Getting a start on the details...15

I took the SawStop off the old dust collector and onto the new system. A 5" duct reduced down to 4" at the machine.


The switch over also made a big difference in keeping dust and chips to a minimum. The 2nd hose goes to the blade guard which in my opinion doesn't work as well as expected. I'm not sure what I was expecting, but when you have a vacuum within the blade guard, you would think that there would be nothing left on the table after a cut. So far, the little bit of cutting that I have done hasn't been as clean as I thought it would be.

The old Harbor Freight dust collector had to have it's screen removed to keep up with the saw dust. I didn't attempt to use the blade guard with that collector since it was barely keeping up with just what comes out from SawStops measly dust under blade hood contraption in the cabinet below.

SawStop has always been that way, on every machine I've used anyway... a less than stellar performance and this is no exception. I've had to vacuum out that cabinet several times before removing the screen in the HF bag collector... but the Oneida seems to get it all, until you make a cut with the blade guard dust collector in place. That's when you expect more from SawStop and again... get less.

I will say one thing about this newer SawStop design... it's easier to get under the cabinet with the door now on the left. The one piece plastic trapdoor seems to be a better fit than the old steel wobbly door on the right that wouldn't stay closed. When it was on the right side, it was much harder to get in and work on the underside.

In those days the cabinet would completely fill up with sawdust no matter what you did. We had a better dust control motor outside, but where it fell short was the 4" steel pipes running under the floor that frequently got clogged. I don't know if they were rusted out or not, they just didn't work as well as this Oneida system with it's ducts getting larger the closer it gets to the main collector.

I'm sending the old dust collectors to the Sunnyslope campus as Mr. Franklin plans to start a wood shop class down there too. Although the bag style dust collectors allow fine dust through which settles everywhere in the room, it is still a good starter for setting up another wood shop.

Getting a start on the details... 16

The router table has two blast gates so it can work from two directions, one below and one above. With a quick test, it works really well, but I only made three cuts, so the best way to see will be when someone uses it more. I might try reshaping the can to spread/fan out and speed up the suction, but I'll have to have another can to put it back if I don't like the way it works.


***UPDATE*** 5-28-18 I had a chance to work at the school this morning and took another tomato can with me. I made a rectangular wedge from a 2x4 which served as a starting point for reshaping one end of the can, flatten out the circle into a rectangular shape that better fits where it is located. Having two shapes will allow this to change back if necessary.



With all other blast gates closed, the two open gates on the router table should provide enough vacuum to keep the area spotless... I hope. Of course as more blast gates get opened, that air movement will be lessened but hopefully it will still work the same.


Very little left to go now. Can you tell that I'm sick of breathing dust and cleaning up the mess around the machines? It's not that my students don't help clean up, but it is all the stuff that gets missed over time which slowly piles up in corners and under machines. I'm a realist. I know there is no perfect system and there will still be some cleaning up... just not as much... I hope.

5-22-18 Something came from Oneida by UPS... well actually two things and they were both wrong. I'm disappointed because I want to wrap this up and someone mixed up the order. One package was for someone in Oregon and the other had 5" hose when it was suppose to be 3" hose. Now when I called, I suggested that their mistakes had also cost me when I had to buy 3" clamps again, to which they responded by telling me they would work on getting a refund for that and the UPS package for 3" hose came over my e-mail, so hopefully after school is out I will get a call from the school that it arrived. But as it turns out, when it gets here I may not be in a hurry to cut it up for the scroll saws. More to the story coming up!

I forgot to mention... School's Out for Summer!

WE HAVE SOME VERY GOOD NEWS TO SHARE!

We got the 2nd grant!


I saved this news for until the check arrived. Now I am re-establishing the quotes since this took longer than 30 days to complete. Once that is finished, I can begin purchasing a new band saw, now upgrading to the one with the brake and the 220v motor.

In addition, there is five Jet scroll saws, a Jet belt disc sander, a helix head planer, and since the competitors have a few lower prices here, and few there, I'm divulging bits and pieces here and there to my possible dealer choice... trying to drive the costs down. A call to their JET representative will let us know who is willing to play ball.

I don't think I will end up dealing with my 2nd choice dealer. If I start asking questions, I'm betting they will not be as easy to work with. For one thing, when I go to their website, it is refurbished equipment. It's a few more miles out of the way too. My 3rd choice is actually the closest to us, a mere 90 miles away.

Whom ever it ends up being, the shop.... will be forever transformed... by these private anonymous (not state or federal government) grants... and that is a very... very good thing.


It's kind of funny that this thread started as a way to share project ideas only to end up being a running log of activity on building a school wood shop at a school that doesn't really have the money to do what we are doing. I hope you are enjoying seeing what we have been working towards, even as I begin to think it's almost time for me to retire again. Physical things as you get older can really bog you down and that's what is happening to me.

If you haven't taken the time to look back at some of the updates I have been making to each post, then you are missing out on some really great stuff. I figured out how to make links within this site, that will go directly to each post. Slow connections or Internet speeds might require a little patience to load, but using the back browser arrow brings you directly back to where you left off reading. For example.... here is a direct link to the crankyman automata post and the back arrow brings you back here.

These links help clarify or point out ideas without a lot of fumbling around on your part. Now this makes me wish I would have made the posts smaller, concentrating on a single concept/issue/project, but doing that creates more pages. However, I could further direct teachers to these concepts in greater detail... so maybe some day I will be able to break it up into smaller sections. Doing this as an after thought would not keep them in chronological order. That order is part of what I think makes it more fascinating.... to watch a budding program thrive from day to day, week to week, etc... and work within the constraints of the times.

It's also too bad that DivShare has messed up their site. If any of you have been trying to get material on the broken links, let me know. I found my stash of material on one of my external hard drives, so I should be able to send them over e-mail. As I have time in the future, I would have uploaded this material to photobucket and remake the links, however, photobucket changed the free user agreement and I'm unsure as to what will work and what won't. Contact me so I can send material directly over e-mail.

Here are some general page short cuts for you...

A message to new wood shop teachers who may have stumbled onto this site!

Because of spam... this site has been closed for quite some time now, but if you would like to join, we could use some new blood. The older guys have been retiring and thinning out the ranks. I didn't ask permission to post this, but I found out from a new member that he did this to gain access.... Send an e-mail to tech@woodcraft.com I have noticed that this is helping new members get into the site while keeping the spammers out.


I've seen at least twelve new members have signed up since making this notice.
