Thread: Hemmingway/Machin gearbox label
19/06/2022 16:27:11

Can anyone assist, i need to make new charts/labels for a Myford ML7 gearbox, the old ones have disintegrated due to oil contamination and are illegible.

The gearbox is i believe a Hemmingway/Machin gearbox, made from plans and castings.6e545621-4111-4a5b-bace-0957b57d7c84.jpeg

Thread: Grease in oil lines

Hi what mill is it as some mill's use grease on some parts like a Bridgport uses a white grease for varidrive bitts.

David

It’s an Aciera F4 David, fortunately it came with a manual, including a lubrication schedule, which previous owner obviously didn’t bother reading !

And to answer Swarf Mostly’s question. Fortunately the ways seem to be in A1 condition, so no harm done either way.

Picked up a new to me mill at the weekend, seller proudly mentioned he had greased all the nipples to save me the trouble……yep he’s greased all the oil nipples to the ways. So whats the best thing to do, thought about pumping some diesel through to flush the grease out, followed by the correct way oil……..thoughts on a postcard ?

Ah ok, followed your link to the Femi saga........surely that is a courier issue rather than a faulty saw ?

Femi NG120 ABS bandsaw is one of the best workshop investments iv’e ever made, never had a minutes bother with it, cuts clean and square every time, no matter what the material being cut. Makes all those generic Chinese clones look like junk......and i had several different flavours of them before the Femi.

Am interested to hear why you sent yours back OP ?

I'd be a bit wary of having that tractor on my nice blockwork patio too.

regards Martin

Tractor didn’t cause any issues, but the concrete waggon a few years prior did. chucked some boards down to spread the load, but the tight turn through the gates did some damage.

Am always a bit suspicious of engine cranes, a lot claim to be capable of lifting 2 tonnes......yeah right.

I bought a commercial vehicle one for peanuts, no one wanted it because it was stupidly huge. Rating fully closed 2800kg, and fully extended 800kg. The thing is seriously beefy
Donated it to a pal who cut it up and attached it to the back of his tractor. To give a sense of scale the mill in the pic has a 56” bed, and the tractor is approaching 6 tonne

Advice to the OP would be don’t bother, if you need something heavier duty, just buy one,no point compromising safety.

Thread: Yet another scam lathe sale on ebay to be aware of

Lol, that's my lathe I bought recently, definitely a scam

30th of October to be precise.......nice buy that yes

There is no one stupid enough to buy a lathe sight unseen is there & then pay BACS?? Hold on my brother in law who is not stupid purchased a tractor just like that & guess what it didn't exist!

Tony

Have sold a couple of lathes that way, and a milling machine, which was bought by a very nice man in Malta.

Not everyone is a scammer, but personally i always collect with cash, money is too hard earned to gamble with.

Using one tooth instead of three is the same effect as upping the feed by a factor of three. Maybe you should have tried a faster feed than you were using.

PS if there is a runout error of maybe 0.002" from the highest to the lowest insert then the 400rpm and 1" per minute feed will result in only one tooth cutting, one possibly rubbing and one not doing anything apart from sweeping away debris.

Agree with the above, using one insert pretty much puts you back to using a fly cutter, but should rule out any issues with the arbor/body alignment. On the cheapo i had, the triangular inserts were so far out from each other it was never going to cut correctly, you could see the differences by eye. Plus the actual insert angle looked wrong.

30/12/2020 09:08:41

Have you got a link to the tool, or a photo ? Asking because i bought a cheap 3 insert face mill once (Not from Arc) and it was useless, could never get a decent cut from it, and my mill is industrial sized.

Try running it with one insert and see if that makes any difference.

Thread: How surface hard does plasma cutting make steel?
16/12/2020 20:44:32

At the end of the day, plasma cutting and flame cutting etc are industrial processes, presumably expected to be machining with industrial sized machinery, which of course wouldn’t bat an eylid at a bit of a hardened skin. So not the suppliers fault in any way. Best way to get through it for a hobbyist would be to hit it with an angle grinder before attempting turning. As for the blow hole, just order a slightly oversized disc.

Sorry to break it to you, but classed as ‘immediately dangerous’ in the trade. Any attempt at repair would be a bodge. My advice is don’t use it, sell a kidney or whatever it takes and get a new one.

No need to worry about charging points in flats, terraced streets etc, once they introduce charge per mile motoring, only the well heeled will be able to afford to run a car anyway.

Just get a 125mm discs angle grinder, which cuts everything

I use blue spot 1mm stainless discs

Aldi may still have a few left in their stores, their online stock sold out fast

Not so good on Ally

Second what Frances said, also bloody noisy, so earmuffs a faceshield, hat and scarf necessary in a confined space.

Got one here you can have for nothing if you can pick it up or arrange collection

Just one point-- They are not normally circular holes but hexagonal. That gives flat surfaces for the weld at the new meeting point.

.

I suppose that would depend upon one’s definitions of ‘they’ and ‘normally’

As I mentioned yesterday:

Here’s an interesting page:

The example you refer to with circular holes is not what I was referring to. If one wants to put a cut along the web of a beam then separate the 2 halves & offset & then re weld to form a deeper castellated beam one needs an edge to weld to. If the line was a wavey one the meeting points would not meet in a way which could be suitably welded & the holes would NOT be circular. Standard castellated beams cut from a simple I beam would be cut such that the line has flat edges for the weld. The hexagonal hole thus remaining would still leave room for services & I do not recall having difficulty installing them. I did fit quite a few tonnes of the stuff in a number of new schools halls etc But I do confess, that was 40 years ago & things move on, so If I am wrong then I stand corrected

The example in the one in the link would , presumably, be cut from an I beam with considerable waste.

Less waste than you might think when you look at the cunning way they are made with modern CNC cutting gear.

celbeam.jpg

I think castellated beams traditionally had hexagonal holes, because they were hand burned using an oxy acetylene torch. Straight lines are easier to burn by hand than circles. They bend like bananas when cut, we used to tack them together in a jig using metal wedges to straighten the halves back up.

No issues whatsoever in the workshop except welding with a head shield, and if you need to get really close to something in an awkward spot, like working on a car.
