what are they used for

[scottd]

This stuff came with my little RF20 Sears mill. The box of flat stock looks like shims, possibly for the ways??? The other is a collet, but what are the parts under the collet for? And then there is the 2-4-6 blocks, what is the intened use of these blocks? Oh, the collet will not fit the machine, it's R8.

The parts in the first pic are parallels, used mainly for supporting stock in a vise but
can be used for much more.
In the 2nd pic with the 2-4-6 blocks (look more like 1-2-3)are 5C (most likely) collet fixtures
Used for holding round or hex or square stock depending on the collet, also in a vise most times.
Allows you to easily flip the fixture in the vise and miill up to 4 or 6 sides.
The blocks are used for setting up or supporting stock too.
Very useful tooling that can be used in multiple ways.

yea 5c 3/8 and it does fit inside the dodads under it. So it would only hold a 3/8" something, and in a vice. Seems useless at this point. thanks, and nice vids on youtube.

You can get 5C collets to 1 1/8 inches by 1/64ths plus machinable blanks to 6" and internal and external,
and for different shapes.
Very valuable for stock holding but can get expensive for complete sets.

You will quickly find that tooling and workholding will be the most expensive and time consuming part of machining. Do not throw these parts away or sell them, as soon as you know what you are doing, you will need them. Kind of like doing your first cnc rehab, you gut the machine because you dont know what those old electronics do. Soon you start seeing the parts were very similar to the replacements you are installing.

Yea, what he said. As soon as you figure what you doing... you gonna use those parts often!

I'm not going to have much us for a C5 3/16 collet and a holder. 2-4-6 blocks, kinda useless as well. The guy that used to own this little rig was a retired machinist, so he may have had a good use for it?? It came with plenty of other usable goodies. Hold down kit, 6.5" rotarty table, end mills, boaring bar, fly cutter, r8 collets, 2 vices, a few drill bits, and a light. This RF 20 is silky smooth, with an upgrades 2hp motor. And now I'm shopping for a CNC kit, 4 axis, gotta get the rotary table with a chuck.

Good! Then give them to me! I'll use the he11 out of them! :-)

Seriously, since you didn't even know what they are, you have no idea whether you'll use them or not. Few machinists would be without all of those things....

I give some cash for the C5 collet holders. I have a C5 set and could use them.

Send me a PM.

Do those "2-4-6" bolcks actually measure 2 inch by 4 inch by 6 inch? that is a find in itself. Those can be very handy. Never heard of a RF20 Sears mill, Is it something old, just courious.

Might be wrong othe sears thing. It's a Fairbanks Ward RF (rong-fu) 20. The year on the motor says 1983. I haven't found any info on the web, none worth a darn any way.But I did find a manual for the rf20, on this site.

2-4-6?? beats me, thats what they call them. http://www.grizzly.com/products/2-4-6-Blocks/G5642

also have a set of these. http://www.grizzly.com/products/Fly-...-2-Shank/G5716

and another drilling item. It has a 3/16 drill bit and an indexing bar off to one side that holds a cutting bit, like one that you would find on a lathe. I guess that would be used for making holes.

Ha, plenty of interest tells me I have something cool. Collet closers are not cheap, from what I can tell. And it makes a hell of a paper weight, for now.
