I've found that small amount of play in the pivot doesn't have as big an impact on the cut as most guys think it does. It has a lot to do with how you operate the saw, smoothly and not wrenching it to one side or the other during the cut. The spinning blade seems to help to stabilise it somewhat (like a gyroscope, I guess) as well.

Jeremy Schmidt Even with some play, the spring will act on the pivot, pushing the knuckle and pin together at a point. Of course the best situation is zero play and zero flex, but realistically that's not actually needed for highly accurate cuts in wood.

The trend with big corporations has been "shrinkflation". In particular with food, but it has crept into nearly everything. Many of us have noticed this trend for years, but it is likely many have not. Package sizes or contents within those packages found at grocery stores are have gradually shrunk while the prices may have stayed the same or even go up. Take a look at your favorite items next time to see just what I'm talking about. Items that used to be 12oz are now likely to be 10oz and so on, some are even more gradual than that with fractional oz, ml, etc. We are all getting more and more ripped off every day. Either stop buying those items or take the time to call or email the companies that produce them. You'll likely get a sickly sweet and canned answer but stay after them or tell them you are switching to another brand.

There are several problems with that... They likely wouldn't have the proper size to fit an existing shaft AND housing. They would need to be 0.02-0.05 mm increments to provide a proper fit. Those are good if you're using ground stock and if you're boring the housing out to fit the bearing. Even if that was an 18/20 mm i.d./o.d. situation, the hole and shaft are going to vary too much to have a proper fit. He would either have to machine the housing i.d. or the shaft o.d.

I did the same thing about 20 years ago with a Delta compound miter saw. The only difference is I made the bushing out of oil-impregnated bronze -- it's a really good self-lubricating bushing material, and it machines like a dream. I took a really, really (really!) long time to sneak up on the right dimensions, and managed to get lucky and it fit the first time. The tool is still tight two decades later.

+fuqmee Good to know! Sneaking up on dimensions doesn't work with this plastic, so that adds an extra challenge. If I try to sneak up on it at 0.0005" at a time it won't cut...won't cut...won't cut...won't cut... and then suddenly takes of 0.003". So I had to make the last cut about 0.005" deep to get a accurate cut. Shoulda used bronze I guess!

FINALLY It took me 80 years to find someone that is a particular as I am. Wow! I have NEVER seen or heard a person (except for one) talk about the side-to-side "play"; inherent in all miter saws, before now. The one person was a technical rep (he no longer works there) for Highland Hardware in Atlanta, Ga. He critiqued one of Makita's new miter saws years ago. And his only "beef" was this very problem. Sadly, Makita was madder than hell that he had said what he did. But as you say, and what he said, is 100% true. Also, I agree with the construction tradesman. They simply do not care and one of the main reasons people have untold problems in new homes; nowadays and VERY sad. Most DIY'rs do not care either. But for those of us, (precisely as you say) it is truly wrong to produce a product with a KNOWN inherent problem; that is easily fixed. They SHOULD use sealed, precision ball bearings with ZERO "Play". No reputable mechanical engineer would ever approve such garbage as all miter saws have. But of course you made it probably as good as it can be; without rebuilding the machine. You did an exemplary job of explaining the problem. But better, your tenacity found the answer working within practicality. You are a cut above young man. May Jesus bless you for using your gifts to help others.

Felder (parent company of Hammer) saw the video and invited him for a factory tour and then gave him their redesigned 90 degree stop. So there is hope that some engineer at Dewalt may see this video and have the issue fixed. Hot that it would cost much for them to make a better bushing for the pivot point of the saw. Good video.

Dewalt isn't that kind of company from what I can tell. And Jeremy addressed this in the video, they aren't marketing to people who do highly precise work. Your average DIYer or contractor does not need that kind of accuracy. There is just not enough people demanding that kind of thing for a big tool brand to do this. There are niche tool brands that cater to those needs, but they are obviously going to cost an arm and a leg. It's simple economics. Dewalt make good saws, that do exactly what their target market wants them to do.

Hmm, thanks for this. I went out into the garage and checked my chop-saw (not a DeWalt). I've been having problems lately with it not cutting straight, the cut is skewed and screwed - i.e., not straight at all. It used to be very accurate. I use mine for both metal and wood. Following your demo I could see mine also has some side-play. I've used Acetal for bushings in the past - good material, and I get mine free :-), but in this setting I would have thought a bronze or brass bushing with a slightly smaller pin to allow for thickness of the bush might be better. But you used what you had, and it worked.. Good going, thanks. Les in UK

Good 'fix' ! (( I concur with the post about using Delrin, if plastic is to be used - though a lubed sleeve of stainless would work too ! )) Honestly; if , ( If is the biggest two letter word . . . ) cast iron 'bushings' were pressed into the bore in the aluminum housing , it would make for a superfix . . . * give the same job to a thousand machinists / mechanics , and you would likely see a thousand different repairs !

If you wait until it growls or slows down, it might be too late to save the bearing. They are not so easily removed.

Upon seeing your problem I had an idea. I wonder if you could use a reamer in some way. You know that they have expandable cutters.

The cutter blades can easily be ground so as not to be sharp and to a precise size.

