Thread: 2/3 Harley Davidson 1920 JS

It was a very enjoyable day working on the Harley.
I repaired and modified the exhaust valve covers and rebuilt the pushrod covers.
Now it's starting to look like an engine again.





I'm really happy with the improvement in the detail and finish of the engine so far.
As with the rockers I'll leave the valve covers in primer until the engine is finished.
Then I'll give them a coat of nickel.



The Splitdorf sparkplugs will be the next to be made.
I'll have a ton of fun making those lots of small detail to chase.



Cheers
Trev.

Just sayin....

An awesome rebuild Trevor. I think the timeframe for it is going to need extending, considering all of the fine work you are doing; the Brough can wait, we have Harley up to plate! And it's swingin' for the bleachers...

potatoe cakes, fritz, stoby poles and deli's

Looking good btw

I'd go along with that mate.
It's going to take sometime to gather up all the info needed for the Brough.
And I'm really having a ball with the Harley at the moment, so I'll make sure I finish it completely before starting anything on the Brough.
Besides I reckon the Indian and the Harley standing side by side would look really kool!.

Although now that you've made all thoughts baseball references,
I'll have to make sure I use some more of the bat that I built into the Indian (aka Slugger) on the Harley.
Which is probably fair enough because what ever I build we all know it's ending up in left field!.

Cheers mate

Don't take the bat to all of the replaced parts in frustration at the end of the rebuild, or yourself

I worked on the sparkplugs pretty much all day yesterday.
Tricky little things with lots of fiddley bits to drive me nuts (Luvin it).
Not a lot to show yet although I thought some maybe interested in the way I make the main section of the plug.

The Splitdorf sparkplugs have a tapered hexagon insulator.
When I made the ones for the Indian it took me quite awhile to workout a relatively easy way to make them.
I first tried drawing it all up onto a piece of timber, but the part is so small you couldn't keep track of all the lines.
In the end I glued a nut in the centre of each end of the timber, one of them smaller than the other to create the taper.
I made sure that they where as square as possible, and then ran the sides through on the bandsaw as close as I'd dare to the nuts.
After that I used a sanding bloke to take each of the six sides down to the nuts.
Then I just snapped the nut off each of the ends.



It's a simple way to make what can otherwise be a difficult shape.

Great resourcefulness. Coming up with extraordinary ideas on how to achieve outcomes is the thing that makes model making great.

Well Done

Got some paint onto one of the sparkplugs but it wont be staying.
I made the convex pieces around the centre of the second sparkplug (to the left in primer) more pronounced.
It looks much better than the first one I made with a shallower appearance to them.
So I'll strip the paint off and redo it, no great drama the parts are only made from a Corn Flake box.
The sparkplug to the right is one of the original ones I had on the engine.



I gave the plugs a test fit and I'm really happy with them!.
But then comes the "except".
The boss that the sparkplug goes into on the left cylinder head is obviously smaller than the one on the right.
The base of the left plug is larger than the boss.



I'll need to take the head off and rework the boss then give the head a respray.
Not so bad it should only take a couple of hours to fix.



So hiccups aside it's all good.

Making the plugs is really "thinking outside of the hexagon"
Well done!

Looking good trev,

If you need more of the one on the right I can ,an age that I reckon

I reworked the boss that the sparkplug fits to and patched up the paint work.



I also gave the second of the sparkplugs some paint.



The convex pieces around the centre of the second sparkplug I think look a lot better being more pronounced.
So I'll definitely change the sparkplug on the right to match it.



It's good to get that little oops out of the way!.

Refine work on the spark plug.
