Thread: Angled HSS toolholder and tool sharpening angles
17/09/2010 20:51:28
Hi Guys
I have been using carbide tipped tools but in the search of a better finish I am going to  try HSS.
 
The HSS holders I have are angeled up about 20 degrees from the horizontal. Is this a standard tool holder?
Is all the standard published sharpening data re angles etc related  to a horizontal or angeled tool holder.
 
Assuming that my tool holders are non standard can someone suggest
sharpening data and any other 'work arounds'
 
Thank you for your interest
Regards
Frank

Hi
I am trying to thread an 1/8" shaft with a 5ba split die. Checking the net this seems to be correct, I just cant get the die to start on the shaft. I made the die holder myself which is a very snug fit on the die. I think the problem is probably that it too tight to allow the die to 'spread' to start threading. My question is:
What should be  the actual diameter of of the die receiver on the wrench when the diameter of the die is 13/16" 
Looking forward to your help
Thank You

Hi

I am building a Stuart V10 steam engine with little difficulty till now. The problem is to drill the initial 3/32 hole in the valve chest for the valve shaft. This has to be perfectly aligned in all planes or the efficiency of the valve is greatly reduced. There is no problem in drilling the initial part of the hole in the bottom  of the chest however this drill has then got to continue a further 25mm aprox  unsupported before drilling the upper hole in the chest to support the shaft, any error is therefore amplified. It is impossible to  punch a guide hole  at this point so you are relying on the drill not to wander. The guide suggests the  point of entry be filed flat to minimise that danger but even then it is a bit of a hit or miss affair.

I tried drilling from both ends as an experiment with a view to plugging the entry hole at the top of the chest. This was only slightly more successful.

I am sure there are plenty of people who have successfully built this or similar engines and I would be grateful if you could offer any suggestions

Thank you for your interest

Regards

FS
