Building a Birdhouse


I've been wanting to build a birdhouse with Joshua for awhile but I've been waiting to get some inexpensive pine from Home Depot to do it. They sell 1x12x8 pine for less than $10. Even though it is full of knots, it's great wood for simple kids projects. It is soft and easy to work with and will take paint well.

I used the plans from the book "The Kids' Building Workshop". The plans used cedar shakes but the pine was an easy substitute - I did have to trim up the roof a bit to get it to fit properly.

To start with, we rough cut the 1x12 in half, then ripped the half to get 2-1x6x4s. When working with Joshua in the workshop, I've got a milk crate that he stands on to watch when I am working with the jointer, tablesaw or mitresaw. I place it in a safe location then he stands on it until I am done with the tool. For these tools, his job is to turn on and off the dust collector before/after the tool is turned on.

After the rough cutting we used the planer to plane down one of the 1x6s to 1/2" for the roof, the other to 3/4" for the remainder of the pieces. Joshua is allowed to help with the planer, he feeds to pieces in and I catch them at the other side. We usually open up the garage door and let the chips fly, then it's easy to scoop them up and dump them in a garbage can when we are done.

Joshua went back on the milkcrate as I used the jointer to clean up one edge before heading to the tablesaw to rip the pieces to width. Next the mitre saw to cut out the individual pieces.

Over to the drill press, Joshua drilled out the hole for the entrance, then the small hole to hold the entrance perch. You can see in the video below about 1:40 what happens when you don't keep a good hold on the drill press handle - I think I need to get him a bit higher stool for the drill press.



Lastly I clamped the pieces together and started the nails, then Joshua finished them off. We screwed the bottom in so it is removable and now some lucky bird will soon have a nice new home to live in. We'll give the outside a coat or two of paint or stain before we hang this up.

This was the first birdhouse I've ever built - I'm pretty sure I'll be building plenty more. Though maybe we'll do a bat house next...

Playhouse Rocketship - Part 6

A few days ago I gave up on the idea of getting this done for Joshua's Birthday. I was planning to take a day of this week to finish it up, but I had to take the day off to watch him as school ended one day earlier for him than Rosemary. I'll have to start earlier next year...

I glued up the circular ribs for the rocketship. The outer panels will be glued to these ribs. They are made up in four parts and each half is glued together, than secured to the other half with 1 1/4" wood screws. If I had the inclination, bolts would have been better, but assembly shouldn't have to happen very often - just to bring it into the house.

I originally planed to use the router and a straight cutting bit to trim down the ribs so that the circle pieces would all be on the same plane but gave up on that idea after trying it on some scrap - maybe next time. I used the larger circle as a template, stacked the pieces then glued and screwed two joints and screwed the other two to get a full circle. After doing this twice I had my two rib circles.


The circular ribs will be supported by some vertical ribs that will be attached to the bottom circles. I cut up three vertical ribs, one 3/4" longer than the other two. The longer piece was secured to the bottom circle, then I cut a recess in the top circle of plywood to slide it into place. Next the other two vertical ribs were glued and screwed to the top circle. My pin nailer made all of this much easier - pin the pieces in place then drill the countersink and screw them down. In the photo below you can see the cutout in the bottom plywood for the closes vertical rib.


Next I stacked up the circular ribs, adding another layer of vertical ones in between. The idea is that each circular rib half is connected to one of the circles on the bottom. The sides of the rocket will be secured to one half of the circular rib and the adjoining circle on the bottom. The circular ribs can be unscrewed and the rocket can be divided into two for transport. Since it is slightly larger than 40" it won't fit through a doorway unless this is done.



One coat of black paint on the rocket engines - looks good to me!

Playhouse Rocketship - Part 5

Early in the evening, Lauren took a quick trip out to the workshop with me and I glued up the rocket motor blanks while she played with some scrap wood and sawdust. Too bad the camera batteries died before I could get her picture :(



Later that night I finished cutting out all the quarters that will form the ribs of the rocket. The process went like this :
  • trace master template onto plywood
  • rough cut blank from plywood with jigsaw or bandsaw
  • use pin nailer to attach two blanks, then pin the master template onto the top blank
  • use bandsaw to get with 1/8-1/16 of the template
  • over to the router to use a straight cutting bit with a bearing guide to cut right to the template
  • disassemble and remove pins with pliers
Took about 10 minutes per set of two blanks once all the pieces were rough cut.



Lastly I put a coat of primer onto the rocket motors using a disposable foam brush. I'm tired of cleaning brushes.

Playhouse Rocketship - Part 4

A few things done but it looks like time is running low on this project. Hopefully I'll scrape together some time to get things done this weekend.

I had some other painting to do, so all I got done were two more 'quarters' for the ribs of the rocket ship. I stacked two up with the template and ran both through the bandsaw and router at the same time - this will save me a bit of time as I've got 12 total to do and only 3 done!


Lastly I finished up the 6" circles that will be the top of the rocket engines. Here's what the finished rocket engine will look like. Still debating whether or not they should be painted - Rosemary votes no.


It was a good time in the workshop as nothing bit me :)

Playhouse Rocketship - Part 3

Today I finished cutting up the last two blanks for the rocket motor circles. I've still got one more set of circles to make up (6") but I haven't glued up those blanks yet. I'll get that done today.

After finishing the cutting I moved over to my oscillating spindle sander and smoothed out all of the circles. The Ridgid OSS is a great tool and the dust collection is fine for me. I used the belt attachment to round out the circles.



The circle jig I made up the other day for the band saw works reasonably well, but the flex in the blade means the circles are not perfect. The OSS got them close enough for my rocket motors. If I need perfect circles I think I'd use the router to cut them instead. For this project perfection is not needed - it's not rocket science, it's rocket woodworking!

After the OSS it was over to the router table and a 1/4" round over bit with a guide bearing to smooth out the edges. In retrospect I probably have only done one side of the motor, but I don't think Joshua will complain.



The next thing to work on were the plywood bottoms for the rocket. These 40" diameter circles were a snap to cut on the circle jig. I first used the tablesaw to carve up two 41x41 squares, then over to the bandsaw to cut the circle out. Lastly I lined the circles up with their center holes and cleaned up the edges with the bandsaw. These two will form the base of the rocketship playouse, resting on top of the rocket motors.

Next I need 3 hollow circles to support the shell of the rocket. Two for the main body and one for the bottom of the nose cone. Rather than wasting 1.5 sheets of plywood I decided to cut quarter circles out of one sheet and glue them up to form the circles. They should be plenty strong enough for this playouse.

First I made up a template for the quarters with some scrap 3/8" plywood. I used the bandsaw circle jig to cut the quarter circle template at the same diameter as the bottoms (40"). I cut the radius by 3" to cut the inner part of the template, making the template 3" thick. The template ended up being 32" in width as I left about 3" on each side for an overlap.



I used that template to mark out blanks on a 33"x8' sheet of plywood then cut them out with a jig saw. After tacking the template to the blank with a pin nailer I cut down to within 1/8" of the line on the bandsaw.

Finally, over to the router table with a guide bit to trim the blank to the same size as the template. I was only able to finish one piece, but I've got the process down so the others should go quickly.

The last thing I did was glue up blanks for the 6" circles for the rocket motors.
Caution : OSS' bites just like the bandsaw :
