I'm a bit more partial to steam engines, but open to all designs.

Either of the Elmer's would be good, I'm leaning towards the radial.

Me too! would love to have me a radial.

Flame lickers are a tough road to go guys.

I've built just almost every engine in Elmer's book and they've all run.

I've built 6 flame lickers.
One runs and one tries to run every now and then.
As for the other 4, they're still works in progress.... 3 years and counting....

OK here is quick photo. I scrounged through the enco spring assortment pile and looks like I hit pay dirt . I also put a couple of the thumb nuts in the photo. bought a pack of 25 so there are plenty for every one to get one and I have leftovers for other projects. Still need to make the studs.

Rick is right about the flame lickers.

How about this one? I alwayse thought it would be fun. The cam would be a breeze on a CNC.

I built a Comber (Elmer #46) engine a number of years ago, about 20 I think. It's one everyone wants to see run. It runs well and there is enough mass is the rotating cylinder that it does not really care if there is a flywheel or not. I helped a friend program his CNC tocut the cam rings for two more. With parametric programing it's only about a dozen or so lines of code. Mine is kind of a "plain Jane" type and building another one, maybe slightly dressed up would be fun.

Looks nice Tin. I made a QCTP mount for my Proxxon IB/E rotary tool. Once you have it you find all sorts of ways of using it.

I would also rather go steam, and being about 2/3 thru the Chuck's Horizontal Single, agree it might be a little much for our 2nd build. :-\
I like the steam rotary (Comber) idea, as the oddball steam engines are always fun to watch, Elmer also has # 5 the geared steam engine that is pretty cool, it is fascinating to watch run.
I would just want to make sure there were enough non-cnc parts for those of us manual operators to do our fair share. ;D

Just my $0.02

Bret,
All of Elmer's engines can be built without CNC. Probably most parts are as easy to do manual as CNC. The Comber cam ring is one of the few exceptions. While it can be built on manual machines, as Elmer did, it would certainly be easier on CNC.

Hey guys if we could build a GM 3400 for a '96 Lumina APV I would be more than happy to recieve the extra engine. :big: :big: :big:
Motor blew in my van :'( :'(

Ouch! Sorry to hear that Tim.

Nice Tin!

Looking good. I am getting very excited about this engine!


On a side note to Gail... Your signature, I try to live up to the expectations of 2 dogs and 1 cat :big:

I do like the comber (#46). Do we have someone with CNC to cut the cams? Or is anyone good enough to do it manually? I know I am not

Eric

 

[GailInNM]

I can cut the cams if desired.

Hey Bob, I just start by Eyeballing it. Then move it back and forth and up and down until it start cutting good. Quick and dirty) It took me longer to type this than to center my drill.

I set my mill up so i could tap these holes. This picture is fairly self explanatory. I'm holding a tiny vice in my 4" milling vice. The small one has some tiny V guouves that are handy. I used the center in the chuck to locate the hole. I dipped the tap into the oil before each hole. Then cleaned the chips off the tap before the next tap.

I like these spiral flute taps because the chips come up out of the hole. here is a great picture of what I'm talking about. I have 20 of them tapped now. I'll try to finish them after work tomorrow. Lots of tapping going on here) Tap, tap, tap.

Better get to bed, Work starts at 5 am.

I think the Comber should be it. There is almost no info on it on the internet. This would be a great unusual engine for us. A video would be neat.

I am in agreement. All else?

Sign me up guys!

[kustomkb]

I like it too, I couldn't find any video or much else either. Maybe we will be the first.
I can do the cnc work or any manual work.
