• Scam Alert. Members are reminded to NOT send money to buy anything. Don't buy things remote and have it shipped - go get it yourself, pay in person, and take your equipment with you. Scammers have burned people on this forum. Urgency, secrecy, excuses, selling for friend, newish members, FUD, are RED FLAGS. A video conference call is not adequate assurance. Face to face interactions are required. Please report suspicions to the forum admins. Stay Safe - anyone can get scammed.
  • Several Regions have held meetups already, but others are being planned or are evaluating the interest. The Ontario GTA West area meetup is planned for Saturday April 26th at Greasemonkeys shop in Aylmer Ontario. If you are interested and haven’t signed up yet, click here! Arbutus has also explored interest in a Fraser Valley meetup but it seems members either missed his thread or had other plans. Let him know if you are interested in a meetup later in the year by posting here! Slowpoke is trying to pull together an Ottawa area meetup later this summer. No date has been selected yet, so let him know if you are interested here! We are not aware of any other meetups being planned this year. If you are interested in doing something in your area, let everyone know and make it happen! Meetups are a great way to make new machining friends and get hands on help in your area. Don’t be shy, sign up and come, or plan your own meetup!

Must have hand tools?

Centre drill the hole and you get a chamfer to keep the drill bit from wandering.

Drill press definitely - cordless I have done that - it’s easy to snap off the tip though especially with the smaller sizes. And then you have a nightmare. It Has to go in very straight.
 
I was making a exhaust shroud for my sand muller today and pulled out my set of Cleco pins. Very handy. Basically lets you drill/align two pieces of metal before you rivet/attach them together.

See video here: Youtube - video on Cleco
 
That would be nice, I pour out the sand on a tarp wet it and shuffle it around until it is mixed a muller is definitely in the cards, ironman on YouTube has a good video on his he used a microwave timer to set his.

Is one better than the other? They suggested the one circled in green, I’m used to using the one circled in red for spotting holes
 
center (re) drills work well if you only drill the little hole, but tnot the 60 degree part. Even professional machinists get that wrong. A centre (er) drill is primarily meant for drilling for a 60 degree center... when you use it for a 118 degree drill, your contact area is on an edge, and if your flutes are a little out, it will pull the drill out of line. Sometimw waaay out of line. Using a 118 degree spotter drill for a 118 degree drill is ideal.
 
Center drills work fine. If I remember my schooling correctly the spotting hole should only be slightly larger in diameter than the chisel tip on the drill bit you intend to use. That way it traps the drill point just enough to get the lips cutting. As noted a proper spotting drill would be ideal but then again the budget comes into play! The center drill can do double duty.

Picked this guy up today at a local machine shop. $10 cash, we were both happy.

No idea on the brand, it’s got WTC #4
HSS USA
written on it. More than good enough for me

I borrowed a buddies drill press to drill a bunch of holes in aluminum angle. I don’t have a drill press vise or fancy riser blocks, so I made up a couple pairs of riser blocks from what I could find in the shop :D
