Don't give up mate.. I nearly did it a few times with mine I wrote the advert ready to sell then changed my mind. And I'm so glad I did now it's done I'm so proud of it and myself for finishing it .
You get to a point where you can't be arsed , all the work is ahitty welding , cleaning parts up spending money but then you come to a point where your bolting new parts on and it becomes a happy feeling knowing it's nearly done and you will find yourself wanting to get home from work and get on with it.
Keep going
