Looks great Gus. I can't believe how quick it's coming together!

I can't help on the little hole though - I just glued my retainers with Loctite, but I may alter them, it would really help to be able to quickly assemble and disassemble the valves when you're trying to get the darn things to seal...

Good luck!

Hi Cogsy,

That was smart move.

Looks like I have to make a drill jig but I am worried about snapping the 1.5mm drill.Guess I have to clear chips repeatedly.
Will report and post successful jig drilling .
Will happen tomorrow.

10 pm here Tuesday 18 June.

Regards,

Gus Teng.
 
Gus, this is how I would drill the hole. This does not mean that it is the correct or only way but I have always had success this way.

Locate the position where you want to drill the hole in the valve stem. Put a 1mm centre drill in your chuck and first lightly mark the hole. Then drill gently with the centre drill. Replace the centre drill with a good 1.5mm drill and drill the hole. Use the highest speed.

Productive half morning, turned tappet valve no 2.
Make drilling jig.Drill the 1.5mm pin hole.Was nail biting. Valve stem must be loctited in to prevent movement. Ran drill at highest speed,took light jabs,retrieve to clear chips. Holes successfully drilled.Took precaution to avoid drill breakages with old/used drills and use new drill.
Install tappets on to valve manifold. Exhaust Pipe to 30 mins to do. Looks like bevel cut is a must to look like exhaust pipe as per print.
Thanks Guys for all the guidance and support.See fotos.
For tomorrow will work on the "carb". Now vacillitating-----to follow print or go my own way.

A few pictures back you're zoomed out a little where I can see the whole engine... that sparkplug, it's a boy!!!
 
Great work done again Gus. And you work so fast,unbelievable.
I'am still nailbiting to make another piece for my Hubbard engine. Some things will really not work.

Hi CS,

The big gear is my sensei(teacher) which will be the divider plate to cut the 25T
pinion. The gear cutters arrived and I am about to make a Dividing Head.
Sketches made.Reading material collected,read and comprehend.I have a
''KG'' Gear Master Catalogue which gives me all the pinion and gear data.
The Involute Gear Cutter sets,Module 0.8 and 1.0 cost me a bomb.
Will post DH fabrication and gear cutting. Will be a lot of fun.
Been a good week since last Saturday 15th completing the valve manifold with valve seats,tappet valves and carb.

See fotos.

The carb was mind racking and finger nail biting to make but turned out well.

Gus,

In post #65 I see a red wheel in the background... my curiosity gets me again, what is that?

I know, my curiosity, if I were a cat I'd be out of lives.

Hi jwcnc,

It's a mini tractor built in 2011. Run very well but the steering is still wacky.
The drive gear ratio is a bit high.Some time later when my gear cutting is up to
par,will cut a new set of gears to make it run slower.
See fotos. Red hind wheels came from Mamod,UK.The front wheels DIY.
Gas Burner also DIY. Underestimated the skill level required. Jigs and fixtures had to be made to make the difficult parts. My Silver Brazing skill not world best. The air-con plumbers made it so easy.
Overall dormant skills were resurrected and new skills picked up.
Been fun.

Hi Gus,
How are you coping with all that smoke blowing across the straits from Sumatra. Been watching the news.
From an Ex Expat Bule Gila .
The Webster is looking great.

Hi Goldflash,

Thanks for expressing concern to our welfare.
I stay indoor and wait for the PSI level to drop and right now at 7:15am local time,PSI(particle level indication) is about 300 and hazardous. A mini ioniser light given by a friend helps lower PSI in the bedroom. Will look for a bigger one for the living room.

The Indonesian President is responding and sending his men on site to fix it asap but the minister in charge is responding queerly,do nothing and expiring
garbage words and breathe.Just making a fool of himself.Our P.M.wisely chose not have a verbal war which makes it worse and get no where. This the worse occasion and was never this bad.
Conditions in Rhiau Province where burning took place,is way above hazardous. Airliners cannot land.Motorist cannot see beyond 100 meters.

South S.E. Malaysia is having it worst than us. So they will get vocal and very vociferous.:mad::mad::wall::wall:

As Gus,the conditon brings side benefits.With dry spell and inland sea water
receiving no rain means good fishing.Will post catch.

Dividing Head to cut pinion gear now W.I.P. Will post.


Regards,

Gus Teng.
 
Gus--I don't know your current situation re. smoke in the air, but reading about it fired off an old memory. When I was a kid back in the 1950's, growing up in "middle" Ontario, Canada there were really bad forest fires all across northern Ontario one summer. We didn't actually see the smoke, but we never had any bright sunshine all summer long. The smoke was so dense in the upper atmosphere it shut off a lot of the sunlight. I don't remember the smell nor irritation of smoke, but I do remember the summer with very little sunshine. Darn, hard to imagine that was half a century ago!!!
 
Hi Gus
I lived in Jakarta for about a year and Surabaya for about 6 months putting in CNG stations . we used to use the expression N.A.T.O a lot . ( No Action Talk Only)
Used to Bug out to Singapore to do a bit of shopping, bit of drinking, sometimes even did a bit of business.
There was one model airplane shop I used to go to there and they had the most amazing collection of engines on display.
Good Memories

There are now too many Aero model Hobby Shops. For your next trip try
Fook Hoi Building,there is 1/2 such shops. One shop sells mini lathe and mills
but he is too pricy. I can buy same cutting tools 1/2 his price.

Haze,

Some kind of goverment,the haze is now so bad in South-east Sumatra and nothing gets done.Palembang.Pekan Baru folks are choking,wheezing,coughing to death.
When the next tsunami happens in Sumatra,the Singapore goverment should do nothing. Food/medicine and rescue equipment were flown in by our Air Force and LSTs. Where were the Indonseian Air Force helicopters and Navy LSTs.All our good will forgotten. Contribution made to rebuild houses for Acheh went into local goverment official pockets.

A good number of vegetable farmers are growing vegetables and supplying Singapore on condition they use fertilisers and no forest burning. Their income is about S$800 per month 10 times local average.

Singapore is quielty giving financial help,agricultural training,market forecast
etc. These famers has never seen better days till few years ago.No money goes to so called local goverment agricultural departments.

Pork comes from Singapore financed pig farmers. Pig sheet becomes natural fertiliser for veggie farms and methane gas generators.

I find it hard to accept N A T O.
 
All activities to build "Webster" temporary stopped. Now building a cheapy,poor man's Dividing Head to cut the
25 tooth pinion gear for the 50 tooth timing gear train.
Please see my new thread--------Dividing Head.
 
Looking good Gus! I need to finish off my Webster sometime soon :)
