Comoy’s Grand Slam 30D Restoration

By Al Jones

Update: Thanks to Sam’s comments below, we did confirm that the shape number is indeed a 30D. And, I found this shape chart page showing the shape 30. Thanks Sam!


This is the second pipe sent to me by a forum friend. Grand Slam pipes are fairly common and originally came with a complicated stinger with leather washers. Most of the stingers were discarded and was missing on this one as well.

The pipe had a mildly oxidized stem, with some teeth indentions and a heavy tar build-up on the bowl top. I cleaned the bowl top with a cloth and some mild Oxy-Clean solution. As I removed the cake with my Castleford reamer, I unfortunately discovered that at some point, a previous owner had reamed it with a knife or other. The bowl was slightly out of round. I massaged that back as close as possible to round with some 320 grit paper. The bowl was then soaked with sea salt and alcohol. The stem was soaked in a mild Oxy-Clean solution, with a dab of grease on the 3 piece “C” logo.

The pipe as it was received. The stem was also very loose, to be dealt with later.





The briar was buffed with White Diamond and then several coats of Carnuba wax. I used a lighter flame to raise several of the dents on the stem. I used a tapered pin punch inserted into the tenon and then warmed with a flame to slightly enlarge the outer dimension. You can only slightly increase the tenon diameter in this way, but it was enough in this case. Typically smoking the pipe will tighten it even further. The stem was then mounted and the oxidation removed with 800, 1000 and 1500 grit paper. I then used 8000 grade micromesh before buffing with White Diamond and Meguiars Plastic Polish.

Below is the finished pipe. If anyone knows details about the 50D shape number, please add a comment.

        That number is pretty clear abd appears to be a 5. Is there a 30D shape, I don’t recall seeing that either?

    Hi Al,
    What wonderful grain on this one, I lam a sucker for the old Comoy’s. Congrats !!
    Great job . Very decent bowl now.
    I sometimes apply a drop of black nail polish to tighten a tenon. Works like a charm.
    Cannot be of much help about the shapenr. though.
    Thanks for sharing,
