Cheers Nick, that might be an idea, I found them at Rimmers so if I can't work out a way of using solid head rivets I'll go for them.

The snap forms the head, the reaction block forms the tail so in this case you can use either a flat round steel punch as the snap and ideally a hammer head (not ideal) or something metallic and heavy.

 

Now depending on how tight the gap is and the type of rivet (the softer the better if not using a rivet gun and snap) you could use a tapered chisel to use as a reaction block if you can wedge something under it. I have done this in the past on smaller type rivets ie nothing bigger than 5/32nd.

 

A Cherry rivet will also seal the hole and all you need is a pair of rivet pliers. there are several types and grades, DO NOT use monel. These need a gun to put down properly. Aluminium ones can be put down with rivet pliers up to 5/32 with ease.

These are 1/8th pan head.

 

These are 5/32nd countersunk

Er... by rivet pliers do you mean a pop rivet gun?

 

 

etc...

Yes, i use a pair of MAC pliers at work and those bad boys can put down 3/16th Aluminium Cherry rivets. The only downside is at that size that are a pain to put down.

 

1/8th and 5/32nd go down really easy.

Ok, I'll look into cherry rivets,  The nearest I'm able to find on t't web right now is cherrymax rivets whatever they are.  Thanks for the links.

They will do the job. The biggest thing is knowing how thick the material is you are riveting together. This will then enable you to get the right length of rivet for the job. Most rivets are measured in 1/16ths length wise.

The ALU is 1.2mm. Two layers. What do you recommend Sonnik?

[Mini Manannán]

I've made the decision: http://www.ebay.co.uk/itm/221261435068  It'll be a snap to turn a snap up on the lathe, so long as they're not too hard they should a neat job.   Thanks all

You need to find out the spec of these. If their hardness are DD then you will not be able to form them. They need to be ideally AD. Soft enough to put down. DDs need to be heat treated to make them soft enough for use.

Ok, cheers, I'll send an ebay message, thanks again Neil.

Rivets arrived today.  Only ordered yesterday morning  He replied to an email (after they'd arrived) to say they are the soft type.  The Ramair ducting also arrived.  Thanks all for your inputs.  Onwards and upwards!
