Hello all,

The feet on the rear of my 335 are crumbling apart, literally!

I talked to Walter at Sphere and he has nothing even close, and searches on the net reveal nothing... so, I am coming to the group to see if there might happen to be someone who has any extra rear feet (Tek PN 348-0425-00) or even just one, that could be spared (or loaned?) to me as an example of a complete foot?? I don't know if they could be 3-D printed or cast, but I don't have even one that is complete... mine are all crumbled.

Here is a picture of what it looks like (borrowed from the internet):

Thanks for any suggestion or help you can provide.

My 335 has ONE good, complete foot that I would loan out in the hope it might lead to the production of four new replacement feet.

It can be done. I've 3D printed feet for the 465 based on this model I
"designed" based on the original feet:
. Printed in PLA, they are
functional but I wouldn't bank on them holding out for every day use.
Someone with a bit of 3D modelling ability and an original foot should be
able to craft a suitable replacement for the 335 too. Printed in something
a bit more durable would work and even if they weren't as good as the
original, you could have plenty of spares.

Why not "print" a foot and use that
to make a mold. Then you can cast
them in more robust material.

This is such a common malady that a few people have developed
replacement feet.

One reference is /g/TekScopes/message/144184

And I've bought a few sets from Fred Usack on ebay, and can vouch for
him (I don't know if he is on TekScopes):




These are for other models, but given some basic measurements, Fred (or
others) is likely able to produce feet that are compatible with your
model, even if not identical to the originals.

Hi Lee,

I have been considering making a mold, but I am going to have to learn how... If I can figure out how to do that, without harming the example, I will get back to you on this...

Thanks for offering such a valuable piece... as it seems they are "unobtainium" these days!

Phil

Ps thanks to all who have made suggestions, so far... I am going to follow up on them.

Hi all,


I'd be willing to undertake the 3D modelling and printing with a durable nylon material if I could get my hands on a reasonable existing foot to take measurements from. I've already developed models of 465/475 and 453/454 feet that are near identical replacements for the existing feet.


In exchange for the use of your foot, I'd be happy to provide a set of nylon printed feet gratis to upgrade your existing feet. I would then make these feet available to the community through the same channels I use for my 465/475 and 453/454 feet.


PM me if interested.


Thanks,
Jeff

Hi Jeff,

Are you N0dy?? If so, I just emailed you about your 400 series feet.

If your process is nondestructive, maybe we can get Lee H. (on list) to volunteer his one surviving complete foot for measurement...

I have a picture of the foot, upon which I have drawn (crudely) the measurements, that I will put that in my folder on the server:

/g/TekScopes/photo/33014/2?p=Name,,,20,1,0,0

If it comes to pass that Lee would allow you to measure and print out feet... he should probably be the one to receive your kind offer of printed feet, not me, but I would buy a set from you.

Phil

Hi Phil,


Yep, that's me. And I did get your email and have sent a response.


What I do is entirely non-destructive. I just need to take measurements from the existing foot

Jeff

Phillip Potter, Jeff Davis N0DY -

It would appear you two are on the same page so I would be more that willing to send my one good 335 foot to Jeff for modeling and creation of new feet. Jeff if you will pm me your address off group I will get the foot out in the mail ASAP.

Lee NV8YH

Hi Lee,


Thanks! I'll get to work on it as soon as the foot arrives!


My address:


Jeff Davis

12 Galora Lane

Ladera Ranch, CA 92694


319-431-3846 (cell)


Regards,
Jeff

Lee...

Thank you for your willingness to help out a fellow Tek 335 owner in need!!? :)

Thank you, Jeff, for offering your service, as well...

If I can help with postage or ?, please email me off list and I will be especially happy to assist in any way I can.

Phil

Jeff, the foot is packaged up in a USPS Small Flat Rate box. Hopefully I will remember to mail it tomorrow and you will likely have it Monday. You should have received an email from the USPS with the tracking number; if not yet then you should when they have the package. Just remember to save my shipping label for the return address.

Now to find a source for 2445 and 2430A feet....

A while back I found a guy named Bob Haas, who was selling molded 400 series feet on eBay, try and make up some 314 feet (same as the 335.) I sent him a couple of feet and he made a couple of sets for me but he said they were too hard to make and weren't of the quality he could sell. I'd be interested in how this goes and might be interested in a set myself.

Thanks,
John Clark

a stash of 3D models for Tek replacement parts cataloged someplace, and/or
to have them listed on these print services.

I modeled the PCB bracket I needed for my FG504, but the PLA prints I got
from the 3D printer I have access to delaminated as soon as I put a screw
to them. The ShapeWays nylon print, however, worked just fine (see <

and I know other people have had luck with the same print.

I priced out your thing on Shapeways, and the two materials/methods that
look likely are:

- Strong & Flexible Plastic Black (Selective Laser Sintering): $8.98.
- HP Nylon Plastic Black (Multi Jet Fusion): $17.96.

though perhaps it'd be possible to bring down the per-item cost for e.g. a
set of four by optimizing the design...

3D printing can be a bit picky about settings. The smaller the layer
setting the denser the part, and the more rugged it will be. Extruder

Hello all,

Here's an update on the project to develop replacement back feet for the Tek 335 scope. Lee Houde has graciously provided me with a sample foot, which I've measured and modeled. I sent a first set of samples to Lee, which he fitted to his scope. They worked and were usable, but not perfect. Lee gave me some great feedback and some photos which I used to revise the models and print a second set. They're on their way to Lee now. With any luck they'll be a great fit and I'll send out another update to the group at that time.

If you would like another tester, I would be happy to volunteer.
I have a 314 and a 335.

Thanks,
Bert

Hi Bert,


That would be great. Even though the foot has the same part number on the 314, it would be good to confirm correct fit on that unit. Let's wait until I get results from Lee - I actually sent him several variants to try to get the best fit. Once that's determined, I can send you a sample of that size.


PM me your address, please.


Jeff

If you have an original foot, I can make a mold and pour plastic feet. I've already done it for some older Yaesu and Kenwood rigs.
