Please don’t email or call until you have looked over the info I supply here. These are, as it is called, the most frequently asked questions and I still have people calling me and emailing these questions to me!! Argggggg!!!
What is your turnaround time on repairs?
I typically have 3 to 5 machines in hand in process. I like to work on just one a day, and I like to have a couple of days off per week, so my usual turnaround time is one week in my hands. Usually, this means that by the time you pay, work on your machine is done. I ship out in Tuesdays and Fridays so your machine usually will go out on that next shipping day.
How much does it cost?
Shopsmith Mark V’s have been made from 1953 until the late 2000s so their age spans over 50 years. An older machine, or one which was stored poorly or heavily used or abused could run over $400. A newer machine, one stored very well, and lightly used, might be a little over $300. See my pages called “Services and service rates”, “Examples of typical repairs”, “Return shipping costs,” and my web store for parts prices, to get a good idea of what yours may run.
Can I upgrade to a 2 bearing quill?
This is by far the most frequently asked question. People assume “more bearings equals better”. This is not necessarily the case.
I am not a fan of the 2 bearing quill at all. Since I have started repairing the machines as a specialty about 10 years ago, I have seen plenty of bent shafts on 2 bearing quills, always with a story about turning a blank or chunk of wood as the culprit. I can’t recall ever seeing a bent single bearing quill.
Yes, any Mark V can be upgraded. If you have a poly v drive, a 2 bearing quill can directly replace the single bearing quill. If you have a gilmer drive headstock, then you need to replace 3 other parts to allow for a 2 bearing quill. The drive sleeve needs to be converted from a gilmer configuration to a poly v one. The fixed sheave on the idler shaft has to be similarly changed out. And also the gilmer belt needs to be changed to a poly v belt. This typically adds $100 to the cost of your repairs using used parts. If your machine is 1985 or newer you have the 2 bearing quill.
Now, should you convert? SHORT ANSWER, NO!!! Mark V’s used single bearing quills from 1953 until 1985. Why did they switch, then? One of their competitors at the time went to a 2 bearing style, claiming it was better, and SS simply followed suit. It’s always been hype that 2 bearing is better.
You see, the back of the quill is supported by the drive sleeve (see photo above). Thus a single bearing quill is really a 3 bearing quill. Placing an extra bearing in the drive train merely adds more friction. If your bearings and components are all fine, I don’t believe you will see any difference between the single and the double bearing performance. In fact, in a 2 bearing quill, the inner bearing is the first to go in my experience. So I believe that there is no need to go to a 2 bearing quill.
This week, I have 4 machines with double bearing quills on hand, and 3 of them have bent shafts. I don’t recall ever seeing a single bearing quill with a bent shaft!
Save some money.
The rear spindle of the quill is supported by the drive sleeve component thus all single quills are really 3 bearing quills.
Should I convert to the 1-1/8 hp motor?
If your headstock is newer than a mid1962, you have the larger motor. Or if you bought your machine used, check the motor because some owners did change out their motors over the years.
Unless your motor is fried, I typically tell people to keep using their existing motor, whether it is a 3/4 hp or 1-1/8 hp. The original Shopsmiths, the 10e and 10er, did and continue to do fine with only 1/2 hp motors. A headstock with a 3/4 hp motor should do anything you want it to on a Mark V. As long as your bearings in the motor are good, it should give you great service. Changing bearings in a motor is a lot cheaper than buying even a used motor.
I have also read than the standards for measuring motors changed about the time Shopsmith went to a 1-1/8 hp motor, and that the new 1-1/8 rating is the same as the old 3/4 hp rating, so they may in fact be identical in energy output.
The motor used in Mark V’s is unique. You can’t just take any old off the shelf motor and put it in a Mark V. The floating sheave system for speed control requires a much longer shaft than is typically found on motors. Thus you either need to buy a used one (which may need bearings itself) or a new one from SS. Either costs you much more than taking care of the one in your machine.
About the only user who could benefit from a 1-1/8 hp motor over the 3/4 is one who owns the SS Mark V mounted planer (not jointer, planer). The 3/4 hp is fine for drilling, boring, sanding, lathework, sawing, and all the other SPT’s and add-ons made.
