Yes the difference is in the angle of the pitch. BSW = 55' and UNC = 60'. This is where your thread pitch gauge can come into play. If your BSW fits perfectly into the old thread with no light gap that is the one for the job. So as suggested use a thread locker (Loctite or similar) to ensure it stays where you put it.
Again gas does have a tapered or a parallel thread so be careful.

Resurrection of a Deutz MAH 914, 1952? Lets see! 5/8 TAP & PAINT
« Reply #166 on: October 04, 2022, 02:25:22 PM »
Cobba, Gentles

5/8 tap arrived, and.... job done! (Remnants of old stud got out and I was right - one thread of casting broke and jamed the stud)

2nd coat of paint and the German starts to dress. 1st coat at head also.

Some pics for the show.

Cheers

Well done VP, second coat looks real nice. Hope your sciatica has improved after you river trip.

Resurrection of a Deutz MAH 914, 1952? Lets see! CUTTING GASKETS

Bob, Gentles

While waiting for parts and machinist shop its time to push forward some tasks in order to start put thing together.

Tomorrow will have flyes sandblasted, and paint job will continue.

A few pics for the show.

Very pretty VP, looks like you have started cutting gaskets. I hate cutting gaskets, especially where end float is determined by gasket thickness, finding gasket material of the right thickness can be a nightmare and often involves multiple gaskets between mating surfaces.

Keep up the good work, no surrender!

I too mostly cut my own gaskets and yes getting the correct thickness material can be a challenge and requires a few sheets of various thicknesses. Then they do have a tendency to 'dry out' and become stiff and won't compress like they should. In a case like that I have made the gasket and then soaked it to soften it, let it partially dry the fit.

Hi Cobbadog, I generally soak all my gaskets in aircraft gasket sealer, messy stuff but it works. Don`t try it on exhaust gaskets!

Yes I use the same sealer but still soften the paper first with water and a day or so later then fit it.

Resurrection of a Deutz MAH 914, 1952? Lets see! STRAIGHTENING HP PIPE
« Reply #173 on: October 10, 2022, 09:38:38 PM »
Cobba, Bob, Gentles

Oil resistant gasket paper can be softened and straighten with water? or a spray of water? My thick paper is well curled.

Today finished to put on his way - or best way - the HP injection pipe.

3 pics of how it was,

and I realised it was wrongly put in place,

so I managed to give it the right way.

Cheers

Hi VP, that HP line looked badly out of shape and alignment, looks much better now.

Nice work with the new injector line. Yes the gasket paper I have is thin, around .5mm to 1.0mm and can be softened with water. When a roll of paper curls up it is because of the moisture content drying out.

Resurrection of a Deutz MAH 914, 1952? Lets see! FLYS ARE BACK AND PREP
« Reply #176 on: October 11, 2022, 11:14:44 PM »
Cobba, Bob, Gentles

Flywheels are back from sand blast (or glass or something else now allowed). [not cheap this job!]

We can see now the questionable quality of the casting (flys are straight forward molding and pouring, I think).

Nevertheless got them rim polished with scotch-brite disc on angle grinder, and put a coat of varnish. Walls will have same color of engine,

And the pulley also inside. Outside it already got a coat of varnish too.

A few pics for the show! (facility, casting, stamps, and primary)

Cheers

They have cleaned up nice. It is a shame about those porous holes but a little bit of filler won't upset the balance and would look nice once painted. One of the popular mediums used now at the blasters is crushed glass. Very abrasive but I use it in my small cabinet and after it has been used a while it softens and is quite good to use.  So far so good with your progress.

Cobba, Gentles

After primary coat, gave 1st coat of "Brown red" to flys and pulley.

Cobba, no need to put filler - I like more cast iron as it got out of mould.

One pic for enthusiasts!
