As I slowly apply finishing oil to a project gun this summer, I continue to have a bit too much time to think about traditional slakum. And I was looking back at some of the posts here while preparing to make a new batch of oil. I didn't follow an exact 'recipe' from anyone (the effort is recorded at the bottom of the linked document), but in the process of reviewing, I was again impressed by the significant time and effort that Damascus, Salopian, and others have put in to helping interested newcomers understand traditional finishing processes.

I decided to summarize some of the things I had read here and elsewhere, including an outline of Damascus' thread on his process. Doing so was very helpful to my understanding of the constituents and application of slakum, so I decided to type up my notes.

I figured I would share that 'digest' for a couple of reasons: 1. to say thank you to the many folks who have freely shared their knowledge, and 2. to hopefully make some of this a little more accessible for newcomers to the subject.

The link below will take you to a google document that I intend to slowly add to and edit. In fact, there are some missing bits of info that I would welcome some help with.

Also, everywhere that there is an underlined bit of text, it is a hyperlink, either to information or a source for purchasing materials. There are multiple sources for most of these things, and not all of the links are necessarily to the cheapest or 'best', although, over time, I hope to use this as a 'catalog' of sorts for the materials I use most.

I intend for this document to improve and grow, so if you have a traditional oil recipe or process that you would like to share, I would be very grateful to see it. As Damascus says, 'its in the way that you use it,' so please include your process if you have one that's worth sharing.

* I would also note that my excluding some finishes that have been shared (e.g. SKB has been very helpful and generous with information regarding his process e.g. here ), is for the simple reason that I wanted to focus on the most traditional methods and materials-- i.e. no polyurethane (alkyd does make an appearance though). Perhaps a 'modern gun stock finishes of DGJ' is in order, but here I only wanted to untangle the gum arabics and asphaltums and madder roots of my mind.


The document will be accessible by anyone with the link. Feel free to share it if you find it helpful.

Can Dave do as you suggest, move it to the second forum along with Damascus. Hate to see this get buried.

He certainly can. The only question is, "Will he?"

Thanks for the feedback.

One thing that I can do to keep it from disappearing is to post when I've updated something substantially. That would work for a little while at least.

In fact, I have already revised most of the section from Diggory Hadoke's info.

(I also fixed (?) the spelling of slakum to be slacum, which appears to be the right spelling. Not sure why I always want it to be a 'k')

Jim,

Some one posted way back when in the Spring that Diggory’s formula was originally posted or cited in James Howe with modifications with driers. Have you run across them? I inter library loaned his Modern Gunsmith but with the shutdown it never arrived.

I'm looking at it now, and I don't see one that's exactly the same. I'll post them all in a minute. He has 7 linseed oil formulas

Images of the boook posted below.

Edit:
I first posted that Diggory's was closest to Howe Formula #5. But I misread the volumes of ingredients. A closer inspection would suggest that Dig's oil is not derived from one of the Howe forumlae.

Jim,

Thanks and very impressive. Another set of formulas to add to the digest. And yes, they are not a ditto of Diggory’s. I always assumed we coated/soaked with alkanet before finishing but adding it to the final finish sounds interesting.

Thanks John. When I saw how specific Howe is in the formulas and applications, I had the same thought. I'll add them to the digest once I've gotten the info into outline format.

I have made some more substantial additions and edits to the 'digest' and will continue to do so as I gain info. It is now up to 16 pages, and includes forumlas and processes from Damascus, Salopian, Dig, and Ken 61.

If there are other traditional methods hidden in the forum posts, I would be thankful for someone pointing me in the right direction.


Here is the link again, to make it easier to find since we are up to a second page of posts:

Jim,

Again, nicely done. All this information in one place. I am going to order more alkanet and try as per Howe boiling in turpentine and strain.

Thanks,
John

Thanks for a nice resource that you have complied all in one place Jim. I might have to circle back and give slacum a go once again.

If you do give it another try, let us know how it goes. Glad to see your greener re-stock project on the pro page. Looking forward to seeing it come together.

As for the slacum digest, it's up to 40 pages now and includes lots of different formulas.

From DGJ- Damascus, Salopian, Dig, Ken61, and Balistix999.
From non-DGJ sources- J Howe, D Newell, D Mills, D Westbrook, B Farman, N Kypridemos. Eventually, I'll get around to sorting out the info in Dunlap and Walter Howe's books.

I've changed the restrictions to the document so that anyone interested in accessing it will need to have permission. This is mostly for my own curiosity so that I can know who is using it.

If you would like access, please send me a message with your email address, and I will be glad to add you.

Any feedback or suggestions for edits or additions would also be appreciated.

Jim,
Well done in compiling all this information.
When I was heavily involved in stock finishing I found that Naptholene was a wonderful constituent.Much knowledge and information can be gained from the Paint Industry (PPG) after all they provide gloss finishes and air drying products.Although it is a product of our times I dislike poly.

Thanks!
I've got two questions for you:
1. For the naphthalene, did you just dissolve mothballs in your finish?
2. Your Manton recipe included rose pink. I've seen it listed in many old recipes for varnishes / paints, and I've learned that pink is a generic name for a kind of pigment, rose being the color that we associate with 'pink'. nonetheless, I found it extremely difficult to locate online.

A couple of interesting links regarding pinks and rose:
Rose Madder Pigment
Rottenstone Pink

Updated with a "digest" of the Purdey process as demonstrated by Purdey finisher James MacDonald.

James,

I thought you were referring to Naphthalene, which is a major constituent of mothballs. As opposed to Naphtha, which is standard lighter fluid. I was wondering if maybe the naphthalene gave a certain old-closet kind of smell to the gun!

If you look at the Digest, PAGE 37 (Direct Link), I've just reformatted the outline of the purdey process.

The full video can be accessed by clicking the underlined link in the title of that section or by clicking here HERE

To go to the specific time for a given step, you can look at the time in the screenshot that I included from the instagram video.

On that note, every place in the Digest that has underlined text is a hyperlink that will take you to the source of the information, a purchasing source, etc.

Is there any actual formulas for the purdey slakum? I live in the humid south and my minimal experience with the slakum I've mixed is getting them to dry without excessive dry times.

From Salopian:

"Here you go boys,
Purdey's London Finishing Oil
For Darkening, Filling & Polishing
All measures are in English (UK)
1/2 pint of Raw Linseed Oil
2 ozs of Plaster of Paris (Dental Quality)
1/2 fluid oz of Butter of antimony
1/2 Gill Spirits of Wine
2 teaspoons of Vinegar
1 teaspoon of Venice Turps.
You can leave out the Antimony if you don't want to darken the wood.
Leave out the Plaster if you don't need to fill the pores.
That's what is in Slacum Oil."

As for climate, England is fairly humid even if it isn't quite the bayou. I suspect drying times have more to do with ingredients and application than the atmosphere. nonetheless, I built a drying cabinet to have a little more control

FWIW, for oil finishes, I find UV light does more to help drying that most other factors. I don't think it is drying so much as curing that is involved. A couple hours outside in the sun helps a lot (though dust/lint problems then become an issue).

Thanks! I saw that on the document but wasn't sure if it was it. Will boiled linseed work or does it have to be raw?? Another question is will the pure grain ever clear be the same as the ethyl alcohol? The last I made I heated up and cooked. Is this prepared in the same way? Thanks and sorry for all the questions.

Hi

Does anyone here have any first hand experience with J.V. Howe's formula number 1? I would like to hear about it.
