Dead right there. (Just to upstage you I have two of the Clarke bandsaws!
) Myford Green, that will upset the purists! Shouldn't it be red?
That machine is in lovely condition, I wonder what it was used on at Hawkers? Probably bought in to drill two holes in the widget held in a special jig for the upper thrust trunnion on the TSR2!The Lycoming Grey is supposed to be engine enamel from an aircraft supply
company, I have not tried spraying yet but it wets out nicely with a brush. I hope it resists the heat as well as it applies.
.If I remember right Alfred Herbert Coventry was one BIG machine company and don't know if you are aware but I think you have the company colours too. Sky Blue. And it will still be going when half the population of the UK is pusshing uo daises.

Got a bit more done today. spent ages flushing the grit out of all the threads and blind holes. got them all spotless in the end. spent ages today trying to find out what jacobs taper is on the spindle nose. i think it's a 1jt which limits me to a 3/8 chuck but i suppose i can live with that. the chuck it came with is only 1/4inch because when it was new it was a high speed three phase with a top speed 12000rpm but with smaller pulley on the motor i recon i can get it down to around 500rpm on it's slowest speed. hard to find any info on Herbert machines. anyway still loads to do yet. this is where i'm at. oh by the way having one clarke bandsaw is bad enough but two is nothing to be proud of

The first one has been tweaked and works well now, the second one is to be converted into an upright bandsaw with a 3rd wheel. No coolant as yet, on the todo list.

yes it's fixed. the jacobs taper is machined on the end of the spindle. morse tapers were not accurate enough for such high speeds.12,000 rpm don't forget. the spindle has roller bearings in the top and botton. it has a lever to lock the spindle and a threaded collar to push the chuck off the taper. i suppose you could trash a very expensive spindle qiute easily. i was only kidding about the bandsaw they're ok realy

morse tapers a ok at lower speeds but if anything is slightly out of ballance theres a chance it could come loose thats why morse taper in never used on a milling machine because any side force will loosen it. anyway i'd much rather use the small saw than the bandsaw. when you're using the bandsaw you set it running then walk away but with the little one you've just got to watch it cos it makes me smile every time

never seen a churchill looks like a nice heavy drill and no doubt very well made. how many clarke bandsaws will still be going strong after 55 years i wonder

with a drawbar exactly. can't come loose with a drawbar. i suppose a jacobs taper could come loose just the same but at least just the chuck drops off. and by putting a jt on the spindle it limits the size of the chuck
