Breathers in the block
#1
hi
Does anyone know where I can get a couple of the thimble shaped breather/mesh things that are inserted in the base of the block. The block I have for the engine I'm building up has had both removed.. I suppose one question is, are they actually required? 

Any guidance much appreciated

You don’t really need them only use is to stop you dropping Collets into the sump

That sounds like a good reason to me!

There was talk of somebody going to make these, I always pick up any I see - they are often missing.

I have used old sump gauze pushed into the hole from above, so no chance of it dropping into the sump

so any other creative answers for when the thimbles start to fray a little? Has anyone found another cheap modern part to fit?

Why bother? Only need to plug with cloth when tinkering .

Exactly — but do remember to remove after fitting pins / collets, — easy to forget in all the excitement.
