Useless blade adapters.

[caveman]

My scroll saw came with useless, non pin end blade clamping devices. Basically the blade goes through a small hole in the device and then you have to try to clamp it between two allen screws. Obviously, when you turn one of the screws to tighten them, the blade twists and even snaps. I have filed the ends of the allen screws flat but it makes no difference, the blade still twists.
There is not a lot of room between the bottom location point for the adapter, plenty at the top.
I have looked all over the place to find a suitable clamp but so far have drawn a blank.
Can anybody suggest one please? The locating pin is 12mm wide.

Would these replace the shiny metal part on your saw?

Rather than an adapter, just change the clamp.

I looked at those Naz but can't work out how they attach to the saw arms. There are no clamps on the saw arms as you can see in the photos, just a hook and two pin-blade locations.

Um, I wonder, if I remove the current blade attachment system, those clamps might just fit in their place. I need to check the threads!

You have an Allen screw that holds your ''shiny metal springy bit;; onto the end of the arm.

See this pic - they fitted those clamps inside the shiny part, utilising the same screw.

Replace the round bushing in your blade clamp with those new ones.

Yes thanks, that was how I thought they fitted but the bolts look much bigger than the ones holding my mounts on - these are only 3mm allen screws, theirs liik to be around 5mm.
Any way, having seen the Axminster ones I have decided to make my own from a bit of aluminium bar. Hope the aluminium wont wear too quickly at the clamp area?

Thanks for this link NazNomad - I checked these clamps out but they wouldn't fit, however they gave me a template so I bought a bit of aluminium bar, 1cm X 10cm and manufactured my own clamps to fit my saw.

Bit rough but they work a treat!

They look ace. Nice job.

I can now use the very thin, spiral blades for cutting out the gears, much easier than turning the piece all the time

Those clamps don't look too rough to me mate, AND they do the job. What more do you want? Well done.

I just need to countersink the nuts so I don't need to use a spanner when tightening the clamp with the hex bolt! Tomorrow is another day
