Re: Finally went through with it

I promise you I'll post one up as soon as I get it runnig (which could still take some time BTW :wink: )

Meanwhile, I finished the fenders for the rear wheels. In the picture you can also see the cut tires and milled down cooling fins.

Re: Finally went through with it

Small update: - made some fuel tanks (still have to think of a way to mount them) - fitted smaller sparkplugs (I had to, because with the original sparkplugs the engine was too wide to be legal in the class) - started shaving off some material to save weight. Removed some material in the rear axle (...

Re: Finally went through with it

Ok, this thing has been sitting on the backburner for way too long (lots of other things going on) I picked up where I left it a couple of weeks ago and I thought I'd show you guys the progress I've made so far: New rear axle: http://img163.imageshack.us/img163/3452/p1060446.jpg http://img204.images...

Re: Finally went through with it

Well, it's been a while, but finally here's an update on the project. The first thing that had to be done was to fire up the engine, and see what we're dealing with. So I started out with making a solid stand for it: http://lh6.google.nl/Micropuller/R2ro5Dnf41I/AAAAAAAAAE8/Iq6UW0Rkr3U/P1000362.jpg?i...

Re: Finally went through with it

Well, the first chips have been made! Normally we use 1:8 scale buggy diffs, with a kind of planetary gear reduction in the rear wheels, but due to the low Rpm of this engine that's not an option. Running a buggy diff without the panetary gears on an engine like this is out of the question, so I nee...

Finally went through with it

After weeks of deliberation, I finally went ahead and started what will probably be my last big project for a while. I have been wanting to try and build the most overpowered puller possible, within the limits for size and weight in our club. Why did it take so long? Well, let's say that the engines...

Onboard camera

I've recently purchased a very small (USB) camera: http://www.pkracing.nl/diversen/f%3Bycamd.jpg Yesterday we tested some newly built tractors and decided to mount the camera on the weightbox of our sled. Here's the results (and yes, the tractors got out of control, it seems thei're just a bit overp...

The first thing you need to know is the difference between soldering / brazing and welding. When you're welding, you actually are melting the material you want to join together. Whilst the material is melted, you add some of the same material as a filler. When soldering or brazing, the base material...

New project, again not my puller, but a lot of parts made by me. Some of you might remember the crossbox / supercharger unit I made. I never got around to building a puller around it, so I gave it to another member of our club to try it on his twin 1.08. Problem was, he didn't have the equipment to ...

I've used one as an onboard RPM counter. Compared to a hand-held unt it was quite accurate. When using it as a speedmeter, you have to take into account tire-wear (as the tires get smaller, your speed drops) and tire slippage though.

First try wasn't a big succes. Here's what happened after about 10ft: http://img442.imageshack.us/img442/9135/img7727fp0.jpg Tried again with glassfibre reinforced gears on the engines and a steel gear in the center. The sound of this thing (especially indoors) is incredible! You can actually feel t...

The gears are bought, but were modified to attach them to the clutchbells. They're made out of POM (Acetal Polyoxymethylene Copolymer)

No they don't. Except for the engines, everything you see in the picture is custom made.