I also believe the 3/4 hp motors are very well made, better than those from the 1980’s on certainly.
Should I convert to the Poly V drive system?
In many ways the Gilmer system is superior to the Poly V system so if your headstock has a gilmer drive, I would keep it that way.
The quill and drive sleeve contact securely metal to metal with the Gilmer. The quill and drive sleeve meet with a sacrificial plastic drive ring assembly with a Poly V drive.
The “tank treads” of the gilmer belt are less likely to slip, although most have a force-activated clutch in the drive sleeve to allow for slippage.
Gilmer belts don’t develop a distortion from years of storage and they don’t wear out as quickly as the poly v style. Poly v’s can become distorted easily from sitting and have to be replaced for that reason alone.
Poly v’s also require more tension to prevent accidental slippage and that is harder on the drive sleeve bearings and the idler shaft bearing.
To convert from gilmer to poly v requires changing your drive sleeve and your fixed idler sheave along with the belt, adding to the expense of the conversion.
Poly v belt
Do you work on (Mark VII, Mark 7, Mark II, 10e, 10er)
Although I have worked on these other machines, I no longer do. I specialize in Mark V headstocks only.
You can certainly keep these other machines working with some work and ingenuity. The Mark VII has several parts which are no longer made. If any of these fail, you would need to get the parts from another machine, repair it yourself or have it machined by a local machine shop. The quill, drive sleeve, idler, control sheave and motor bearings are all standard bearings and are available from your local bearing supplier. You can make do with a Mark V poly v belt, and the drive belt is something you may be able to pick up locally. The electric switch would need to be modified and also the plastic cam in the speed control. The plastic rack the headstock moves on can be removed.
If all else fails, you can use a Mark V headstock on the Mark VII frame, you’ll just lose a couple of the functions (dust collection, reversible motor, shaper function).
There is no one currently specializing in Mark VII’s, but I wish someone would step forward to do so. I get a call every month looking for someone to fix a Mark VII.
For 10e/er service, contact Skip Campbell in Texas who is the leading expert on those machines.
What do you think of the new Mark 7 (electronically speed controlled) headstock
Not worth getting. These cost $1,800 or more just for the headstock. I don’t feel the electronically adjusted speeds help anyone other than woodturners. The speed range goes slower than the manually adjusted speed control of the traditional Mark V, which is an advantage to turning. But this does not help you drill, sand, saw or do any other the other functions better. For the same money, a wood turner can buy a very good dedicated lathe which will be of a proper height, a larger throw, and a longer bed. Also, the Mark 7 uses a password and you know how hard it is to remember passwords, and your family won’t be able to use the machine if you die and take the password with you. I also believe the combination of computer board and sawdust is a recipe for disaster. All of the early Mark 7 headstocks were rife with problems and it seems like they all had to go back to the factory. Maybe it is all straightened out now, but I wouldn’t spend that sort of money on this.
Is my motor fried?
Often, motor problems are caused by the bearings, belts, alignments and other problems in the headstock. Every bearing and both belts must be 100% so that things work right. To determine if your motor has a real problem, do the following.
Unplug and drop the motor from the headstock. Remove the drive belt from it so it doesn’t rub on the motor shaft at all.
See if you can rotate the motor by hand. Just because it can turn doesn’t mean the bearings inside it are okay. Listen for any scraping noises. The fan sheave can be rubbing or binding on the motor housing. If there is any noise like this, you’ll need to remove the sheave and investigate that first.
Now you can plug in again and try turning on the motor. If it kicks right on and works, you have problems inside your headstock.
If you hear humming but no turning you may have a bad capacitor. You can remove the capacitor and have it checked by an electric shop. (Note: some capacitors are internal to the motor). If the motor spins too slowly, bearings could be very bad and/or capacitor could be going out. If the breaker blows after a delay, it could be bearings.
If the breaker blows immediately, you probably have a short. This could be a short at the switch, in the pigtail leads, in the cord or plug, or it could be the windings inside the motor. You can see some of the windings in the motor from the air holes. If you see blackened wires, or if you smell a burnt smell, it is likely the windings. If it is the windings, you can have it rewired or buy new/used. All other problems are cheaper and easier to fix.
