I've built this machine 100 different times in my head!!!

Thanks, I figured that was how. Just wanted to check there wasn't some cunning way I hadn't thought of!

Think I'm going to be changing my design yet again!!

Adil / andy / dean got to say cheers to you fellas! started drawing up a gantry based on this L layout and intuition is saying this is soooo much better.

You're welcome buddy, I'm also at a stage where I'm very pleased with my design, finally stopped stressing over it and started to get it built.

One more question if I may - what profile brand are you planning on using?

**Iwant1** · 24-10-2012

I'll be buying from KJN KJN - Suppliers or Aluminium Profile and Accessories since they do a 45x90 profile unlike Value Frame whose closest is 40x80 profile. I went with bigger is better, also from reviews I've seen on here about their good service and accurate cuts, I'm sold.

Don't for get to order all the extra connecting elements like T nuts and screws when you place the order with your chosen supplier. Also if you go with profile rails rather than supported rails you need to check the maximum socket head screw that will fit in the rail pocket, as you will have to get appropriate T nuts. For the profile rails I have, I found an M6 thread will fit but its head is fractionally too big, so had to use M5. For connecting ali extrusion profile with other I'll be using M6 Screws and nuts.

Hope it helps, Adil

A couple of quick queries please Adil...

Does the fit of the T-Nuts in the Slots allow for a wee bit of sideways adjustment, or can you achieve this by using the M5 socket-screws in your rails?

I'm wondering whether it's best to go for high-tensile screws/bolts or whether A2 stainless is good enough....

Also where peeps have found a good place to source socket-head-screws? Did you just get them off eBay?

Screw fix is always a good place to start?

I use the local fasteners shop (Charnwood Fasteners). Perhaps search for places that sell fasteners nearby as they should be much cheaper than eBay or Screw-fix.
