………….. and blow hot air at it

But if I do that I'll never see the components again. That's the trouble with surface mount components these days, one sneeze and you have to re-order, as you'll never find them. On the PCB I'll be using 0402 resistors, been a while since I last used them. They're about as small as I'd want to go for hand soldering, but fortunately the boards will be auto assembled with a pick 'n' place machine.

PS: That's why I'm building a big engine, it's the perfect antidote to all these darn tiddly widdly components.

If you have a proper rework gun it will have a power setting so you DON'T blow them away. I've used mine on 0402 resistors!

A rework gun, the holy grail of metal cutting.We have many tools that take away material, but next to nothing that can "put on". I suppose weld build up might be the closest thing.

I've got a dual soldering iron station which fine for removing simple components. I don't need a rework gun, my PCBs mostly work first time.

If a board does have an issue it goes back to our assembly company for rework. The last three returns were for components the wrong way round, presumably a foul up in the tape 'n' reel.

Never used them myself but 0201 resistors are 0.3mm x 0.6mm and are pretty much invisible to ageing eyes. But at that size, they are almost an inhalation risk!

You should be so lucky.

Bought my first lathe home! Proud owner of a myford ML7, can't wait to start working with it, although it needs rewiring and a new belt by the looks of it.

It's mostly not luck, but a combination of experience, ability, attention to detail and a robust review process that eliminates dumb errors like wrong PCB footprints and incorrect schematic symbols.

Of course what'll happen now is that my next PCB design will turn out to be a complete lemon.

I've always been amazed how our dogs can sniff nettles without (apparently) getting their noses stung.

Today Rosie stuck her nose into a nettle patch and leapt back with a great yelp, then was rubbing her head on the ground and scratching with her paw!

When I got her home I noticed her eye was closed and bloodshot -she must have managed to sting it.

She was very good and let me put the last of a bottle of optrex on it and it seemed to give her relief, but she's slept it off and apart from blinking more often than usual it's looking more or less normal now.

Well sometimes you have to do something different ……

I hope you're going take it al apart give it 3 coats of paint and then re-assemble it before you give it to the child!

Then it needs rear sets (and an engine).

Been reluctantly sorting my workshop and decided to sell the tools etc. I don't use much.

Most model engineers seem to be hoarders like me and God willing will finish with my workshop completely in about 5 years time.

Asking relatives who have no idea of our hobby to dispose of your workshop equipment is a minefield for them.

Would be nice if some genuine enthusiast with little finance could receive some of the tools eventually.

To help a budding enthusiast whatever discipline is better than thinking how much you can get for your workshop.

Being in that position when I started my hobbies plus motorcycle sports I was grateful for friends and people I did not know helping me.

[Andy HoldawayParticipant @andyholdaway]

Windy, that's a wonderful gesture, and I'm sure the recipient(s) will make good use of whatever you pass their way. A great step on the ladder for a young or beginning model engineer.

This is the spirit that I see quite often in our hobby. Well done!

What tools are you getting rid of, I'm new to model engineering and building a race bike. Happy to purchase anything I may need off of you

[WindyParticipant @windy30762]

Hi Curtis,

Tools that would be possibly of use to a budding race biker wont be available for around 5 years when I finish with the workshop.

What are you building race bike wise I'm very involved with the top speed lads and lasses as Elvington that is not far from me and know the surface well as slid along it at estimated 150mph in 1975.

A bit slow compared to Beccy (fast granny) when her mishap happened.

Don't forget to put safety guards around those rockers to stop little feet and fingers getting caught underneath.

[Neil WyattModerator @neilwyatt]

Cleaned up the tank motors, had to take one apart and improve the solder tag/brush contact. Put the gearbox in the ultrasonic tank, then spray of 3 in 1 (maybe not ideal but 3 in 1 is what I put on it about 37 years ago). Ran each motor for a minute or so at various speeds and now it runs as sweet as a nut. looking forward to this.

Putting off progress with Jovilabe – etching a 10" square sheet of brass then turning it into a huge gear is a bit intimidating… only one chance to get it right!

I hope you had your bike clips on Paul!

[John Stevenson 1Participant @johnstevenson1]

Windy, good on yer.

I'm a bit like you I have about two years to dispose of a working jobbing shop AKA Bodgers Lodge as its situated in premises my daughter will shortly own.

However I am going to build a new workshop at the new house next year when the weather breaks, not big, I reckon 20' x 12' or 14' is as big as I can get in, possibly down to 18' x 12'

Sound quite big by a lot of peoples but it will need to house two of us as the Delectable Debs ® ™ has a KX3 CNC mill, a CNC lathe and a Colchester Bantam and I have a 14 x 36 lathe, SX4 mill and 900 x 600 router plus all the attendant hand tools. In fact I worry that it won't be big enough.

Big TOS lathe, Blidgeport, Gear hobber, big CNC mill, all the welding equipment, MiG and Tig, power saw, etc will all have to go.

TBH I'm looking forward to it so then I can do what I want and not what customers want.

Should give me more time then to take Ketan thru the small claims court to get my £4 back ?
