Nice start Jack :thumbup:

I've pulled up a chair to sit and watch...

Regards, Arnold

Thanks Arnold, Nick, Olli, and everyone, comments are well appreciated, and the build is more enjoyable for it. I started yesterday with hopes of getting the crank support structure mostly done, but as usual, there is more than meets the eye, when it comes down to it.

with the crank bearing holes in place and recessed, I started with the bolts which will hold this together to the cylinder. I used a ten bolt circle, with the first and sixth holes perpendicular to the crank, because I have to cut this in half to get the crank in, when it is all done, and I wanted four good bolts holding each half, for rigidity. I didn't drill those two holes, the cut will go right through where they would be, but the bolts are better spread than an eight hole pattern would give

The spigot on the cylinder is an inch o.d., and the clearance for the crank is the bore of 1.375, so the PCD is .645, three thirty seconds larger than the spigot hole, so the bolts are centered in the 3/16ths "collar" inside the crank support. Only eight of the ten holes are drilled, clearance for #4 socket head screws, at .113 diameter, started with a center drill for accuracy, and then finished with the clearance drill.

setting up the cylinder in the vise is an easy task, the V block crosses the vise ways, needing no squaring up holding the cylinder nice and vertical.

Another view of the cylinder, ready for bolt circles

using the same bolt circle as before, with the same pitch diameter, starting holes are drilled with a center drill, again, eight of ten laid out.

another shot of the cylinder being drilled out for tapping

The cylinder done, removed but the shop vac has decided to take up smoking, and won't pick up the swarf, time for emergency surgery.

Some serious disassembly

problem found, brushes stuck with only twenty or thirty years of service, does everything have to have short lives? Spinning the armature with my drill, I manage to get all the burned carbon, soluable oil, not soluable oil swarf and dirt off the commutator, so maybe it will be ready to get back to work now.

Most of the parts so far, never mind the miscellaneous parts from other, not finished engines, but these fit together well.

A view down the well, two sets of holes.

the crank structure sitting on top of the cylinder, eight holes line up perfectly. Now I get to re-assemble the shop vac, clean my mill up some, and then start covering it with swarf again, I think I'll put a filter on the shop vac, it seems to be missing one. That might be how the swarf ended up in the brushes, Electrolux would cringe if they could see where their motor has got to now :bugeye: it's a dear friend, having been with me since I pulled it out of a green box twenty odd years ago, when the previous owner thought it had died. A little cleaning out of dirt, attaching it to a drum, fitting a filter, and a shop vac was born. Almost broke my wallet buying that filter.

Next session, tapping the holes, cutting clearance for the crank, and establishing the shape for the structure, esthetics, don't you know. Ta ta for now, thanks for sitting in on this. :poke: mad jack

Nick, there are a pair of keyless chucks, one for the lathe one for the mill, and the third one, did I say a pair?, for the main drill press. Keyless chucks are great, but they are long, they are also self-tightening in the lathe, sometimes in the mill, and seldom in the drill press. Chris, I would be hard pressed to go back to using a key all the time, although I still have all those keyed chucks, lurking in drawers.
Olli, I couldn't have got it started off this well without your help, you've made it much better a presentation, and I have to say I too enjoy not knowing what something will look like in the end, the build sometimes takes on a life of its own. Somehow, I've gotten stuck on flame suckers, and can't put them down at the moment. I expect to get through it though, but will probably catch some other engine disease immediately after.
All of this has come about because of this forum, and the inspiration provided by so many un-named people building every sort of thing imaginable and I wanted this proper credit out where it is due. Is it kind of weird to be doing this thing of ours, in the middle of Christmas, when we could have clean hands, and be relaxing with friends and family? I guess it depends on whether one's a mechanic or not, at least I'm not on the side of a cold road, fixing brakes on a car, or refitting universal joints on a drive shaft, laying in the wet road.
Thanks for all the thoughts, opinions, encouragement, enthusiasm, and for being part of what seems to be a great big club, spanning things our governments cannot. God Bless all, and may all enjoy the full meaning and spirit of this Christmas Season, as we celebrate. We, more than most people, have so much to be thankful for. Merry Christmas, a bit ahead of time because I tend to be forgetful. :poke: :lol: :lol: mad jack

NickG:
Merry Christmas to you too madjack and everybody on the forum + families.

I'm off to try to finish, well, I will 'finish' the tiny stirling, it just might not work! Had clean hands and tried to relax with friends and family for the last few nights, so time to get them dirty again and get stuck in!

:offtopic:Things are looking up on the car front for me too so I shouldn't be lying on the wet drive under the car with a bit of luck - on a similar forum I've found somebody that will source me an engine and install it for a great price, and the other car (courtesy of my mum to the rescue :lol:) is being exchanged for something tomorrow which is newer, not as high spec but hopefully more reliable at no extra cost! If in doubt - ask mum to sort it!

Well all, yesterday was not very productive, I misjudged the shop vac, and even extreme surgury didn't help, I believe I will have to dig a grave and bury it, with appropriate words said over it, and maybe someday it will be a Darwinian evolution seed, and start a new life form based on steel, aluminum, copper, cutting oil and military green paint.
Nick, I'm glad to hear you may be clearing up those car troubles, and your engine will run, it might take a bit, but one way or another, you will see it run, I feel certain of it.
I also took in a foundling Atlas shaper, which I'd traded off some time ago, and traded back the exact same Bridgeport Milling Head, back, which I got for it. I don't know what to do with it yet, but I'm sure it arrived for a purpose. more to follow. :hammer: mad jack
