Ian,
Never have any problems with BLackgates, I use their Catalogue and order by phone , normally 3 day delivery and have used them for years.
Blackgates in my opinion are one of the best stockist for what I want, the engine standard is all that I require as the rest is built from my stock material.
As we don't have any Model Engineering supplier in Scotland I have to order from the South, Blackgates will supply what ever I need and to the lengths that I need without having to go to a metal stockist in Glasgow and have to buy round bar in 3 m lengths some times 6 m lengths..
Wish I lived down the road from them like you which would save a bundle on postage.
As to their web site, can't comment as I never use it.
George.
