F holes

Can anyone point me to a source of designs and templates for f-holes?

I am having a conversation with Bogdan Dobraszczyk who is building a mandolin for me, and I want to discuss ideas. I want to look at more modern styles, with cleaner lines. This would be for an A style instrument, not F style.

Many thanks.

I am not aware of any collection of templates, but why not just have a look at A mandolins by browsing pictures on the web and then having a go at designing your own, then you will have some real input into your new instrument? If it is a flat-top instrument with cross or ladder bracing you'll have to be aware of how the f-holes can affect the bracing pattern and positioning. It is easy to design a top and then find that the bracing is going across the f-holes - don't ask me why I know this! :cry:

A Google image search for "F holed mandolins" produces some interesting reults.

In designing them you should also think about whether you might need to get access through them at some time in the future. I remember a luthier friend of mine cursing me after he'd fitted a pair of K&K pickups into my GBOM; i.e. He couldn't get his fingers in to hold the pickups in place whilst the glue set.

Thank you both.

I've found inspiration, and my son will help me with a design with his CAD skills, so that a template can be cut. I've discussed dimensions etc with Bogdan, and I'm pleased to say that he seems to like the design idea.

It seems I shall have a new mandolin in the New Year - I'm beginning to get excited.

Thanks everyone.

An update: I trawled the internet for images, and then spoke to Bogdan. I got my son to design a template using his CAD software package, and sent this to Bogdan who who is getting the templates laser cut.

The design is a more modern look, based on one I found online. I am hoping that the finished instrument will look quite classy. I will post a photo when I have the new mandolin, in early 2018.

I was going to post an image of the template, but the board settings do not seem to permit this.

I finally worked out how to post an image, so here's the template (reduced size).
The mandolin should be ready soon, and I'll post a photo or two.Image
