My Wechee reciprocating carver which attached to a Dremel by an extention shaft is leaking black goo between the colette and blade

Terri, this is grease leaking from seal on col-let shaft, or loose bolts/cracked casing. Take apart and repack gears and housing with lithium grease ( do not over pack) and change seal if possible.
My old sawzall from the 1980 has started to leak

Turn the release as far as it will go, then tap on something blade down till it emerges.

Grinder if you have one, reciprocating saw with a metal blade, or a good hack saw.

The drive shaft for the blade is stripped or broken. take it back where you bought it.

You can't attach this to a Dremel Stylus. This blade is specifically for the Multi-Max tool. A link is below.

There are 2 types of clamps that hold the blade in that type of saw.

Since this one most likely has the type where the blade is held in place with a set screw and a "U" shaped piece of metal that holds the blade tight against the shaft. There should be a screw hole in the shaft of the saw. The blade rest next to the shaft and then the metal piece clamps the blade against the shaft. This is all held in place by a set screw that screws into the shaft. This screw uses a hex key to remove and tighten it.

If your tool doesn't have this style then it should have a twisting clamp. This will rotate and release the blade. Sometimes a pliers is needed to loosen the collar, but not to tight tho.

To install blade into saw:
1. Loosen set screw.
2. Insert blade shank from the front between the reciprocating shaft and the blade clamp.
Locate hole in blade over pin on reciprocating shaft.
3. Tighten set screw. If the blade should break off and the shank does not come out of the clamp,
be sure the set screw is loose and eject the shank with a nail or pointed object.

I believe the part you are looking for is called a "locking rod" dremel part number 2610922661, this is the black painted pot metal that is about 3" long attached to the upper arm rocker with a parallel pin, and the flip clamp (blade tensioning assembly) or it could be the small piece attached to the tension assembly that the blade attaches to which is silver and called the "blade holder assembly-top" part number 2610922683. I would recommend ordering both directly from Dremel CS 1-800-437-3635. I broke the locking rod on mine. I emailed dremel, and they emailed me back the next morning with a schematic, and parts list. I bought 2 and paid $10.41 total.

hello. You loosen the arbor at the base of the shaft closest to the tool. There is a tiny wrench in the kit that came with the dremel, or you can use a pair of pliers to loosen it. Joe

Takes an adapter to screw onto the nose of the Dremel. The shaft itself is gripped by the correct size collet tightened as you would any bit.
