best way to drill holes?

I am going to be doing a buggy spring set up in the near future, and I was wondering how everyone goes about drilling holes in the springs to secure them to the frame? That metal is really hard to drill through, so I just wanted to know if anyone had some easy or easier way to do it. Thanks in advance.

Two things come to mind, slow drill press and lots of oil.

Re: best way to drill holes?

Fred,
I feel sorry for you....when I was drilling the holes in my springs for the teflon pads I ate up 6 drill bits and never got a single hole done. I am lucky in that I have access to a HEAVY DUTY punch....you know, one of those 12 foot tall scary machines that will punch 2" hole in 1/2" steel....worked great on the springs.....

Do what John says....but you might want to try to find a really hard drill...not you local Craftsman...Also, make sure you drill a small pilot hole...you may even have to drill it several times going up a few sizes each time.

Good Luck

Re: best way to drill holes?

They last post talked about a hard drill,you might want to find cobalt drill bits.They can go thru anything,they also come with a very flat angle at the tip(135degrees)witch helps as well.

Re: best way to drill holes? - The secret...

Masonary drill bit - sharpened slightly with a grinder. Lots of oil (Tap-ease is niiiiiiice). Take it slow. And a drill press makes life MUCh easier (but a hand drill *will* work.
You will have to re-sharpen the bit a few times during the process, but it works, I swear...

Re: best way to drill holes? - The secret...

I did this for a friends CJ. He told me where to put the holes and I cut them with the YAG Laser we have at work. No cutting oil, no messed up drill bits, and it took about 20 seconds per hole. Check for a local Big machine shop in your area, if they don't have a Laser, they will know someone who does. Find an operator who is into 4x4's and he'll probably do it for free!

I think that the underhood Premier Power Laser has met with some governmental regulation problems - something about accidentally turning on while in traffic and cutting a few cars in half at a stoplight.... I may be wrong though [img]/wwwthreads_images/icons/tongue.gif[/img]
