Thanks Steve, I'll order one. Good idea Pete, maybe trim in aluminum with rivets or something.

Tom Ayres Wed 10 April 2013 20:01

Painted the box blue (of coarse) tonight. I've got a lot of blue to clean up, I got in such a hurry to see the first bit of blue on anything that I forgot to lay out some cardboard or paper, oh well, let dry and sand, tah dah!

I ordered Bearings from Rick at Superior Bearings last night. I've made necessary mods to the skate for the rails, just waiting on bearings. I should be able to do a little more welding this morning to complete the side rails of the base, just wanted to make sure measurements were correct before proceeding. I really need to set up Flicker so I can post these pics.

If you go with Flickr, after you sign in and have photos uploaded. Click on the picture you wish to share from your photostream to show only that photo. Directly above the picture is a button labeled SHARE. Click on it and choose "Grab the HTML/BBCode". Click the radio button for BBCode and choose the picture size you wish to use. Then copy the code out of the text box and it can be directly pasted here. You can edit it if you wish or post it as is. By editing the code you can remove the link text , remove your username which is a link to your photostream or change the link text to something other than what is the name of the photo.

Hope that helps.

Thanks Pete, quite helpful. I'll give it a go this afternoon.:D

Tom Ayres Sun 14 April 2013 20:14

Welded the Y car this morning. Everything square, flat to the table and ready for a coat of primer and paint.

pblackburn Sun 14 April 2013 20:17

Sound like you are making headway. Keep on trucking.

Tom Ayres Sun 14 April 2013 20:22

Waiting on roller bearings from Rick, should be here by Tuesday. That's when the rail grinding starts-That's when the fun starts.:D

pblackburn Mon 06 May 2013 18:40

Tom, how are the rails coming?

Tom Ayres Mon 06 May 2013 19:14

Well Pete, Never got to them, the wife has me doing other house stuff (like finishing the bathroom remodel). I did however get the spoil board bolted to the cross members ready for welding. I'll have to finish a cabinet job before proceeding further though. Funny how the customer wants their stuff when you ignore them too long.

pblackburn Tue 07 May 2013 14:23

That last part was worth a laugh. Just seen a lot of people start and stop when they get to the rail grinding part.

Tom Ayres Tue 07 May 2013 16:50

I'm definitely ready to do the rails, got the skate set-up, shop is somewhat clean, got just about all the hardware needed for assembly, picked up the spoil boards last week (5x12's about killed me), got the teflon washers from James, been hounding my machinist about the bushings and bearing idler stud (zero cost so I can't complain) but just gotta keep'em happy. Planning my purchases of the control box and making final decisions on steppers and whether I should just use one of my 3.25 hp PC routers to start or just wait until I can afford a spindle set-up. What would you do?

bradm Tue 07 May 2013 17:18

Tom, I used a classic PC 690 1.75 hp to start; I also used it to cut the 1/2" aluminum (in .05" passes) to hold my spindle. If you're going to be ramping up slowly and learning the machine, I'd go with the router and upgrade when you're ready - you'll know for sure that spindle and VFD noise aren't the issue while you debug the table, and you'll get a good feel for the limits of the machine. However, if you're looking to get to high production levels fast, and willing to deal with the extra complexity, then go right to the spindle.

My little router taught me a lot about how to make multipass cuts.

Tom Ayres Tue 07 May 2013 17:36

I think I have 3 of the big PCs here at the house and of coarse the 'classic 690'. I hadn't thought of using a router to cut the bracket for the spindle, good starter project. And you are very right about not introducing another possible bug to fix, good call Brad. I would really like to get the spindle though, but I didn't want to buy additional boards when switching.

pblackburn Tue 07 May 2013 18:30

Adding a spindle will not require anything but a 485 converter using the serial port on your computer. It does require a bit of filtering, well quite a bit. WC spindle is nice for better dust containment and management as there is no fan to fight with your dust collector. I started out with a PC7518 but that is what I had around the house.

Tom Ayres Tue 07 May 2013 18:54

Now when you say filtering, does that mean chokes and isolated grounding, etc?

pblackburn Tue 07 May 2013 19:36

Yes. RF chokes, ferrite cores, line reactors, etc.

Tom Ayres Tue 07 May 2013 20:03

Also, because I would be using the serial port to control the spindle it would be safe to assume that Mach 3 would control that configuration setup? By-the-way Pete, my wife is from Blairsville near Indiana, Pennsylvania, 1 hour outside Pittsburg. Where are you?

pblackburn Wed 08 May 2013 04:57

Bedford, 2 hrs from Indiana, Pittsburgh and Harrisburg, 1 hour from Altoona and Cumberland, MD

Tom Ayres Wed 08 May 2013 17:59

I think my header "Going to start the rails" should add: "After my wife releases me from indenture..."

pblackburn Wed 08 May 2013 18:49

I think all of us that are married would have that title.

swatkins Thu 09 May 2013 17:56

Tom, I've been saying that for three years!

