Interesting to say the least !
Appreciative of you taking time to share those photos.
When time permits, post some pics of it while working and you smiling cause it’ making you money :D
Congratulations, Robert ;)

Johan the cutter is homemade, it is a chain saw chain (smallest you can buy), the disc I turned on my metal lathe.

Thanks Heath

Robert and others .... next time I turn something I'll video.

I remember someone posted a map of all cutting MM .... can't find it .... anyone know where it is. Thanks J.R.

JR,

Here's a link to the Post with the KMZ file that Gerald was kind enough to extract for us from Roadkill 321's original work.

have purchased 5 9802 motors from Deitech.
 

BTW JR…. I'm curious :p
Why changing your motors to those new Deitech !?
Robert ;)

Robert I'm collecting for machine #2. :D

No3 if you include the lathe, you're getting as bad as Sean now... :)

Alan,
All mine aren't under one roof! I only get to visit them.

Hello everyone, its been a while since I posted here but I read the forum on average once a week. I need some input from you guys. I'm cutting parts for a small business using 1/8" X 4' X 8' pvc (they supply material). We cut around 10 sheets every few weeks to a month. There are several different stock sheets, each sheet has around 20 pieces. Tell me what you think it's worth per sheet to cut this job. Thanks for the help .... J.R.

JR,
PVC extruded sheet cuts VERY quickly (1/2" pass with 1/4" spiral @ 280-400ipm) - and makes one heck of a mess. Just remember to wear a good filter/respirator mask if your in the little shop.

When I was cutting 3/4" PVC for cooler inserts at the ball field (to separate coke bottles), I charged 50 bucks a sheet to cut it, or 400 for the day if it was a large, repeatable qty.
It takes more time for clean up than it did to cut sometimes. Static cling!

Good luck my friend. Good to see you here.
Sean

Hey JR, was that your annual post to the forum? :) Great to hear you are still active!

This one is the 2nd post this year .... just to prove Gerald wrong :D.
Sean this statement really holds true .... "It takes more time for clean up than it did to cut sometimes. Static cling!"
I have been cutting for this customer 2 years now with no increase in price. I cut 1/8" and 1/2" thick material for $20 per sheet.:rolleyes: The customer wants no increase and I want/need $25. Thanks Sean for the input. J.R.

Around here a simple sheet cutout starts at $35.00

Thanks Darren, that helps. I need to know I'm being fair and not greedy.:)

Re: control box
Hello Guillermo. I am planning to build another machine. The current control box cools fine by pulling air into the box, this requires the box to be air tight. The new box will cool by pushing air (Gerald's suggestion) into the box so any small holes will just let a little air out, no big deal. The main exit will be an aluminum square tube large enough for all the Gecko drives to mount on the surface creating a perfect heat sink. One end of this tube will be open inside the box, the other will attach to the exterior of the box (maybe the bottom, to prevent dust from getting in when not in use). It will have an exit hole cut to match the inside of the tube. All air will exit through this tube therefore cooling the drives and the interior of the box (the air has to be filtered of course). I also plan to have one or two hinged panels for easy access to all components. I hope this helps ....... J.R.

Is this customer you are cutting the sheets of PVC cutting for them selves or their client. I recently had a discussion with my client and they are planning a price increase to their client in Dec. I told them I could wait but I need to see an increase.

I don't believe a $5 increase is out of order. You are cutting 20 for a $1 a piece. Your gas, electric, bits etc have gone up. $0.25 per piece in not an unreasonable increase.

JR I was paying $31.50 a sheet so $25.00 sounds great

I used one computer power supply cooling fan and it works great, everything in the control box is always well within a safe tolerance.

# 2 Will you use again a pool filter for the air inlet
and have you evaluated the use of automotive
filter.

I did think about using the auto filter, but opted to use the pool filter and again it works very good. I don't have a dust problem. Little dust find it's way in via the cracks I mentioned, but the proof is evident by the dust trail around the holes.

Here is a link of what i have in mind.

Well come your comments.

Guillermo.

Guillermo if I may make a suggestion .......... lets continue this discussion in my thread so others might benefit. Thanks J.R.

Nils, she does resale the items.
As a matter of fact ..... it's the customer you suggested I contact a few years back. Thanks again J.R.

Hi J.R

Thanks for your comments and wecome any other suggestions.

Guillermo.

I am sad to report that J.R. Hatcher has passed away. He was a friend here as well as on facebook and I was shocked to see posts of his passing today on facebook. I do not have any other info as of yet and when I get more info I will post it here. RIP J.R.

That is indeed very sad news. His first wife passed away while he was building his MM in 2007. May the two of them rest in peace together.

I am very sorry to hear that. He will be missed on this forum.
I think he was a very good designer and his rail grinding and dust shoe ideas were used by many.

RIP J.R. you will be remembered with fondness around the world by those you helped and inspired.

My feelings of J.R.
Inspired most people, motivated many and helped all who asked.
The community is poorer for his loss.
Thoughts to who he left behind.

R.I.P. J.R.

JR, a man who not only inspires me and many of us, but a man of a good hart that was surely be praised by its steps & passage among many others than us. A man whom we've had the good chance to have among us…too !
It was a privilege to exchange with you.
R.I.P JR….. we thank you for your great contribution.

R.i.p. Jr.

R. I. P. Jr.

This is a sad week.
I had a great, productive time working out the methods that we all enjoy in the MM machines we use today evolved from Classic to Mamba with JR personally. He was a great contributor to the MM community. May he and Rose rest in the peace they earned.

My heart goes out to his family during this time.

Peace my friend.

Sean

Indeed a sad day. He will be missed !!

it is always a sad news to learn something like that
rip Jr

JR

Helped a lot of builders with their machine. I am sad to hear of his passing.

JR was a good guy talked to him several times always ready to help,
he will be missed.

JR was inspirational and encouraging. We were lucky to have him in our community, and we're lucky his contributions live on.

In case anyone wanted to see JR's obituary,

John Richard Hatcher

I was greatful to spent a littile time with JR a few weeks ago he was as happy and free as he could be, I started to break down and shed tears as we talked, with his great sense of humor he ask Gene whats wrong? everything is ok I am healed I am ok GOD is in control, He was not afraid one bit he knew His Lord and Savior he knew he would be home soon, it was a pleasure to know JR an his family he was a wondeful man, father and husban, who would give the shirt of his back , JR RIP brother may God Bless you and your Family

Gene

What a shock to hear this. RIP JR.
He was a true friend

Rip j r

Rest in peace JR.

A true inspiration to us all at the very beginning of the Mechmate community! Reading his posts inspired me and made me believe I could really build this Beast. The world has truely lost one of its greatest.

May your family and friends find peace in their hearts in these difficult times. Rest in Peace JR.
