Contemporary Nativity Scene

Difficulty Level (Easy, Medium, Hard, Insane):
Easy

Process:
I came across a picture online of an Ultra Modern Nativity Scene and was quite intrigued with the set. It was designed by Sebastian Bergne but unfortunately, he only made 250 sets and paying $140 (CAD) for a bunch of painted blocks is just a little bit too much for my budget.

Regardless, the longer I looked at the pictures, the more I started to like it and decided I was going to make a set for my wife. The design is so simple and the only real challenge in reverse engineering was to come up with the proper dimensions, so here they are (H x W x D):

Joseph, wise men, Shepherds: 4" x 1" x 3/4"
Mary: 2-1/2" x 2" x 3/4"
Jesus: 1-1/2" x 2" x 3/4"
Angel: 4" x 3/8" x 3/4"
Stable frame outside: 5-3/8" x 9-7/8" x 1"
Stable frame inside: 4-1/8" x 8-1/2" x 3/4"
Stable back wall: 4-1/8" x 8-1/2" x 1/4"

The material I used for the blocks was solid white oak, the back wall of the stable was oak laminated particle board and the frame of the stable was made with solid pine.

After I cut the strips oversize, I put them through my planer and cut them to length on the chop saw. Then came the fairly time-consuming process of sanding the pieces on the belt sander.

To paint the pieces, I drilled a small hole into the bottom of each of the blocks and hammered a nail into it, then I took a 3 foot piece of 2x2 and drilled a bunch of holes (the same size as the heads of the nails) at 2" intervals. That way, I could paint the underside of the block, then stick the nail into the hole of the 2x2 and paint the sides without having to touch the pieces. Also, I was able to do it all in one coat and it could dry all around.

After the pieces were dry I put a thin clear coat over it all and let it dry over night. All that was left to do in the morning was to assemble it and present it to my wife.

Fixing Our Broken Christmas Tree

Difficulty Level (Easy, Medium, Hard, Insane):
Easy

Process:
So today was the day we were going to set up the Christmas tree for this year. Unfortunately, after so many times hauling it up and down the stairs each year, the top part of the Christmas tree got bent one too many times and broke off 1.500" into the top most piece.

After analyzing the situation, I realized that I couldn't just weld the pipe together because there was too much greenery, string and hot glue from when they originally made the tree so I had to look for an alternative.

After some thought I figured it would be a perfect project for my lathe. I had been sick all week and hadn't been out in the shop at all and I still wasn't 100% but my wife and kids were eagerly waiting inside so I cut off the broken piece of steel pipe out of the center of the tree and cleaned it up, then hauled out a piece of 5/8" cold rolled steel, turned a 1.500" length of the one side down to 0.450" and a 1.500" length of the other side down to just a little under 5/8". Lastly, I drilled a 1.500" deep hole at 0.450" on the thicker end, hammered this newly finished piece of metal into the Christmas tree pipe and voila, the tree was fixed.

After I put the tree back together I realized that two of the rubber feet had fallen off the tree stand which we were going to fix for the last few years but never got around to, so I figured I might as well take another 20 minutes and make 4 new tree stand feet out of teflon. That part was pretty easy: Clean up the pipe, turn 0.500" of one side down to 0.450" and 0.250" of the other side to about 0.750". All I then had to do is hammer the 4 little feet into the tree stand and now I can slide the tree around on my hard wood floor without scratching it up.

Making a Bag Pipe Drone Stock

Difficulty Level (Easy, Medium, Hard, Insane):
Easy

Process:
A gentleman from Moncton contacted me if I could make him some bag pipe drone stocks on my lathe and after looking at a sample he brought I took some measurements and started replicating. The steps were as follows:

1. Cut 6" pieces out of 2" solid Acetal
2. Chuck and indicate, then center drill the stock
3. Turn the outside down about 0.015" for a nice surface finish
4. Drill 4.500" deep, 1" wide
5. Bore 4.500" deep, 1.580" wide
6. Part off at 4.500"
7. Face the remaining 1.500" long piece
8. Turn it down about 0.015" for a nice surface finish
9. Flip it around and face the other side
10. Turn down 0.900" to a diameter of 1.560"
11. Thread at 32 TPI for the hemp to have something to grab on to
12. Flip it around and use a profile cutter to cut the curvature
13. Drill three 5/8" diameter holes spaced equally into the face
