I have one of these machines and love it. The mill head needed stabilising as it used to drift around it's pivot but fitting a locating plate and locking bar resolved that problem without compromising access. I've also made a revolving stop bar for easy repeatability on small batch work. This meant reversing the position of the feed lever which was easy to get used to.

Other mods include a reversing gear for left hand threads for repairing one of the four jaw chuck jaw screws after accidentally over tightening it. And re making some drive gears after my son managed to smash the toolpost into the chuck when pratting around with it when I was away on holiday. I've also made some larger drive gears for an extremely fine feed for a job I needed to do.

I use it mainly for hobby work now but also for repairs to equipment for the school I work in. Take care of it and it runs well with a more than reasonable accuracy and repeatability.

Great machine for limited space and comparatively low cost.

As an apprentice many years ago. I heard of someone who had a pin hole in a glove and after working with a vat of hydrofluoric had not used a proper hook so consequently got the stuff all over the glove. When they took it off away came all the skin as well. They subsequently lost the hand. really not nice stuff.

Thanks Neil.

Anyone else spotted the deliberate mistake in the competition rules?

It would seem that the closing date is 2015 not 17. Oh dear! Actually it corrects on the entry confirmation.

Doh! what a simple idea, Love it. I am going to severely nick that one. Thank you.

I've just looked at my pocket mags subscription and only have this years mags available but have been a subscriber for several years. I've blown out windows 10 and gone to Ubuntu mate now 17.04 (Linux based) which is much more stable secure and does not take over an hour to update on startup which was my biggest problem with windows 10. if I want to access the back volumes on line do I still have to have a digital subscription, mine is due in October but I don't think I want to renew it because I simply don't use it enough.

HA!!

Pleased to read it happened to someone else. The same was done to me as an apprentice at Rolls Royce. Mine was a plastic mug and I didn't pull the handle off. It was revenge for a whole range of pranks pulled over several weeks. Served me right really.

Didn't Robin Hood wear hose?

That looks fab Neil. I look forward to receiving it.

Thank you Micheal.

In which case there should definately not be any asbestos. Dismantle away.

I would use a 30 amp strip in order to protect the wiring. A Domestic power ring is usually protected by a 30 amp breaker so your wiring needs to be at least this rating in order not to melt before it can trip. Yes there should be a smaller fuse in the plug but you would be amazed at what some people try to get away with.

If it is an old cooker and contains asbestos or you think it contains asbestos, DO NOT DISMANTLE IT, Asbestos kills very slowly and ultimately painfully. Even white asbestos. Dispose of it at your local authority tip, informing them you think it contains asbestos. There are very strict rules and laws about asbestos handling now and very heavy fines for not following them. You as the owner can be held accountable. Look at the regulations. Sorry to be a kill joy. If it was made after the 1980s then there should be no asbestos in it as it was outlawed.

It's the gear mechanism which lowers the Mirror head on a short throw projector. Unfortunately it's not possible to bypass the assembly as the projector won't stay on without the gearbox working.

i am now wondering if one made with aluminium might not be better. I can do that myself. Any thoughts folks?

Hi Guys the whole gearbox is plastic. It got damaged when hit by a ball that shouldn't have been thrown. They are a common failure component looking on Ebay other sites available. as most of the same projectors have a failed gearbox. The diameter of the large gear is about 34mm by 3mm high. The smaller gear is 6mm high.

Hi

Can anyone in Leicesteshire help with a printing request please?

I am a premises officer in a primary school in Hinckley and need to repair a broken gear in a projector. I've drawn it up in FreeCad and exported it to an STL mesh. It is a compound gear with 67 and 9 teeth although the 9 tooth gear may be incorrect. I had to work it out from the remnants of the smashed gear. It may be 8.

If anyone can help we would be extremely grateful. We would of course pay for materials used.

I've attached a photo and can give dimensions if anyone can help.

Be careful what you use on the dash. I had a cardboard air freshener sat on it. which dissolved the top layer of the plastic. it was freebee from a car wash. Oops.

I've just done my house with celotex board. Very cost effective and easy to use. It's foil backed so add tape over the joins and you have a vapor barrier. it comes in various thicknesses. I used 25mm on my stairs and 50mm over the rest of the house. Space loss is minimal and because you can do it in small affordable stages you don't fall foul of building regs either. I did check with the local authority on that one.

I'm considering doing the same in my shed.

You may indeed MichchaelG. I hadn't connected you had already suggested it.

Take dimensions off the damage area for reference.

Machine it off and bore through the pully to the outer diameter of the spigot.

Turn a new spigot to the external diameter 0r the cast shoulder to register against the shoulder.

Turn one end down to be an interference fit in fit in the pully and press in, you might also want to use a bit of locktight. You could drill a pin hole the other side on the diameter line and drop in a pin to stop it spinning under load.

Remount in the chuck and set running true and drill and bore to the correct internal diameter. Then face to length. Don't forget to re-drill the lubrication hole if that is what they are.

Turn the o/d to allow for clearance on the springs.

Hold it in a drill if not too long. Then file and emery cloth.
