For less than £100 delivered you can get this - just bore the pulley and file the keyway and its done **LINK**

that would make life simple...if only I ever dared to fit my 4th axis. Why not go the whole way and cut to size with a flat tool? Surely a good finish is possible? My cnc computer got filled with dust and went pop earlier in the week so had to drill 300 holes by hand, awful job! Time to build a decent enclosure for the pc and driver box so it doesnt happen again. Theyre great when they work!

The psu on my cnc computer expired yesterday, got to have serial port and xp to run my version of Mach3. £20 including postage for replacement pc off ebay....thats why some of us still need old computers.

shop warranty 12 months, they last me about 18 months so should be worthwhile.

Ady1....all different policy numbers...here are a few more...

MichaelG - it is covered for any breakdown for three years from purchase date. I have never had one last two years (and never had extended warranty) so for £11 extra im sure I will get my monies worth. Ive now got 78 warranty policies.

very nice - any idea how much the PS item is - must be over priced if its been there so long?

Im currently getting a new one every three minutes. I rang them - they said someone musy have pressed a wrong button. Well if thats the case theyve been up all night and are still pressing it

And so it continues.......

Now at 28 and counting. Me thinks there is a tiny fault somewhere in their software!

I bought a new Dremel yesterday and opted for the extended warranty - so far they have sent me 18 extended warranty policies, each one a different number. I hope they arent billing me for these! If any of you work for Argos...what?????

one solution i have used when milling thin brass is to soft solder it to a bigger piece which wont deform in the vice. Solder paste is good for this job but not essential. When its milled simply hot the piece up and off it pops. Soft solder can be wiped off ur lightly sanded.

Indeed Steviegtr, eventually this technonogy will filter down to home use. Not sure how strong the glue will be in 100 years though

Its been on and off since 1998, different series and different channels so its on hold...it will be back.

Totally agree with Dave W, unless you are gas cutting big chunks of metal or gas welding you dont want to be wasting a lot of money on acetylene, and you certainly dont want it near houses. If its in a fire and doesnt explode your neighbours will be forcefully evacuated for 48 hours (in UK), your home insurance is void and you wont be popular with the local fire brigade, police, neighbours and so on. Remember the M25 being closed in both directions for two days a few years ago? That was an acet bottle in a fire in a scrapyard near the motorway! Oxy prop is relatively safe and cost effective. You can buy new rerulators very cheaply - dont be tempted to buy second hand, too many out there never serviced and faulty. I bought mt torch and arresters second hand. Go for the small brass BOC type if you can, they are a lot lighter than most, and being vintage are well made of brass. This torch uses the smaller fittings (size eludes me - 1/4 bsp as opposed to 3/8 bsp? ). Make sure you get 6mm bore hose, it will supply all the gas you need and is a LOT lighter than the 3/8 bore. Trust me, silver soldering with the bigger hose is not fun. The nozzles which came with these torches were originally for welding and most of them are too small for my silver soldering needs...so I drilled them out a lot bigger. Using oxy/prop is a complete game changer. No faffing about with thermal blocks to keep the heat in - you obviously still need a hearth of some description. For my range of stationary and marine boilers mine consists of a single foot square of bbq lining board. No amount of heat will upset it and I simply move it to one side when im not using it. Always use T5 flux as its not worth risking the flux burning out before the job is complete. No silver soldering today, instead ive been annealing copper plate and pressing end plates. A big nozzle on the oxy/prop makes reasonably short work of it, even when youve got 60 to do. Hope this helps in some way.

Pendle Steam Boilers

Thanks for the link JB...never heard of them, but they make some nice, if expensive complete engines. Going to take a few cancelled shopping trips to get this...**LINK**

If you think £20 will take the wife shopping for 90 minutes im not suprised you havnt got a wife (only joking)....give her £150 and you might be in with a chance.

I once had one of this type, they will tack stuff together but they will not produce a structurally sound weld. Thats not to say that in the right hands (I was a full time coded welder back then - I could weld) a strong weld is impossible, but where a complete novice would struggle with a proper mig set up they would surely fail with one of these. On the cheaper models the wire permenantly live which only adds to make things more difficult. The weld will invariably look like bird poo! I could get a half decent weld on thin steel by using max amps but other than that it would just spit bits of metal at the job which might or might not fuse together. I gave mine to my brother inlaw who most certainly confirmed the above!

Ive never met anyone using a generator for brazing, not saying there aent any, but I have seen them used on youtube. With an average flow rate of about 2 litres per minute (five max) at ambient pressureyou would not be able to burn with a decent flame for anything but the smallest of jobs. Fine for very small work but dont even think about using it on a boiler anything bigger than a mamod. Given that you can easily get the same and a lot more heat out of a b&q £20 prop torch the cost would be very prohibitive...But, for super fine/fiddly jobs you would have a lot more heat control and accuracy so it does have a place in some workshops.

Ive got one burried in a shed somewhere....never liked the round bed though. Welcome Neil,

I took one off a few years ago, cant recall the detail but I remember it was far from as straight forward as I had expected, sorry not much help but be prepared if nothing else!
