I have a couple stocks and forends that need to have cuts on them and I want the cuts square with the stock and do not want any angles. I have a chop saw with a 60 tooth blade and a an old saw table combination where you put a piece of wood in clamp it down and the saw rides inbetween two upright poles with guides on the front and back so basically the saw blade runs true.As usual any help or comments. One forend is for a BSA single shot 22rf target rifle.The end towards the action the cut is neither true 90 angle and the cut is angled off to one side. If you are familiar with these rifles the gaps are apparent. Frank

I personally would use a different blade, a freud tk806 is my blade of choice. Basically a 10" 80 tooth that burnishes. The freud Diablo 80 tooth is similar and acceptable.

Anyways, if you don't know, you should cover the stock in masking tape where the cut line will be, it will reduce or eleminate splintering. As per getting it square, bout the only way is eyeball it.

I use a couple 10" mitre saws and the blades mentioned above are good ones. I only use 60 tooth blades for rough work. But, I also have a dandy 12" disc sander and that is what gets the nod for final truing of an end cut.

For your BSA I’m afraid that trying to nibble it square with a chop saw carries significant risk that you’ll make the situation worse. I would tackle this problem with a file and some 80 grit sandpaper on a sanding block.

You might want to are a rasp to the above mix and take it slow with all.

Almost nothing on a regular rifle stock is square or easy to chop.

As others here are saying - you are better off chalk fitting with hand tools it to get rid of gaps

If we’re going to introduce files and rasps, better share a bit of technique. When cutting end grain always try to cut supported fibers. If you cut from the outside of the piece of wood towards the center, the fibers are supported. If you cut away from the piece of wood the outside fibers are unsupported and you’ll likely tear away chunks of wood creating a bigger problem.

I doubt that you have a rasp, but if you go looking you’ll come across another tool called a micro plane. They cut very fast, probably too fast for this job. If you try just remember to cut supported fibers.

I have a ton of tools, and I’d expect to start and finish this project with a sanding block.

Use our chop saw and the finest cut blade available. Select a dowel rod slightly larger than the barrel channel and tape it in place so it extends a couple inches each side of the cut line. Wrap a couple layers of tape over the desired cut line and mark the line. Place the dowel against the saw fence and cut.

If using a chop saw you will have to support the end of the stock so you have a 90 degree angle to cut. Otherwise the stock, being tapered and not square, will end up with an angled cut. This will have to be laid out, every stock will have a slightly different taper.

I made a Long Wooden Miter Box with both 90 degree and Angle cuts to cut both the stock and nose caps to match.
I use a Hand Back saw to do the cutting and finish the pieces off with a sanding block.
I place the stock in the Miter box, and shim it and clamp it so the cut ends up Square both directions then clamp it in for the cut.
Yea, I am OLD School.
But it has worked for 30 years, so why buy power equipment when I only do a few stocks with Nose Caps a year.

I have had pretty good luck using a miter box and fine hand saw i just buy a dowel to approximate the barrel and line that up instead of stock as most stocks have a taper.

The barrel channel is about the closest to true on a rifle stock A wood dowel taped or bolted in and used for alignment with a level. a long stock inletting screw used to hold dowel in channel that sticks out will give the other axis. A small level on the dowel and stock screw will get them very close then clamp to fence solid and check alignment. cut slowly and carefully. A layer of masking tape with a deep knife cut on edge of cut saves a lot of splintering.

Use a deck of cards to level the stock for the cuts. Add or subtract cards till the stock is square.

I cut wood stock forends (front & rear) in a miter box with the barrel channel "down" on a flat surface that's squared to the cutting blade.

I use sacrificial tapered cedar house shingles on the sides of the FE to ensure that it's also squared to the C/L of the barrel channel.

The angle, in relation to the barrel, should come out correct every time.

The angle @ the rear of a forend would have to match that of the receiver face against which it will abut - especially if the face of the receiver was specially coutoured out of square as a design feature.

Do have a electric miter saw with a 60 tooth blade. As well as the hand miter saw. Someone years back posted a jig he made up where the barrel channel was face down on a jig he made up with the center top of the forend was laid out with a straight line facing towards where the cut was to be made and used tapered wood wedges (or the tapered wood shingle wedges) and the line mated up with a corresponding line on the jig. Getting back to the BSA forend, looks to be cut down from another forend. And the section that faces the front of the receiver does not come up square with the face of the receiver. Only needs about 1/4" taken off and I can make up a dutchman doweled and glued in place. Not a wood worker by any means but can do something like this. Gotta see what pieces of walnut I have in my small stash. Never ran across a 10" miter saw blade with anything more than 60 teeth. Thanks to all of you who took the time to respond to my post. Your comments and suggestions are greatly appreciated. Frank

This stock was Sectioned on A Miter Box with a Hand Saw.
The forend was cracked and Greese soaked, so I just replaces it with a piece of maple.
It is a Mosin nagant stock that I sporterizes since it could not be restored in the condition it was in.

Bazoo, where would I get one of the TK 806 80 tooth 10" blades?. I have an el cheapo table saw that I could make up a jig using the channels in the bed for alignment made up of wood to fit the channels and glued and screwed and take a cut so that the edge closest to the blade is square.

