IMHO the fist step of building yourself a helicopter would be to have some parachuting lessons... ::)

chrispare, got your bearing housing here here! Very nice! Updating: Steam Chest Cover: complete Cylinders: need polishing Pistons: Need to drill for gudgeon pin and mill the inside corners for con rod clearance Gudgeon Pins: 0% (doesn't take a lot of time to make) Working hard on them this...

Got the parts from Dalem9, Joe D and Warrantor. VERY nice parts from you guys! My congrats! =) Sorry for the delay about my parts, but I've been very busy in the past month with final tests... I'm almost done here! Running as fast as I can! ;)

Warranator Thanks a lot! :D Pascal That's OK to me if you take a little longer to ship all together: it will save you on shipping costs I'm trying my best to meet the deadline but with so many tests at the end of this semester I may not be able to finish in november. If so, sure I'll finish...

A heavy flywheel helps the engine to run smooth, and try to use ball bearings everywhere you can! :D

Path, can you e-mail me the new drawings? Thanks a lot!

I was planning to use cast iron for the pistons, the same i used for the liners. Is there any problem using the same material for both? If so, I think I could use aluminum or brass (maybe fosforous bronze too). For the wrist pin, is it ok if i use shafts scavenged from old printers? They would...

I have: 10 Steam chest cover - 100% complete 15 Cylinder Liners - 100% complete 15 Cylinders - 60% complete 15 Pistons - 20% complete (production halted for plan review)

Just got a few parts done: 10 Steam chest cover 15 Cylinder Liners Will post pics soon! Next: 15 Cylinders and 15 Pistons ;D

In part #1 Steam Chest Cover, the 1/4" - 36TPI really need to be this thread? It's been a pain to find this tap here! I could use MF6 (6mm x 0,5mm) or (6mm x 0,75mm) or even 1/4" - 28TPI What do you guys think? And what finish do you want in them? Sandblasted or mirror polished? ;D

I would like the solidworks files too! ;) The pdf drawings would be better for everyone to follow the exact plans, as they're easy to view, print and download.

Now THAT'S a neat stuff! Karma point for this!

November 30th is fine for me! But I'll do my best to send the parts as soon as possible!

I'm OK with making 5 sets of #9 pistons, #7 liners and #6 cylinders (total of 15 of each part) plus #1 Steam chest cover (10 parts) Path is right about taking it more slowly now, so I'll wait for this final plans to start making chips ;D The only thing I'll start right now is look for the...

If nobody else shows up to join this TB, I could do the remaining set of #6 cylinder #7 liners #9 pistons. So Path would do one set (11 of each part) and I would the other two sets (22 of each part). I'm SO excited to start this Team Build! How is the metric/imperial decision going?

Hi Pat, I can help you a little with solidworks. PM me with anything you want! Since I'm doing parts 20 and 21, I can drill the parts for either imperial or metric (they don't have any threads on them). So feel free to draw the plans with the best choice for the others to build ( We don't want a...

Could the cylinder liners be made with trunk shocks tube? They're pretty smoth ans polished inside, and the one I have here are 16mm inside. I believe that would be possible to get more of the same dimension.

Can I be in charge of making parts #1 steam chest cover #20 steam chest? If you guys think #1 and #20 is too little job for one person, I can make more parts, no problem!

Although we use metric in Brazil, I have no problem converting inches to mm and making parts as close as possible to inches dimmensions! ;) What I think it is important is to decide one plan and stick with it, no matter if imperial or metric. Also I vote for Potty too! A very nice engine!

I would like to join too, if possible! ;D
