Yes it's only 6 bucks for each issue, I think I ended up paying 24 bucks cause the plans reference articles in #7 and #8 the plans are in issues #10 and #11.
It's good to support the magizine because the have really good information that passes on years of experience from other builders. All in which is invaluable to me!
Here's where I'm at in the project!
I've built all 4 plates for the crankcase base.

Top plates milled at an angle, and I have a 6x26 knee mill with a Newall DRO.

Thanks
Guys I picked up the subscription and got issue 10 and 11. But looks like I need to get 7 and 8 now. I'm gathering up the materials now. I know a guy here in Ohio that made his a twin cam seen the video but would like to see in person. He just does not want people over at his shop.
Thanks Again
Keep up the good work

Maybe you can talk him into showing it at the show in Zanesville this October.

Make sure you cover your ways and cleanup very good once your done. I seen a trick that Keith Fenner did from Turn Wright Machine (YouTube) is he turn his cutter over and ran it in reverse so the chips would go straight down and could be picked up with a vacuum. Looking great I cant wait to start mine.

I have the cylinder tapered and it's to the mill for drilling holes.

I'm a little stumped on building the cam housing. To get the dim on the angles which are 25° each side, the dim to the top where the angle starts is .947 but there are r.063 on each corner. So to find my dim do I take .947 minus the radius of r.063 to get .884 then move from 0,0 to .884 in the Y direction then move the table 25° and make my cut moving the x axis?
Long story short I'm trying to find the Y dim from 0,0 to make my 25° cut.

Or ? If you take half the distance of the .604 dim(.302) and.947 dim and plug into a triangle calculator ok get .898?
So would the dim be .898?
Ugh headache

Only the two outer corners are radius 0.063. The radius at the top is .147" with its ctr in the middle of the bolt hole that is 0.800" up. This gives the overall height of 0.947.
If you rotate your table 25 degrees then set the cutting edge of the tool 0.894 from the centre point 0,0 it will meet the 0.147" rad at a tangent.
I actually cut these angles and did the cam follower holes all in one setting with the part mounted on teh jig shown on teh drawings with the rotary table mounted vertically. In this case bottom of tool 0.894" above the pivot point.
