts were a prerequisite.

I want to buy chaps just in case something were to go wrong, but my mom keeps saying "You're not a lumberjack." and #### like that. Guess what, many lumber jacks don't wear chaps... it's the average firewood cutter who does, and many of them have saved their legs from what could've been a very bad incident with those shiny and neat little cutters whizzing around the bar.

I'm going to get my dad to order them for me behind her back. I don't give a crap if she thinks it's a waste of my money. I think it's a good idea, since if something did happen, I should not have any gaping wounds and I won't have to take off work or school to recover, not to mention not having huge medical bills, etc. I am trying to explain to her, but sometimes she just doesn't get stuff. Either that, or she has ordered them behind my back... sometime she pulls crap like that on me too...

My glasses work well. Ears, well, I never heard worth a #### from the beginning!! :biggrinbounce2: Born deaf, very deaf in fact. Heard nothing below something like 90 some db's.

Left ear is still active. It takes things like McCullochs to get it to hear... :D

I'm hearing my 850 cutting in my left ear right now... I love the song. Cool thing is it doesn't hurt my ears, and ringing/tinnitus are nonexistent, well so far anyways.

Right ear has a cochlear implant. Pretty cool ####, it automatically cuts down sound levels above the preset 'pain' threshold. Also, I have no idea how the hell they get that little wire to go inside of the cochlea properly... it's really ####ing tiny. In other words, it was worth the pain and money of having the procedure done... yes, for a couple of weeks, the side of my head hurt, as in if someone had been kicking it repeatedly for several hours, or had hit the side of my head really hard with the side of a mini sledge hammer. Missing the big ass Vicodin scheduled intake by a mere hour resulted in pain... that happened fairly often due to napping which was a side effect of taking those Vicodin horse pills... I was doped up on that stuff... naps lasted hours and often made me miss the time to take the pill... and like I previously mentioned, that makes pain.
 
My brain's still drying out son...

I know... But you still gotta teach me more stuff!!! Don't dry out too much on me!!

I learned a lot from your recent post on the fancy 77 type Macs... I found it very fascinating, and your experience in that field is remarkable.
