By the way, I've got a motor mount that was originally built in Ardmore that I'm tuning up and will send your way - no cost.

Thanks for the motor mount.

You'll get cracks for sure originating at the hole locations. The manual shows attaching the aluminum framework to the bows only, 90 degrees around the bow from the canopy sides. The canopy is glued in place. Same with the front windshield pieces.

The master manual that I have here doesn't show that being the case, but we all know that the manual has had numerous errors and rewrites and quite possibly the version you have may this in it. Let me know. Ed ________________________________ Message 5 _____________________________________ Time: 12:12:33 PM PST US From: "Harold Anderson" Subject: RE: FEWMustang-List: canopy questions --> FEWMustang-List message posted by: "Harold Anderson" Ed, My drawing shows the canopy through bolted at the top and sides with 10-32 screws. I cross referenced this with some pictures I have on actual P51s and several of them show screws along the top and sides of both the canopy and windshield bows, so I assumed that the drawings were correct. I am going to over size the holes to relieve some of the pressure from the screws, I will use the 60 degree bit that ken talked about to open the hole. If I'm doing something wrong let me know.

In fact, the front windshield pieces are so securely held by the surrounds. (No holes, just rounded notches) that I question whether they need to be glued. Is the new Web site up yet?

I'm concerned that Andy's canopy is going to crack no matter what precautions he takes now that holes are in place. I received your alternator yesterday (nice!) and will get a pulley on it early next week and send it, the governor and bracket, and firewall water pass-through up to you at that time.

I could grind or cut out the holes and make them like windshields rounded notches if you think that would help. I have not found any cracks in the area of the holes as of yet, the one crack that I do have is not related to a drill hole.

Using a fine sanding drum on a Dremel tool makes them nice and smooth, and also heats the edges slightly during the process, rather than chipping. As for the canopy, I don't know. I'll defer to Ken Gottchall on this one.

Depending how close to the edge you drilled the holes, you might be able to trim a strip off and eliminate them all together. It doesn't take much to hold the canopy in due to the fact that there is so much area to bond.

I'm glad I've help. As a general rule you do not want to drill into clear plastic unless you absolutley must. You will not see any cracks from the drilling. They are microscopic and will show up many months ahead when vibration is introduced. color plastics are not generally affected with this craze problem because a rubber based additive is added- but clear is different. If you already have holes in canopy, which you should not have,I would recommend that the holes be redrilled much oversize with the 60 degree bit only,not champered or notched, so that the attaching screws DO NOT TOUCH THE plastic either plex or Lexan. Don't notch or otherwise affect the existing hole other than enlarging. Lexan for your windscreen is JUST as prone as plex to crack propogation even though it can stop a 45 bullet. Don't ask me to explain that one but it is fact. Your loyal plastic engineer.

Eliminating holes is best option but if you trim stop whenever plastic sawdust becomes other than powder sort of crumbly. Wait 5 min for blade and plex to cool. Never push saw thru material, sort of nibble if you get my drift.

This canopy has a noticeable gray-brown uv coloring to it.
