I worry someone bought it and will be flipping parts for almost as much as the engine. Especially because they're not correct, it gives me the vibe that they are out for one thing only..

 

[Edraven99]

Just because it was the wrong engine for Obi emitters, does that also mean its wrong for the flame tube/IG88 head? Maybe it was bought by some fanatical droid builders.

Wrong for that as well unfortunately

Can it be seen by the photos? How? I keep comparing it to Derwent mk8/9-s online and i dont see a difference. Of course I am not even on an amateur level with jet engines, I’m just trying to figure out.

 

[onderon]

I just got an email from an australian museum and they confirmed the engine is a Derwent MK8 engine. (I emailed them the photos)

So there are different type of Derwent 8’s with different flame chambers and balance pipes?

 

[corliss1]

Yup - just the presence of the engine itself doesn't indicate it has the right parts.

I could be wrong but I was under the impression that the correct BP’s were an upgrade/fix for the original engines later in the war and so may not have made it into every engine by the war’s end.

Interesting...

Hm..so my question is how can it be seen from outside, if indside the upgrade was made or not?

 

[DrkSideTndncies]

If I’m not mistaken (learned from a previous engine find I made and ultimately passed on) the only way to tell from the outside is to caliper measure the OD of the balance pice itself. It should be accessible from the outside of the tubes and the upgrade is a larger diameter than the original version. The original had fewer porting holes around the main opening hole and therefore is smaller. I have photographic comparison but not my original photos so won’t post here, but it’s a pretty noticeable variance.

Found some of these dudes. Or dudettes, I don't know. Need to get some machine screws in there and then they'll be ready to mount. 1975 date codes.

 

[cdyoung]

Great! I’m in a hurry to see those attached in the Graflex clamp. Please post photos of the machine screw installation if you have time.

 

[corliss1]

I haven't decided if I want to get fancy and try the wood block clamp system and actually bore the insides out, or just smooth the bottoms a bit and epoxy the screw on. I do have plenty of non-sacred TO39s to play with to practice though, so that's likely where I'll start.

 

[corliss1]

Initial tests look good. I didn't clean it up, but it's more than enough to prove it's gonna work.

Nice pick up, what is the height of the Cans, I picked up some Soltron's a few months back but the Can height was to high compared to the reference pics.

 

[corliss1]

I think these are definitely the taller variety. Could you post the official height we're shooting for?

You’re looking for Op Amp cans and unfortunately I haven’t been able to find Solitrons in anything other than the tall TO-5 cans.

What David said, these are the Op Amps I have on my Obi, Troy Seneca did the mod on his Mill for me.

 

[corliss1]

cdyoung - they look about like this

a hair tall, but close enough that I'm fine with putting them on there. I suppose you could always grind off the bottoms a bit and no one would know the difference.

 

[Serenity]

I still think the washers go around the cans and not under them.

 

[JayCVenlo]

Here's my JI. Instead of on the left, the manufacturer's number's on the right, crescent moon ish. Number 93 ?

Do they all have markings?