LAGS, very nice joints. Have a couple stocks that were done years ago. One of which was a 1917 enfield stock. Higher comb,pistol grip and was made for a '17 with the straightened trigger guard. Got it for nothing except all my '17's have the standard trigger guard. And while I'm at it what do you all use for glues?. I have Elmer's wood glue and that is the only adhesive which I have experience with. Frank

This stock was actually glued up with Elmers wood Glue.
But a lot of my stocks I do with Epoxy Died Black or White with washer spacers to give a White or Black line separation between the two different woods.
This stock was Salvaged and reshaped to be used as a pattern to run on a Stock Duplicator.
But even glued with Elmers, this stock is currently being used on a 1891 Mosin Hex receiver rifle, and has held up really good.
I also make wood blocks with holes in them that fit inside my Mitre Box, to use as drilling Fixtures to be able to use the old cleaning rod hole as a place to Dowel the two pieces together on Military Stocks.
For installing a nose cap on New stocks, I use two 3" drywall screws threaded into the stock, the head is then cut off leaving a threaded stud about 3/4" long .
Then the nose cap is drilled for a slip fit over the studs, and then the cap is epoxied on.
The slip fit on the studs gives you a little alignment wiggle room.
The epoxy fills in the space around the threads and works like rebar keeping the nose cap in place forever.

If your saws have the depth of cut you need You could build a jig on a piece of plywood with a straight edge that will go against the fence on the saw. You can then attach blocks to the plywood with 2 sided carpet tape and nails or screws to the plywood to hold the stock in place . You have the fence side to measure from to give you a reference line to square the cut with the barrel channel, a piece shaped to position the barrel channel would be attached centered on the line.
Make the plywood base longer than than the miter saw base so a stop can be attached to the bottom to repeatably position the the jig on the saw , the bottom of the other end can be shimmed to set the angle of the vertical cut.
This sounds a lot more complicated than it is the cut angle is set with the piece in the barrel channel and the shims under one end of the jig the rest is just to stabilize while you make the cut.
Is this clear as mud.:p

Rule of thumb: it often takes a lot more time to create a jig or a fixture in order to make one precise cut than it takes to actually make the cut. Welcome to the world of precision joinery.

Good quality 10" blades are offered by all the major woodworking stores. Google is your friend.

For putting on a nose cap, I will make my measurements, draw a line over the stock, and use the bandsaw table to keep things squared up for a 9o degree cut from the barrel channel. Then I go to the sanding disc to give a perfectly flat gueing surface. YMMV.

One of my first joinery tasks was to extend the butt on a ex military Rem 40x rimfire stock. Actually had to make up a walnut dutchman to fill in the handstop channel. Small block plane until it almost fit. Then sanding carefully until it required finger pressure. elmers glue applied with a brush and in she went. Used four of those screw clamps with the soft pads. 24 hours later then used the block plane to get it as close as I dared.Then it was a matter of sanding flush. And made up the dutchman for the butt with wood dowels. Used some scrap 2"x4" and some threaded rod as a clamp. Why go to all this trouble??. Cause my Rem Sendero with the 26" barrel fit the factory inletting perfectly.Definitely agree that making a jig to work off the table saw takes more time than it does to cut the stock. My crappy table saw doesn't vibrate much when in use. Put the sanding plate on and add the sanding disc and you can watch the vibration move the saw. Think a trip to the lathe is in order to true up the plate. Only have one gun shop in town and he has an arangement with another smith for all his gunsmithing. So I do what I can with what I've got. And thanks to all. It continually amazes me the breath and scope of knowledge the members here have. Frank

I use a Dewalt chop / miter saw with a 100 tooth blade. Have done numerous nose caps and an untold number of recoil pads. Set up & stability is everything. Shim, measure, shim & measure again. Wether you are changing the butt angle or just shortening the LOP, sporterizing the fore-end, take the time to get it solid and then step back. Is it right? If so, then a firm, slow, steady speed cut will get it done. Good luck.

Was on the Fruend website last night and they have a Diablo 10" x 90 tooth blade and reading the hype says the cut comes out like they used 220 sandpaper. And almost burnished the wood as its being cut. Price isn't as bad as I would thought it would be either. I have a few older mauser stocks that aren't good for much more that firewood so I'll use one or two doing the cuts as if it were real. Since it's a 10" blade can be used in either table saw or mitre saw. Frank

Place the dowel against the fence, not the stock. The dowel is more or less parallel to the bore axis for the 4 or 5 inches involved and will produce a cut that is square enough for joining stock sections under a band and more than adequate if just shortening the fore end.

Actually the whole idea of asking how to do a cut started out with a BSA 22rf martini that had a non standard forend. Instead of the long style used on a model 12 or 12.15 it looks like it is a stevens forend because it has that short section up front that would have a barrel band. The other day when I originally posted this thread, found a 1903 Springfield "C" stock that had been cut down to eliminate the part where the barrel band used to be. Stock is in nice shape and would be a shame not to use it for my sporterized 1903A3 with a lyman 57 rear and I hope to find a lyman 17xnb globe sight to replace the redfield sporting front sight. And maybe add a short section of rosewood to the end of the forend. I don't hunt anymore as I have mobility issues so I think I'll glass bed the action and first inch of the barrel and leave the rest free floating. I always enjoyed the excellent wood working skills by the members here. Some of the stocks are truely remarkable. And again thanks for your suggestions and comments. Frank
