Stuff you have made today

[Dr.Al]

Haven't been on the 'puter for a few days, but over the past couple of days I made this:

It's a rotary broach (when I took the photo I hadn't sharpened the 3 mm, 5 mm or 6 mm hex bit; the 4 mm hex bit is fitted into the holder in the photo).

Close-up of the test hole - it looks like the sides are curved; they're not: it's just because I went a bit overboard on the chamfer before broaching:

Today I made another hole. Only one.

Note the size of tree root -I only cut into a small corner of it, and once through that, a few more below. There was some swearing. After that just clay, the engine drill went through quick.

The big post is in. 5 small ones left

[Kram]

Yeah toooo much water I thought it would need another bag as it a a bigger hole, but I put smashed bricks in, and it didnt.

<sigh> I will get mine finished this week, could have used it recently too. It has been in the "Under Construction" pile for about 18 months

Anyway, today I made a small branding iron for a farmer friend, his sheep are being stolen again!

Made a start at a new door for the shed as the old one is timber and starting to get weaker

As i had it there I cleaned up a bit of rust from a sheet of 2mm and start slicing it with the plasma (lidl one and it’s so much handier than a grinder) hopefully have it all welded up and sprayed tomorrow. Only went out to see what I had to do it didn mean to actually do anything today

Somewhat less technical than @Hood 's work above but kept seeing this image today.

Just wondering if you know the artist and got permission to use their image?

How did you incorporate the degree or so offset to get the broach to wobble, that it only cuts on one point at a time?

Urmm... I cheated: I just followed the instructions. It's made from a kit: in the past I've generally avoided Hemingway Kits as they're stuck in the dark ages of imperial units, but I decided to order two of their cheaper kits and see what they're like and how hard they are to convert to metric. The rotary broach kit was already in metric surprisingly so I just got on with it and it took about 3 short mornings to make it from start to finish (including the broaches). I could have made it quicker, but it got too hot in the garage and so I gave up by the time it got to lunchtime! The other kit I ordered I'm going to model in 3D CAD and convert to metric before I start manufacture.

In more direct answer to your question (the above was really just so I can't claim credit for the method):

The housing is made in two parts (well, three if you include a screwed-in retainer piece). The shaft itself is simple - a long narrow diameter and a short wider diameter with a slot cut into it. The other bit of the housing (which holds two roller bearings and a thrust bearing for the spindle) is made as a simple holder and then one face is machined at 1° and a notch is left in it to slide in the groove of the shaft. The two screw together in such a way that they slide relative to each other along the groove. You then fit a cutter, mount it in the lathe tailstock and align the two parts such that the tip of the cutter goes into a countersunk hole and is hence on centre. Tighten the screws holding the two parts together and finally mount the whole thing in the chuck and skim the OD so it looks like one piece.

Quite neat really and very easy to do.

Made a smile appear today as I found a newt in the pond while gardening.

I spotted one the newts that live in our whilst replacing some of the tiles that form the surround to the pond. We don't often see them in the day, the best way of seeing ours is to go lamping on a warm evening.

As well she might be

That's just a bit creepy, imo.
