I have just purchased a Boxford Lathe

[minimutly]

If I have to fit an alien pressure plate on a car flywheel I will machine an indentation exactly the diameter of the plate, then take the flywheel out of the lathe, spot and drill the dowels and the clamp bolt holes to be tapped.
The register/indent can then be machined flat before balancing.

I still need to get my head around fitting this reverse switch too, I dont know what I am so worried about. It will make life so much easier.

Thought you'd already crossed that bridge...

all the bits are here ready I am still trying to get my head around the wiring of it all
I must do it soon the winding out of taps by hand is doing my head in as is the left hand tapping by hand

 

[123hotchef]

Switch fitted and working took some more head scratching

 

[123hotchef]

Time to put it all back together.

 

[123hotchef]

Treated it to a new belt too.

 

[123hotchef]

Man I should have done this sooner so much easier to tap now.

Once tapped with the power tap it feels a little stiff is it a good idea to use a second to finish the job

Good work. I assume you finished the chuck collar? I don't recall seeing the finished article.

No the chuck collar is still work in progress. I got tired of winding the rh tap out by hand. Then I thought I would try the lh tap and it is fine

 

[123hotchef]

Is this to fast for tapping?

 

[Seadog]

Not if it works.

 

[123hotchef]

Not if it works.

it works ;-) one thing is the threads are a little tight do you normally finish the job of with a second tap?

 

[Windy Miller]

I’d personally do it a lot slower for fear of breaking the tap, but maybe I’m just a pussy?

ha ha I dont know lol

I thought machine taps were finished thread size @Hood will know for sure .
If too tight run a bottoming tap (3rd cut) down it. I would do it by hand as if it bottoms in the hole it will probably break.

 

[123hotchef]

I think it may be worthwhile for me to let the adjuster cool down after boring out before tapping that could be why they are a little tight.

Machine taps are full size, as are hand taps in reality, just hand taps have a varying tapered lead on the three. You do get what they call serial taps, have a set myself and these are different diameters, can be handy in hard materials.

Regarding the speed, doesn't look too fast for me but depends on the material. Are they through holes or blind?
