Re: Fuel pipe solder nipple angle

Thank you Luis for the pictures. I've acquired a Myford from the widow of an old friend and late in life am learning turning. A simple job supported by a few pictures which explain all are encouraging.
Regards from MikeN.

Re: My 48 VH Red Hunter

Re: 1955 NH gearbox oil change

Ah, Molyslip! Long ago & far away circa 1962 I had a Matchless V twinned Brough sidevalver (prob of 1932) which had spent its life pulling sidecars and then a builder's box full of cement, etc. On my first couple of runs at high speed it tightened up, and me being young and impressionable, I put...

Re: New VB piston

Klaus, Is your new piston to replace that in your disaster recorded in your thread of April 23,2015 entitled "VB piston missing a bit"? Can you tell us about the new piston's source and make? A point that bother's me is what you new piston might be heavy; as a guide my split skirt +20 thou...

Re: Removing the ringds from a VB piston

Thanks for that Murray. I've tried soaking for weeks in acetone, hours in a sonic bath and heat cycling as suggested above but have had no luck and now I'm trying to cut them out with a small disc.

Re: Removing the ringds from a VB piston

Thanks for your advice, gents. I've had the piston inverted and soaking the rings in acetone for 3 weeks but no luck on easing them. Heating and cooling was no help either so I'm using a small cutter disc in a small 12v hand held drill device to cut out a piece of the upper ring. I'll let you know h...

Re: Replacing a VB tappet guide

VB tappet removal 27june219.jpg Thank you for your advice, gentlemen! I feared that after some 63 years in place it would be more difficult to remove than it actually was but with a sleeve and cheap threaded rod it came out quite easily and smoothly. The most difficult part was finding a suitable s...

Removing the ringds from a VB piston

Dear all, I've this old piston that I hope has a bit of remaining life - if I can only replace the rings! The problem is getting the old ones out. It was running on Castrol R and the top two rings are well and truly stuck; I can't get even a dentist's tooth pick in at the ring gap (probably lack of ...
