Tool Talk

there's a number of saw sets here, going back to grandad, but they're useless on hardened teeth.

cheers

Bob if your father schooled you like mine did for me, saw setting started with heating the teeth to a dull red (blowlamp!!) then you filed each individual tooth reset the softened teeth, reheated them and oil quenched them at just the right time and technique to reharden but not make them brittle in service. Did all that for years, but these days it is easier to buy a new handsaw for $7 to $15 that cuts far easier that the old ones...:)
Much the same with drills, for years I used to sharpen them as a bit of a party trick when we visited at farms etc, and I still sharpen some of my own collected over the years,drills , but again easier to buy a new one or a dozen..

I meant the Pozidrive has a "cross" stamped for identification between the main cross of the actual screw head.
Pozidrive are different again from Philips and JIS, and are easily recognised by parallel ground flutes driving on the sides of the slotted screw head.
Like the JIS, if you use a pozidrive driver on a pozidrive head, it works.

Thanks for the tip about the JIS, I do remember them from a lot of Japanese stuff, especially carburettors and motorbikes, but wasn't aware of the difference. I wonder if one of my "favourite" tools, the old double-ended screwdriver found in Mazda and Toyota car toolkits, was actually a JIS or a Philips?

Cheers.

Yeap, they are JIS tools. That is my source of JIS screwdrivers as I found nobody knows where to get one here in the shops, let alone most salespeople loo at you like you're a green martian when you ask for one. They are designed to bite into the screw head rather than cam out. Tamiya R/C kits will quickly teach you the difference after you mangle all the heads of the screws in the kit with a Phillips. Annoying as all hell.
 
JIS are stocked here in the toolshops. If all else fails, try a motor bike shop.
 
I learned quickly to raid the Toyotas at pick a part so now have a collection of JIS tools. Nobody seems to use the toolkit that comes with these cars. Maybe says something about their reliability. Quite good quality as one would expect from them.

Ahh yes, Tamiya "sort of" Phillips, remember them well. Wish I had known about JIS at the time.
But your post reminded me of why I have a Pozidrive screwdriver - also for an RC model car. I have an old Schumacher (UK) on-road RC car, and my son had a series of Schumacher off-roads from 1992 to about 2005. Soon learnt about Pozidrive screws, having the correct driver made all the difference. For the uninitiated, you can see the cross stamped into the head of the screws in the close photo, and you may be able to see the parallel flutes of the driver I sat there. The other photo for the brand of driver, these are easily found (Bunnings?) in several sizes, identified by the blue-grey handle. (This driver is almost brand new, the one in my son's RC toolkit looks a bit more weatherbeaten).

I usually ditched all the screws that came in the kits and replaced them with cap head screws (Allen). Much more long lasting, much easier to deal with and I like to be able to do all jobs with only one tool.

Or if you have no welder a Dremel does the trick with a thin cutting disc. Put a slot in the recessed head if you don't care much about the surrounding getting marred and bob's your buddy.

Another good tool is a parallel jaw plier. Especially for grinding small stuff on the bench grinder.
 
They look interesting. You would need the screw partially unscrewed before they work? I've been known to knock the heads of them with an angle grinder if its just screws into timber (that is hidden). If they are into metal, you weld a nut to them.

Yes they show a counter sunk screw, they are for round head and cheese head screws. I have a pair of PZ-58 and they do work well if you can get a grip of the screw head.
 
G'day,

never mind those rich man's pliers, Warren & Brown Screw Removal Pliers, they must stay awake at nights over there in Maidstone - are they still there... ?


cheers,
Bob
