It's people like you that make KZbin great! Thanks:))

[@SoatMon]

Wow, Thanks Thomas!

[@robertwegner9369]

My skil 77 has the metal handle. Circa 1971, and works great to this day. It’s a gem and not the type of saw you mishandle and abuse. Thanks for the info. It was helpful.

[@SoatMon]

They are great saws!

[@robertwegner9369]

I bought my skil 77 in 1971, 53 years ago. Great saw for structural framing and deck building as well. Only parts I’ve replaced are the cord, brushes, and foot after one of my carpenters dropped it from a roof we were framing. Thanks for the instructional demonstration as I had a problem with excessive sparking. Thought I needed an armature but cleaned the parts up and installed new brushes. Also when it was disassembled washer springs fell out, but followed your video which was very helpful. Thanks

[@SoatMon]

You are very welcome. Thank you for letting me know it was helpful.

[@ToddAndrewCole]

Hi Soat! I've watched quite a few Skilsaw repair videos in hopes that I will remember how to get mine back together, and I really appreciate the excellence of your video, your thoroughness, and the straight-forward way you explain things. I hope you are having a pleasant day. Thank you for the video. Take care.

[@SoatMon]

Thank you for your kind words and letting me know. If you have any trouble check out this video it will help you. kzbin.info/www/bejne/l5-aZHeni82Me5Y It's not mine but it helped me.

[@estebanflores8049]

this was the best video I've seen that breaks down the main parts of this saw: the electrical components! thank you for this video. I just bought a saw like this one and one thing I noticed was that there was a lot of build up of saw dust and oil and goo all around it. Cleaned it up and noticed it had next to no oil in it. Refilled but I do see some sparking. Not as much as yours did, but I may need to replace the armature later. I hope the worm drive is still in good shape.

[@SoatMon]

You will always see some sparking. I bet yours is fine. They are awesome saws, take care of it and it will last a lifetime. Great buy!

[@carlosgavino6874]

Old video still worth it's time in gold helped me tremendously with my shd mag77 I received from my boss it was best up but still ripping and cutting green and pine like its paper that l you

Good to hear

Ça a été un vrai plaisir voir comment vous respectez votre outil. Il s'agit d'une magnifique scie circulaire. Je viens d'acheter la mienne et j'espère qu'elle va m'accompagner jusqu'au fin de ma vie utile.

[@PartScavenger]

Ah!!! It even sounds right! I love that saw so many good memories of us building stuff.

I had my skils saw for over 24 years still working fine like a champ 💪🏼💪🏼👍👍

[@rightlanehog3151]

Thanks for taking the time to make this video. I have a bunch of these that need varying levels of maintenance/repair/rescue/resuscitation/divine intervention 😉😂

[@SoatMon]

Awesome, I'm jealous.

[@rightlanehog3151]

@@SoatMon Please don't be jealous. In the last couple of years I have started a 'home' for unwanted and neglected old power tools. Videos like yours will educate me and hopefully pave the way for their future rehabilitation and possible return to a productive existence.

[@steray8112]

Super professional, clear, quick video. Bought a mag77 in a garage sale for $20, barely works, and think I might fix it now. But I'll probably buy a Makita hypoid on eBay just to be equipped.

[@SoatMon]

Good luck with your repair!

[@treverpudwill5797]

Great video! Thank you so much. i have that same saw and will be fixing it

[@glennfelpel9785]

It was both helpful and interesting. And I know exactly how you feel about your saw, they become a part of your project personality. We have an old all metal porter-cable saw and wouldn't want to be without it. But it isn't a worm drive, the direct drive style. Why do you like the worm drive type? I have never gotten accustomed to the torque or the twist when they start. But there must be a reason you like it. Just wanted to understand why the worm drives are so popular. Hope you are having a good weekend ... we have rain forecasted for the whole rest of the weekend, and into Monday. As usual thank you for the effort in making these interesting videos, and they are useful too.

