|Thread: Chuck backplate mistake|
I've always made the hole as snug as possible because it seemed to me that was how it should be. One of my original Myford supplied chucks was so tight it needed a light scrape before it would fit the spindle. I read several arguments about the fit, more than one stated that the hole should not be a close fit because the register was the back face and not the bore, the thread took care of centralising the chuck. Several of the aftermarket backplates I've bought are a good rattling fit despite which the chucks seem to fit with acceptable run out (for a 3 jaw chuck).
I wouldn't worry to much about a smidgin but you need to keep it below a gnat's whisker.
|Thread: Silent compressor problem|
Bambi compressor BB24V
Thanks everyone. Capacitor seems OK, I fitted a new one, no difference. I previously used it with my Bridgeport Spraymist system, the air usage of which is fairly low. I noticed the compressor getting hot when I was blowing out some carburettor drillings which emptied the reservior two or three times, perhaps I'm expecting too much of it.
Oil level is 1/2 way up the sight glass. After 10 minutes running the casing is much too hot to touch. Motor cuts off when pressure in tank reaches 100PSI. No noises except click when motor starts, very slight vibration when running. I haven't used it much, I bought it to use with my Bridgeport Spraymist coolant system, don't think it was running hot then. There is an external capacitor, I will replace it and see if matters improve.
Many thanks, help most appreciated.
I have a Bambi silent compressor. I used it recently for about 10 minutes and the compressor unit is running VERY hot. The oil level seems OK. Is this a fault or do they normally run hot?

Adams oiler was leaking on my ML7, (it's about fifty years old but appeared to be in excellent condition, apologies to other ML7 owners who will know what comes next!) would empty itself over two or three days. I had a good look at it, oil seemed to be leaking past the needle. I removed it from the machine, couldn't see any problem with it, I thought there might be some debris holding the needle off the seat. So it took it apart, I carefully examined the plastic bowl for cracks - nothing! I checked and cleaned the other parts and decided to reassemble. When I picked up the plastic bowl, it fell apart into four pieces, there were cracks radiating out from the hole in the top. It seems that removing the top nut allowed the bowl to change shape and crack. I still don't know why it was leaking but I don't suppose it matters now.
I'm now looking for some 30mm glass tube. Have you seen the price of small drip feed oilers?, 50ml ones are about £3.50 frim China, why are they asking £22.50 for 25ml ones?

Next week, next Tuesday etc. Means the week or day AFTER the next. Seems peculiar to Essex.

|Thread: 5 Cylinder Rotary Air Engine|
I recall fizzy drinks bottles being used for on board CO2 tanks. Can't remember how much pressure they would take but it was a lot. Should be easy enough to pressure test a few bottles with a boiler test set.

Reminded me of an engineering firm who made motor scooters in the late 50s. The handlebar bracket was a Mazak casting, the handlebars tended to fall off.
|Thread: What are they?|
It is a chamfer tool for round metal bar and threaded rod after cutting. Not a new idea, I had a similar item 50 years ago for use on wooden dowels.

The internet is a golden opportunity for thieves, there was (is?) an almost identical copy of the government road tax renewal site. They rip you off for checking and submitting your road tax application, an unnecessary service and one which is deliberately intended to defraud. A lot of care is needed when dealing on the internet, make sure that the site you connect to is the site you actually want, search engines are just as likely to direct you to the people you want to avoid.

I wouldn't mind getting it all wrong if my jobs turned out like that.
I like the drill jig, just what I need for my Clarkson.
Very nice work Joe!

Very nice work on the rack. You could probably buy a Bridgeport for the cost of the Tom Senior and get it ready made.

I would go with photo etching, if they are a standard size you could do the artwork once and print them as needed.
