|Thread: MT4.5 sleeve|
Your rotational speed will need to be at the lower end of your suggested range- say 40-100 rpm. Between centres is OK. Don't forget to have the work rotating the opposite way to the wheel. Even if I was doing this on a proper cylindrical grinder in the days when it earned me a crust ,I would not dream of doing it without flood coolant.
Rather than go to all that trouble, have you thought of using a carbide tool and just turning it down - its how I would do it! Good luck anyway.

Bob this should help.
|Thread: Lathe bed regrinding|
Hello Barnabas - You may not to tie yourself down to grinding alone - my ancient Grayson flat bed was flycut on a SIP jig borer many years ago. It made a lovely job of it! I would add that the bed was close grained cast iron and unhardened. The bloke who did it for me said it was the best cast iron he had ever machined.

My wife agrees with her . Enjoy yourself Martin.
|Thread: WARCO spindle bore|
I used to own a WARCO WM-250 v-f lathe (the older non-inverter version) which I moved on some time ago. I was just going through some bits I had made for it and noticed that my shop made spindle stop for it is 28mm diameter. Out of curiosity I googled aforementioned spindle bore dia. but everything that came up for all variations of the WM-250 that I could find returned 26mm - without exception!
I had used the stop many times so I know I am not dreaming.
|Thread: Curious coating|
Some time ago I bought at auction a large amount of machined and part machined components that had come from a manufacturer of conveyor lines. Much of the stuff was in the form of stainless and aluminium rollers. To date this lot has come in quite handy as a store of material.
Yesterday, I fished out a piece to turn into a stub mandrel for facing of a pair of steam cylinders. You can see from the pic what happened to the tool tip when I tried facing the grey coated shoulder at the now shiny end of this aluminium like material.
As I fed the tool in using a light cut the tip glowed orange /red. I should mention that the tool bit is not bogstandard HSS but something much tougher and harder – I forget the trade name for it. The coating is so incredibly hard that a file just slides over it without leaving a mark. My guess is that it might be ceramic anti-scuff. I finished machining by using a carbide insert without further problem.
Also, the aluminium like material was much tougher to machine than any “aly like” material I have machined in the past. I wondered if it was titanium but I did a google and read that titanium swarf will burn with a bright light similar to magnesium. It didn’t – it just glowed orange.
If anyone can shed light on coating and/or material I would be very interested to read your comments.

|Thread: New coffee maker - disgusting taste!|
They had stopped using bromide in service tea by the time I joined as a regular in 1964. I know it was never used in our cookhouse. The tea still tasted foul though because they used tinned evaporated milk instead of fresh milk - uuuccckkk !!
We often had to brew our own tea when away from the barracks and here I was introduced to Fussels condensed milk which had a much more acceptable taste in tea provided you could stomach the sweetness.
I cannot get going properly in the morn without tea. I use a tea bag and brew with cheapo bottled supermarket water (about 17p for 2 litres - our tap water is foul) in a pre warmed mug with a lid (saucer) on top.
I wrap a tea towel (its where the name came from - did you know that?), round the mug for insulation and infuse for exactly seven minutes - I have a timer on my desk for that sole purpose. I season my brew with a third of a teaspoon of unpasteurised acacia honey and a splash of semi skimmed and sit at my desk to enjoy reading the latest posts on this forum.
I like to start the day with tea and then drink alcohol.
|Thread: bunging up hole in CI|
I have this problem fast approaching but I intend using JB weld to fill the 'oles. I am also going to experiment using high build primer on the castings to - hopefully - smooth out some of the imperfections on some of the castings.

|Thread: Alternative materials|
Brass it is then chaps. I like the idea of cast iron and steel but I'll go with brass on the basis that it is one thing less to rust on the engine. Thanks for your comments.
I'll soon be ready to machine a pair of eccentrics for my ongoing build. The two gunmetal castings are missing from the set of second hand castings I bought. I could order a pair from Reeves or alternatively machine the eccentrics (which wrap around a 1" dia. sheave) from some 1/4" thick brass plate I just happen to have.
I am reasonably certain that the brass should be OK but what will the judges think?
|Thread: Cheap 3D printers|
I bought one of the ALDI Balco 3d printers a few weeks back. It was brain dead on arrival - would not power up. After customer support led trouble shooting they advised that the power supply must be dead. Unit was returned and full refund issued without a problem.
A week after I returned it I noticed they had reduced them by £50 to £250 but now I see they are back up to £300 again.

|Thread: Hi from dorset|
Times like this make me wish we still had our caravan at Bowleaze Cove so I could join in! Welcome Phil.
|Thread: What Did You Do Today 2019|
Just back from a short trip to our local Emmaus to check for anything interesting bookwise. Bought a book titled "British Steam Engines" and another on the history of Sywell aerodrome.
I could not help admiring the lovely German made grandfather clock they had which chimes beautifully on the quarter, half and the hour and has moving moons.
So I bought that as well.
Got home and realised we had forgotten the milk.
|Thread: Where to begin?|
Dave - At 72 I am not looking for a job CAD/CAMish but if were I would have read your post with great interest. Very informative and well constructed - well done!
|Thread: Digi ME MEW not working|
I'm not to hot on android technicals but the ME and MEW apps suddenly no longer work on my tablet. If I finger click on the two icons I just get a spinning circle. All seems OK on my phone - they work OK.
I am reluctant to uninstall both apps and re-install as it will probably mean I will have to go through that tedious procedure of downloading all the magazines again. Am I missing something?
|Thread: Skyhooks - an overhead solution|
Anyone who suffers the "nuisance" of magnetised tools in their workshop obviously does not have one of these:
This example lives under a bench but is rarely used.
Like Mike P though I also appreciate the benefits of magnetic screwdriver tips. With my shaky mitts it often makes things so much easier for me. For this reason ALL my screw driver tips are magnetic. For non-ferrous fixtures I use a dollop of blutack - does the same job!
I find it very trying looking for a particular hand tool which has hidden itself from view and with no wall space left to mount tool racks the tools remained in cluttered drawers.
So I eyed up these magnetic strips in either LIDL or ALDI (I can't remember which) and thought they might come in handy. The only vacant space to speak of in my workshop is the ceiling so that is where I fixed'em. My screwdrivers and nut runners now have a new organized home. It still does not stop me scratching my head though when I glance up and spot a gap and wonder where I left THAT one!
Initially I had thought the magnets might not be strong enough for the job but these "skyhooks" are well up to the job and in the two months or so since they have been up there nothing has fallen of.
|Thread: Metal cutting bandsaw|
To save on space (of which I have little left) I tuck my WARCO CY-90 band saw between the end of a bench and one of the lathes. I shortened the 4 legs by 3” and fitted castors so it can be swung out when needed.
