My Design

[Simon Thomas]

Thanks Landuse. This really really helps.

I need to check with the motorbike shop. At this moment, I know the shop has smallest 14T and biggest 47T. If put into calculation, I should get a better ratio.

(47/14) * (47/14) = 11.27

Well, let's see how much I can do with this later.

I found the smallest is 13T. Biggest still the same 47T.

This ratio will be a lot better than what you have in my opinion. You will be a bit slower, but you will save your clutch from wearing out

Thanks Landuse for your suggestion.

I am done with my 1st buggy design and have no intention to upgrade it. I enjoy riding it here in remote area where none of the people have done this so far.

Whereby for my 2nd buggy design, I don't think I want to continue with it because I could not find the gearing parts. The gasoline engine still can be used in my boat.

Keep us updated. If you use it in your boat, why don't you start a build thread about that. I am sure there will be a lot of people interested in putting an engine inboard a boat.

Metal Cutting Tool

I saw this in one construction area where the contractor cutting the metal with cooking gas and oxygen gas. Cooking gas to replace the acetylene gas. Of course the gases go through the regulators. I also saw the same method used in the scrap metal site using the cooking oil to substitute the acetylene gas.

I have a few questions with regards to this method:
1. Is it something common in other places using the same way? 2. How good is using this method?
3. How thick the metal can be cut with this method?
4. Is it safe?

If this works, I plan to buy the same equipment for me to cut the metal instead of grinder. Want to hear your comment.

I don't have any experience with this, so I am going to leave it for someone else to answer you

I used to work next to an engineering shop which only ever used LPG (cooking gas) for cutting. It's cheaper, more easily accessible & does pretty much the same job.

However, like running a car on LPG, it uses more than the standard gas (acetylene).

Hi Landuse,

Speaking of my gasoline engine, there will be boat racing or regatta at my place here at early of July 2012. I may be participating by using the gasoline engine in my boat. However, I am not going to ride the boat because I am 80+ kg of weight. I am too heavy for sport like this thus I am going to find someone else to ride it with lighter weight probably ~65kg. With this weight on boat, the speed of my boat is faster than 15HP common outboat engine. That is the ideal weight for this kind of sport. I will try to update on this in future. FYI, the Thais also racing with the gasoline engine, however their engine sit on the boat rear, whereby ours is mounted in the belly of the boat. Only I do not know which one is faster if the two setups are put into racing bacause never done.

FYI, I am quiet now from updating my thread because I am concentrating on my solar panel project. This is something that I do now which I have 10W solar panel, the solar controller to charge the battery, 12V 80AH car battery and 500W inverter to convert 12V to 220V.

In my village where I come from (when I write to you, I am in town), we still do not have the 24 hours electricity. The nearest town is 3 hours drive from my village. That may take may be 10 years to come to have 24 hours electricity to reach us supplied by the government (I am kidding!!) So, we rely on the diesel gasoline engine and the electricity is only available at night 7pm - 12midnight. Hopefully, having the solar panel may help in situation like this.

So far, I am pleased with this little project and with the simple unit setup I have, I can run 2 units of 5W energy saver bulb and 2 units of USB fan at night from 7pm -7am the next day. This is a start which I intend to explore more if I have more budget. We in Malaysia are blessed with sunlight from 7am - 7pm, so why not make use of it. I do not know whether we can share something like this here because this is out of the main story (go-kart) discussed here.

Hi Fabroman,

Surprisingly this is not only seen in my place.

Thanks for visiting my thread and thanks for your comments as well. FYI, I have been to Sydney in 2005 and stayed at Anzac Street. Was there in 2 weeks. The last day there, I walked from Anzac Road to the main city. I could not remember how long I took to walk that day but enjoyed the view along the way. I have seen the Harbour Bridge, Opera House and Hyde Park.

I have been to Canberra and New Parliament House as well which I walked on the grass on top of the New Parliament House.

Honestly speaking, I like Sydney and the beaches. Hope to be there again in future.

Once again, thanks for your comments.

I'm glad you enjoyed our city enough to want to return.

It used to take me about 30 minutes to walk from the city to Moore Park (you would have passed it on you walk) but, I would guess, it would've taken you longer by taking in the sites along the way; Darlinghurst is a rather "clolurful" area.

I live in the south western suburbs of Sydney but went to high school in the city so I got to know my way around pretty well. Did you visit Centerpoint Tower while you were here? (it's Sydney's answer to Seattle's Space Needle)

Hi Simon, glad to see you back

I am a novice when it comes to anything electrical, or with circuit boards, so I will not be able to help with your solar project.

It will be interesting to see how you mount your engine in your boat. When you do it I would be interested to see some pictures. I always think that you would get leaks easily by mounting the engine inboard.

It really sucks that you only have electricity in the evening. I also have to commend you for posting so much if you can only do it in town. Thank you for taking the time to keep us updated

Hi Fabroman,

I could have missed that place in last trip to Sydney:biggrin5:. It was a short trip and nothing much could be done at that time.

Hopefully in next trip, I should spend more time there in order to see more things as well.

regards,

Simon

Hi Landuse,

My answer to your question:
"It will be interesting to see how you mount your engine in your boat. When you do it I would be interested to see some pictures. I always think that you would get leaks easily by mounting the engine inboard".

The anwer is there is no leak if the engine is mounted properly. FYI, it is very common seeing the sampan and the boat here mounting the engine inboard and no leak if installed by the experienced and expert boat man. It is not leak that they could travel with their boat regularly for daily and weekly. There is some leak but normally not from the engine mounting part. It is usually caused by the old wooden material and some punctured by floating objects which hit their boat when travelling at high speed.

I should share some photos from the regatta later which is scheduled on 7 July 2012, as announced by the organizers.

 

[Simon Thomas]

Landuse,

I try to get some pictures for you on mounting the engine on boat.

Before that, this is how the gasoline engine (normally used for go kart or buggy), used in their sampan. It has very important use that this gasoline engine can be used as alternative to push their big sampan and transport motorbike to cross the river.

 

[Simon Thomas]

This is how they mount the engine on their racing boat, so called here "pump ski boat" here. Next week is the regatta day. With 7.5 hp Chinese made gasoline engine used on their boat, you will be surprised that they can simply overtake 40 hp real outboat engine here. Very fast, but this small single rider boat is only can take one person at a time.

They can mount the engine in their boat without any leak. Probably the leak can be from other part of the boat belly like punctured when hitting floating object, but not likely the engine base.

So if you already fed-up using you gasoline engine in your go kart, you still can keep it to be used in your boat. That's what I want to share here.

Hope this is useful info for those interested to diversify the use of their gasoline engine.

Thanks Simon! We dont have any boat racing near me, but it looks like fun. Thanks for the pics
