Finishing CPA stock

I’m ordering a CPA rifle for silhouette. I’m thinking of ordering it ready to sand and finish. Has anyone else tried that? Any thoughts on doing that?

Thanks,
Rich

I have done a plain wood silhouette stock for my CPA as well as CPA stocks for my Rolling Block standard wood and semi fancy BSA Martini International MKII.

Easy to fit and finish as long as you take the time to work down with different grits of sandpaper and thoroughly sand etc.

CPA has provided good wood selection when I requested a wood upgrade.

If you are careful its pretty easy to finish the CPA stock. Where you need to be really careful is around the upper and lower tangs and the metal is finished and you don't want to hit that with abrasive paper. Other than that its a pretty straight forward job.

Tape the metal surfaces prior to ever trying to sand the stock with it on the action.

I do the last little bit of finishing sanding with the stock off the action once I start sanding down the tape.

I rub on Tung oil with my finger since it fills the pores better and puts on an even light coat that will not run (which happens when you use a brush).

These were unfinished wood from CPA. I sent them a blank of Colorado walnut to go on the CPA they were building for me; I sent a blank for them to cut for the Stevens 414; I ordered the wood for the Ballard from them to cut (just select from standard). It just takes time for you to prepare for the finish but since I use British red root oil the preparation time was minor compared to the finish time.

I did the exact thing. Wood was sanded and ready for finish. I followed the instructions Gail gave me and it was an easy process. I had no experience in this before this one and mine came out very nice. Feel free to PM me if you have more questions.

My first CPA was bought unfinished, no special selection still some nice walnut.

Sanded and finished using methods I have used on furniture and lathe work for years.  “ going through the grits” sanding not skipping any 120 to 2000 grit paper from Klingspor”  after initial shape at about 180 grit applied a thin wood filler “Mylands” and worked up to 220 then first coat of Watco wet sanded. At some point shifted to dry sanding, wood tells me when, probably 1200 or 1500 grit. After the finish really starts to shine. Last and after the oil is good and dry light coat of wax. I’m using mostly “Williamsville” it’s thin and rubs on with the palm of your hand easily.

Several years later sent it to a stock man who checkered it and at my request re oiled after with Watco and Wax. 30 years later it still shows well and the occasional Nick and bump blends in, adds character to the gun.

My 2nd CPA Pope style high comb stock went for upgraded wood, nice figure and finish. After about 20 years sold the Pope stock and had CPA fit finish and checker a Sporter stye stock to suit local match rules. They did a very good job either one and well worth the cost vs time and effort to finish my self.

3rd CPA ordered unfinished and very plain receiver blued not color cased. Stocked and sighted for longer range. Loaned it to Ken Burklow “line cutter” on this forum for the Quigley. He liked the gun and bought it from me. Transforming the gun into a real showpiece. Engraving and stock finish.

All my original Rifles and Shotguns  have original finish, most cleaned with soap and water then rubbed with oil and wax. Lately have shifted to simple boiled linseed oil and wax mixed and hand rubbed. It’s a good solution and preserves original appearance. I wax those guns metal to preserves and protect without a strip and refinish. Like the results better than most reblues or color case jobs.

Have a few shotguns bought already professionally refinished by real craftsmen, those jobs are worth the cost, particularly bringing out Damascus figure on barrels and not harming originals action engraving 

That’s all I know about it

I went that route on my CPA stock as well.  

Got the wood, extra fancy, ready to sand and finish.  After sanding to about 400 grit, I started finishing with Tru-Oil.  I wet sanded the first five or six coats to help fill in the pores on the wood, then continued on till I got about 25 coats, lightly dry sanding between coats.  The final coat produced a more shine than I wanted, so I did a final rub with Stock Sheen.

The process took about a month.  You don't want to rush this.

I liked the fact that I could save costs by ordering it unfinished from CPA, so I used my savings to purchase upgraded wood quality. Then I had the pleasure of finishing the beautiful wood to my liking. After many many coats of tung and walnut oil, I like how it finished. 

