Thread: An unpleasant nocturnal experience.
11/01/2022 06:01:30

We had a rat for around 2 months when we first moved in to our house that was undergoing renovation. I set up cameras to record its movements at night and to see if it was still in the house. We were very careful to make sure food was shut away and no scraps left out. They are very clever creatures that can fit through small holes, jump very high and climb rough vertical faces.

I decided to block all holes into the house as I found some nights it was leaving and coming back and I didn't want it breeding or bringing others in. Then I set up around 8 or so snap traps (top tip, bait has to be stuck down with something sticky, chocolate spread or peanut butter, because one night I filmed it pulling a biscuit off a trap without activating it) it is then just a waiting game as they can go a long time without food or water. In the mean time I knew someone with rabbiting ferrets but they couldn't sniff it out.

Eventually hunger got the better of it and it got caught in a trap. Still to this day I don't know where it was hiding in the day, I suspect under the floor somewhere but who knows. Not a very pleasant experience but satisfying when finally caught and knowing it was gone.

I would imagine it's catenary wire, used to carry electrical cables overhead between buildings. Not much use for that application without the clamps and anchors.

I've really got to cut back on this kids' stuff and get back to Real Model Engineering... laugh

On the contrary, I'm inspired by what you have made as I am looking for ideas of things I could build for my son for Christmas and would be interested to see/hear about what else you have built

Thread: Collets for Myford tailstock
23/10/2021 03:54:08

Power tapping on the lathe doesn't require collets to hold the taps. I use a drill chuck to hold the taps, snug it down nice and tight and it will hold the tap no problem. The added benefit of using a drill chuck is that if your tapping a blind hole or the tap binds up for whatever reason then the tap should spin in the chuck rather than snap which would be the likely outcome if held in a collet. A keyed chuck is preferred over a keyless as there can be some issues backing the tap out in reverse because the chuck can undo its self, may not be an issue on a myford with a screw spindle nose as running in reverse is best avoided.

Sorry to deviate from the original question I just wanted to offer another option incase you were unaware.

Hope that helps

Thread: Excel Multi Mill looking for information

Didn't consider that to be honest, great idea, I will give them an email tomorrow.

I guess it would have been up against the likes of the VMC, but with the added costs associated with the horizontal side made it not as desirable? Who knows but as long as it turns out as good as it appears then I will be happy

05/09/2021 08:01:41

Thats what I was thinking Baz, there are a few minor issues to iron out but once they are it should be a nice machine. Obviously though from the lack of replies here and lack of information online then they clearly didn't make/sell many of them, hopefully the reason for this would be they were too expensive rather than not very good.

Because of the Covid restrictions, all of the planned engine rallies have been cancelled and I needed to let off a bit of steam with a couple of laps around the local neighbourhood

Please excuse the low quality eBay pictures but I have just purchased this machine and had to partially dismantle it to get it home so until it's back together it's the best I have got at the moment.

I took a bit of a punt on this machine on eBay as the pictures/description were poor but I also couldn't find any information online about this machine, I was able to find only 1 average image online.

So was wondering if any of the members have seen or own one of these machines before? What little I know about it so far are that it is made in Taiwan in 1981, has a int/iso 30 taper in both the vertical and horizontal spindles. It does have an "Alpine" sticker on one of the belt covers as well as the Excel tag on the machine. The turret is swung through 180 degrees to switch between vertical and horizontal mode. The vertical head has a quill that is currently seized (I believe the clamp is just rusted in he locked position). It does have a knee actuated by a handwheel underneath the table.

If anybody has any information or experience of these machines I would be interested to hear as it appears to be quite a versatile machine that is quite stout for its size but I was surprised to find no information online about it.

Thanks, Craig

Thread: Knurling tool
04/08/2021 19:07:57
Posted by Steviegtr on 04/08/2021 16:06:29:

The one i have is very hard to tension the jaws. The ratio is not great. Also the tensioner is very near the rotating work & bothers me a tad when tensioning because of the effort needed to turn it. The Meek design caught my eye with the tensioner at the back.

I'm assuming you are trying to apply tension with the knurls on the stock? The way I use the scissor type tool is to set the tool so the wheels just drag the stock at the top and bottom then move the carriage off the work then apply some "cut", start the lathe and bring the wheels back onto the work (a good chamfer on the stock helps here). I have always had good success this way

I made the basic one from Hemingway and find it very good, was also an enjoyable build. I modified the size of the arms and pins to accommodate the more commonly available 3/8" wide wheels. I have used the tool on both a Boxford and a large Colchester at work with great success on both

Thread: Surface finish for aluminium sheet?

20201226_093408.jpg

I made this money box for my son and basically used the exact same technique described by Jim above. A wooden dowel with a piece of leather glued to the end and used a mix of oil and surface grinder swarf as the abrasive. Cover the surface in oil and then sprinkle a small covering of the abrasive and then just work your way across. It's best to set up a fence to keep the pattern square and I just did my overlaps by eye. Obviously a spacer is then used between the part and the fence for the next row and so on and so on.

Thread: Naerok 350 mill
09/05/2021 09:28:27

The reason for asking is that mine came fitted with an A32 and an A23 but these appeared too tight to select all speeds. On seeing this thread I ordered an A25 (the A25 size can also be confirmed from a picture on lathes.co.uk) but that seems too loose. Mine has had a replacement motor fitted so that may be cocking up the centres for the smaller belt so maybe I will try an A24

08/05/2021 22:35:37

Sorry to drag this thread back up but no sense in starting a new one. Would someone be able to confirm the belt sizes for the Naerok RDM350?

Many thanks, Craig

Thread: Think you have trouble losing your chuck key?

Impressive work. Inventive use of the pantograph too, I like it!

01/04/2021 14:24:50

Very nice indeed, would also be interested in the finer details. I like how the jaws are to scale also because that is my problem with the ones made for the kits like David's, they are always too big (no disrespect David, your model looks great) but the makers (Stuart and others) must deem it too fiddly to do the jaws to scale?

Thread: Er32 3mt Collet Holder

I wondered the same when I first got mine but it is there to retain the collect, the collet snaps into this offset ring and it holds it there.

Good pictures and description here: https://www.arceurotrade.co.uk/Catalogue/Collets/ER-Collets/ER32-Collets

Top work on the finishing there you really have aged it nicely. If you would have said it was an original engine I wouldn't even bat an eyelid

Thread: Making mild steel look like cast iron
22/02/2021 10:09:54

Thanks all for the tips. I do know someone who does some agricultural sandblasting which might work to blend everything in and give it a bit of texture but that would obviously leave it a light grey.

I had thought of going down the route of submerging them in brine to let them go rusty in order to give them a bit of texture and then treat them to remove the rust. I do believe I have used a rust treatment before that turned the steel black as Neil described.

I do have a needle descaler which i might try out also for some texture.

Finally I could try polishing them with Zebrite and see how that comes out.

Thanks all for the ideas

Craig
