Its a bit like car insurers not reducing premiums whilst the car is effectively in lockdown.

Thread: Hello Chuck

Ever used a Jacobs style chuck and trapped a bit of flesh between key and chuck - That hurts !!

Thread: Threading myth .... busted!

For the last year or so, my threading has not been up to scratch, single point screw cutting most often cleaned up with a chaser. I needed to change some gears the other day to get 19tpi yesterday and noticed that the 56 t gear (standard) was actually 58 t !!

And all that publicity about older drivers not being competent - 60 year old driver calmly brings car to rest !!!

Do you reckon the owner of the bike will own up to this ?

Nice one (3 phase) sitting on eby at £530 3 days to go... Higher spec etc etc

Gives you an idea of what you could get

Odd things, looks like there is a collet drawbar, the gear setup is strange and it looks like a 100 / 127 gear set (but not in the right combination) with allows an imperial leadscrew to cut metric threads, but you need some more gears (probably 5 more at £40 each), no reverse on the motor, the half nut lever is 180degrees out of position ?? are the external 3 jaw chuck jaws available otherwise the value of the chuck is reduced. Are the Dixon tool holders there ??

For a beginner I think this would be too risky. Agree with Andrew on this one

Lee, if you don't know about this link, you should have a look. All dimensions for Austin 7 engines, crankshafts etc etc.

Electric spark etch ?? or todays technology, laser etch. Would electric etch be preferable to chemical etch ??

Jigsaw, goggles and ear muffs. Use a bit of cutting oil prolongs blade life. I have even cut 1/4" steel plate this way just with a good old DIY Bosch jig saw and a metal blade.

Thread: Overheated Drill
31/08/2021 15:55:23

That was a pretty small drill for that application. The cost of drills has fallen dramatically since the 1950's and a serious DIYer would have a smaller variable speed battery drill, a small mains hammer drill for medium work and an SDS hammer / chisel drill for heavy work. Of course you will need some SDS drill bits but many SDS drills come with a "Jacobs" chuck which have an SDS male fitting.

Well Geoff, there is your first project ! Make you feel good when you have made one.

Thread: Cutting Brass Sheet
31/08/2021 14:07:56

Seems strange, but you can score metal several times to cut a line. Look up metal scoring tool on the net. Mine has a small carbide point and have used it to cut zinc sheet mainly, but also some 0.5mm steel sheet for the old 2CV car.

Hi there Lee - That will be some project ! Which engine is it, the magneto one, the 2 bearing crank or 3 bearing.

Removing the crank can be difficult, made easier if you can tap the rear bearings off the crankshaft BEFORE removing the crank itself.

Most of the original dimensioned drawings for these engines are available on the 'net.

Let us know more as there are several A7 owners on this site.

EGA - Print to PDF is part of Mac OS, also handy is Cmd+Shift+3 this takes a screen shot and puts into a new file on your desktop as a .PNG file. re-name it as a JPG file and upload it to your albums on Model-engineer etc etc.

Thread: To Cap It All

Ps, if Martyn would like to PM me, I have both cast cored bronze and some scrap marine bronze that would make the 1 1/2" diameter threaded portion here in France.

Jason, the originals had a thin top hat machined in brass which formed the thread and cap. The outside is knurled and a Bakelite cap bonded to the brass. I think Martyns best chance is to find a bit of brass and if lucky enough a big brass nut with enough meat to turn the internal thread, machine off the hexagon, crewcut the thread,silver solder a thick plate onto it, and machine the cap. Expensive exercise but it would be the joy of achievement. Chance of finding a 16tpi thread here in metric land would be like finding hens teeth - BUT good luck.

Brass stop ends 2" BSP may be a possibility (2" BSP 2.347" OD) but the finished wall thickness may be very thin or non existent.

Or possibly something like this ??

Solder stop end

What vehicle radiator ?? British / American will use TPI and most others will be some form of metric generally.

37mm is about Austin 7 size. which I believe is 1 1/2" and the thread would be Whitworth form and any TPI the maker chose.
