Machining a part that is larger than the bed

[Dropout]

Hi All

I know this is probably on the site somewhere, but I couldn't find the right combination of words in the search to find it.

I need to machine a 9 foot arc on a router with an 8 foot bed. How do I do it fixturing-wise, The software will let me split the part into sections, I just need a fool-proof way to move and re-set the part on the table.

What I do is pin everything with wooden dowell pins. Spoilboard to machine then blank to the spoilboard. I have to do stair stringers that are 18 to 22 feet long and I only have a 14 foot table. So I have to slide the work down to get it all. Sometimes I have to tab the part to the blank or use an onion skin of about 1/32 thickness then run through the wide belt sander to remove the part. If you have software and you can draw then it is easy to relocate parts to finish them. Every situation is different and the same method will not always work.

Depending on the width of your Machine you might be able to go corner to corner to get your 9 feet.