But I am sooooooo close to freedom.. http://starnetservices.com/picture/house.jpg Only 70 more doors to make and install and then on to the base ! :)

Tom Ayres Thu 09 May 2013 18:21

Got the seal for the control box door today, had to wait to fabricate the door until after I knew what the seal really looked like...Oh that's right, I can't until I can show some progress on the bathroom:rolleyes:, lol

Steve you have no idea how long I just stared at the forum before I decided to 'make my move' and start building, it took a lot of premeditated calculation...and here I wait again.:(

pblackburn Sat 11 May 2013 12:42

Tom,
I started thinking about a cnc router for my cabinets in 2007 when I was building my home but not on the size of a Mechmate, only large enough to do doors. Didn't have the time then as I was the one doing the building. I stumbled onto this forum in 2010 but I had to build a stone retaining wall around the home with rocks I removed with the excavator in 2007, 2011 I had to make a yard. Finally in November of that year I was able to get the wife onboard with building a CNC router. It will make her cabinets so therefore it was okay. She has left me play with it long enough to learn it and now she wants the new kitchen done. I would like a garage and the only way to get it is to finish the kitchen and dining room. Small price to pay but if they are not happy, neither are we.

Tom Ayres Sat 11 May 2013 13:26

Well Pete where is your MM now if not in the garage?

pblackburn Sat 11 May 2013 16:11

Basement is at ground level for first third of the home with 9'4 ceiling. House built into the hillside. My other home on the property is condemned and is slated to become the foundation for the garage (there were 2 houses on the same property when I bought it, one good, one not so good). This is why I harp on the importance of dust collection. I try to capture even the smallest particle which is impossible. I use ventilation and air exchange to assist air quality where the dc cannot go. That is also why I went the bolt together route to fit out my 6' x 6'8 doors when it makes the transition which I hope is next year.

Tom Ayres Sat 11 May 2013 19:34

Good luck with the garage, I'm sure it'll be a blessing. I started woodworking in my garage then built a small shop next to the house (30 x 40) after the wife complaining about the dust. Then moved my business into 6500sf two years later, then into a 11750sf. Now I'm trying to get back to the small one and a half man operation again (so much less headache)

pblackburn Sat 11 May 2013 19:48

I now about the dust and I try to maintain a minimum. The biggest helper was the wc spindle with the dust shoe. It collects more than 99% of the dust now. Don't smell it or taste it and flashlight test is good but I still added cross ventilation to be safe. Making one cut with my 12 compound miter saw makes more dust than a sheet of plywood being cut for cabinets. I have the layout of the garage, just need to start and I was informed kitchen is first. I will be in an area 26'x30'x9' when it is finished.

Tom Ayres Sat 11 May 2013 19:54

Very Nice! I don't have a dust collector here at the house, I look to find a deal with on-line auctions. Haven't really pushed for one because I want to make sure that the MM is built first.

KenC Sun 12 May 2013 01:32

ITs never too early to install a dust collector.

Tom Ayres Sun 12 May 2013 04:20

I understand the importance of dust collection and was planning a Bill Pentz cyclone set up. I've got the sheet metal but need to get the DC to know what size it will end up being, (based on Bill's calculations of hp and size of impeller, etc). I do have a fine dust filter system that I've used for years, works great. Gets rid of that pesky fine stuff fairly quickly that would otherwise not be picked. It'll all come with time (something I have a limited amount of).

KenC Mon 13 May 2013 04:10

Thien Separator is an effective & economical solution. all you need is to get hold of the biggest barrel you can put your hands on. 2 hours work tops.

Tom Ayres Mon 13 May 2013 17:14

I'll check those out. Do you have any references? I really enjoy metalwork though and look forward to building the cyclone.

domino11 Mon 13 May 2013 19:43

Tom,
Try this out. The Thien Cyclone Separator Lid :)

KenC Tue 14 May 2013 01:14

how I did it.

Tom Ayres Tue 14 May 2013 02:59

Heath and Ken, thanks for sharing. I was planning for the exhaust to be vented outdoors with a collection bin for clean-out. I had already made an area on the outside for a cyclone set up when I first built this building. (noise is a big issue for me, I want to be able to hear my grandchildren when I get old)(I already can't hear my wife :D)

domino11 Tue 14 May 2013 11:48

Tom, I think that is selective hearing. :)

Tom Ayres Tue 14 May 2013 17:00

Oh really...;)

pblackburn Tue 14 May 2013 21:20

I think the proper answer is "Yes Dear" :)

Tom Ayres Thu 30 May 2013 19:21

Received the steel for the z plate today, think I'll secretly layout the holes and countersinks. (sssshhhhhhhh) Also picked up some sanding disks to grind rails and ordered 36' of rack as well. had some of the last bits of steel delivered last week to the shop, again sshhhh....

On a good note, I did manage to make the stair hand rail for the house, made the wife happy, so there.
