Very slow progress, too cold in the unit, no heating :(
.
Made a few brackets, take forever to complete:

2 x Oil tank brackets, one of the two top mounts still to make
1 x Oil cooler bracket
2 x Seat rail tube plugs
.

.
Next job is to make up the swinging arm pivot plates but waiting on a 13/16" slot drill to make the slots for the swinging arm adjustment

Just been reminded that the idea for this project started March 28th 2009 which is 10 years ago :shock: Where does the time go?
.
Completed some work on swinging arm pivots:

4. Old mounts removed.jpg

.

In some of the previous pics you probably notice the poor welding. :shock: Finally admitted to myself that welding is not my thing and all critical welding will be outsourced to a professional welder.

If a weld looks bad it is bad

Hopefully I will be able to post some further progress towards the end of April when I get the frame back from the welders

More work on brackets.
.
This time it's the rear shock top mounts. Been putting off making them for ages as I knew it would be tricky................

I've made them from 3.0mm mild steel. The originals were 12 gauge (approx 2.6mm). I didn't use any heat just a BFH :lol:

The final shape is effectively a 'U' shape but angled, so each bracket has 4 bends. My first attempt failed as I bent the bends in the wrong order so I didn't have room in the vice to make the last two bends. So lesson learnt, second attempt, bends 1 and 2 first followed by 3 and 4.

Made up the rear mudguard bracket for attachment to seat rails. Looks simple but the bracket is offset by 8 degrees to allow for the radius of the mudguard. Lucky I had drawings for guidance. Still took three goes to get it right. I will drill the mount points for mudguard and grab rail once it is securely welded in place.
.

Here's the list of welding jobs on the frame for my local friendly welder to complete:
  • 2 x tube bungs
  • 2 x rear suspension top mounts
  • Head steady bracket
  • Oil cooler bracket
  • Steering stop
  • Rear engine mount - bottom
  • Rear engine mount - top
  • 2 x frame lugs to attach skid plate
I'll get the frame blasted before I drop it off at the welders. Let's see how we get on..........

I've still got a lot of work to do on the frame. Main task will be to bolt the engine in place, mount the swinging arm and rear wheel and then check sprocket alignments. From there I can position the rear mudguard which will then let me locate the oil tank and battery platform plus all the remaining brackets

Hi Beat

In essence it's a BSA A65 frame - pre oil in frame with a few modifications. Hopefully things will become clearer as the project moves forward.

As you say lots of work ahead :grin:

You going for snail cams on the swing arm SteveS...OK yes, I see it now... And your points cover is nowhere near your points...what you going to do there?

Hi Gerry
.
Ignition will be fired from the regular location but as you say the points cover will be miles away. Since the 5 speed gearbox projects such a long way out I had to fabricate a couple of covers to get everything to line up. The final outer cover at the front acts as a small toolbox which should be water tight - finished off with a Fury alternator rotor inspection cover.................

All is clear, but I think I'd put a drain hole so that condensation has somewhere to go, not sure what small tools will fit in there, maybe you could use it to warm a sausage roll or pastie or something....keep up the good work....

Just a heads-up about the carburetor mounting on the B50 (unless you're using Fuel injection!) - - the right rear downtube on the OEM B50 frame always fouls the carburetor unless you're using stock Amal carb with no manifold extension. You might want to fit the cylinder and head on the motor in the frame to ensure that right rear downtube will not be in the way of whatever intake set-up you plan to use.

Yes, I will bear that in mind. Hopefully I will have a better idea of where any problem lies over the next few weeks.

With a bit of luck, the A65 frame will be wider than the B50 as it was designed to have a couple of carbatooters in that space, but who knows with this Heinz 57? :oops:

While waiting on some more welding to be completed I've been working on the rear wheel. To help with the wheel build I invested in a truing stand. I have been looking around at the various ones advertised and ended up purchasing the one here
.
It's fairly robust and will certainly be more than adequate for the work I have planned. The only changes I have made to the stand is to drill 4 holes in the base to secure it to my bench.
.
Motorcycle Wheel truing & balancing stand.JPG

.
Laced up the wheel with stainless spokes. It was helpful to have a spare wheel nearby to ensure I got the lacing pattern correct. There are 4 different spoke types for the conical hub, 10 x inner long, 10 x outer long, 10 x inner short, 10 x outer short. I dipped the threaded end of the spokes in some waterproof grease prior to fitting.
.

.
Once I had fitted all the spokes I put the wheel in the stand and tightened all the spokes until the threaded part of the spoke was covered by the nipple. When I get the swing arm back from the welder I can set it all up in the frame and ensure the sprockets align and then centre the wheel in the frame

I have a very similar stand and it is more of a balance stand. When truing the wheel you might want to hold the axle solid and spin the wheel on the wheel bearings. That takes any play or wobble of the axle, locators or bearings out of the equation. Great build. I look forward to your updates.

Hi Scott

Thanks for the advice regarding the stand. Will bear it in mind when I get to the final stages of truing the wheels.

Managed to lace up the front wheel which has a Triumph Meriden disc hub. I will be fitting twin discs. Still need to centralise the rim but at least it's all together

They look great! And it's a good idea to do the final tightening in the swingarm and front forks.

As for stand, I just use an old swingarm mounted in a bench vise with the actual axle with spacers to be able to fix the position of the hub so it can't move during the tightening phase.Worst part for me is to get the runout exact, as having to pull it one way or the other can affect the runout. Also, with old rims, I find that the joint where the ends are welded together always results in a high or a flat spot of up to 1/16th inch that I could not eliminate. New ones are better, but still not exact.

A few more parts fabricated, together with the completion of the rear wheel.
