It's good that you leave the mistakes in your videos Michael,I'm sure others would edit them out making them appear better than they are 😂😂. Almost complete now 👍.
You could either cut a flat on the inner curve of the silencer to clear the chain or let the chain grind the surplus ally off and then weld up the hole.
Silencer looks great - think a bit of a sketch and some or your trademark cardboard templates would have helped, don't like to see you getting too frustrated. The Greaves is handsome in it's quirky way, they were quite a thing in their day so looking forward to your riding experiences. Keep up tge good work, always a highlight on Sundays.
Have you considered doing a smoothing pass on your welds? My ability to weld aluminium is similar to yours, I weld everything first and then do a second pass to even the fillets out, always looks a lot better.
I'm no expert and please feel free to correct me if I'm wrong but I'm not convinced that silencer is going to work. The point of having a mesh structure and wadding in the silencer is that the exhaust gasses enter the silencer and they have to pass through the mesh and wadding before exiting. It makes no difference whether they go from inside to outside or the other way, outside to inside. On this silencer both the inlet and outlet pipes are on the inside of the mesh, the gasses will simply come in and out without touching the mesh and wadding, none of the gasses will pass through them.
The gas shouldn't pass through the wadding at all. It should pass through a perforated tube, surrounded by the wadding. It's purpose is to absorb the sound waves, which are energy and have no mass and not to restrict the flow of gas, which is matter and has mass. The wadding would also soon be sodden with carbon and waste two stroke lubricant if the gasses passed through it.
@@retromechanicalengineer OK, so if the wadding is wrapped tightly around the perforated tube how can the gas pass through he perforated tube without also passing through the wadding?
@@andystokes8702 the wadding is on the outside of the tube. In this case, a tube formed by the mesh. The gas passes through the space in between, as it is being drawn by the open end of the tube, it has flow. Of course, it will fill the space to some extent but don't discount that it is flowing. There will be some staining and absorption of oil from the wadding, that's why it requires to be changed periodically, but it doesn't actually flow through the wadding. The sound waves are a different kettle of fish. The reason you can hear is because sound waves travel, and they are reflected from surfaces that they encounter. Michael has not built an expansion chamber, so we do not need to get into changing of sign and all of the trickery that comes with that. The waves are reflecting off the surfaces of the exhaust system as the positive pulse travels along. Now let's consider what happens if we introduce a surface known to be less reflective, even absorbent of sound energy...... Take any silencer apart and you'll observe very similar concepts. Best wishes.
@@retromechanicalengineer No, in this case the gasses do not pass through the spaces in the mesh, the enter the 'silencer' and because of the way it has been built the gasses enter into the middle of the tube. They pass through the silencer and again exit from the centre of the tube. There is nothing to make the gasses pass through the spaces in the mesh. The mesh and the wadding, in this case, merely line the inside of the silencer, none of the gasses pass through the mesh. It would make absolutely no difference if the mesh and wadding were removed, the flow would be exactly the same.
@@andystokes8702 you've just explained exactly what I've been trying to tell you. The gases absolutely DO NOT pass through the gaps in the mesh. Not in any silencer system. At least, that is not the intent. The gases flow end to end, hopefully uninterrupted. It is the sound energy that is disrupted by the glass mat. Gas has flow, Sound is a wave. Once you get this, all will be apparent.
Oh what a tangled web we weave when first we practice to re-sleeve...
Hi Michael.I really enjoy your vidios and never miss one.your builds are great and looking forward to hearing the 2 stroke fire into life.
😂 I was thinking I had a senior moment and not realised it was Sunday for a moment. Bonus having a video a day early
It's good that you leave the mistakes in your videos Michael,I'm sure others would edit them out making them appear better than they are 😂😂. Almost complete now 👍.
Michael: Great job, Muffler was worth the effort. Can't wait to hear it run.
Thanks Michael , you are the very best !
That's the first Greeves I considered attractive, and the silencer is a fine point.

Calm down Michael, think of your heart! Nothing is that important.
Looking good , would be nice to see it with the air box or filter on .
Hey Mike no Union Flag, why not put one of those multi coloured ones on and get right up to date.🤣🤣🤣🤣Great Vid keep it up.
came out good. i suppose u will be putting on the heat shield
Like that seat. I think my foam is about half that thick.
As always, the reward is at the and. Beautiful exhaust!!
I think the expanded mesh is too coarse and the packing will blow out quickly.
Muffler looks fantastic Mr. Waller, the entire bike looks amazing!
👍🏴
It was great to see the silencer evolve Michael. The finished result looks very nice indeed.
Best wishes, Dean.

Just take this with a pinch of salt.. Is it Michael Waller or Michael Wally lol.🤣

Utter nonsense Michael scrap pile time now unsubscribed
