RogerH Posted October 5 Report Share Posted October 5 (edited) Hi Folks, Today I was trying to re-fit my NS front wing (TR4A) . The three screws on the 'A' post have been a challenge. So my grey cells started creating (usually very messy) Would it not be beneficial to fit studs in the screw holes and then only nuts would be required in the 'A' post confined space OR - If the screws that go into these holes had a plain shank to help align then life may be easier. Option 'B' will be tried tomorrow. Roger Edited October 5 by RogerH more text added Quote Link to post Share on other sites
stuart Posted October 5 Report Share Posted October 5 If you use "Self starting" i.e. pointy bolts then its easier to get them to line up. Stuart. Quote Link to post Share on other sites
RogerH Posted October 5 Author Report Share Posted October 5 Hi Stuart, I had thought of that (HU706) but why do it the easy way Roger Quote Link to post Share on other sites
BlueTR3A-5EKT Posted October 5 Report Share Posted October 5 Cone or dog pointed screws are what you need to use. HU 706P was originally specified. Or HU706D if you can find them In stainless and quantities under 1 million. To convert the screws you have simply fit a nut, hold nut and bolt hexagons in the lathe chuck and turn the threaded end to the shape you fancy. The dog pointed and drilled screws I conververted from regulator flange headed ones to fit the rear hub to the Girling axle. Quote Link to post Share on other sites
RogerH Posted October 5 Author Report Share Posted October 5 Hi Pete, the screws with the little nose are what I had created in my mind. Tomorrow -- reality. Roger Quote Link to post Share on other sites
Ian Vincent Posted October 5 Report Share Posted October 5 (edited) I have a device for chamfering the end of bolts. It fits in my electric drill. Means that I can buy stainless bolts and sharpen them to make fitting easier.

rcreweread Posted October 5 Report Share Posted October 5 I have also used the bolt deburring tool which Ian mentions, like this: https://www.ebay.co.uk/itm/326294334430?_skw=deburring+tool&epid=18032391897&itmmeta=01J9EZ6X67ZWV6EC780HF8929R&hash=item4bf8a86bde:g:GHIAAOSw4YBnAVVt&itmprp= Cheers Rich C-R Quote Link to post Share on other sites
BRENDA1 Posted October 5 Report Share Posted October 5 These were fitted to fix my wings when I removed the wings the other year, so I got new to reinstall when the wings went back on with a little grease on the thread. Mike Redrose Group Quote Link to post Share on other sites
Keith Wigglesworth Posted October 8 Report Share Posted October 8 This is a little tool I made up to hold 1/4 in screws in the lathe for dog pointing or similar. Anything like this helps when you are cutting stainless. Keith Quote Link to post Share on other sites
RogerH Posted October 8 Author Report Share Posted October 8 (edited) That is very handy for when working on round head fasteners. Roger Edited October 9 by RogerH Ypto Quote Link to post Share on other sites
RogerH Posted October 9 Author Report Share Posted October 9 Hi Folks, I bought some longer screws the other day but before turning a nose on them I found an issue. So I rifled through my odds and sods and found three 1.5" long screws and turned a 3/8" nose on the end. Did they fit !!!! Like a dream. The nose fitted a treat and alugned the n ut so the thread could take hold. I decided not to use the HU706 style screw as I was not confident it would align enough.
