anyone know of a tool that would cut a round hole on a rubber strip?

Its for a truck car-flag bed rail project I'm working on.

They are typically cut with a punch. What size do you need? A shoe repair
or leather shop may be able to do it for you.

Use a round tube of the desired diameter. Chamfer the inside or
outside diameter (your choice) so the remaining material forms a sharp
edge. Place the tube with the sharp edge on the rubber strip. Use a
BFH to smack the unmodified end of the tube, not your hand, and your
done.

I don't have the actual size of the hole, but its the usual 5"x5" L or T
brace with pre-drilled holes that home depot sells. the strip is 2"W x
36"L x 1/8" thick and haven't cut to desired length which is 1"W x 5"L.
(i'm wondering how I'm gonna cut it nice and even, prolly with a sharp
knive and ruler I suppose).

Is gorilla glue sufficient for bonding rubber to metal?

If the hole is small, make a punch out of steel pipe as others have
suggested. If large use tinsnips. Medium holes can be cut and rough
edges can be ground off with an angle grinder if you have one. If you
have a lathe, rubber can be machined, use a high speed and cutting
oil. It can be drilled too, again using high speeds and cutting oil.
Be sure to fasten down securely.

Also rubber can be cut with a hand saw, jig saw or bench saw so long
as the teeth are sufficiently fine and non-tungsten carbide. Be
cautious though, it can pick up and get dragged into the saw slot. It
depends on the type of rubber and the temperature. Better when it's
cold.
Soapy water lubricant helps.

Holesaw (type tfor electric drill) works well too. Again soapy water

I don't think OP ever said what diameter he was looking for. If it is
bigger than what a HF punch set can do, you can use a piece of tubing or
a tin can of the correct diameter, an sharpen the top edge. Easy on a
lathe, if you have access to one, but you can do it with a hand file or
grinder wheel. If the rubber will be hidden in the final project when
installed, the cut doesn't have to be perfectly round. If this is a
one-off use a cardboard template and an exacto knife with fresh blade,
or sandwich the rubber between thin plywood sheets and use a drill to
just make a circle of small holes to define the diameter.

Lotsa ways to do it.

If the rubber is clamped between two plywood sheets any hole saw would
work, you could use a knife to cut around the inside of the plywood
template (miss-cuts will only be on the waste side of the hole
perimeter, unlike using a can), and any edge cleanup could be done
with a drum sander bit in a drill or a rotary tool while the rubber is
still sandwiched between the plywood.

I don't think the OP writes clearly. But best I can figure, he's using a
strip of rubber between a standard L or T bracket, and whatever he's
bolting it to, which seems to involve trucks and flags. I *think* he
wants to cut screw clearance holes to match the holes in the brackets.
In which case I'd suggest a sharp drill, using the bracket as a
template. OP seems to be struggling mightily to do what appears to be a
simple project, albeit one not quite simple enough for him to actually
articulate.

Hey, everybody has to start somewhere with tinkering, and unless this
contraption flies off at road speed and causes a wreck, more power to
him. I agree this seems like a trivial project, and most of us (even
ones like me without a proper shop setup) could probably dive into our
junk box and McGyver something in short order.

Laboratory workers for years have used sharpened brass tubing sets for
drilling holes in rubber stoppers. The best lubricant for this job is
plain water. Any thin rigid tubing will work on rubber, like a piece
of 3/8" hydraulic (brake) line, whatever. A regular drill or similar
is hopeless. G. Shumway has it right.

the reason for the bolting is I'm having 2 braces of the same type
clamped together to increase thickness.

the home depot braces are about 1/8" thick, doubling that with another
brace increases that to 1/4" thick.

Originally, I was going to put the brace in between the car flag window
slot, but saw that this wasn't going to work as the car flag would have
tilted angularly outward instead of straight.

I've since used a hose clamp to bind the flag stem & brace together
keeping it straight up.

I'll concede that I could have just went with 1 brace instead of 2 brace
& bolts and slap a rubber strip over it without any need for making any
holes.

problem right now is finding the right kind of clamp to bind the brace
to the bed rail. I've been told that a camper or tonneau c-clamp would
do the trick, but its looking more likely that a tie-down clamp maybe
what I'm looking for.

Are you trying to find a way to fly a flag from the vehicle, and in the
case of a pickup truck, from the top rail of the bed? So one leg of the
bracket bolts to the vehicle and one leg bolts to the stick from which
the flag flies?

If that's the case, I guess part of my problem was that I was
envisioning a lumber framing L bracket, and what you're envisioning is
what I'd call an angle bracket.

How big a hole& how thick a rubber strip?
this is the 2 braces I'm testing. I've noticed that the hole sizes are
different between the 2 braces.

L-brace
http://www.s10planet.com/forum/attac...8&d=1292824309

Home Depot was out L-brace, so, I wasn't able to measure it other than
the one I had at home.

minimum hole appears to be 1/4" or 6mm, the counter sunk holes appear to
be smaller than 5/16" or approximately 7mm as its bigger than 6mm and
smaller than 8mm. the #10-24 x 1/2" machine screw flat head is a
little too big. not sure what flat head machine screw will fit in
there. I guess I could make the counter sink hole a bit bigger. I
understand that there are counter-sink bits for certain types of jobs.


T-brace
http://www.s10planet.com/forum/attac...9&d=1292824465

the minimum hole size fits a 1/4" or M7 machine screw , the counter sunk
hole is about 5/16", didn't check metric on that one.

M7 is actually the better fit as I could screw in the sample bolts.
Unforgettably, I couldn't find any M7 machine screw to compare with the
1/4" machine screw at Home Depot. 1/4" screw (I forget what type screw
it was) turned out to be a little too big, I tried #10-24 x 1/2" machine
screw, its flat head fit better.

sigh, I found a bad screw in a pack of 8 screw/nuts; its threads are
stripped. 7.5 out of 8 ain't too bad.
is it possible to debur this or just a waste of time.

the bending issue isn't why I did what did. the issue is with the car
flag in how its made. At the base of the car flag, there is a small
clearance about 3/8" distance between the end of the base and the flag
stem. the car flag needs to be level and even on the bed rail side.

the 2 1/8" braces and 1/8" rubber strip will even out that space to 3/8"
total thickness.
