« Part 4: Finally getting it together, Bed to Headstock Part 5 of Scrap Iron Wood |Lathe series Part 6: Attaching the motor and making accessories. »

So far the lathe was built without any need use a tape measure etc. just a stick would have been enough, Today we need to use fine measurements down to .001 inch. micrometer needed, but one could just machine to fit. The first thing is to make two collars with a 1 5/8 inch inside diameter. I think I used 2 inch stock from making the spindle insert. Drill and bore.

I almost forgot to drill a hole to make a key way, since I do not have a broach. The center of the hole you drill is the outside diameter of the hole. This picture is poor but is the only one I have.

After it is bored to the size needed, only 1/2 the hole is now seen, one can square it up abit with a file. This is the only way I have figured out how to make a key slot inside a hole.

Now one just has to mill key slots in the spindle in the appropriate place.

The next thing to do is make the index plate. I had a larger one so I need to cut it down to fit inside the headstock.

I neeeded a series of closely spaced hole in the plate, Just made a jig out of wood with the 10 degree angle. Each time a hole was drilled the plate was rotated and the pin put back in.

The plate was then drilled and bored out to fit a shoulder I lathed on one end of the collar, then welded together, I then drilled and tapped two holes for set screws, If I had remember it would been easier to do befor it was welded together.

The same operation was done on the collar for the pulleys, I made a longer collar and machined a shoulder on both ends. Set screws in the center of the collar. The weld on pulleys I was able to buy had an inside diameter of 1 1/2. They had to be bored out to fit on the shoulder and then welded on.

Thought I was about done but then figured out I need some thing to stop the spindle from being pushed out when pressure was applied by the tailstock. I thought a snap ring would work, but they did not have the size I needed in a local store. So I came up with this idea. Machine a ring, cut it in half, machine a collar with on end machined out to the outside diameter of the ring and in at least its thickness. I installed it ahead of the outside bearing. Works excellant.

Assembled and in place.

The next thing I did to complete this section was to drill a hole in the center of two bars. using a pin to line them oup with the indexing plate they where welded place. The main thing this is used for is to lock the spindle to remove the spur and chucks.

complete with pulleys also

The last thing to do was to make a lid and pulley guard, Little blocks of metal where welded on for hinges.

That was allot of fiddle work to complete this section. I did all this work while I was building the basic lathe, early in the morning when it was still dark and cold miserable days. That way parts where read when needed.
About blossumed out now, just have to make some accessories now and attach the motor, will do that in the next post.
Thanks for looking, hope you where entertained by this blog. Comments appreciated
