Today 2 layers of epoxy were sprayed on all of the sandblasted parts. Black epoxy for all the parts that will be matte black and white epoxy for all the parts that will be matte white. I was able to help with sanding some of the parts and mixing the white epoxy. But the spraying was ofcourse done by my sister. It really looks very nice already, would already love to take it all home.
I'm really curious now how it'll look like when the actual spraycoats are on there but I have to be patient for that. Next Saturday all of the black parts will probably be done though. The white parts will come after that and are also some more work.
Tonight I went to the sandblaster. All parts of the frame are done and all look the same now. I already left them all at the company where my sister works so she can start spraying it all. We put all parts together there, already looks pretty nice. First a layer of epoxy will come on it all, then all the spray coats.
The spraying will probably take a few weeks since everything will have to be done inbetween work or outside of working hours and it's quite a lot of work. But at least I know for sure that the result will be very nice. The coming weeks I do still have some things to do, first I can finally start cleaning the whole workspace and prepare everything for when the sprayed parts will come back.

Good news, I finally have everything done for sandblasting. This weekend I worked really hard to get everything to fit and also rounded off all corners and sharp edges.
First some pictures with everything in, the mounting points still weren't made to size here and still no corners rounded off.
And here with everything out, looks pretty nice. And it's also very strong, I'm really happy that I decided to go with 3 mm steel instead of aluminium.
Then I took everything apart again and placed all parts that have to be sandblasted together. There are quite a few parts.
So these are also the last pictures with that ugly glossy white and all those bare spots. Hopefully I can go the sandblaster this coming week already, I'll keep you updated.
Meanwhile I also had some new bushings made of the material POM. The small ones are all for the front swingarms en the 2 big ones for the rear swingarm. These are replacements for the bad rubber bushings (front swingarms) and needle bearings (rear swingarm). POM is very suitable for this, it's very wear resistant and smooth. Many quad bike riders use this material as replacement and are very happy with it. I still don't know myself since I can't place them yet till everything is sprayed.
I also got some new bearings for the front wheels and rear axle of the brand SKF. These will last much longer than the original Chinese ones that were in there.
In the bearing house I also had a slight modification made. The speed sensor of Trail Tech is quite a bit smaller than the original one and also has a different thread (3/8 inch). To be able to mount the sensor in the same spot a bushing was placed in there, works perfectly.
That was it again, hopefully another update soon with a sandblasted frame.

The less good news first. I wanted to remove the bearings and axle from the bearing house so I can soon place much better bearings of the brand SKF in here instead of the Chinese bearings. This just didn't go so well on one side, a piece of the bearing house broke off and there's a small crack as well. So I can't use this one anymore.
But I did get everything out so at least I know how everything fits together now.
Here's one reason already why I don't want to use these Chinese bearings. Just look at the difference between the 2 bearings, the one on the left has no grease at all in there while these are still new closed bearings. But they're bad quality anyway, these bearings break very quickly. Especially that one without any grease.
Meanwhile I already got a new bearing house. There were also bearings in this already but everything went well removing them this time.
And then the good news. All mounting points for on the frame and the battery boxes are finally done. Was quite a bit of work, especially since I had to make these to size using only a bench vice, hammer and file. But they can all hopefully get welded within a few days now.
The ones for the smallest battery box up front were the hardest because they needed a few corners and a part that's skewed. But they turned out pretty good, definately strong enough for the 2 batteries that are going in there.
I also made the holes in the front fender already with mounting points for the charge plate. Ofcourse I used rivet nuts for this again.
Hopefully another update soon once everything's welded.

Much has happened again this week. I completely dismantled the quad bike so that all parts of the frame can be sprayed soon. Was pretty fun since I've literally had each and every part of the quad bike in my hands, I know exactly how it all fits together now. I've also come across certain things that I'll be replacing right away with better alternatives, especially the bearings and the bushings in the front swingarms and rear swingarm.
I was able to remove the whole brake system without even having to disconnect a single brake line.
And this is what the quad bike looks like right now, only parts everywhere.
I already removed the bushings in all of the swingarms. These are all still new bushings but they don't really look like that. These Chinese bushings also don't really work like rubber bushings are supposed to work, they're actually hinging in the swingarm itself instead of in the rubber so it's steel on steel. This will wear out very quickly, especially since there was no grease at all anywhere. The plan is to place POM bushings in here, works much better and lasts much longer too.
I also got some new parts again. These are all the wires that I'll need to make the whole wire harness.
There's also a handle switch and 2 mounting points for the mirrors. And also a seperate killswitch with cord so the high voltage will be disabled if I leave the quad bike in any way.
But the most important is that the gauge and charge plate are done and thanks to Geraets Metaalbewerking they turned out very nicely again. Everything fits perfectly again as well. I just can't really show yet how it'll all be mounted exactly since the quad bike is dismantled but to give an idea I've made a few pictures.
I'm working on making all of the mounting points to size now, these might get welded to the frame this coming week then.
