Yeah definitely expensive for what it is!

Good idea though

I made such a thing donkeys years ago when they were a £5 in Exchange & Mart .
These days I'd buy an Aldi /Lidl style sig bottle ca £7 , carefully drill the shoulder and fit a modern bicycle innertube valve with sealing washer over the tube . Done by slipping three of soft wire in through the hole , making a small kink or knot if it is electrical wire make it into a full loop after getting it to poke out the stopper hole then slip the valve tube over the wire up side down and invert & jiggle the can till you can pull the valve tube through the hole. fit another sealing washer and a thick soft flat washer then put the retaining ring on and refit the valve on Use the aerosol spray & lift tube off a normal spray can & araldite it from the inside of the stopper so it is proud enough to fully depress the spray buttin ( from which you hav turned th top down to give a flat surface … don't take too much off. or you'll need to turn up a new brass plug ( and knurl it ? ) . There's loads of ways of mounting the spray head still in some of the aerosols metal body externally to the turned off stopper using a shouldered brass
With practice you can actually remove the complete plastic spray unit from a rattle spray can & insert it in a shouldered screw capped tube so it is as an insert set in the bottles stopper .

One way I've seen a homemade filler / stopper air charging point was with valve stem as a square block of brass with the air charging valve set in the side of the block via a sealed thread . One guy used /modified a large tall Brasso can for his easing oil sprayer as the screw top lid was easy to work with .


The original refillable sprayer I made was a normal tall spray can , that I fitted up with one of the older cycle inner tube 5 mm valve stem tubes fitted with a Schrader valve core that had a round base on it rather the modern ones that are fused in to the rubber . I sweated soldered it to the shoulder of the steel spray can . It was filled by taking out the valve core , then filling it using a large vets syringe and very large needle on the syringe . Reinsert the valve core and pump up with my racing bike's tyre pump .

These days the fused in valve units are easy to sort ….. Take out the valve core and then slip the tube in a small lidded jar of Nitro Mors paint remover .. it will dissolve the rubber off the stem tube in a few days , wash it clean with boiling soapy water in a washed out bean can etc. then re rinse it in clean hot water to ensure you have removed all traces of the Nitro Mors . Check it is clean on the valve seat using a cotton bud or three , then wire wool it shiny . Don't try to use a blow lamp etc to burn the rubber off or you'll spend hours & hrs trying to remove the crud and clean the valve seat . Turn up a mount sleeve & shoulder in brass and solder /sweat them to the shoulder of the can , making up a shaped brass fit on the shoulder plate if required .

Or get a lorry inner tube or a brass tyre valve brass swan neck tyre extension tube and thread or sweat that in a mount .

Test it by3 /4 filling it with water and pumping it up three or four pumps then slip it in some cool clean water that you've added a few dish drops to , to check for leaks /integrity.

The tumble reverse and change gears I need a 20t for my reverse if you have a spare as where I'm buying my other gears only have them with a 12mm bore and I'd rather not have to bore it out

One thing I'm looking at when I'm a bit more au fait with my 3D printer & the Fusion 360 drawing programme is 3D printing a full set of sacrificial gears in black ABS or some sort of tough nylon for my 75 yr old Atlas lathe. As some of the high pressure injection moulded duralumin gears are a bit crazed & replacements are hard to obtain at sensible prices this side of the world .

It seems some of the guys on the Hobby - Machinist site in the USA that I play on are already using their own homemade ABS gear wheels on their machinery , using Fusion 360 as the design & printing tool , it has a plug in programme to make parametric gears that you can buy for a couple of pounds ( $'s). These allow you to make all manner of gears in 3D plastic or cut using CAM . They seem to come highly recommended too , for the actual teeth don't take a lot of strain if you use the lathes with a bit of sympathy . Even if you do get a failure once every blue moon it would merely be six or seven hours to set the printer up and print a new gear of two .

where from?

I could do with one for my electrically powered wet stone grinder

I forgot Machine shop.

Then it just got worse

Closer examination reveals it to be bits of clutch pack. Probably sitting laid up for a decade didn't do it any good, and it's had a slight tendency to slip recently under max torque.

I'm not too shure on why you need to hit the end of them yet what benefit will it have getting a screw out

Often giving a tight screw a sharp tap with a small hammer in the first place , using the correct sized steel headed screwdriver held accurately & vertically in the slot to transfer the shock down the threads frequently helps loosen them enough to simply unscrew the tight screw . Instead of chavelling the shoulders of the screw slot off/ out by forcing the screw driver round without giving the screw the helpful shock treatment . It can also help when removing a rusty thread screw through a thick plate . Back off every half turn give it a light tap then undo a bit more , give it another light tap .repeat ......use easing oil and a wire brush to clean the threads if able to . etc etc .

Sometimes it worth putting a red hot steel rod the same diameter of the screw head on the screw end for 5 to 10 seconds if you know or suspect a form of stud lock has been used as the heat transferred can help soften the stud lock enough to start unscrewing .

The hexagonal head on the screwdrivers is also used for putting a socket & Tee bar on the screw diver if there is space enough to get an even vertically applied tourque down on the screw . Using a ring spanner on the hex head like a lot of guys do , can sometimes result in the screw driver blade going out of vertical and wrecking the screw head slots or occasionally splitting one side of the head off the screw for you can put a lot of pressure on a long spanner without really realising it .

That's why I bought them for the ability to put a spanner on as I don't have many you can do that on I've got my impact driver for stuck screws

You've started the workshop equivalent of digging a hole, the earth never all goes back.

If the earth won't all go back we just dig a hole and bury the dirt.

Just like unpacking something new from a box, then trying to pack it back in.

Have acquired a gas valve tig torch for my favourite price of free. Just need to get hold of a box of bits and some argon then I can have a go at some lift arc tig.

Have a look on Thingiverse for parametric spur gears, they need (free) OpenSCAD to generate your choice of tooth-count, DP/Module etc. And there are even parametric bevel and helical gears...
Me, I use TurboCAD Pro for gear generation, cos I can

Got these today

Unfortunately just for the night while thefolks are off galavanting. A walk with dogs is very pleasant though.

A walk with dogs is very pleasant though.

A few years back, I used to house & dog sit for friends, usually for 2-3 weeks, - one lovely lab [sadly no longer with them] and a bonkers spaniel [although they all are].

Just don't tell the better half I said it! She's been after a dog for ages, but with my shifts and her working it would be alone for big stretches of the day, and the house isn't really big enough for a dog plus the 2 cats and us. A walk is definietly better with a dog or two.

We live on a narrow boat and had two GSD's and two cats, and two us, space what is that!

You're going to need to delete that in-case she sees it!!!

A flat empty space. (Well, fairly flat anyway..) Which I cant use yet. The mixer seized and I had to mix half of it by hand, and some of it was a bit wet, and the dog destroyed the sitting room while I was doing it, but apart from that, it was a grand day..
