Thread: Strimmer /BrushCutter any recommendations ?

Yes modern petrol is a right PITA as far as rotavators & strimmers are concerned.

I have a Ryobi & it’s been Ok ish for about 15 years, when it lets me down next time I will try a Stihl, they are meant to be the best 🤔 I’m thinking an electric/battery one may not have the guts for brush cutting?

Correct me if I'm wrong, but weren't the Myford milling machines imported from far east and 'fettled' by Myford?

That one in the link doesn't look to have fine downfeed on quill, which limits it's usefulness a bit.

And you will want a DRO, they make it so much easier. Hands up who hasn't lost count when doing a long traverse

Yes the 'Myford' mills were made in Taiwan & fettled in Nottingham with decent electrics etc. Mine is a decent bit of kit & a DRO is so so useful!!! A lack of fine feed on the quill is not really an issue, when I did this sort of thing on our Toolroom Bridgeport mill I would drill with the quill & put cuts on using the knee.

The Myford looks a good buy & comes with power feed [not fitted], as always condition, condition, condition is the most important factor! I bought a Myford VME some 15 years ago nearly new for £1500 & fitted a VFD, DRO & power feed, I'm very pleased with it.

You are also only just 'skimming' the cold rolled bar stock. I have seen this effect on 3 phase lathes as well so not sure it's the motor?

2 mins isn't long enough for annealing, I believe hot sand has been mentioned as a way of slowing the cooling?

Farnell UK do them, but £16 odd delivery, you need the exact hole centres so the board fits straight on.

Not all are educated or useful.

From my personal experience you are correct, as in all walks of life the NHS has very good, good, lazy & dire people in it's ranks. It's the best we have got but not perfect.

My first hit with searching 'DTI universal clamp' came up with a 1/4" x 3/8" size from MSC, should be no problem matching one to your particular needs?

Easy 2 dodge, just answer the callers that u recognise;relatives,friends,club members and ignore the rest

Not practical if you are locked into the 'new' NHS system, I get loads of calls from unknown numbers.

What do you mean by 'exact' diameter?

Thread: Best choice of material
11/06/2021 19:21:07

I made a solid block to replace my topslide on a new Warco 290V & really didn't get on with it so I completely re-machined the existing top slide, with a slightly thicker gib strip which was doweled in position. The lathe will now handle any cut I can safely take with no problem.

I used to find on £100K plus CNC machines they wouldn't move by .001 mm steps so don't stress about it.

Seems to me that most run a 40-1 final drive but how do I work out what the missing gear is.

I take it there is a mathematical formula for such ?

I will add some photos later.

Edited By Me. on 08/06/2021 15:35:27

Not all run a 40:1 ratio.

Thread: drilling a bearing ball

Even if you manage to drill a hole thru the bearing ball and glue it onto the turned body, how concentric will it be to the body ?

Drilling a hole is not an accurate machining operation and attempting to do this on very small parts is even more difficult. (1/8"-1/4" diameter ball)

If the probe is used for measuring it's better to turn everything in one operation for accuracy. Use a ball turning attachment if if you want a better sphere.

Paul.

I can't see that concentricity is relevant with this application?
