Refurbishing a Maserati 3500 engine.

[landman]

I'm not sure if it is worth a thread but here goes anyway. This engine was given to me by fellow member Gary McNutt as part of a stash of old engines. I want to finish it to display. Here's what it looks like unassembled.

Doesn’t look like very many parts. I’m sure you’ll be adding some details.

Wow. The Aurora/Monogram kit is pretty fundamental and globby. Tough challenge when you consider there are two plugs per cylinder at this small scale.

Yes, I am a fool for punishment.

this photo is of the Weber carbed version of said engine  -  the kit engine is fuel injected - which is also correct - choose your poison

you'll have to scratch the distributor - you'll need some  .06 alu or brass tube and lots of patience

plug wire - no bigger than .013 - there is an Ebay store that sells .011 wire in different colors -  Belly tanker has the site on his ...  belly Tanker ... build in the land speed / sports car /racer section

I built that kit last year but I really don't remember what I did for a distributor. I'll check on that and see if I came up with a really clever solution (doubt it, though). In the meantime, good luck with it and I'll be following.

If I have any left, I think it will be Webers like those I put on the Aston.

nice Aston engine  - you spent some time on that fan blade ...     - fr the Aurora  DB4 kit ?? 

treat your self to some 3D printed Webers - there are some very nice ones on Shapeways

 and floating elsewhere around the internet ...

[landman]

Spent some time on the oil pan. It sort of looks like the real thing.

[NOBLNG]

Looks pretty good to me.

Built up the distributor and wire conduit. Looking at Greg's photo , I realize the conduit is woefully out of scale

[landman]

Take two. I found a smaller tube that will still accept the 12 "wires". Did two versions. I think I like the one without the nibs best. I will try to do one with 12 holes as well.

Real nice work so far, Pat

[Zippi]

Coming along nicely.

Those wires wouldn’t have to be run continuous.  You could just make a short collar to accept the 12 wires from the distributor and then a smaller conduit (sprue or evergreen?) extending from that collar.  Drill holes in that conduit just big enough to accept the wire coming from the plugs.

I’m not sure which version you are going for, but if it’s like the pic I posted, you could drill straight through the conduit into the head to allow for some adjustment to the plug wire length.

That was my plan. Run the bunch from the distributor to the mouth of the tube. Then a pair out of each hole to the plugs.

This would be my approach as well.

This should be a very interesting and challenging project. I'm eager to see more.

So it was that Greg's suggestion prevailed. It may not look exactly like what he had in mind but that's what it is.?

[landman]

And I found some Webers

[David G.]

Nice progress, can't wait to see more.

Added the clutch, engine mounting tabs, oil filter and generator.

[Modelbuilder Mark]

Very cool to "see" details going in that may never be seen in the end product.

[slusher]

Pat, your really adding realistic detail too your engine.  Awesome work friend..

[landman]

Generator drive belt.

Nicely done !
