Chalupy Acres: September 2014

http://chalupyacres.blogspot.com/2014_09_01_archive.html

Sunday, September 7, 2014. The Death Star, er, turnip. My life is somewhat unsettled right now. I will go into this later, after it settles. Meanwhile, it is fall in Alaska. Time to harvest the garden. Much to my surprise I grew the Death Star. This is the largest turnip I have ever grown. I did nothing. Like Topsy, she just growed. Outside temperature 10C, inside 19C, zucchini wonderful, tomatoes great. Ccn't believe the difference. Outside garden over. Greenhouse still going strong. App...Tiny Farm Blo...

Chalupy Acres: March 2015

http://chalupyacres.blogspot.com/2015_03_01_archive.html

Monday, March 30, 2015. Ividing head saga, part 3. But wait. The gear will not clear the shaft. So we have to mill out a 4mm pocket for the shaft. In steel and with a tiny mill ( Cecil. This is an ordeal - the biggest end mill is 3 mm and the pocket is maybe 30 mm. wide at the bottom. But the shape does not matter in the least, and there is less milling if you make it approximately circular. So there it is cut out. Now we have to attach it to the angle iron.

Chalupy Acres: Dividing head, part 2

http://chalupyacres.blogspot.com/2015/03/dividing-head-part-2.html

Monday, March 23, 2015. Dividing head, part 2. In the last post we saw the dividing head in its proto form. As near as I could reconstruct it, that is. But it is very flimsy, even though I intend to use it to cut clock wheels (gears) in plastic. So it is time for an upgrade to stiffer stuff. The first step was to substitute the flimsy plastic for something a little more solid, like angle iron. This was quite successful. I had to take off a full millimeter to get it flat.

Chalupy Acres: A table interlude

http://chalupyacres.blogspot.com/2015/04/a-table-interlude.html

Tuesday, April 7, 2015. This was an ordeal. The wood is gnarly. Well, at $2.67 for a 2x4 you can't expect much. I tapered the legs on the bandsaw, then planed them. Even so I used every plane in my arsenal. Now, for interest, I decided to arch the crosspieces. I rigged some trammel points. The arc I wanted turned out to be a meter ten! These are the pieces I cut out on the bandsaw, freehand. They still need some manual work, so I broke out the spokeshaves. I am not proud of the saddle joints, but I am no...

Chalupy Acres: Dividing head coninued

http://chalupyacres.blogspot.com/2015/04/dividing-head-coninued.html

Wednesday, April 22, 2015. It is unprecedented for me to post twice in an evening, but the Computer table needed a finale. So I finale-d it. So we are back to the dividing head. The critical part of this is getting the angles right, so that the gears will mesh. My original idea was to make the support post vertical. Then I had to measure the angle at which the shaft hole would be drilled. This was very difficult. The thing is very small and really there are no reference surfaces. The sector arms must be ...

Chalupy Acres: April 2014

Tuesday, April 8, 2014. Napoleon returned shortly after I did the post on him. He decided that the spot right beside my bedroom was the ideal spot for his moosely nap. He parked himself right next to my bedroom window. Fortunately I walked in time to get a picture. He was literally a meter away. Quite unperturbed by the pesky humans. Unfortunately the camera recorded the screen on the window, hence the weird effect. Subscribe to: Posts (Atom). Daesh invaded Prague's Old Town Square. My last blog post here.

Chalupy Acres: Dividing head contiued

http://chalupyacres.blogspot.com/2015/05/dividing-head-contiued.html

Sunday, May 17, 2015. The last post (sorry for the delay) showed the head mounted on the mill. This immediately showed a number of faults in the construction. One obvious one is that the slots in the head weren't long enough for the bigger gears in this clock. So take the head apart, and back to the mill. Make those slots longer. First to port. And then to starboard. Another view from the business end of the device, my Proxxon spindle knock-off. The spindle (b) rotate. The head the proper amount, (c) lock.

Chalupy Acres: August 2014

http://chalupyacres.blogspot.com/2014_08_01_archive.html

Thursday, August 28, 2014. Life is a grind. Now you might say "you have a lathe, dummy! Just turn the shank down! Alas, the end mill is carbide. If I tried to cut it with even a carbide tool, I would ruin the shank, certainly the tool, and maybe even the lathe. Not an option! The only way to do this with my equipment is with a toolpost grinder. Cut it off. Then I milled the ends square. Friday, August 8, 2014. Handy Bandy's vise, a long trip. Alas, this does not work. The bandsaw blade pulls left to ...

Chalupy Acres: April 2015

http://chalupyacres.blogspot.com/2015_04_01_archive.html

Wednesday, April 29, 2015. The romantic tale: mill meets dividing head. In this episode, we put the dividing head together. Some fancy milling was involved getting the worm shaft support to match with the tilted arm, but it got done. I spring-loaded the sector arms and they work fine. There is a collar that is pressed on to the crank arm, held down with a setscrew. Meet Ms. Head. Now the question is, does it fit? Is this true love? Wednesday, April 22, 2015. I resorted to my surface plate - the flattest ...
