Hats off to GlassDave for hauling his azz over here to PA and overseeing a tricky project on my Batboat. I couldn't be happier with the way the whole thing turned out, and we all had a few laughs along the way. I'll leave it to Dave to post his favorite shots, but some of the details are already posted on the Ilmor 725 thread in General Discussions.
Thanks, Dave!

Thanks Chuck glad i could help out. It was good to put our heads together to come up with a solution to a somewhat technical and out of the ordinary rigging situation. Cant wait to get a ride in that rocket ship at jammin on the james.
Again thanks for the hospitality glad i could help the project.Throttles- Cleveland Construction/Traffic Light Racing 377 Talon cat

03-18-2010 01:19 PMWith the vacuum bagging on both sides of the transom, how is the outside kept flat and smooth?

Its all in the setup. When i got there the first thing we did was to bond in a first piece that was the exact size of the original hole but only about 5/8th inch thick. The existing fiberglass and wood was cut back and recessed and "shelf" in two new inner and outer pieces that were bagged on. The first bonded in piece effectively gave us a solid platform to work out from. Bagging transoms can be very tricky, you never know how it was done originally and leaks can come from anywhere. I had one persistent air leak on this one that came from an old bilge pump mounting hole that i missed. Had to find and isolate it quickly.
The outside was also kept flat by carefully cutting the laminates to match the scarf as best you can. We got really close on this one. Chuck put a few miles on my Kevlar shearsThrottles- Cleveland Construction/Traffic Light Racing 377 Talon cat

It wasn't happy with the Kevlar, but the hole is cut, so I guess the bit wins.
Bosch #85911MC, 1/4" diameter x 1" cut length Upspiral straight bit. About $20 from Lowe's. It's 2-1/2" overall, so if you pull it out to cut through 2", there's not much left in the collett, and the vibration tends to make it walk out. If I can find a longer one, I'll let you know. I'm in the market for one, after I knocked the router off of the bench and shattered my bit.....
McMaster numbers:
27395A95 ($21.75): 2-flute, 2-1/2" long, the same as I used
8711A11 ($49.85): 3-flute, 3" long
3334A13 ($79.73): Diamond pattern, 2" long, specifically designed for cutting carbon
8785A24 ($14.12): Diamond pattern, 2" long, specifically designed for composites
8796A12 ($36.95): 40-grit diamond coated, 2-1/2" long, for composites and ceramics.
The last one (8796A12) is probably the best choice.Last edited by C_Spray; 04-06-2010 at 01:04 PM.
