Drill press?

The school doesn't have one, and none of us have one at home. But we managed anyways, with a table, a clamp, three different drill bits, and 10 minutes.

Here's a good one, and it's cheap!!!

AlphaTauri might actually want the drill press not just the table portion of the drill press.

Yeah that might help. it's the way that the drill comes straight down that makes it good for straight holes, not the table.

There's only one left in stock! Order fast or you might miss it!

One in stock to match its one star.

If you do need a full drill press on the cheap, Harbor Freight is usually a good bet. This one looks to be their cheapest: http://www.harborfreight.com/cpi/ctaf/d ... mber=38119

If you don't need to do a ton of stuff, just a 90 degree mount for the drill you probably already have would work just as well. I have a Craftsman one, but other manufacturers have one: http://www.craftsman.com/shc/s/p_10155_ ... ccessories

Or you can make do with lots of clamps, whatever works.

A team mate of mine got these hollow handballs which are basically smaller raquetballs. Has anyone seen these before and or know if they are usable in competition?

It probably depends on the State and how picky the event supervisor is.
A raquetball is 57mm in diameter and ~39.7 grams
some Handballs vary around that range and may be easy passed off as raquetballs
Squash balls are much smaller (39.5~40.5mm) and weigh 23~25g. These are not likely to be accepted.

Again, it depends on your individual competition (or you can submit a clarification with the risk of having it denied and alerting the event superviors that they need to pay special attention and measure the balls used)

Personally, I wouldn't risk it.

Good Luck

The projectile is provided by the student and should be a Tennis Ball, Racquet ball, ping-pong ball or plastic practice golf ball.

It would be close. I wouldn't risk it all because the price of disqualification is not worth the reward of a high placement. Try it if you have an invitationals left, but have a back-up ready just in case.

And let me say now for the record, you don't want any part of those plastic practice golf balls.

Yup. We have a whole cabinet full of the things (and I have no idea why). It seems to work pretty well as long as the person drilling is competent with power tools.
