>>-Lam stack calculator tool------>

Buemaker · January 30, 2012, 04:07:00 PM

I need some help. When I click on the link it opens up in Exel, but from there I cannot figure it out. Where I put the cursor it is usually an arrow , but now there is a cross and I don't know what to do. Will somebody take me through it? Thank you. Bue--.

When you open it up, there should be 3 colored cells, with numbers in them (C7,C8,C9). All you need to do is click the cells and input your numbers. The answer is automatic when you hit enter.

Thanks Brad!

Has anyone developed a similar tool for all-wood laminated bows?

bjansen · January 31, 2012, 07:59:00 PM

It should work exactly the same....same concept

Thanks Brad and after trying the program out I now understand your response!

I know that this is an old thread, but it is referenced in the stickie at the top of the page, so thought I'd post here.

The files seem to have 'disappeared'. I get error messages that the files are not available when clicked on. If anyone still has these files, I'd love to get a copy.

Thank you.

Make that two of us who would like the calculator. The response I get for either of the links is:

Unfortunetly, even I get the same message. I have tried a couple times to re-load the file but image linky simply doesnt work.

I am happy to send it to anyone if you send me an email, and better yet if anyone else knows how to re-post the link in another format I would be happy to send you the file or try it myself.

Thanks

Imagelinky is not working, it says upload error but gives a url anyway which does not work as we found out.

The following at file dropper works but who knows for how long. Enjoy.

XLXS VERSION

XLS (OLDER) VERSION

Best regards,

Perfect. It worked great. Thank you Pago.

Thanks, but thank Brad Jansen. I received the file from him awhile back after requesting it.

Thanks Brad.

KenH · January 15, 2014, 08:20:00 PM

Thanx Pago and Brad both!

I must of missed it but what length bow is this set up for.This is awesome just what I was looking for. Thank-you

bjansen · January 15, 2014, 09:28:00 PM

This is not for a specific length or style, but more of a tool if you had made one bow and want to build another (same model/style) but a different draw weight.

jess stuart · January 15, 2014, 10:13:00 PM

It works very well, I use all the time. Brad is due a big thanks for making it available.

KenH · January 16, 2014, 07:53:00 AM

The calculator has nothing to do with length or shape of a bow.

The idea is that if you build one bow of a given shape and stack thickness, and it comes out X pounds draw; if you double the stack thickness on a second bow of the same shape, the draw weight of the new bow will increase 8 fold.

The calculator works great -- it confirmed my S.W.A.G. when working the calculation backwards. A prototype Scythian replica I made was 'way out of my desired draw weight. I wanted 30# but got in excess of 75#.

I chose the lam stack for the Mark II prototype based on my Scientific Wild Ass Guess of that 'rule of thumb' backwards. I'll be doing the final glue up n the next few days so we'll see what draw weight I actually get.
