Any amount of cooling you can get over those larger servos the better, IMO. I milled out the lower case on a Seiko for a friend of mine, and I really think it helped the centering, as well as removing a little weight too!

The SMT components have no issue with the dust and dirt....... But the servo pot, that is a different story.

Great info on the Seiko setup possibilities Bob! Thanks, Matt

Really wonderful!
Congratulations on the great project.

Good work Mikey!!! Keep up the good work!

What tools were you using to cut and mold the foam the way you wanted?

Thanks,

BoneDoc · 10-29-2009, 02:53 PM

Bob,

Would it have saved even more weight if you move the motor box all the way to the front right with the engine mount, and have a shorter cowl? Just curious.

I used just a 90 degree angle grinder to take the bulk off, wire brush, 36 grit sand paper, and 80 grit sand paper, thats it.

It would, but I think it might change the way it would look with a really short cowling.

Bam Bam · 10-29-2009, 10:34 PM

yeah, it definatly would not look right with a short cowl!

sensei · 10-29-2009, 10:42 PM

I had the chance to put a QT. 1/2 of high build prime on the master this afternoon, I also put a single guide coat, so I guess I can spline sand with 80 grit this weekend.

Bob

Vic3D · 10-30-2009, 02:21 AM

Pardon my ignorance on building Bob, but are you going to make a negative or positive mold for the cowlings?

Hey Vic,

I will be making a female production lay up mold directly from this master once I finish the surfacing.

SWEET!!! That looks familiar......

sensei · 10-30-2009, 07:39 AM

Yah, The last time I was doing this was on your cowling I think.
