In this episode I calibrate the blade and fence of the Dewalt DW7485 table saw, clean the blade and attempt to fix the raising and lowering mechanism. Episode 1 DW7485 review: • DW7485 ep 1 - in depth...
That was very helpful on the blade alignment. Thank you. I bought the 7491 RS, and absolutely love it, but after watching countless set up videos not one described so perfectly the actual blade adjustment. I have a digital gauge, but really struggled with the adjustment. You'd laugh at my attempts if you saw them, but I did zero it in eventually(an hour later). A simple tap, tap, and tap. I love it!

I use silicone spray lubricant on the carriage rods and screw jack. It dries completely, which helps prevent dust from sticking to it. I do this about once a year and it works great all year long.
When tightening the bolts back after aligning the blade, tigten them every other. First a little bit on this, then a little bit on the other. One will offset the blade in one direction the other offsets it the other direction, So what got misaligned turning bolt #1, can be compensated back for when turning bolt #2, so it's possible to keep it aligned while tightening, until they're both tight.
Thanks for this advice…you’ll also like to try a gentle hand lifting the motor as you wind up….you’ll find it moves easily as it should. So, the linear guides aren’t jammed up or lacking in lubricant, but out of alignment . If you hook a light spring or bungee under motor, attached to underside of table then problem is solved for good. Hope this helps too. 👍
Big fan of the channel mate. Haven't left a message yet for some reason. Always catch it on the couch after the gang have gone to bed with a cold one. Nice to hang out in the shed with you after all these years. Nice one mate 😁🤙
Haha! No way. It has been a while hasn’t it! A lot of life has happened! Are you still skating, I saw a few clips on FB i think not too long ago. Great to here from you dude and glad you’re liking the channel. More and better content to come in 2023. Have an awesome Christmas!
@@CaptainofmyShed Yeah mate a few years have swung by for sure. Still skating with the same passion just on the other side of the globe now. Live in New Zealand. Got snared on a trip in 2009 and I'm still here. Merry crimbo to you and yours my man. 😁👊
Sadly the lead screw lifting the blade will eventually strip the female thread in the aluminium casting. You can replace the casting for around 60 pound but it would be better to take the original casting to a machine shop and get an insert nut to replace the thread, probably best in phosphor bronze. The internal thread from memory should be m14 x 2mm pitch, common fault on most table saws.
Fair enough. It’s a bit catch 22. I dont want to put people off but ultimately I do want to turn youtube into a second income so I feel your pain but I hope youll consider supporting the channel anyway by watching through the ads. If not then thanks for the comment all the same!
Well that’s what the guage read so….. Weather or not it maintained that through a cut. Probably not given flex and user induced movement, but I can say this saw maintained within 0.5mm accuracy and would retain 0.1mm in relation to the mitre slot. So I guess, be amazed.
So just before the tapping you see me loosen 2 bolts. Those bolts hold the assembly on which the motor and blade are attached. I’m then tapping the Allen key braced against the edge of that assembly to move it very slightly which in turn moves the blade into alignment. It’s a bit fiddly but it does work. I’d probably use something other than an Allen key in future but that’s what I had in my hand 😂
Hi, I’ve been using a dry PTFE lubricant on the rails of my CNC machine and I’m gonna take a wild speculative guess the stuff I use could be a solution similar to the fox product, but much cheaper. Here’s a copy/paste from the site and the link to the product is below. Anti-Friction Dry PTFE Lubricant is a great lubricating spray for a number of scenarios and environments. Its anti-friction formula makes it perfect for high use or repetitive mechanisms that require protection from daily wear and tear, such as door and window tracks, chains and rollers, power tools, drill bits and lock mechanisms. It’s quick-drying, and sets as a clear film that won’t attract damaging elements like dust, dirt and oil. It also makes an extremely effective mould release agent. Our anti friction dry PTFE spray lubricant works through a range of temperatures, from -45°C to 260°C, and is safe to use on metals, glass and plastics. With the Smart Straw applicator, you’ve got two ways to spray; use the flip up straw for hard to reach areas, such as inside chains, locks or rollers, then flip it down to use the wide angle spray eye for area coverage on surfaces. Whichever way you need to spray, you can rely on the clever 360° valve to work efficiently at every angle, even upside down. wd40.co.uk/product/anti-friction-dry-ptfe-lubricant-spray/ If you search for ‘wd40 ptfe dry lubricant’ it averages between £7-£10 I also just searched fox fluid on Amazon and it says ptfe infused on the fox products. Hopefully, and I’m not counting any chickens, but we could be on to a winner. :) Cheers Mick
The Bandsaw is from Axminster. It was an ex display model, one of their professional range. I think the closest model now is the AP2552B. Selling for about £1200. It’s a nice piece of kit!
