Help with drawing a part

[PixMan]

Here's the bronze I got in exchange for the cutter and inserts I wasn't using:



I'll be ordering an insert for the external Acme thread, borrowing the holder from Russ and making the screw first. Once that's done, I'll grind the internal threading tool and begin making the nut to fit the screw. Probably get to it next weekend. I hope to have them done and shipped off to Darren so he can have them by the end of the month. It can take a couple of weeks to get stuff like this shipped and through customs on both ends.

Thanks Ken, I'm happy to reimburse you for the things you traded. I'm looking forward to seeing one of those chunks of bronze turn into a nut

Ken, does it have to go through U.S. customs when going to Oz?

I have no clue. In today's world of suspicion I just assume the position. Err, I mean assume the worst case scenario. The last time I shipped a couple of boxes, one to Darren and another to a friend of his, it did take about 2 weeks and perhaps a couple of days to get there. Other times, just over a week.

I've never really thought about outgoing inspections. I know there is a form to fill out but never thought much about what happens after that. I read about the Joint Strike Fighter technical docs that were discovered being posted form the US to Iran, so obviously some things ring certain alarm bells and get opened.

Back to the original reason for this post, Kondia are going to send me the drawings for the feed trip bracket, as they are no longer having them manufactured.

• RC Running or Sliding Fits
  
• LC Locational Fits
  
• LT Transitional Clearance or Interference Fits
  
• LN Locational Interference Fits
  
• FN Force or Shrink Fits
  

Each fit has a class associated with it to determine the allowance which is applied to the hole and the shaft. I believe it's done a bit differently in the metric world, but the outcome is the same...

Hi Tom - I revisited these two posts of yours to look a little further into tolerances and I struck me as being a good topic for one (or more) of your videos. I don't recall seeing any for a moment (either your camera is frozen solid or you have run out of topics!).

That would be a good topic Darren. I did consider it at one point, but forgot to add it to my list. Consider it added now.

I'm still cranking the videos out at a rate of 1-2 a week. The latest ones have been project tutorials on for the carriage stop, with the most recent being how to cut the divisions on the thimble using the dividing head. Then there was the band saw brazing video a couple weeks back.

Everything else may be frozen around here, but the camera is still rolling.

Well Kondia emailed me the drawing for the feed trip bracket, so I have sent that on to Ken They also sent me one for the quill skirt, so I can check if the BP one will fit or try to make one. I might ask what other drawings they have that they will give me...

Darren,

I would get all the drawings that you can from them. Good reference material.

That is my plan Ed and I am working up to it. I asked about the elevating screw/nut so that I could check my drawings but these items are still in production, so (the rule is) I cannot get them (which I expected). However, my contact is going to ask about this. Either way, it sets a precedent that once they are out of production, the drawings are available, so it is a valuable learning experience (especially when combined with the feedback I received here).

It is also good to see the parts drawn, as I can see the way they drew them and the views they use. It certainly makes it more relevant when you can pick up the part and look at it and at the drawing.
