Finished modeling up engine, now time to build.

[doc1955]

Thanks Dean!
I know it seems like that can't be.
an-noid I remember some inspectors of my past that were exactly that. :big:

Times have changed when I started out in this trade there were no such thing as dro's and Cadillac gauges it was read the veneer scale same thing with calipers dial calipers were just the new craze back then. I started out in the machine shop when I was 19 years old and some of the things seem like yesterday.
One of the most remember able projects I worked on was the x29 tail wing there were 2 built and now one is in the Smithsonian the other I believe Nasa has.
Anyway I didn't realize just how much I missed making chips until I started this project I'm sure glad I found this website it spurred me on to finally purchase a mill and a lathe and start making chips again after thinking of doing it for the past 10 years.

Wow Doc, I just found your thread & caught up with how far you've come with the project. This is a jewel!

When I read the 1st few posts I thought, here we go again, another pro showing off his CAD/CAM & CNC skills. Your CAD work is fantastic but I'm really luv'n all of your manual setups, fixtures and jigs. Definitely an education for me and a leap forward in learning different ways to solve machining problems.

Thank you, thank you, thank you! ;D

If I ever come across that way I don't mean to. I'm far from being an expert at CAD/CAM. I don't own a cnc so every thing I'm doing is conventional mill and lathe.
I'd like to have a cnc but right now I'm doing it conventionaly.

 

[DICKEYBIRD]

I don't own a cnc so every thing I'm doing is conventional mill and lathe.

Exactly! That's why the intricate work and methods you're showing in this thread are so valuable. It gives us manual machine owners hope and the motivation needed to get on with difficult projects.

Wow, it's really taking shape and looking good now Doc.

really very good doc

it's the same engine that I have under my name here, but your seems to take shape in a better way: great work :bow:

 

[Deanofid]

What's up, Doc? Haven't seen anything new from you for... a whole day!

Dean

 

[doc1955]

Oh I'm still here still have a nasty head cold. I'm awaiting a shipment of brass from Enco should arrive tomorrow.
I needed some brass rod to complete my build I was mistaken when I thought I had some of the stock on hand. So I broke down and ordered some 6' lengths of 3/16, 1/4, 5/16 & 3/8 diameters I had larger stock but didn't want to turn down large stuff to make the small link pins I need.
Head colds really suck my eyes feel like they are toughing my glasses :big: sinus pressure.

 

[Deanofid]

Oh man.. Sorry to hear you've got the crud, Doc.
A cold didn't use to bother me when I was still living like a young person, but as I get a little older,
seems to take forever to get cured up.

Hope you're feeling better soon.

Dean

 

[doc1955]

Thanks Dean same here colds hardly ever slowed me down until a few years back I ended up with pneumonia now they seem to be twice as bad. I've been going to work but its a struggle plus the snow shoveling isn't helping much. I've been to pooped to go out to the shop in the evenings.
I read and look at the board a lot and there sure are a lot of talented members with all the beautiful workmanship being shown.

I like your website you have some really nice work shown very very nice! It looks like you have been very busy at the hobby shop I like your flywheel on your low temp engine. I've built one but was never successful in getting it to run matter fact I have 3 as when I was building them I made three at a time and no runners. I set them on the shelf for awhile then go back and tinker awhile give up and put them back on the shelve. I originally built them back before I left the shop environment about 10 years ago.
I'm hoping to get out into the shop on Saturday for a while if I start feeling better starting to get anxious on finishing these engines.

I've never had pneumonia myself but my wife started getting it in the fall of every year for about 5 years. Then the doc gave her a "pneumonia shot" I guess it's like a flu shot. Hasn't had it again, since then. (3 years ago)

I've been copy/paste ing your build. Get well soon.

[cfellows]

Some beautiful work going into that engine. I'm enjoying the build.

.......Very nice. Lots of small hand machined parts. I appreciate as a sophomore modeller here witnessing the patients and crafting of such engines. :bow: Dave.

 

[doc1955]

Thanks Dave.
I didn't get much done this week end with not feeling up to par and having to shove show.
Did get some of the small link pins done I'll post pics when I get a little more done.
This darn snow has kept me busy shoveling both here and my father-in-laws plus had to shovel off the roofs which is always fun. Anyway I hope to get some stuff done after work this week.
I'm anxious to get it done and move on to some thing else. I want to make a small cdi system for my IC engines that will be the next project.

 

[doc1955]

Well I machined last of the link shafts it was a bit of a chalange since I decided to use some 17-4 which was pre heat treated.

I machined some blanks with .150 extra material on the ends to allow me to put in some center hole to turn between centers plus milled down the .062 thickness of blank I left the .125 width I needed at .250. I then created a center with a drive slot in it which worked very well will be saved for future small parts turning.

Started turning here.

Close to done.

My little center drive dog combo worked very well.

After turned I went to mill and milled the length and width and drilled holes one more piece done complete.

I then went back and put the set screw holes in my fly wheels I set them at a 10 degree angle.
It gave me a chance to use a angle tool I created a long time back.
It consists 5 rows of holes radially drilled 5 degrees between holes and each row advanced 1 degree.
It is possible to set you parallels in your vise at any angle you need.

After that then I started with all the link pins and spacers have most completed.
I have 2 parts left to make before first full assembly and first run.
The two parts are a link clevis simple part and the valve link bell crank.
So I'm getting close to first run hope to be this comming weekend.


PS Here is my favorite little edge finder 25 years old and still finds the edge right on.

 

[Ken Bartlett]

Very nice project so far. And the angle setting plate you have pictured is a great ideal. Ill add it to my growing list of tooling to make.

 

[doc1955]

Thanks Ken.
By the way just wanted to mention the red on the tool post holder is Red Dykem I noticed it looked like I had a big boo boo but not so.
I'm partial to red dykem I feel it goes on thinner than the blue stuff anyway just wanted to make that clear not a boo boo. :big:

 

[Deanofid]

Doc, this build has been great to follow along. This last post with the three shop tools you show us make it all the better. The small lathe dog and your edge finder are nifty. That angle plate is super.
Thanks a lot for the pics!

Dean

 

[doc1955]

Thanks Dean.
I hope to into the shop again on Saturday and hope to have a runner by Sunday. Then after I get them running tear down and do some sand blasting and painting before final assembly.
My next prodject will be buiding a ignition box for my IC engines so I can have one system to share with all my motors instead of one on each plus I want a small compact system what I use now is just too big.

 

[doc1955]

Well things didn't work out last weekend and so far this weekend haven't been out in the shop much.
Going to try and get out there this afternoon to try and get some done. Starting to get anxious to get them running.


This week some time a friend of mine is getting a new lathe delivered. I'm going give him a hand at getting it unloaded and set up.