There’s something to be said about spending a couple months of time watching a roughed out set of lumber turn into an exquisite piece of art. Not all will, but I enjoyed the investment of time and appreciate that I had a hand in creating an exceptional rifle.

That’s a lot like I did. Not so much to save some money. I finished the furniture on my Rem Rolling Block and thought I’d have “fun” 

I ordered the rifle in late Sept. and it arrived here in late Feb. I spent all of March sanding, paying close attention to the fit of the wood to the upper and lower tang areas. The wood was always removed from the rifle for any sanding.

After that patience testing activity, it was time to select the finish. I ordered the wood as “extra fancy”. I learned that CPA uses Birchwood’s Tru Oil. I found some and started with that. A friend told me that for his CPA’s he diluted the Tru Oil 50/50 with paint thinner. I did not do that.

To me, the Tru Oil came out too dark and too brown. Before using it,I rubbed a rag with water on the wood and the result was really nice, convincing me I wanted that appearance for the final finish. Attempting to get away from the Tru Oil darkness, I found some small cans of stain made by Varathane. I started with Golden Pecan, then Gunstock and settling on Sedona Red. I really wanted a hint of red but not as red as the photos I’ve seen of old original Stevens rifles. I did not try to sand off the Tru Oil layer, the wood just kept taking the Varathane stains.

After several applications of the Sedona Red, I convinced myself to stop. At the end I applied two applications of Renaissance wax, something I read being used over on the Shiloh Rifle forum. My #1 goal was to avoid the final look of an overly glossy stock having been dipped in plastic. My final appearance is more of a satin finish, avoiding the high gloss.

Do it again? Yes, but not until I get this CPA to shoot, which requires me to find a Weber .38-55 breach seating tool. It’s a lengthy adventure!

Tom

Oneatatime,

Ok, I’ll try. Actually the CPA’s shooting side of life is coming around. I just have to be even more patient than I was with the finishing.

CPA sent me a dimensioned sketch of the area of their chamber that is provided for breach seating. I gave those dimensions to Accurate and they made a tapered, 4-cavity brass bullet mold. That’s what I’ve been using so far. (I have a 4-cavity 335-grain NOE brass bullet mold and a Saeco #571 2-cavity mold and both are tapered but both are way too “fat”.)

Since I don’t have a Weber type breach seater tool, I insert a bullet, then insert the CPA plugged case, tap on the base of the case with a nylon rod and plastic headed hammer (my fingers aren’t strong enough to push the bullet in all the way in), then use the rifle’s “camming action” to finish pushing on the plugged case to finishing seating the bullet. Remove the plugged case….I did try to shoot the plugged case a few times so far!

That inserting the bullet, picking up the plugged case, inserting it and then picking up the rod and hammer and then tapping on the rod and then put them back on the bench (out of the way), is distracting at a CBA BR match. That activity is what I was thinking of when I said “but not until I get this CPA to shoot”. 

The 9-12 bhn Accurate bullet weighs about 345-grains. (I was hoping for 320-330-grains). The barrel is a 30” Bartlien 1:12, 5-groove. (Never heard of Bartlien before I got into looking at a CPA.) The unsized bullet is lubed with SPG in a 0.380” RCBS CB sizing die. I started with 16.0-grains of IMR 4227, then 17.0 grains, then 18.0 grains and will now next try 18.5-grains.

I’m on the hunt for the Weber type breach seater….still.

Tom

While you are waiting you might try making a shorter plugged case so you can use the action to seat it. I made an adjustable plugged case.

Hi Tom,

Check the dimensions on the bullet your using.The Mos mould CPA offers is .378" tapered to .368". The moulds they offer are cut to fit their chamber. I do use Weber and a Mos seater in my CPA's but before I obtained them I used the plugged case they offered. I was able to seat the bullet with the camming of the breach. This was for the Mos bullet mould I obtained from them. I couldn't use the plugged case with other moulds I have. I would have to use a tool to get it started before I was able to use the breach block.

This was the same for all the barrels I have on my CPA's. 25-20 WCF, 32-20 CPA, 32-40, 32 RKS & 40-50SS.

