How to cap opening on Jigsaw

I got this jigsaw from my father in law. It’s old, has good weight and saws well. It has an opening on the top that looks like it wants a screw on cap. My initial thought was to use a bottle cap, by I haven’t found anything so far.

I’m also wondering what the purpose of the cap was? Should oil or grease be put in here?

My old Sears jig saw has a knob on top. Push the release button and the knob allows me to rotate the blade mechanism. Handy for scroll cutting in tight spaces. Maybe that saw had something similar.

This is an old craftsman jigsaw and there's no indication that this threaded part is anything but a cover to keep something out or something in. I think it is easily 40+ years old.

I had one of those! and loved it!! auto-scroll saw maybe?? the blade holder cracked and I held onto it for 15 years hoping to find one, pitched it. :^(

All the images for those saws show a knob there. If it's not a scrolling saw then I have no idea why the hole is that big.

I'm not sure if this will solve your problem, but I have an old jig saw that was my dad's. It's 1940's to 1950's vintage so like me it's probably over 70 years old. Anyway, as you can see from the photos, there is a hole at the top. In this case the hole provides access to a vertical screw that locks the blade in place. Have you figured out how to replace the blades in your saw? If not, shine a light down that hole, there just might be a screw that you need access to.

After googling the Craftsman model number, I found some picture of saws that had all their parts. It looks like the threaded part is just for a knob for two handed operation. That wasnít obvious to me since the handle is so close to where the knob would go that thereís not really room for two hands. Thereís a shaft that moves up and down inside the opening that I guess could benefit from some occasional grease.

One thing I didnít find online was any source for replacement parts. Any ideas for how to fabricate a cover of some sort?

Get creative ....

You can either use a rubber plug to seal the hole or find a large plastic cap from a tea or milk jug. There are pipe caps that protect the ends of water pipes when you buy them which may also fir over the threads. Looks to be like a baby bottle type thread, which may also work. Go to Ebay and check Craftsman jig saw parts.

The answer to your question will only be as detailed and specific as the question is detailed and specific. Good questions also include a sketch or a photo that illustrates your issue. (:< D)
