A great idea. I need some soon for a new camera setup.

Might have to try that. Which kind of lubricant is best, do you think? Machine oil? Silicone based stuff like from bike chains? Vaseline? KY? :-P

All the best.

Thanks Ausrock, I will certainly do my research.

I know exactly what you mean... thanks for writing.

A few months back, I asked for expressions of interest about who would consider purchasing custom adapters/parts from me if I made them, the responses I received were promising. So I will now offer this service as of now, and to the best of my ability! If you need adapters, with threads or bolt up flanges, or other parts, shoot an email to me at, scastrophotography@outlook.com or give me a call on 0428650851 and we will see what we can do.
Suggestions are welcome, for example, what are your thoughts on making variable threaded extension tubes of different diameters for when getting the that spacing right is critical...


Cheers,
Joshua Bunn

Hi M,
There are many, but mostly grease consistencies so that the stay in place. They are referred to as anti-seize or anti-galling lubricants if searching for them. Try the loctite brand (not the glue ). We used to Silverplate stainless steel thread inserts to reduce galling.

Best

As far as the warranty is concerned, I'd make sure that you're not being taken for a ride if the design is not correct. Warrant your workmanship by all means but be careful that is all you are warranting and the materials obviously. If it is made to the specs requested then it's not your responsibility for poor design.

One of the big differences in quality v's cheap machining is the finish of threads. Once cut threads work fine but are bitey and noisy if you run a second cut to remove the tip of the thread and run a cutting compound through the thread after it has been cut 2 or 3 times, it effectively sands the threads smooth giving a much better and smoother result. Also keep the material cold while cutting. If it gets hot, it expands and then when it cools it becomes tight and becomes hard to use.

Good luck with it. Sounds like you're on to a good thing

Hi Josh,


You certainly have my support for this endeavor of yours! One thing that has really frustrated me about dealing with the well known person in the USA is that he is very reluctant to give any help whatsoever in figuring out whether something will work or not. For example, it might be very difficult to see how he arrived at a back space measurement particularly when the part ends in a dovetail. In all of my dealings with him he just won't resolve a question like that. From a liability standpoint I can understand that position but it can be maddeningly frustrating because as has been pointed out mistakes are very costly. For sure you are going to receive many questions especially about camera spacing of flatteners and reducers. I think you will need to proceed cautiously. Hopefully you can provide some advice without taking on liability. That will be the trick. Also, how will you handle requests to mate something with a perhaps well known part that you don't have on hand? It seems you will somehow need to gather together a rather massive data base. In the beginning I suppose you can pick and choose your projects and simply inform customers that they had best generate the specifications themselves for you to follow.


Good luck!!
Peter

If exact measurements and specifications are given then there is no room for error. If any mistake is made and it doesn't conform to the specs given then the adapter should be remade at the supplier's cost. If the adaptor was made to specs but for some reason doesn't fit the purpose then it's the user's problem.

Hey this a great idea we need more local stuff like this. I recall the pain getting an adapter for my Pentax refractor. For some reason Japanese people don’t like diagonals... everything is designed straight through.
One other thing to consider is with a bit of marketing once you establish yourself you could be exporting in the other direction given the dollar exchange at present.

Thank you very much Peter!
I realise I'm going to be asked questions and most likely be asked of my opinion, some of which has already happened, which is great.
You raise some good points Peter.
As for matching parts, I may request a part be sent to me from the customer (I have no issues paying the postage there), so I can match it. Thread sizes are made to a specification, and as long as I follow them, the parts should fit. Having said that, I like to check the part fits before sending it off. So yes, I am building a "library" of adapters, threads etc.

Yeah, I thought there could be a market there, thanks for your input Netwolf!

Hi all, I am still doing these custom adapters, so if you need something making, got in contact with me and we can go from there

I've had 5 customers with more wanting work done, so I am happy with the start and great full for the support from other IceInSpace members


Cheer, Joshua

I had a new part made to connect my Riccardi reducer to Feathertouch and a large flange sent to get modified. Josh was happy to take my calls and questions to work out the best solution for what I was trying to achieve. Very happy with the results and I advise anyone looking for custom adapters to consider Joshua.
Cheers

Hi All


Just thought I'd let you know I have just recieved a custom part from Joshua.


He was very helpful when discussing the part, and it looks good and fits nicely.


Now I just have to pull my finger out and use it!


Not cheap, but, that's what good custom work is.



Philip

I employed Joshua to make me an adapter and I'm very happy with it. Fits perfectly and is neatly finished. The equivalent adapter from PP would have cost twice as much. Recommended.

Pillar extension DM4 mount to surveyors tripod

Joshua has just made me this custom pillar that had its challenges to make it right for my surveyors tripod and DM4 head and he absolutely nailed it ,Measurements perfect to the mm made from aluminium with a quality rubber coating where it connects to the mount and the tripod and just feels quality,


Many thanks Joshua
