I drove over to Fremont yesterday and picked up the baffles. I needed one set for Martin's plane, one set for Brian's plane, and one set for Ned's plane.
The cost for one set, 13 pieces, was $1600.00. The cost for 5 sets was $3000.00. The cost for 10 sets was $5,000.00. Yikes. $500.00 a set. Anyway, I have them now and they are beautiful. They come with the part number stamped in them. The fabricator brushed and alodined them too. They are very nice.
Van's sells a complete baffle set for $275.00. They aren't finished at all, just punched out and bent. He has to be either making a shit-load of them or doing them in-house.
I suppose one could fabricate their own baffles from Van's kits but, I can tell you from experience, it will take about 20 hours.
Now, I need to mock up a set and see how close they are.

I bought a set of Van's baffles 3 years ago when I installed the O-320 engine in my Lynx for $200. I think it took me over 40 hrs to install them with 75% of the time on the front baffles and the one over the top of the engine which seal to the nose bowl. The ramps on the front baffles had to be bent in 3 places and much trimming and riveting on some extra gussets to make them fit the Grumman nose bowl. I must have had the nose bowl and cowling on and off at least 20 times or more! The end result was excellent cooling and baffling that is much better than anything Grumman ever built. I guess if I took them off, made drawings and duplicated them you could do it in far less time.

You drove from Auburn to Fremont today? It was beautiful (okay, a few clouds in your direction). You should have flown to into Hayward and I could have given you a lift on your errand.
Best,
Jamey

The baffles I had made were the result of a years worth of trimming and fitting and then turning them into CAD files. I'm hoping they fit out-of-the-box.
I'll know in a few days.

I think the answer is both... Vans fancy CNC machine is shown here...

BTW, how is your RV project coming along, Gil? I forgot, is it an RV-6A or a -7A?
