Shopsmith Speed Reducer for Lathe Turning
Вставка
- Опубліковано 5 жов 2024
- SHOP NOTES: The Shopsmith Speed Reducer takes the slowest speed of the conventional headstock from 700rpms by 7 to 1 to 100rpms, which is perfect for turning large objects on the lathe.

The ONLY ( NOT!!) comment I have:
There are handles available that replace the set screws. They add a world of convenience to turning.
The speed reducer is interesting. I took mine apart to get an idea of how it works. Pretty ingenious.
After fighting the Shopsmith version of the St. Vidas dance I used one for quite a while. The reducer is a gotta have. I have the PPRO headstock now but before? I used it a lot.
Excellent video!
John, yes, this one used to have handles and I replaced it with set screws! I prefer the set screws because the handles always seem to be in the way, even though they are adjustable.
@@MyGrowthRings
Well, hmmm. Hmmm.
On occasion yes - well - kinda quasi frequently - but - but!! It’s worth the removal and relocation.
By the way - what kind of thread is used? It’s a common thread size I know but the handles are kinda difficult to start and do not turn easily, a good attribute. That said I wonder what is the magic. Are the handles ever so slightly oversized? The tap ever so slightly undersized?
@@johnrice6793 No, it’s tapped to 5/16”. Should fit standard fasteners.
@@MyGrowthRings
The thread is of “normal” size. I’m always surprised how tight fitting the tread is. I wonder if there’s some type of tap that makes the tread tighter than normal.
@@johnrice6793 Could be, but it’s unlikely that Shopsmith would have ponied up for such a tap! Perhaps they’ve added a dab of Loctite to the threads?
Wow I’m just beginning to learn turning. I’ve watched Nick Engler’s beginners video several times.
It's a fun activity, but it's something I haven't done much of lately, other than teaching my grandkids how to turn. Have fun and enjoy the journey. Scott
Little-known trick about the lathe rest arm at 8:17! I've been a ShopSmith owner for over 40 years and that's the 1st time I've seen that. I've had a few thin blanks where that would've helped...
Keep in mind that this is only on the Mark V 510 (1985) and newer, due to the larger space between the way tube and the mounting hole in the larger carriage.
Turning is so mesmerizing and relaxing!
I really used to enjoy it and wish I had more time to play.
Just saw this because I saw your Q&A so I went back and watched.
I don't do much turning but I want to and I will eventually.
It's on my list.
Great video.
Thanks for circling back!
I’ve been watching for a pre-owned speed reducer for a while. They don’t show up often and sell fast. Eventually one will show up. Thanks for the video.
You are right about that! The one thing you do need to keep in mind is to make sure you buy one that is pretty unused. There are a couple poly-v belts inside that will stretch out overtime and can be damaged if the owner doesn’t keep them tight.
This is my first to see a speed reducer. I need one.
You’ll love it once used. It’ll remove the angst associated with turning. It really is a game changer.👍👍
I’ve already stolen the set screw! You make me laugh. But a great video!
Using the Powerpro, so no need for the reducer, but a mechanical headstock would definitely require it for turning. Going to a scraper at this point…it will take forever! But you have the makings of one nice bowl, whenever you choose to complete it. Nice video.
Thanks. I'll get back to it shortly and will likely post a pic somewhere. Scott
Scott, just remember it might be 10 where you are at but it's 5 o'clock somewhere.
True
Great demonstration, Scott. My Shopsmith shook like crazy with smaller out of round / balance turnings. The speed reducer is on the " should have list".
Thanks, Brad. It was kinda anticlimactic, though. I was sort of hoping for a disaster when I ran it without the reducer installed! Was that wrong?
Brad, my name is Ellis Reeves and I have a SS speed reducer that has never been used. Bought it from SS, but before I got to use it, I bought the Power Pro headstock. Also bought the speed increaser at same time, it was used only 3 times. Maybe we can work something out.
Scott, thanks for the video. I have a Mark 7, so speed reducer doesn't do much for me. Seeing you moving the post position on the tool rest was new me. This past week I have turned my first projects. What a learning curve. It was a lot of fun and looking forward to doing more in the future.
This is surprisingly long journey, but thankfully it’s a lot of fun.
Good job. Looking forward to seeing where you go with the bowl.
Me too, Mark. I’ve got a crazy schedule, and that was all the time I had the dedicate to this. I’ll get back to it soon.
I have turned small items, but nothing large. I watched it done long ago on a Shopsmith without a speed reducer, and it scared me big time! If I ever decide to get into the larger turning, I will have to get or build a speed reducer. Maybe someday, I'll be blessed with a Powerpro.
That's the ideal solution.
Good video. I haven’t tried something that big since I threw a chunk of walnut into the wall. I have the speed reducer will give it another try.
It really helps. Why weren’t you using it?
@@MyGrowthRings That is why I bought it, and using the drill press on metal I think even if I updated my shopsmith to a computerized unit, I would still keep it.
Out of balance blanks are very common for wood turners. Your blank was not as out of balance as some I have turned, but still shows how much vibration they create if the lathe is rotating too fast.
