Stitching Horse Drawings

1. Reduce all pieces to finished dimensions.

2. Draw a centerline lengthwise of the seat piece and also lines across the stock 5*4" from each end, and at the intersection of lines swing arcs with a 5y4" radius.

3. With the compass set at 9 swing an arc at each side tangent to the arcs at each end.

4. Remove stock to line with a turning saw, keyhole saw, or by making saw kerfs to the line and removing the stock with the draw shave. The edge may be smoothed with a wood file.

5. The stock on the upper side of the seat where the worker's legs rest on the seat may be further removed with the draw shave and smoothed with the wood file. Fig. 23. Front vkw of stitching Horse.

6. To lay out the mortise for the post on the seat locate a point on the line across the front end of the seat Vi" from the centerline as shown in the detail drawing. Set the T bevel at Ys pitch using the figures 12 and 3 or 4 and 1 on the steel square and draw lines for the sides of the mortise. The end lines of the mortise are at right angles to the sides. The mortise extends thru the seat at the above angle and the T bevel may be used as a guide in boring out the stock.

7. Remove the stock for the mortise with bit, chisel and mallet. It may be noted in the detail drawing that the mortise is 1%" x 3*4".

8. Set the T bevel at 221/4" and 4%" on the steel square and lay out the cuts at both ends of the legs and left side brace. A shoulder is cut at the upper end of the legs 1" from the end so that the end will go into the holes which are bored in the lower side of the seat.

9. At a point 6" from the lower end of the left legs and on the inside lay out gains 1/4" deep and l1/^" wide across the stock to receive the ends of the left side brace. The stock may be removed wit h the saw and chisel, making the saw kerfs close together. Use the T bevel as set for the ends of the legs. This will place the top and bottom edge of the brace parallel to the floor when the horse is assembled.

10. Assemble the brace and left legs by the use of one 2y£" No. 12 flat head bright wrood screw at each joint. The holes for all flat head screws should be countersunk so as to place the screws sligl tly below the surface of the wood. In placing screws it is well to use two wood twist drills; one the diameter of the wire of the screw to bore a hole as deep as the screw up to the threid on the screw and another fa" smaller to bore the hole slightly deeper.

11. Locate points on the inside of all four legs on a centerline and 8" from the bottom end of the legs and bore holes deep for the ends of the end braces. The holes are bored at the same angle as is used for the ends of the legs. The ends of the braces are roui-ded so as to draw snugly into the holes.

12. Locate points on the two right legs ZVz" from the bottom onds and bore holes for the right side brace.

13. Fasten the braces to the legs by using one 1%" No. 9 flat head bright wood screw at each joint.

14. Lay the seat on the bench with the bottom side up. D^aw a centerline lengthwrise of the; stock and lines across the stock 5^4" from each end. Locate two points on each line across the stock 4" frcm the centerline. At these points bore holes 1" deep, using the T bevel set as for the ends of the legs for a guide.

15.- With a twist drill of the size of 2y2" No. 12 screws continue the holes thru the seat from the same side. Countersink the hole \ from the upper side of the seat.

16. Place the legs in position and with a twist drill fa" smaller than the above bore a hole into the top end of each leg for the screws.

17. Fasten the seat to the legs using one 2y2" No. 12 flat head screw at each joint.

18. By use of the T bevel as set for the mortise thru the seat lay out the lower end of the clamp and post and remove the stock with saws as shown in the detail drawing of clamp.

19. Lay out the mortise for the key thru the post at the dimensions shown in the detail drawing of the clamp. Remove the stock with bit» chisel and mallet.

20. To lay out the clearance space on the clamp and post, draw seven lines across the inside and both edges of each as shown in the detail drawing; the first %" from the end and the others 2" apart. Locate points on the lines across the edges as shown in the detail drawing and lay out the curves free hand. The stock may be removed by making saw kerfs close together across the stock and removing the wood with the chisel and draw shave. The surface may be smoothed with a wood file.

21. Draw lines across the upper ends of the post and clamp y±f from the inside edge and a line across the outside of each 2%" from the end.

Lay out a curve free hand for rounding the corners and remove the stock with the draw shave. The surface may be smoothed with the wood file.

22. Draw a line across the outside of the clamp, 10" from the lower end, and on this line make an opening for the strap thru both clamp and post, using the %" bit as shown in the detail drawing.

23. Bolt the clamp and post together with two 5/16" x 31/2// machine bolts placed as indicated in the detail drawing.

24. Place the two steel butts as shown in the detail drawing 4" from the lower end of the clamp.

25. Remove the hinges and saw the clamps in two below the center of the hinges; then replace the hinges. If it were sawed first and then the hinges placed in position the clamp would drop down the thickness of the saw kerf and not match at the top with the post.

26. Shape the key as shown in the detail drawing of the key.

27. On a line drawn parallel to the side of the mortise and 2%"

from the side of the seat and 6" from the front end of the seat, make a slot through the seat 5/16" wide and 1 y§" long for the strap to pass thru.

28. The coil spring is placed directly below the strap between the clamp and post. It may be held in place by bending about %" of one end of a wire at a right angle to the length of the spring and forcing this bent end into a hole in the post.

29. Cut a piece of galvanized iron or other heavy sheet metal 1" x 1*4" and bend to a right angle as shown in the detail drawing; place it in the strap opening in the post and fasten with two small flat head screws.

30. With the hack saw cut a piece of metal for the lock x l1/^" x 5". The notches are y2" deeP and shaped as indicated in the detail drawing. They are cut with the hack saw and the corners are rounded with an iron file. Centerpunch for holes for the screws as shown and drill 3/16" holes, using the drill press or breast drill. Fasten the clamp to the right front leg with four 1" No. 9 round head blued screws so that the lower end is from the bottom of the leg.

31. By use of the hack saw cut a piece of metal for the catch 1/4" x 114" x 21/2", heat to a cherry red heat and forge to the form shown in the detail drawing. If a forge is not available it may be filed or ground to the form and bent slightly with hammer and vise. Center-punch for three holes and drill fV" holes. Fasten to the top edge of the lever with three 1" No. 9 round head blued screws.

32. Cut a piece of metal with the hack saw x l1/^" x 5yo". Centerpunch for the holes and bore three 1/4" holes as indicated. Heat the metal to a cherry red heat and bent to a U form to the dimensions shown in the detail drawing.

33. Bore a 14" hole thru the left horizontal brace at a point 2" from the front end and fasten the U iron in place with a 14" x 2" machine bolt.

34. Bore a hole thru the left end of the lever and fasten into the U iron with a x 2" machine bolt.

35. File both ends of the 2heavy steel wire to a point; bend Vfc" of each end at a right angle. Drill holes and fasten to the lower edge of the lever so as to hold the strap at 7" from the lower end of the lever.

36. Fasten the buckle to the end of the strap; strip a leather loop on the strap; draw the strap around the lever thru the bent wire guide and again thru the leather loop and thru the buckle. Draw it up thru the slots in the seat, post and clamp and fasten to the outside of the clamp with three lining nails.

37. With the belt punch make holes in the strap 1" apart, and draw the strap up so that the lever works the clamp and locks it.

38. Wood deteriorates in value and strength as it constantly increases and decreases in moisture content. This may be largely prevented by covering with a coat of paint or shellac. It is suggested that the stitching horse be finished with two coats of shellac.
