Thread: 'Hacking' an inverter
07/03/2016 18:30:37

I am happy with my Chinese cheap (sub £95) inverter running my Bridgeport. It is rated to power a bigger motor to allow for start up load. All this was set up by a friend who has 5 of these inverters running his workshop contents.

It is a much smoother not to mention cheaper solution to the static inverter powering my 3hp lathe that cost around £400

The spirit level type sold by the usual suspects are cheap and effective. It is nice to make your own kit though.

Space is usually the key but also think about just what you want to make. I do not make models but make/repair/restore parts for old motorcycles, that dictates larger machinery. Welcome along and enjoy the board and the new hobby.

If any folk are willing to do a relay I am between Lichfield and Burton on Trent. I would be happy to store for pick up or drive up to Sheffield.

Not sure of your machine but it sounds like a simple turning job to make one.

BSCY is 26/20/and 24 TPI 60 degree angle. Things like wheel spindles on pre war bikes are 20 TPI in either 1/2" or 5/8" I sometimes have to use UNF if the correct BSCY tap is not available.

John, Automotion's site gives the nut dimensions. It may be possible to split one or ask them or another similar supplier to make a special to your requirements.

If you are changing a pair of nut/leadscrew it does not matter if thread form differs. Just pick correct pitch, their imperial pitches are listed as acme. For my lathe cross slide I went up from 15 to 16 mm diameter to suit availability of pitch. Chris.

Have a look at Automotion Components web pages. Lead screws and nuts of all sizes and pitches are available.

I have just bought a 1 metre length of lead screw for about £16 plus nut for similar money all plus tax/delivery.(longer lengths up to 3 metre available)

A bit of simple turning to suit the ends and I will be up and running. No connection just a happy customer.

They come up in Old Bike Mart at times but good ones are around the £1200 mark.Brilliant little bike loved by many. Heed what Tim says though and check the rear mudguard/seat pan they rot big time.

Thread: Long expanding mandrels
26/02/2016 22:26:20

You may get away with setting up a piece of 3/4" (19.05) between centres and polishing a couple of thou off it and maybe a thou or so taper. Then assuming the inside diameter of the tube is OK warm with a heat gun and slip it on the mandrel. Turn to size then warm to remove, you may need to wrap some emery round it to help get it off when warm.

Thread: Slip Gauges
26/02/2016 09:37:53

I concur Bob, the sort of thing most of us are turning out the quality of slips is good enough. My set was made up from several old boxes that where lying around unused at work. If I am setting up a sine bar I put a micrometer on the stack as a check anyway.

If the plus gas soak does not free them try a gentle heat with a heat gun. Not to warm though there are springs in there.

Thread: What Did You Do Today (2016)
24/02/2016 22:36:01

Had a BIG tidy up in the workshop today and completed the engine build on my pre war bike. Then started to make a new carburettor slide for it.

Thread: Steel...what kind?...
24/02/2016 22:31:13

Sounds like very high carbon. Bin it and start again with a known quantity.

Thread: Another Mystery Tool

That looks home made to me. I have seen most variations on the Clarkson theme.

Thread: Aciera F3 - info on headstock dismantling, please

Hi Roger, as promised I looked for a manual when I visited my old work place. Sorry to say I did not find one.

Thread: Slip Gauges
23/02/2016 22:06:38

I have a full imperial set, used for checking slot widths/setting sine bars/marking out/checking micrometers. The list is endless.

Thread: Colchester student oil
23/02/2016 09:07:07

Most machine oils are specified to a DIN number. I use the 68 as slide oil and in the apron and 32 in the headstock.

32 is a hydraulic oil but used in a lot of lathes I scrounge it from where I used to work as they buy in 205 litre drums.

Where are you based ? if in an industrial area it is best to buy from stockists in 5 litre size much cheaper than the dealers 1 litre bottles.

Yes one of life's unsung heroes. I recently read his book the title of which eludes me at the moment.
