@Jason,

Very nice oiler. How long did it take to make it?

Mark – as a bit of ‘an old duffer’ myself, I second that! I recently made some replacement carburettor linkage pieces for a McCorrick tractor. After working how I could manufacture the butterfly valve linkage and fabricated the said item only to find I’d made a mirror image of what was required! 😱 😳🤣

It would take me 3-4 days on my ML7 with vertical slide

Still much to learn…

With the replacement governor latch made and a few tweaks to the ignitor it runs as well painted as it did in bare metal. It does sound a bit wheezy with quite a lot of induction noise probably due to it being happiest with the choke plate covering about 2/3rds of the carb inlet. Colour also looks better in the video.

Did a bit more on the Vertical Cross engine, assembled the swing arm assemblies. got a tight spot somewhere as when the crank is at BDC there is a definite binding, suspect some other measurements are out, possibly the swing arm assemblies…

An engine of this type is on my bucket list. I used to have an old ME with a picture of a small colliery winding engine in this style, but I just can't find it.

Yup the tight spot is on the swing arm assembly! … looks like pin misalignment & difference in length … when added rotational pressure is applied ( finger pressure on the shaft, the soft soldered joints break ) … so much for 5 piece soldered swing arms… so it's a rehash with a new pair of swing arms… this time I'll utilise Jim Nic's method, or similar, ah well! you get a run of those days every so often…

Made a new "drill stand" today.

It has spiral flute tap, spiral point tap, tapping drill, counter bore, clearance drill, sized drill, pre-ream and reamer.

Covers M3 to M12. Saves wasting time hunting through tins and makes it more likely that I will actually use the right tool!

Once again, I take a picture "portrait" on my phone and it ends up on its side. I don't know……..

Use your pc's / laptop photo editing app W10 has free one built in, or use paint… copy image, load into Paint, rotate, 'save as' in preferred folder…

Where did that UFO come from… Have you informed SETI ? … oh drat, I guess it's a tennis ball on the cross feed handle of your mill…

Its something I do on my machines that are not being used. I've only got a small shed and two lathes, a mill, bench top drill, bandsaw, bench, grinders etc so space is tight. I split my head open on a machine handle, bending over and standing up a bit quick!!

The difference between banging a tennis ball and a machine handle, is quite something!!

Finished up the 'new' swing arms today, made from one piece MS, still have to finalise bits on it & polish up but it's getting there…

I haven't made a lot of progress on the Hasbrouk Rocking Valve Engine of late. For one thing other priorities have got in the way and for another I haven't really taken to this project like I have with all my previous engines. However I like to finish what I've started so on we go. Here are a couple of "family shots" of the cylinder and crosshead and the crankshaft in its bearing pedestals.

I am making the engine smaller than the original drawing so the next step is the connecting rod and then I can confirm my dimensions and get the cylinder and crankshaft mounted on the baseplate.

Looks like you are making good progress to me. I have not done a rocking valve engine but do have one 85% drawn up to make at some time.

Made up the Eccentric and valve parts for the Vertical engine I'm working on as and when the fancy takes me.

I finally, after 6 years, got to grips with the DRO on Crusader!

I've only ever used it on one tool at a time, because when you power off and move things, the position is lost. I can now just use tool 1 and set the size, the tool library then updates.

I even made a setting tool, its just a bit of sleeve with bearings inside. I can just touch the O/D or bore, when the sleeve stops rotating. The size is then just inputted. I may have to buy some more tool holders to take advantage of this!! Its got a 200 tool library after all!

I just wish I'd got my head around this sooner!

Don't your scales have index marks on them? As far as I was aware, most do. Then, if you simply move your slides / scales past the index mark after powering up again, the DRO will pick up its absolute coordinates.

If you ever shorten your scales, you need to ensure you don't chop off the bit with the index mark otherwise you'll lose the ability to re-zero.
