Project Update (2/27): The Router and Router We Get
It was time to play with the new routing table. Here I'm running just a spare piece of plexi through it to test. I'm routing through with my trusty Bosch upspiral straight bit. It's the same one that I used in my RotoZip.

You can't beat the smooth, clean finish this bit leaves behind. Just look how smooth it carves out the plexi (the cut on the top right.)

I bought a standard straight bit by SKIL, but it doesn't even compare to this upspiral. It wasn't carving clean.. it was causing the plexi to foam and melt around the edges. So I took it out and threw in the Bosch upspiral, and all is well again. :up:
So what are we doing tonight.. well, we're doing a little rework. I know, I know.. no one likes to do things over, especially me. But as goes this project, so goes a good part of my time, money and.. well, life, basically. I've invested a lot into this work, so if an opportunity presents itself to make a part of it better, then I will.
In the last update, I showed how the bottom shelf in the Zero Gravity Chamber was buckling a little due to the weight of the SSD shelf. We were able to remedy that by making that bottom shelf out of 1/4" plexi instead of the 1/8" that was used originally. In addition, the original mount for the SSD shelf was very simplistic and rather ineffective. It was a straight join with weld-on, and while it will hold okay, there are more effective ways to bond two shelves together.
So tonight, we're going to explore a better way of joining the Zero-G shelves together by cutting and routing some 1/4" plexi to replace the 1/8" plexi that's currently in the chamber.
Here I am marking the SSD shelf location.

Where you see the shelf rest, we'll be routing a groove out in that bottom shelf for it to fit snug in. Here, I'll show.

I've set my depth at 1/8". Remember that we're not carving through the shelf but just routing a groove out for our SSD shelf to fit snug in.

The depth of the rip fence on this table is too shallow, so I had to remove it and replace it with an aluminum angle positioned far enough back to route a little more than 3 inches into the shelf.
Here's the end product. A nice, clean straight groove cut into our shelf.

That turned out really well and was a lot easier than setting up a straight edge and cutting with the RotoZip. Having a bench just allows you better leverage, along with square cuts.
So, now it was time to cut a new SSD shelf in 1/4" plexi to replace the 1/8" piece. Time to crank up the new toy.

My new Ryobi table saw with 30 in. adjustable width to the right of the blade.
I moved it into the back corner of my shop next to the routing table.

It was fun using a handsaw to cut this stuff until it became difficult to make square cuts even with a straight edge. The Skilsaw kept getting hung in the plexi which would cause it to drift a little.
I admire anyone who has both the patience and skill to use hand tools for everything, but my philosophy is if there's a better, quicker, more precise way to do something, then that's the way I'm going. And this table saw will save me a lot of headaches and a lot of time. I'm doing a lot of work with plexi in this build and will in future builds as well.
The thing I noticed immediately with the table saw was how simple it was to square off a piece of material. Two of the four sides of my plexi sheet were not square because of the Skilsaw drifting, and I was able to correct that in a matter of minutes.

Ok, the first test... how well can it cut through not just plexi but tougher material, like solid state drives...

Anyone want to take a guess?
:)
I'd have to be out of my freaking mind and then some, obviously.
No, what I'm doing here is measuring off that SSD shelf, because I'm going to cut the new shelf to the same exact size.

We'll be cutting right along that line for our shelf width.
And away we go.

Notice that I'm feeding the blade while standing to the right and out of the kickback path. Important safety tip for anyone who's doing this for the first time.
And after what seems like far too easy a job, we're through. Here you can see the nice, clean cut it gives us. I'm using 180 tooth 10" Irwin blades made for plastic and plywood.

Ok, retrieving our shelf that we had routed the groove in before...
http://img199.imageshack.us/img199/9978/dsc14110001.jpg
And we'll slide the new SSD shelf down in that groove..
http://img203.imageshack.us/img203/310/dsc14080001.jpg
Voila.
We'll secure the two pieces with weld-on. This should give us a cleaner and more secure bond than just bonding two flat pieces together.. especially with the more sturdy 1/4" plexi. :yepp:

And, using our old SSD shelf as a template, we'll mark the drillholes for the new shelf...
http://img199.imageshack.us/img199/1484/dsc14180001.jpg
And those will be drilled shortly.
Thanks for reading; that's it for tonight. Time for me to clean up some of this plexi dust before I get caught in a blizzard.

Safty First When NOT to wear gloves!
It's good to see you enjoying your self mate.
However your not being too safe!!!
Please get ride of those damm! gloves when using power tools, you scare me.
If by chance(and God forbid) your wearing your gloves and you slip or just have your hand in the wrong place and the sh@t hits the fan.
The teeth on the saw blade will grab hold of the fabric/leather of the glove and pull your whole hand into the blade as fast as it can look at you.
There will be, no time to react and it will not stop until either your hand jams the blade and stalls the motor
or it cuts through your hand up to the point where the glove stops, only at that point will you be able to pull your are away.
That might well be past your wrist, I am really serious mate.
Look at it this way mate, if you stuff up with NO glove on your hand there is no fabric or leather for the teeth on the blade
to grab hold of and pull your hand into the saw blade, so you loose a finger, no biggy, you have more, right. :rolleyes:
It will only cut your skin, I know sounds dumb, but you will be able to pull your hand out, straight away, as the blade will have no hold on your skin.
Because it has already cut it, just like how you can cut into a piece of wood and stop when ever you like.
As long as you don't push the wood towards the blade anymore, there in nothing for the blade to grab and pull on, it just sits there.
I have seen some pretty horrendous thing happen at work over my time, I touched on that with the drill press at Shazzas work log.
I lost the top pads of my two middle fingers on my left hand thanks to a wood plan, luck for me I just touched to top of the blades and it flicked my hand back, but didn't grab it.
In fact it wasn't until I noticed what the wood was suddenly wet, my first thought was that sap coming out of 100 yr old Jarrah.
Jarrah is hard wood from Western Australia and it’s red in colour, so then I looked at my fingers.
The blades had cut off the pads at the tips of my two fingers, ring finger was to the bone and both had lost the tips of the fingernails.
I hardly noticed it, just a quick sharp pain, like a splinter.
After 6 months the skin finely covered the flat spots back up and I got full feeling back in both fingers, you couldn't even tell unless you look real close now.
I pray that all close calls are that easy to fix. :yepp:
Anyhow!
When cutting on a table saw, yes there is a chance that material can kick back at you.
Mainly with wood that has a twist or a bow in it, and for that reason you should not use it.
It kicks back at you either because it gets jammed between the fence and the blade or it rides up the back of the blade.
The splitter at the back of the blade will stop most of the kick back as it stops the material from touching the back of the blade.
You are right, you are best to stand on the right side of the blade with a table saw.
But don't push material through with your hands, use a push stick made out of scrap wood.
This will not only keep your hands away from the blade but will also help to stop you from leaning over the blade as to push through the material.
Plus don’t think that guard over the blade will stop your hands either.
It want, it's just cheap plastic and it will break up when something either hits it or will lift up as your hand slides under it.
I don't want to scare the crap out of you so you never use it again, but just give you the heads up that these can bite.
Take the time to ask people that have work with this equipment what the best way to use it and what do you need to watchout for.
There will be locale courses you can take or just buy some book on how to use it.
Have fun with it mate. :up:
