Finished my Barrel Vice, well, it makes sense – If you make posh guns you need a posh vice, no?

Nice job Graham. It will serve you well. A few years ago I loaned my barrel vice and Mauser wrench to an ex-friend. I never did get them back. I vividly recall my first barrel job I removed the barrel from a Parker Hale 1200 to build a target rifle using a PH 1200T barrel. No barrel vice back then although I had built a Mauser wrench. I removed the barrel using 1/2" nylon rope and a pick handle. When the barrel finally let go, it did so with a resounding snap and fully unscrewed from the receiver.

Just finished assembling my Walther 1950's KKM after bedding.

In the interest f Full Disclosure, Bogs macined the surfaces for me on his big Mill while I tried to break his lathe.

It kept blunting the flycutter so he got cross and thrrew a Carbide cutter at it. Pretty tough it was too.

Visited B & Q yesterday to take advantage of my Senior discount card and noticed that they were selling off 600mm sanding belts coarse grade, also some sets of spanners Stubby style.

Bought 2 bags of compost that I could barely lift into the car. Then very busy at work catching up after 2 days off.

took a shallow box of combs down to the bees and put them on a hive and also killed a Queen Wasp that was hanging about outside the house. One less nest to deal with!

Anyone bought one of those fractional calipers? Always wondered about them and just fancy getting one……

graham.

Graham

I bought some digital calipers with the fractions display. I'm not sure what prompted me but I never use them in fractions mode.

I think they may be aimed at woodworkers in the USA, I went through an assorted box of Allen keys thinking I would be able to quickly separate the imperial from the metric. In practice it was best to check them all in metric mode and its then obviously which are which.

Same really with drills, if the shank markings are hard to read or not present because the drill is tiny I measure in metric too. There is not much point in measuring, say a No 73, drill if the best resolution is 1/64".

I have just remembered why I bought them. They were promoted at having a large character display, however that is only true for digits before the decimal point which rather defeats the object!

In metric mode the display looks like 'O.oo' and in imperial even sillier as 'O.OOoo' so a bit dogs breakfast like.

Also going on Saturday

Bugger, Especially Bugger about the font size, one of the big attractions for me. I will have a look about tomorrow and see if something seduces me.

My thoughts;

Ultrasonic vibration stress relieving will do the trick. Finding some one who can relieve such small parts maybe a problem however. There again it can leave the material buckled (having taken out the stress) and so if it is then straightened stress will enter the job once more.

May I make a plea to users of this forum to include a few words of text to indicate what their reply refers too.

This is my attempt to remove as much stress and strain as possible from life!

On reflection, starting a thread with 'What did you do today (2015)' is the root cause. Maybe there should be a new (dated) thread 365 times per annum.

Over the last couple of days I have been fitting tapered gibs to the mini lathe. I made the gibs from brass and have had some problems with distortion due to, I think, internal stress. I'd be interested to hear if anyone has any thoughts on this and if this is the case, to know how to stress relive brass. The lathe is back together and although the gibs are not perfect ( I'm going to remake them), the results so far are much better than before.

Regards.

David

I'm not sure there is a way of stress relieving brass. When using extruded brass bar to make parts I have learned to remove surface metal from the opposite longitudinal surfaces to prevent the banana effect. Its a great business model for the non ferrous metal industry.

[Gordon WParticipant @gordonw]

Does it really matter if brass gibs are a bit bent? Surely by the time they are fitted they will be straight ? I ask because on my cheapo lathe the steel gib strips are bent and were rough, I polished them up a bit with a file and just put them back. They are much better but still bent if removed.

[Clive HartlandParticipant @clivehartland94829]

Anneal the brass as is and all will be fine, machining extruded brass sections will always cause bending.

Clive

[Neil WyattModerator @neilwyatt]

I made one from non-compo brass I bought by mistake and found impossible to make a good gear from. It had a mirror finish which I flatted down with 1000 grit wet and dry, it made an excellent gib strip and being the right thickness I only had to chafer the edges.