[@SoatMon]

I used to have the direct drive style but bought this saw do to the recommendation of an old time carpenter over 30 years ago. I find it much easier to cut a straight line especially if you are cutting 2x4, 2x6s etc free hand on the go resting across your thigh. Cutting rafter ends once in place to even them up you just let the weight of the saw do the work.I don't know if the center of gravity is different, handle placement, or what but to me it makes for much straighter cuts. Hope your weekend is good, we have flood warnings this evening but no rain so far.

[@rightlanehog3151]

I have a Porter-Cable 168A that has been in the family since the non-swinging 60s. You might be interested to know that Porter-Cable also made worm drive saws. The real Porter-Cable tools from Syracuse were fantastic as were these Skil worm drives from Chicago. I will start weeping on my keyboard if I think too long about the tragic fate which has befallen both companies since their glory days. Too late I'm already weeping........

[@ernestomorin3419]

Excelent explnation you are the best help so much tanks

[@SoatMon]

Thanks!

[@tedsykora1858]

I have the exact saw. Love the blade on the left side since I am right handed and can see the blade and pencil line easily. The only thing about the blade on the left I don't like is the fact that I have to reach over the saw with my left hand when cutting off something that needs to be held and have the bulk of the saw base on the larger part of the board. Hard to explain.

[@SoatMon]

I know what you mean but I think that would apply to almost any saw. They are a real work horse.

[@thedude5853]

@@SoatMon Ive had this same saw for about ten years. couple cords and a couple switches but she still works just fine. Never lost any of its power

[@2010stoof]

Did you try using steel wool on the armature where the brushes seat?

[@JesusDiaz-gv7ow]

[@robertphillips5223]

Any advice on the mag77wm22 slow down noise got one and after waiting for oil to come (had to order) and wow sounded horrible when it slowed down so i returned it and the second saw did the same ,either from a cut or free spin it makes a bearing sorta noise as it slowed . is it the norm or are the saws no good .also not looking to bad mouth skilsaw love them but this one has me frustrated any help would be greatly appreciated thanks

[@davidyoung8521]

Some where along the line, the armature design has changed. I have an old all metal HD77 type 13. The field and windings are smaller and the worm drive on the shaft has moved. What exactly is a type 13 vs any other type? Which types are backwardly comparable? Does an armature from a type 15 fit in a type 13? All of the HD77 history sites don't mention " types"

[@SoatMon]

Sorry I don't really know. I've only done the one.

[@Fr3sh-Kush]

Just bought a new mag77 and its doing this😮‍💨😮‍💨😮‍💨. Should i exchange it or fix it? Alot of people were in the same boat as me only to get a saw in similar condition. Domt wanna drive back to the store, deal with that, drive back home and have the same issue😂. Also is it normal to an extent? All the wormdrives ive ever used were old and did this all the time. Your video just made me worried lol

[@SoatMon]

You should take it back if you think something is wrong.

[@hazlbri]

Hi. Great video !. I have a Makita circular saw, and, because when simply picking it up off the bench it's all too easy to accidentally pull the trigger, I'd like to make a safety pin to lock the trigger when not in use. I'm wondering if the trigger is completely hollow and there'd be no problem drilling a small hole to insert a pin at its rear end where it enters the handle casing? Or is there something inside the trigger, e.g a spring or wires(s) that could be damaged by drilling the hole? Perhaps there are better ideas on how to make a simple trigger lock ?

[@SoatMon]

Sorry, I don't have any experience with that.

[@guysolis5843]

I also have an old friend that was constantly in my hand for about 10 years. I've been doing some maintence on it and was going to sand it and make it look real purdy until I realized the saw deserves to show off it's battle wounds. Good video in every way! Also, where do you order your parts from?

[@SoatMon]

Sorry for the late reply. I usually use ereplacements for parts. I agree it's a shame to make an "Experienced" saw look like new.

[@guysolis5843]

@@SoatMon You did a good job and the detail in your video was a lot better than mine. I also used ereplacement for my parts..

What kind of head and size are the long housing bolts?

please give me part number for bearing at armature.

Do you think the older model of that same saw is better? What do you think of the new skil saw models? Thank you

[@davidyoung8521]

What if your HD77 is sooooooooo old that you can't find the part number for the armature? The older models/types have a different armature design.
