1.Plywood with a thickness of 18 mm was used for the plate to which the bearing guide attached.The part which is a little insufficient in wide was joined with biscuit.

2.First, Marking the donut cutout position and the cut of groove section. And fix the guide of the trimmer with wood screw.

3.Cut the groove with a width of 20 mm depth of 6.1 mm with a trimmer.

4.Cut it in a donut shape with a fret saw.

5.Grind the outer circumference with homemade disc sander.

6.Grind the inner circumference with homemade spindle sander.

7.In the center part of the fold in which the hinge is attached, a round groove is put in to eliminate interference with the hinge.

8.I tried installing a hinge, but I thought that folding had worry of strength and vibration.Therefore I decided to make it in one piece this time. (The drawing has not been modified)

9.Drilling to attach the donut plate to the fixing bracket.

10.This is leg holding a single pipe of a lathe. It's a 40 mm square piece of japanese ash.

11.Groove processing to insert the bracket to fix the donut plate. Width 18 mm, depth 15 mm. The bit diameter is 15 mm.

12.Cut it adjusting with fence microtremor system.

13.Cutting of the 15-degree inclined portion on both sides of the bracket was made with the cutting jig of the segmental bowl member.

14.The upper part of the stand sandwiching the single pipe of the lathe. Drilling 3.8 mm.

15.Drlling 9mm for insert nut.

16.Screw the M6 insert nut with a 6 mm Allen wrench.

17.Screwing was completed.

18.Assemble legs in a gate shape. Use screws and adhesive together. Also, bond the triangle to the corner for reinforced.

19.Make the insert rod for pipe protection from the 8mm brass rod. It's into the bolt tip of the clamp lever. First cut to a predetermined length.

20.Turn the end of the rod to 6mm in diameter.

21.Make the tip on the 8mm side the same as R of single pipe by file.

22.The completed insert rod.

23.Insert the rod into the insert nut for the clamp lever. In the center of the nut is a part with a diameter of 6mm.

24.The tip of the insert rod to fix the single pipe.

25.The slide bar for mounting the resin bearings is 20 �– 6 t aluminum. Grind the bearing mounting side to R10.

26.Chamfering on the opposite side.

27.Drilling 5mm for M6 tap.

28.Tap M6.

29.Threaded hole in the plate that holds the slide bar. Drilling 3.8mm.

30.Drilling 5mm for M6 tap.

31.Tap M6.

32.Assemble the slide part and check whether it moves smoothly.

33.Assemble the whole bearing part and check the center.

34.Temporarily install the stabilizer on the lathe. Find the position where the center of the bearing section and the lathe center meet. And marking its position.

35.Preparation for bonding of single pipe fixing base and donut part.

36.Bonding complete.

37.I tried trial running of the stabilizer, I think that it seems that you can work comfortably without vibration.

38.Scale o‚† aluminum bar. Fi‚’st, Hold the round bar of a diameter of 20 mm with the stabilizer while holding it with the tail stock.

39.Marking the position while holding firmly.

40.Based on the position of 20 mm, mark the position in 20 mm steps and write in the dimensions with the magic pen.

41.This scale will be a guide for centering.
