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...

The 'VH' looks superb, a good buy for someone 8-) .

Unfortunately I've already got one (I should have kept my Square Four) :D .

Re: Daily Fixing and Riding Diary on an Ariel 2019

Stupid security gates with finger print recognition wouldn't let me through. Took 30 minutes and the help of at least 5 people to finally get me through the turnstiles. You did take your riding gloves off - didn't you :lol: . My uncle worked at Unilevers in Avonmouth for most of his working life (a...

Re: Grades of Steel

I have recently taken to writing the grade on the stock with a paint marker pen, I have to do it as soon as it arrives and I can match it to the Invoice. You are more organized than me, my new stock is either in a crate on wheels under the bench (short lengths) or leaning against the wall in the roo...

Re: VH-crank - oil supply

I've been told by some of the Panther Owners Club gurus that I could probably block off that barrel hole on my M120 without any ill-effects. You have a rocker oil feed - so oil will be circulating, dropping into the timing chest and then overflowing into the crankcase. Once the crank is splashing i...
