Re: Whistle!
Thank you for your advice, cyberbadger. First of all, I'll make a cutaway drawing of the whistle: 1. I've got to verify if the thickness of the steam pressured parts is suitable for a MAWP of 10 bars / 145 PSI. 2. Then, if possible, I've got to determine how to place a stuffing gland on the valve s...

Re: Whistle!
I have seen and repaired a few whistles similar to this one. Typically , but not always, a whistle that has a lever like this on was used on a horse drawn fire pumper.

Re: Tiny Power M Twin Build
Well I "HAD" some really good photos od boring the eccentric straps but somehow I lost all the photos on my memory stick. So I retook a couple. The eccentrics are now inside the straps and turning. the other photo is of the HSS tools that I used one is to cut the groove .189 wide and the o...

Re: Tiny Power M Twin Build
Finished up splitting the eccentric straps today. Squared up the strap in the vice then milled the top and the tops of the bolt boss. http://i284.photobucket.com/albums/ll14/FrankRathmell/Tiny%20Power%20M%20Twin/DSC05148_zpswuqsrbub.jpg Then found my edges and made the offsets to drill and ream the ...

Re: Tiny Power M Twin Build
Turned the eccentric straps down to thickness on the lathe and then went to work on the mill. I did not take any setup photos but I will take some on the next three straps. I experienced some real frustration "finding" the finished piece within the casting. Either the mold collapsed a bit ...

Re: Valve Train Identification
From a practical standpoint, using spur gears to drive the eccentrics might get pretty noisy at speed. Slide valves can have pretty significant forces; piston valves of course don't. Note that this sort of gear is not useful for adjusting the cut-off, only for providing forward and reverse; it's ak...

Re: Valve Train Identification
I'm thinking it might be the throttle .wsmcycle wrote:I see the shifting lever in the lower picture that allows you to change the relation between the the crank and the valves. Interesting! what does the crank in the upper picture on do?

Valve Train Identification
Can some one name this style of valve train. I think I understand how it works . The reversing lever rotates the eccentric shaft and eccentrics but the gears stay engaged with the drive gear on the crank. This is a model engine with 9mm bore x 12mm stroke. Just wonder ing what its called and if it w...

Re: Tiny Power M Twin Build
I decided to do something a little different tonight so I built a small whistle, mouth blown its 1/2" dia.
Just thought I'd share.

Re: Tiny Power M Twin Build
Well todays shop time came to a close way too quickly. But! I managed to set up and drill and tap all the set screw holes in the eccentrics. http://i284.photobucket.com/albums/ll14/FrankRathmell/Tiny%20Power%20M%20Twin/DSC05129_zpsaemnimbm.jpg http://i284.photobucket.com/albums/ll14/FrankRathmell/Ti...
