Re: WANTED: Boiler for 16' Steam Launch

The link brings up a page with more than one boat, none of which has an engine meeting the description. Does it have a name?

Most boilers are pretty much indefinitely rebuildable. Have you given any thought to that option?

Re: Boiler Lagging

I don't know if there is any insulation under your lagging but this might be an opportunity to add some. As well as refinish your lagging pieces. As Ron says, those el cheapo 1" wide ratchet straps work great to pull everything together when it's time to reassemble.

Re: Stuart no 6

The one I fixed and the one I was told about both broke right where the threads started. Smaller effective diameter and some sharp edges resulting in stress risers. I like your extended rod not that it would help the breakage at the threads so much but that it should reduce friction due to poor rod ...

Re: Stuart no 6

The one I most recently dealt with had a broken 5/16" H.P. valve rod. To think, I thought I was making a big upgrade by going to 3/8"!

Re: Electrically fired Boilers?

This happened not that long ago in the Seattle area. No injuries or fatalities but half of the building was spread all over the neighborhood. The history if this event was that the temperature/pressure valve had leaked at one time and some inspired soul had replaced it with a pipe plug. Years later ...

Re: Stuart no 6

Give some consideration to fitting a larger diameter H.P. valve rod. There has been more than one failure.

Re: Electrically fired Boilers?

I wouldn't worry too much about using propane in a decent sized room. There is a propane stove in my kitchen with four burners and an oven and at the holidays all are running full tilt. I do use the hood fan once in a while but mostly to get rid of the stink from my entertaining cooking blunders. My...

Re: Machinest Question

I prefer the first video. Not so hot on the head banger music. I've had production jobs where I had to tap hundreds of 5/16" holes in 1/4" 6061 aluminum. Used a two flute spiral point tap with no lube and I still have the tap. Used a hand held electric drill. Of course high strength aluminum is abou...

Re: Counter-clockwise Drill bits

In the past I've electric welded a large bolt to the offending fastener and then used in air or electric impact gun to remove it.

The thermal shock really loosens up the rust.

Re: Machinest Question

Just got back from a couple of weeks in the woods of northern Idaho and Montana in my van. Got chased home by intense heat and zillions of idiots with no masks, Sigh. In Fred's situation I use a tapping guide too. I don't bother threading it though. Just drill/ream it to a close fit on my tap. I've ...
