$5 off $20: CT: 6-8 Sept.
 

From the flyer this week, I would suggest the tap and die set for 34.99.. so it will be 29.99 or less based on the what your gift card gives you. Or you can spend it on Mobil1 oil which is 5L for 24 bucks (very limited grades though).

For those who don't know what tap and die are. They are used to create new threads on bolts or roundstock (die) or making new threads in screw holes.

Besides that, it is useful to clean / renew some old gunked up bits.. for me I needed to use them when I was taking apart a V12. It is definitely not a tool to learn how to use when you broke the bolt etc.. Practice on something no consequential like someone elses car first. Use plenty of lub.

Looks like the set comes with a thread gauges that will tell you which correct tap / die to use.

The impact socket set for 24 bucks also looks interesting, but I don't think you really need that for a home DIY scenario. Most of the time, you will get into trouble more than anything.

Do you have a link to the tap and die set? I need one but a lot of the kits I've seen don't have the right thread pitches that I'm looking for.

Yup it is Mastercraft Tap and Die Set, 76-pc | Canadian Tire

KMS carries weird thread pitches.. prices are reasonable if you are on the mailing list (just use your neighbours or street # that doesn't exist).

Ah, okay. Too bad it doesn't come with more fine thread as it looks to be mostly coarse thread.

Yeah, I've bought some oddball thread pitch taps through KMS and Raider before. Those single pieces get damn expensive.

Pretty good sale, picked up that tap and die set, a new multimeter, digital calipers, and torque wrench.

Now, anyone know a good place to check the torque wrench calibration?

The easiest DIY way is to get a digital torque measure add on when they go on sale.. and measure your torque wrench against that. There should be a very small flat head screw head somewhere on the wrench body where you can calibrate.

Since most manual torque wrench are spring/torsion based, calibrate the points you use the most. eg I use my 3/4 to build motors the rod torque specs are 45-75.. I calibrate the torque wrench on 40-80 in 10ft increments. Have multiple ones if you are planning to use it in a lot of different applications.

Remember to reset the wrench back to 0 when you are done with it.

THIS! Relaxing a torque wrench after usage is what keeps the spring at the correct level so the wrench remains calibrated, along with not using it as a hammer and so on. Its not a delicate tool, but use it properly...

Honestly buying a 1/2" drive or 3/8" drive torque wrench is cheap, but getting it certified can be pricey, there are lots of places that do it. But most backyard mechanics would probably find it easier and cheaper to buy a new wrench...

Acklands-Grainger charges something like 200 bucks for certification of a 1/2" drive torque wrench, and the price goes up from there for 3/4" drives and 1" drives.

My work sent a hydraulic TU-12 torque wrench in it was $1500 for a rebuild and certification, on the invoice $1000 of that was to pay for the certification.

Damn...that's pricey alright. I called McCann and they quoted $60 for 1/2" and 3/8" calibration and certification. Even that's almost as much as each of my wrenches haha.

Yeah, if you're using lower end torque wrenches (Mastercraft, Craftsman, Powerfist/Pro Point, etc), it usually makes more sense to just go buy a new one or replace it under their lifetime warranty. However, if you're using a Snap-On, Mac, Matco, etc., it's usually worth the cost to have them recalibrated.

would have been nice to see this a couple days ago, i need a tap set!
