A Craftsman's Combination Foot-Lathe 



An inexpensive combination scroll-saw and wood-lathe 

 By C. H. Patterson 



SIMPLICITY and economy have been 

 kept in view in designing this combina- 

 tion lathe. It will swing 6 in. above 

 the bed and 4 Yi in. above the tool-rest sup- 

 port, and it is about 18 in. between centers. 

 The swing can be made greater by increas- 

 ing the height of the head and tail stock- 

 standards, and the 

 length of the bed 

 can be increased to 

 4 ft., if a third bend 

 is made in the crank 

 as shown in the cen- 

 ter line drawing. 

 In this case, it will 

 be necessary to use 

 a crank of larger di- 

 ameter, say, i^ in. 

 The bed of the lathe 

 is made of two hard- 

 wood timbers 36 in. 

 long, 4 in. wide and 

 2 in. thick, sepa- 

 rated, as shown in 

 the end elevation, 

 by I by 3-in. pieces, 

 to which they are 

 bolted. The left 

 piece forms a part 

 of the outer stand- 

 ard, as shown in the 

 detail drawing of 

 that standard. The 

 legs are of stock 3 

 in. wide and 2 in. 

 thick. A triangular 

 piece is sawed from an upper corner of each 

 leg. These pieces are nailed to the outer 

 surface of the legs, care being taken to place 

 them so that they will not be in the way of 

 the holes bored for the bolts. These holes 

 are then bored and the legs bolted to the i 

 by 3-in pieces mentioned. It will be seen 

 that the triangular blocks provide parallel 

 surfaces for the heads and nuts of the bolts 

 that pass through the legs. 



The crank is of i-in. iron, bent as 

 indicated in the center drawing. This will 

 be a job for the blacksmith and machinist, 

 but the cost of the completed crank should 

 be small. For a distance of i in. inward 

 from the ends of the crank, it is turned to 



The lathe as it is used 

 tachments may be appUed 



a diameter of ^ in., to provide bearing 

 surfaces. Pieces of J^ by 3-in. stock 

 are screwed across the outer sides of the 

 legs. To the inner surface of these pieces 

 are nailed other pieces of i-in. stock, in 

 which holes should be bored to receive 

 the bearing-ends of the crank. 



A strip of I by 

 4-in. material is 

 nailed across the 

 back of the legs and 

 to it are screwed 

 the hinges upon 

 which the pedals 

 swing. The pitmen 

 may be cut from a 

 I-in. board. Holes 

 are bored in them 

 to receive the 

 cranks. A central 

 slot is made with a 

 saw-cut in the ends 

 of the pitmen for 

 about half their 

 length, and the 

 parts are pried open 

 and slipped on the 

 cranks. Some 

 pieces, i by 3 by 4 

 in. are nailed to the 

 lower side of the 

 pedals and nails are 

 passed through 

 them and through 

 the pitmen. Half 

 round strips are 

 nailed across the pedals near their free ends 

 for the feet to rest upon. 



The drive wheel is built up of three 

 series of segments cut from i-in. board, 

 preferably of hardwood. The single spoke 

 in this wheel is also built up of three pieces. 

 The central piece of the three must extend 

 well into the wheel-segments. These 

 segments can be sawed with a band-saw. 

 The hole in the spoke that receives the 

 crank-shaft should be bored true in a 

 boring machine. A smaller hole is bored 

 through the spoke to receive a pin, for 

 pinning the wheel to the shaft. After the 

 wheel is mounted, a board may be clamped 

 across the legs, close to the wheel, for a 



for turning wood. At-
