Hi Gus,
It's coming along great! Now that you have the biggest parts made it should be smooth sailing.

the drilling jig is a great idea! I was hoping I was accurately repeating enough with my DRO to match my front cover to my crank case on the one I'm building right now, but with a jig to do both, I wouldn't have to hope.

I've discovered with cast iron, you can reduce some of the dust by taking as heavy of a cut as your lathe will tolerate for the roughing passes. You still have to deal with the dust for the finishing passes, but at least the roughing passes seem to make big chips that fall straight down instead of flying all over the shop. The mask is a good idea regardless.

Hi Gbritnell,

Thanks for the support.

When the Star Fruit tree is in season,I could harvest the fruits but the mango tree is too faraway.


Hi Chris,
Good idea but the mini lathe is 1/4 hp and it is doing its very best and any deeper and faster feed, will stall and belt slips. The mini lathe is again stretched to its very limits. Just wish I could buy a bigger lathe but my three open sided balcony garden machine has very limited space. Sigh. When I get tired/stressed,I would turn around and enjoy the greenery. The awning is but oversized but it keeps Gus dry and comfortable whenever it rains.

Day Fourteen.
The OuterHead Blanks cut. The Makita BandSaw saved Gus from the very punishing hard labour of manual hacksawing 2 1/2'' x 2 1/2 x 1'' thick Aluminm Bar. With the DIY DRO I was able to mill to exact width. The Starrett Digital Gage came in very handy to mark out and check dimension of the OuterHeads.
Both blanks took 3 hours to mill and another two hours to mark out the holes and drill and mount one O/H.
Both Heads have is a long way off to complete with so many details and parts as a sub-assembly.
Took a risk and deviated to using M4 fasteners for the cylinder mounting to crankcase and outerhead to cylinder.
The cooling fins will be done soon as the 1/8'' slitting saw comes in from Arceurotrade UK. Mini mill collet:wall: won't take 1/8'' EndMills.

that's a very pleasant shop you have there!

Gus--It is -25C outside with 16" of snow. I too envy you your "pleasant" workshop. I don't particularly mind the winters here, but by this time of year I am getting awfully tired of it, and we still have about 6 weeks to go before it really starts to let go.---Brian

Dat 15.
Was a hot and humid day and work proceed as usual.Took my sweet time to drill/tap and mount second. Drill and reamed the valve holes and rocker arm support holes. Took great care with these holes any goofs will render Heads as scrap or oversized paper weight.
The inclined holes for spark plug and the counterboring will be tough on Gus and the machine tools. Counterborer will be DIY/custom made and heat treated. Some one gave me a 20 mm o.d. hi-tensile fastener. Hopefully it will respond to heat treatment. Backup will be case hardening to make it hard enough to cut aluminum and at last last thru counterboring 2 holes.

Tomorrow is fishing and no machining for two blessed days.

Hi Gus

It's coming along great, keep taking it steady Gus and enjoy the fishing this weekend, will be in Singapore next week, will try again to hook up with you but probably will be to busy.

Hi Dave,

On some Saturdays and Sundays,you may see a white colour 28 ' Albin at anchor 300---500 meters away from Loyang Marine Base/pier. Thats Gus fishing..

 

[digiex-chris]

Hi Gus,

Great work, keep it up!

the counterbore doesn't need to be particularly hard to cut aluminum, two holes should be easy. A high tensile bolt should be perfect. If you can avoid annealing in order to cut it, it you probably wouldn't need to do anything to it. I wouldn't expect it to do anything when using it to counterbore steel or cast iron, but I've done similar things with un-hardened steel when cutting one or two holes in aluminum. Heck, if it dulls, sharpen it again.

Hi Gus, it's coming along well. You could always make a split bush to hold smaller cutters, or make up an adaptor that will hold it.

Am glad ,I took a break from the machineshop. Here is foto of my best fishing session in ages. It was strike and at every bait dropped in. Hit three hot spots and it was non-stop bite. After five fish,we moved on to next spot to prevent overfishing. Five fishos each took home 4 fish.

Come Monday,Gus very much refreshed and game to hit the machineshop again.

Is the spotted one a puffer fish?

Hi BarnBikes,

Its a local good eating Coral Cod Fish. Here in Singapore we have very poisonous Puffer Fish. Puffer Fish aka Fugu are butchered by highly trained Specialist Japanese Chefs in Japan.Despite all precautions, one or two partakers die each year.
Was in Nagoya and my Japanese daughter-in-law wanted to buy us FuGu dinner which is very expensive. I had to politely turn down offer.

I am crazy about Sushi and Sashimi and Japanese food but FuGu is a no no.

Hi Gus I Wish I could fish I don't know why but if I drop a hook in the water the fish curl up and die of laughter, it's been that way all of my life. it's not that I don't try ??? I have two rods on the boat. one for dangling and one for trolling but never any luck.
You are surging ahead with that v twin while I am struggling to finish my engine just getting all the material and tools is a bind in Sicily.
Struggling on Brian.

19 O.D. CounterBore done using HiTensile fastener bar. Bored to 2--3 mm depth and goes dull. Will wait for
Case Hardening Compound to arrive. CB tooth seems a bit shallow. But trial cut on a softer aluminum bar was beyond 3 mm. Suspect I may have to anneal outerhead. Expert advice is humbly seeked.

 

[digiex-chris]

Don't forget to keep your rpm much lower than you would with high speed steel. If you provide a flute per tooth, even a straight slot, it may go deeper. It might have been just recutting its own chips because they couldn't get out of the way of the cutting edge. If you have 5-10 degrees relief there. Then I think that's all the tooth you need.

Love you'r work Gus.

Nothing beats a good feed of fish

Started fishing seriously and persistently and most days come back with nothing since 1980s. Got serious,Bought my first boat but fishing did not improve. Was a very steep learning curve. Best tidal days,ebb tide and rising and find the spots that will produce fish.Catches did improve but very erratic. Alex Chee came along and gave some and in fact lotsa spots. Whenever he was on board ,we get big fish. His spot on anchoring on the structure was good. Wasn't until yesterday when I finally realised the peculiarity of his spots------You must use sinker locate knock on the rocky structure to attract the fish. If there are good size fish,they will hit instantaneously. Can be line breakers or line spoolers.
One big problem coming,the fishy mates were jokingly taking me to task for not taking them to such productive spots prior to today. If Gus was ever consistently producing fish,he would have become a most sought after Fishy Captain/Guide. Alex's spots are very small---------size of coffee table. Very hard to locate and anchor spot on.When water is bad or feeding hour not on,they won't bite. Fresh Bait is a must. Ha ha ha.
