Re: And Now for the Twin

Depends the type of alcohol. All of it that I use for electronic cleaning is flat out lethal to drink and methyl is even dangerous to breath. I know. I burn it in my Jawa race bike.

Re: Con-rods and length

I've seen machinery that was designed that way and always wondered if it would wear evenly along the guides. I guess that's just as much of a problem with a sliding contact. But wouldn't the guides that the ball bearing run on need lubrication anyway? Unconfined oil and grease is what I'm trying to ...

Re: Con-rods and length

I'll give that some thought. I've always liked Watts linkages because there were just pivots. No siding areas that drip oil all over the place. The one such engine I have is just a Stuart walking beam engine and the loads are very light. On my launch engine the needle bearings for the pivots would h...

Re: Con-rods and length

I'm so glad to see someone else using anti friction bearings. Even my Strath single still has a plain brass big end though the mains are single row balls. If I ever have any trouble with the big end I will re-engineer the crank for a sealed ball bearing. That would leave me with only one oil cup for...

Re: DetroiTug's Tug is going together

I've been the route with various portable fridge systems. The best two are absorption cycle heated by propane and the compressor system that Bart suggests. I used an ordinary RV propane fridge in Baja for several years and it just ran with zero issues. Two cubic feet and used a 20lb. bottle maybe ev...

Re: Hot wells

My hot well is narrow and deep. Narrow from port to starboard, that is. Maybe 5 or six inches wide. I have no problem, with rolling in a seaway or boat wake. The float seems to ignore such things. And it controls the level to within a few millimeters. I am most satisfied with my float valve which wa...

Re: Hot wells

Fred, Thanks for the clear explanation. I've gone through this many times with interested spectators as well as boat owners. Your way of explaining it will help. Another way to rationalize the hot well float operation is to say that the sum of the water in the boiler and hot well is a constant subtr...

Re: Vacuum gauge location

A bit off topic but when doing a winter drain I have given up on compressed air. Besides multiple disconnects in the piping and a final warming of the boiler, I have made an adapter fitting for my wet or dry shop vacuum that includes a short length of clear tubing. Volume rather than pressure is the...

Re: Hot wells

On my little VFT-40 my hot well holds about couple of gallons max. It seems quite large enough. Relatively tall and narrow. If I forget to open the boiler feed isolation valve (about once a year!) it takes several minutes for the hot well to fill up the remaining three or four inches to overflowing ...