RK,

That’s what I did. CPA sent a bullet (with the rifle) that they seated in my rifle, the Mos product that they offer. I took dimensions from it and the throat dimensions that CPA gave me. That info was given to Accurate to make the mold. 

I could have bought the Mos mold but it’s a single cavity and I have a Paul Jones single cavity mold for my .40-70 Sharps CSA rifle. That mold works well. I just wanted to have more than one cavity for the CPA .38-55. Accurate did make the mold right where it should be to replicate my starting dimensions.

One key to this effort is the hardness of the alloy. The softer the better for breach seating the bullet. And if the bullet dimensions are on the “large” side, going a bit softer lets some of those dimensions sneak a bit closer to smaller.

Unlike most readers here, this is my only CPA and my first breach seating effort….so lots to learn!

Tom

It will emotionally bond you to that piece of walnut and you can watch it turn from a featureless chunk of wood into a living thing.

The last two rough stocks I got were  terrible.I should of sent them back....but my wood !  Hopefully the new guys have the stock duplicating down a little better ???  My other stocks from years ago were always done very well.....The thru bolt hole that I had already done is off center from the duplication...no excuse for that ,dont know if I will have enough wood on one side,my wood,my drilling dead on ..then screwed up
  

May the Bullet Gods be with you.......

I saw that quality issue in another forum and commented on the CPA duplicator being a homemade contraption Paul built in the days of the rotary phone. It obviously did great work if great care was taken.
I was planning to get a handful of CPA stocks for winter projects soon but now am concerned on what the quality will be. If anyone has current good/bad experiences please let me/us know.
Thank you,
Charles

My experience was similar. I entrusted them with a beautiful piece of quartersawn fiddleback walnut for a Ballard and the stock I got back looked like it was mortised by a blind beaver, but in fairness the outside was shaped ok. The barrel channel in the forend was several degrees out of kilter, but luckily there was enough meat left on it to allow reshaping the outside to conform to the channel. This was two years ago.

To add to the last few comments here, my experience of stock blanks from CPA was horrendous. I've done plenty of stocks before and I certainly don't expect drop in fit, but these had some major dimensional issues with the inlet.

I got a set for a pistol grip low wall. The inletting and shaping was that horrendous I just put them aside until I could pluck up the courage to take it on and try and address the issues - which the severity of wouldn't have been apparent fully until the work was started. The inletting was terrible and the lower tang is off centre in the pistol grip (which I "may" be able to correct with careful work but I'll be lucky if there is enough wood on one side) and the lower tang is cut far too deeply that I will have to add wood or bedding compound in order for there to be something for the lower tang to rest on and screw into. When I say cut too deeply, I mean 3/8-1/2"+ lower than what it should have been. I will HAVE to put wood back to rectify as the tang floats in air.

I didn't know just how bad it was or was going to be until I started inletting as there was a lot of work to get the tangs inlet.

In hindsight I should have tried to return them when they first arrived (which I didn't realise was an option at the time), but with international shipping I would have been taking a big hit anyway. I was too mad with the quality that I just put them away so I didn't have to look at them. That was now about 3 years ago so not a current experience, so hopefully things have improved, but I am now slowly troubleshooting my way through the mess. 

I would have been better off with just straight unprofiled blanks. I paid a lot of money to essentially do all the work myself anyway.

It is very interesting to see others had a shared experience around the same time. Fingers crossed that is all sorted now.

Tom I would do a chamber cast.  CPA's seems to sometimes swiych reamers.  My first CPA in 38-55 did not have the long tapered throat that they said it would.  It had a 6 degree per side angle into the rifling which I think is just the SAMII chamber.  I also have two 32-40's from them with completely different chambers.  All were ordered as schuetzen rifles.  They do shoot, but they want different bullets.  If you can't find a Weber seater I'd do a chamber cast and try to come up with a custom bullet that needs little seating effort.

There is also another possibility.  I'm pretty sure that one of Jack's highwall seaters could be modified to work with the CPA action.   

Chris.
