Like the travelling steady,  some workpieces will be impossible to machine without a fixed steady. However, in most workshops, the fixed steady will find much more use so is an essential item.

 

Photos 1,2 and 3 show an item that would be all but impossible to machine without one, it is a body for a milling cutter chuck. With the material held by the chuck and supported by the tailstock four surfaces are machined, left to right, the chuck’s taper, a surface for the steady to support, the thread for the chucks closing nut and a parallel portion for locating the closing nut, Photo 1.

 

Photo 2 shows the fixed steady being set whilst the part is still supported by the tailstock, the tailstock then being removed and the bore for the chucks collets made, Photo 3. This ensuring that all the surfaces are concentric, including the bore.

 

Whilst the tasks in Photos 4, 5 and 6 could be carried out by other means there are advantages in using a fixed steady.If needing to support a workpiece between centres, centre drilling its ends accurately is not easy. Using a fixed steady as in Photo 4 is easy and  produces a very accurate result.

 

Photos 5 and 6 are material saving setups. In Photo 5 large washers are being made. Had a short length of  material been held in the chuck, then after making a few a short stub would be left in the chuck which may never find a use. Particularly wasteful if a large  number of washers were being made.

 

The photograph  also shows that parting off is possible, as easy, if not easier, than parting off near to the chuck.  

 

Photo 6 is a similar situation where a number of spacers are being made.

 

Not available with all steadies but Photo 7 shows that in this case it can be opened up enabling the part to be removed and replaced without the need for resetting the steady, a worthwhile facility.
