My next project. I just got done drawing it up. I looked at the one from CarveOne located here. It is really nice. I wanted to say I drew my own. I found a high definition picture of a one and started making up the vectors and this is the V-carve toolpath preview it made in Aspire.

Finally decided to purchase Rhinoceros. Still a lot to learn but I am pleased with the purchase.

Fox Sat 25 October 2014 00:36

Congrats, it's a good buy imo. You have a lot of bang for the bucks. If you need any help let me know.

Good price for an very good software. and much free tutorials on internet.

pblackburn Sat 25 October 2014 18:23

It does take some retraining but I have been able to draw some nice stuff so far. I really am only scratching the surface. It is very friendly with Aspire so that pretty much made the sale with me.

Working on this at the moment. I need an area for gluing. I saw something similar to this online but it was built into a larger table with clamp storage underneath. Unfortunately space is a premium to me, so I need something that breaks down. This will completely come apart and store in a minimum area. I also do not need all of the cutouts installed, only what is required for the piece. Allows clamping from both direction with pipe and bar clamps and allows for a board to be inserted through so you can use a hold down to keep the board from lifting under pressure if needed.

Pete do you have a site that actually has one of these in use. Just having a hard time visualizing the setup. Thanks.

Russel,
I can only find the image. I think it was in a article of Fine Woodworking originally.
I have 1/2, 3/4 and bar clamps with both standard and extended reach.

One side the standard clamp can set down in the relief that looks like a castle.

The extended reach be put through the holes/slot designed for it. (I had to only have access to glue from one side before so I though this would be a nice feature)

The large oval is an addition from another image (sorry can't find it). This guy used those on his glue clamp table to apply downward pressure on the wood when gluing to help prevent lift from deformation of the pipe. I liked the idea so I drew it in.

Now that's just plain cool.

Regnar Mon 27 October 2014 02:10

Not going to lie.....I will probably be stealing the ideal.

pblackburn Mon 27 October 2014 04:21

You want the drawing. I'll send it. Not much I won't give away.

sailfl Mon 27 October 2014 05:22

Pete, I will take a copy.
Thanks

pblackburn Mon 27 October 2014 05:41

This link will provide a dxf and eps formats in a zip file. Enjoy!!!!

Thanks Pete

pblackburn Mon 27 October 2014 08:07

No problem. Anything I post on here that you would like, just remember the old saying. It never hurts to ask.

darren salyer Mon 27 October 2014 09:16

That's very generous of you, Pete. I'm sure I'll be building one as well.

servant74 Mon 27 October 2014 11:05

That is awesome. As others build this, how about some pix too!

Regnar Mon 27 October 2014 11:17

Thanks. I took a copy as well. This with some camber cauls and you should be set with most glue-ups. Thanks again.

bradm Mon 27 October 2014 19:00

Thanks, Pete. Pleasure to have you here.

Hans Tue 28 October 2014 03:58

Thanks, I also took a copy. I'll change it to metric

pblackburn Tue 28 October 2014 13:43

Hans,
When you are done, send me the drawing and I will update the zip file.

Several posts from Tokamak's thread (John #121) answered a problem I had for my inputs. So I built an optocoupler board. I was using a relay for switching the dry contacts.

Working with something so thin you have to have a true surface. So I machine off a section of wood, set my calculated offset for my tool zero touch off probe.

About the device and what I would recommend. A small vacuum box would be really handy. Practice on a bread board first before cutting and assembly. I made a mistake and was able to repair the circuit with little effort. I am updating the drawing now. This layout gives both a visual indication and a signal change. I like to use 24VDC for all signal as it is industry standard. I thought this would be helpful in troubleshooting. All chips are in an IC socket for easy replacement.

Fox Sun 02 November 2014 02:26

That is exactly how mine looks, good work

Tom Ayres Sun 02 November 2014 05:40

Hey Pete, with me not being an electronics guy, would something like this work for switching 24v panel lights from a 5v signal (like from the bob)?

pblackburn Sun 02 November 2014 05:52

Personally I would stick with a relay based design for switching a resistive load versus using a transistor. This is from more experience with PLC cards that are transistor based failing miserably where the relay out cards will not. Sure you can make a board that would be able to control a PCB mounted relay for switching a load and it may be worth while to prevent something in the future but most of the time the relay windings will open and not go to ground. I have seen snubbers cause problems with degradation over time with the function of the relay also. So the choice it yours.

pblackburn Sun 02 November 2014 06:44

Looking back through my thread, I see I forgot some information about the spindle repair. I ended up purchasing the bearings from a company called GTI Spindle Technology out of Manchester, NH. They have great customer service. I found them while looking on Ebay so I gave them a call and now I am glad I did. An option for anyone State side that is in need of bearings to repair a spindle.

darren salyer Sun 02 November 2014 06:48

Good to know Pete. Thanks for sharing.
