hamster juice knackers Sunday mornings so didn't get going 'til after lunch ...
bench time required ...
I'm glad I put a new mask on to wire brush that old manhole lid with the 5" Mak and wire wheel .... dust - unbelievable

then set about creating a new frame for it as it's not the original lid and that plastic surround/base is a piece of crap -- did outlast the tin lid though
had to get the tarp cover rolled back off me steel stock, to find what i wanted, buried under heavier stuff ... worked a treat - forgot to get a pic though - real easy

start of the frame ..
then set an inner lip to get the top height right and give it a bit of a seal too
frame in the background is to support the lid's surround
stitched together ......
and firmed up
second trial fit ... first one 'fore I joined the two bits
and yes I tried it in the chamber too
coat of supposedly shiny sh1t ... which is more of a satin finish .. dries quick though and seems to hang in there well
the boss wanted the top of the lid Pewter (looks a bit like galv TBH) ...
so ....
good as new

gonna wait 'til it's been emptied Tuesday, 'fore I go fit it ... boss is happy though
had a lovely 'mackerel sky' last night
