    Heat Gun Makita HG651C - Type of thermocouple installed

    I really doubt it is a thermocouple. They require a mess of electronics to function and would serve no purpose in a heat gun. It is unlikely to be a thermistor, either. What you probably have is a thermal fuse, quite common in heating devices, like heat guns and coffee pots. They are in there in case the device overheats. The temp it pops at should be on the fuse. It is probably in °C. They are generic electronic items available from distributors like Digikey or Mouser but it might be less trouble to get it from Makita, especially if you cannot read the value on the old one. The original may be spot welded but replacements usually come with barrel crimps. Solder would melt. Leave enough of the old leads so you can crimp on the replacement. One size does not fit all. Get the right temp. fuse for your gun. Sent from my SM-G900V using Tapatalk

    Watch theYoutube video comparing the comfort grip 24 or 25" breaker bars from Snap On, Matco, Mac and HF. All of the others are well North of $100. The HF is well under $20 with the ever present coupon. On an industrial torque tester it worked just as well as the overpriced truck stuff. In some cases you are laying out tons of money for alleged peace of mind. The Pittsburgh Pro impact sockets are functionally as good as any and very inexpensive. If you can't be bothered, that's fine but there are some very good deals if you take the trouble. Sent from my SM-G900V using Tapatalk

    Parts for All Pro Professional Tools Jig Saw

    There are many brands that some importer slaps a name on with no product support. They intend for them to be throw aways. If it is just the battery, places like Batteries Plus can rebuild a pack for you. I am guessing it is NiCd powered. If the charger is shot you are probably out of luck. It is a sad state of affairs but even some more expensive imports only have a short replacement warranty with no parts and service support. Sent from my SM-G900V using Tapatalk

    wire a powermatic artisan saw to 220V

    That is clearly a misprint. It should say TAPE. They want you to tie and and insulate those two wires together. I prefer a wire nut to tape. To clarify what is going on, draw the 120 and 240 wiring diagrams on paper. Now add a coil between terminals 1 & 2 and another between 3&4. Those are the two windings inside the motor, that the numbered wires go to. On 120 the two windings are in parallel so there is 120 across both of them. On 240 the windings are in series, so there is still 120 on each winding. Sent from my SM-G900V using Tapatalk

    Fix or Replace?

    You don't sound too comfortable ripping into the tool but unless the gear housing is cracked the most likely problem is a stripped gear, which should not be that expensive. It may well involve pressing a bearing or two. If it were mine, sheer curiosity would have the gear case apart but that may not work for you. I replaced a stripped gear set on a Makita rt. angle drill, some time ago. Still going strong. Sent from my SM-G900V using Tapatalk

    How to estimate life of a Makita battery ?

    More like 3.6 x 5. Virtually all rechargable batteries read higher than their nominal voltage, fresh off the charger. A fully charged car battery reads 13.8. They all rapidly drop to their nominal voltage with least bit of use. The lithium cells in power tools are 18650's. Look on ebay, Amazon, Battery Junction or almost anywhere and you will see the cells for sale and advertised as 3.6 volts. This is where we get DeWalt, using 4.2 and Milwaukee using 3.6 coming up with 20 and 18 volts. Back to your question. Lithiums have what is known as a flat discharge curve .It starts at 4.2 and almost immediately drops to a little over 3.6 and very gradually drops a little lower over the whole discharge cycle until it is amost fully discharged and then the voltage drops like a stone. The decrease in voltage is so slight over most of the discharge cycle, that unless you are way over or under at the start or the end it is very difficult to tell what percentage is left, over most of the discharge cycle. Temperature also alters the voltage. Sent from my SM-G900V using Tapatalk
  7. First, if you are talking about the older 18 volt NiCd batteries and 20 volt lithium batteries, they are both 18 volts. They got cute and rated the lithium batteries at the peak value coming fresh off the charger. Run it a few seconds and you are down to 18 volts. Even the NiCd's are over 18 volts, fresh off the charger. This has been discussed to death. Some companies call their lithiums 18 (Milwaukee) and some call them 20 (DeWalt). They can squeeze a lot more capacity (run time) and higher current available by putting cells in parallel with lithium cells. That was never done with NiCds. Brushless motors use power more efficiently and have no brushes to wear out but but torque is torque. Compare torque specs to detirmine which drill is more powerful. For a light user brushless will not show a big advsntage. It is the new sales fad. It is like synthetic motor oil in a lightly used car that gets regular oil changesThere are also new 4 pole brushed motors that are great performers. If the drill is your #1 device, I would look at Makita. They have the best Japanese keyless chuck, as opposed to the Chinese stuff used by others. I don't know anything about their combo kits.

