Thank you, Tom! ... I'm pleased I haven't been forgotten!   :wave:

Don't forget, you can now see any/ all Pbucket pics. Simply by Installing the appropriate add ons.

Firefox.....  https://addons.mozilla.org/en-US/firefox/addon/photobucket-fixer/
Chrome..... https://chrome.google.com/webstore/search/photobucket_hotlink_fix?hl=en

What a tremendous own goal, Pbucket have scored!  :loco:


So..... While thinking what to do, about the detached flange. I set to, making the cooling fins.

Around 4"/100mm diameter.

Started with, square, 5mm thick blanks. And, one off at 8mm thick, to screw to the bulkhead.

Using 3 stops, on the mill table. Means I can locate/ relocate all blanks, accurately. Every time......




Making it easy, to mill off the corners. Instead of sawing......




Also, to drill a central, 6mm hole.......




A piece of 4" dia steel, in the chuck. Faced with wide insulation tape. Plus a lump of spare nylon......




Friction turned the remaining corners away........




Giving, a handful of discs, all the same diameter.


Moved onto the mill.......




Removed the centre areas. Just undersize, to the hot cap o/d of 47mm......




Parted off, Five, 63mm dia blanks. From bar stock, and removed the centres, too.......




After finish boring, on the lathe. A quick mock up......




I think that looks ok.....  :thumbup:

Thanks for looking in......

David.

 It looks good but I'm puzzled!   :scratch:   :scratch:   :scratch:   :scratch:   :scratch:   :scratch: 

Is it a VFD for the lathe?   :lol:   :lol:   :lol: 
Best regards,

I eventually, got my head around the hot cap, sealing/ retaining problem.

Finding a piece of correct diameter, tube. (It just happened to be bronze). I silver soldered a ring, to replace the original flange.....




Recessed, the new holding flange.......




The cylinder/ spigot, protrudes through, by "a couple of thou'". To make a positive location/ seal, against the bulkhead.......




Held on, by three, neater than original, screws........




Secure......

I hate to see engines, held onto their wooden bases using, obvious, wood screws. I prefer engineering screws. Button heads, look ok.

Or, in this case. Countersink.......




The two rear fixing holes are now, under the bearing pedestals.

Had to drill a central hole.......




I drill, clearance holes, for the screws.
Underneath. I counter bore 15mm deep. The same diameter, as the nut's a/f measurement.

I can then pull the nuts, captive, into the recess......




Thanks for looking in!

New, improved, crankshaft location.....

The two uprights, are made from 6mm thick angle iron. Cleaned up, square, on the mill. Dowelled and screwed in place, from underneath the base plate. Allowing removal, and accurate replacement, when necessary.....

The two, outer bearing housings, are a sliding fit, in the uprights. Held in place with slidelock........




The inner bearing housings, slide over the smaller diameter.......




Butting against the upright. Also, held with sleevelock.......




Should be much more effective than the wobbly, original assembly.

Thanks for looking in!

The crank assembly, is finished....




It cycles nicely. No tight spots.......





The flywheel, is next. At 7" dia. It's a little on the large side, for a mini lathe......




The original bore was unsuitable. So, I drilled out, oversize, and plugged with a piece of m/s. Held in with the ever faithful sleevelock.

The rear boss, held in the chuck jaws, has been machined nicely true to the rim. Allowing me to set the rim running, within a thou'.

Now, I'm starting to open up to a 10mm dia bore. Hopefully. Perfectly true to the rim......

We'll see......

Boring shallow recesses, for each size of drill. Then the 10mm reamer. Held them all, true to centre line.......




After re assembling. Time for a quick test run.......

Thanks Stew!
I think I might be getting the hang of these things. After all this time.....  :thumbup:

We are, "normal", here, thanks. Hope the same goes for you. Over your side of the Pennines.