I have turned pieces where the grain density was not even, light in one area and dense in another. This was frustrating since the imbalance continues even after getting the piece round. Just have to fight with the issue all the way from turning to sanding.
I hope your screws come out without breaking.
I have the same Hercules Hunter carbide tool. I do not use this when roughing down the blank, it is too bouncy.
Dave.
The Hercules was taking me for quite a ride! Normally, at that point, I would’ve reached for a scraper, but I don’t have a good one on hand. I’ve turned a little bit of pissy, wood, and even some warm wood, where I had to add a couple washersunder the head of the screws just to add some weight. Yes, not thrilled with those screws. I normally use Spax panhead screws.
Nice, bro! Turn that into something pretty for your bride!
I’ll do my best.
Need to get me one of these...and the increaser.
Do it.
What a difference with a speed reducer.
Question on technique, why not use a roughing gouge to get to the round?
A roughing gouge is ideal for spindles, but not so much for bowl blanks. Roughing gouges are quite aggressive as end grain comes around on the bowl blank.
@@MyGrowthRings good to know, thank you.
Thank you!
Thanks for watching and commenting, Albert.
Nice Demonstration. What kind of chisel did you used first? I couldn't see well.
It's a Hercules Hunter No. 3. See it here: huntertoolsystems.com/product/3-hercules-tool/
Hi Scott ... I loved seeing your set-up errors so I might make less of them! Thanks! I need the Universal Banjo ... did you get yours with the machine, in the aftermarket, or new OEM after machine purchase? Thanks, John (P.S. ... I guess subscriptions lapse or are cancelled ... I've resubscribed!)
My tool rest is the stock version sold with the 510/520 model. The Universal Tool Rest is sweet, though. Lots of cast iron.
Another great video! Did you make or purchase your compass? I like the looks of it!
I made it from a plan that was either in Wood Magazine or Woodsmith, if I recall correctly. It has served me well for many years. Scott.
@@MyGrowthRings Thanks! I have the libraries for both of them!
Woodsmith, Issue #69, page 22. Thanks again!
@@stased7343 Excellent. Thanks for looking it up.
This seems much safer than starting at a higher speed.
For sure.
I assume the speed reducer is not needed for the Mark VII?
That is correct of the modern “Mark 7”, though the 1960’s “Mark VII” would benefit from it.
I would like to know what the tool is called, and where I can buy one that you used to draw the circle on the maple blank?
@@flywelder I made it myself and it is called a compass.
You should have hand spun the blank before you turned on the power to make sure you were not going to bind.
Yeah, I might have if I wasn't sure of my sawing and faceplate positioning. I knew I was good, and had it hit the tool rest that would have just added a fun topic to the follow-up video! Scott
😂
Hey Scott I’ve messaged you a few time and you’ve given me some great info. I recently got a Total shop on Marketplace and I’ve been using the Lathe. I would like to make some bowls and cups and stuff but screw the blank to the plate like you did but the blank keeps flying off the face plate. Can you offer me an advice or recommend some chucks I can buy?
@@FrankPugliese-p5f What’s been failing, the screws or the wood? As for chucks, it all depends on your budget. Some of the top of the line chucks would be the One Way Stronghold: amzn.to/3xPd1GM or the One Way Talon: amzn.to/3xVFPx5 which is a smaller chuck. Both of these would require an adapter like this one: amzn.to/4buNWOV. There are several inexpensive knock-offs available, and I own a couple. The Wen is fine for getting started amzn.to/4buNWOV
@@MyGrowthRings I might have an adapter with the box of stuff I got with the total shop but definitely not the chuck. Thanks for the recommendations and for getting back to me. I can’t wait to make a bowl!!! Lol
@@MyGrowthRings the wood flies of the screws but the face plate stays on the machine
Well your tools were sharp at least 😀
At least for some of it. I edited out the sharpening breaks.
Who's going to ask to see the DIY speed reducer try turning?
There’s no support for the spindle. The DIY reducer uses the spindle of the headstock and the SPT as the upper spindle, so there’s no way to attach turing equipment.
Once the blank was balanced and you increased the speed, what was the RPM? Where you still under the 700 low end of the plain headstock?
That's an interesting thought, Tom, but no, I only sped it up to "H", which is normally 1600 rpms, but through the reducer that makes it 229 rpms.
Hey Scott this is Henry and I use my Mark 5 (I purchased in 1981 or 1982 )to turn bowls and I was wondering if you know where I might get a speed reducer used at a good price ,I can't afford to buy one from ShopSmith I'm disabled and living on a fixed income .Any suggestions would help
You best bet is to keep an eye on eBay, Facebook Marketplace and Craigslist. You might need to buy a complete Shopsmith system that includes a speed reducer and sell everything off that you don’t need.
What is the reduction ratio? Example: At 700 rpm on the dial what is the output of the reducer?
It’s about 10-1. Paint dries faster than the spindle turns.🤓
On slow the spindle turns about 70 rpm. The reducer is a heckofa, “gotta have”. On fastest speed the spindle turns around 700. Sweet!
