Due to the design of the electronics you commonly work on, I was surprised this repair did not require the recalibration of any parts by the manufacturer to work.

Thanks! There's a story behind the defence I didn't tell in the video. When we started the move of Rossmann Repair a few years back we needed to do some demo ourselves. Hihi and I went over to HD and picked up a Ryobi circular saw. People lost it on stream when they saw that. But that saw got beat to hell and still works.

There's no way I could shame you Paul, why? Despite having so many tools I don't know where most of them are! The tool boxes are empty and I have to be careful where I step in my basement because I might get a nut wrench embedded in the sole of my feet. BTW, I went to my local orange store this past weekend and was shocked to see all the copper wire supplies under lock and key. I asked the 83 year old lady that runs electrical wtf was going on and she said they come in and fill their carts full of rolls of wire and walk out without paying and the staff can't stop them. When you consider some rolls are over $300-$400 a pop that's some major loss. I thought I was safe from the BS living out in the CT countryside, I guess no one is.

I have green tools from the orange store. I don't do much work with them so they're fine. If I needed a hammer drill again, it'd be Milwaukee or Makita. I've needed it once in 20 years, I'll rent it for $20 if I need it again. To be honest, my sockets are S&K and old Craftsman before they became consumables. Edit: if you were one of us, at your bench rate, we'd be better off throwing the damn thing out and buying new :-)

Back in the day when I played airsoft we had the same problems becuase the switch was basically the same design as this. What I and other people dud was that we added a power mosfet + resistor so the switch just turned that on instead and the mosfet handled all the current. I dont know hat mosfet would be suitable, we often used a 30A fuse for our guns because they tend to be very upgraded so they pulled a lot of current! But like you sad there is space so a big one with a heatshink I guess should work.

Great video. My Ryobi blower is having this same issue. Now I know how to fix it. I think I might just pull that whole variable speed switch out and just put a toggle switch in there since I only really use it on the highest setting anyway. I've been generally happy with the Ryobi tools for just light home use considering the price point. I was impressed actually with the 1/4" impact driver. I was replacing the anode rod on the water heater. I could not get the anode rod to loosen. If I put a breaker bar and pipe on it, I just ended up moving the entire full water heater. I didn't think the 1/4" impact would work, but to my surprise it actually did loosen the anode rod!

Nothing wrong with many ryobi power tools. Not much worse than “DeFault,” and not the price. I wouldn’t buy their ratchet or 1/2” impact, but I have many of the others. Batteries and the rest are easy to repair. I have snap on, rip off hand tools, and I like them. Use what works for you, am comfortable, and you’re proficient. The rest doesn’t matter.

You could rewire those contacts so they force the FET to always on when the trigger is fully pulled and let the FET pass all the current to the motor.
@A2000MHz
10 ай бұрын
I might have to upgrade the FET too for that. I need to play around with it and see how much amperage the motor actually draws. I was also informed that there is a replacement switch on the market. I'll get one and tear it down to see if it's a better design. If it's just the same thing then either modify that circuit or add a MOSFET or relay to handle the motor high current. It shouldn't be hard for a manufacturing engineer to change those burnt contacts for some kind of clicking spring design so I hope that's what was done.
@dahlia695
10 ай бұрын
@@A2000MHz The FET is already switching the full current of the motor since circuits like that typically control speed by pulse width modulation. I'd argue that the lower speed is likely stressing the FET more since it's constantly switching it on and off and there's a time on each transition where the FET is not fully on or off and as such is dissipating power, and that wouldn't happen if the FET was just left in a fully on state. But yeah I'd agree an aftermarket switch is probably a better choice then modifying a poorly designed motor drive circuit. They should have made the FET do all the work in the first place (like everyone else does) but they chose a kludge instead.

Why does everybody always feel the need to shame certain brands? Maybe Ryobi isn't the most high performance brand but I can tell you one thing, in the small right angle grinder niche, they make the best one that there is, with a variable speed trigger and it's smooth as hell. Way better than the equivalent from Makita or Milwaukee. Way way better. They typically have more innovative stuff, even if they're not super high performance. I think the days of shaming Ryobi should be over. Update: okay I admit that as a shitty switch though...

these types of engineering choices are often a compounding set of mistakes that have multiple parties to blame... engineers cut corners, qa teams don't test this failure case, inspection agencies don't validate that this dangerous design issues, and it's a disposable consumerist society so the data from the failed versions doesn't get back to the manufacturer... next thing you know you've got a massive recall and billions of dollars in class action lawsuits... building physical products at scale is one of the hardest problems

It's amazing with the way you put it. The design had to go threw at least a few people before it got put into production. This is buried inside the unit where nobody would think to look. I wonder if the original design called for a relay like I want to install into the system but got cost cut out. And nobody thought to change the switch for something more suited. I just don't want to believe that any engineer, corner cutting or not, would spec a slow acting contact for a high amperage device.

@@A2000MHz a big concern I’ve seen is that in the “data driven” engineering world, unfortunately an engineer may not have access to all the information they need to make an effective decision at each stage of the process Picture this - an annual report that shows cost for different parts of the BOM across the entire ryobi product line, some alternatives, and maybe some baseline qa testing results. If the report doesn’t properly show the operating conditions of each product or what kind of power draw can be expected it’s so easy to miss a significant change in the design of the replacement being selected, especially if you’re maybe getting a bulk discount from a supplier for a part that you can use across a dozen different products. And hey maybe 11/12 of those products have a better design where there’s a separate relay for the high-amperage circuit controlled by the cheaper part so it’s nbd but unless either a) it’s entirely clear in the data that there’s a problem in the design or b) you’re regularly combing through the operating parameters of every part in your BOM for every decision you make in the supply chain and design process, these types of things are bound to fall through the cracks Just one of the reasons I’m excited to see how AI could be leveraged to process design files, BOMs, pricing, and be a tool that engineers can use at each step of the process to make sure these things don’t get missed

I've got about 10 of their 18v batteries in my garage currently with an odd assortment of tools to go with them. I have moved to the 40v platform for the heavier load yard tools. I've had good luck with their batteries overall.
