Oh the sacrifices you make when producing a video.
That’s a beautiful “scrap” piece of Cherry that I would LOVE to have and use my Ringmaster to make a bowl.
It is sad.
At 12:25, you pushed the headstock toward the tailstock to make it easier to lift to the drill press position and were able to use it at that height. At my advanced age, even my little 10ER was all I wanted to lift with the headstock all the way to the right (about to be down) but I couldn't fit my work under the spindle. I found an uncommitted hole on my headstock and an uncommitted slot on the end of my tube frame so I put a long-stroke, small diameter air cylinder between them. The correct air pressure on the rod end just counterbalances the headstock so I can put it all the way to the right and lift it up, then pressurize the cylinder and raise the headstock to the needed height. When I use the machine as a glue press, I have to raise the headstock frequently while it remains vertical so this was a needed addition.
The 10ER will only get down to 900 rpm so now I'm wondering if this speed reducer would fit it. I know I should upgrade the 10ER but I have $50 invested in it and it's my 3rd oldest machine so I want to keep it around.
Nice fix. On the Mark series SS sells the Lift Assist, which works quite well, but unfortunately it doesn’t fit on our 10er’s.
I picked up a used speed reducer a few years back. Now that I see it in action, I will have to put it to use.
Thanks for the instructions.
Glad to help
Excellent video, Scott. I did not realize that the speed reducer could be utilized as you did on the band saw.
This is not intended as a cheap shot but just a tip. I keep the way tube mount bolted to the output side of the speed reducer. It seems to me that the reducer is well supported on the input side as it is clamped to the quill. However, there is a lot of overhang on the output side. This really seems to help when in the lathe mode with a large or unbalanced blank.
Thanks for the tip!
A brand new speed reducer was included with the Mark 520 I bought. I wasn’t sure if I wanted to use it or sell it. I’m going to keep it now that I’ve seen this video. Thanks for another great one Scott.
Good call!
With my PowerPro all I have to do is slow the machine. Another good reason to upgrade. Great video Scott!
Exactly right! You have the higher speed range and none of your capacities are reduced. It’s definitely a strong case to be made for the new, smart motor headstock.
The Power Pro features are nice for that reason. The only caveat is the speed reducer can be found on the used market starting at $150 versus the Power Pro upgrade is $2200. I paid $400 for a 500 upgraded to a 510 with a bunch of stuff I didn't have and it also included a speed reducer. The cost is definitely a consideration, even paying full retail price for the speed reducer @ $500
@@TheVerbiousOne Absolutely! I mainly bought the PowerPro for the increased speed. I wanted a shaper, but didn’t have space for a stand alone unit. Since upgrading 5 years ago I’ve been absolutely pleased with the increased functionality.
I have a speed reducer and have never used it. I have never thought of using it on the bandsaw.
Very timely explaination guven those FB comments! And now i see why, even with the PP i need yet another accessory! Great demo as always, and looking forward to that lathe work!
GREAT VIDEO!!!!!
This is some great content.
I have both the Speed Reducer and Speed Increaser and while the concept is sound, putting Theory to Practice is sometimes confusing.
Thanks Jody. I’m glad you like it. See you tonight? Scott
I got a speed reducer to use the shaper 15 yr ago , it is still in the box. Some day i will learn to use the shaper, maybe?
Speed Increaser? The speed reducer would be horrible at shaping.
I think the Speed Reducer engineering is really cool. Is it stout enough to bear the 12-inch sanding disc?
For sure. Next weekend it will be stout enough to support a 12x12x4 block of maple.
Looking forward to the lathe turning. I'm interested in the speed reducer due to the high lathe speeds when turning, shakes like crazy. I wouldn't consider turning large items in the current condition, don't have the PowerPro.
I’m with ya.
Scott: GREAT video! Since I got the Power Pro, I rarely use my speed reducer, and wasn't sure how to hook it up with the band saw. I look forward to the next video.
The speed chart used for the conventional headstock shows a speed of A-B for drill bits over 1 inch diameter which would give and RPM range of 700-900. The Power Pro Gen 1 menu shows a recommended speed of 400 RPM for a Forstner bit between 2 and 3 inches.