The biggest flaw with this table saw is that the miter slots are not perfectly true. Thats a problem because all cuts are based off the miter slots. Any idea how to fix that?
Well I think I got lucky with mine but if you’re not so lucky, then possibly the only solution is to align your blade with just one slot and make your jigs to fit that. Most sled style jigs can be made with a single runner. This said, I’d probably return and request a more accurate replacement.
I appreciate your comment, however a little advice in return. If you want someone to hear your criticism, perhaps take the caustic edge out of your delivery.
@@CaptainofmyShedI disagree with his statement personally. I liked the time you took. Maybe it'd be better if you were a bit more succinct, but overall it was an A- video.
I looked on amazon, and couldn't find a geo tech dial, found one called a neotech? Is that what you meant? Looks very similar and has the aluminium little mitre slot with it you said about. And I wouldn't bother cleaning those dewalt blades that come with the saws. I found them to be utter garbage. I used mine about twice and changed it for a couple of freud blades. A nice 24 tooth for rips and 60 tooth (if I remember right) for cross cuts. Although I do most of my cross cuts on my mitre saw, which has a 254mm Freud mitre saw blade on it too. So basically got a cross cut blade for a table saw for nothing. But as it's new and cuts so good I use it for finer work at times. Definitely worth cleaning your blades though, makes a mega difference, like a new blade the first couple of cleanings, I've known people to throw blades that just need a clean. Makita and dewalt make some decent tools, but they don't make great blades. I do put my makita blade back on my circular saw and mitre saw if I'm cutting anything that might have nails in it (which is very very rare) as I think they have the ability to go through nails? I'm not sure if they're supposed to, but I've gone through a few and didn't even feel them. So I keep the old blades that come with them for that stuff. But wouldn't want to go through nails on a table saw and so have no reason to keep the shitty blade that came with the table. I think threw it away, or maybe gave it away? So yeah, my advice would be to get a nice freud blade for the table. I don't think they do a dedicated table saw blade at 210mm, but I use a circular saw blade, they use the same mechanisms as table saw. A table saw is basically a circular saw upside down and vice versa. Never use a mitre saw blade for a table saw or a table saw blade for a mitre saw though, they are NOT interchangeable. The angle of the blades aren't the same. Just I'm case anyone doesn't know that, could be dangerous, especially using a mitre saw blade on a table. Wouldn't be too bad the other way round other than maybe some bad cuts on the wood. Great videos though. Enjoy watching. Cheers. Also, what do think about wd 40 dry for the table? I have some of that kicking about, never really used it, but might come in handy now. I also haven't had the same problem as you yet, but better to prevent it than cure it.
Hi Ricky. Yes Neotech Geotech, same difference, mines geotech but it’ll be the same thing, it’s not a very high end item but it’s plenty accurate enough for this application. I have a 10” Freud blade for an older saw I had but sold on and (spoiler alert) I’ve just bought myself a new10” saw for Christmas, unboxing to come! Wd40 doesn’t work to lubricate. I’ve tried it and from memory it worked a bit initially then seized up again fairly quick. I’d get a dedicated lubricating fluid. The fox stuff is stupid expensive and I bet the same product is sold under a different name for a different application and much cheaper but I haven’t searched that out yet. Glad you’re enjoying the videos, plenty more to come!
@@CaptainofmyShed definitely looks the same. I assume it's some Chinese thing. I have one of the cheaper blade angle finder things, works completely fine too. Sometimes it's fine to go with the cheaper stuff, especially on the job site saws. They parent terribly accurate, although I was lucky with mine, it is incredibly accurate, it was out of the box, although my bevel adjustment is very tight to move, win some lose some guess. Yeah, I have some wd 40 dry. Its supposed to be a dry lubricant? Did you try the dry one? I can't remember where I got it, I never bought it I know that, and I rarely if ever use it. I use my wd 40 regular for squeaky doors all the time. But this dry one I've ever used I don't think, so when you said you need a dry one I thought of that and hoped I may get some use out of it. Will look forward to seeing the new saw. Nothing like a new tool for Christmas. I tend to buy myself new tools all year round unfortunately. Bit of an addiction of mine it is. I fear we may all be tool junkies. Hope you and the family have a lovely Christmas. ❄☃️🎅🎄
