I need a part made

1162 Views 60 Replies 10 Participants Last post by  JayArr
Hi All

I was directed here from the woodworking forum and it was suggested I see if anyone wants a project.

I want a plastic piece made for a Craftsman Radial Arm Saw. You can see a picture of it attached. It's about 3.5" x 3.5" x 1.25" tall.

It was made of thin, brittle plastic and it broke on almost every saw I've ever seen. I was lucky enough to get this sample off a saw, it was already cracked and broke apart as I was removing it but I saved all the pieces and glued it back together.

Since it's symmetrical I'm hoping that one half can be scanned and then mirrored in the software to create a full, unblemished, image. I'd like at least three made, I could poll over at Woodworker Talk to see how many more could be required. The maker could then sell them on eBay or etsy etc.

I'd like the new ones to be made of a thicker more durable plastic, they will get a lot of vibration since they are on the side of a saw motor. I'm willing to mail my sample to someone who wants the gig.

If this is the wrong forum I hope that the mods will move it to the correct one.

You should really read an entire thread before responding, it keeps your foot out of your mouth.

Alternately "copy and paste as a quote" what you're replying to so those of us who have read the entire thread have the context of what your referring to.

Your quick response looked to me like you were disrespecting RT3360, that may not have been your intention but it was your result and sometimes you're judged on your results not your intentions.


If the original part broke, and several of them have broken, then the part is obviously designed wrong from the factory, so it would behoove the OP to design something bigger, better, stronger.
I have heard this logic before and it seems sound when it comes out of your mouth but completely neglects age and economics. If the part originally lasted for 20 years before it broke is it really a good idea to over engineer a new one so the new one lasts 30 years? I think not, A decent part at the lowest possible price that will last 20 years, like the original, is my preferred solution. I have better places to spend my hard earned money than a super-engineered dust cover.

The problem here is not that the original part broke it is that I can't buy a replacement. If Sears sold this plastic part for $20 I would not come here to commission a better engineered copy - I would just buy a replacement from them every 20 years.

My skin is thicker than that. The OP stated that he glued the original part together, and I suggested he send THAT PART to someone who can scan it, and design something better to replace it.

Noted.

Some people LOOK for reasons to be offended. There was no disrespect in advising him to find someone who could build a better mousetrap.

Really? The price of one single plastic 3D printed part would change so dramatically, if it were printed 1/8" thicker? I don't think adding 1/8" of thickness to a part, or printing it out of a tougher material qualifies as "over-engineering." Did it break because of it's AGE, or because of an IMPACT? A brand new 3D printed part that is printed on the same WEAK design as the original part will also break, and it won't take 20 years for that to happen.

Quite frankly, a simple square or round steel tube with two TIG welded tabs and an end plate with a hole would work. There is no need to follow the contours and facets of the original design. it is only a protective cover. It is not air tight or water tight, and no amount of CAD designing of a new cap will increase the value or the utility of the old tool. It just needs something that serves as a COVER.

The problem here is not that the original part broke it is that I can't buy a replacement. If Sears sold this plastic part for $20 I would not come here to commission a better engineered copy - I would just buy a replacement from them every 20 years.
A soup can and some duct tape would accomplish the same goal.

In the Space Race, NASA hired the most brilliant scientists and engineers to develop a pen that would write on paper at any angle and at any temperature in outer space where there was no gravity to assist with the ink flow. Millions of tax dollars were spent developing this space age pen. The final product was touted by NASA as a great accomplishment by our superior Capitalist system, and our politicians tried to shame the Russians by boasting about this pen's ability to write in any position and at any temperature.

The Russians responded with four words: We use a pencil. :ROFLMAO:

I am the OP

If you read the whole thread you'd know that.

The pencil story is a good one but not true.

It's obvious you and I have different opinions, luckily there's a solution for that that avoids flame wars that disrupt the general tranquility of the forum

If you hover your mouse over my avatar (the big purple J) a box will pop up. In the top right corner are three dots. If you click on the three dots a smaller box will pop up that says "ignore"

Once you "ignore" me you won't see my posts anymore.

I don't want to argue with you anymore so I suggest that you ignore me. I'll do the same and ignore you and we will stay out of each others threads.

It's sort of the forums answer of "agree to disagree"

JayArr

BTW - Congratulations, you've been here for 7 posts and someone already ignored you, that has to be some kind of record.

"Argue"? I thought we were having a civil conversation about my single response to a post. You accused me of "dissin'" someone (I haven't heard THAT term since the 70s :ROFLMAO: ), and I politely responded to inform you of the fact that my response was to the original post, and not to any previous responses.

Read the entire thread? WHY? Some threads are 25 to 30 pages long in these forums! Oh, I see. You believe that I need your permission to respond to the original post, and when I respond, I have to make sure that someone has not already responded with the same answer, and I have to make sure that YOU deem my answer to be worthy. I get it.

The problem is not that I responded to the original post. The problem is that you concluded that my reply was to the last REPLY, rather than to the original post. If the thread title is, "Should I buy a 1964 V.W. Bug?" and 20 pages into the thread, the topic morphs into the reply, "I think pit bulls are the best choice for a good dog!" and I then post a reply with, "No. Look for something much better" ... have I told the OP to choose something other than a PIT BULL? Or have I told the OP to choose something other than a 1964 V.W. Bug?

Go ahead. Stick your fingers into your ears and yell, "La La La La La!" I do not live and breathe based on whether your opinion matters.

What hoops must I jump through, in order to post a JOKE here?

It's obvious you and I have different opinions [..] Once you "ignore" me you won't see my posts anymore.
Why would I ignore you? Your posts are valid and informative. You are easily TRIGGERED, however.

How will I EVER be able to continue with life now? :ROFLMAO:

I picked up the parts from my friend today. This time I decided to check some dimensions against the original part before shipping. Unless I find something drastic, they should be in the mail tomorrow. Overall in side by side views, they look to be pretty good.

Height slightly more (allowing for additional interior rib height).

Tabs are the right height
Rectangle Gadget Wood Audio equipment Bumper

Width looks good.
Camera accessory Audio equipment Carbon Gas Cable

Large hole is slightly smaller, but hope it’s okay without trimming.
Gas Tints and shades Audio equipment Circle Metal

Tab width and location looks about right. Hoping mounting hole is about right too.

So unless I find something drastic, they should ship tomorrow.

Jeff,

I checked the dimensions and believe they should work for you. Shipping tomorrow. Let us know what you think.

And shipped.
EDIT: Tracker is saying delivery is expected by Friday.

Good to know. Thanks for letting me know.
Lookin Good!
Looks like the package may arrive today (Wednesday). It’s already in Seattle.
Checking to see if you got them?
Yes, I picked them up and they fit!

I'd call this a success!

I'll try to find some time to post some pics of it installed.

See post 47 for part to part comparison.

Only curious why the bottom wasn’t in as far as the top.
EDIT: The mounting holes are the same distance from the outer wall, vertically.
