Does everyone use carbide drill bits? I've been having trouble lately with then for some reason. It's weird. The internet machinist talk how great they are for their job, but I'm seeing a lot or variation in their performance in wood. I wouldn't think that would happen, but something is happening. Anyone else having trouble with carbide bits?

Anyone else having trouble with carbide bits? I took my Goatboy Drill Jig and a body blank to a local woodworking shop to find drill bits. I showed the owner how the jig worked and he was kind enough to let me sort through the drill bits he had in stock to find some that fit nicely in the jig. I found 4 bits and they are not carbide. The are just plain old steel wood drills. With a good pin vice, the drills work great. Is anyone reaming the axles holes after drilling?

I am not reaming. When I first heard about reaming holes from 44 to 43 I thought they were just using a 43 drill bit to get there. Tried that with disastrous results. Learned the hard way there are things called reaming bits with straight flutes to keep the hole straight. I might revisit the reamers.

Pony I have never had a problem with the carbide drill bit. In fact I drill 1000's of holes with them. check your drill press and see if there is any play with the spindle if it moves that would be the problem. your drill press chuck and spindle should not move.

I think you're right about the bad spindle. That drill press has an old spindle and I don't have trouble with the bits on the other drill press. At one point I thought it might be the way I drilled the blocks on that one drill press. On that drill press I use fences and hold the block down by hand. I did find I can move the spindle on that one drill press though. The drill press is old. On my Craftsman drill press I had to shorten up the working distance to get rid of play in the spindle.

So you still drill bodies with a drill press, as opposed to the fancy new jigs everyone's raving about?

I still enjoy the drilling. Sometimes I think there are advantages in drilling your own cars. I've learned much about how these little cars steer and stay on the track.
