Thread: Car Boot Find
19/09/2018 10:15:12

Hi John. Quite possibly from an Atlas/Clausing lathe. They used the double keying method. There are several YT video's of people making the gears in ali or plastic. Also a couple of video's on making the plain bore adaptor.

Thread: Cleaning castings by hand
17/09/2018 16:22:52

As JR says a casting kit will need machining before it will be of any use to you.

Have a look at mrpete222 on youtube he did a recent video on building a small engine with just the use of a drill press. This could be taken to a much higher level of detail than he shows. It will give you an idea for the assembly of such a project but not much on the machining side.

Thread: Help wanted on 2 inch build
17/09/2018 16:11:41

Hi Trevor. It would help if you turn off your predictive text or check your words before posting. devil

Is no one at the club able to help you as they seem to be close by ?

A couple of photos would help to allow people to how much work needs doing. Sorry I am not close enough to help but I am sure someone will be along soon.

Hi Andrew welcome to the forum. Plenty of help available from members in here. You could do a search and see if you get answers to your questions from posts submitted previously. If not just ask away and somebody will usually have the answer or a good work around for you.

Thread: Backlash Allowances for Gears
13/09/2018 13:53:10

I stopped watching Keith Rucker a long time ago when I realised that he is a hammer & chisel merchant. (Who belts gears on a shaft with a steel hammer)? Besides that he is a bit to smarmy for me.

Thread: Hello from St Ives Cambs
10/08/2018 15:28:03

Welcome to the forum Simon. I was born in Huntingdon and have many relatives in St Ives but now live a few miles further away.

Look up mrpete222 on You Tube for some very easy steam engine projects. You don't have to follow his ideas but it may give you some ideas and inspiration.

Thread: Colchester Chipmaster what to check for
08/08/2018 15:08:04

Go check it out. If its obvious that the parts are from different machines don't pay for it as he has described it incorrectly Very carefully check that all the parts are there even if it takes a couple of hours. Any genuine seller will not have a problem with you doing that. Always go and check out a lathe or for that matter any machine before you pay for it

Thread: Thread cutting with carbide inserts
29/07/2018 12:13:51

I use carbide form inserts to cut all my threads now ( metric/imperial LH/RH). I mostly use straight plunge and have not had any problems even up to 2".

I have made all of my backplates & ER32 collett holder threads @ 1-1/2" x 8 tpi and they all look good.

Just made an Acme cross slide screw for a friend and it came out really well.

I limit the cut to around 0.008" until the last couple of finishing cuts and use plenty of thread cutting oil or paste. I do not usually exceed 100rpm on my Boxford for thread cutting.

To be honest I rarely use HSS these days unless it is really required.

Thread: Model Engineering threads
26/07/2018 22:21:47

Its all out there on the net or in Engineers handbook etc etc. As Chris says GOOGLE is a wonderful thing.

Many people have their own little tricks for jobs they do but when it boils down to it there is a set of published standards that industry uses.

Thread: Selecting and installing steel mesh for a concrete pour
19/07/2018 19:56:43

Totally agree with Raymond Anderson. Either you are having a base that will support the houses of parliament or someone has conned you on the required amount for your base. Its very basic maths here. ie length x width x height gives a cubic measurement. The builders who laid the floors for my extension stood the mesh on pieces of thin brick paviors about 45mm thick.

Thread: How to remove a chuck from a Boxford model A
10/07/2018 19:04:21

! Posted by Ian S C on 27/06/2018 14:23:25:

! Looking at the spindle, the size of the shoulder that the chuck screws back to is small, the thread 1.5", and the

! shaft maybe 1.75"

Hi Ian.

I have several chucks for my Boxford and none have a need for a washer. Never had one stick on either.

All my backplates sit up against the spindle face behind the register. The register bore on the back plates is 1.5005" and the register diameter is 1.4995". The register bore needs a tiny chamfer where it sits back against the face as there is a very small ridge/radius at the junction of the register and the full spindle diameter/face. Is it possible that the back plate was turned without the chamfer and was stuck on the radius ? I tend to take my chucks off fairly regularly and give them and the spindle nose a good clean & oil.

Glad you got it off at long last.

Thread: Good Old Handbook Suggestions...?
02/07/2018 22:46:40
Posted by James Jenkins 1 on 02/07/2018 22:00:42:

HI all,

I looking for some suggestions of a good old school handbook I can keep in the workshop, one that has tap drill sizes, cutting rates, the weight of steel, number of teeth per inch of BSW - you know the sort of thing. The sort of thing my grandfather would have bought when he started his training 90 years ago! I perhaps don't need one quite that old, but something from the 50s would be fine.

I think in America they have the Machinary's Handbook, but obviously I want something with a more British focus. Ideas?

James

The machinery's handbook is probably the most informative guide out there. It has served in the UK for as many years as I can remember. Engineering tables are Engineering tables world wide. What was good 50 years ago mostly still applies now. I use the small Zeus pads and some others but still use TMH often. I believe the newer versions have been metricised somewhat. There are of course many other good reference books around.

Thread: Service in 2018
15/06/2018 15:34:50

! Posted by DrDave :- Not so nice for the people shipping the order from RS at midnight, though.!

A lot of people like working the night shift. Good job they do as it makes our lives as customers much easier.

Always great service from RS. I must admit though, now I am retired I collect from the Corby trade counter as it is only 10 minutes from my house.

Thread: How to remove four jaw chuck screws?
13/06/2018 22:21:30

I agree with Trevor Crossman1. I have 2 different size 4 jaw chucks and they both come apart by tapping out the yoke from the screw side. I made a forked tool many years ago to facilitate the removal process. I have also braze repaired badly damaged screws & recut the bad portions of thread in the lathe also remade the square sockets. Both chucks still give sterling service.

Martin P . Many people who have read your post probably never comment on ANY post and probably don't contribute to that publication.. I would not take it to heart too much.

Thread: Inverter

As JR said. You need to match the motor to the Inverter with regard to Volts Hz etc. If they are new and supposedly matched I suggest you call the supplier.

30m/min should be about right.
