Re: NH chain alignment

A bit of an 'aside' . . Whilst browsing through bike bits on e-Bay I came across this laser wheel alignment tool: https://www.ebay.co.uk/itm/Laser-Monkey-Wheel-Alignment-Tool-Tru-Tension-Motorbike-TRI-YAM-SUZ-HON-DUC-KAWA/283424554005?fits=UKM_Make%3ATriumph%7CUKM_StreetName%3ATiger+Cub%7CUKM_Model%...

Re: Redune Tractor Festival !

I love Agricultural Shows, particularly those with old Farm machinery (I live on a farm). I always come away feeling guilty - I MUST finish the renovation of my 1976 'Zetor 6718', its been blocking my garage for too many years. Its good to see that the French look after their old stuff too. Nice pic...

Re: sq 4 oil pressure....

I used to run my MkII on Castrol Grand Prix - Straight 50. It was difficult to start on a frosty morning but was plenty thin enough with the motor warm. It used to run at 52 psi on the road but tick-over when hot was only about 10 - 15psi from memory. I suspect a 20/50 multigrade is a bit thin for a...

Re: LF 250 - pictures please

I now have another drawing and dimensions from 'BertieB'. He also sent me his wheel spindle which is quite different to the one from my 'cooking' Triumph T20. It may be from a "Super Cub" or a "Bantam Cub", who knows. As long as I have the dimensions for the hub bearings I can wo...

Re: vch headgasket

The head and liner have to be 'lapped' together with fine grinding paste. I had to machine-away some alloy from the top of the barrel to get the head and liner to make contact and it all works OK now. I wasn't sure how much clearance to leave around the liner, as the head has to be pulled down to ke...

Re: Turning on a mandrel - Loctite?

I have also used Michael Jobson's method - the hours I've spent making one-off single-use parts :roll: . However, if the bush isn't required to be 'built to a thou' then the glue would be worth trying. The bush would have to be a good fit on the bar though as otherwise there could be run-out in both...

Re: Turning on a mandrel - Loctite?

I would warm the round bar and then apply some 'hot glue' from a glue gun - slide the bush on and let it cool.

Hot glue re-melts easily so it will all come apart without a problem.

Just don't go at it like a mad thing and get the bush hot while machining ;) .

Re: LF 250 - pictures please

I asked "BertieB" for some frame dimensions and he sent me some pictures. This one in particular isn't sharp enough for my purposes as I need to know a few things: LF - rear frame width.jpg Specifically - 1. What is the actual width of the rear frame between the inner faces of the wheel sp...
