Please help!!!!!hsc major work

[johnlimburg]

hello everyone, my year 12 major work is due in 8 weeks and im stuffed because ive left it to late and my prototypes just wouldnt work as i tried steam bending (which wasnt great) and lamiation or cold bending with a mould. However i was wondering if one kind individual would like to design me a male and female mould which would bend a basic "C" shape. Like the link shown below.

You must open the pic full size (maximize) to see the picture in full.

Can you provide more details of what you're trying to achieve? What is the project you're building? Size, materials etc?

You might find some people here willing to help, but it does seem to be very late to be doing this for this year's HSC.

well it is 1300x600x500 coffee table which is going to made from thin plywood and after all of my testing i figured from several tests that steam bending was not going to work for what i wanted and with my lamination of plywood i used the mold in the link below. However it didnt work that well (air bubbles). I want the finished product to be around 20mm.

Yes. Im an idiot. It is pretty late

Any advice would be appreciated.

this is the design. Pretty basic

Your best approach is to provide a lamination ether by steam bending or cold bending the top and bottom layers. Then use solid timber for the fill including the curve.
What is the inside curve radius/diameter?
I doubt plywood is the best timber to use for your lamination due to the way plywood it is constructed.

If laminating around the frame you've built is going to take too long, or you just can't get it to work, you might consider changing the method to use kerf-bending. In your project log, you should describe your attempts at laminating and the reasons for switching direction. Here's a good article on the process:

Girl at my uni made a coffee table a similar design to this... (a 'C' shape)

have you any idea what technique she used

About 6 months ago I made a set of shelves in 20mm European Beech which incorporate a 90 degree bend made by coopering the timber on a mitre saw. It was pretty easy to do & wouldn't be too hard to do 180 degrees.

With your limited time, I would be heading in this direction.

Good luck.

Sorry mate, but I don't really want to just 'give away' all the research she has done.

But what I would do, because you only have 8 weeks left, is just make the female part of the mould, using the male part you already have....

This isn't what the girl at my uni did...but we have access to a CNC which helps a lot.

Looks good so far mate, keep at it.