Neil

[John HaineParticipant @johnhaine32865]

David, do you mean a tapered gib? Fitting one of those would involve machining out the dovetail to a matching taper. Both the mills I have had with with tapered gibs (an Aciera F1 mad the Novamill I have now the gibs are steel I think because they have to take quite a high longitudinal compression force without buckling.

[john carruthersParticipant @johncarruthers46255]

Had to try it hooked up to the coffee machine;
Esspresso anyone ?

[Johnboy25Participant @johnboy25]

That must be the best alternative use for an espresso coffee machine I've ever seen! Not that I know anybody who's actually used it for anything else! 😳

As a steam generator – what pressure do you get out of it just for the record!

John

[john carruthersParticipant @johncarruthers46255]

I haven't measured it, have to get a guage rigged up. Looking online they seem to range from 8 to 15 bar? Handy little tap on top. You have to blow the standing water out first. The wobbler makes a lot of condensate until it warms up. The advantage is a quick head of steam.

 

Update; I had to go and have a look. The plate on the bottom of the DeLonghi machine says 15 Bar. Bit of luck, it was going to be thrown out so I grabbed it. It only needed the filters cleaned
Now to make a Wallace and Grommit coffee stirrer

After letting the Gade's paint harden off for a few days I put it back together last night and today, seems a coat of paint has done it no harm. Next to get it fixed to the cart and wire it up with decent looking cotton braided cables.

Visited Harrogate to "save a fortune" – well that's what women say in shoe shops isn't it????

The youthful Mr Stevenson kindly sharpened up some cutters for me ( he was doing a roaring trade!) . John"Doubleboost" was there so got to meet another good guy.

Tomorrows payback time- taking father in law ! Must be worth some points from SWMBO.

Couple of impressive electric gliders ( might have to get mine out of loft and dust down now summers coming)

No signs of our enlightened editor (Neil) ? Ketan put in a guest appearance.

A good day but could have done with some more seating area inside!

[Jesse Hancock 1Participant @jessehancock1]

Ian…

The post on stress relieving was aimed at the guy having trouble machining his gibs.

I would have thought that Ultra Sonic Stress Relieving was self explanatory. And of course by the time I posted it got lost in the tide of other posts.

Very nice engine, Jason. Beautiful detail and sounds very smooth.

Is it 1/2 scale or 1/3 scale? Description says both.

Murray

[Neil WyattModerator @neilwyatt]

I was at Harrogate from 12:00 to the end of the day. would have been there earlier without three sets of roadworks and two misinterpretations of the GPS!

Coming back was even worse as I had to divert via Leek to pick up a 'vibrating plate machine' that turned out to be a 3-man lift. Now if I can get a similarly excellent ebay bargain on a bridgeport I'll get my wife to fetch it

Sorry about that, it should real 1/2 scale on both. My excuse is I just before doing the video I had been looking a the purchase of the next hit & miss which is at 1/3rd scale, bit smaller than I usually make with 6" flywheels but it mostly drove a specific item which I hope to scratch build for it and that will take the finished model to over 24" tall.

[Steven GreenhoughParticipant @stevengreenhough56335]

whilst at Harrogate on Friday I bought a little vertical slide (amongst a few other bits n bobs). I fitted it this morning.

I removed the compound slide and dismantled the cross slide from the carriage, after making a centre line where I wanted it to sit on the slide, position to give equal and full travel of the cross slide. I then popped, drilled and tapped two M5 holes, carefully nibbling at the iron with my cheapo drill press and a small centre drill initially (I have no spot drills) then up to 4.2mm before tapping by hand (roughly in centre of pic)

When fitted, I get full, equal travel either side of centre, about 65-70mm I think, and just shy of 50mm of vertical travel (this is restricted slightly as the bottom of the vertical slide grounds out on the carriage approximately 4-5mm before the slide has reached full travel:

A simple job but a significant one for me as it's the first modification to the lathe that I've undertaken.
