New Shopsmith DC-6000 Dust Collector

[ssuel]

I ordered the upgrade for my DC3300 while it was on sale. Once I receive the order I will post back here. No idea if if or when it will ship. Glad I took a screen shot off my iPad at the time I ordered it because the confirmation email made no mention of my order number. Turns out the screen shot of the order number did me no good by trying to use ShopSmith website to enter my order number and zip code. My credit card has a hold pending amount so I guess I will only know via my credit card notification of when it ShopSmith actually ships the upgrade kit

I will not buy a DC6000...because I don't need two machines and for that price I don't need better dust collection. I have lived with what I have (DC-3000) for many years BUT for the right price (<$300) I could get intrigued with an upgrade but only if I know exactly what I am buying.

What does more HP do for me if I am spinning the same fan blade. Would I get more CFM and if so how much? Don't make me speculate! Commit the details!.

I thought the response from engineering laid it out: it's the combination of the new impeller and impeller housing that give more CFM.

Given that those new parts all fit inside the old DC3300 shell, it seems to me that when the service parts for the DC6000 become available, it should be possible to buy the new impeller and impeller housing and connect them to the old motor/motor housing and get the increased cfm performance.

Now, before anyone says I'm speculating, we know the new motor housing connects to the old impeller housing (because a new impeller housing isn't part of the upgrade). So the new impeller housing will connect to the old motor housing. Similarly, the new motor connects to the old impeller (since a new impeller isn't part of the upgrade) so the new impeller should connect to the old motor.

Now that I have read it three times, I follow your logic and I agree...I think.

Hahaha! Only three times? Usually people have to read what I write more than that.

I did not interpret the letter that way. My interpretation might have been biased because in this case I think I know better. That combination must include the higher motor output. There should be no way for the old motor to spin the new impeller at 3450 RPM at any reasonable air density. Impellers have HP requirements and must be matched to motors that can meet those requirements. (Or exceed those requirements, for those thinking along those lines for this DC-3300 power thing.) An overloaded AC Induction motor is a bad thing. An underloaded one is merely inefficient.

All good points, David.

FWIW, the fan housing is a different PN.

I guess my questions were not clear enough. I sent an email response this morning for more clarification. I will post when I hear something back.

I too sent an email to CS with specific questions about the upgrade kit. I asked for the Upgrade Kit BOM as well.

I am about convinced that I "need" this upgrade. I was very skeptical when this thread started.

And I am at the opposite end of the spectrum! I was ready to buy it when I got the email, even placed an order, but canceled it when it became evident to me that there was no new impeller nor impeller housing.

If it turns outs the the kit does include the impeller/impeller housing (or a later kit makes them available) and increases the cfm of the DC3300 to the same performance of the DC6000, I will probably get it.

I am waiting now to hear what the cfm is with the 1 1/2hp upgrade kit installed. I am not yet convinced that Shopsmith reports it to be 600cfm. I think I have seen 300cfm somewhere. I also do not know what the cfm of my old DC is. In one of the old catalogs I think I read 150cfm.

If 330CFM is what I have and 600CFM results with the upgrade - I'm in.

DUH..DC-3300 or DC-6000

I debated this for a while and then I caved.

Now I wonder! How can a brand new item, recently marketed for the first time, be out-of-stock.

This has become a waiting game. Just thankful I don't really need it.
