My attempt at Joe's router

[DayneInfo]

On my Sosylva I used my router table and a 45 degree bit. I just cut the entire length a littl at a tim. I think I did something like 3 passes. That way I did not have to worry about a notch.

My cnc can't move that quickly either, or I wouldn't have my fingers near it. I cut my finger with a utility knife yesterday....left that off the list also.

In my years of fabricating wood and metal professionally, I have many first hand stories of people that maimed and even killed themselves with machines. I guess I've been lucky. The only permanent loss of a digit was 32 years ago in welding school and it was only partly my fault. My left thumb is now a little shorter than the other because the bench grinder rest was not adjusted correctly. The welding lab instructor should have taken care of that to protect us stupid kids from ourselves.

One thing I've learned is that to save your fingers you need to stay on your toes. I can pull my hands out of any cutting operation in the blink of an eye.

Didn't really mean this to be long winded, but it brings me to a safety point I don't think many people that come here and build machines know: WEAR SAFETY GLASSES AT ALL TIMES IN THE SHOP! The pros know this, but many people that come here and want to build a machine, or even just casual woodworkers, don't realize how important this is. That video of the little girl staring at eye level at the router cutter was just flat scary to me.

Sorry to hear about your finger, your teacher should have been more careful. I was brought into woodworking in woodshop with absolute safety at all times. If my teacher back in the day saw you using a machine without safety glasses he would hit the estop to kill power in the entire shop so everyone got pissed at you. It was engraved in me to use guards and pay attention at all times. I trust tools to do nothing more than perform a task but I do not trust them to mind my personal safety. Free handing on a router table is different than holding down material on a machine with a mind of its own. Sure it's highly unlikely that you will hurt yourself, but it happens, so why take the risk? I do a lot of dangerous stuff and work with dangerous machines every day. But I prepare myself every time so that if I slip or I fall I'm never going to have my fingers in the path of the bit, knives or blade. When my CNC is done I will probably wear glasses when cutting at all times. Just be careful guys, no piece of material or job is ever worth hurting yourself.

Well I thnk I now have a Joe's wannabe in my shop. I finished the assembly as far as I wanted to go then tore it down. I did notice that I am going to have some issues with bearing contact on the x axis rails. It is apparently something I cut, the good news is that it seems to be a problem the full length of the axis. Hopefully this will make it easier to fix. I also want to point out that I HATE to paint. Did I say HATE...well that is what I meant. So I went for my special " half arse" look. I am proud to say that I accomplished it. I have to pick up some extra bolts that I want to use then I will start to put it back together. I think I need to clean the shop first, it is becoming a problem just moving around in there. I think I also need to decide where it will live its life out, this is not something I want to be moving around to get it out of the way. I have a spot in mind but will think on it for a few days. I still have to order my lovejoys and decide what to do about motors.

Looking good Dwayne.

Is there a reason you are putting your y axis motor on the opposite side?

If I hold a piece down in a jig that constrains x and y in a cnc it is extremely safe. The spoil board constrains the z- and the only force left for me to constrain with my fingers is z+. Since I only use straight flute or down spiral bits, the z+ forces are minimal. Don't take this as just some handwaving threoretical explanation. I have cut many hundreds of parts this way since I got my machine running and it works well. I will switch to dedicated vacuum jigs as I can.

I work with dangerous machines everyday, but try to never do dangerous stuff.

You should make it a habit to wear eye protection from the time you enter the shop until the time you leave. You will consider cutting your finger trivial compared to blowing an eye out.

Totally agree with you.

Well..er...uh...I dunno. That is where it is at on my current router. I never noticed that it was on the other side on Joe's machine. Now I feel kinda stupid. But hey..I can change it, or leave it I guess. Nothing permanent yet.

Dwayne

[Madclicker]

shouldn't matter.

[David Da Costa]

No shouldn't matter, just put them on the side that is going to be the most convenient for cabling.

The only thing that you may have to do is just reverse the Motor in Mach3 settings, because depending which side the motor is on it will run in reverse from other side.
