Hi Pete, you show the speed table on your head. I have a series 1 J head and the speed table has twice the number of speeds, two high and two low gear speeds for each belt position. I have not been able to run the mill yet, so can't tell what's different. Any ideas? It's the 1hp motor, not variable.

[mrpete222]

@hoarp001 Does it, or did have a 2 speed motor?

Thanks for the tutorial on boring and no I didn't find it Boring. I actually found it quite informative. I noticed on one of your boring bars that you said also can be used in a lathe that it had three points. I'm assuming that means as one point/cutter gets dull you can rotate to a new cutter/point. Is that true, does that type of bar have a specific name? Thanks.

[mrpete222]

@riten2 Yes, its an indexable carbide boring bar. It uses inserts.

You can get that Quick Clamp on e-bay from Discount Machine Shop: they are made by Shars

Can you do a video on how to bore in the lathe?

Again, thanks Mr.Pete.

[MrSteamdog]

[Rustaholic777]

Where is the next video about drilling the holes around this part?

I really wanted to see that one.

You are a very good teacher.

"Bridgeport" one of the most universal, and useful of machines in any busy toolroom. I couldn't even begin to tell you how many hours I have spent working a Bridgeport, I even managed to turn one over once trying to move it, but thats another story.

Best machine in the toolroom by far....

I can also see by your narration you know your stuff, thats a compliment from one engineer to another.Keep up the great work and long live those engineering skills.

Thumbs up from England :-)

@mrpete222 Just had a look at my speed table, It goes from 67RPM all the way up to 4600RPM!!!

[hoarp001]

@mrpete222 We wondered this, the motor that's on there has got a damaged barrel switch, so I can't tell. Dosnt look like it's two speed...
