Rudys Radial 5

[stevehuckss396]

Looking good Dave.

Is there a reason why the end of one of those rods is different from the others?

That rod must butt into the center of the crank disk to lock it in and create the master rod. Radial has to have a master rod.

Looking good! I struggle to make 1 cyl and piston match up. Can't imagine doing 10 of them.

Got somemore done on the Radial 5 engines im making. I got some .125 brass tube from the hobby store to make the transfer tubes. I bent them with a 90 degree on one end then cut them to length. I had a fixture to hold the tubes for soldering. I used that to mark for length. After I got all 10 tubes bent it was time to solder them. Did I mention I hate soldering.

Here is what I started out with

I put the fixture in a small vise and held it at an angle to be able the get the torch on the bottom of the fixture

I then mounted the small brass foot that will attach to the valve body. Its held with 2 2-52 SHCS.

I Then put the transfer tube and head on the fixture after applying flux on both. The brass block on the fixture is to make sure the tube is straight during soldering

Here is a picture after soldering

And the final picture is of the 30 pieces made into 10

Did I mention I hate soldering.

Well, for a guy who hates it, you've done a nice neat job... I like the jig, clever work :bow:

Cheers, Joe

Rudy did a great job when he drew the plans for this engine he includes all the fixtures to build the engine.

 

[dreeves]

Well Its been 1 year since I started this Thread. I have been building the two engines for friends as time allows. I have then at about 90 percent done.

I spent some time in the shop today and got the cranks done.

I then drilled and taped the holes in the rear of the valve body to hold it to the stand.

Im still waiting on the base parts which are being cut at a local school. I also need to cut the valve's which are a real pain to do. I need to order some .875 Dia steel rod to make them.

 

[dreeves]

Its Alive well engine A is. :big: I finished the crank pins and put everything together the first time without oil and thats when there was a problem :wall:. I took everthing back apart and this time put oil on everthing. The next set of pictures are the second time back together.

Well everything spins smooth so down the stairs I went. So here is Engine A which is going to my friend BOB W.
I Hope to get both complete within the few weeks. I will post more pictures of the parts when I break it down to clean the 2 engines to clean them.

That has better sound than some of the others I've heard. Did you do anything different?

Looks nice!

Very nice Dreeves :bow: :bow: :bow: Any plans for a prop? If so will you make or buy it?

[zeeprogrammer]

Looks and sounds great Dave.
You've been busy since I saw you.

 

[dreeves]

Thanks for the positive comments. I need them after a long build.

Chuck, I did not do anything diffrent but I agree the engine does sound better that the first one I built.

Swilliams, I will be using A 3 bladed plastic prop on both engines.

Thanks Eric its been awhile.

 

[cfellows]

Real nice finish on those heads. How did you get them cleaned up so nice? Cleaning up soldered brass is not one of my strong suits.

Chuck

 

[dreeves]

Chuck, I used a dremal tool with a soft cloth and polish. They still need some work.

Got some more work done. I made a visit to the Williamson Free School where I was having some parts made for the engine.


Here are the parts I picked up

Here are the new toys the school just got 2 haas mill centers

Here is a shot of the rest of the shop

Sure wish I had that shop as my own

And here are 2 of the parts on the base

I hope to get more done on Saturday Till than

 

[dreeves]

Got some more work done today on the Radial 5 engine. I made some parts for the base. Im not sure if I like it you what do you think?

Hi,
The parts looks very nice, they mate very well with the engine.
The legs had rubber in the middle or are they painted black?
