Next I'll be cutting the slot for the carb bores, facing the bottom side and angling it at 3.5°. Then facing the top, drilling and counter sinking the holes for the allen screws to the head. Will update again probably Tuesday next week
That's why I'm done milling, its probably .25 or slightly under that in my material thats left. I'll see what i can do to the adapter to make it all good. But yes i am keeping in mind the carb angle. I read it should be about 3.5°.wsa111":2628lnp7 said:Nice job so far. My only concern is loosing cross sectional area of the log, vs brazing the low spots & then milling at a higher point.
Anyway you do it will require spacers to get the carb higher & get as close as you can to keep the carb at the same angle as the one barrel mounting pad.
I'm not milling the phenolic spacer. I'm going to mill the bottom of the carb adapter to the 3.5 degrees. Then everything on top of it will be sitting correctly. The phenolic will be added only if i need more lift to clear the valve cover. Otherwise it'll just be the carb and aluminum adapterchad":1f69is3t said:mill the plastic to 3* ?
(after trimmed to 1 inch)?
That is what I used on my home made full sized hole in the manifold tri power adapters... It sealed with only .090 but only along the sides of the manifold at the round hole ... The full name is permatex aviation form-a-gasket #3 if you google it and look for the data sheet you can see, but a quick run down is slow drying ,non hardening, continuous use -65f to 400f. Retains effective properties in contact with gasoline, motor oil, trans fluid ethylene glycol and sea water.StarDiero75":1zeneaav said:Fixed it! Ok but like was said earlier, is using sealant a good idea around the gas?drag-200stang":1zeneaav said:I would like to make a correction, permatex # 3 is what I was thinking about , it is thinner than #2 and brushable...#2 is a little thick for good fitting parts .
Star can you edit the quote to #3.. I like to make things as factual as I can.
Thanks....PS the adapter is coming around nice.
Thanks, i spent a lot of time with a file rounding everything
I hand fed it. And mine was 4 flute. I was amazed at the surface finish, it was so smooth!chad":dhx44huf said:"...i used a 3/8 carbide end mill on a vertical mill at 500 RPM..."
4 lip (double end) end mill here. The 500 rpm seems slo but depends on speeds'n feeds (of course).
Some 'hand feed'. Others 'automatic table'.
Thanks a lot man. My hands hurt and are coverned in aluminum. I now hate aluminum haha. But yes it feels amazign to have done it all. Thank you very muchSoldmy66":35ittfnv said:Please accept my praise of your efforts. Everything you've done looks great - and I hope it gave you a sense of accomplishment.
Well done.
Haha i thought the cake was a nice touch lol.chad":36aw4nvs said:that really takes the cake proof is right beside !). 8^ )
I C in 1 pic another adapter below, yes?
Do U have a shot of that to look at?
IS whats shown so thick to get the carb links above the V/C?
Thanks for showin it all.
I'll be using headers so i can't run one anyway.bubba22349":2nmii5tx said:In your tuning experiments remember that on a street only car the EGR valve is quite useful in helping you to get the best in MPG. Plus since it's only operating at the higher hiway cruise speeds it doesn't really have an effect lower speed power. Good luck
