Hi Kim,
 Nice work & great progress! Keep up the good work!

On the shim leave it as it is! The orginal full-size drawings I have for my project has brass shims on the plans! So you are spot on to full size!

Cheers Kerrin

Your Own Design / Re: LONGBOY'S "SQUARE FOUR" MODEL GAS ENGINE.

Atmospheric intake valves seem to be winning in my designs. Even more so integrating into SQUARE FOUR being to the inboard of the cylinder heads. Space being at a premium here for another cam drive.



Pair of aluminum flat stock pieces (from a previous model shown) sandwich the valve guides sealed by O-rings between as well as the mounting to the heads with a brass tubing between these valve blocks and head.





Long machine screws adjacent to the ports hold the blocks to the heads. With the intake plumbing in place, there is no room for a screw driver or Allen key to mount them to the heads. To get a grip on the screws, I straight knurl across 5/16th threaded rod. Drill and tap 6-32. Cut to a short length and thread up to the head of the machine screws with epoxy to lock them on. Now I can tighten down with my index fingers!  :ThumbsUp: I use the same type finger nuts setting rocker arm clearance too.
I'm going to need some short 90 deg. elbows right out from the carburetor port side from here. I can make them.....or see what my friendly ACE Hardware store has to use.........

Thanks for the input Dave, Chris, and Don,

I like the JB Weld idea... Yes, making the added part a bit larger would be a good idea, Dave, thanks.

My one concern would be how the JB Weld would hold up during powder coating.  The spec says standard JB Weld is good to 500F so it ought to be OK.  The max you need for powder coating is 450.

Does anyone have experience with powder coating and JB Weld?

You’ll make the right decision Kim. Just think it out but like Dave said silver soldering something could go wrong. Myself I feel comfort enough to give it a try and silver solder, if it failed start over it’s the risk I would take. Just my two cents.

Nice motion Kim!

My first thought on the shim would be to make it from steel and bond it place with some JB clamped up tight. Make it a little oversized so it could be dressed back down to the original surfaces.
Silver solder would be ok but there is always some risk involved with something going wrong on your finished part.  :wallbang:

Dave
That was my first thought too. Or a little steel-colored paint on the brass edge... Not that I have ever done that. Today, anyway!
