Making model I.C. engine valves. Silver soldered fabrication

How I make valves for my model engines using ground stainless steel bar. They are made in 2 parts and silver soldered together. This is easier than machining from a solid bar.

My friend just found you. Great parctical work and good results. As I am about to embark on my first modelling adventure your videos will be logged in my favorites for reference.

One question? The valve was made in two pieces to save machining, but have you had them separate, the valve head from the stem? regards

@572334 I have had no problems with the parts seperating in use. It would probably be better to make a one peice valve if it were a high performance engine though.

5:31 why did you use a DTI in a 3jaw? lol

[myfordboy]

@chevyvictor My 3 jaw is not that accurate. Tightening it with a different position gives different results.

Sir, I have been a fan for some time now and always enjoy your videos. I have a question for you: why did I see you use the knee instead of the quill when you were pecking?

[myfordboy]

@zapwatt My mill does not have a quill.It is a fixed head. The lever on the side is not a down feed but the speed control.

Are into forging as well? Because valves supposed to be one continuous fiber made from forging (for high loads on a real engine, I guess brazing holds for model engines).

Anyway, are you fond of blacksmithing?

why cant this guy be my next door neighbor?

Thanks for a great video,Its the way I am going to make my valves in the future ,Thanks a lot!!!!!

@titankron Thanks for the comment. The work is held in the vice which has been set parallel to the X axis. There is a V groove in the vice to ensure the work is parallel to the table. Hole is perfectly square and central .
