How to cut nice round holes in rubber mat
I need to cut 4 nice round holes, maybe 3/8" in a rubber mat I have in the bed on my 35 Pickup. I need to tie down a trunk, but do not want to cut holes in the trunk or the bed, so I am using existing holes in bed floor and using tie down straps. I am thinking of using a hole punch, sort of like you would punch holes in a belt, but a larger hole of course. The mat is almost 1/4 inch thick, so that is going to take some doing. Thinking also about chucking up the 1/4" hole punch in a drill and trying it that way, but have some misgivings about that method. Of course, just drilling it wouldn't work very well either. Looking for other suggestions to make nice smooth hole in the mat. Need to cut 4 holes all together. All suggestions welcome. Thanks. Lawson

Re: How to cut nice round holes in rubber mat
how about using a piece of pipe and hitting with a hammer, and putting a block of wood behind the mat

Re: How to cut nice round holes in rubber mat
Use a 38 caliber spend casing and put a block under it and hit it with a hammer. May take more than one to do all the holes.

Re: How to cut nice round holes in rubber mat
There are these fabric/craft stores, like JoAnnes and Michaels in California,
where I had to make similar size holes in thick card board, they sell these metal tube cylinders specifically for cutting various materials that are chamferred on one end and are razor sharp, looks almost like a hollow punch, and you hold it in place with your hand like a nail and whack it with a hammer a few times till it cuts all the way. I was glad I asked a clerk and explained what I was trying to do, it worked out great, and the cutter was cheap, not more than $7. |

Re: How to cut nice round holes in rubber mat
I agree with Henry in Kokomo. I use a steel pipe of appropriate size, chamfer the edge, and smack it with a BFH using an oak block for the backer. Works slick, costs pennies and saves a trip to the store. RPM

Re: How to cut nice round holes in rubber mat
The whole set of gasket punches is fairly inexpensive, they will do a good job on thick rubber, I have used them when making Jeep body mounts. ..B.

Re: How to cut nice round holes in rubber mat
The steel pipe method works fine, when I was working on golf carts I made thousands of washers for the battery holdowns with a sharpened pipe fitting for the large dia, and a gasket hole punch for the small dia ---in 1/4" thick scraps of mat

Re: How to cut nice round holes in rubber mat
I use a Gasket Punch Set #1270 that I bought from General Hardware Mfg. Co. Inc., New York, NY 10013
The punches look something like sockets that are very sharp at one end and have a hole at the other end to mount a handle that can be struck on the end with a hammer. The punch sizes range from 1/4" to 1". Sometimes when I punch thick rubber I set up these punches to work in my hydraulic press. If I'm punching large holes or large gaskets, I make a punch from a section of pipe and mount that cutter in my hydraulic press. Whenever I use these punches I always back up the material being punched with wood.

Re: How to cut nice round holes in rubber mat
Thanks for your input fellows. I am leaning toward the hole punch or hollow punch idea. I have done that before, just looking for input from others. Trying to get some better way if it is out there, I will need to sharpen up my hole punches though, or use a bigger hammer. LOL

Re: How to cut nice round holes in rubber mat
I've also used hole saws to make some rubber pads about the size of hockey pucks. I cut these in my basement shop on a drill press and the smoke that it made filled the entire house with the smell of burning rubber. The little wife was real happy about that ...Not!

Re: How to cut nice round holes in rubber mat
Hole saw or 4" exhuast pipe,file the leading edge sharp and place a block of wood under the mat and maybe a piece on top of the pipe and hit with a big mallet.Or if you want to stink up the shop get the end of the pipe cherry red and it will melt right thru like butter with a nice clean hole.
