Hello All, Been wondering if there's a great/strong way to bond extrusion together. Ofcoarse drilling some holes through and screwing them together is most common, but I'm wondering if you can bond them together, then add hardware to make an even stronger joint. Any Ideas?! Thanks in advance - Tony.
That is how I did it. The printed parts held them in place them I drilled through and bolted them together.
Unfortunately, I don't have nor have access to a 3d Printer...Next project after completing my Large CNC router Thanks for the info
You might look into marine grade aluminum epoxies. You'll want to scuff the anodizing to get a better grip and use temporary backer plates to hold things into proper alignment.
I'll look into the marine grade aluminum epoxies. I plan on placing two CBeams back to back to form 80x80 extrusions. If they are not stiff enough, I'll armour plate them
My machine has two 2080 sections bonded together for the x-beam just rubber toughened CA glue, has held up for 2 years and going, z crashes and all. Just lightly scuffed with 400 grit and cleaned, there is so much surface area it's not a difficult bond. Hard part was making sure to get the alignment right first try, you get one shot, I used tape as a hinge and a flat surface.
Never heard of 'rubber toughened CA glue'...I'll look into it and give it a try. Thanks abunch for the info!!
Just one option, epoxy would be more forgiving as you can use slower cure time to get the position just right. Cheers Gary
