Title: Valve angle Post by: samotorsport on April 11, 2020, 20:25:59 pm Hey gents , i wanna build myself a jig to put the Original VW cylinder heads on to drill out the valve guides on the milling machine in a proper way . Does anybody know the angle in which the valves a sitting in heads by any chance ? I read the comp eliminator are at 9 degrees , not sure if stock ones are the same ?

Title: Re: Valve angle Post by: samotorsport on April 11, 2020, 21:26:55 pm That s actually a smart idea !
Never thought about this up to now, but i think this might be the best solution ! Thanks very much i will do something similar !

I thought about the pistons too , no need for the moment but better having it then needing it ;) My only Problem right now is to get the material to do stuff like this , as the shops are all closed (same as everywhere) What color do you use to mark up ? The red one , i always do it with an Eddingmarker but that is not half as proper as yours .

Title: Re: Valve angle Post by: wph on April 12, 2020, 11:58:31 am I use Sharpie Magnum marker pens as a color, couple of layers give a nice, rich red colour.
Pistons are Wiseco 98mm custom blanks with 10mm of extra material on top of the crown, this is how they ended up[attachment=1] Title: Re: Valve angle Post by: samotorsport on April 12, 2020, 12:12:47 pm Very very cool !!!

Nope, domes are just for bumping up compression on a pair of heads without flycutting them too much. I may have to touch them up after the final mockup of the engine, piston to valve clearance may be too close. When done, I'll get them digitized. Way too much work for another set with a manual lathe and mill. |
