Thread: How To Post Pictures/Photographs and Create Albums

I seem to have success with sizing my pics at 300 - 350 wide when posting, the height adjusts itself automatically, or viky verky...

File it; if CI it will produce grey dust.


Thread: Breaking drive belts on super mini

Obvious questions but; have you got the tool on centre height, do you have enough back rake on your tip ( HSS ? ) so that the swarf 'curls' up & out of the slot. you say you have paraffin as coolant, are you parting off aluminium in which case you need to up your rpm as 350 rpm will heat up the aluminium & make it stick. Not having a mini lathe ( I have a WM250V-F ) I assume that there is no auto X feed & you are feeing in by hand, can you 'feel' what the tip is doing, you should be able to 'feel if you are feeding in too fast / slow... adjust accordingly.

I have my compound slide pulled back toward the centre of the X slide so to have better support under the overhang & with all the locking bolts on the saddle pulled up, as you have, plus I have a lock on the gib strip...

Tool holder / compound slide set back so that overhang is better supported over saddle...

FWIW... if you have a BBQ that you are not using, light it up & get the charcoal embers to the usual white ash stage, place your casting in the middle of the embers & leave overnight to cool off, that usually does the trick.

Continued on with my Boxer twin oscillator; soldered on the end blocks after re-tinning the frame & blocks, didn't want to redo... again! seems to have taken ok, got down to cleaning it up... plenty of elbow grease coming up !...

Very nice work, nice video, I do like the little shaper he has.


Thread: Warco WM250 Colle set question 2
15/11/2018 12:06:59
Posted by Howard Lewis on 14/11/2018 22:28:25:


Agree with S O D comments. 3 jaw for most work; 4 jaw for accurate centering.

Although have the equipment, rarely use my ER collets in the lathe . (Useful if doing repetition work, but not my scene. Biggest quantity ever made; eight clamp screws for a 4 way toolpost)

Made a holder for ER25 collets for a Tailstock sliding Tap Holder.

BUT most often used on the Mill, to deal with different size endmills / slot drills, arbors for gear cutting, or for work holding, in Stevenson type collet blocks, or the Rotary Table.


Virtually the same as I do apart from the tailstock holder which I have made a different type. I use my hexagonal Stephenson's block in my three jaw chuck for small work as I can get it to run more accurately than the small amount of run out the 3 jaw has. I also have a MT4 collet chuck to fit the headstock taper & find that this suffices more than adequately for my needs rather than buy a collet chuck & back plate, so I am well catered for.


Thread: Upgrade from SC3 lathe

…. 'I am surprised there are no Warco owners praising their machines. They did look to be well built'

I have a WM250VF + a WM16 mill & am highly satisfied with both machines to date... both bought from the Harrogate mod' exhib' back in 2012. They both do what I give them to do without complaint, mind you I know their limitations so don't flog 'em.

Happy now … devil

Thread: Myford ml7 tools size
13/11/2018 11:30:32

Have you considered getting a tangential tool; initially expensive but you only need one HSS tool bit, & will only need to grind the top face to touch up plus you can set the bit to centre height without having to shim up. There are other members who have made one for their machine & swear by it, & have drawings available if you ask. I have one, bought from Eccentric Engineering, ad on the right, usual disclaimer, & I use it for 90% of my machining. I do have a selection of HSS & indexible tipped cutters but these were bought 'along the way' as we all tend to do.


Thread: Do you clean up your rough end

Posted by Ian S C on 13/11/2018 10:02:53:

You might as well do it while it's still in the lathe, you'll have to do it at the beginning of the next job, and that time might be wasted, it's going to happen some time.

+1 - I tend to face off the end & put a light chamfer on... then ready to spot / centre drill on next job.

It is a LED ring that attaches via magnets to the bottom of the milling head, around the spindle. I bought it on eBay but to be honest I am going to replace it with a larger diameter ring. This ring has an internal diameter which is 2mm larger than the spindle thickness and so the light is concentrated around the spindle. A collet/drill chuck or shell mill actually blocks the light from getting to the cutting surface.

I am going to get a larger one with a 100mm diameter (€8 on Banggood) to see whether it clears the tool. Keep you posted.


Much appreciated. My mill measured up at 80 mill but 100 mm looks a more promising size.


07/11/2018 13:49:12

Looking good Mark; I like the lighting set up on your mill, I assume it's an 'angel eye' off eBay. is it powered off a 12v 'wall wart'? would be nice to see more pics of lighting set up.


Thread: Help with Clarke CL500M Milling Aluminium
06/11/2018 09:25:13

Some info for you, FWIW, sorry not very clear but readable; It will give you the general set up for depths / widths of cut etc. Aluminium can differ in content, some are 'soft' others 'hard' so surface speed differs & is adjusted accordingly but if you are above 800+ rpm you'll be in the ball park. Air mist blast coolant / WD40 are the better methods of cooling especially if you have 'soft' aluminium material, helps stop it 'sticking' to the teeth tips.

Thread: Beginners Engine Advice?
03/11/2018 00:00:34

An ambitious plan to start with; have you got equipment, lathe, mill, / drill, measuring equipment, workshop / space etc, etc, when was the last time you used any of these ?, I hazard a guess that was in college or uni & your engineering background is in CAD designing etc as you claim not in any mechanical way. Not to worry, there are many superb models that have been made by non engineering back ground hobbyists.

A) nothing is a step too far... it's taking that first step.

B) There are always options... what is achievable with your present capabilities.

C) I would suggest you start with a smaller model i.e. as you say a Pottymill, Stuart type kit, 10V, etc. to get some practical experience first & to get to know your machinery.

D) We're all mad on here so join the gang... smile p

As you have already bought a set of plans you've made a start. you need to ask yourself some questions though, do I have the capability to solder up a boiler to meet inspection / certification / insurance standards ?, can I form sheet metal, can I bend / solder tubing without kinking it ?, Can I make a clack valve / safety valve ( although these can be bought ) etc, etc.

I have a set of plans for a 'Minnie' but loco's are not my bent … at the moment! ( I don't know if I'll have the time to finish it ), I am sticking with smaller engines at the mo', the likes of Stuart 10V, 10H, progress, oscillators from plans from 'Elmer engines' etc. to which I can make mistakes without too much cost to material, time etc. & where I can get satisfaction of seeing them run ( albeit on compressed air ) in a reasonable time scale. You also have to factor in ongoing tooling costs that have to be approved by the finance director...SWMBO ! … don't be under the misapprehension that brownie points will get you every thing you want / need, ... it doesn't work, believe me! devil it only takes one 'Aw sh1t' to wipe out any you have accumulated.

Never the less if you feel like starting off with a loco; go for it, you wont know if you can do it until you try. I'm sure that there will be other members who will offer their opinions & advice, the above is just my offering. One thing is for sure; once you're hooked, you're hooked.
