Thread: Carbide end mills
28/03/2016 10:22:32

Roger/KWIL I am sure my rattle is pulley bush and belt wear. One of those must do one day jobs, I am part way through making a new cross slide for my lathe to cure some issues but there is never a right time to have a machine out of action. I did see an American Bridgeport spares site that gave good how to do it instructions so when the lathe is done may be the mill next.

Thread: Couple of things at Lidl
27/03/2016 12:01:37

My cheap supermarket compressor has given me around 10/11 years service and is used at least three days a week. My only complaint is it is a bit to loud. I seem to recall it was £49.99 with tools from Neto. I have not seen a Neto store in years are they still around ?

Thread: Carbide end mills
27/03/2016 11:44:36

With cutters of 6.5 you will be OK for speed. My Bridgeport varidrive rattles a bit above that speed so it is a self imposed limit and I have no problems running carbide cutters. For ME work think of them more as posh ridged cutters for a nice finish rather than high metal removal rates.

I have the book "Wings on my sleeve" on my Kindle. Well worth a read. I saw the TV program first time around worth a re run on I player.

Thread: Milling Machine
25/03/2016 13:59:33

I am with John on this. Get as big as you can, I do mainly bike stuff and would not be without my Bridgeport turret mill which has a 4" spacer in it. A pair of crank cases on a tilting table plus a boring head soon swallow up daylight.

Thread: Stuck Dial Gauge

Dip a cotton bud in to your cars power steering tank, should be all you need.

Thread: Cross slide adjustment
24/03/2016 17:56:16

John, my lathe is a 14"x40" Taiwanese job around 20 years old. The slide is starting to crumble around where the compound slide locking screws are (the radial portion) Add to that lead screw wear and no more GIB adjustment left even with 0.020" shim glued to one side of the GIB I am hoping to improve things. I have had a casting made and generally beefed things up and also added thickness to put tee slots in. I will let you know the results when finished. Chris.

Ajohnw I am in the process of making a new cross slide to dial out the sloppiness on my lathe. New lead screw and nut to be fitted on completion. I really hope I get the sort of results you show.

Thread: Black 5 Boiler problems
24/03/2016 14:39:38

Ron as a fairly recent board member who does not make models I had not read your post until a couple of days ago.

(My machinery is used for motorcycle stuff) You certainly have gone through the mill with your boiler, what did catch my eye was your location or the location of your SME I am not far away in Kings Bromley. I hope you can move forward at a good pace now you are sorted. Chris.

Thread: Grinding wheel ..balancing hole?
23/03/2016 11:31:28

I spent 50 years in tool making and used thousands of grinding wheels. I never saw one with holes in like that. I would bin it and get another.

Thread: Snapping taps
21/03/2016 19:31:23

When I was in the die making game we did lots of small 16 impression tools. Each piece of H13 or in some cases 420 stainless had 4 M4 holes 15mm deep. That is 64 tapped holes in the die side and another 64 in the punch side.

Lessons learnt, use a 0.1 oversize drill/use tapping past not liquid/ throw the tap away when it starts to bind when you wind it out. I did these by the hundred and rarely broke a tap. Have a look for one of the eclipse flat bar style tap wrenches they give a nicer feel. With the advent of CNC mills we moved on to machine tapping on all sizes down to M4, none of us brave enough to go any smaller !

Thread: Trouble at mill
20/03/2016 10:00:36

Sam, as above a rotary table or if you have one a boring and facing head, even a plain boring head if you mark out and mill close to the lines then bore.

Thread: What Did You Do Today (2016)
19/03/2016 20:10:34

Today I got my pre war bike timed after an engine rebuild and decided to try and start it tomorrow. Spent the rest of the day milling a casting I have had made for a new cross slide for my lathe. A lot beefier than the old one so I can get tee slots in and stronger in the compound slide area where mine is starting to crumble.

Thread: Steel Channel
19/03/2016 20:05:12

Depending on where you are I have plenty of 25x25 box with around a 2 mm wall section.

Thread: Ferrite rings
19/03/2016 09:28:48

Bill is that a Marlin on your avatar ? In my car trial days they always did well on things like the MCC long distance trials. So much more comfort than a Dellow !

Thread: WM16 with big Vice
19/03/2016 09:24:35

Not overkill at all that is a nice vice and yes it does look to be a J&S. I like a vice of that pattern without the more usual two strips to rest your work on. So much easier if setting an angle wedge or little sine bar. Nice find.

Thread: Ferrite rings
18/03/2016 13:26:12

Not many of us use these now so keep an eye on the usual sites for someone selling a complete one.

Thread: Jowitt MkII Popett Valve Engine Build
18/03/2016 09:51:04

Jason, I am not a model maker as pre war motorcycles are my main interest but reading such a common sense clear build log as yours I am tempted to make one. What I like is the lack of chasing accuracy beyond what is required to make it work. When my work load gets down a bit I will make a start. Chris.

Thread: Droop and rein
18/03/2016 07:52:46

I have used many copy mills. Hayes diemaster with hydraulic copying/Cincinati/Various Deckle machines an Alexander copy mill plus a Bridgeport but for me the best was always the Keller for the way the swarf dropped away.

Oh just remembered using a Gorton as well.

Thread: Thread major diameter
18/03/2016 07:46:21

You are doing nothing wrong. It is just the way single point threading works out. You need a shadowgraph to get the point radius/flat correct and being single point you will never crest the major diameter. Go with your file over or buy a full form insert and holder.