I estimated the speed you used after you dialed it up to be around 600 RPM. (It looked like you were at the"I" setting for drum sanding). Did you happen to check the speed using your "crapometer"?
No, I didn't check, but I could. It's funny how SS was so inconsistent with their instruction. I'm assuming that they were written by two different product managers.
I’m on the fence about trying to pick one up. Like anything with SS, it feels infinitely cheaper to just buy a second SS that includes the thing you want :). But I haven’t yet seen any nearby listing with a speed reducer. I do have a few that have a Power Pro gen 1 upgrade though, so internally debating if it’s worth the ~$1200 for a 500 w/ the power pro…
You aren’t alone in that strategy. I see folks posting on the Shopsmith Facebook group, some of their finds, and I’m just shocked at how low some sellers are willing to go with PowerPro Mark 7’s. I am assuming that they are typically estate sales. Scott
The clamp can be turned in either direction. I found sometime I wanted it one direction.
It’s a heckofa good SPT.
Hmmm... Makes me think I shouldn't have sold my speed reducer when I bought my Power Pro headstock.
Nah, you really don't need it.
Nice video Scott. You’re going to cost me more money! 😂
Sorry about that, Albert. See you tonight?
@@MyGrowthRings Scott, I’ve been trying to email you. I didn’t receive a response, so we extended our stay in Asheville. I’ll email you again with a #.
@@alberttreado3713 I’ve been conducting training all week and haven’t been on top of my emails. I’ll check it out.
When you muscled the unit to vertical, I didnt see you IMMEDIATELY(in one fluid motion before you forget) lock the hinge - to prevent accidental fall back. Must have been edited out.
Ha! I NEVER lock the drill press lock. I've even done a video about that.
It's mentioned here: ua-cam.com/video/_u_MBZlFdHQ/v-deo.htmlsi=l69TM3_aAf6NMV-P&t=163
Great Video Scott!.
Two questions are stuck in my mind.
7:00 When doing the alignment, why would you not put the drive spur back on to work with the two points aligned to each other?
9:45 it appears that the coupler is at an angle. Is that a video artifact or are the two sides of the speed reducer not at the same height relative to the way tubes?
Both very good observations. There’s no reason why you wouldn’t put the drive back on, I just didn’t. And no, you will see that I moved from one side of the machine to the other while getting everything in alignment. I had the clamp pushed too close to the bandsaw initially,but straightened it out off camera.
@@MyGrowthRingsAhhh! So, would you recommend connecting the two ends before finally tightening the clamp, or is that too many moving pieces? (Yes, I have a speed reducer in my arsenal but hadn't thought of moving it to the other end)
@@tigger-5652 Exactly right.
So, Shopsmith makes the speed reducer, but I failed to find the speed increaser on their website. Is that discontinued?
Yes, actually, both have been discontinued, but have been produced in small runs. I don’t know what the plan is today for the speed increaser, but who knows, it could come back. Scott.
@@MyGrowthRings I have an opinion/cheap shot. The speed increaser was conceived before powerful routers became available for $100 new. Speed increaser is the expensive way to do the job. Running (old Mark V) full tilt puts maximum stress on the system and never achieves anything like modern router speed - according to Jacob Anderson (SS repair expert).
@@archived_turkeys6487 You get no argument from me on your assessment of the Speed Increaser, but that isn't the topic of this video.
At time 9:50, that coupler seems very misaligned.
It was. You may have noticed that there’s an edit where suddenly I move from the back to the front of the Mark. That’s when I noticed that I clamped the reducer base mount a bit too close to the bandsaw. Good catch.
Another slow, boring video! ~LOL~ Thanks as always for for the great information, Scott.
#ISeeWhatYouDidThere
What if you reversed it... to increase the speed? Like for shaping/routing? Not that you need to do that... But don't routers run at like 20-30K RPM?
Good thought, but unfortunately the way this was designed it wouldn’t be able to withstand the load that is put on a spindle when routing and shaping. Also, you are correct that most routers run in the 20,000+ rpm range.