Now however you have gone and repeated the 'offence' so to speak; the old dimples have been filed off and now you have two brand new ones. You are not likely to take your saw apart again anytime soon ( one hopes! ) but...who knows? Therefore, how about inserting two brass pellets, between the set screws and the shaft ? It routinely done. anyway, think about it. Cheers.

+Carlo Antonio Martinelli I realize that this is what I did, but as you said I don't plan to take this apart again. The problem with brass pellets is that they reduce how well the screws hold.

I went thru three or four saws over this issue, gave up on the sliding compound variants and ended up with the saw you show. I like how you took the side to side slop out. I still dislike how the turn/miter table isn't flat with the side pieces and the plastic insert part isn't flat with the turn table. once those three areas are addressed I'll be fairly happy with it.

Years ago I was an apprentice machinist and one production job I worked on was the making of valve guides for Porsche engines. They used a material called "Oilite" (not certain of the spelling). I believe it is still used in electric motors for armature bushings. This material would be ideal for these bushings. I think Olite is porous bronze designed to be impregnated and retain oil. It machines well and doesn't deflect like the UHMW. I'm sure it is more expensive but I think it would out last the miter saw. Maybe Dewalt and other manufactures would spend a tiny bit more and make more accurate and durable tools. I guess I'm old school and still not a fan of plastic bushings.

+Gil Grace I wonder if it's ok to use with aluminum? Were the Porsche heads aluminum? I originally thought of using brass but then thought of it the brass corrodes aluminum (or vise versa).

Yes, the Porsche heads are cast aluminum and these valve guides press into the heads. Bronze is not the same as brass...although I think bronze has some brass in it, but I'm not a metallurgist. I was told the oilite is made of particles of bronze fused together. This leaves pores in the material, and allows it absorb oil and retain it...ideal for bushings. A single drop of oil would last for quite some time in this application, less time in a spinning fan for example. Then you simply add another drop of oil. Should not react with aluminum to my knowledge. Look for a production machine shop and you might pick up the waste end of an oilite bar.

+Gil Grace Good information, thanks! I'm sure Porsche did their figures so I'm sure it would be ok then! If these ever wear out I'll definitely check into Oilite.

I really enjoyed watching this. I wish I could do the same for my saw or order better bushing for it. John's comment below is true but a more accurate tool is always nicer. Lining up a miter saw to a line is not as easy as lining up a hand saw so removing play would be welcome, especially for mitered cuts where I find this to be more onerous.

Anyway to put a Zerk grease fitting on the plastic spacer to ease operation ? Building my house in 2000, I did all the stairs myself with my ex son in law using my 10 in Mikita compound saw. Installing white oak and using a thin kerf blade, the blade wobbled horribly against the oak. Bought a pair of stabilizer washers about 3 on. inches diameter. That solved the wobble problem. The saw is a LS 1010, about 25 years old. The only real exercise it has ever had. Nice video. JoeB . JoeB. (New subscriber)

It is acceptable! 1000's of trim carpenter s like myself use these saw everyday to make a living, yes,, there are some faults, but I started with a 9" Rockwell miter saw and these 12" Dewalts are by far superior and don't cost a fortune like the euro stuff.

For those without a lathe I would recommend trying some retaining compound on the bushing. Something like Loctite 638, 660, 680 might be good, depending on your saw and measurements. It will take up some gaps and correct for sizing and out of round.

Jeremy, Great Video. I enjoyed watching. You probably should have made 10 new bushing while you were at it, and sold them. Not a coincidence, I have a new Bosch contractor table saw with the same blade slop; it's keeping me from perfect picture frames. Let me know if you ever make a video about that! Keep making!

You use whatever you have (you did a good job), but Delrin(acetal) or nylon would have been a better material for the bushings and they turn/machine much better than uhmw. Both are much harder and stronger.

You could also consider doing the bushings with metal and nickel boron coating (compensating for the thickness of the nickel boron coating, of course). As some AR15 bolt carrier groups are NB plated because it (reportedly) removes the need to lubricate, I would think that this would be a pretty good fit.

why not teflon?
@barrygerbracht5077
7 жыл бұрын
teflon is very soft and much more expensive than nylon or delrin. You want a relatively hard plastic to be able to machine it easily. Soft materials like teflon and especially uhmw are stringy and don't cut very nicely and thus are very difficult to get tight tolerance parts like Jeremy was looking to make.
@chrishoesing5455

Although delrin is undoubtably easier to machine, I think uhmw is more wear resistant. I have used both for making bumpers/stops at work for different equipment and the delrin wears out quicker.

I liked what you've been up to with your miter saw, now you need to get a piece of quarter sawn oak or something just as durable and make you a zero clearance throat, that way you when you mark your board on the front side and slide it over to the start of the zero clearance line it will help you cut a perfect line. mark

Love it. UHMW PE is good stuff, but maybe PTFE or bronze would have been good candidates. Using bronze, you may have got away without a mandrel. I noticed you ran up the grub screws against the bushings. I would have made a small window. I bought a cheap Skil miter saw for rough framing. Months later, recalling what a smooth cut it made, I tinkered with it until I got precision cuts for joints and moldings with it. I have "optimized" many tools before ever using them, so I know exactly how you feel.
