Thread: Bench Grinder
15/01/2018 15:43:25

I have a Hilka 6" bench grinder. It has a 1/2 HP motor and is just the job for regular workshop use. The tool rests could be improved but I don't usually use them at all anyway. Colin

Thread: battery problems
13/01/2018 16:01:09

I generally use a very light smear of any available grease. Colin

Hello David and welcome,

I find these early workshops fascinating Colin

Thread: Starrett Tool Makers Steel Clamps
18/12/2017 19:13:01

I have a vice which is similar to the Starrett one which was made for use on a surface grinder and is very accurately ground all over. Colin

Thread: Any uses for damaged cutters?
18/12/2017 19:05:39

I have several side and face milling cutters with missing teeth and experience shows that they work perfectly well on thick material but you need to take more cars if the material is thin because one of the teeth will be taking twice the cut on auto feed. Colin

Thread: Steel plate distorting when machining surface
18/12/2017 18:55:48

The problem of long machined strips warping occurred on almost every job I had to do on press tool stripper plates. When the clamping was released after machining the bar could be guaranteed to bend so I always had to use a fly press to straighten them after machining. This is a tricky operation too although this item doesn't usually have to be machined on the reverse side. Colin

Thread: EN32B Steel
18/12/2017 13:10:25

I machined EN32 for many years using HSS tools and never had any problems. Is it anything to do with imported steel? I wonder. Colin

I have owned an old flat belt horizontal mill for about 50 years and all that time intended to get the power feed working and make the other bits to go with it; trips and disengaging mechanism . Now I've done it ! The machine was retrieved from a scrap metal merchant in pieces all that time ago. Colin

You can't leave the story at that! Unless you want to write it up for MEW, that is...

hmm.............That might be interesting...............??.....It's a long time since all my previous articles and now we are bogged down in new technology............ Colin

I have still got a lot to learn about posting and at the moment I can't see how to insert another's post, as a reference, into mine. Colin

Colin

Just under your message use "Quote".

The gotcha is that you have to line- feed / new line / down arrow or whatever, to get rid of the line down the side of the quoted text. If not done your new text looks as if its part of that quoted.

Pete

Thank you Spurry.

Thread: Why Brake
05/12/2017 15:46:55

There used to be a van with windows called a shooting brake; Is it something to do with multi purpose? Colin

Thread: Use the lathe or the mill
05/12/2017 15:42:57

The lathe is very good at this sort of work, is faster than the mill and uses cheaper tools. I often use the lathe in this way. Colin

Thread: Elliot 10 inch shaper motor pulley
05/12/2017 15:33:41

The 3 phase motor on mine (which I modified to run on single phase) is/was slower than Brian's at a rated about 960 rpm and the nine and seven sixteenths diameter big pulley takes a vee belt16 mm wide at it's widest. Colin

Thread: Why ACME threads on leadscrews?
03/12/2017 19:52:13

Acme threads facilitate engagement of half-nuts of the rotating leadscrew. Colin

Thread: Dros without breaking the bank?
03/12/2017 19:07:08

never find it necessary to use flooded coolant on my minimill I just use a brush with cutting oil where necessary. It is a good idea to cover the cheap DRO with plastic or metal angle though. Colin                                                           Oops ,absent mindedly entered twice

It is a very quick operation to remove and replace the button cells on the cheap DRO if it is not to be in use for a while. I have used mine for about 8 years and had two failures which I repaired by dismantling the reader and VERY THOROUGH cleaning of the circuit boards and metal parts.They both worked properly on reassembly. Removing the button cell when not in use gives you a chance to avoid the corrosion which can be caused by a dead cell . As Neil has pointed out replacement readers are not expensive anyway. It is necessary to keep the reader clean and I try to achieve this by tucking a piece of stiff folded paper in the form of an angle over mine. Colin

Thread: Drill out a ht c/s allen screw
21/11/2017 16:45:04

You can drill HT screws with a HSS drill provided you keep the drill sharp, don't let it rub and use a slow speed.Colin

Thread: Heavy item for use in fidget spinner.

New pound coins will make them happy. Colin
