Yeap, you always said it, so no one can say they did not know jajaja! But I really encourage you to try to make it run. What more do you need?? just a good variable power suply!! If you had the hability to design and build that engine, dont stop at the last stage!!! Can you post info on...

easy, because you already have 50% of the work when making a radial, and they are easily available and more or less cheap. Most of the people that want to make a radial, dont want to fly it, they just make it for fun and to make it run. And if the total cost is low even if the size is low, no...

stevehuckss396 sent me the plans he had. I have to say I am unsure if the engine will run. Steve him self has not started the engine. I have seen several faults, and I am unsure it can run..... I would not recomend anyone spending money building this engine, until someone has proven it runs

Have you read all the posts on this thread??? Please read them https://www.homemodelenginemachinist.com/threads/098-v-twin-using-2-cox-049-cylinder-assemblies.22013/post-248594 I managed that a company made an order of taps very cheap

Just a few images on the engine my friend is building

I am glad I can help others with just some work. Looks interesting that some companies are a little bit business short minded What cox proyect do you have in mind?

I am starting with a friend a cox 9 radial. We have already bought 10 new piston/head assemblies, and 10 glow plug head adapters. I had a long time search for the correct cox tap with the 17/32-40 thread, and was astonished with the quotations I received from several companies, up to $200...

Hello all Could someone post images on the hardware conversion of the F1?? I would like to see how the new stepper motors are attached. paco

Hello, A good friend has acquired a good old Emco F1 unit, with revolving turret. He would like to make it to work with Mach 3 software. He is not English fluent so here I am helping him with some English words ;-) The issue, he and I dont know much about conversions and options available...

I have found 2 USA companies selling the tap for arround $50 per unit. Once I have confirmed the price, I will post it so every one can benefit.

Hello all I got last year a bottle of flux for silver soldering. Have read in this forum that the paste has a shelf life, and wanted to clarify if this is the powder that comes in the bottle, or the paste result of mixing the powder with water and a drop of detergent. I am specially...

Hello Norman, Where have I said that I have adopted the silver brazing system to make repairs on my car? No, lets see, I added the link on my site, because I found the video very useful to understand the procedure of making a good silver welding. Also because " maybe some parts" in a...

Hello all, I enclose a link to my blog where I have a video explaining silver soldering that might help many http://www.ahsprite-mk3-restoration.blogspot.com.es/2012/11/six-steps-of-successful-brazing.html

Newman tools sells it for $140, not cheap! http://www.newmantools.com/price/taps_ns_pr.html But what I see is that when ordering 6 units, the price drops to $50 which is more convenient. For you north americans, it should be easy to join 6 and buy the tap cheaply! Is there any interest to...

Hello all: Many have build very pretty inline engines. The easy ones are made with cox pistons and heads, as they are cheap and readly available. But the problem with the cox, is you end up with a small engine. I was thinking that during the 80's, many many comertial engines like Enya...
