I've had the half size Burrell going for the third time today, all went well and we had an enjoyable day,

It runs better every time,

Pity it gets dark so early now.

I used RDG cutters to cut all the spur gears on my 6" Burrell traction engine, 6 DP, in both cast iron and steel gears, ....................No problems at all,

I would definitely use RDG cutters again.

Hello Mike, I've got a nice unmarked 8" Tom Senior rotary table , just like yours, I use it on an M1 mill.

Here is a page from the Tom Senior leaflet describing the various rotary tables.

Last Sunday I had my 6" scale Burrell traction engine running , It's taken 5 1/2 years, and was worth it !

It runs nicely and drives nicely as well.

Still a few things to finish off and adjust, but the end is is in sight.

Richard

Thank you all for your comments, I hope this has inspired some of you to have a go,

It's not that difficult, and you have something really practical that you can use at the end of it.

And you can make as many as you like, once you are set up for it.

If anyone makes any I would be interested to see them.

I ordered some stuff from MSC yesterday ( Thursday ), A very polite salesman, And paid by card, totalled about £35, he said it would be delivered on Friday ( next day ),

I had an e-mail confirming the order, and another this morning, saying It would be delivered by Craig between 10.06 am and 11.06 am

Craig the DPD driver arrived at 10.05 am.

A totally professional and courteous service,

I have no connection with MSC , only a satisfied customer

Yesterday my friend Dave came to see me and we bored out the cylinder of his 1930 Lister "D" type petrol engine,

He had aquired a 0.040" oversize piston, so we bored it to fit that,

Original bore size was 3".

We used my TOS FA3A mill , with a carbide tipped boring head,

This is the second one we have bored out, the first one was bored and a liner pressed in with a Churchill hydraulic press, and used the original standard sized piston.

Honing the cylinder,

Hello Steve, I like the straight knurl as well.

Hello Old Elan.

No plans for a production run, It was the enjoyment of making my own.

A while back I bought off ebay a "Rapid Original" QC tool post for my Boxford ME10 lathe, it came with one tool holder.

I thought it would be a nice project to make some more, I decided to make four more, here is a photographic record of how I did it,

The block as bought,

I had some steel offcuts, 3" x 1 1/2"x 2" in stock, the tool holder I had was, 3" x 1 1/4" x 1 3/4", so I used the Elliott 14 M shaper to reduce the blocks to size.

Then I had to machine the main part of large "T" into the back of the blocks, for this I used a 1" endmill in the TOS FA3A mill

Next I had to machine the "T" of the T slot with a 1"Dia x 1/4" Woodruff cutter, Each side of the "T" was cut in one pass, , 0.145" deep, at 250 RPM and a table feed of 20mm a minute.

Cutting the second side,

Now to cut the "V" slots, to start I cut two slots 0.093" wide into the blocks 0.300" deep, x 2.437" apart centre to centre, this was to give the points of the "V" cutter an easier life, I used a 4" x 0.093" slitting saw in a Tom Senior M1 horizontal mill.

Then I cut the "V" slots on the same machine using a 90 degree horizontal cutter,

After a bit of tidying up, I then machined the large slot for the lathe tool to clamp into, using a 3/4" 3 flute slot drill,

Opening out the slot to 0.850" wide x 0.550" deep

Next I made the height adjusters from 7/8" Dia, steel, with a straight knurl, threaded 8mm,

Here are the 4 adjusters completed,

Here are the four tool holders ,assembled , with 6mm tool holding screws,

And fitted to the Boxford lathe,

This was a nice engineering project, that will make the Boxford lathe a lot more pleasant to use.

I am quite a shaper fan, I think it would be fun to produce one of these tool holders entirely using a shaper, ( not drilling the holes of course ),

when I was at school ( early 1970's ), one of the first things we made in the metalwork class was a very useful screwdriver,

Handle was turned from a piece of 3/4" dia, aluminium about 5" long, knurled for the grip, tapered slightly towards the blade end, & drilled for the blade,

The blade was forged to form the screw end, then hardened and tempered, then pressed or loctited into the handle,

The handle could be as ornate as you like, grooves , knurling etc.

Nice video, but the subtitle translation is a bit iffy.

Hello Graeme W,

Nice to see your Boxford cutting an internal gear,

How do you work out the tool shape for an internal gear, and how do you create the tool shape accurately ?

I've cut plenty of gears using a commercial cutter in a horizontal mill,

At some point in the near future I am going to have to cut an internal gear, so I am interested how you achieved it.

Sam, it's a Colchester Master , 6 1/2".

A connecting rod for a Gardner gas engine

Thanks Maurice, thats interesting,

Richard.

I've just aquired a set of Clarkson castings for this engine and wondered if any one here has built one,

What I read on the internet , some one says some of the castings are iffy, and the drawings could be better.

What does anyone think ?

Richard.

Here's a picture of a 30" Elliott I used to use a few years ago, cutting dovetails in a 9" cube of EN9, no problems at all,

Nice paint job Rik, was it sprayed or brushed ?
