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 .

@Parm

where from?

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

I forgot Machine shop.

A customer called in to work before going to the tip
A double set of old metal draws

Then i started to move things around

Then it just got worse

The opportunity to avoid disaster, just in the nick of time.

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!!!

 

[Chillitt]

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..

I'll give it a blast in the next few days
