Thread: Maintenance and setup checking my mill
21/03/2023 04:45:17

The 2x bolts on my mill is in addittion, its not part of the setting or clamping surface where the shimming happens, so it should not interfere with the stiffness, most it should be checked at each height of operation of milling I would say.

My mill is also "leaning" a bit as delivered, however it has two bolts you can force the head(Upwards) vertical using a measuring instrument as reference to check what you are doing. The distrubutersalesman was surprised to see it when I showed hin in person, seeing their latest ones and other does not have this ability of adjustment without adding shims(Resonable way of course). The additional question for me is why was it shipped this was, does tool pressure plays a role in decission-?

My expeience with "Plus Failities" was that after everybody has tried everything one can normally try, ask a specialist at company to cancel your phone number setup completely and re-create it on the system as it was, sometimes some sw links get lost and cannot be restored with normal configurations or manipulations.
Martin has a good point.
NoteI stumbled on this method after some months of few isolated cases not solved with normal ways, which included all sorts of system configurations)

Thread: Workshop Mistakes (True Confessions)
11/03/2023 03:12:32

The type of mistake that frustrated me the most is where I have to mill on project from both sides at angles and became sloppy(impatient one should never be) and milled it wrong in the twist of things.

Thread: Q: Is this progress …
03/03/2023 22:14:32

When I see these type of suggestions, I alway wonder how long it will take before all is over and at which uptake it could happen.

Thread: Why is the world of model engineering still imperial?
03/03/2023 22:09:38

From a practical and cost savings and resuable part sizes perspective what is your opinion on imperial versus metric engineering uses. Does metric lead to parts looks similar but just not the same in measurements in comparaison to imperial. I always wondered about this.

Thread: I broke my own rule
20/02/2023 14:57:49

I fitted adjustable pressurevalves with guage and watertraps, so just adjust pressure way down, but mostly don,t use iT. Light swarf flies away.

Thread: non-standard insert?
18/02/2023 20:56:24

How does the toolholder looks, pos, neutral, negative-?

One can add a shim(s)(Determine thickness to change angle at insert tip when cutting) to rear of toolholder temporarly and tighten to see if it cuts better at a steeper angle, I did that and then increased the angle from 5-7 degrees and cut toolholder in mill to achieve that for toolholder.

Thread: Cant seem to get a nice finish
18/02/2023 20:48:23

What happens to the pattern if you recut it without any adjustments-?(Few times-?)

Thread: Lathe and mill covers
17/02/2023 03:07:16

I am using motorcycle cover for lathe, must still get one for mill.

Thread: Headband magnifier - blessed relief!
16/02/2023 00:05:23

I have optivisor nr 3&4 and one day dog got something in eye, at vet I decided to mention to him about these optivisors, I went home got them, he used it was so impressed they borrowed it for two days to confirm and ordered for them new ones to use. THe glasses are very good and made to use with your own glasses on.
The only drawback is safety glasses with it, but I am sure one can add a face shield modified one or ther way if need be.

Thread: How close have you got to a Darwin Award?
12/02/2023 02:18:07

We lived in a town up the hill then down to main street and up the next hill to high school. One afternoon I decided to help myself with my fathers Hudson pickup of 1947 to attend a woodwork class. My father was asleep, he was a steam locomotive machinist as they called them and worked any hours.
As I go down the hill towards the only robot in town, there was a VW beetle at the stop red robot. Getting closer I pushed the brake, and then -nothing-, I completely forgot about the handbrake, and steered the Hudson like you suppose to fly a plane till it strikes ground, past the VW and pavement right over the road, luckilly a car just passed up the hill till the Hudson stopped.
I turned around and slowly drive back without brakes to home. Long story short, the brakefluid pipe weared through on the engine block/ sump beneath. My mother helped me replacing the pipe, bleed the brakes and when my father went to work, the Hudson was going again. It could have been him on a different route to work and a real accident, I was just lucky. About a week later he was informed, he was surprised and impressed with the repair. The Hudson could have flattened the VW Beatle, I know because you can stand on the mudguards and lft the engine. My father had a Hudson car 1941 as well, bought this pickup on a nearby town for 10 dollar and repared it, h used it mainly to drive to work about 3 Km's away every day. That was then.
So far I was lucky to have an car accident free life not to say it cannot happen.
I still clearly remember it today.

Thread: Carbide end mills in a hobby machine? your experiences please.
07/02/2023 21:43:59

I bought HSS(2x flute) and 2x carbide 4x flute endmill sets. I milled a lot lately and am so impressed with the carbide endmills(Have not touched the 2nd set), found the 10mm & 12mm very usefull, used the 12mm the most.
Have not break one so far even the 4mm.
I was surprised how long they last, and the ones I got alliminium don't weld to it, unlike whats happenning on the lathe.

Thread: What did you do today? 2023
29/01/2023 23:01:24

Did some small woodwork(It seems to like climb milling where possible(10mm4FL carbide endmill) on my mill to make swarf containers for vice using disk magnets & parts of face shields cut, face shields are cheap and cut well with a scissor to size wanted.

QUOTE Spiral Point NO this will fill your hole with swarf or better spiral flute - Yes much better

It's a through hole Kwil wink

Horrible stuff as everyone says - a larger hole than that usually dictated and use paraffin (kerosene) rather than WD40 - much better than anything on ali at any time. Plus Gas is good too but difficult to find these days I would think.

If it's as gummy as you say though you may well have to think of an alternative

Best - Tug

I was thinking very thin fluid. I scrapped a old Dell laptop yesterday to get the disk magnet, it had a sizebe heatsink, will try a few fluids on that, starting with WD40, then Fuchs, then try other.

29/01/2023 04:32:29

I would try water & dishwashing soap mix.

Thread: Angle grinder stand usage

Hi Chris, the instructions that came with mine says the adjustments should be made to put the centre of the disc over the centre of the workpiece. As JasonB has pointed out, the disc will cut in a slight arc, which will be away from the operator. If you have it behind the centre of your workpiece, it will have the tendency for the forces at the start of the cut to put the load more onto the movable jaw, which you should not do. Starting with the disc on centre will give an equal pressure to the centre of the work and most of the force will be down into the base and once the cut has started, providing it is adequately held, should not have any tendency to roll or flip-up and the cutting forces will be shared mostly by the base and the fixed jaw. If the workpiece is not adequately held, the disc will have the tendency to roll or flip the workpiece in the front, behind or on centre, but if it is behind, the chances are it will roll or flip-up the workpiece and out towards the operator.

Regards Nick.

Thats how I have it currently, I made T-Nut strips, then cut off the lenghts.
When I had a new blade on(The thin ones) initially it cut like butter. Then after I made the covers and use it further I find that a certain amount of constant pressure cute very good, as appose to too light pressure it glaze the metal and dont cut well, as well as you put too much pressure, its a 750Watt angle grinder.

Seeing a spring is not linear I was thinking removing its own retrack spring, add the correct weight to apply the correct pressure for a good cut, then use a safety trip switch with reset like a horizontal saw going down.

Hi, I once baught a 2nd had anglegrinder stand, and this weekend decided to put it in use and realy like it doing small stuff cuts. I also made it spark proof with covers, so no more waste over the shop.

My question now is, what do you suggest is on how to position the grinder disc wheel centre over the work to cut:
1-Before centre of work-?
2-On centre of work-?
3-Over centre of work-?

Which is the way to go, I could not find the answer I am looking for on Google.