    Best Random Orbital Sander

    Fine Woodworking just did a review of 11 popular random orbit sanders The Festool RO 125 REQ came in as Best Overall, but at $510, that is no surprise. What was a surprise was Best Value went to Craftsman at Sears 320.39592. It performed almost as well as the Festool for only $55. I have concerns about buying from a company that may be gone tomorrow but if you consider it like an HF throw away, it might be a good deal. I am not sure but I think 320.xxxx is Chervon (China), the new owner of Skil that has been making some well reviewed stuff. Sent from my SM-G900V using Tapatalk

    Anybody here still like old-school acetate screwdrivers?

    It goes beyond stink. They develop a white chalky oxidation that many mistake for mold. I have a bunch of old Xcelite drivers in a tool box and periodically I have to wash them off. The white powder and the stink are gone for a while. I have wondered whether a clear coat would prevent recurrence but never got an answer. The name of the plastic is cellulose acetate butyrate or CAB for short. Sent from my SM-G900V using Tapatalk

    Another consideration is quality control or the lack of it. One guy's great buy may have been a failure for others. Read the reviews or comnents here or watch videos and you will quickly find out about the high failure rate. On some items you have to pick through the stock to get a good one. Early failure is not uncommon in electrical tools. The warranty on most things at HF is 90 days. Their hydraulic stuff is not too good, either. They sell extended warranties on some stuff but then it is often not still a bargain. A lot of their stuff is poorly designed and Youtube is full of fixes for HF stuff to make it work. For me, it took 2 kitchen scales to get a good one. The tractor lift had a bad bottle jack . When I walked in the door the sales lady said "bad bottle jack?" Forget about replacement parts for most things. 90 day refund or exchange and then you eat it. I have had good luck with the alkaline batteries and buy them on sale. The cheap free screw drivers have lasted quite well. It is a very mixed bag. My impact wrench has lasted for years and the 44" tool cabinet set is a good deal if you can get an undented one. Mine had a ding in it beneath undamaged packaging. Sent from my SM-G900V using Tapatalk

    DCD996 - Type1 & Type 10 differences

    Something you might want to do is pull up the illustrated parts breakdowns to see if the motors or any closely related parts are the same part number. They can usually be found online. See if they even show different parts lists for type 1 and type 10. If the bundled tool has some economies or one supersedes the other, there may only be one parts list. I doubt if the small change in wattage would be noticable but I can relate to your curiosity Sent from my SM-G900V using Tapatalk

    Opinions on Genuine Makita batteries

    All yellow American and cheddar type cheese is dyed. It is naturally white. Annato food coloring (I think that is #5) is even used in butter in the winter when cows are eating hay instead of grass. Sent from my SM-G900V using Tapatalk

    Japanese steel. While the technology in power tools has increased in recent years, it is nothing approaching what is going on in a computer. Pulse width speed control can be found in a 10 year old treadmill. There are US companies that can make control boards but most of the components will be inported. Even US chip manufacturers have plants all over the World, often in smaller countries like El Salvador Sent from my SM-G900V using Tapatalk

    Combination screwdriver, does anyone use them?

    I have a couple of the cheapos that have 2 sizes of phillips in one end and 2 sizes of flat blade in the other end of the hollow shank, that is removable. One end of the shank is 1/4 hex and the other is 5/16. So I have 4 screw drivers and 2 nut drivers. They are only a few bucks in the big box stores or HF. I would not be without one in the kitchen drawer. I make no claims to high quality but they have lasted for years and saved me many trips to the garage or basement, where my "real" tools live.
