Thread: Holding End Mill on small lathe
14/03/2020 19:20:11

Some mini lathes do not have a full depth morse taper in the headstock but if yours has I'd opt for a MT1 ER 25 as the range of collets is larger than ER 16. My Boxford has an ER40 on a back plate but it is a bigger lathe.image00002.jpg

Thread: New lathe

Ask away, owning a 5" AUD for quite a few years I know it fairly well.

09/03/2020 15:35:05

I have a late 5" metric AUD so my answer would be go with the Boxford.

Thread: Speedometer Ratios
05/03/2020 10:28:31

It might be worth speaking to Speedy cables as they can recalibrate speedometers **LINK**

Thread: Cylinder bore measuring
22/02/2020 12:11:35

I have this for measuring bores 0.4" to 1.4"image00003.jpg

Thread: Basic battery charger
08/02/2020 23:16:33

Just place a good battery in parallel for around 1 hour.

Thread: Compressors
19/01/2020 13:17:51

Compressor output is usually quoted as x cfm but often miss the last bit "free air delivered" or running at atmospheric pressure.

Thread: To use chuck or collets
10/01/2020 15:42:57

You can get a collet chuck with a Myford thread as I have one on my Dore Westbury milling machine Also have an ER40 on a back plate on my Boxford which I tend to use over a 3 jaw chuck with round bar. image00002.jpg

Thread: Long bed lathes affected by the tide

BHC had an issue with wing jigs for the BN Islander when they were subcontracted to make them and were setting them up, as the tide came in the concrete they were on moved throwing the jigs out of alignment.


FYI The main hanger Saunders Roe/BHC is now Wight Shipyard that build cats like Red Jet 6 and 7, the other site south of the floating bridge is now GKN making wing tips amongst other things and the training school is now also part of GKN.

Age old adage you pay for what you get.

Thread: Aluminium welding
15/11/2019 16:31:16

It depends on the material and the kit you have, TIG would be my preference.

Thread: Lathe chuck guards - how many folk use them?
07/11/2019 00:07:18

When I purchased my Boxford AUD metric lathe (ex school) it came with interlocks on the chuck guard and gear cover so they both got removed as I like to apply a little oil to the gear train and the guard is just a pain.

Thread: new computer
07/11/2019 00:03:25

Doing it your self using Crucial's or Kingston's free software is straight forward, as I said earlier have done it a few times now and well within most peoples capability and is probably how the computer shop did it. I assume the computer is now booting much faster and in general faster which extends it's life for minimal outlay.

Thread: Installation of a Myford (or any machine tool)
06/11/2019 09:02:23

My Boxford sits on 4 x 2 treated timber to get it to a more comfortable height, raised 8" by doubling up 4 x 2.

Thread: new computer
04/11/2019 22:02:16

I doubt a 9 year old PC is too old to accept a SSD hard drive after all the Intel Core I5 is now 10 years old. May not work at optimal speed but still considerably faster than a mechanical drive. Do you know make and model of motherboard and processor? "Belarc Advisor" will tell you, only a small application.

Dependant on current hard drive size you may want to consider a new SSD hard drive from the likes of Crucial + kit as it comes with a clone option to copy your current drive to the new drive, instructions are simple enough, I've done it with 3 desktops and a couple of laptops all with a major speed boost.

Thread: ER32 collets from 20- 30mm
28/09/2019 23:47:12

I use an ER 40 collet chucks in my Boxford on back plate or in one of my milling machine and ER32 in the other milling machine.



Thread: 3 phase - radio puzzle

Generally if you have a VFD with fitted filter it will trip your RCB which is why a lot of suppliers sell them without for home use.

regards Martin

Not had a problem with mine fitted with a filter and property on RCBO's on each individual circuit.

Thread: Upgrading to fibre optic broadband

There should be another side to this question and that is what speed of connection do you actually need? There seems little point in paying for a connection speed of umpty Mbs when something a little slower will work just as well. A bit like buying a superfast car capable of a speed you'll never use when something slower will still get the job done. The needs of couple with two teenagers are going to be different to the likes of me and the wife, with a wife that works from home connected to the London office for 8 hrs/day.
