I made a spit for a Citroen 2CV van body - used for welding and spraying. I just used a scaffold pole and clamps and a couple of "A" frames.

My loco frame was a couple of 3/8" ply triangles with a couple of bolts locating in the buffers and a third 6mm bolt for the axis. The only problem with that was access to the smokebox.

Years ago, I had a woodworking bandsaw made by a pattern maker. Apart from the plumber blocks and shafts, it was nearly all made from plywood - even the 4 wheels that it could be moved about on. It was excellent, would cut straight etc etc. depth of cut about 7" and 18" throat. Unfortunately it was too big when I moved house!

Factory re-furbished units drop the price from that of a new one. You usually get a new battery, screen and charger.

Bill, Not done it yet is being a little precise and could be more helpful if he had explained the difference. I believe that a DTI is a finger gauge which Generally has a smaller movement that a Dial Gauge. That said, all the DTIs that I have seen are graduated and equally acceptable for measuring distance within their range.

For John's application, I would consider a DTI or Dial Gauge to be quite acceptable.

Silver solder that size you can do on the gas stove, small kits on auction site will give you plenty for about £9, probably cheaper than buying hex bar. Make sure you get a kit for stainless steel, which can also be used on steel, brass, copper

I hope you don't mean 20 - 40 thousandths of an inch !! a thousandth is 0.001". (a hair diameter is approx 0.003" to 0.007".

Did you mean 0.0002" - 0.0004" ? ie: 2 - 4 ten thousandths of an inch perhaps ?

What are you using to measure, a DTI - have a look on the dial to see what the divisions are.

Bob

As you say in the last paragraph and silver solder the nuts in place.

Over the past few months, the Stop `Start function of my Renault Clio 4 had stopped working with a fault message displayed on the console.

The car went in for its service and I happened to mention this "fault". The garage rang me to say the battery was on its way out and the car's logic had disabled Stop Start - did I want a new battery ? They quoted a price which I accepted. The battery was an original and just under 8 years old, so its been a good battery in its lifetime.

I have just paid the bill - no great surprise however attached to the bill was the battery test printout:-

48% Health of battery

47% Charge of battery

12.26 volts at state of rest

Perhaps I should have waited to replace the battery and used up a bit more of its life, but as batteries can fail when old, and living in the countryside, thought it wise to replace it. I doubt I will buy another one for this car.

angle grinder fitted with sanding disc. Test correct depth of the scallops by putting marking blue on buttocks and sand away the high spots (on the seat, not on the butt....).

"Any thoughts on the cause or a good fix? PTFE threads?"

Certainly not PTFE as that is a lubricant.

Bob

Peter, not a good idea having the same stainless for both nut and stud as they can cold weld and seize together. Perhaps not at the loads we put on the threads but once you go up in size, its a definite no-no. I worked at a lab testing high pressure steam stuff for CEGB, and there was a steam chest where the cover was held in place by about 40, 15mm bolts, the fabricated chest was the same stainless as the bolts and more than half had to be flame cut off. It took ages to clean the fan off afterwards !!

Bob

Yes, but look at all the new shiny kit dentist's have - Costa Bundle. Would you go to a dentist that had an old honeypot full of Detol to sterilise his probes and stuff and an old cream angle poise for a lamp and not to mention a drill powered by a sparking motor and 10 feet of frayed cord.

No you want to see the most up to date kit, an assistant that looks gorgeous and no pain. Someone (You) has to pay for it.

For Michael's "education"

I have made 5 of these reamers, different angles etc. Just harden the silver steel and let them down carefully with a gas torch. For one offs they seem fine, probably need to touch them up on a diamond stone every now and again if making multiples.

Bob

John, when making the injectors, there are tapered holes in the cones. These are reamed with home made taper reamers. I can only assume that the author was grinding a piece of hacksaw blade to make a flat reamer however these reamers are very small and some cones are drilled with a number 80 drill 0.0135" dia being the small end of the reamer.

My long case clock (1769) has a thin strip of brass riveted to the wings. It doesn't look like it has been replaced in its lifetime.

Bob

How about a nice old "French Curve" Not that I would donate, but I have all my Dad's curves for wing profiles etc in the 1930s. These were cut out of perspex and made in the workshops.

Bob

Another thing, why don't the two halves weld themselves together at white heat ? Mystery.

Update, just been watching the YESTERDAY channel where they were repairing large decorative cast iron panels on a bridge in Edinburough. The panels were removed then the temperature of the panel raised overnight to 600 deg C before oxygen acetylene welding.
