A spindle steady is used to steady a long spindle while turning. The smaller the diameter and the longer the spindle is the more likely it is to vibrate and ‘whip’ back and forth, making it pretty much impossible to turn. The spindle steady, using clamping pressure with a series of wheels, tames this erratic motion allowing you to turn your piece as normal. Basically it minimizes the distance of support on your workpiece.
Making your own steady rest is rather straight forward and easily finished in a day, though an afternoon and a few hours the following morning is preferred since this will give time for the glued pieces to dry.
Here’s how we built ours:
We started with two pieces of 3/4″ MDF cut to 16″ square. The size in your case may differ, depending on the swing-over bed capacity of your lathe.
Next, we found the center of each of these pieces.
Then we made two concentric circles, one at the maximum diameter and the second one 2″ smaller. We didn’t have a traditional compass large enough so we just made a simple beam compass that consisted of a thin strip of wood, a tack and two small holes for trammel points that a pencil point fit through, which you can see here:
Next we cut a 3/4″ strip off one of the sides of each of the squares. This side will become the bottom and removing this strip will allow for the 3/4″ base that will be put on later.
Then, using an appropriate size circle (a large washer) we traced in a line that blended the outer circle into the bottom.
Next, using a jigsaw we cut out each of the rings. When doing this we started the jigsaw with a hole large enough for the jigsaw blade as near to the ring as we could since we would be using one of the centers for the base.
Once this was done we glued the pieces together and clamped it well:
While this was drying we cut 3 pieces of hardwood at 3/4″ X 1 1/2″ X 10″ for the wheel adjustment arms.
To make the slot in the arms we used a 1/4″ spiral bit in the router and set up two stop blocks on the router table fence to only allow the wood to travel the distances for the slot, which was 2″ from one end and 1″ from the other.
Then we rounded both ends on the bandsaw:
Then, on the end of each of the slider arms where we left the 2″ of unslotted wood, we drilled a hole and then bolted on a rubber wheel that we took off an old pair of roller blades.
Next, we cut a 6″ X 10″ piece from one of the ring centers for the base and rounded the corners and sanded off the sharp edges.
Once the ring was dried we sanded it a bit with an oscillating spindle sander, truing up the two pieces.
Once this was done, and the sharp edges rounded a bit, we marked where we wanted the sliding arms to go. We determined the positions for these by laying the ring on my workbench and then placed the remaining center piece back in the center of the ring. This gave me a center point again. Then we arranged the sliding arms so that the wheels would meet in the center and then traced the width of the arm on the ring.
We wanted very little movement between the arm and the ring, just enough to allow them to slide, so we cut tight to the drawn line. We also cut to about a 3/8″ depth. We cleared away the waste with a bench chisel.
We drilled the holes for the bolts that would hold the arms and added the base with a couple of screws and some glue.
Next, we made the pinch bracket out of a couple of pieces of scrap hardwood. The pinch bracket is what holds the steady rest on to the lathe bed so this had to be sized for the distance between the ways and to allow clamping pressure when the base bolts are tightened.
Then it was just a matter of drilling a couple of holes in the base, matching them up with holes in the pinch bracket and adding the hardware.
Installing the sliding arms on the spindle steady completed the project which gave me 12″ maximum diameter:
As you can see this is quite an easy project and one that can be pretty inexpensive. We were fortunate enough to have everything we needed except for a few wingnuts. Probably the hardest thing to get would be the wheels but these can be picked up at yard sales and flea markets pretty cheap.
Here’s a list of what we used:
2 pieces of 3/4″ X 16″ square MDF (for the rings and base)
3 pieces of 3/4″ X 1 1/2″ X 10″ hardwood (for the slider arms)
2 pieces of approx. 3/8″ X 3″ X 6″ hardwood for (the pinch bracket)
3 roller blade wheels
5 – 2 1/4″ X 1/4″ bolts (for slider arms and base assembly)
5 – 1/4″ wingnuts
5 – 1/4″ lock washers
3 – 2″ X 1/4″ bolts (for the wheel assembly)
3 – 1/4″ nuts (for the wheel assembly)
3 – 1/4″ washers (for between wheels and arm)
If we were to build another one we would place the sliding arms at an equal distance around the ring. In this version we wanted one that would be located behind my turning, giving support when force was applied with a tool. Doing so would have placed one of the arms in an awkward place (so we thought) and we would have been prone to bumping into it so we placed it straight at the top. The problem with this configuration is that when working on a very small spindle the top and back wheels can touch, causing them to reverse on each other. Now, although this is easily remedied by simply reversing either the top or back sliding arms it made for an unnecessary solution since we later found that had we placed the top one at an equal distance around the ring it would not have been in our way after all. 🙂
Another change we would make is to design one that had an opening in the ring that will allow you to install the steady rest without having to remove the tailstock. This would be a lot more convenient.
Update – 04/08/12: We see that Lee Valley is now stocking Polyurethane Wheels, originally used for kick scooters, that would work very well for this project if you don’t have access to roller blade wheels. At only a couple of bucks each they look to be a great deal. Find out more here.
