Simple & cheap clamping of workpieces

Postby GrblGru » Thu Sep 24, 2015 6:09 pm

In this forum I've seen a lot of solution for clamping the workpiece on the wasteboard. But I'm missing a very simple and also cheap variant, that I've used for my little DIY milling machine. I've drilled 6mm holes in my board and have plugged plastic dowels in each hole. This allows the using of simple wood screws.

Ingenious!

May have to try this instead of T-nuts in my next wasteboard. Certainly far more affordable.

Great idea & it's not much of an issue if you run a bit into one.

Could one get a nylon screw into one of these (and back out)?

That’s one of the nice things about the T-nuts I’ve been using is that I can put a nylon machine screw into them and not worry about hitting it (actually was cutting them off for the paths of the Studley calipers).

Thanks. I don't know, because I've never try it.
But at first I've tried normal metal screws with less pitch than the wood screws. To fix the workpiece you need a lot of revolutions. Because I'm lazy I prefer the wood screws. :)

Interesting solution. But how often can you insert/remove screws before the insert is stripped? They're cheap to replace, anyway.

Nylon screws is a great idea! I've been using brass screws in my fixtures because I figure hitting one of those won't cause any issues.

On the other hand, I did run an 1/8" end mill through the mild steel plate on my vise at rapid with no apparent damage... viewtopic.php?f=7&t=4445

Thanks. They're also less expensive than brass.

I had to plan the paths so that I'd be pretty much cutting off most of one screw on my locking register calipers:

I also used aluminum screws other places where the risk was lower --- probably those would be fine for the plastic insets

Anyone hear of using plastic nails with a nail gun?
I have used regular brads with a nail gun and it doesn't rip up the waste board like a screw does.
It is quick in and out.
Obviously it works for soft wood but not when I am milling plexiglass :)
