From Kits/Castings / Re: Marcher, a twin cylinder marine steam engine
« Last post by Moxis on Today at 08:34:07 AM »
Thanks kvom, that is a good information I have to keep that in mind. So that absolute accuracy is not necessary, good!

About dimensioning.  All the measurements on the drawing are naturally imperial. But we are living in a metric country, and all my tools like drill bits, taps and dies, reamers etc. are metric, so I have to slightly adjust the dimensioning. This means for example that 5BA threads will be made M3, 8BA M2 and so on. I hope this does not bring unsolved difficulties later on. The dimensions of parts can easily be converted into metric, calculator has been invented.

Enclosed are photos of the main drawing of Marcher and castings which are included into the package.

Hints, Tips & Tricks / Re: Holding small bits in the milling machine

That's a smart solution, I use an ER-16 chuck to hold small drills and for workholding an ER-32 collet block and the collets I use on my milling machine. I also use the ER-32 collets for workholding on my lathe, they are vesatile.

Well, the new valve body with o-rings is a total failure.   I think I need to increase the dimensions of the reversing valve or come up with a new reversing mechanism.

One last video of the Six Cycle engine running with the pulse unit. I put a lighter spring on the gov to slow her down. It will now be put back on the shelve for now.

Looks fine for me.

I can also see the drawings from the initial two links.
I have to admit...I don't think I checked last time.

I think you're good to go.
Ok, I've redone that URL again and I've check that post from 2 different computers using 2 different accounts.  It works for me now. 

If possible, could you please try it one more time?

Sorry for this mess!

After this I still have a " minus " sign. Everthing esle shows. 
I see all now.  ;D

Sorry for all the issues from me on this!

No worries. We've all been there. And I've returned a few times.
