Hi Bill

SL milling table is 127x76 11mm thick with 3x8mm Tee slots that are 3x13 at base.

There are 4x6mm fixing holes counter bored 11mm diam for 6.9 depth, starting at 24mm from end then 50 from end (so 26mm centres)

2nd row 25mm centres from those above. So 24x26mm rectangle with holes at corners.

Will PM you about a drawing.

Is there any means on the driven pulley to engage the pulley size needed for the job ? the remaining gear would just rotate on a bearing if the drive pin was removed.

Perhaps the battery issue is only on models that have more functions such as later models with ABS function ?

Can the Wixey check and indicate a level surface or is it always relative to the last Zeroed setting ?

As others have commented makes a change from usual colours, everything on your engine looks crisp and well finished, congratulations.

Hi Tim

Good even coating to all areas.

What spec are the toolholders made from ?

Joe, I would use a 1/4" and reduce the rpm to halve drilling speed, using coolant (spray or brush) for both ops.

You may have to get it from an on-line supplier by post, black and/or bright mild steel are not a good place to start machining steel, as many said EN1A or with EN1APb would provide an introduction.

If you are in the UK get some EN1A steel, this is free cutting and a good place to start.
Some mild steels will be difficult to attain a good finish, they tear rather than clean cuts.

Nice looking fins Craig, all look very crisp.

Search for some PCD inserts, some may cost £30 each inc post but they are available at £10 for 2 delivered from some sellers, those from China may not be the same quality as the more expensive but I find they are super inserts for high silicon and all tougher aluminium alloys and give super finish even when using fine finishing cuts.
Available in different styles and nose radius but I tend to use the 04 rad for finishing.
CCMT060204 PCD, DCMT070204 PCD, VCMT110304 PCD.

What type and rating of fuse are you using ?

Emgee

Manny, I believe a small air brush kit would be capable of spraying the parts mentioned.

Emgee

Hi Manny

If I had a machine with that sort of accuracy I wouldn't be looking for a modern equivalent.

An excellent method to provide positive clamping with instant release, I first used it on a Dore Facing and Boring head to retain the tool, it was the method described on the plan.

Used it a couple of years ago to lock a rotating turret type 8 tool toolpost to a stop on my cnc lathe.
Tool turret pictures in my album.

Like Dave W I didn't find an electric paint sprayer did a very good job, exceedingly wasteful of paint and made a mess everywhere, but that was spraying emulsion paint 45 years ago, no doubt they are improved these days.

My Bantam gears are 16DP.

Many years ago I had a 5" Victoria dividing head but the drive on that had a single keyway, not multi spline as these gears.

Emgee

Hi Mike

Could be Colchester Bantam, if you count the teeth and measure OD and post the figures, the DP can be calculated which will help identify which machine they will be suitable for. Dimensions of the centre and splines will also be helpful.

Just used it tonight for the first time adding captions to a picture, OK for that purpose.

Hi Craig, what is the purpose of the recess in the front face of the prop driver ? I would have thought you need as much driver to shaft contact as possible with the method of fixing the drive to the shaft, also increased mounting face area for the prop, IMO a key would offer more security in operation and if also on a taper ensure concentricity of the drive system.
