Portable Jump Ramp Project

[Stephen]

Hi guys

As a DT project for my school I am designing and making a portable jump ramp for use with RC cars (I was thinking around 1/10th scale buggies and SCTs primarily), and I am currently at the research stage. I would greatly appreciate it if you could take the time to fill in this short survey, so as to give me some quantitative data to work from.

Thanks in advance

So..... why are there questions about pricing if its a "school project"? If your looking for feed back about designing and selling a ramp setup, then just say it. Kinda shady for a first post.

I have to agree with that assessment.

Sorry for any misunderstanding. We have to design it with a client in mind, as if it is going to be brought to market. So we have to do all the relevant market research as well as material testing and analysis of existing products. We then have to use this information in the design and development process to show that we considered other options and decided against them. The course is specifically A2 Resistant Materials, in the UK.

This is the specification of the course. The unit I am currently on is Unit 4 - Commercial Design. Pages 113 and onwards.

I hope this clears every thing up.

I've finished making the ramp, and brought my 1/10th SCT into school to test it last week. I didn't go easy on it, and I can't see any damage other than a few scuffs in the paintwork.

Here are few photos and a quick video I threw together showing my ramp in use.

The upper section of the frame can be pinned in six different positions, including fully extended and fully retracted. The legs are telescopic, with the inside sections being held in place with thumb screws. The slats that form the ramp surface are connected by three strips of webbing, and are held onto the frame by velcro (bloody strong stuff).

The frame is constructed from laminated plywood, the legs and joints are aluminium and the slats are plywood, covered in grip tape.

I'd be very interested to hear your comments, and any ways in which you think I could improve the design.

Dang bro,that is one nice,high quality looking ramp. I've built a couple of all wooden ramps but they are a bit heavy and harder to move around and take places with me. Looks like you have portability nicely covered too. Great Work!

Very Nice!

Wow, now that is a sweet ramp! Great job!

Thanks for the comments guys! I'm hoping to make a proper video of it next week. I'll keep you updated if I do.

I think that's first rate! Nice job.
