I've been inspired by your wonderful work Tony. I finally got around to doing something with the box of stock bar I bought from Hemingway Kits about 8 months ago which has sat in the corner of my garage ever since. I'll post some pictures when I get around to taking them. Keep up the excellent work.

I've attached a couple of pictures of the timing gear housing. I scrapped two before I got it right!

Hey Tony,

If my math is correct you have the balance of the cylinders complete. Awaiting pics...

Rob, Jeff,
Thanks guys! Had to take a day or two off. I will resume tonight.

Nice looking gears. Did you make them? What was the problem with the first gear case?

[Rob.Barrett]

You can get the gears as gear blanks, they already have the teeth and the bore, I did the lightening holes and profiling on the face. I also have to cut a keyway in the smaller gear. The first gear case I scrapped after a having a numerically dyslexic moment and the second I snapped a 1mm drill off in a breather hole.

Looking forward to seeing the rest of the cylinders Tony, what bit were you going to tackle next?

 

[cobra428]

Rob.Barrett,
I think the front and rear cases, then the crank and rods and finish up the bottom.

One more cyl. I'm going to try and get another done tonight. I can't put them next to each other yet (except for the middle pairs) without more operations. I have to put flats where they meet.

Here goes

I needed somethings from Enco and I said you could use a set of riffler files. Well I looked at MSC $425 a set Rof}

Enco had a set for $7. What the heck, I'll take a chance. Ran them across some A2 steel. They work and still
have teeth to cut again. I can buy a lot of $7 sets for $425. And how often do you use them.

Thanks for the update! I've been checking 3 time a day.

 

[cobra428]

Hey Steve,
Thanks for the interest. I got my eye on your straight 8.
Got another cyl knocked off tonight.....3 more to go! Then it's put flats so that they fit next to each other.

Gee Tony, all that work making nice round fins, then you have to cut some of it off?
I object!

; )

Dean

 

[slick95]

Looking good Tony I keep checking your progress too...

Jeff

 

[cobra428]

Thanks Guys,
Dean, sorry to say they need flats to fit in the block. Before I do that I have to de-burr the fins. The old eye balls didn't pick up on the burrs, the camera sure did. I'm going to use a triangle file and turn the cyl in the lathe to clean them up.

Jeff, I slowed a little. I bought another Kool Mist for the lathe. I liked it so much on the mill and it was a pain to move back and forth. So, I was bizzy running air over and hidding hoses behind walls. I got tired of tripping over them.

Tony,

It is amazing the flaws, small marks, etc. that show up in the pictures. A look at George B's close up photos and you see nothing but perfection. Some day I'll learn how to get that finish using files, emery, riflers,etc. I keep watching close in hopes of catching the techniques.

Keep up the great work buddy...

Jeff, I know GB's stuff.....amazing. One day I'll learn how!

Tony

One day I'll learn how!

Photoshop may be easier. :big:

Nothing to show much of tonight. 1-1/2 cyl. done. I picked up a collet set from Grizz. It arrived yesterday. MT3 and EO?? collets (I forgot what the tech service guy said they where). I bought the full set. MT3 will fit in the spindle of my small lathe (HF 8x12) and with an adapter MT3-4 will fit my Grizz 10x22. The only thing...I taught I had an 4-3 sleeve...I didn't. Today I ordered that and a 3-2 sleeve. It's an extension but it will allow me to use it in my rotary table which is MT2. I'll have to build a special jack to support it. This small work is screaming for collets.
In the mean time after I finish up the cyl's I am contemplating how I will bore the front and back of the crankcases to accept the nose and gear box at the rear as well as the center crank support web and cap. Mill? 4jaw on the lathe? Mill makes the set up easier but....I don't know which way to go right now :noidea:
Then I remembered that I had bought about 2 yrs ago a electroless nickel plating kit from Caswell (for the radial's intake and exh pipes). Why not plate the cyl's?? I tried calling them but it was after 4 and they close at 4. Tomorrow I'll find out about the shelf life on the chem's (I never open the bottles) and if it will be good for bore plating.

Collet set. This is a pic of the half set. I will make a draw bar set up for it so it won't come loose.

Thanks

Tony
