The boiler kit comes with just about everything you need to build a great vertical boiler. You'll find the material nessesary to make the riveting tools except the anvil itself. Lets start with making the tools for installing the tubes as well as the rivets. Then we will be set to begin on the boiler itself. Ther are four tools needed for setting the rivets. The three on the right are for the outside of the heads, while the anvil and another punch is for the inside to hold the rivet in place while swagging and peening the head over. PM gives an excellent discription of how to make the tools, harden them and also how to properly set them. Also shown is how to make the flaring and rounding over tool for installing the firetubes. Again they give a great discription of how to do this.
To the left is the anvil tool that is used to hold the rivets while you set them in place by peening them. Its really a simple job taking only about a minute for each one.
Notice on the two tools on the right side have bands on them. The middle one with the longer band is the deeper of the two which are hard to tell apart. The one on the right has a shallow band indicating the hole in the end is shorter. It makes it a lot easier when installing them.
The picture on the left shows how I added three pieces of 1/4" square to my anvil to help hold it in my vise. You can see where I tacked two on the top and there is also one on the bottom. My vise was allowing it to slip down and this prevented it from moving.
Shown is the flaring tool used for the boiler tubes, The one on the left is used for rounding over the tubes while the right one is used to start the flare so the left one can bend them down flat.
The thirteen boiler tubes were cut to length with my small cutoff tool. Its great for small pieces of copper and brass. I wouldn't want to cut much larger than these tools. I bought it from Harbor Freight for 20 dollars on sale. A good deal for the money!
The pieces were then deburred and the ends cleaned for soldering
While making the tools I also made four wooden blocks to use as spacers between the top and bottom sheets. This enables you to use a bolt provided to flare out the tubes
Here we have seven tubes installed with six to go. Use a drop of oil on the end of the flaring tool as it makes it much easier and does a better job. You can clean the oil off before soldering. I thoght this might be a problem but after using a good degreser and some alchol it soldered just fine.
I'm getting ready to flare the tube first and then round over the end using the other side of the tool. It only taks a few minutes to install each tube. The whole job took less than an hour.
