DC-6000 poor performance

[RFGuy]

I posted this in the video description of the last video shared by RF Guy: Contact Doug via email at: douglas.techno.smith(AT)gmail(DOT)com and let him know that I sent you and that you are interested in a download of his catalog of 3D products, as well as the STL file for the chisel guide.

Awesome! Thanks Scott...

Thanks to both of you.

Scott, I do have the STL for the chisel sharpening guide, which I got when he posted about it in the Shopsmith Owners Facebook group. I'm the one who commented on your video that I, coincidentally, also printed it in green but my print warped slightly so the bottom wasn't flat. I have an official sharpening guide from Shopsmith, so I was printing Doug's mostly as an exercise. I didn't realize Doug offers a whole assortment of 3D printed items, so I will reach out and see what he's got. Thanks for passing along his contact info.

RF Guy, thanks for the link to the Oneida hose and the MGR video. I thought I've watched nearly all of Scott's videos, but I'm pretty sure I haven't seen that one. The Oneida hose you linked is the one I had found yesterday, but it's nice to have confirmation that it's the correct one. I'll be back in the shop a little bit later today and I'll see how I make out with the 8' plastic hose. I suspect I'm eventually going to end up buying the 12.5' Oneida...gonna take a minute to talk myself into dropping another $75 (for a HOSE!) though.

One more question: in your testing in the other thread, did you or Dusty ever check if there is a difference in airflow between the various ports of the 3 way port? I would assume the left and right ports are probably very similar, but perhaps the lower port might have a different level of airflow(?)

Thanks again for everyone's help.

I included the Oneida link to help because like I said you want their 2.5" vacuum hose, or at least that is what I have been using. Yeah, take a look at this post linked below. On my DC-3300 at least, the center port performed the worst. Left or right ports were near identical and gave the best airflow on that 3 port manifold. The measured data from the anemometer is airspeed (ft/min) and then I have to calculate airflow (CFM) based on the dust port aperture size. That post is fairly descriptive, but if you have questions don't hesitate to ask.

I had looked a that info before but not closely enough because I hadn't noticed you gave the specific airspeed at each port. Thanks for pointing that out. I know now that in addition to the restriction my hose was causing I was also using the least effective opening of the 3 way port.

I also realize I worded my comment about the Oneida hose poorly. What I said might have implied that the hose you linked is the hose I found yesterday. What I meant was that the hose you linked was the same listing I found yesterday. When you first mentioned the Oneida hoses I went Googling and came up with the same link you shared. Thanks for confirming I found the correct link. (The physical hose I found seems to be an original SS black plastic hose.)

Shopsmith kinda implied with the DC-6000/DC-3300 upgrade kit that it could better support airflow for having more than 1 port open on the 3-port manifold, e.g. when trying to simultaneously collect sawdust from more than one tool at the same time. So, I took data with 1 port open (other 2 closed), then 2 ports open (1 port closed) and then all 3 ports open. You get the highest airflow out of it with only 1 port open and for me, my 3-port manifold is best on the left/right ports. Dusty replicated my measurements using his anemometer and his upgraded DC-3300 for comparison against mine. His results disproved the Shopsmith marketed claims on both points, i.e. it didn't reach rated performance and it degraded substantially for more than 1 port open just like a non-upgraded DC-3300. I point all of this out just to emphasize that several things were being presented in that data. Hope this clears it up.
