Looks right! Full size next? Worth a Jampot article (I hope)?

Google perforated stainless steel tube at the same time maybe :)

Interesting, I used this mesh to make a replica air cleaner for my lightweight

I've not managed to track down a suitable means of rolling my mesh yet - I feel rolling it will yield far better results than "coaxing" it around a steel bar with the aid of a big hammer!

I did take one of the better, inferior filter meshes (read cheap if that makes more sense!) and trimmed the ends up and then made it somewhere close to the right length with the addition of a couple of rings. It turned out that 22m pipe fitting Olives were just the right diameter for the rings and the tapered OD lead was spot on with just a little fettling of the ends of the mesh. They were soft soldered into position and then trimmed to length by wedging them on the end of a suitable file handle to maintain the circular shape whilst they were sawn with a Junior hacksaw. A final tidy up with a file and then a good clean in thinners followed by scrubing with washing up liquid and very hot water.

I'd better start sewing ......

I wonder if it will work?

And this evening I have been sewing ... and then my wife took pity on me. She's far better at sewing then me!

I tried the overlapped joint approach but, try as I might with straight or bent needles I didn't get very far (about 3"). So, just as an experiment Mrs GL finished the job by butting the edges together and sewing across the seam.

The net result? A re-felted filter that looks like it's just the job, with the right OD over the felt ends and maybe a mm or two a bit too long. I feel a second go at the felt is required; without the interesting transition between styles half way along! I'll use either the butt joint or maybe have a go at the most easily sewn, external seam although I can't help feeling that will end up with too much spare material.

Anyway, I think I'm on the Home Straight with it now and I think you'll agree, it seems perfectly "doable" - I'll just have to wait for a 1000 miles or so until the next oil change to see if it fits and works!

Well done! The edge sowing does seems to be vital doesn't it? I cannot see if the turned over edge has been tacked to the mesh as it is on my original sample.

Not on this one but it will be on the "production" version :)

A "proper" felt liner has now been made with a butt joint, kindly sewn by Mrs GL. Made-to-measure, the felt turned out to be 8" x 2.75".

Final Filter (3).JPG


This left ~20mm sticking out of each end when inserted.

Final Filter (1).JPG


The ends once soaked in hot water fold back really easily. Once dried, the ends were stitched onto the mesh to make sure they stay in place.

And so I present to you Production Filter #1 ......

I'm calling that a success! :)
