Hey Phil
Why the damn radio?
Joe

kiddin' ya, Joe. My radio is silent since I lost my XM. Plenty of brain work to do, don't need the dam distractions. Figgered the same for you with all that #crunchin' going on. Or are you multi-task talented?

Your port work leaves me searching for some reading material, on fuel atomization I suppose. Hope it shows results. Good luck again.

I believe fuel atomization is handled better in the carb. My ports are designed to transfer the charge to the cylinders as fast as possible (velocity). Surface finish inside the port may aid in the fuel atomization process. This subject is not my speciality. Fuel droplets are not good and fuel injection is not an alternative.

I saw a 1914/1915 transmission on eBay today if anybody needs one.

I saw that as well Chris. That tranny was offered in 1916 too. Any bets on what it will sell for?

Focus now on the Motor (engine)

The newly acquired !914 only cylinders have received some attention. First a crack was repaired using silver solder where the fuel primer cup was over tightened into the taper threaded hole. Next was a trip to see Mike Lynch, Mike has a motor machine shop with a Sunnen hone to run through the bore. Mike honed the bore size to nearly +.030" over until clean, this will now allow me to look into pistons. The cylinders were +.01" but had heavy rust damage inside the bore.

I located some new tooling for the shop. A 3 J collet chuck for the Okuma Lathe. This collet system is typically used on Hardinge Lathes and other small lathes. The 3 J collet has a capacity of around 1.625". Included with the collet chuck was an "emergency collet" this collet is a machinable collet so I bored it open to 1.5".

The 12" bar for the valve pockets divided into 5 equal lengths for five valve pockets. Turning one end of each of the 2.3 inch long slugs to a 1.5" diameter fits the collet. This collet will hold tight and eliminate the interference issues associated with the chuck jaws during the side window port milling operation.

Rods, flywheels, pinion, sprocket and crank shafts are curently being evaluated.

Joe, I'm going to have the same ordeal with my 1916 cylinders. Could you walk us through having pistons made for your cylinders. Thanks.

Joe, how is Mike Lynch? I haven;t seen hide nor hare of him in a couple years....was wondering if all was ok over there.

I am currently working with a piston mfg. I will up date this site as it pertains to the pistons as soon as the details are worth reporting perhaps next week. Pistons can be ordered in any size you desire, unusual ring sizes are not as easy to buy off the shelf.

Tom
Mike is fine other than a slight cold or something. A couple years ago he suffered the great loss of his father's passing. Mike and his father were commonly seen together during biking events. Mike may have loss his closest friend with the passing of his father. Tom you do know he is now a (happily) married man don't you?

Once upon a time I bought a Two Cam engine that had Knucklehead pistons in it.

All that Glitters is Gold

With the entire process sorted out it was time to produce the actual valve pockets from the golden copper nickel alloy. I have made a series of photos trying to capture shots of each tool (15 or 16) in this process. This photo session will test Cory's determinations here.

Currently the hex end of the valve pocket is set up in the Okuma and near ready to run. The last tool must be added to the set up and program. This will be a difficult operation without the right tool for the deep face groove. A Hogan Rotobroach (think hollow end mill) would work best for this operation. The tool will cut a groove next to the small valve guide diameter. The valve spring will set deep in this groove creating room for more spring travel.

I was told this material was "tuff to machine" so caution was incorporated in the process. It would appear my feeds and speeds worked just fine and machinability was not as difficult as anticipated. The difference being a good machine, good tools and plenty of patience.

Two of three brass bars arrived today for the intake manifold and nuts. Rob Forester is nearing completion on preparations for paint (priming and sanding) and probably will be working all weekend on my parts, Classic Plating (Redford Michigan) has all the nickel work in their possession finished and ready for pickup. Good things are happening.

Flat Head, Knuckle Head, Pan Head, Shovel Head, how about........... Copper Top? Omiting the nickel plating on these beauties may result in a nick name for this motor. In time perhaps they will turn green, my favorite color.

I got to the computer late tonight and found my mailbox piled up so we'll be a little short on pics. I'm sure we'll see more photos in the morning..........