Is it worth fixing mine, or should I buy new/used?
It is ALWAYS most economical to fix the headstock you have, unless it is a total basket case like after a fire or flood.
The typical headstock repair is $350 to $400 plus shipping.
A NEW headstock from SS is $1,800 to $2,000 plus shipping.
A USED headstock will cost you typically $200 to $400 plus shipping, and it will STILL need at least $300 of work from me. So you will always come out ahead by fixing the one you have.
Time wise, the average customer has their headstock back in two weeks including transit time. Ordering a new one could take much longer, and a used one could take just as long waiting for the auction to end, the seller to ship, and transit time.
How long does it take?
Turnaround time is almost always 1 week. I stock enough parts to cover 10 to 20 repairs, a typical month, so I am not held up with parts delays.
I receive your headstock, typically tear it down and inspect it the following business day and email you my report. After you have paid the balance, I’ll repair it and ship it out the following shipping day. Paying via credit cards is the fastest way. I can bill you thru PayPal or my credit card processor Square and you can pay securely thru their web site. (Sometimes I prefer payment by check and when that is the case I offer a $25 discount on repair if paid in full within a week of invoice.)
What does it cost?
Labor plus the cost of parts and return shipping to you.
My base labor rate is $250. Add $50-75 if I need to open up the motor for bearing work or other serious problem.
I charge parts at their cost to me, not doubled. When appropriate, I supply good used parts at half the cost of new. Sometimes this is required because some parts are no longer made. Bearings, belts, electric cords and switches are always new.
Return shipping is based on distance and weight. It varies from $35 close to Virginia, to $65 to the West Coast.
The average repair is $350 to $400 plus the return shipping. This is very inexpensive divided out over the years of service the machine will provide.
Can I buy parts from you?
Yes, I do sell many commonly needed parts but others I typically don’t sell from my inventory. I typically stock enough for 20 to 30 typical repairs and if I sell from my inventory I run the risk of being low on parts when I need them. Some parts I have to get from SS and they are plagued with backorder problems so I especially am averse to selling those pieces. You should be able to get what you need from either your local bearing supplier, SS, some home centers or even new or used on ebay.
How does your service compare with factory service?
It costs about half as much to have me service your headstock compared with the factory. My typical turnaround time is 1 week where they quote 6 to 8 weeks turnaround.
My base labor rate is $250. They charge much more an hour due to overhead and unionized labor in Ohio. Naturally, I have much lower overhead which keeps the cost way down.
I charge you the parts at their cost to me and I only replace what is needed. For instance, when drive sleeve bearings need replacing (they always do) I charge $40 for the bearings. They will sell you a whole new drive sleeve ($100 or so). When a quill bearing needs replacing, I charge just for the bearing ($20 or $40). They will sell you a whole new quill ($120 or so). If your motor bearings are bad, it will cost $80 from me ($50 labor, $30 for bearings) where they will sell you a whole new motor ($400 or so).
When appropriate, I supply good used parts at half the cost of the new part. Sometimes this is required because some parts are no longer made. Most parts are new, however, and bearings, belts always are new.
Generally the bearings I install are better than the ones I take out of machines. They use bearings from Taiwan, Korea, even Slovenia. I try to use only US made bearings.
I provide a 90 day parts and labor guarantee for the work I do and the parts I replace. I haven’t heard what warrantee they have. I’ve only had 6 out of over 1,000 come back with a followup problem so I’ve got a great track record there as well.
I’ve now done over 1,500 Mark V headstocks so I’ve encountered all possible problems and situations. I encounter factory assembly errors often. I’ve had customers send their headstocks to me after a factory service, too!

The words Shopsmith and Mark V are trademarks of the company Shopsmith, Inc. I am not endorsed by nor affiliated with them in any way. I never worked for them nor was trained by them. I work independently and I learned my techniques independently through persistence, blood, sweat and tears. Like a step-child. They don’t even give me a discount on parts I order from them. Woe is me. But I wish them the best and want you to order parts, supplies and tools from them so they will be around a long time, or at least until I retire.
