What sort of cost is prohibitive?

i have a lorry with crane sometimes available in those areas

it certainly looks well made

its like a small welder 30cm x 20 x 20cm and weighs 5 kg empty

i’ve only done edge polishing but the flame looks good enough for precision heating of small parts/jewellery etc

it runs for about 20 seconds and then switches off on a pressure switch then cycles on/off as you use the produced gas

Well i filled it with my mix of 150g naoh and 1 litre of water and filled the booster with methanol as directions and it certainly works well.

as said teh flame is very hot and virtually invisible though it polished some 15mm Perspex edges very well..

How long should i leave the electrolyte in? And if it should be removed can i save it and reuse?

It was only £110 delivered from Belgium by ups

Has anyone got one of these hydrogen generators i bought it for acrylic edge smoothing but seems it can be used for small repairs on jewellery etc

it came with some naoh 500grms.the instructions say make up a 15% solution..so that’s 150gr of naoh to 1 litre of water?

anyhow does anyone use one and have any operating tips?

What’s the part between the 2 biscuit tins that looks like it clamps on the bed and has 2 arms with what looks like a offset centre ?

whilst i cant speak for flash ultra i can recoomend" elbow grease" which is sold in the cheaper outlets at only a £1 for a spray bottle.

i buy it in dozens when i need it spray it on brush and wipe

it also works well around the house too

Here is one I made for a Colchester student out of a mini steering rack

I had a call the other day re stopping unwanted calls.

the Indian sounding woman was most insistent that I was responsible for the landline bill and I was a homeowner and younger than 85.

i responded with well I’m 87

call ended immediately

whats the method in only targeting under 85 year Olds?

Remember that the current draw for this motor is only 33mA so even a fuse will struggle to protect that

I’d agree that some way of detecting a stoppage would be best

They made a mistake on the listing for the sets and cancelled the listing relisted now with proper price for the sets

I saw a video on YouTube about someone with the same problem

He discharged them (if not already) then put them in the freezer for 24 hours then let them defrost well then recharge in the normal way

Then all was good (apparently)

Is there anyone near Loughton who could pick up an eBay purchase and post it on to me?

Ian

Bisley *. multidrawer filing cabinets 15 drawer ones I use

looks like a leather cutter you place the shoe on the work press with your palm on the knob and the blade comes down and just goes under the material and cuts as you glide the tool along your cutting line..

does that seem plausible as i’ve Not seen the blade

If you just want a piece of English or European oak the size that you quoted let me have your address and i’ll Drop a piece in the post for you

i can do it rough cut ,planed, or planed sanded and finished

As i said earlier

if you take the end cover off and defeat the safety microswitch if there is one

run the machine and use the half nut lever to engage and as you say stop the lead screw and drive shaft.

it will be obvious where the problem lies

if the whole gear chain stops the problem is at the headstock

if it stops but the shaft that the first gear runs off still spins its a shear pin there ( like earlier cols)

if the gears run but the input shaft to the gearbox stops its a shear pin there

if everthing runs its a problem within the QCGB

Just take the end cover off and use the lathe ....trying to stop the lead screw turning as you described ....you should see where its broken

well on my Colchester lathe (earlier than yours) its on the first gear drive next to the spindle

Sounds like your safety pin has broken

Yes to all

slight proviso ...I've found that abs needs to have a warm environment as well as heated bed so build an enclosure round it
