Drew here's a pic of a SCCA FP 1275 race engine I built with a Acme palgue on the side of the valve cover, it is expoxyed on, but I'm thinking of a way to better mount them, like SS rivets or smallish bolts and nuts. I left the picture large so you could see the plague good.

Boy that's a pretty motor. /bcforum/images/%%GRAEMLIN_URL%%/smile.gif

That plaque looks nice. Would it fit the little bosses on the top of the standard steel valve cover -- where the Austin and Westlake Patents go on the early motors? Just thinking out loud...

I like the rivet or bolt/nut idea. Would look even more intentional that way.
 
I should think rivits only, nuts and bolts could fall inside in worse case.

Click to expand...

If I went with nuts and bolts, I'd use nylocks, something small like #8s, I've personally tested nylocks up to 9300 rpms with no problems /bcforum/images/%%GRAEMLIN_URL%%/smile.gif Plus some of the factory valve covers had riveted on plaques.
 
Drive screws might be an option. Thats what they use to fasten the nomanclature plates on helicopter engine/transmission housings. Good for excessive vibration, and IF the material you are fastening them to is thick enough you don`t have to drill completely through. Thus not taking a chance on creating some wepage. I believe that in the aircraft industry they are called, round head u drive screws
Nice looking engine Hap.

Look at them here

You could drill and tap the aluminum very easily, Than just use some ss screws and locktite. Than no possiblility of anything coming through the inside. I just yanked my breather fitting out and tapped the hole to 3/8 NPT to accept an AN fitting. Tapped very easily. Same polished aluminum type vlv cover.

Engine looks great BTW
 
C'mon... let's do it right. Have a CNC mill engrave it into the side. and through away those "plague"s in the trash.
 
LOL, an engine by Hap gets a special alum valve cover in the package. I like it.
 
CNC milling into the alloy valve cover would be cool, but adds another chore to the already very long list of thiongs to do, and of course another charge, the plaques are free with the motor. Jack I put whatever valve cover on they want me to, some opt for the alloy, some don't.
 
Original Morris and Austin A-series valve covers used big rivets. Look nice, never fail, original touch.....

I like the rivet idea as well, however, the Hap-Hazard theme is pretty slick! /bcforum/images/%%GRAEMLIN_URL%%/cheers.gif to Hap
 
Hap? A question not meant to offend. Why isn't the motor green? Green lbc motors go faster, don't they?
 
I wasn't in the position to send my 1500 to Hap - so I painted it green instead - came with a warranty to go faster - the rattle can said so /bcforum/images/%%GRAEMLIN_URL%%/grin.gif
