The New Look After Final Assembly

Finally, I managed to put back all the new modified parts as planned. I have done the run test and satisfied with the performance. Only that after every ride, need to check back the screws in case it may come loose.

Sorry, I did not have chance to take video on the run test. It was heavily raining so unable to include here.

May be in the next round. However, it works well so far.

You are almost there! I expect =your next post to be about this being a success.....and a video! Good job.

 

[landuse]

Well done!!!! I am glad you have everything back together again. You have come a long way to get this far. You must be proud of yourself. I always find that you get so much help on this forum.

I hope everything works like you hope it will

 

[Simon Thomas]

Thanks

Thanks to you and others as well. I received lots of helps and useful tips / guidance in this forum from keen and active members like you.

I should appear again in the next thread because yesterday I just took back my 6.5HP gasoline engine which had been used in my pump ski speed boat. I have replaced that 6.5HP with 7.5HP (which is more powerful and recently I participated in recent boat racing tournament).

I have 2 types of buggy that I want to try building in future. (i) Using chain and sprocket mechanism (ii) Using pully and belting mechanism.

These to be discussed in my next separate thread.

If you are having problems with fasteners loosening, perhaps you could locate some lock nuts, lock washers, or liquid thread locking compound such as LocTite #242.

You got a build thread on that boat anywhere?

Simon has a few pics of his boat in his profile album

Simon....I am sure that your future builds will go just as well as this one. You have learned a lot, and can use that knowledge for future builds

Good Suggestion

Thanks Toystory_4wd. You have provided me a way out to my problem and I should check with the hardware or any shop selling this stuff.

Hi DaiSan76,

Sorry I do not have that. You can check my album as proposed by Landuse to see the closer look. Actually, the boat is not my design therefore I feel not appropriate to elaborate it here in detail.

I included that story as part of the discussion because I have a unit of gasoline engine 6.5HP which I have reserved for next build. While looking for some ideas on how to start with the next build, I used it temporarily for my boat. Even the boat also was purchased from the boat maker who I know is a DIYer as well. They build their own boat from thin plywood and with modified 7.5HP gasoline engine, they could reach exteremely higher speed and can simply overtake 30-45HP conventional outboat engine. I have joined and witnessed them in several boat racing competition around here that is how I know this very well.

But my boat cannot reach that speed I mentioned above because it is slightly wider than the one they used in boat racing competition.

I intend to have a thread on this boat one day but cannot promise you. I do not know where I should park this thread as well and pretty sure this is not the right forum. When I do that, I should have my own design which I can feel proud sharing it with you and all. I prefer to have the design in fiberglass instead of thin plywood. Also instead of using propeller, I am not sure whether snowbile mechanism can be adopted here or not.

This will take time to consider because now I want to concentrate with my 2 buggy designs.


Landuse,

Yes of course. I am glad you were and will be one of my adviser later:biggrin5:

When you start building your boat, you could always start a thread in the Off Topic section. Anything goes there.

 

[DaiSan76]

Cool looking boat. I was interested in it because I am in the process of building a 9' tugboat, and I always thought making it inboard with a clone engine would be really cool.

Maybe I will take some pics of it next time it stops raining and make a build thread in off topic.

Thanks Landuse for suggestion. Then I have room to park this subject in the near future.

Cool Design Boat

You have a cool design as well. You can do the inboard engine with a clone engine. In the place where I am residing, people here use this clone engine (some use branded brand like honda, and some use the Chinese made engine). They use it in their personal boat for fishing or for river taxi (here so called "perahu tambang". You can find this via google search engine to see the look).

Although the gasoline engine has lower rpm compared to real outboard engine, one general advantage of using this inboard clone engine (without modification) according to the users and from their experience, it is economical in term of the fuel consumption.

You can do that. I am looking forward to discuss something like this with you in near future, including the fiberglass boat making beside the plywood and wooden boat making.

Purchase of design materials

This afternoon, I went to a metal shop that sells the construction materials as well. I made some purchase of these stuffs for my need. This includes hollow section pipe which I need for my next build.

 

[landuse]

I am not sure if you have said.....but what are you planning on building next?

 

[Simon Thomas]

I intend to design a buggy again with the same size of wheel with gasoline engine 6.5HP. I am still not sure whether I need to equip it with the absorber or not because I never did this in the past.

I am also browsing this forum to look for a model.

 

[Doc Sprocket]

You don't necessarily "need" to include suspension (springs, shock absorbers etc) in your design. However- if you intend to build a buggy in the traditional sense of an off-road vehicle capable of travelling over rough terrain. At low speed on pavement or relatively smooth gravel or dirt, a vehicle with no suspension will perform, but arguably not very well. When the terrain gets rough and/or speed increases, performance goes from poor to very uncomfortable, and even dangerous. Control over a wheeled vehicle boils down to traction, and a suspension system is vital in keeping all wheels firmly planted on the terrain, thus affording that traction.

Do you NEED to? Perhaps not. Should you? Yes- if you plan on building and driving a "buggy".

Thanks. A good tips from you. In my case, I do not travel on a terrain (if so, it is very rare) and does not require high speed. Basically, a simple design without suspension is good enough. I put this as priority for the time being.

Hey Simon....in the first pic you posted of the metal shop, it looks like you might have some axle material there, or is that the hollow pipe that you spoke of?

Hollow Pipes

Hey Simon....in the first pic you posted of the metal shop, it looks like you might have some axle material there, or is that the hollow pipe that you spoke of?

Those are the hollow square and round pipes. I bought 5 pieces yesterday of all sorts of shape which I feel needed for my next build. I haven't decided the model I yet, however I think I better have all my materials ready. This would motivate me to continue the works as planned.

After all, should I have the excess later, I can sell them scrap here . The only thing I am particular about this hollow pipe is thickness. I use the arc welding theferore I need a suitable thickness. I ever wrongly purchased the materials, and they ended up as my keyboard stand / support .
