Thread: More book stands

Good on you Jacko, hope you will have some photos for us. What timber are we talking here?

Well done Jacko!!

Probably will use some river redgum that I have as I know that I can steam bend rather easily, being air dried and of a colour acceptable to the client.

Like it. Nice lines - top curve a Fibonacci sequence?

Certainly look interesting. The design reminds me of stain glass arched windows.

Not a Fibonacci sequence, just a simple arc. The intent was indeed to create a Gothic Window" impression. Just hope that reality will match the design.

Nice design Jacko.

I thought it looked slightly ecclesiastical. Looking forward to seeing photos of the finished article.

Thought a few may be interested in the construction phase of the stand.
The first part is likely to be the most difficult, namely the base.
It is comprised of 4 laminations each 7.5 mm thick. These were steam bent to the 250 mm radius using a form and compression strap. The timber as predicted is Forest red gum chosen because of color and knowledge that it was air dried. Laminations showed about 10% spring back
The lams were then glued up using epoxy (more later) and the final product had less than 1% spring back which was acceptable. I left one lam short tom create the "mortice" that will be needed to attach the verticals.
A few notes on steam bending etc that I have found.
1) Thicker laminations appear to show less spring back than thin.
2) Avoid flat sawn for quarter sawn
3) A heat gun on the outside of the compression strap can assist during the bending process.
4) I have found that Techniglue epoxy has the best characteristics being very brittle, thus little creep. This makes it better than West Systems which seems to retain some flexibility which is fine in e.g. boat construction. (also goes off faster) Another good one is Urea Formaldehyde with 10% PVA added
5) It is a good idea to freshly rough sand lams just before glue up for the best adhesion
6) Laminations tend to "cup" across the width. Using clamping cauls with centre relief tends to put pressure on the (more visible) outside edges and pull things flat.

Rippa another Wip nice work Jacko and well done on the last one.

River Red Gum looks nice neighbour has just moved to Mildura

Excellent info in that post Jacko!!!

Have a greenie!

This should be interesting.

Looking good Jacko. Love the timber colour.

I really like the look of this Jacko.

What will the rods be, maybe stainless?

Currently being turned up. Probably cost me half my profit!!!
