pfenlon Posted February 25, 2021 Report Share Posted February 25, 2021 With grateful thanks to a well known Forumite, the job is now done, just a couple of rivnuts fitted and the plate installed. Looks a treat too. Quote Link to post Share on other sites
ianc Posted February 26, 2021 Report Share Posted February 26, 2021 (edited) I hope that this is a resin-filled coil as an oil-filled coil might suffer local overheating if some of the windings at the upper part of the can become partly exposed in the horizontal position. This has been explained in another Forum topic: "Coil Position". Ian Cornish Edited February 26, 2021 by ianc Quote Link to post Share on other sites
Z320 Posted February 26, 2021 Report Share Posted February 26, 2021 (edited) This threaded rivets are cool, I would also use them on my TR if I would find a set UNF/UNC threaded.... And steel, not aluminium Edited February 26, 2021 by Z320 Quote Link to post Share on other sites

stuart Posted February 26, 2021 Report Share Posted February 26, 2021 FWIW The steel ones that are anything over 1/4" UNF are very difficult to pull tight, I use aluminium ones for a variety of things and they are perfectly adequate and pull up nice and tight.

Hi Pete, the oil filling is nigh on 100% if there is an air bubble it will be very small - don;t panic.

Stuart. +1 - I tried pulling down a 6mm Stainless rivnut with the basic pliers. I had to cobble together a G clamp and other bits strapped across the handle of the pliers to get it to collapse. They are seriously tough. Roger Quote Link to post Share on other sites

If its oil filled you will hear the liquid. There is always an air bubble to allow for expansion when hot. Roger is right though - it should be nearly full and probably won't care at all about being horizontal. Unless you coil was specifically provided with instructions from the maker not to do so, and even though the internet is full of advice, I believe this is mainly just myth and that it will be fine. The coil is wound with the lower voltage primary winding on the outside and is spaced from the can wall - you can see below the diameter is a fair bit smaller than the can. There is plenty of room for a small bubble in the gap and the winding should still remain submerged and in any case, the oil will be sloshing around as you drive.

stuart Posted February 26, 2021 Report Share Posted February 26, 2021 Not come across one, theyre usually similar to pop riveters. Stuart. Quote Link to post Share on other sites

RogerH Posted February 26, 2021 Report Share Posted February 26, 2021 Hi Waldi, thanks for that. I decided to google what is out there. Somewhere between £70 - £150. Quite a few but they look iffy. Some very nice ones made by Avdel for....................................wait for it................................................. £1500 (fifteen HUNDRED pounds) Obviously professional aerospace.

BlueTR3A-5EKT Posted February 26, 2021 Report Share Posted February 26, 2021 No Riv-Nut tool? Use RawlNuts They hold the TR6 screen washer bottle in place OK https://www.toolfastdirect.co.uk/acatalog/Rawlnuts.html Quote Link to post Share on other sites
harlequin Posted February 26, 2021 Report Share Posted February 26, 2021 When I did the Riv-nuts in the floor for the gearbox tunnel on my TR3 I made up a tool using an angle grinder spanner and some washers, nuts and a bolt. It worked OK for the few nuts that I had to fit and I couldn't justify the cost of a reasonable AF sized tool George Quote Link to post Share on other sites

Waldi Posted February 27, 2021 Report Share Posted February 27, 2021 Hi Stuart, It states it can do M10, I guess that’s for aluminium, not CS. The company, HBM is know for relatively cheap but good products. They do direct import themselves. I have ordered many items from them, most are good for our hobby. I assume you may want something more “upmarket” Stay safe. Waldi Quote Link to post Share on other sites

Ver y helpful over the phone and next day delivery. I wanted to fit one to my new CTM TR5 chassis in the rear diff bridge for an additional exhaust hanger. Couldn't just drill a hole and fix a bolt and nut through because CTM had boxed in this originally flimsy U shaped section with a bottom plate for extra stiffness. I installed it succesfully with a nut and long set screw, 1 spanner and a socket to pull it up. Dave McD Quote Link to post Share on other sites
