Well, as if I didn't already have enough machine projects to keep me off my fun projects for the next year, I just couldn't help myself and brought home another orphan! :eek:

I'm now the proud owner of a Bridgeport E Head Slotter. Looks like very light use and still has the original flaking on the ram. Very smooth and tight in every way I could check (no power). Unfortunately (sorta), it's set idle for the last 20+ years of AZ summers. So it's covered with gummed oil and tarnish. And of course, someone just couldn't help themselves and had to paint the Mill is was mounted on with slathered "porch paint" (hey, at least it was gray!). Now that gray paint looks like a dry lake bed. <sigh>

So, one more machine to take apart, clean, paint (I rarely paint, but no choice here since I'll have to use stripper), before lovingly adjusting reassembling. And only then begins the fun of learning to use it! With only about 6, maybe 8 at the most, actual shapers in the entire SW US, this is as close as I'm likely to get. Still, it should do most of what I want (and dare I say need?). Given what they usually go for, I think it was a decent score at $200. But then it's the first one I've seen for sale locally (only a few around here that I've seen at any time), and even back east they bring $500-700 + shipping.

<sigh>
:confused:

As I recall, meths is the test for acrylic or oil based paints. It reacts with acrylic but not with oil base. If the porch paint is acrylic and the original stuff is enamel or better. Methylated spirits will help lift that acrylic, lay a soaked rag on it for a time then lift and remove acrylic.

You can find the additional information here (http://www.lathes.co.uk/bridgeport/page4.html).

No idea how you could utilize (or make) one on your mill. To mount one either vertically or horizontally, I would think you would need to remove the head. And that is no fun at all, so it probably wouldn't get used if you did make one. Now if you could find a donor minus the head, then perhaps you could do something, but I would prefer to make it veritcal. Driving it horizontally is going to put some SERIOUS hurt on your table screws and nuts.

If you got THAT slotter for $200 you stole it:D Around here they usually bring more than the b-ports next to them at auction.

It's the Model "E", second on the page after the Model "T" Cherrying Head. And yep, that's what I got. I've seen them for $500, plus shipping from the East Coast for a guaranteed "E" head that had been cleaned up, but that's about the best I've seen it for until now. But that was too much for my expected benefit. I hope to know how it works by the end of this weekend.

This was really fortuitous as I need a specific gear for a project that needs a keyway. I can get a gear cheap, but none with keyway and correct bore at any price. So my options were limited.

1) Sit and file it, and be no better off next time.
2) Make a hand stroked shaper out of my mill spindle. No easy way to lock the spindle, so not ideal as it requires a separate project to enable...
3) Same thing as #2 but using the lathe bed. Less than ideal since it also requires a spindle lock project, but this was my plan (for several reasons).
4) Build a hand stroked slotter for my lathe ala our Japanese friend and others, also requires a spindle lock (and one reason I was choosing #3 for future consideration). I like this a lot, but I'm buried under projects for the next decade and didn't want to promote this to the front of the line.
5) Get stupid lucky and stumble onto a local slotter for my Bridgeport at a price I'm happy with.

I guess the suspense is killing everyone by now. Any guess as to which way I'll pick? ;)

Anyway, I just mention this since I was looking at almost the same problem when I fell backwards into this slotter deal. Heh, I was actually there looking for scrap 6061 and tool steel drops when I saw the slotter sitting there on a pallet in all it's paint sloughing glory, right there in the middle of the open floor like it was put there waiting on me. I was almost afraid to ask about it, figuring it was sitting there because someone had already bought it.

Here (http://homepage3.nifty.com/amigos/slotter/slotting_tool-e.htm) is the Japanes guy's slotter. Evan made a nice one too, and I know there are several more that have been posted. I've got a bunch of pics collected, but I don't recall which belonged to which...

I only need a "light-occasional" slotting attachment that will fix to my vertical v-slide and be vertically adjustable for height and travel - "horizontal" is a "non-event" as you say.

Horizontal works fine on a lathe, by hand power. I became tired of racking the carriage to make slots so built this one.

It replaces the compound on the lathe. In this pic I am making a cog belt pulley.

Here is an example of a keyway done with it. It only takes a minute or two to set up.
