Sadly, on Castor I do not have that little post/penis thing,
Maybe Castor is Castora?

Idler shaft bearings the same as quill bearing. (6202-10 rr) == 5/8" id x 35mm od x 11mm width and rubber seals) X 2 bearings/shaft.
FWIW I think of it as an arrow!!!! The end more closely resembles an arrow point. :rolleyes:

Castor been castrated? muuuuuuaahahhahahahhaaa! Russ said it's a 520 carriage, my guess is the 520 doesn't have the post/penis/arrow shaft and latch setup. I had a brilliant idea while I was working on my 1959 Ford tractor. In the back where the three point hitch goes is a top link. It's threaded with one end right hand and the other left hand so it can get longer or shorter as needed for the implement. I might try to use a lightweight top link for the drill press that I can easily spin up or down attaching to the bottom of the table/carriage and the frame below. It could be on a clevis so if needed can be removed completely. This will also provide added support for heavy stock that I'm drilling and pressing down on with the quill.
I just ordered four 6202-10RR for Pollux. Hoping the Mark VII doesn't give me any grief on that. Hey, I was thinking, I could swap headstock motor and get the blower setup on Castor. Wondering if the motor will come out with the headstock on the ways? When I'm in there doing bearings would be a good time to swap if it's not too hard. Really want a vac system on Castor. I might call SS on Mon and see if they have a motor lying around and the vac hardware maybe hidden in a closet in the janitor shack. Maybe

The motor and pan are secured with 4 or five screws. The belt cover needs to be slid back. IIRC, THE SWITCH AND POWER CORD GO WITH IT.
I predict they will say a Mark VII ?????

As JPG predicts if you call Shopsmith and ask for parts specific to a Mark VII they are going to ask Mark VII what???? Then they will ask do you mean Mark 7? Which you do not. Remember the Mark VII was last made in the 1960's and not only by a different company than the current makers of the Shopsmith tools but in a different location with several moves in-between.
I do have to ask why do you want a working dust collection system on Castor since it is going to mostly be a Drill Press for metal? I would understand if you were going to use it for woodworking but sucking up hot metal fragments will only tear up the impeller. As someone who restores Shopsmith back to as new as possible I would want to have all the original parts working but for actual use, I would not want metal going into a dust collection system.
As for your comment about the lowest speed available the Speed Reducer may be the answer and JPG might know if it can be used on the Mark VII. I believe it could but am not positive. That would give you a 7:1 speed reduction.

Speed reducer oughta work. Way/bench tube spacing the same as is the quill fitting.
chapmanruss
The only possible difference I thought there could be is the height of the Spindle/Quill above the Way Tubes not being the same as a Mark 5/V.

:D I'll call em just to confuse them. hehehe. I wouldn't be picking up hot swarf with the built in vac, and - having seen the 'quality' of the impeller you are spot on that it would be reduced to junk in short order. But - after it's cooled I try to keep a clean floor. Despite some pics showing leaves in the hangar, I do keep a pretty clean shop. FOD and aircraft bits don't mix well. I have a large shop vac now, but any added vac facility near the tool would be quite helpful so I don't have to get the big barrel vac out, and then put it away. More-over, if I have something that is supposed to work, I would like it to work fully, and not just half-assed. SS back in the 60s touted the MK VII as having a vac system built in, so darn-it, want it to work as designed.

The Dust Collection built into the Mark VII has everything going through the impeller before being deposited in the bin. Any metal or other "stuff" besides wood dust being picked up will damage the impeller. Even properly used it will wear over time. It is simply not made for shop cleanup kind of work. The Shop Vac deposits what is picked up directly in the container before it can travel through the filter and impeller.
docmirror
Sigh, ok - no swarf then. Is it ok that I still want it to work right? Maybe collect some dust, or Dust? I'll use my big canister vac to clean the shop.
JPG
YA, so add a dust deputy or some other 'separator' ahead of the MVII vac input.

Well - I called Shopsmith today, talked with a nice lady. First I had to explain what a 'Shopsmith Veee Iiiii Iiii' is and not a 'Shopsmith 7'. She said ''ooooooooohhhhhhh, I have never seen one but heard about them. Asked for vac bags, and she asked if I had a PN. Why yes, yes I do and I give her the PN. She says yes, they have vac bags FOR A DC3300 dust vacuum. Lolz. I asked about a few other bits for the Mark V, and they had them or could get them. She advised ebay and that was the end of that - haveaniceday. I'm gonna take my duct hose to a vacuum place and measure the box size below see what they can do for me. And, I remember, 'no swarf'.
BTW, I found the black tubes to fit a table extension and fitted one of them. Pretty nice work surface.

Black Tubes ???
docmirror
Black pipe, about 8 inch long. Goes in the side of the table, and the knurled knob tightens down on it. Then slip a table ext on and do the same. Pretty cool. I didn't take a pic, will be down there next week and update.
JPG
Oh 3/4" iron pipe.
The MVII ext table has posts that go there. Same posts that fit into the aux table holes in the end bases.
docmirror
I have to respectfully disagree with JPG. Pipe and tube are used interchangeably, but they are not the same. The product I have is not iron it is steel and it is not used to convey liquid, or gas, and is not rated on a schedule like pipe. I'm going to stick with 'black tubes'. I used pipe when questioned, but they are definitively tubing. I've used a ton of pipe and some tubing in my career, so mixing up isn't a big deal but the ones I have are tubes.
I got Pollux apart for belts and bearings and I found the dragging problem. the intermediate shaft bearings inside the eccentric are trashed. One is almost seized, and the other is shedding bearing balls - which, is not conducive to smooth operations. Will rebuild it and stuff it back together. The quill and main bearings were in very good shape, and just cleaned and left in place.
JPG
OK! They be tubes. Not commonly found laying around.
I hope the idler shaft is OK!!!! I have one that the bearing trashed the shaft.
Hope thee greased the bearings after cleaning!
docmirror
It be ugly in there. My belts arrived today. Pollux will be back online late next week. I'm headed to CO for some vacay skiing.
I have to take the motor out to get the aux shaft and sheave out, then press the bearing off and new ones on. Not too bad of a job, but the belt routing and removal/install is wicked. Very tight tolerances forming the belts around stuff.

Well, delays happen. I have a vacant rental and I'm' stuck with some int renovation this week then off to see grandkids over the wknd. I have all the bits I need for Pollux, but not the time to dig in. I found some flex vac hose that seems to model what the Magna did with their vac hose and bought that. I also stopped at a vac repair place and asked them about a dust bag for industrial. They had a catalog of various sizes, so I need to measure my canister on the bottom and see what will fit down there.
My next task on Castor is to refurbish the -- castors. It rolls funny, and doesn't turn or run smooth on the ground. I almost tipped it over trying to move it with the whole thing tipped up for drilling. I'll set it back horz and then set it on the ground sideways carefully so I can get to the castors and clean and lube. Won't be for a week or so until I get the rental house done and the new tenant moved in.
BTW, I offered my bro-in-law Pollux after I get it sorted. Don't know if he wants it, but it may be making a road trip to S TN as he is mostly a woodworker and would put it to better use.
