Surveyor Posted August 29, 2021 Posted August 29, 2021 Just added another stove and decided to strip it down and get it sand blasted, I am going to remove the instruction labels which appear to be a cold rivet. Can some one advise if this assumption is correct and if so any source I think they are about 2 maybe 3 mm diameter. If not may use a pot rivet instead. Thanks in advance. Quote
Gordon_M Posted August 29, 2021 Posted August 29, 2021 Push rivets, they normally have a sort of dull self-tapping thread. There is a procedure to get these out, use a BLUNT chisel and tap the head sideways firmly, they will normally displace far enough for you to pull them out. Of course you have to do it carefully to avoid damage to the plate underneath. 1 Quote
Surveyor Posted August 29, 2021 Author Posted August 29, 2021 Gordon Many thanks, was thinking of the usual a drill but will try your suggestion when I can find a blunt chisel, have a fabricators not far from work they may have one. Will do some research on push rivit's, every day a school day and I do like this form of learning Quote
Gordon_M Posted August 29, 2021 Posted August 29, 2021 Sharp tap sideways will do it. Doesn't have to be a chisel, any solid metal that will transfer the tap without shearing the head off, just go carefully. These sort of rivets are normally used to attach plates to castings, liken engine block. Quote
Surveyor Posted August 29, 2021 Author Posted August 29, 2021 (edited) Thanks, I have plenty of screwdrivers that might work and as always will go carefully. Thinking out loud as I do, Think will try and knock the back where no plate. Will then know size of rivet needed and after treatment how to secure them Edited August 29, 2021 by Surveyor Quote
ruxy Posted August 29, 2021 Posted August 29, 2021 Push rivet ? Spline drive rivet ? Hardly - that seems thin sheet metal. What can be seen of the head on other side ? Probably just dome/button-head small soft iron rivets. 1 Quote

Surveyor Posted August 30, 2021 Author Posted August 30, 2021 (edited) The back of the rivet. Used a wire brush to try and show it a bit better Edited August 30, 2021 by Surveyor Quote
Gordon_M Posted August 30, 2021 Posted August 30, 2021 That's just a blind rivet that has been peened over I think. Should tap out with a fine on the back Quote

Gordon_M Posted August 30, 2021 Posted August 30, 2021 May be peened over on the back so you may have to grind or file a little. Quote
Surveyor Posted August 30, 2021 Author Posted August 30, 2021 Gordon Thanks heading out to sort it Quote
Surveyor Posted September 3, 2021 Author Posted September 3, 2021 Got them off now, the rivits are made of copper Quote
MatchFuzee Posted September 3, 2021 Posted September 3, 2021 Plenty of copper rivets on ebay, even some imperial sizes. Quote

Thanks, will have a look, the manufacturers label is covered in paint so not sure which size metric or imperial i need yet. The point you have made does bring another question to light at what point would the sizes be changed to metric? Quote

Sorry, no idea. The rivets maybe too distorted to measure but the size of the hole maybe measurable, and give you the size of the rivet.

Sorry it was a throw away type of question, yes the holes are measurable will do my usually trick of getting drill bits to see, provisionally I think about 2.5mm to 3mm. The guide is a great help as well Thanks Richard Quote
Surveyor Posted September 19, 2021 Author Posted September 19, 2021 For information 2.5mm flat head copper rivet Quote
7VHU Posted September 19, 2021 Posted September 19, 2021 That would be drive screws, but in this case you’re needing snap head rivets. guessing 3/32” dia. Ie round headed rivets. You’ll need a rivet snap too. Quote
