Hi Graham,
It's nice to see you back on this forum. Hope you are well and enjoying retirement.
Les.
Hi Les,
Thanks for the welcome back, sometimes I wonder if I did the right thing, but we shall see.
Regards
Gray,
I keep my unit in an annex, it does not take up any real-estate in the workshop proper, (I cannot afford to waste the space) and is used mainly in this location. As regards costs, this unit cost no more than £20. Some of the items were ex-stores stock, others were salvage items.
My first lash-up for the "blast box", a wooden box with a perspex lid, had no ventilation to the outside as such, but instead had a connection to the shop vacuum. In this design the need for the vacuum was felt unnecessary, but builders can fit one if they wish, using many of the domestic waste fittings. Two years on of occasional usage the filter is still clean. No doubt my internal baffle allows the heavier particles to fall before the air exits the filter.
Regards
Gray,
