HOW I made a serviceable little woodturning lathe at an expenditure of $3 is shown in Fig. 1.

The lathe has proved to be powerful enough, nevertheless, to turn out any job within the scope of my home workshop.

CRACKS and holes are common blemishes in the average plastered wall. These do not always indicate that the plaster is old and worn, for even new work is likely to have ugly cracks at the corners if the house settles unevenly. A nail, picture hook, or the continual bumping of chairs, toys and other objects often cause unsightly holes.

To provide space for a deeper drip pan or a good sized bucket and also to reduce the amount of stooping the housekeeper has to do in using the refrigerator, we have made it a practice for many years to build a solid frame or pedestal from 8 to 10 in. high upon which to set our ice box.

FLOATING reamer holders of many designs are made for use on turret lathe work. For the most part they are only semi-floating because they are rigid in one direction. Consequently the benefit of the floating effect is not available. The design illustrated has a full floating joint, which overcomes many of the defects found in the semi-floating type.

Assuming that the cylinder is fairly true, that the piston fits reasonably well, and that the piston ring grooves are found to be square, then only an allowance for heat expansion need be considered.
