How to make a bipod in 2 hours

Post by Archfile »

I posted this to AHN a few minutes ago, but i thought that some of
you don't go there, and it might make a start to the 'best post'
awards (if someone nominates it), so here is how I made a bipod
out of junk laying around at dads place.


I used the following materials:

15mm box section for legs (to length 2x)
3.5mm x 25 x 55 steel plate
15mm x 12 x 40mm steel bar
3mm screw and appropriate nut
1/4" nut
rubber (see photo)



Step 1
Two legs are required (in this case non-adjustable ones 1, using the
box section the two legs were cut off on an angle, placed together in
a vice andfiled until the two angles were approximately even

The other end was cut to length of the bipod (remember to take into account the
height of the rubber section - i forgot)

Step 2
Cut the steel plate to shape, and then silver solder, weld or somehow attach the
legs to the plate at the desired angle.

Step 3
Drill the 1/4 (slightly larger) hole in the center of the plate for the retaining screw.
Your legs are now done and you will need to either finish them off with an angle
cut, or weld or attach a threaded piece to make them adjustable for height.

Step 4
Now comes the annoyingly time consuming part, the retaining mechanism for the
bipod, which was inspired by the harris type that i've seen pictures of, take the
steel bar, center it in the lathe chuck, face off the front and make a 1/4" shank
on it to the desired length (mines about 1" long) and then part the bar off with
3/4" of bar ontop of the thread.

Take the piece and drill an 8mm hole (width of the sling stud) thru the bars long
side (you could use square bar if thats all you can find) and then remove the piece
to a vice, take a hacksaw and remove the top of the bar down to the holes to make
a U shaped hole (measure whilst doing this to keep it in tight tolerance)

File it to shape for smooth edges and such, then file the cut edges to create a flat
base and sides to the U shaped hole.

Step 5
Remove it and drill a 3.5mm hole thru the other side for the retaining screw, the
height of your sling studs will determine the exact dimensions of this retaining
piece so think before cutting/drilling.

Step 6
Thread the 1/4" shank for whatever nut you have around.

Step 7
Fit the retaining piece to the stock

Cut some rubber to fit around the retainer and place the rubber on the retaining
piece, run the thread thru the legs and place the nut on the bottom and tighten,
if all is well you should be able to tighten the retaining nut to finger tight (or more)
and still have some movement due to the rubber for cant and angle.

1) Will need to add a threaded piece for screw out leg adjustments)

Alpal, did you give it a go? I've since shortened mine about 1.5" and I'm very happy with it. I've knocked over a few bunnies with it now.

Some sort of adjustable leg would be good tho, the uneven ground requires some digging with the toe of the bipod to get a good rest sometimes.

Hu archfile,
Sorry it has taken a while to get back to you, but I have had visitors etc. No I haven't had a chance to make a bypod yet, but hopefully will sometime soon, thinking of using tubular steel so I can slide one size into the other for height adjustments, using a pin or bolt through holes in the bottom leg, similar to a car stand etc. to compensate for height and /or uneven ground. Will keep you posted as I go.

Slight update, went to Clarke Rubber and had a looksee, they had a 30mm rubber thing (looks like a door stop/food for a heavy piece of furniture)

The thing works perfectly, better than the rubber i was using, its one piece, and just the right size, was $2.95

Comp would have normally been closed today but no one nominated one single post. Out of all the useful info there is here I can't believe it. It's a little disappointing as we try our guts out and spend money on prizes to have no one enter comps :cry:

:roll:

I was hoping that another rifle bag was the prize, and that I was in with a chance, if only we could nominate ourselves :-)

Otherwise, I'd say either run another comp, or give the prize to the
article about the knife sharpener thing (i'm just about to read it, but
it looks like the author spent some time on it)

That author (GriMo) was donating the prize. GriMo is part owner of the site. :D
