The bore of the cutter holder will depend on method of manufacture, if it's reamed to size it may be a little under, especially if an H6 reamer is used, the 5.96 should be OK, but you may need to heat the holder to engage the 6mm diameter cutter it should be usable and likely have less run-out than the other cutter.

You say both blocks are ground to the same angle but do they match if 1 block is turned by 180 deg, ? if they match perfectly which ever way the pair are used it means that both sides of the V are ground to the same angle, rather than 1 side ground 47 and the other side 45 for your estimated 92 degrees.
If the sides are ground at different angles you cannot set-up by clocking between the V surfaces to find the centre.

I believe Tuff Saws packaging includes a tip to slacken off tension when not in use, if you do slacken off make yourself a label to hang on the saw to remind you to tighten the blade before use, or like me you will be refitting the blade.

Both the .5hp and the 1hp motors for Myford on the Tesla site are vented motors, not the ideal choice for a machine that's making swarf and chips, better to have a totally enclosed fan cooled version IMO.

If you are cutting with used cutters the top of the flutes will no doubt be in better condition so more likely to cut cleanly.

If you always mark with "machine parts for UK deliveries" I'm surprised they don't come back to you.

Suggest you try a cut across the same material but at the opposite side of the vice, check if you have any problem after 1 pass, if so do a finish pass to see if all is well. If the taper is opposite to the cuts made on the other end of the vice it would point to the tram is out.

Is that round bar ?
You may be able to buy a piece of hardened rack that could be fixed to the bar, would save the hardening process.

Plenty of choice on ebay for 8A fuses, slow, medium and quick blow, glass or ceramic bodies.

Perhaps reducing the DOC will help also using a lubricant is another benefit.

8mm diameter.

Could be a location dowel ? reason I suggest that is because the screw fixing points are counterbored and it's very unlikely a skt cap would be damaged in that use.

They must be something special, thought 5/8" BSF was 14 TPI, strange.

Old models cycle front wheel axle size, 5/16"x26TPI, just making a shaft with an M8x1.0, so close difficult to tell the difference with thread gauges.

Unless there is some good medical reason for wearing those chunky looking gloves it would be safer when using the lathe to remove them, well at least when the spindle is revolving, or perhaps you do ?

Hi David

I am not certain but guessing that on the full size any such pipes would be clipped at one or more points to avoid damage by vibration, same with fuel lines and electrical cables, not good to have any of those damaged.

Nice work on the engine.

Sounds to me that you need someone who knows what they are doing to be hands on with the machine, may cost a bit but at least you will be best advised.

Emgee

They will be 25.9mm diameter threads, much bigger than the 3/4" you wanted.

Do you keep the moving roller down tight to the fixed former when bending ?
Do the grooves make a complete circular shape equal to the pipe OD ?

If the above lines are true then with annealed tube you should get good bends at the radius required.

I was informed by the Machine Tool workshop where I bought the machine the spindle taper was an R0, similar style to R8 but smaller diameter on all dimensions, my machine came with a Clarkson collet chuck fitted to a suitable taper.

Herbert 0V is a great vertical milling machine, very heavily built with excellent quill on a massive spindle. Plenty of height table to spindle to accommodate rotary table + part for machining.
