Hi Bazyle

I will have to check against the above if I get what you mean.

Yes I'm on the yahoo group but finding anything with the search function is hit and miss I find.

Agreed and lesson in not trusting 'permanent ' marker again. Scribed line across the delrin cams will be the way to go.

Seen the link above but the photo's and videos on the gearbox don't show the cam as it's hid behind the selector forks and also they dont mention how they relate to each other.

I have seen one video on you tube that states selection 1 has the first gear made. No further details.

I'm looking at a last resort of a mail to the 600 group to get some detail.

Hi all,

Posting here for a bit of help as a search of the internet hasn't turned up what I'm looking for.

When I got my Colchester student 2500(metric 6mm leadscrew) the gearbox was seized which is the same as the M300 problems. I stripped out the four cams carefully numbering them up after a clean with solvent to remove the old oil and residue.

Unfortunately I didn't get back around to reassembling the gearbox until last weekend after a gap of 5 months the solvent which was left on the parts had dissolved my permanent marker and now I'm guessing which gear is supposed to make in each of the 8 positions on the rotary knob?

Looking from the back with the lead and feedscrew to the left and cam 1 to cam 4 follower left to right. I have the 8 gears (again left to right) meshing in with the selector knob position as follows 1-2-7-8-3-4-5-6. Would like to confirm this is correct?

The selection was vague and taken me some rotating about with the selector to make the gears line up in each of the detent positions.

I have tried the harrison m300 Yahoo group but it is very quiet on there.

Many thanks for the info and help in advance guys

Damian

Thanks all for the replies

Great picture Nigel

I have some 4mm brass sheet so will go with making some. At least the dividing head will get some use on the little mill.

The originals will have been lost due to a careless previous user of the lathe. I'm in the process of a strip down and clean so the lathe is in bits.

I did know it would be a long shot finding them on their own. There are some on ebay but they are odd numbered ones.

Hi all,

Having recently acquired a modern type Colchester student (1997 vintage) I have noticed I'm missing the thread dial pick gears except the 16 tooth one that's mounted on it.

The other gears are 14T, 18T, 20T, and 22T.

Other than the 600 group (probably a fortune) does anyone have any or know where to get any?

Cheers

Damian

Cheers Clive

The nut (battered nyloc) that came with it had a plain washer underneath it so no such arrangement. Looks like when I get the lathe up and running I will have to make something up to suit.

I'm a way off so it will probably be the end of August before it's all back together.

I have just been wondering about the top hat bush during the rebuild of a boxford 11.30 lathe. I never noticed when I stripped it but now I have cleaned all the parts and started to re-assemble I've noticed this in the photo below?

Should it really be that much of a sloppy fit?

Damian

Thanks for the suggestions guys.

In the end I've gone for paragon again as it was easy enough to work with last time. The difference after the dreaded VAT and shipping was £18 so not enough to warrant changing.

I'll see how I get on with it.

Agreed

Any quality steel producer will sample the scap going into the mix and alter the mix to suit,also sampling during the melting process to refine the steel. I doubt this is the case with most mild steel that enters the country from china.

All steel should have a data sheet which gives composition info

Yes price wasn't really what I wanted to discuss but whether anyone had used their products and what they thought of them?

I'm wanting the specific colour and enamel paint that will do the job. As I stated I've used Paragon/craftmaster and thought the enamel paint o.k. although a little soft. I'm no painter only an amateur at best.

I've heard tractol mentioned a few times but as far as I'm aware they only have a set colour range.

Still plenty of rubbing down to do but whilst summer is here ( loosely stated!) I want to get the bare metal painted.

Hi all,

I'm just in the process of rennovating a boxford Industrial lathe and have been looking around for the correct paint colour ( fern green I think).

I've used paragon paint in the past but they are expensive. I've had a quick search on the web and wondered if anyone has used these?

Acron paint

Seem good value

Already posted but The Lunar reconnaissance Orbiter shots on this page make it pretty convincing for me

Morning all,

I have had two people say there is a tapped hole for an M16 eye bolt. I have one of these (correct one rated at 0.8T).

Many thanks for the help
