45 - A new addition

 Wow - four months have gone by and I haven't posted a thing. Well to tell the truth I haven't done much to the bike over the summer. I eventually left the tank with Brian the boat repair man and it's kinda been sitting there since. The rest of the bike is pretty complete so there wasn't a lot to do and I get easily side tracked with other things.

 I took a notion to buy a lathe for the workshop. After studying the internet I ordered a 290V from Warco. This is about as big as the variable speed model bench lathes go. It has a 6" swing and 28" between centres. 1 1/2" spindle bore and 3MT tailstock, so it should do most jobs on the motorbike for me. Also it comes with 3 and 4 jaw chucks, face plates steadys etc.

It arrived on a pallet inside a packing crate, luckily the shop at the end of the road has a forklift so he was able to lift it off the lorry and set it in my garage. When it came time to install it I borrowed an engine lift from a mechanic and put her in place in the corner of my shed.

I've been very please with it so far. It's accurate, the digital read out makes things real easy, and you can machine at a decent rate with the power feed, so it's no mickey mouse machine even if it was built in China. 

44 - Tank repairs

 This is one of the last big jobs to tackle. The problem I faced was that before I could get the tank painted I needed to do something about the interior. Twenty odd years ago I had put a Petseal tank sealer solution into it, but this had split and cracked. I didn't think pouring in more on top of it would be satisfactory and there was no way to completely remove the old stuff because of the limited access.

 So I had no real choice but to cut it open. Before I did so I found a local boat repair man who specialises in fibreglass and gelcoat repairs. He's going to glass it back together for me and we'll find the best product for recoating the interior. 

 It was a dusty job but not too difficult to open it up. I cut in to it with a thin disc about half an inch from the edge then went round the curved tunnel with a hacksaw blade. Once open the old petseal came off in big pieces, only here and there was it well attached. 

43 - Speedo Bracket

 Yet more fabrication. This time a bracket to hold the speedometer. Looking at the drawing in the parts book I tried to copy its design. I wanted it to hold the speedo in out of the way, really close to the frame. 

 I marked it out from a piece of 4mm stainless steel. ( I love stainless - its the only way to make stuff that's going to live its life outdoors on a bike.)

 Once it was filed up I used a bit of heat to twist it into shape. It worked out really good, with minimal clearance.

42 - Guard fitted

 I finished the guard by fabricating a little stay and getting it welded on. I know the original was riveted but I opted for welding.

 Next on the list of things to do was make a brake rod. I bought a piece of 6mm stainless and bent and threaded the ends. I didn't like the way it just touched against the spring of the shock absorber so I put a little joggle in it to make a bit of clearance, looks much better now.

 I made the winged adjuster nut from stainless steel. Just a piece of bar drilled and threaded, then two little slots milled to hold the wings in place while I brazed them in. The front end was radiused with a cutter to stop it turning against the barrel. 

41 - Chain guard cont.

 After forming the curve on the top of the guard I marked it out then cut and filed it to shape.

 It needed a dimple at the front to allow for the head of a screw, so I made a press tool from a couple of bits of scrap bar. It worked out pretty well.

40 - Making a Chain Guard

 I thought I'd better make a start at making a chain guard. A friend in work cut me a sheet of 1.5 mm aluminium. The folders we have only make square folds so I took it home to come up with something myself.
 I had a rummage round the shed and gathered a few bits together. 

 Some plywood and 22 mm copper tube was enough to make a simple folder and it worked very well.

 I already made a template from some card so I'll use that to mark it out ready for cutting and filing.

39 - Rebuilding #1

 Now that I have most of the bits ready it's time to start rebuilding the bike. 
 The new stand fits very well. I was going to make a jig for John to help when he welded in the pivot bracket, but he said "don't bother I'll just hold it position myself" It turned out absolutely spot on. It has a nice line parallel to the swing arm and the spring has good clearance with the tyre.

 The springs look nice now that the're chromed and I have a new chain fitted over the old sprockets, but they were ok. The tensioner and torque arm have been zinc plated.
