|Thread: Disc drive - Anything useful inside ?|
Powetful magnets albeit odd shapes; tiny bearings, motor might come in useful for something small.
|Thread: Adjustable angle plate|
Nicely done; give that man a woodbine.
|Thread: Back to Imperial|
..I am sure that for foodstuffs it makes little difference as long as you aren’t supplied with 453.6g and charged for 500g'
Are you sure your not; & by the way I've not seen anything on sale with a weight of 453.6g it's always 100g, 450g, 500g, 1kg increments.

|Thread: They see you coming|
Similar experience earlier this year; I purchased a 19 reg Vauxhall Mokka which still had 1 years manuf' warranty left on it, fortunately for me as it turned out. A couple of weeks later I noticed some fluid marks on the drive which I suspected may be brake fluid as it wasn't dark oil type stains. I arranged to have it back in the dealers garage for a check, along with a request to remove a nail from a back tyre & plug repair it. It turned out that the leak was from the aircon compressor.. 2 year old car..? . Fortunately for me the dealer said it was covered by the remaining warranty period so no cost to me, otherwise it would have been £700 fitted.
I asked them to replace two front tyres also as their tread depth was down compared to the rear tyres (inc' the one with the nail in) not beyond the legal limit though, so had decided to make them all equal before winter. As re. the nail, they didn't remove it as they claimed it was too near the sidewall to be a safe repair..?. I ended up taking it to Kwik fit ( usual disclaimer ) who told me the same reason, so ended up paying out for a new tyre albeit the original had virtually full tread depth left on it.
It goes to show that you can get a mix of good & bad advice from dealers & independents.As it was I'd covered all aspects so was happy with the outcome/s. It pays to have a bit of knowledge about mechanics but for those who haven't, it pays to get a second opinion.
|Thread: What Did You Do Today 2021|
Did a bit more on my Scotch yoke engine; didn't have any material of near enough dia. to make eccentric strap so used a piece of larger dia. This gave me the opportunity to use my rotab' which has sat idle for a long time. Marked out strap OD inc. lug for connecting to valve rod, chain drilled through with 3mm drill followed by 4mm slot cutter to leave strap attached by lug. machined lug to dimensions still using the rotab, separated the strap via sawing down ea. side of strap, then finish machine the lug itself, pleased at how it has turned out. Onward & upward as the cliche goes..
Having the connecting lug integral prevented the need to mess about trying to braze a separate piece on.
|Thread: Machine Lamp Recommendation?|
+1 just received one of these lights; throws a very bright beam onto the work area, tried it on my mill ,the difference in luminescence compared to the flexible spot I am using is amazing.
|Thread: What Did You Do Today 2021|
Finally got on with more work on my Scotch yoke engine. Assembled the frame, bearing support, crank shaft, cylinder assembly, & gave it a run with my hand drill, so far so good. Next steps are to make eccentric, eccentric strap, rod, valve, valve chest + covers, strip down ,degrease, paint & have it running on air, not a lot ..
Excuse the video attempt, I haven't put anything up for quite a while & it looks quite sloppy.

|Thread: New Lathe replacement for Myford|
I have a WM250V-F with power X feed, a WM 16 mill with long table, 2012 vintage, both of which have performed more than satisfactorily for my needs. As said space is a deciding factor, & as per SOD I have a single garage conversion & that is quite full as it is, in fact I could do with another garage. If I was looking for another lathe I would take a good look at the WM290 with VFD & factory fitted DRO, along with WM18 & fitted DRO, Myford 254, Harrison M250, larger again, but still ample for model work.
|Thread: Fitting DRO to a mini mill|
Have a look in my album.. DRO. there are some pics of my dro fitted onto my WM 250 VF
|Thread: Bench grinder|
As an aside ; are the bearings on the shaft starting to go, do they 'rumble' when you start the motor up?, it usually is one of the above reasons though.
|Thread: Warco WM180|
My WM250V-F behaves in the same way. I use the red & green buttons to stop/start & the lowest rpm shown when the pot is fully ACW is 59 - 61 rpm. I can set the speed, then can stop/start without having to wind down the pot. I always turn the pot down fully when finished for the day, same with my WM16 mill, once set, as said, I can stop/start without any need to wind the pot down.
|Thread: Moore & Wright Automatic Centre Punch Cat No 280|
The 'other' is in the old town hall, his mother pawned the other so he had no ***** at all
|Thread: Auto sign in?|
I have the same problem as well as keeping things that I type in to the reply box,when I have to move on to another site, or even looking in 'my albums' involves losing all the typing I have done. I have had to resort to highlighting the text then 'copy' 'save' on to a word doc to paste back after I have inserted anything from another source, or copy to clipboard & paste it back. Once I leave the reply box all text disappears that's what I would like to resolve. It only happens on this site !
|Thread: Carbide inserts confusion|
Not detracting from or disparaging Warco's or other uk sellers have a look on Ali express or Bangood web sites where you can find various sizes to suit your lathe, & can usually be sold with a box of ten inserts for a very economical price. Usual disclaimer applies.
|Thread: Moving machines|
As mentioned in previous posts +1 for the engine hoist. When I was setting up my man cave I bought the 1 ton hoist from Machine Mart + a 1 ton web sling as there was a discount offer on at the time. It was eminently suitable to set up my lathe ( WM250V-F) onto its stand & the mill WM16 onto its stand, with the assistance of SWMBO. Usual disclaimer applies.
As it folds up I have it tucked away in a corner for future ( ? ) use.

|Thread: Pulley size help required.|
FYI ... calcs to work out your driver pulley to give you the req'd final speed...
Scanned from my Newnes Mech.Eng. pocket book.
|Thread: Elmers No42 Engine|
Nice as is, no need for paint, well done Barry.
|Thread: What lathe pointers|
Would second JS's listing for my likes, otherwise a nice Harrison M250/300 will do nicely.
